Would lowering the clock speed on my G3 from 2.5 Ghz to around 2 Ghz help my battery life much? I understand there could be a slight performance hit but the AOSP ROM I'm on is very light and I feel like it would still be plenty smooth. Thanks!
Since the display is eating most of your battery power and underclocking your cpus won't help there, it will do you a LOT less good than you might be thinking it would.

I switched my governor to Conservative. On this quad-core beast, it's sipping battery and I detect little if any lag anywhere. Right now I'm at 17hrs 20 mins on battery and at 65% still. I have 2 hrs and 15 minutes screen on, and another 15 minutes in phone calls.
Also, using TricksterMod, I've set Multicore Power Saving = 1 to help keep 2 cores off as much as possible. Deep sleep is at 76%. Granted, I usually use my phone a lot more than this and expect to more through the day. I'll post an update later.

Guys can anyone help me with battery life? I'm running cm7 nightly 9 and I've wiped battery stats. Also reduced friendcaster polling to 1hr after seeing the betterbatterystats screen

Everything looks normal to me, and the wakelock didn't show any program that's drainging the battery bad...The Wifi didn't use that much battery too according to your pic. Display didn't use that much also(17%). So I say it might be your weak 3G/GSM signal that's draining the battery.
Thanks man! anyone else?
I was doing some browsing and downloading for a good 2hours or so before leaving it at 30% for about 8 hours with wifi turned on. Woke up to 3% battery
If that's a 2h period you have a display-on time for those 17%, and the rest of the drain is due to a severe case of the Android OS bug. 25% drain over 8 hours idle is horrible. Sadly, no real solution to it other than just trying around wiping the phone and playing with the configurations. **** percentages in the battery screen and look at actual uptime of the different things.
This dont usually happen. In fact, it only happen once.
All this while, the display always use the most battery life, about 50%
followed by android OS, about 10-15%.
my phone was fully charged before i sleep.
but i woke up with 5% battery left, the battery info says android OS used 60%!!
here is screenshot as proof.
i'm really confused, the phone state is appear to be NOT awake,
but the CPU usage is 1000MHz constantly while i sleep.
all this while i've been using rom tool box CPU slider to underclock it to 1000MHz, so thats the maximum my phone can go. i prefer it that way so its much less warm.
any idea whats causing this? as i mention before, this only happen once.
Even so, i'm very curious about this. any one experience this before? or know whats goin on?

I found the BatteryCalibration app didn't do much for me but letting the battery drain down to 0 then charging over night with the phone off up to 100% worked and fixed the battery %.

Ok thanks I'm going to try that hopefully I have the energy to kill my battery before I get tired maybe a lil gta 3 at Max brightness + wifi should do it although It has lasted 13 hrs. And is only at 57% .
Thanks

Hi,
I've tried a couple of roms recently, but I am a bit bothered by the battery usage by "Android system".
My phone is only giving me around 4 hours of screen-on time.
Sometimes, these system processes:
Binder_2
kswapd0
Peak my phone CPU usage. Under "screen", they are usually the top consumers. Is this normal?

Here I was playing ingress on and off for around 4 hours. For those of you who are not familiar with it, this is a game that uses GPS, Wifi, a mobile data connection, and your GPU, all at once. The battery drain was so bad I had to plug in my battery pack just to get through these 4 hours. And note - the screen was not even on the whole time! Point being, android os and android system managed to consume more power than ingress for that period of time.
I see nth wrong. Looks logical.

Give a thank if I helped you

So far, this phone has the best battery life of any phone I've ever owned. By far. Part of that appears to be incredible standby efficiency, which isn't shown in the standard battery life tests the various blog sites run. I waited for several days to give things a chance to settle in, and on the 5th day charged the phone to 100% before going to bed. Nine hours later, it had used only 5% of battery. No other phone I've owned has come close to that. (Another night, I turned AOD on, and after about 8 1/2 hours battery was down 11%. Not too shabby.)

22 hours, and 5 hours SOT later, I was at 38% battery. I've never gotten close to 5 hrs SOT before. If I got 4 hours, I was down to 10% battery or less. (My eyes ain't great, so I probably turn the screen up brighter than a lot of people do.)
So far I'm pretty impressed with this phone.
