Battery life

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

[Q] HTC Desire vs. Desire HD Battery Life.

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?

I forgot to mention, all the time quotes are when the phone reaches 30%. You can actually get more out of it if you push it further.

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.

Someone Swyped my idea.

Near 2 months of using DHD. Battery life is improving.

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.

Htc One X -battery life

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?

i know stand by is awseome, and i am using the original out of the box charger and cable, but i might go ahead since i know a thing or two about electronics and modify the charger at 2 amps vs 1 amp currently.. this will give me faster charging, but im still researching, cuz i have second toughts
p.s. do you have a costum rom? it doesent look like a prtscreen from htc one x

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).

dude calm down ) lol im a student at mechatronics and robotics, i make robots, and work with voltages and intensity, yeah, normally i don't tweak this kind of things, but a battery does not cach on fire or explode, ony batteries from cars and up, not small ones the worst that could happend is it will heat up, and if let alone, will pour battery acid, wich is not dangerous like car acid , cuz is in a verry small amount and it just needs not to be handled by unprotected hand.
p.s. since im new, cant post alot.....

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.
Full stock One X.

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 scare the **** out of me. Please don't do this indoors or near any other living creature. You know nothing about charging batteries and are going set your lithium ion battery on fire.
Go check out http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries before you hurt yourself.

dude calm down ) lol im a student at mechatronics and robotics, i make robots, and work with voltages and intensity, yeah, normally i don't tweak this kind of things, but a battery does not cach on fire or explode, ony batteries from cars and up, not small ones the worst that could happend is it will heat up, and if let alone, will pour battery acid, wich is not dangerous like car acid , cuz is in a verry small amount and it just needs not to be handled by unprotected hand.

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.

Battery life on ViperX 2.6.0
nutzaalex said:
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.

Battery life

I was just wondering how long people were getting out there battery life? my phone really varies, I can get just about a day with moderate use with music and browsing and phone calls but any more such as games and only get a few hours, I've read people get 2 days sometimes out there's and I've tried the power manager with smart only and battery saving apps and still no luck, It does annoy me sometimes when people say they can get days out of it, Any recommendations? I have been on b106, b111 and b119

I usually get about 4 days of use. This is my secondary phone so I don't use it as much as possible, but on days that it gets his share of use, the battery last about 2 days. So let's say that the average is 3 days.

I'm running Stock B122
Usually get a full day when I use the phone a lot, and 2 days when it's mostly on standby.
(for me this is slightly better than b119).
I have now underclocked my CPUs to 1GHz (I don't really need 1.5), and will see if it makes a difference to the battery life.
Antutu score for CPU at 1.2GHz is close to full, but for CPU at 1GHz, the score is about 3/4 full CPU speed. I figure the performance is OK, so if the battery lasts longer, then great.
Edit: Returned CPUs to 1.2GHz - performance OK, and battery slightly longer (2 days with my normal usage instead of 1.5 days)

The graphs in NoFrills Cpu-control shows that it doesnt go even close to 1,5 ghz. - 75% of the time it is at 1 ghz, the other 25% are below that - mostly at 200 mhz. But it was for the last 5 seconds i think... I will try kernel tuner, i think it showed the graphs for a longer period.
Btw: thinking and observing my battery stats, do you guys think that poor reception is still draining battery with modern phones ? In my living room i am constantly loosing signal or being max at 1 bar and I think that's sucking up my battery a lot. Any observations on that ?

Regarding the battery drain, my observation are same. On my work I had bad signal and battery is go down faster than when I'm on my home and when I have good reception of mobile network.

True. Did notice quite early. Bad reception drains battery quickly.
And im not sure if its normal (because of i haven't compared with other mobiles), the wifi reception is not as good as the galaxy tablet im using. When the wifi reception is like 1 or two bars, on the galaxy tablet the wifi gets picked up and remain stable. While from the same location on the P6, it is quite unstable and keeps going on and off which is a battery drainer, and yes i did not activate any of the advanced wifi settings.

I thonk its a little bit better now with B118, but sadly a lot of people loose/have poor reception in our living rom.

Same thing for me... When I stay in poor reception zones, battery's drain is higher... Is similar when travelling, the phone "handshakes" in more constant way with different net antennas and this wastes the battery life...
That's happen also with older phones (not smartphones) but the ratio features to battery size is better in these "old phones", with less battery drain than today's "smartphones".
Best regards.

BTW: At your advice, what's good and specific app to compare battery life between different ROM..?. Until now I've used a very simple way of doing so... And this is not exact to compare in a meaningful way.

Also when out of signal it is constantly scanning for network. But the logic behind low signal... maybe 1 bar means on and off, which is also with scanning. Or the modem is "overclocked" to maintain that signal. Who knows what is inside it's brain
The only thing I trust is myself using the phone the same way I always do for a couple of days.

I think that's similar to the FM digital radios, below a certain signal level (trigger level) needed to improve signal to noise ratio for optimum reception, it scans continuously, searching one adequate level signal.
In fact, our smarphones are, only, a tremendously sophisticated and powerful radio transceivers and they need a good signal level for work well...
And they search steadily until find it... Of course, our batteries pay with her life

Until now I've used a very simple measure system... After have 100% charged, took the phone, stops all services (except calls, also screen is off) and wait to reach 10% of battery... But is not much technical way to do so...

[Q] Need a help on a new phone.

Hi Guys!
I'm currently looking for a new phone. I can only buy midrange phones atm and since the G4 and S6 are released, I expect both of their predecessor's price will go lower. Apparently, I'm torn between the previous flagships, G3 and S5, which is still of course still capable now. I really like the G3 over the s5 but I am bothered by the battery life that most people say is bad. I mostly need the phone to school at around 12 hrs off the charger. At school I usually just text and call a few times, take pictures and notes, occasional time wasting games on breaks and also I listen to music on trips to and from school [approx 1.5 hrs of music]. My question is, will the G3's battery be capable of that amount of usage? Or will I benefit on the S5 on this? Thanks in Advance!

That's very similar to my daily usage pattern and my G3 never died on me. You can expect between 4-5h of screen on time. It really depends on your signal, if you live in a poor signal area, any phone will take a hit in battery life.
The majority of people who complain about G3's battery life came from a G2 or similar phones, and they're used to getting 6+ h of screen on time. For them, it was a downgrade in the battery department.

Now I'm starting to get really excited to get this phone more, well, another question, are there any major gripes on this phone? Also coming from an old phone with a really mediocre battery life (Xperia Sola), I think the battery life of this is definitely enough. Based on what I read before, It's mostly the battery, but as you said, based on my usage, I would get throughout the day easily, so the batteries are crossed out. Any other major thing (flaw?) you would say?

It's all relevant, some things that annoy some people might not be an issue for others, and vice versa.
For me, there are 2 things i don't like about the G3, but they are not that big of a deal, i can live with them. The first is i would've liked if the display can get a bit brighter (especially on very sunny days). The second, coming from the last 4 generations of nexus devices, i miss the software fluidity of stock android, despite that i appreciate some of the feature additions LG has thrown in their "skin".
All in all, i would take the G3 over the Galaxy S5 anytime.

Ok, I went to a local LG store in my place and played on the LG G3 a bit. The G4 was there, and I'm drooling over it, the leather back was so nice. Ok ok back to my question. After using it for a few minutes, I noticed the brightness to be low and I checked it, it was at 90%. My problem is as I am trying to increase it, there's a warning shown that the temp was high so I can't increase it more. My question is, does it happen often? The overheating?

As an LG G 3 power user I can confirm that the phone will indeed heat up from time to time, however, the phone you played with was most likely plugged in to a charger from what I can read.
Any phone that's being charged up and used at the same time will get hot, it simply puts more strain on the battery.
You should be able to get the 12 hours you need out of your device on a full charge, especially with the power save g to that come with it, however don't expect do go a full day (24hrs) without it having to hit the cradle.
I hope this helps.

Indeed it was plugged. So I guess it is indeed because of that. It's ok for me if I need to charge it everyday, as long as it can last for 12 hrs. Thanks!

You can expect much much much better battery life with G3 or S5 than your soon-to-be-ex-phone Xperia Sola.
Both G3 and S5 almost the same battery life, even though G3 is better in standby time.
If you buy G3, immediately update it to latest version. Your phone will not overheat ever, like mine never did
Only hard gaming for a 1hr+ time can make it overheat.

Well...Depends. I don't think it'll last for 12 hours. You get 5hours of SOT only on the lowest brightness setting, higher the brightness lower the SOT. For me in school it lasts for 8 hours max, then gotta charge it. Also it's true I'm using it most of the time for 4G so that may be why.

I really think it's battery life would be enough, as what you all said, also since I can manage to use my sola for that amount of time which has a ridiculously short battery life. Hahaha! XD. Also thanks for the info! I'll definitely update it, to get a taste of the lollipop's sweetness.

I only use 3g (H+ is enough for me), so definitely/ probably I can get it pass that 12 hr mark. Signal was a bit of a problem though at school, since the school is near a jail, they seem to have network jammers installed. Weird.
