I previously made a thread regarding low battery life.
After a week of use and more testing, here's what I gathered.
(Note: I have GPS, Bluetooth, Wifi always disabled, brightness lowest)
My phone will completely drain out in 6-7 hours.
I found the culprit: Cell Standby
1.) Cell Standby always uses the most battery, often 60%+.
2.) Phone Idle often follows with 30%+.
So, to verify my theory that the screen isn't the issue, I turned on airplane mode.
I proceeded to watch a 1 hour comedy, and battery life dropped from 60% to 50%.
This is lower battery usage than if it were sleeping with cellphone on.
I then noticed that my signal hasn't been good (provider sucks, no choice, all of em here sucks).
So, I placed my phone on, but asleep inside a locker for 2 hours (no signal).
When I took it out, it was very warm at 40+ C and battery life dropped about 20-30% per hour.
I've tried turning 3G off, turning always-connected off or downgrading 2g.
The result has always been the same. It still sucks bigtime.
It seems like Nexus One also has this problem, anyone notice similar problems?
I've googled and been told that this is "normal", because the phone increases power to secure a signal.
However, I've clearly owned phones and placed them in signal-less lockers prior to this, and trust me when I say most of them drop 5% per hour max.
20-30% per hour is horrible, and clearly the phone is overpowering its components.
There are some certain Radios you can flash to improve how your phone uses power to pick up a signal, Requires root access tho.
Can you please point me to those radios? I've already tried updating my radio to latest.
My phone is already rooted.
My battery is a joke and I have tried many different things. I always have to charge it by around 3pm everyday during week as It will almost die on way home.
I take it of charge at 7.30am by 9.30 it could be down to 86% and then it judt continues to drop by 3 It can be between 60 and 50% if lucky, by time i'm tenmins from my house I get 15% and warnings.
I use basically for txt, some net usage and sometimes playing a game 10 - 20 mins tops and or read ten mins of books.
I have all updates off only manual and screen down low etc - doing my head in!

Strange, I always have 3g on, and still play a lot with my hero (games and such)
Still it survives about 36 hours on 1 battery load. Without 3g it holds out for 72 hours.
Post #1 on the thread below seems to have a working solution (re-interpreted below)
It seems to be something to do with the battery stats and charging via usb through PC instead of via the mains.
You have to clear your battery data when your phone has really really low battery (this is probably the MOST IMPORTANT step) (you can do this through recovery mode in amonRa). Once the battery data is clear, switch back on (before plugging in) and drain the battery so that your phone switches off by itself (playing music loud and switching wifi, data connect etc, etc is suggested in the thread).
Once battery has died, plug in your phone WHILE it is STILL OFF, then when the battery shows green (will probably take longer to charge because this time it is getting a full charge), UNPLUG BEFORE you switch it on. and you should notice the significant difference. - Oh yeah make sure you switch off all those data connections and wifi and all those other things that you used to drain the battery - unless you use some of them of course
EXTRA TIP given on the thread: TIP!! Remeber when changing and flashing new roms to unplug the phone from charge *(i.e. unplug from your PC) (edit Bad4ss) * after you boot!
TO answer LennyUK's Q below ( and so that the next page doesn't start to quickly before this suggestion is read ) I think why it is suggested for the first boot after this process to be done while off is because it is already off because of the drain AND because it will get a clean full charge up for the first time after a battery data wipe. Because while it is on it will be depleting the battery even if it is in a small way - after that you can do it whichever way you want *nudge-nudge-wink-wink-say-no-more*

I don't see why the same thing cannot be achieved by charging with the phone on, just as long as you don't change between phone being on or off during the charge i.e. if you start charging with the phone on leave it like that the whole time and visa versa

Can you do this on non rooted phone? How do I get into recovery mode?
I think the analysis is flawed. I also think the stats information doesn't tell you everything. For example, yesterday I had 60% cell standby, 20% WiFi, 20% phone idle. Consumption was 45% in 24 hours.
Previous to yesterday, I had high battery consumption. So yesterday was a breakthrough but YMMV. I removed the PCSCII and the Mail app (I don't sync with Exchange and I don't sync with a PC as such - I don't run Windows). I also disabled auto task killer. I rebooted without being connected via USB to power or to PC. Suddenly power consumption became similar to Modaco ROMs.
Last night, I also disabled the setCPU application and rebooted. 6% battery consumption in 9 hours. 34% cell standby, 33% WiFi, 33% phone idle. Consumption was 45% in 24 hours.
how have you improved battery usage, ive tried resetting battery stats, draining battery, fully charging, using kimera 1.5 and with no wifi no bluetooth, not using phone in few hours it was down to 63% and in 10mins had dropped to 59%
i had similar battery problems but today i changed radio versions into a different one, now i get almost full signal all the time and battery usage is geatly increased (went down 2% in 4 hours as compared to 10%/hour)
so i suggest finding a radio that give you good reception

63.18.55.06JU_6.35.08.29
made alot of diference
you should ty out diferent radios and find one that gives the best reception, it will be different for different providers and countries
also i did this...

I will use that radio too seeing as I too am on T-Mobile in the UK. When you say to use the link and suggest doing it, I take it you mean the "get to 10% -> get to recovery mode -> wipe battery info -> reboot and drain battery 'til off -> charge while off and the take off charger once charged and switch on..
'cos I tried that and still having problems - am using the new Villain 4.0 beta2, so maybe the radio change in combination to this is what will work - I'll try it tonight when I get home.
immya : many thanks i now hove phone back
flashed radio 63.18.55.06_6.35.05.31
and lost 1% over night
previously on LOST
radio 63.18.55.06JU_6.35.09.26 lost 56% overnight
perhaps issue with 2.1 roms is the latest radio and not latest kernal
BTW using sensehero at moment as was trying 1.5 roms to get better battery, and that didnt work.
some one maybe sticky this info , if anymore find it a saviour. will report back after work, mayeven be able to use data syncing again
I been using using the the Elelinux gingerbread rom and have not have the greatest battery life I turned off wifi Bluetooth and my internet connection on my phone and in a hour I lost 15% I did not to anything in that hour does anyone know how I can increase the battery but I never lost 15% in an before like that I normally lost 0% but today when I fully charged it this happened does anyone know his to increase the battery life
Go to:
Settings -> About Phone -> Battery Use and check what is draining your battery.
You may also use consider lower Min CPU frequency. I'm running on 19 MHz.
i did nothing it that hour with my phone all i did with my phone an placed it on a table and watched tv
You might did nothing but some widget could drain battery like hell Check battery usage as per my first post. I'm using Elelinux-7.0.0-RC0-Hero-v0.7 and my battery life is very good, with all stuff "on" except BT.
but after i while the battery life a bit better
Have you tried to reboot? I just realized that after first reboot after I flashed new rom Android Service process was draining my battery like hell (3 times more than Display), my phone was down within 3h. But after I rebooted everything was ok.
Hey everyone,
So am an X10 user for a year now, but recently am facing an issue with the battery...well the phone's temperature rises up to 50 degrees celcius, which is burning hot... this ofcourse kills the battery in 2-3 hours from 100% to 0 i had to charge it 3 times in 12 hours .
My usage is as follows:
- Bluetooth on
- Wifi, GPS, 3g off (occasionally turned on)
- Apps killed, just a few are running in the background (where i make sure that the memory has 100MB min free)
- Screen timeout 30 sec
I cannot find the reason y the phone heats up like that.
Anyone facing the same problem or has a solution for that??
Thanks
Do a full reinstall with SEUS. And then take a look at which apps drains your battery by installing all apps manually etc...
Yeah and if that doesn't work just go to xrecovery and wipe the battery stats then charge your phone to 100 percent. Make sure your phone is fully charged when you wipe the battery stats though

Well, i have been trying a technique for a few days now and i think its working.
So i leave the battery till it totally dies then i leave the phone closed and charge it for like 8 - 10 hours, i did that for few times, and to my amazement, the battery life increased a lot.
Well done.. i think i said this before.. and alot of guys fobbed me off.
I'm on Axura 2.2.7.2 and have horrible battery life no matter what battery I use.
For example, my battery percent is at 63% right now:
4h 48m 38s since unplugged
Display 90%
WiFi 5%
Cell Standby 3%
Phone idle :1%
The weird thing is that I don't really use it a lot either. I used it for maybe 20 minutes max. Talked on the phone for 5 minutes, made about 10 texts, and checked the time from my phone thats it.
Also, I'm using Zeam launcher, could that be the problem?
Please give me some tips on how to maximize my battery life.
You have to calibrate your battery. Download Battery Calibration from the market first, then kill your phone all to like 5%. Charge your phone all the way up to 100%
Then click on the calibrate button on the Battery Calibration app. You should be good after that. Make sure your unplug after calibrating and die the phone down again, and then charge is back to 100%

please go to settings / about phone / battery use and post what is consuming most of your battery so we can help u better knowing what the problem is.
there are a lot of ways of improving battery. the best 4 me so far is a custom kernel that allows undervolting which helps a lot without affecting performance. underclocking if u want to go the extra mile, and lowering brightness helps too since our screens are battery hogs.

Battery Life Help
Under Volting does not work for me...Making sure I run the battery down all the way and charge it full most of the time especially after deleting battery stats.
Since Jelly Bean release ive noticed that the battery life hasnt really improved for me. Actually its gone to worse. Normally i dont use my tablet very active, so there were cases when i had 10 days between charges. No, even without using, the battery holds maximum of 4 days.
I dont have wifi lock, i have disabled backup, only have synchronisation of gmail and drive, but i had those on before aswell.
What i see in the battery graph is that even when wifi and display are off, something still wakes the tablet every 10-15 mins or so and drains the battery. In the stats it says that the "Standby mode" has the most usage...
Could anyone help me with some app to diagnose that problem or share similar expiriences..

I resolved my battery problems using Wakelock Detect:
https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en
You might want to give it a try. Turned out that some badly written application was holding wake lock on my XTS and thus jeopardizing the battery life. I also use Battery Monitor Widget:
https://play.google.com/store/apps/details?id=ccc71.bmw
It won't tell you source of the problems but it will tell you how much battery is drained when your device was sleeping.

Btw. for WLD enable advanced mode from settings. It was system process which was holding wake lock and by default, WLD does not show system processes at all (!!!).
batery life always been awfull on XTS it was't bad but it could last easy 3 day's on single charge if sony optimise it.
my nexus 7 i can easy achieve 2 day's on single charge maybe 3 day's and it only has like 4200 mah batery with wifi actualy staying on always.
now in standby only drains like 1% batery per 3 hours
XTS always drained 2% per hour for me in standby

Wtf, that would drain the battery in two days?! Definetly some program has wake loke on your device. I havent done any measurements, but I think I've left my device on my table for week and read E-mails every now and then without any charge and it still has some juice left!

Update on thread:
I found out Google Maps was waking the sysem every 10-15 minutes to look for a location, even tho GPS and Wifi were off. I disabled Latitude and automatic locking on location and also disabled every location option possible (use wifi to lock location etc.) and now its better..
