[Q] Desire HD battery life question before I buy

Hi,
I'm planning on buying a Desire HD, but just curious about battery life before I lay down a grand on it.
At the moment I have an HTC Hero, when they were in their heyday many people complained about the short life on them. I can get 2 days out of mine, with syncing over wifi enabled the whole time. I put the complaints down to people with background apps sucking CPU or too much twitter/facebook/whatever crap syncing as well.
Now most of the reports of poor Desire HD battery I life are from people on their first charge (who clearly don't understand the characteristics of Li-ion batteries), people who expect to be able to thrash the phone all day with the screen on without it dying and generally people who just don't sound like they know what they're talking about.
I know there are two bugs which peg the CPU at 100%, the one fixed by having debugging on and the calendar bug, which sounds like it can be fixed by clearing calendar data or leaving syncing off. I think these were affecting some of the people who were complaining about the short battery life.
So my question for Desire HD owners is, can you last at least 6 am till 10 pm with a bit of use (something like 10 min browsing, 20 min IM, email syncing all day, 1 hr music, 20 min calls) without it dying? Currently my Hero does this fine and a full day without a charge is a requirement for me.
Thanks.

Yes, if you set it up correctly. From your post it sounds like you know what your doing when setting it up.

Before i tried the battery calibration i was getting from 8am to 9pm with moderate usage. TBH i was put off by using it as I thought it would just die on me too soon.
After the calibration (search forum for it) i got from 8am to 4pm the following day where the 15% warning hit. So do the calibration and you'll be as happy as i now am with it. I never got my iPhone 4 to last that long!

Thanks for the info guys, exactly what I wanted to hear!

I haven't taken any precautions to save battery life and I am getting 25-26 hours on a full charge...and now having had the phone for 2-3 weeks it seems to be getting even better!! I've been getting 36 hours out of a full charge these past 3 days.
I do not turn wifi off. I have screen brightness on auto. Syncing lots of stuff hourly (even weather!). I use 3g when I go out but this is about 2-3 hours tops on week days cause I have wifi everywhere i go. battery life has never been an issue for me and I use my phone frequently...play games for 20-30 mins. watch videos via. skynews, listen to some music etc. etc.
As for the bugs...I do not have usb debugging turned on and I have never had the /INIT problem...perhaps it was fixed in the last update? and the calender bug...never had that problem either and I use my calander with google calander, facebook, holidays and person agenda.

I think you'll easily last a day with the usage you mention. As a rule, I think you normally get up to 4 hours display on usage off a charge (browsing, messaging, watching vids etc).
I'm travelling from Ireland to NZ on Monday, which will equate to 36 hours travelling with probably no access to a charge, and lots of time spent sitting around using my dhd. There's no way the phone will last right through, so have bought a 5000mAh USB battery pack for £20.

I'm currently at 22 hours and still at 42%.

I get 2 to 4 hours depending on useage from full charge. 8 - 9 hours if left on standby and not used for anything.

Well...I think I have had similar results....
flash one of the custom roms, with one of the OCUV kernels and setting max. speed to one of the UV speeds (mine is set to 1.1 Ghz which is UV 50mV), also setup useful profiles in Setcpu (I have set screen-off to use max 384 mhz - which does cause a 1-3 sec lag when screen is on again) and <20% battery etc...
of course, if you play heavily with your dhd you will not get these results, so you can put wifi on with this , but need to think of what you want to do, because using your DHD for 2 days, does require limited screen usage (imho, this uses a lot of battery)

8-9 hours on standby???????????
even 2-4 hours whilst using it is terrible!!! When I got my HD and unpacked it I didn't put it down after a full charge and I got 8 and a half hours with non-stop heavy use.
I think you have a faulty battery!!

I too moved from a Hero to a DHD and I can say that with similar usage, the DHD loses to the Hero by a decent margin..maybe u might get a couple of hours less of usage compared to the Hero but the difference isn't very drastic
Moreover on the Hero I'm using CM6.1 Froyo overclocked and the DHD is on Sense, so logically speaking the Hero should get slightly better battery life on CM6.1 compared to Sense. I'm sure after rooting and flashing CM6.1 and undervolting/underclock the DHD, i'd get better battery life because the DHD is like much much faster than the Hero, so I'm sure even if i underclock it, it'll still be super fast.

The battery is 'fine' i'm using current widget to track and its performing to around 1100 mah which is not too far below spec. The problem is the current draw. In use i'm drawing 500 to 800 mA and in standby around 80 to 300 mA. These figures are consistent with the battery life I'm seeing and the battery working close to spec (1230mAh i think?)
There are lots of bundled apps like Maps running all the time in standby drawing current and I haven't yet figured out how to stop them. Stopping them with task manager just sees them restart with even bigger current draw.

Something is definitely wrong (as I'm sure you're aware) with only 9 hours on standby.
Out of interest, remove ALL widgets and see what difference it makes. Also, give us an example of what processes are running?
I would get rid of all task killers and also anything monitoring your system. Those themselves can draw more than you think.

wow well I'm no battery expert but it really sounds like something is not right there. I don't have any battery drain from apps in standby and I do use maps.
I got 1 day and 16 hours from a full charge today (just put it back on charge now).
Thats with wifi on for 31 hours (always on, doesnt sleep when the screen locks), 1 hour and 24 mins of talk time and the screen on for 4 hours and 5 mins.

thats definitely wrong somehow.. should never drain that much, perhaps it is because you let currentwidget drain it all the time
(na dont know why it is like that but it definitely is way too high)

official firmware, medium screen brightness, default sync widgets
heavy use: 12-15 hours
light use: 24 to 36 hours
this is how its been for me ever since the battery calibrated, needs around a week or use the battery calibration trick

I too have just moved from a Hero (running VillainRom 12) to the DHD (stock Sense over FroYo) and even though I have only had it a week, the battery easily lasts a whole day with the moderate use you describe. Unless I get stuck into a session of " Angry Birds ", which seems to kill the battery pretty fast. But ABs had the same affect on my Hero. Constant screen time on that beautiful 4.3" display sucks the battery. I find the same thing when using the DHD as an in-car gps. The warmth of the back of the case is testament to how much energy has been expended. So I connect to the car charger now. I have also bought a portable backup battery (plugs into the microUSB) just in case.
I don't regret spending NZD1000 on the DHD. My son is looking forward to inheriting the Hero.

Well I charged it up overnight when I got it, my first full day was today and I got 7 am till 8:30 pm using it almost constantly (quiet day at work). I don't know how people can run them flat a day with normal use. And I know it'll improve a lot after a few charge cycles.
It doesn't look like it's going to be much worse than my Hero.

Thanks for all the advice. I uninstalled all widgets and it improved a little. But still things like maps/maps sync were constantly burning juice and no way of stopping them running.
I installed Launcher Pro and can report that my battery life has approximately doubled. Typically i was getting 4 - 6 hrs use and sometimes only 2 (light use). Now getting between 8 and 12 hours of fairly heavy use. Its still not up to some of the figures others are reporting but Launcher Pro has helped a lot as all those constantly running apps that were draining my battery just dont start themselves up any more!

My - Battery Sucks -

I have to charge it twice a day, and my use is for only couple of hours talking and few browsing.
I tried that with stock as well as
[ROM] cwm-Phantom-X-
is anyone else also experiencing the same?

a few hours being like 10 hours straight talking?

You're crazy. This battery is the best I've seen in a long time.

im getting 12 hours with normal use and 8-9hours with very very heavy use(basically on my phone all day non stop)

I can drain a battery in 6 hours or less. I can't make it through a 8 hour work day without charging it. I guess you guys that go 12+ hours on a charge aren't power users. I tried every rom and kernel and my results are exactly the same.

Maybe the people who are complaining about battery life came from a flip phone or a blackberry. As far as smartphones go, this is the best you'll find for the features and enormous screen we have. Don't believe me then get an Amaze, Sensation, myTouch 4g Slide or G2x.

I did the battery wipe with full charge, if that makes any difference.

I dont know bout anyone else... but the only battery problems ive experienced is the fact that ive become so damn lazy on keeping the phone charged.
The battery lasts so long that i forget to charge it, and then i run out of battery

I'm a heavy user literally all I do is watch 1080p movies and plays games on my phone. I get twelve to fourteen hours every day. I also get at least a text every fifteen minutes if not more. Maybe the developers didn't remove career ciq which bogs down performance and drain the battery. You can also try a different kernel.

don't forget that in areas where you have crappy signal, you phone pumps up the power to try and compensate. you may notice your phone heating up in your pocket too. If you have no signal at all, i weep for your battery life.
go into airplane mode to save juice.

I too get 24 hours or more from light to moderate use with juggernaut.
Heavy use still nets me at least 10 hours. Although I toggle things off if I remember and don't need them. Like wifi, data, auto bright, sync, etc. although WAY lead important with this phone than it was with vibrant running cm7.

I had some weird battery drain with the stock rom. I couldnt get more than 5 hrs with light usage or heavy usage. I flashed streamlined (a mostly stock rom) from teshxx and im back to having 9-10hrs of battery life with moderate to heavy usage (3hrs of on screen time)

Why don't you try adding another core to your G2 and see if you can even get 6+ hours!!!
Cmon man, this is a dual core phone...it's just common sense that it will use twice as much battery power to get it to run smoothly.
But honestly, I was able to get 21hrs out of a full charge. With heavy use but i had it UC'd @ 1.2max and 192min. Still ran pretty smooth tho.

I get about 18 to 20 hours from a full charge. Stock. Non-rooted, and no modifications of any kind. I have all my apps auto-sync every 4 hours, and my usual display "on time" is around 4 to 5 hours. Here are some screen shots. This is the best battery life I ever had.

Just to add. My brightness is at 40%

is it better to use autobrightness on our device or a set brightness setting to save battery?

I'd say set it to certain level. Having the phone constantly adjust I would think would use more battery.

[DISCUSSION] Xperia S battery life

Had my beautiful white S for 24 hours now. Overall very positive, except battery life so far. Drained 23 % overnight from a 100% charge. In only 7 hours I had NO activity. BT and WiFi on.
I hope this will improve very soon. That is a no go. Would like to hear from you about your experience regarding your new Xperia S.

For me, I removed junk I don't use, like foursquare. That alone made a huge difference. I also turn off data at night, and only went down about 4% while I slept.
Another option is to install something like JuiceDefender, which automatically shuts down data except switching it on every hour or so to allow for some syncs, then shuts it down again.

same as my arc, drained about 30% in the first day, with time it'll be better.

i was about to ask the same question. 7 hours seems about right, but i have been doing a lot of app installs, so I will give it time to settle down.

I use the XS in Hong Kong. If I use the phone online to play with internet browser, battery will be drained from 100% to 69% in approx. 1 hour. Is it too fast? Or it just a normal way when compare with SII or GN?

The display sucks battery life like a vampire in a young virgin woman buffet. Try reducing the brightness.
Hopefully firmware updates will help there.

Ohh yes. U are soo right. Had my phone now for 4 days. The display uses an average of 70% of the overall battery consumption. It is not WiFi, calls, BT or any other functions. It is the display that drains. Will give it the weekend to see if it improves. If not I will return it on Monday :-( And my brightness is down on less than 25% so not much to do there.

I get about the same on my Arc. I dont know if it's too fast or not, but if your pretty much constant on the net for an hour say then 69% isn't all that bad.

Had an Arc for around one year. On a daily average the screen took about 55% and I had no problems to get a full day out of it. (approx 16 to 18 hours) and still 10-15% juice left. Now I get max 10-12 hours out of my S and NO juice left. Really disappointing. Even my old X10 did better than my new S.

Surely the HD display amongst other things, ie how you have your phone set up, may go someway to why your experiencing poor battery life compared to your Arc.

Try to disable Bravia engine and see if you notice any difference especially during the night.

My phone has the same apps as my Arc, actually minus few of them.
No autosync etc.
Basically it drains the battery quick, it's unacceptable. It behaves exactly like one of the older Arc firmwares, which was also draining battery like crazy.
Than they fixed it and it's still brilliant. My Arc on Flight Mode beeing just a backup in case of any problems, runs 3rd day on one charge, still 75% left.
I think S is just not optimized and it makes me mad.

Just got My XS yesterday I did one fully charge this morning . Turned off data at home, will not know until battery is fully charged by a few cycles. I love the phone irrespective of the flaws. I think may be see in a week or 2 where my battery settles.

Again. 25% battery drain in only 6 hours over night. No physical activity at all. This baby goes back on Monday :-(

3g turn on with weather widget in background only, 4% drain overnight, but with heavy usage (game, internet suffering...) it lasts about 7 hours, that's good.

You can use Profile Scheduler (free from market) and set a schedule.
I've set the schedule in which the airplane mode will be activated at 12.00 am and turned back to normal at 6.00 am.
By this way, my phone battery drains overnight just only 2-4%.
Let's try man

I actually agree with that tbh, and another thing is battery life all depends on how the individual uses their phone.
I had the sgs2 and alot of people said oh the battery life is rubbish but yet they had:
screen brightness on 100%
3g, wi-fi, bluetooth always on
live wallpapers running.
Plus they were using the internet for like 2hours
sending numerous emails
playing games
listening to music
I mean come on its a phone at the end of the day, its not a super computer or something or some nuclear powered device.
I nearly 2 days out of my sgs2 under moderate - quite heavy usage
because I turned my screen brightness all the way down
didnt leave 3g, wi-fi, bluetooth on all the time only when i needed to use those features, i never used live wallpapers and i dont send numerous emails.
when i had the play again people said the battery life was rubbish but again i got about 1day 10hours or a bit more sometimes based on the above mentioned info.
so as long as my SXS last 1day even I dont mind that because at the end of the day it has a HD screen so its going to use alot of power.

Okay so on my third day with the phone...
my battery is fine, actually...more than fine. I turn off my wi-fi/bluetooth/gps when not needed, and I don't run my battery heavy apps for a long time.
I also installed a task killer...I know it's in theory not needed, but I will see how it goes.
woke up around 7 today, used my wifi, used a battery intensive app (dream zoo , it's an addiction) for like 15min or so. Went for a walk, used the camera...a LOT, made a lot of panorama pictures. It's now almost 11:15 and i'm only down less than 15% I believe.
It's got much better battery usage than my X10 to be honest...but this is a high-end full HD phone, I wasn't expecting my battery to last so well D:
I will update again at the end of the day about how low it got, but I am pleased with it.

Batt life varies from device to device ? Or charge and cycling

Last week I made thread on How phenomenal the batt life was for the hox..Now with my secondary line and 2nd hox I retract the statements
Or maybe someone can help or justify that theese sealed batteries do get better with charges
Got a mint...used white hox rooted stock rom
Last week Battery life was phenomenal 15 hours heavy usage 60% life left at 9 pm. From 6am to 9pm
Gave it to wife got me a new out of the ... BOx 2nd hox
Not rooted stock Rom.
After 5 hours medium use 7 am.to 12noon I'm at 57%
Now this is why I ask my question ..not sure what the gentleman did to the white one x I got Used. But it had way better life and he got it on may6th new from a preorder.
Could it be was a better unit or did batt life get better over time and charging .
I'm pissed the white one...is... better
But my silver doesn't have screen glitch or bleed through or any of the know... Issues
The white one did have screen glitch that's all

The battery drain with a out of box device was horrible (Just my opinion and experience)
Just let the phone settle for a week, u will find a lot of change in the battery drain.
Right now there is no difference in drain in between a rooted and non rooted device.

Charging and cycling has no effect on battery life.
Sent from my Galaxy Nexus using xda premium

15 hours heavy usage with 60% left? Heavy usage would kill any normal one x in half that time, so it depends on what you define as heavy.
If you can show me screenshots of 15 hours on battery, 10+ hours (even 5 hours!) screen on time and 60% battery left, I'll believe you.

Hyperion battery under-performing?

Got the Hyperion last week from Amazon and overall I was impressed with its initial performance. It was a huge boost from the oem battery as I didn't have to recharge my phone at all during the day.
My only concern is that I've noticed I haven't been seeing similar numbers as others have mentioned with their Hyperion. I mean, I'm not getting 24+ hrs of use with 8 hrs of on screen time. I'll take a photo next time when its at its lowest charge but I am averaging about 5-6 hrs of on screen time, and thats with basic use, surfing the web, texting, couple phone calls, no games or movies, wifi/gps/sync on, and 30% brightness, non rooted as well.
Does anyone else feel their Hyperion isn't performing as others have claimed?

24+ hours with 8+ hours screen is is down right impossible. The reason people get extended batteries is because they want more than the stocks screen time for 4-5 hours without worrying about their phone dying.

Not really... With the correct kernel and ROM I can push that if not surpass it. Paranoid 2.51 leankernel 1.6 been home all day from the storm... That's 3 hours 12 mins screen on time @ 67% juice left.

For me, not so much. Today for an example, I got a little over 12 hrs until I hit the 5% mark with almost 6 hours of screen on time. Home all day too with wifi on and screen brightness at 30%.
One thing I did notice though is that the "sdcard" used 1 hr and 17 mins of the battery. I've never even seen the sdcard on the activity list before, this is the 2nd time I've seen it since installing the Hyperion battery. Hmm what could it be?

I almost made it.. I'm running Aokp build 4. Not sure what the kernel is.
Plus the batteries have to go through a charging period... I noticed the first day it lasted a long time almost 2 days. (1day22hrs)I forget what the screen on time.

Have you looked at any wakelocks your getting with better battery stats? That is pretty bad for the 4200 batt. Did you do the charging cycles that were detailed in the user manual?

Hey I was just passing by and reading threads, although I don't have this battery, a very possible reason that your battery life might not be as good is that you're still on stock. Notice everyone else who posted is on a custom rom + kernel. The GS3 stock roms are nice but come very bloated with apps. I read somewhere that on stock when you start up your phone, by default it starts a very impressively high number of processes ~50ish. I could be wrong on that but yeah a bloated stock rom MIGHT be the problem. Just my thought.

No I have not tried that app yet.
And yes I did follow the initial charging instructions as well.
It has to be something with the phone because even with the stock battery I had terrible performance, it'd last me only 3 hrs of on screen time where I've heard most users receive around 5.
He is my cpu time, it seems normal since the phone is spent most of its time in deep sleep.

Good at first/No so good after a couple months?
I havce the Hyperion, and have experienced close to 48 hours of life, albeit with very little use. With moderate use, I've experienced 30 hours. My screen time never surpasses 3 hours per day.
A few weeks ago I installed the Serenity 1.1 ROM. I have not been able to get more than 15 hours with that ROM.
This morning, I put in my stock battery, and it has been in for 9 hours so far, and is currently at 83%. I did a reboot about 4 hours ago, so don't have accurate screen-on stats. But I'm never at 83% this time of day with the Hyperion.
ANyone else experience good, then later, poor performance from this battery?

In the beginning I head awesome battery power. Now the battery is horrible I only get 2 hours screen time at 65 percent. Any ideas? Also undervolted and running 1.8mhz but battery still runs hot.
