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.

Hi everyone,
This is not a battery life problem. I've read the battery threads and could not find someone with a similar problem.
My problem: I left my phone locked and untouched while I went shower. Afterwards I decided to check my phone but it did not respond. I tried to turn it on but that failed too. The screen stayed black as if it was off. I ended up taking the battery out, putting it back in and turning the phone on.
The phone did turn on but my battery temperature was 45°C and 48%. My battery was 75% before I went shower. I checked the battery status page and here's what it showed. Notice the vertical drop in battery at the end of the graph.

After a few minutes since restarting:
The android os % also has never been this high before. I've also never experienced any battery problems mentioned in other threads. I use my phone quite often so display is always at the top. This is the first problem I've encountered with my SGS2 which had made me quite sad since it's less than 3 weeks old.
Thanks for reading and would really appreciate any input.
Just curious, do the blue bars beneath the graph correlate with the time axis above it?
Would I be right in thinking that my battery life plummeted as soon as I turned off wifi?

Yes. Probably more likely to be related to screen on, and possibly mobile data. Depending on the brightness, it seems like 4-6 hours of screen on will eat the battery.
Yes it does correlate.
The thing is you just had WiFi on for some period, but you didn't do much in that specific time, it was just on. But just after you had turned it off some apps or processes kept running and you also used the device.
That graph looks pretty fine to me.
Regards.

That's not true screen by itself will not eat battery so fast , review site did media playback test of SD material and battery lasted little over 9 hours.
Only combination of radio+CPU+display will get you 4 hour mark, that's worst case scenario.
Cool, thanks for the replies. Makes sense now
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?

Better Battery Stats thread and partial wake locks is your start point .

Hi everyone
i have a strange problem that happens often with my phone,
i noticed there are some certain apps or games cause my phone to consume power more that usual.
what happened was, i fully recharged my phone, then installed (Where's my water, the free version) from Android Market last night, and i played it for a while, then i went to sleep and the phone on the stand by mode.
when i woke up this morning and i found that my phone lost almost 40% of its charge over night.
the only solution to recover from that high power consumption is to restart the phone, but it is really annoying!
i took a snap shot to the power graph and i made little explanations on it.

Sorry for bad English!
Download better battery stats from the market and it should tell you what was eating your battery. I'm guessing an app is keeping your phone awake. Check your uptime and awake time to see if it seems to close in numbers.
thanks for reply, but as you can see from that picture, the phone does not show awake condition while it consumes power.
anyways I'll try to install one of those battery monitor apps to identify what's wrong with the device.
thanks again
please help
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.
