Should be in Q&A. I would try reflashing the ROM.
Recently my G2 has been acting up. First problem is when I charge it to 100% and start using it, the battery is down to 0 in 2 hours. This has never happened before. So I charged it again and this time I powered it off because I was at work and didn't need to use it right away. I tried to power it on and the battery was drained when I had shut down my phone. This is with the Cyanogen and Gingervillian ROM. I have no clue what's going on.
Okay yea... There was somebody with the same issue. Also had that problem not to long ago. I found out it was the battery and I called T-Mobile and they sent me a new battery but that's my phone. So anyways have you tried to go back to stock?

I don't think it's the battery because I tried a second battery that I have as a backup and the same thing happened. I haven't tried going back to default yet though. Maybe I'll try that.

Try that do exactly as the app says and see if it makes a difference. If it doesn't go back to stock and then re-flash any ROM later.

Is there any rouge apps open and draining CPU?
Sent from my SilverBullet "HTCDesireZ running CM7"
There shouldn't be. I put it back to factory and the same thing is happening. I've about given up on it.
I was having the same problem I fixed it on cyan 7.0.0...3 hours before battery even started to discharge.

Phone idle is at 13% and phone standby is at 14%. Nah I need to figure out how to lower my android system. Any suggestions.?

So, like many other folks here, I'm also trying to find ways to improve my battery life. Overnight, even if phone is fully charged, with 0 usage, the battery drains rapidly, to 20% by early morning. Android System seems to be the one using the most battery (51%). CPU Spy shows only 15% Deep Sleep time. Since I get emails at night, the softkey lights stay lit all night. I'm thinking that's what keeps the phone from going into deep sleep.
Question is - how do I turn off BLN? I understand many people here love the nitification lights, but I honestly don't care much for this feature.
Here's my setup:
Android Version: ICS Passion 10.6
Baseband: T959UVKB5
Kernel: 3.0.15-ICUP ICS-Streamline #1
Build #IML74K
Juice Defender Ultimate
Wifi connectivity at home and work.
settings-display- uncheck pulse notification light...and yes this will prevent your phone from going into deep sleep!
Perfect
Thank you!!!

It uses power, and when the phone goes into deep sleep the pulse uses enough energy to wake the CPU doesn't it?

Bet it is the email that is preventing the deep sleep and the BLN is a cursory problem bc of that.
now could i do that with my setup? talon kernel on honeycream jw1 2.3.6. i hate the backlight and with it off i could probably get around 3-4 more hours of battery life
Pretty sure backlighting isn't the culprit since it is probably to lightest battery drainer there is. It is what I'd causing the BLN to light up that is draining the battery.
well yes but no. For example psx4droid. If you press on the screen the soft keys light up for no reason and stay lit which uses more battery... that's the only reason I want them disabled,that and I don't need to know when I get texts as I check at least every 20 minutes and each texts means a pulse.... not good.

BLN I don't think has ever had problems with not deep sleeping. I remember Eugene tested his kernel with and without BLN because he wanted to test battery life, hardly any change was noticeable. It's most likely an app that isn't letting the phone sleep.

Even the original creator of BLN has tested the code, and AT MOST it uses a total of 2% of your total battery with the lights on constantly. These are very low energy leds we're talking about here that use a minuscule amount of energy, not 4 hours worth of battery.
It's an app that keeps your phone from deep idle, not the bln.
If you realty want to test, set your phone on airplane mode over night and heck your deep sleep times, and even try it with bln on and then check in the btery to se if your phone reports sleeping (only in gb and above).

Alright thanks buddy I checked today at school and battery life is only affected by a small ammount when leds are on all day

I upgraded the battery to the Galaxy S2 version of 1850mah. I get around 75% after a night's sleep.
Alright I wasn't going to make a thread on this because this topic is already discussed elsewhere naturally but I feel my situation is different. All over the place I see people reporting great battery life with ICS.. well mine is HORRIBLE. I just flashed the latest nightly for Pete's bugless. I didn't change the kernel. Everything is stock. Only a few apps installed. Noop for scheduler and ondemand for governer.
The phones been off the charger for 55 minutes and I'm sitting at 76%. Idk what's going on. I've tried so many rom/kernel combos and I seem to get the same exact battery life no matter what. Around 6-9 hours with less than 1 hour of screen on time.
Things I've tried to combat this:
Undervolting
Freezing apps
Restricting background data
Underclocking
Brightness set to auto
And I'm sure a few other things I'm forgetting about. I've done all this and still get ****ty battery life. I've flashed the new radio hoping that it would solve my issues but no dice. My signal strength reports at -67 dbm yet the bars never go over 2. 3g or 4g. Even after updating plr.
On gingerbread cm7 I ran brightness at 70%, ocd to 1.4ghz and always got 15+ hours.
For the love of god someone help me. Cuz I think my phone hates the cream sammiches.

try this kernel, trinity teuv underclocked/undervolted kernel, oc'd gpu http://goo.gl/rY6ga
and do not set brightness to auto, its a battery killer. i keep my brightness at about 20-25%.
also, be sure to fully discharge your battery then charge it completely, after 2 or 3 cycles you should be good.

I do this every day lol I let the battery drain to around 15-30% before I plug it back in.
Screenie: 1 hour later and I lost another 25% this can't be rom or kernel related. As I have tried trinity already and the same thing happens
Sent from my Nexus S 4G using xda premium
Ugh. Another 20% gone. Its only been a half hour from the above screenie. You guys see my dilemma? Lol **** me.

i was having horrible battery drain after flashing a new rom & kernel - i finally figured it out that my APN settings were messed up and I re-entered them according to the correct carrier settings.
i don't know if that will apply to you since it looks like your 4G data is working properly, but since I was on wifi 99% of the time, as soon as I went off, my data didn't work. but it's something to look at.
4 hours later I'm down to 4% from a full charge.

Could you try better battery stats to see if something is holding a wakelock?
Turn Data usage off :/ i think Fb or some app is using your 4g

I would be interested to see what your battle life diff is without 4g switched on. Also in that 4 hrs what was ur screen on time?
Have you thought of trying a new batt? Just got an OEM Samsung for 5 bucks on eBay. Worth a shot.
Oh remove fb app it blows...install friend caster way better less batt make sure you change the sync interval.
You could also try green power from the market to manage your data use while screen is off.

Ok here's how my battery performs back in cm7 nightly 174 gingerbread. Almost 4 hours and only 25% chipped away. If you look above you'll notice I lost more than 40% in the same time with ics. And I'm doing nothing different. I'm even overclocked to 1.3ghz ondemand with noop for a scheduler.
I think I'm sticking to gbread until official source is out. Maybe then ill get the same battery life.
Sent from my Nexus S 4G using xda premium
That is really weird, if you have time try Milestone 3 and SG's latest kernel and just leave the settings stock . I get wonderful battery life with it hopefully you do to
Oh and are there any apps you are using on ICS that you aren't on CM7?
Sent from my Nexus S 4G using XDA App
Nope. Lately its only been a handful. I actually have more apps installed on gbread to achieve some of the features that are baked into ics. I just don't get it. Ics hates my phone. I even used the GPS today. So weird.

This. If you are installing the same ol battery-draining POS app then you are not going to fix it with any rom or kernel.
So you guys think my batter watcher widget is preventing my phone from sleeping properly? Ok.. I'm on cm7 right now. Battery is def back to normal. And this is with bacround data on. Ill delete bw and get better battery stats.
Sent from my Nexus S 4G using xda premium
Better battery stats is not the same thing as other (mostly useless) monitoring apps.
Look. 16 hours on gb. If none of my apps are killing the battery then what could it be?

I think that's the radio, and it might just be there because it has to be. Might also be other apps causing the radio to be active constantly, though.
Although I don't actually know anything about this (besides that RIL stands for Radio Interface Layer), so I'm probably wrong.
I'm having the same issue, and still can't figure out what's causing it. If you figured it out please report back.

Thats really weird, have you modified the kernel at all? you should try to reinstall the rom fresh.
Nothing modified or tweaking at all, Just complete stock kernel coming from Hyperdrive ROM and I still getting excellent battery life. Weird
