Has anyone else noticed a significance in battery life?
I have an average of 56-60 hours my max idle was 81hrs....

I've gotten slight improvements, but what you're getting is insane... how'd you manage that?

I could never let my phone idle long enough to find out how many hours it would last. But I easily get a full day on cm7 with my regular use.

Only had it a day. But from where i've noticed holding the wildfire/aria next to each-other doing the same tasks with wifi on [ones got service, other doesnt yet] the wildfire was out to 80% in less than half an hour streaming music from pandora. Aria was at 95% with CM7 [even overclocked]. Although the wildfire is approx 3 months older, that seems amazing in my opinion.

Ultimate juice our even juice defender with power control plus..both have free and almost the exact same it's insane.
Anything to toggle data is recommend for battery life, but that's a given....

Just my 2 cents, A profiling tool for over/under clocking. Over for when your hard at work, playing videogames and whatnot. And underclock for when the device is serving 0% use. That seems something that should be implemented into android.

I agree thats what I did as well, cm7 seem to make swype better too, idk why... The only straw back is my juice defender doesn't data toggle on screen off/on...i miss that lol att rapes in data lol....

most custom roms, especially aosp ones, give you a much better battery life because they put the control into your hands; you can customize your phone to be used how you see fit.

My battery life is improved with cm7 over cm6 with most things being equal. A welcome change I might add.

I think battery is much better on 3G data but much worse via Wifi. I manually change to use them mutual exclusively.

3 hour Battery life On CM7

After calibrating, draining and recharging and wiping stats a thousand times, this is what I get:

2 hours of screen time there, that seems about normal to me. I'm lucky if I squeeze out 3 hours of screen time throughout the day.

It depends entirely on what you are doing. 2 hours of screen time (even in ideal conditions) will most likely get through half of your battery.
What screen brightness settings do you use?
What were you doing with the "screen on"? (i.e. gaming, video etc).
What kernel do you use? Try the Faux 1.0 Ghz kernel (if not already) and consider undervolting.
I imagine with the combo of Faux's stock kernel, undervolting and perhaps reducing screen brightness will see 5ish hours of screen time.

It was on around 85% brightness due to being under direct sunlight.
My kernel is faux's 1.45 for CM
Over 80% of the time the clock was around 200, 400MHZ as stated by SetCPU, and both those clocks are undervolted by 50.
I was browsing the whole time.

Wow no wonder. Roaming for 2 hours with brightness nearly on full will definitely drain your battery.v Plus the 1.45 Ghz kernel overclocks the RAM and GPU also. You might want to get an anti glare screen-protector and flash the 1.3 Ghz kernel and use wifi.

Umm... wifi wasn't an option back there, and I don't use screen protectors. BUT I didn't know that bit of fact from faux's kernel, I'll put in the 1.3
BTW, Green power pro does help a ****load on keeping battery alive.
ps: anyway to control RAM and GPU clocks the way we do with SetCPU with the... well... cpu?

Why don't u go to a stable version and see if the battery drain continues there also ? You can always create backups to restore right ..

Have you tried installing better battery stats and CPU spy to see if you have a rogue app? You should be getting significantly better battery life. How is your cell signal?

I don't believe setcpu functions correctly for dual core devices, I remember reading, albeit a while ago, setcpu only effects 1 core, leaving the second untamed.
Please correct me if I'm wrong. Stock cm kernel has plenty of ass behind it, no ones playing bf3 on their handsets....yet...

In all actuality, android isn't optimized for dual core devices either. ICS will be.

Watchdog shows the suspend process and android media process taking up about 30% usage constantly. Signal is strong when I'm at work, constant 4-5 bars H+
Even after a full wipe and clean install of CM7 those same processes throw up alerts immediately, I will get al alert for the suspend process every few mins.
Background data off, no email syncing or anything. I'm lucky to get 3 hours screen on time or pandora streaming. I bought a new Motorola battery about a month ago and I don't use GPS or wifi.
Running stock, aura or homebase and the drain is gone... they aren't any good IMO tho.
For now I'm carrying a spare charger everywhere I go till the nexus prime is released.

Someone help me! (BatLife woes)

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

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.

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?

Battery Life on CM7 (AOSP versus Sense)

I've been running the latest nightly (20120722) for a few days now with less than stellar battery life. It seems that everytime I run an AOSP rom the main battery culprits appear to be cell and phone idle, where's with a Sense rom, it' the screen. I have a relatively new battery. I'd say moderate use, typically.
Anyone have suggestions on getting better battery life with CM7? I'm running the stock kernel at 245/800, ondemand, deadline. Also running V6 supercharger at 5.
Any advice is greatly appreciated. Thanks!

I've gotten 12+ hours today of cm7.2 7/15 nightly and barely at 50%
Did lots of recordings and such.
Dunno
I don't use the v6 script, or do any mods at all.
Just run it as is.
Stock battery too.

Yeah I've gone back to 7/15 to see if it's any better. I seem to remember it being better; I'll report back later today. Still curious why cell standby is the main battery eater on CM7 (or AOSP ROMs in general) as compared with say, SSX or newSENSE, which was the display...

Aosp shows true signal where Sense won't. So AOSP having a cell standy over display sounds about right. Sense always thinks it has signal and AOSP has no signal thanks to sprint. In my area Sprint blows, so that's what I *think

This is better.. I went back to the previous nightly (20120715) for a few days now. Still moderate use.
I'm currently running the stock kernel at 245/1.21, ondemand, deadline. Without V6 supercharger and I didn't flash the ICS theme either.
Perhaps the 20120722 nightly did not play well with my device.

If V6 SuperCharger is not setup correctly, or the setting is to high. Your Battery life can take a hit.

which rom/kernel gives better battery life?

hi, just my nexus 4 and rooted it straight away
currently using cm10 with franco kernel.
so far so good but i would like to know which rom & kernel combo provide the best battery life? i am not a heavy gamer so cpu/gpu intensive tasks are not essential to me.
any advice would be great

you have the franco kernel updater app?
use betterbatterystats (google for it.. you can find it for free on XDA) and ensure no wakelocks. ensure your phone is properly deep sleeping
google maps -> settings -> location -> disable automatic reporting and the other checked mark (update your location)
news & weather app -> settings -> refresh interval (set it to once a day or manually.. depending on how often you use it)
