I have been reading of a lot of threads about how to save battery life..
here's what I done:
1. gps off
2. auto kill w/ advanced task killer
3. screen brightness at low
4. sleep screen after 15 seconds
I have got my desire for a few months and battery life has been bugging me. I understand that modern big touchscreen will drain the battery as compared to normal phones. Using a custom rooted rom atm.
I unplugged the phone at 12:00 with data on (push, auto-sync, etc), when i woke up at 7:00, I'm getting 73% of battery life. Charged it to full again and unplugged it at 8:30. My phone the phone shutdown by itself at 21:30. It's a little bit more than 13 hours of battery.
Is it me or everyone else is getting the same number? I just installed setcpu and see how it goes.. please tell me if there's any other way to preserve more battery!
I think it partly depends on which ROM you are using. I am currently using a new ROM (which I LOVE) but I've noticed that my battery life has decreased quite a bit. It can be kind of a trade off. I love the ROM so much that I'm not going to change it but it works ok for me because most of the time, I am somewhere where I can charge my phone if necessary.
Just found this thread which might help. http://forum.xda-developers.com/showthread.php?t=755903&highlight=battery+usage I'm going to try it and see if it helps.
- ROM?
- Display on time?
- Cell/WiFi on time?
- Chrome2Phone (or similar) running?
- Any battery widgets running?
- Any social networking apps/widgets running?

..overall the battery lifetime is not as good as we would like it - but its a general smart phone problem - anyway I charge my device once per day...who cares?

Do you think it might be android notifier? it's set to send every event..
What's the average battery life with cellular data on?
My battery life is also quite shocking, also lasts for approximatly 13 hours under normal use, but if it is in standby then I'd say it lasts for 20 hours.
under normal use:
no 3/2g mode, just wifi
leedroid 2.2a
occasional games
occasional call (like 1 in 10 hours)
1~2 messages
btw you can find display on time in 設定->關於手機->電池->喚醒時間

np
and your current battery status?
(sorry I type faster in Eng XD been away from TW for like 9 years now...wanna go back TT)
Do a full typical usage discharge from full to near off and see what the battery stats in that section read for Display, Cell, Phone idle and anything other (tap each one for hours and percentage).

I'm not familiar with the app but I am with FB and such and their widgets. Any app/widget polling at high frequencies like per second or per minute produces a high additional average drain which cuts runtimes, especially standby efficiency. That includes monitoring apps.
Do you have the battery widget chosen in Extended Controls, or the auto-brightness?

I can't say because supposedly, mine is well above average. It depends critically on usage and setup, too. 24-42hours with 5-9h display on and WiFi/2G always on is quite the norm on mine. Put to sleep (standby), it doesn't drop 1% until 6-9 hours. There's many many threads every week about this now. And I have many updating widgets and auto syncs running, just nothing to do with social networking since I've completely deleted from my phone.

Sorta new to the forum.
Just got me a HTC Desire. Rooted running CM6.0.2
If i baby it, i get maybe 6am-2pm. Heavy use, its done before noon. Ouch
Standby is ok, i left it off the charger last night and I lost 25% over 10.5hrs.
Ive got 1 twitter app on a 5min refresh. Weather is on 1hr. Screeen is down around 15% brightness. setcpu is on 245min, 998max, scaling on demand an a screen off profile of 245.
I have no idea what more I can do to get more then half a day out of it without just not using it lol.
Im pretty new to Android and all this rooting/rom stuff so maybe Ive got something screwy. I also tried a second battery from a friend, no change.
set that friends widget to longer than 5 mins and the weather widget to every 3 or 6 hours. i bet you that will get you alot more time.
Made the switch but cant see it making that much of a change.
Any other suggestions?
How long your Z battery last?
I do not, and never, have any custom ROM on it. It is unrooted.
I have only 1 Gmail, 1 yahoo mail, 1 Exchange, 1 Facebook, 1 Twitter, ebuddy, whatsapp... disabled HTC sense and stocks update. News and Weather updates every 12hours.
But over 6hours sleep with me, I lost almost 40% of the battery.. ..
I do not install any Task manager, the DATA is not always on. WiFi will be switched off while screen off.
I have Exchanged Sync every 15mins. nothing else.
I am wondering shall I buy a new battery or ask HTC to check the Z.. . .
I had a similar problem .
my problem was since i don't get strong 3G signal at my flat,my phone
would keep switching between 3G and 2G ,i used to lose %50 charge while i was
sleep but now i keep my phone on 2G only when i am at home. it has solved my problem. obviously you might have a different problem though
I have a similar experience. The first two months I had a different carrier with less "coverage" in my area. Now I have a different carrier with a lot more coverage in my area. I've noticed a 10%~20% increase in battery life with the same usage. Maybe it is because the battery is just now getting up to his full potential but I think it has a lot to do with the coverage of the carrier.

Try calibrating your battery first. It has worked wonders for me. When I first had my DZ, It lasted barely a day with light usage. Now it lasts more than a day with normal to heavy use.
Hi there,
I'd love to hear about your battery performance. It seems to differ so much between useres that it's really strange. Maybe we can also find out which apps/widgets are too heavy on the battery.
I''m currently using SGBS Rom 2.5 stock.
My average performance is barely a day with moderate use.
I'm using:
- two E-Mail accounts, one with push
- HTC friendstream widget
- HTC google calender widget
- Google News widget
- display brightness set to the halfpoint
- some hours of WLAN a day, always on with mobile internet
- a little surfing, SMS
that's it. With this user behavior I now got about 25 hours out of my batter. Display is 28%, Phone inactivity is 21%, standby is 16%, WLAN is 13%, Mail is 11%, Phone is 7%, calls are 4%, Android OS is 3%.
I deactivated most of the syncs, push is active for my main active E-Mail, the other one is every 15 minutes. Rest is "once per day" or not at all, HTC sync is deactivated.
Is this performance normal? Any ideas? I'd say it's ok but there are people out there claiming they get 48 to 72 hours out of their phone with moderate use. That's quite a difference.
Thank you!
Battery performance differs from user to user and rom to rom. Some roms will run better than other roms and it also depends on what the user has installed on their phone. If you have a fair amount of widgets or just stuff that runs in the background then your battery life will be worse than other people's. CPU frequencies and governors can also come into account.
So, what's the best way to find out what influences your battery life most? I know there are those stats which I posted but they really don't help that much, do they?
The stats you gave fluctuate too much. The main thing is to keep an eye on your apps. See which apps are running in the background, see how much memory they're using. Widgets are another thing to be careful of. I don't use widgets, just the one since I'm on sense, but having lots can impact battery life. You can try and use an auto run app which allows you to stop apps automatically running on startup.
Try not to use live wallpapers and screen brightness.
Punched in..
I charge it every 24 hours on the average - goes from 100% to 30%. A few phone calls, some emails. Not heavy on messages. Some Internet once in a while. Needs an extra recharge on days when GMaps or GPS or Angry Birds come into play.
Have seen some improvement from Stock Froyo HTC ROM to (over the last week or so) AOSP (Redux2 Test Builds).
Ok then, new stats. I got about 10 hours now with an active time of almost 2 hours and I'm a 70%. Had a short phone call, emails, that's it. Rest was just idling over night.
Main battery culprits at the moment:
Mail 30%
WLAN 19%
Standby 14%
Phone inactivity 13%
Display 11%
Calls 8%
Phone 4%
Android OS 3%
My App Stats:
Options 15MB
Maps 6MB
Calender 9MB
CSPeopleSyncsService 3,9MB (?? no idea what that is)
Google Services 8,9MB (no idea either)
Mail (5,4MB)
Sense 4,3 MB
Market 3,7MB
Mail (again) 6,6MB
152 in use, about 200 free.
Widgets:
Calender
Friendstream
Weatherclock
Google News
Any idea?
So first report regarding the new radio. It definitly works fine with SGBS, can't say yet if batter life really is better:
I'm now down to 68% after 15hours. At least 8 hours of those are flight mode over night. WLAN was active the whole time. Display is the main battery culprit, Telephone "inactive" is right next to it. Then WLAN with about 18%, then Handset standby with 16%.
So I obiously don't know what thelephone "inactive" means, that's still pretty high. But I think handset standby is a little lower. So maybe the radio helped with that?
BTW, I used the music player yesterday for about 40 minutes. And had a short GPS test (works fine with new radio) so I guess 70% after 15 hours is ok...
Hi everyone!
I'm using JellyTime 4.2.2R8 on my DHD.
It's working fast but battery drain so much.
Ex: I only view screen, scroll something. Everage 1 minute, battery degree 1-2%
Who can help optimize this problem?, thanks!

Hi,
I installed JellyTime R8 on Monday evening, and I haven't experienced such a battery drain so far, it goes down a bit faster than my stock Gingerbread+Sense ROM. I might have other stats issues (wrong "on battery" duration, charge stuck at 90%...), but no drain so far.
I am not well experienced in flashing ROMs and how to solve problems, but I have seen lots of people advising to flash the battery stats and recalibrate. But you need a few complete charge/discharge cycles to make it work properly. (But according to a few other people, it's a kind of religious belief too...)
You can also install a more precise battery stats app. I saw a more detailed message in Jellytime Dev thread (in one of the last pages). If I find it again, I let you know.

I cannot find again the thread/post where I saw this information, but the application some people advise to use is BetterBatteryStats.
To give you a counter example: since I flashed JellyTime R8 (Monday 20th Mai, 23h GMT+1), I fully charged my phone only twice.
The first discharge took almost a day (but I used it a lot, configuring and playing with the new features).
The second discharge started 33 hours ago and I still have 50% as we speak. Maybe the stats are wrong, but the phone is still ON after 33hours. I'll let you know how long it lasts.
I am on GSM roaming all day long, but my phone stays most of the time in standby mode.
A few things that I've done to optimize the battery life:
- remove the constant location-tracking, both GPS and 3G (especially as GPS is not working since I flashed JT R8);
- remove permanent/auto 3G connection, as I am spending all the day abroad, it is useless to keep 3G activated, without data roaming on.
Go in Settings/location and switch the toggle off.
Go in Settings, expand Wireless and Networks (Plus), then Mobile Networks and untick the first box (my ROM is in french so I am not 100% sure of the translation, it might be something like Activate Data)

Thanks Matth59 !
I toggled off some setting in phone (GPS, MobileData, effect screen, animation, turn off notification some app...)
But but it does not improve the problem of battery.
I charged full battery, after 24minutes
Saw status of battery on 24m19s, (95%)
Screen 70% (I set bright of screen about 20-30%)
Cell standby 6%
Android system 5%
Phone idle 5%
Wifi 3%
Facebook 3%
Android OS 2%
Media server 2%

And how long does it usually take for it to be discharged?
The second time I charged it, it said that charge was complete and stopped charging at 90%, and I got the impression that it reached that level quite fast. But the device is still on, after 38 hours.
I hope somebody with more experience in that field can give you a better advice or more information, than just flashing the battery stats and recalibrate it.
After one week of using R8, this is how battery is going for me.
On standby, it can last as long as it used to with the stock Sense + Gingerbread ROM (or even a bit more, but maybe because I haven't reinstalled all my apps).
When using the phone, battery life is going down quite fast, and I am not sure if it can last more than 1 day of normal use (3g, mails, messages, calls...).
The most battery consuming task is the screen. It makes me wonder if it could be related to the feature that was introduced by Google since JellyBean 4.1: Project Butter, which makes everything smooth in Android.
Almost 15% of battery drain overnight in 9 hours, with 3G, WIFI and SYNC off, only 2G active.
Yesterday I had 20% of battery drain.
Can please someone help by having a look at the better battery Stats screenshots?
thanks

I don't know if you're Maguro or Toro, but you need to have a data connection or this phone will chug battery. This phone is notorious for chugging through battery when looking for a data connection.
1st time I ever read this...
I have Maguro
left it with wifi and 3g on tonite and list 22%
no one else?
Might be helpful if you name your ROM, kernel and carrier. I have a Maguro with JellyBeer and the newest Golden Kernel of today (with some Trickster mod changes) and only getting like max 5% drain a night.
Edit;
I see it in your sig, so stock 4.3 ROM? I am on 4.2.2 so can't really compare it. Are you in a bad connection zone there? Any unnecesary apps running?

yes, stock 4.3, very good 2G signal, no apps running in background (well I have facebook, but not messenger, and all google apps, of which i use only gmail, gmap and gcalendar, g+ is not connected, still at night sync is off).
if you have a look at the three screenshot on my first post, you will see the servioces causing wakelocks
If you look, the 1 and 2 screenshot didn't influence a lot on battery.. It looks high, but if you pay attention, it's draining 0.9%..1% so, not the beest battery life, but "normal". If you pay attention now on "deepsleep" screenshot, you will see that it drained most of the battery during the night.. So, my conclusion? Maybe some problematic gapps , trying to connect to some server to sync even with sync off, try another gapps. Second option : flash another kernel, it could be caused by kernel keeping the phone awake even when it's trying to deepsleep
Edit : almost forgot.. You could try to connect to wifi, and leave the phone for some hours with sync enabled.. It would sync what the phone tries to sync and fails during the night.. Sounds crazy, but solved my problem once!
Sent from my Galaxy Nexus using xda premium
with wifi on it drained 22% in 7 hours
besides... I not sure how u r reading the screenshot but the one for "other" simply says that of the total monitored time of 9h 14m 54s the phone was in deep sleep for the 96.2% of the time
