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 unplugged my phone from the charger after doing this at 6am, it had 100% charge
its now10:45 pm, i have 44%charge left...its crazy

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
Hey Guys,
(I've searched and unable to find similar issues, sorry if this has been answered before)
I'll keep this short because I'm sure you've read something like this thread a thousand times.
I recently moved to Gingerbread (CM7) on my Vibrant and my battery life has dropped considerably. Today my phone died in just over 6 hours after being unplugged from 100%. I've wiped batt stats, wiped dalvik cache, depleted the battery entirely, charged full and still have these issues.
Please take a look at the gallery link posted (Includes Batt Stats graph, batt stats themselves, including BetterBattStats screenshots).

Does anybody have any idea why the phone would be fine for a few hours in the morning, and then just start dropping like mad? If you look, the phone wasn't awake during that type, and there don't appear to be any apps that are eating CPU
Ideas?
Hello,
I have a problem with battery on my Samsung Galaxy S3. Let me tell You my story.
After buying my brand-new phone the battery life was quite ok, I could be using (games, music, internet) my phone for almost all day and I was charging it every night. After two years of using, I rooted my phone and installed CyanogenMod 11. Then the problem appeared - after some time the screen was flickering and device was turning off. I was really confused, so I changed my rom to another, then another, another etc. Then I saw my battery is swollen. I bought brand new, original battery and used CM12 for maybe one month. I changed cause of battery, about 3-4 hours. Now I'm using Android Revolution ROM which is modified stock ROM, but has improved RAM use etc. Now my battery life is much better, but it can not afford more than few hours without battery saving mode on, or 8-10 hours with battery saving on. Here You can see a screenshot from my phone (I would post this but spam setting don't allow me)...
Is it normal? I thought battery life on my phone was better. I haven't made any battery calibration. Should I try this out (cleaning battery stats)?
Thanks for Your answers.
There is no normal for battery life, a rough guide is 5hrs screen on time from one battery is good. Unless you run battery stats you won't know what the problem is.
It all depends on how you use your phone, I use mine completely differently.
When S3 was my primary phone and I used him extremely hard than battery needed to be charged every day. Now, when I'm using him occasionally battery remains operational even a 5 days.
It is not normal in daily use to charge every couple of hours especially if battery is brand new. Of course there can be power leak on IC chip due to overheating in past but usually apps and wakeloks respond for quicker than normal discharge.
Maybe there is an app in your play store shelf which drains battery juice. Try to flash any firmware you like but do not restore your apps. Try using your phone per one day and check how it goes.
Meanwhile you can install cpu spy to check deep sleep state. Also an app for wakeloks diagnostic, ie gsam or better battery stats.

Okay, I downloaded Wakelock Detector & CPU Spy and going to take a look how my battery is being drained.
I did a complete charge last night before I hit the sack. Battery was around 96%, today morning 80%!
I flashed stock ROM using TWRP, on first charge cycle battery is fine - just 1% overnight drain with 8 hrs SOT. On second charge cycle this issue hits me everytime.
All my radios are usually off (WiFi, NFC, Bluetooth, Data).
Android system sucks my battery during sleep and it was at 90% consumption when I woke up (See screen shot #1).
My phone seems to be in deep sleep a good portion of that time (See WLD statistics #1).
Also attached screen shots from WLD for Summary, Kernal / Partial wakelocks & Alarms.
Device is rooted.
Going crazy trying to find out what's happening.
I have tried 3 different ROM's which have great battery life as reported by other users here for my mobile (Mate 8). But I always end up with the same battery drain issue on second charge cycle after flashing a ROM.
.
Bump! Anyone?
Any experts that could help out here?
I have searched a lot but no solid solution.
Hey I hope you guys are doing great !
Well i bought this phone like last month and the battery was working fine for the first few days but then its battery started decreasing faster than before while using the same apps as before. The most battery drains while its still in the idle conditions and overnight.
At first it would only loose like 1 or 2 percent over night but now it looses like 1 percent battery every hour it stays idle.
I have attached 2 screenshots below to show what I'm talking about . Both screenshots were taken 1 day apart and as you can see , sometimes the battery works fine but sometimes it drains a lot and its mostly when its idle. Kindly suggest me something if you got anything in mind that what might be the issue here.
Maybe the radio of your phone, that's what's draining mine fast.
And Facebook is a well known battery drainer
If you tap on the graph once, it allows you to find out the battery drain for specific time intervals and their length can be adjusted as well. Please do that and tell us which app or apps are draining the most battery during standby. Btw is your aod on? Aod prevents the device from sleeping properly so the battery drain can rise up to 2% per hour if its on. If that is not the case as well, try turning off location and nfc if they are not being used, and turn off wifi and cellular before going to sleep and then check the drain. Also try disabling google play protect from play store, and check out the link below which improved battery life for many people including myself:
