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!

Im facing the same level of battery drain, but i have 3G turned on constantly with updates from facebook every hour twitter updates every 15 mins and mail app every 30 mins. And i mostly use my phone for music and SMS with occasional browsing.

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

Which one did you use?
im on tmobile uk, changes radio from
63.18.55.06JU_6.35.09.26 to
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
before i used to run out of juice around 10 hours after i charged my phone, its not been almost 17 hous and i got 45% left
i seriously suggest doing 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
last night i had my tbolt charging. the phone was off while charging, and it was left plugged in for a few hours beyond the led changing over to green.
after i unplugged the phone and went to turn it on, well... it wouldn't turn on. i did feel the initial vibrate i always get right before the htc screen comes on, however, the screen never came on. i ended up having to pop the battery out and then after putting it back in the phone booted normally.
however, now it seems as though my battery is draining way faster than it has been. i've had the phone a few weeks and the battery has been properly conditioned. after taking it off the charger at approx 2:00am this morning, a mere 10 hours later (whilst completely in standby for the entire time) it's already down to 83%.
what gives? could this just be an accuracy issue with the reported levels? i've read about fully charging and booting in to recovery to reset battery stats. or is it a far worse issue and something has happened to my phone that's damaged the battery in some way?
btw, i'm rooted and running das bamf remix 1.7 with imoseyon's leankernel (running in normal mode with swap enabled).
just a quick update:
after some moderate use (texting, web browsing, downloaded a few market apps) the battery continues to drop much faster than it ever did before. i'm using wifi at the moment.
Have you cleared battery stats lately?
Sent from my ADR6400L using XDA App
no, but i'm going to do just that tomorrow after work when i have a chance to fully charge the phone.
one other thing i just realized that may be contributing to the problem though... my g/f was playing around with my phone and she signed into latitude. doh!
Hi,
First of all o tried to serch something like that all day and didn't found, so, if anyone knows a topic about it with anwsers or some website, pls post it and close the topic.
So, yesterday i took my x10 with 67% battery and connected to the PC to charge and gone to sleep. I use a desktop and it was on all the time. But like 5 hours later, my phone was powered off and completely drained. It only flashed the red light 3 times when i tried to power up. So i connected again to the same computer without touching the pc. It started to blink the flash light for a while, then the light turned green. I waited a little and tried to turn it on. Again, it blinked 3 times and nothing. Connected again and some time later, the charging battery icon appeared, and it started to charge again, and i powered it on normally, and my battery was at 1%.
Even it got no recharge at all, with 67% on standby, my phone lasts almost 3 days, so only 2 options left: The pc is draining it, what i think its nonsense, since it never drain battery from nothing i connect, or theres a bug on the mod, or its a problem on the phone itself.
It's not the first time it happens, but never happen when i used the Miui mod or stock mod. Happen about 5 times already, only on cm mod.
What i already did:
- Reseted the battery stats when it was 100%, drained it until it turned off alone, charged again.
No more ideas.
I noticed something like that too few days ago..
Usually, when I want to charge it from a computer, I turn all the radio (wifi, 3G, sync, etc..) and let the phone charge and its working fine.
Don't know the reason though.
When your computer goes into sleep mode the phone doesnt charge anymore but its not supposed to eat 67% of battery neither ....
Sent From My X10!
I was using Wolfbreak's ROM (v007) up until two days ago, and one of my biggest complaints was poor battery performance. Not sure if it's the ROM or the baseband (52), but when I was at work my battery would drain stupid-fast (100% to dead in 5-6 hours). Part of that I think was that I get poor reception in my office (typically around 99 dBa), but the battery didn't drain that poorly using the old FreeX10 ROM.
I'm now running Jerpelea's CM7.0.3, but still on BB52. So far battery use seems about the same as with Wolfbreak's, but I'm still trying to optimize my battery stats.
Ive used the last few versions of trips roms and on v008 now..battery drain is the only issue ive pretty consistently had with them. Im on bb54..
*wouldnt necessarily call it excessive tho*

I'm on my second LTE (first one hard bricked due to the downgrading of firmware plague).
I'm having strange behavior in the charging of my LTE. When I put the phone on charge mode (computer or wall charger)
the phone will jump to full charge within a few minutes no matter what level of charge the phone had when I plugged it in.
It didn't start out this way when I originally got the phone. The charging process took the anticipated amount of charge to get
to the fully charged state. Now whenever I plug it in to charge it takes only a matter of minutes for the phone to say 100% charged.
It is actually not fully charged but is showing that it is. If I go to TWRP 2.2.2 recovery it shows the actual charge level of the phone for a
little while and then TWRP will jump to show it at 100% charged also.
When I got the LTE from the sprint store and the service person went to activate it, it had the flashing charging light.
He charged it for a few minutes and the charging light became steady. He then went on to activate the phone. Luckily,
he was cool and didn't accept any updates and i found it had the 1.12.0000 hboot. COOL! So I ran home and rooted the phone and fed
the lazy panda. Everything was cool for a while.
I have been running several roms (MikLatTE, MeanRom, OMJ's, and Chaos) and the problem is consistent across them all. I didn't realize that you weren't supposed to calibrate the battery. I had done this several times on my OG. I had installed the battery calibration tool for root from the market and I ran it, and it seems that the problems started shortly thereafter. Battery life has been pretty poor ever since then (16-18 hours with moderate use) where I used to be able to go a couple of days on a single charge. Other than battery and the 3g disconnect issue (that everyone seems to have) the phone is awesome.
I've wiped everything except the internal storage to no avail, and without the ability to wipe the battery stats in recovery, I am lost as to what to do next. Any ideas would be much appreciated.
Hardware 003
ROM: Meanrom 4.6

You shouldn't have a problem upgrading your firmware, but its probably not gonna help your battery situation. It is recommended to have the latest radio and firmware with the newer ROMs.

1. Charge over night with the phone on, then go through the whole day until the phone dies on its own, dont charge it or turn it off until it dies. this will help calibrate the battery. what may be happening is that the phone doesn't know the minimum voltage of the battery since you used the app so it is reporting the battery wrong.
2. absolutely update your firmware. i recommend the bootloader method.
3. also, HOW DID YOU GET A FEW DAYS ON A CHARGE? 16-20 is like a very very good day for me. multiple days is out of the question haha. do you like never use your phone? lol
edit: tell me if that works for you

The battery level dropped quite quickly the first two hours (-20%). I at 14.5 hours right now with 24% left.
I'll let it go completely dead before I restart or plug in. PS. I updated the firmware and radios, and all is well with that.
I've been using my Verizon Galaxy Note II since mid June (I got it brand new). It's rooted and always has been, however a couple days ago I was running Jelly Beans build 21 and I ended changing to the HTC Sense Recent apps (I don't think this is a problem, but a coincidence) and after a day or so I plugged my phone into the charger before I went to sleep. However I realize it wasn't charging. I tried unplugging it and plugging it back it and it didn't charge. I changed outlets and no charge so I restarted my phone and it started charging. Ever since then however, my phone has been dying quickly. Maybe losing 20% battery life within an hour. It also charges really slowly now, too. I used to get from 0% to 100% within 1.5 hours to 2. Now I'm at 25% and it says it'll take 3hr 45m to reach 100.
I don't know how to fix it. What heats up is not the battery, but the GPU/CPU area. I changed ROMs and it didn't fix. I also used ODIN to go back to unroot/stock which SEEMED to have fixed it (I lost 3% in 40min compared to 3% in 5 or 7m). But after using it for a little while, it seems to happen again. I then re-rooted and restored from back up to the new rom (not JB 21) and it's happening. I'm currently charging it to 100% and then I'll let it drain and monitor it just in case there is a main problem. I'll also try a different cable tomorrow.
However, I was wondering if this has happened to anyone else or if anyone else has suggestions?
As an FYI, I've
- Turned off DATA
- Tried charging while the phone was switched off (it does cool, but charge time doesn't seem to improve which might be because of the 700-900 amps I'm getting.)
-Underclocked to 1.4ghz and undervolted by 75mv on everything
-Turned on Power Saving mode
-used Greenify for many apps
-Factory Reset
-Reboot
I haven't:
-Let it go from 100 to 1% in order to correctly monitor battery killers
-Tried a clean unroot, back to stock, root, clean flash. (I've done it all except the clean flash [I restored a backup])
-Other things I can't think of
