I have charged it in the morning until it was full, and started playing with it.
It was on for 9 hours until the battery was completely dead.
I used it since 11:30 until 3:30pm, then I left it on standby for a 2 hours (battery was at 14%). I came back used it for another 2 hours, and it went dead.
Everything was on except for bluetooth and GPS.
Android Operating system used 83% of the battery and all the other application were under 5%.
I did quite a bit of browsing, photos, movies, youtube, downloaded some apps, etc...
What do you all think about the battery performance?
At the moment it is charging and I will leave it plugged in until the morning. It is also turned off.
What are your experiences? Opinions?
9 hours only? That's not good ... But probably you have quite some widgets that actively sync etc. etc.
i wouldnt worry to much as you probably just received it and you must have played with it for a while, and also try turning off the auto update of facebook, email etc etc
thats kindda dispointing, ... even with updating i expected it to last at least one full day, I mean when they put many widgets they should take into consideration the battery life ... hope its cuz the battery is new, and needs some few charges to feel maximum capability
As I said, I did have everything on apart from GPS and Bluetooth. (including updates).
And yes I did use it for 6 full hours (medium screen brightness).
Downloaded apps, watched videoclips, played some flash games, wrote e-mails, wrote texts, browsed the internet, etc... funnily enough I EVEN made 1 (one) phone call!
I wouldn't worry about it though. ALL my phones only lasted for about 8-10 hours the first day when I got them.
Doesn't new Lithium-ion battery needs a couple of charging cycles before
reaching optimal capacity!?
Would be nice if someone could update us in this thread about the battery life when you've had it a few days and it's being abused less
We must however point out a couple of things regarding the Desires out there at the moment, although we certainly do not wish to discredit anyone else's reviews.
We have been informed by a reliable source that some HTC Desires have been out for review for several days now, but these devices did not come from the same source as ours. These early versions did not contain the final ROM that we have been waiting for and I am reliably informed that those devices will have essential features missing. They have also had problems with the OS crashing and serious battery issues which is clearly down to the fact that Google had not completed the ROMS when the devices were shipped.

Could It be possible, that t-Mobile did not ship the Desire with the latest firmware?

I believe you are totally right.
I had my new HTC Desire from T-Mobile delivered today. It's a good phone but I have a problem. They sent a phone with pre-release software installed. Every screen has a watermark stating "HTC Confidential" and numbers.

Let's wait ~7th April and then we will see true battery life...
I'm fairly sure that 9 hours of constant use is pretty damn good for any device. If I use my Touch HD for browsing the net/listening to music/ syncing etc it will die in far less than that.
Remember that it is a miracle that the iPad lasts for 10 hours of constant use, and thats got a massive battery in it!
So yea get used to it! At least while you are playing with it being a new toy and all.

dont forget that the iPad has 9.7-inch (diagonal) LED display, so that shouldnt be a reason, and dont forget that the Desire's display is AMOLED which should be a battery life saver.
For the OP, if you could try using it the same (constantly) but disable the live wallpaper

Agree with the AMOLED, but it's running a 1ghz processor along with the already perceived power hungry android.... Gotta admit that if you expect it to last more than a few hours of playing with, will be sorely dissapointed.
Compared to my HD which had a 528mhz processor but lcd screen, which lasted less than 10 hours when playing with non stop.

It's not the same thing. "LED" is a backlit LCD-display, AMOLED is an active matrix OLED-display, completely different technologies.
TFT-LCD's use a backlight, OLED's has active pixels that light up per pixel and does not need an extra backlight.
The battery life is really poor.
I went to bed last night with it fully charged and this morning it was completely dead. Albeit I left meebo running in the background along with lookout and advanced task killer.
Nothing was set to update as I've deleted the friend stream and rss feed.
I'm pretty sure this phone should last a lot longer than 9 hours on standby.
If you have read the whole thread, you'll see that there might be an issue with the pre-released models. Unlocked/retail phones coming out next month with latest software will probably not have this issue.

I think someone should actually test turning everything off except gsm. No data connections, no updating of anything. No GPS, bluetooth, sync, no applications running. See how much it goes down overnight with everything off.
That could maybe be a good idea, just to see how much it goes down. But if you can't use the phone at all, I just can't see the point of having t his phone. It's made to be used and you are supposed to be connected at all times, so if HTC has made this phone with so bad battery performance, that just basically sucks.
On the other hand, it seems that the final ROM from HTC was just confirmed at Google this friday, so im guessing these early phones out there does not have the final ROM.

My Nokia E75, i run wifi all day, with push mail, and Zozoc (WiFi/GPRS Messaging client) and i can easily go through one whole day (and few hours). the screen is TFT, non-touch, and small.
I know that we cant compare cuz they are entirely different, but the point is, the battery life should not be (and i hope it is not) that bad, even when running apps in the background. one day (or few hours below that) should be decent.

The OS in the T-Mobile versions have already been approved by google, so its not a pre-release.
and i agree, someone should try to stop live wallpaper and updates (just use it as simple phone, calls, messages and a little bit of WiFi) and see how much that goes
I quote the following from the first detailed review from techradar
The battery in the HTC Desire was 'only' a 1400mAh effort - we'd have like to see a 1500mAh option there, as is the case with so many other smartphones at the moment.
We're also a little concerned about the battery life - it dropped rather quickly, and although you'll get a day's worth of use out of it under normal use (ie web browsing, calling etc) it can drop a little alarmingly fast at times.
We had a little look at what was munching on the power so much (thanks to the Android battery meter) and it seems to be the widgets (in particular FriendStream) and synchronising that's taking a lot of the power, along with the constant flicking to roaming networks and back to 3G.
We found a big increase in battery life if we stopped updating Peep, Friendstream and emails all day long, and when set to '2G networks only' the battery life also improved to three days' use without problem.

this seems good, this is decent! i dont use 3G much, i would probably update the friends stream on demand, and with a little bit above average use, i should get 1.5-2 days without problems (based on the review)
No I want some people who already have the desire to try this and come back with the result
A very simple quick question : Is the battery life of the Desire HD better or worse than the original Desire? (because right now the only thing that is between getting the DHD or the Desire is the battery life issue) I am much satisfied how the old Desire performs in batterywise (by reading the forums and reviews) but all the bad comments of the DHD dreads me to make the deal.
Have anyone used (or better owned) both devices and know any differences of these 2 devices with same level of usage? Can actually the improvement of the CPU compensate the drain due to the screen?
Some facts I expect from the device:
1. Dont need hourly updating with twitter fb etc or regular sense Sync. (once or twice a day is more than enough)
2. Looking forward to have a fairly moderate use of the screen for browsing ebooks etc.
3. Not heavy on making long calls.
4. Dont want to use spare batteries and nowhere to charge during the day after leaving home. So it MUST last 24hrs.
PLEASE share your experience, or I m afraid I might endup with the wrong phone for the next 2 years! Thank you all for your valuable comments....

@junta_mpb Thanks for the instant reply. So I ll take that DHD can last the day by my usage pattern right?
Ok now Much more convinced to make the deal with DHD .
So I presume the battery killer about the DHD is the screen. And for a day that I might need more juice till late, I spare the screen usage and be ok right? I also saw that the 2G can go upto 9+hrs! So it seems calling may not have a big impact.
Just curious how much do you think it will last, if I got a DHD, with my usage pattern, with additional 30mins gaming a day? Thanks a lot for the replies.

Text and calls don't seem to affect usage a lot. Based on what you wrote, I would say reading your books will eat the most out of your battery. I'm going out on a limb here and will say you should easily get more than 14 hours with heavy usage/e book reading. By heavy I mean more than 3 hours screen time.
3g is the biggest drain of the battery, in my experience and even with it on, I still get more than 14 hours with lots of surfing with around 3 hours screen time.
Standby drain with hourly sync takes 1% per hour.
Cheers from my DHD.
My battery is better than normal desire. I can actually playing most of the day with it and still have some juice left till I plug it in....

@junta_mpb an @MattSkeet Many thanks again. Getting a solid picture now
Just another quick question, do you keep the syncing, email and social network updates, to frequent checking (for ex 1 hr basis) and use GPS daily?
And how much "screen time" roughly do you get until the battery level gets critical?

Mine is set to hourly sync. Screen time is typically around 3+ hours.
Again, this usage gets me to 30%. I usually change then.
Cheers from my DHD.
I am fortunate enough to have both devices. I see myself as an average user and I easily get through a day with my dhd, 24hrs plus.
The battery life on my desire is abit better but not by much as I always plug it in every night in anycase.
I have Facebook, emails sync every hour, WiFi on the whole time, 30 to 40 mins of gaming, and listening to some music when I'm bored, 10 to 15 min on the web, atleast 4 calls made or received and texting the whole time. This is average usage for me, so I think you should be fine.

PC Pro put the DHD at the bottom in its battery tests, lower than the Desire. But in the alternate universe inhabited by some people in this forum, I'm sure the Desire is better.

@bobbyelliott maybe functions that didnt much affect the battery of the Desire (screen usage I presume) due to AMOLED, have greater effect on the DHD, and vice versa?
But getting mixed reviews is confusing. Shame that I dont know anyone with a DHD to check hands-on. And the battery needs some time to adjust, as I ve seen in this forum posts, and they had done the battery test straight out of the box I think?
Anyway I m still leaning towards the DHD for its big screen. But I dont see a point buying such a powerhouse with so much underpowered battery.
Maybe should I wait and see if something like Thunderbolt gets available for sim-free?
had Desire for 6 months and am a DHD user for less than 3 weeks now..
battery life is very similar, maybe slightly better on Desire..
am a light user; 5-10 sms per day, a call or two, sync only gmail & weather (every 2 hrs).. some web surfing (30 minutes) and installing/uninstalling of apps..
with above usage i charge battery every 2 days
I can't compare with the Desire (I'm comming from a Touch HD - the greatest phone of it's time ), but I can easyly get through the day with one charge. Obviously the screen is the biggest drain, so if you need the battery to last more, you have to limit your "screen time" and I keep my brightness set to auto. Due to the nature of my job, I make a lot of calls (maybe 40-50 mins a day), browsing+XDA ~40 mins a day, ebooks for about 30 mins (screen brightnes set to minimum for that), and when I have to use GPS (very rarely), I always charge the phone during that time, because I use GPS only while driving. Also I'm almost always on 3G, wifi and bluetooth always on. I don't use facebook or twitter, but I sync the news feeds, weather, POP3 mail, gmail is set to push, sense is also syncing... and I think that's about everything worth mentioning.
I rarely play games though, so this might bring the battery down if you do, but I think you can still get through the day (actually that's 16 not 24 hours - you have to sleep sometime ). Also if you have a "battery heavy" day, you can always put some juice in the phone while driving home after work.

Here is roughly my day.
Wake up at 6am phone off the charger walk to work and play on it for about 15min.
During work I play (same games some internet some engadget ) here and there for about 10min plus 30+ on my break so all together will be more than 1,5hrs finish work at 4pm and my battery is at about 60-70% get back home surf the net for half hour and turn on hotspot (don't have proper internet at home) this itself drains a lot of battery but if I don't use hotspot and play with the phone instead I manage to get till about 5 5,30 till phone battery goes down to 20% and this is very heavy usage. Had days (Fridays ;p) where after work I didn't use the phone much just few text and it lasted me till next day with about 15% left.
Things is I don't call much. I have 900min and this month used only 100 (lol)
My updates are every 3hrs, push for gmail (i have one account for my regular emails and one just to store contacts without any crappy email addresses) gmail used as exchange account.
Screen on 23% brightness.
Lately battery is draining fast because I've installed whatsapp as my miss is abroad so we save some pennies

[SOLVED] Final Decision : Going with the Original Desire!
I was doing some more research, and Decided to buy the 'Old' Desire
And Thank you all for your contribution with experiences and thoughts, guys trust me it did help eventhough I didnt go for the DHD !
So for everyone I m gonna breakdown the reasons for my decision. (at least on the paper Desire outscored the DHD)
Battery Life
A huge factor if not the critical. I found that Desire has better Battery life than DHD, in comments I found Desire "Only lasts a day\ have to recharge everyday" etc and with DHD I found "Battery life is abysmal dont last the day\ have to plug in for midday charge" etc, but I know some of you guys anyway manage to keep the juice to last the day, anyway Desire 1 point...
Quadrant Score
http://smartphonebenchmarks.com/ (with 1GHz ranking) WOW this is INCREDIBLE ! Desire outsmarted the DHD came up with 3rd in benchmark with 1. Samsung Epic 4G 2. Samsung Galaxy S 3. LG Optimus 2X (dual core anyway) so its actually second place considering both first two are identical. (now who says Desire is not for gaming???)
Techradar No. 1 phone of all times
with DHD on the 3rd place http://www.techradar.com/news/phone...e-phones-in-the-world-today-645440?artc_pg=21
Pixel Density
Not a big point but anyway a point for desire.
Looks
DHD looks minimalistic on the face and Desire looks good too. And the physical Buttons on Desire... (are they better than the capacitive counterparts?)
Design
I dont like the patchy design of the DHD to be honest. Looks less durable and what about the gap between the bottom door? Cant put a custom cover to get bigger battery even. And the kickstand is utterly useless for many if used with a casing which is mostly the case. And the camera protruding out is menacing and accident prone.
Size and Weight
164g Vs 135g big deal. Pocketability issues, bulge, and for the long hours at the University it's gonna cost me some uncomfortable time.
Camera
Desire's cam is not the best, washed off colors etc.. but is the cam on the DHD fantastic? Nope, focus errors, too much sharpening etc. But HD footage is really cool. Not a big improvement worth considering I think.
DHD issues
Reception issues, (death grip?) , Sometimes lagging (occational 100% CPU usage, saw in a thread in XDA) Desire's problems were ironed out mostly I guess with the hardware revisions. No more overheat etc....
Loudness
Desire is louder than DHD http://www.gsmarena.com/htc_desire-review-468p8.php and http://www.gsmarena.com/htc_desire_... my Desire. Any more comments are welcome. :D
Just one more thing to add, I think the DHD is an overkill. They've got the same snappy so the apps should run at the same speed. And android doesnt have too many 3D games (yet) and I think Desire will do fine until at least the end of this year. Then the dual core phone will go mainstream and prices will fall. So even with the Adreno 205 I dont think DHD is leaps and bounds ahead of the Desire in technology aspect. (buy anyway we can port the DHD rom to desire !!)
Cheers.

It's not the same snappy. Desire hd has the second generation version which uses less power and overclocks better.

This review shows the DHD battery lasts longer:
http://www.fastbutter.com/Article/227/HTC-In-Depth-Review--HTC-Desire-HD
"Despite Desire HD has a battery of 1230 mAh it sweep the carpet with its older sibling Desire with its 1400 mAh battery. When Desire goes out after almost exactly five hours Desire HD still have 19% battery left and rolls on for one hour and two minutes more- despite the smaller battery."
I guess the people with battery problems are having the cpu draining /init bug.
Hi Guys,
I actually have a HD7m but my dad quite liked the 4.3 inch screen and was now asking me to buy a similar handset. We went out and he was quite impressed with the Desire HD.
But the catch, when I researched online, I found out the battery issue on practically every thread and community.
Now my problem: He is an old man and can get cranky at times. Currently owes a Nokia C6 and is pissed with the touch screen. So is it wise to buy him Desire HD even with the bad battery life?
Or worse case scenario, I swap my HD7 for his Desire HD????
Should I go for it or should can you guys suggest something else equally fluid??
It doesn't have battery issues once calibrated. I have 1-5mA battery drain on standby, that's even when running MSN and CallerID2Voice App in the background. And I can still get hours out of it when using it. Just recharge it every-night. I doubt your dad will be a smartphone addicted guy.

Hey,
Thanx...no he isn't a smart phone addicted guy. But the battery was so obvious an issue, I had to ask the experts here. Also, what exactly do you mean by 'calibrated'?
I mean, I have been an Android user before, but not quite sure what calibration is ?
He is a simple user with checking some mails everyday, music and some websites may be...thats about it, HTC Sense and all makes no difference to him actually...
If its battery life your after, buy a Johns Phone, you get 3 weeks between charges.
After you battery has been "run in" and calibrated you will get at least a day with light usage. Remember this is a powerful smartphone.

The battery calibration concerns only those who are using a custom rom. (here's a short article with app that does it for you if you're interested). I wouldn't recommend the DHD for my own father. Whatever you do to it you'll almost always have to charge it overnight, with stock rom it could be even twice a day. This isn't a problem for smartphone enthusiasts, but for oldschool people (like my father) who think phones should last a week without charging this can be quite off-putting. The DHD is also starting to get kinda old already, so you might wanna take a look at some newer phones. A good alternative could be the Desire S, as it has almost the same features with a slightly better battery.
And to those who can't admit that the DHD has bad battery life I just have to say that the out-of-the-box battery life could and should be a lot better. To get it lasting as it should takes a bit of effort which shouldn't be required from a normal user.

Thanx so much...that was really helpful...albeit your explanation on battery life, I just wanted to add that he was in love with the 4.3 inch screen...and only HD7 is the other device with that screen size...So I think Desire S is also a good option...let me check with him...
Again, Thanx!
depend on what you consider a good battery life, some may say getting a day is good enough, but some define good as atleast 2 days.

Absolutely right. I'm tired of hearing people evangelising that the DHD's battery is fine. It patently is not. Even when you severly rein back the device's features (features which HTC flaunted to get us all hooked), one ends up with 25-30% at the day's end.... And if you have a 'heavy' day of calls/browsing etc, you'll have to top up to get through the day.
But I still regard HTC as just about the best of a bad bunch...
Ok, sorry to hijack this thread a little.
The battery is fine, there are no issues with the battery. Your problem with the battery is that its small. Before you bought the phone did you not look into the battery capacity? I did, I knew it was smaller than the Desire's battery. Out-of-the-box it will act like any other lithium-ion battery that is just out-of-the-box. That "bit of effort" , what, plugging in your charger when it requires a charge.
These guides to correctly charge lithium-ion batteries are largely mumbo jumbo (charge to 100%, turn off, charge again for 250,000 hours, turn on, drain battery, rinse & repeat). Just charge it overnight, when your asleep.
Any smartphone with comparable usage will last around the same time and require a daily charge. If you want a phone that will last days between charges, don't buy a smartphone.
If you turn off all the bells & whistles, use 2G only and use it only for calls & sms', just like a regular phone. It will last days between charges.
If you want a powerful smartphone with a large screen, and lots of features, your battery is going to pay for it.

I'm not sure anybody on this forum expects days of use between charges - we're not daft. What I expect is to not have power-saving mode kick in by late afternoon when I'm nowhere near a charger, and I've not used the thing particularly heavily.
It's not right to conclude that others didn't read up on the battery before purchasing. You have no basis for drawing such conclusions.
HTC marketed the DHD on the basis that it's architecture was such that it didn't need a higher-capacity battery to do its job. Based on the fact that I'd had pretty good experiences with my previous HTCs, I saw no reason to doubt this.
In any case, just because you don't mind charging your phone part-way through a day, doesn't mean that everybody else should be happy with that.
I don't Say ! ^^

That's why I said that there are "oldschool people" (like my father) who think the battery should last a week. I don't mind charging the phone every night, but there are people who can't cope with such a "short" battery life. That's why the battery life of the DHD should be taken under consideration when buying a new phone.

The battery is fine, there are no issues with the battery. Your problem with the battery is that its small. Before you bought the phone did you not look into the battery capacity? I did, I knew it was smaller than the Desire's battery. Out-of-the-box it will act like any other lithium-ion battery that is just out-of-the-box.

Any smartphone with comparable usage will last around the same time and require a daily charge. If you want a phone that will last days between charges, don't buy a smartphone.
If you turn off all the bells & whistles, use 2G only and use it only for calls & sms', just like a regular phone. It will last days between charges.
If you want a powerful smartphone with a large screen, and lots of features, your battery is going to pay for it.

I didn't mean that the battery was bad quality or anything, just that it is a bit too small for such a powerful phone. And yes I was aware of the battery capacity and I don't mind, but again there are people that require more from their phones.
And the instructions to close connections when you're not using them and turning down the screen brightness etc. are plain stupid. I bought a smartphone so that I can get my email whenever and wherever and to enjoy the big screen and not so that I can receive emails only when I choose to and so that I have to squint to see something from the screen when the brightness is set to the lowest. This is just a couple of the features I need ofcourse, but for me it's important to always receive emails instantly and not only when I can afford to spend some battery on internet connection.
When I was still running stock rom I could barely get through a day at work (8 hours). I had mobile network on the whole time and the screen brightness set at about 50% (which I think should be used at 100% all the time to really enjoy the screen) I talked for about half an hour during the days, sent 10 texts and listened to music/played/surfed on the internet for about 3 hours in all. When I got home I had to charge it. This ofcourse is everything one could need, but there are smartphones with better battery life.
Now of ofcourse when I have a custom rom that's tweaked and everything there's no problem with battery life, but that shouldn't be necessary to do and it's quite a lot to ask just so you can have a decent battery life. That's why I was talking about out-of-the-box battery life.

If you want to receive emails and text, I find that GSM is fine for that. If you want to go internet browsing, just switch on to 3G.
Smartphones these days have basically a different definition of battery life to the old nokia symbian and similar phones of old. Those could go up to a week. Smartphones on the other hand are considered awesome if they can last 3.
I do have to say ultimately I think HTC sold the battery life a bit short on the DHD. 1230mah I think is really just making way for all the other top-of-the-line features that it had when it came out.
HTC have released a great number of variants of this phone now, all with better iterations of design and also with bigger batteries because of this.
1400-1500mah (or even above) I think is really what you need with a 4.3" display phone. 1230 would be far more acceptable for a <4" display. Although it can be made quite livable for a day or two with an excellent custom rom, I don't really think it's enough for a basic consumer using the standard rom. That and the speaker/audio out are the two biggest pitfalls of the DHD imo.
Sensation is now HTC's newest 4.3" phone which has a good 1500mah battery. I hope Sense 3.0 doesn't wear it down too fast!
Ultimate thoughts: Although it's a great phone, I think it's a power user's phone more than anything. You will definitely only get the best out of it by customising to it's best potential, which is also when you get acceptable battery life. If you don't, it really does seem a waste.

I had the same sort of expectancy out of the battery using it moderately during a day at work out of the box. However with custom ROM installed I have found the battery to last easily the whole day with the same usage and probably have approx 40 - 50% left after 15hrs on battery.
just my 2c

These guides to correctly charge lithium-ion batteries are largely mumbo jumbo (charge to 100%, turn off, charge again for 250,000 hours, turn on, drain battery, rinse & repeat). Just charge it overnight, when your asleep.
Any smartphone with comparable usage will last around the same time and require a daily charge. If you want a phone that will last days between charges, don't buy a smartphone.

I am extremely sorry but I disagree with u completely. You are talking as if you buy an expensive car but dont drive it too much as it eats a lot of fuel. If you want to just drive around, why dont you just get yourself a mopet. The point is, i have bought an expensive car TO DRIVE it around. If I buy a smartphone and not use its SMART features, why am I buying it for??? If I practically shut all the reasons why I bought this phone, WHY the hell am I buying it??
There is an old saying that comes to mind that it takes guts to stay in the minority. If the battery is flawed, ACCEPT it.
Anyways, I have got my answer. Thanx for your reply nonetheless.
As everyone says depends on usage.
For one thing i went from 80mA down to 8mA just by updating the radio which came stock.
Now with a different rom and kernel I get -1mA on standby, juicedefender is also a nice app. The battery life depends on your setup though, I easily get 2 days of moderate use/music/games/calls etc.

Hey thanx man...But was just wondering, with very moderate usage, will it still be over in no time?
Also, the other thing worrying me is the memory card issue...I cant afford to lose one card after another once I buy an expensive phone, u know what I mean...
The battery life is acceptable with moderate use on stock rom, if you're a power user you will have to stay close to a charger
There's no memory card issue from the DHD's part, it's just the crappy "freebie" sdcard (samsung?) which comes with the phone that stops working. The people who are complaining that the DHD breaks sdcards are those who buy cheap, bad quality sdcards or get a warranty replacement for the original one, which will be just as bad. The solution to this is to buy a better quality microsd card (costs about 15€) if the original stops working. Mine's still working great though.

After receiving a replacement 'new' phone, and having problems with my SD Card from the very second it switched on, I complained to HTC about the issue and the man on the end of the phone admitted around 500,000 phones that had been dispatched has been shipped with KNOWN issues & SD Card incapabilities. If you went out today and bought a brand spanking new card, in theory the phone WOULD NOT and the SD Card WOULD NOT fail.

I don't mean to hijack you here mate, but you assume/claim that:
'HTC marketed the DHD on the basis that it's architecture was such that it didn't need a higher-capacity battery to do its job.'
Well I take it that you assume this on the basis that Leprechauns are real and are roaming New York city as we speak? If HTC were doing any market research at all, they would realize that even devices with smaller screens have a bigger battery than the one they have put into the DhD, including the Desire Z & Desire's batteries?
I remember when I was looking at reviews for the original Desire, as I fancied one, the main complaints were the battery life, and the fact people only got a day's charge on it. So I thought fair do's, big screen, big price to pay? If HTC had done any research, they would have realized that people wanted better battery life, a better quality screen, better sound quality?
You want to know what the real reason is behind HTC putting a small battery inside the Device? Well it's the fact that the entire thing was rushed, and I mean rushed? There's evidence of this in the build quality, the software, the placing of different things within the phone and also the bad batch issues HTC experienced.
The HD was leaked in September/October, it was released by November, this is not normal for any device that becomes 'leaked'. HTC used a bad screen, imported most of the software from the original Desire, obviously making edits to make it Sense 2.0, but you can clearly see they didn't change everything? If you set the Android Pattern Lock Screen, you can see that it doesn't fill the whole screen, the IME is the standard HTC one with some arrows slapped in at the bottom? They didn't even change the size of the keyboard?, this is more evident if you use the IME in landscape mode, its hard.
What sort of company places an Antenna in the Battery Cover? It's true, remove your Battery Cover and you'll loose all signal? Pretty risky move for HTC, seeing as the Battery Cover is VERY easy to 'accidently' break, and frankly your screwed then right? It's like they designed the phone, forgot the Antenna, then quickly though 'Where the f*** is this going?' and decided to place it there? In my opinion, and a few others, they did this with the battery, they made the device too thin, and in reality they just couldn't fit everything in. The Desire S which is slightly thicker, packs a brilliant battery. Problem solved.
The build quality of the phone, is not one of a £500 price tag. Some parts of the phone squeak whereas others just do not feel adequate to the pricing of the device. There again we live in a world where no matter how much you pay, something always seems to be wrong.
Sorry if I have offended any HTC lovers, all attacks on my and opinions against me are welcome, don't get me wrong, I love my phone and I can cope with charging the battery every night. Chao.
I haven't been able to find any threads that already cover this. There are several reviews, users' opinions etc on how long the battery in a particular smartphone lasts, but it's always struck me as odd that this information isn't easy to compare - it could lead to name-and-shame for particularly bad phones or encouraging results for those manufacturers who actually cared & made improvements.
I've found a few people who had the same idea, and one of them (being a much more web-capable person than me) actually made a website for this purpose. I really don't want this to sound like advertising, because the purpose isn't to make anyone any money, but simply to centralise this kind of information and have some (arguably) more meaningful stats driven by and for the benefit of everyone who wants to know.
If you think this could work & be a good idea, please take a look at the site - http://www.wewantbatterylife.com/ . If you think it's a rubbish idea and/or have objections, flame away.
the li-ion batteries normaly have longer life than the old phones...so it will last enough time..u'll probably replace your phone before the battery dies Probably u can ruin it with overclocking your device or something..but draining is something else
ps: im trollling again :O
Hehe, I meant battery life as in "how long does your battery last from a full charge until it runs out?", but yes, mini-troll It's all good..
Hi,
I have another question about batterie life. I don't know if it has been already treated somewhere else in the forum.
I will receive the 2000mha batterie today. What is the best way to calibrate it?
Fully discharge it then full charge or full charge before first use?
Thanks for you help!

my battery in nexus s long about 4 houres in full use , that is problem ?
what can i do ?
Nice site, and it will only grow more useful the more people input their info. Although looking at the results, some of those 30+ hour claims seem outlandish.
my stock galaxy note battery takes me 6 hours to lose 50%. hope it could last longer.
On my Galaxy S running ICS 4.0.4 Dark Knight 2.2, my battery lose about 25% by day. But with light use (1 or 2 calls, some SMS, GMail sync, ...)

my phone keep charged almost 1 day
I don't know if it happen for someone else but i noticed a sort of "bug" with my HTC HD7. (Bought in December 2010)
If i reboot my phone when the charge is at X%, after the reboot, the charge level will be ~10% less than X ... and the phone will stay a very very long time at this percentage.
(For exemple, if after a reboot, i'm at 75%, the battery could stay at this level for all the day)
So as I imagine, it decalibrates the battery level and to make a new time the calibration i have to let my phone fully discharge and fully recharge to solve this bug.
Strange ...
(Sorry for my english guys, I hope i can be understand)
It seems that smartphones need more juice daily. However if you disconnect the mobile packet data whenever you are in range of WLAN you might get 2 days with one charge.
I am actually quite amazed how well my Samsung Galaxy S1 original battery has lasted almost 2 years. When I first started this smartphone journey with my S1 I thought that it will not last one year. I am glad that I was proven wrong.
Batteries
Definetely Smartphones need better batteries, especialy after we got used on some phones to last even 4 days like I had previously Nokia C7, and after that i bought Galaxy S2, and its battery lasts only 1 day, now thats really sad
my sgs+ with a custom rom (gigabread+) is alive up to 24 h.
My I9001 is at 30% at the end of the day (connected to wifi all the time)
battery life xperia s
my xperia s last 3 days with making some calls abou ta half an hour surfing on 3g a day and sometimes a game but when i use it a lot is lasts about one day and a half
HTC HD2 on nand android does ~4-6mah an hour on standbay, depending on torture i give it, it lasts a day to a day and half
My Samsung Note (stock 4.0.3), WiFi on all day, and average use (business mail, whats-app, games, some browsing)
after 15 hours the battery is still 40%~50%
i use SetCPU, it throttles up the CPU if its needed, at idle it runs at 200 MHz instead of 1.4 GHz
My SGS2 can last almost 2 days without using data. Its pretty good on battery
hello everyone, i am new to this community, sorry for my bad english, i would need some help. i have a htc one x for several weeks now, and i have a hudge problem with the battery life on this device, im a really hudge fan of htc, but im dissapointed, so for example, i have 9/10 lines of battery life in my settings menu, i plug it in , and start playing dead space, after 40 mins of playing the battery actually dropped by 2 lines , and i had left 7/10 lines of battery. how is that even possible??! all the phones i had, laptops, etc that require a battery worked in the folowing order: if you plug it in and took the battery out, it still worked, so if you had the battery in, it both keept alive the phone/laptop/every device on the world, while charging the battery, so if you use it, it wont loose power, but gained it. i wached a lot of videos and posts of people explaning hot to get more guice out of htx one x , and some wore like, well , dont use it too much, or do ont turn on your phone to see the clock cause it will save some battery..... ?!?! well i dodn't pay a ton of money to have a phone in my pocket and not be able to see what the time is, or play something/ lisen to music , without actually noticing that in 2-3 hours i wont be able to make a call, yes its a strong phone, and verry good one, by design, by hardware, and software, but the sad thing is the battery, does anyone have a mirracoulous tip for me? and perhaps others as well... (oh and i charged it as ppl from htc told me, first three times with the battery empty for 8 hrs..)
the battery will run out whilst charging, under heavy usage, because the phone is using more power than the charger can provide.
laptop chargers can handle this, simply because the charger provides more power to it. (and the fact laptop batteries tend to be several times the size of the hox)
you should only find that whilst using a battery/cpu intensive task such as navigation (it uses GPS, data sometimes, and the screen is on) that the charger won't be enough, but for most other things, like general web browsing etc, the charger will do it quickly enough
the screen is what takes basically all of the battery, so you can reduce that by making the screen brightness a bit less bright..
the battery life when the screen is off is incredible. WAY better than any other phone i've had. when the screen is off, the phone uses about 1% battery every 2 hours or so. and that was with wifi etc connected and autosync still switched on.
whether the phone will last you all day or not, depends on your usage. if it doesn't, then either make the brightness even lower, or you can purchase a portable charger. or a battery case.
there's no point saying well other phones have better battery life like an iphone. lets be realistic, the iphone DOES NOT have better battery life. it may have had decent standby battery life, but so does tegra 3, probably better than iphone now. when you actually use an iphone, or any other smartphone for that fact, the battery disappears just as quickly as this one does.
Tegra 3 standby is awesome. Just tried an experiment. Please note that this is with 3g or WiFi on all this time and with auto sync.
Again this is just to demonstrate standby time.
For the op, are you sure you don't have a rogue app? Also are you using an HTC charger?

Unlikely. Unless the phone knows it can draw 2 amps, it has to assume a 1A capable charger (designated by connecting the data pins together).

I used it all 11 hours. Mostly reading second book of Game of Thrones in Kindle app. Checked some net sites, xda forum app, some blogs. Few calls and texts. All the time on wifi. Was sick in bed. Auto brightness, but as my eyes didn't liked strong sun is can say that it was quite dim inside.
But it probably depends on usage. Yesterday I was reading on the beach and I had 4 hours screen on time. Probably brightness all the way up as it was quite hot sunny day.
On normal day I get 4-5 hours screen on time.

batteries nowadays can resist pretty much, and unlike a laptop battery that has a chip in it and it records every charge, and then after x charges it suddeny stops working correctely this is cuz of the company chip they insertet to make is useless after x charges, a phone battery is just a normal one, this is tested, i opened a laptop battery and took the chip out, and via com port on pc, i was able to retrive the data storred by the company that produced it, but was not able to reset it, (comsporacy) lol . so i will buy a htc battery, not necesarry one x's and i will test it my charging it a couple o times bowth with the amp maxed, from 1 to 2 (1,1..1,2 etc) and voltage from 5 to 10 V, maby ill get a result, that is a little better than the technique i saw a couple pages away about charging your phone, then powerring it off, charging it again, then pwr on charging it again etc, forgot the method name, but in my opinion bubjecting a rechargable battery to so manny fluctuations of current in so little time does not sound good, my idea of amping the charger or the voltage by just a little sounds a little better in my opinion

you have a lot to learn then.. Batteries can explode, and they do: here's a video of some guys iphone setting on fire in his back pocket, turned out to be the battery that caused it.
http://www.youtube.com/watch?v=AIRXDeEzlcw&feature=youtube_gdata_player
That isn't my pure reasoning behind my thoughts anyways, whatever experiments you do with higher amp chargers won't do anything, because the phone won't accept more charge than the circuitry allows. Which happens to be a safe amount for the battery. This is so the battery doesn't get damaged, and in some circumstances, set on fire or explode.
If you take the battery out and start prodding things at it and take it over its limits, be prepared for fire or explosion. Like Ben said, put yourself and only yourself at risk if you choose to do it.. And be wise and have a fire extinguisher ready.

hello everyone, i am new to this community, sorry for my bad english, i would need some help. i have a htc one x for several weeks now, and i have a hudge problem with the battery life on this device, im a really hudge fan of htc, but im dissapointed, so for example, i have 9/10 lines of battery life in my settings menu, i plug it in , and start playing dead space, after 40 mins of playing the battery actually dropped by 2 lines , and i had left 7/10 lines of battery. how is that even possible??! all the phones i had, laptops, etc that require a battery worked in the folowing order: if you plug it in and took the battery out, it still worked, so if you had the battery in, it both keept alive the phone/laptop/every device on the world, while charging the battery, so if you use it, it wont loose power, but gained it. i wached a lot of videos and posts of people explaning hot to get more guice out of htx one x , and some wore like, well , dont use it too much, or do ont turn on your phone to see the clock cause it will save some battery..... ?!?! well i dodn't pay a ton of money to have a phone in my pocket and not be able to see what the time is, or play something/ lisen to music , without actually noticing that in 2-3 hours i wont be able to make a call, yes its a strong phone, and verry good one, by design, by hardware, and software, but the sad thing is the battery, does anyone have a mirracoulous tip for me? and perhaps others as well... (oh and i charged it as ppl from htc told me, first three times with the battery empty for 8 hrs..)

I've been having the same issue as well. The stock ROM on HTC one X drains the battery rapidly. For me, In normal day which includes listening to music, playing games, browsing and making calls, my battery would last maximum up to 20 hours; meaning that every night when I go to bed I had to charge it for the next day.
This problem was battling me a lot. I learned that the stock ROM is taking advantage of all (4) CPU's and memory even while in idle. The whole battery consumption relies on the CPU usage and Memory management.
I moved to a custom ROM called ViperX 2.6.0. I'm very satisfied with the result. It seams that they've managed the CPU and memory in a very good and neat way. The ROM has a lot of tweaks.By default, when installing the fresh ROM and wiping the battery stat, the battery would last one and half a day. By doing a number of simple tweaks such as disabling the animations on transitions, disable fast dormancy and disable smart sync you can have the battery up to two days.
Check the attachment, it's a screen shot of my battery usage.
Hope this helps.

How the hell are you getting this much screen time ?!
I dim the screen to the lowest brightness and disable
sync and sometimes in flight mode, and I can hardly get
3h of screen time! I mostly read on it, so it shouldn't
be battery intensive.
oh, and If I use it outside it lasts even less 2-2.5h.
What's your secret?
Oh and I use the latest CM10, and downclock my
cpu to 800-1000mhz

Then your phone is knackered.
I can get 4+hrs screen on time with auto brightness, auto sync, stock cpu levels with wifi on.
That's no secret, that's just what it does.
As for 'just reading' - you can easily get over 13hrs screen on time with lowest brightness & flight mode - I've tested it myself on the Kindle app.

AOSP roms get much less battery life than Sense roms, 3hrs screen on time is about average.
I'm currently running CM10 with Neo kernel 7.2 @ 1.3GHz and getting almost 4hrs screen on time. With Faux kernel it was usually around 3hrs.
Chrisjcks, what do u mean by "your phone is knackered"?!
Its a new phone! I just got it 2 weeks ago.
Michealtbh, it may be somthing with the APOP rom, but I really
hate using sense ... I want to try this Neo Karnel first,
Can I just flash it on my cm10? (without wipe)
Where can I get it?
How do I know which kernel is im my current rom?

Your phone is fine.
You can find it here http://forum.xda-developers.com/showthread.php?t=1873615
You have to flash the boot.img through fastboot then the modules in recovery. You're probably using CM10 kernel atm

Ok, but don't moan of battery if you are running a beta (alpha) custom rom.
The HTC ONE X battery is fine, especially after the sense 4.1/4.0.4 upgrade from 2.17

Michealtbh, Thanks!
I'll try that soon. (it's stable, right?)
I'm now testing the new Nightly.. it's real good and battery life,
seems promising, looks like I'll get 3.5-4h of screen time there
(No sync with low brightness though)
chrisjcks, I'm not using alpha roms, just the stable ones.
and this DOES feel very bad battery life to me, I come to the hox
from Motorola milestone, and there I could easily get 7-8 hours
of screen time with wifi. (and it has smaller battery and 40% overclocked!!)
How much do you get on the new stock?
When I was on stock i remember it ran out after half a day,
only using it for music and taking some videos.
Battery life varies a lot. On stock in London I get a full day screen time of around 2-3 hours with 3G on all the time. Which for me is fine.
Last weekend I was in Portsmouth and the signal was very patchy and my phone died within 10 hours. Hardly any screen on time.
So it does really depend and will vary for user to user depending on your signal and how the phone is set up.
Mine is usually on auto brightness, and auto syncing on.
Today I've been at home as I've got a damn cold but my screen on time is over 4 hours in good signal and wifi. Same setup. So you can gather from this that signal, data used, etc can affect battery life in many ways.
