[Q] possible battery issues with darkside digital warfare - T-Mobile Samsung Galaxy S II SGH-T989

I can't seem to get the battery results people are claiming. It seems like I lose 10 percent usage per hour during the day. I am starting to think I might need to replace my battery. Last night I left my phone unplugged and It drained over 25 percent with 7 hours sleep. When I installed the rom I used the wipe flag. I haven't touched a CPU controller cause it was suggested not to.
How do I find out exactly what is draining the battery so much?
I heard about battery calibration. I have read about a few techniques. I have also read that it is a placebo.
I am not sure what to do. Here are some screens. The drainage doesn't seem normal.

Battery life really depends on the user much moreso than the rom. are you constantly using gps? google location? Wifi? Facebook sync? Twitter sync? Google talk? Other im's thru social hub? max screen brightness? constantly receiving calls and texting?
All of these factors influence your battery life. its probably not the roms fault.

I am not saying its the rooms fault. I am trying to figure out what is causing the drain. I don't use social hub or the Facebook aphp. Only thing I kesync is Gmail, contacts, calander. Also, I use gtalk. I don't GPS at all.
Something is draing the battery.

I would say it could be any number of things, however the question is, what have you changed recently? Any updates, new apps?
Also, with this increase have you seen any decrease in your battery usage? I will have 70+% android usage sometimes but battery doesn't drain any faster. This is a normal thing for AOSP especially. Someone noted that they had high A.S. usage on a stock Nexus 4g.
This may just go away with a days usage, but be sure to check for partial wakelock. This option is in Spare Parts app not sure if its built in to MIUI. The wake lock is what kills your phone, when an app goes bonkers and keeps your phone awake.

True. Miui has updates every Friday. So yeah, i updates last Friday. I switched from tiamat to savagezen just so i can fix the high usage but to no avail. I can't check battery partial lock because miui has battery stats issues right now.

In addition to what imheroldman stated, charging your device will oftentimes cause your android system usage to spike, but 20% is nothing to be concerned with.

[Q] G2 Battery Life Issue

For the past couple of weeks ive been having issues with the battery life on my G2. I used to get 12+ hours of battery life on it but now im only getting about 7 or 8. Ive tried recalibrating the battery, clearing the dalvik cache, and changing settings on certain apps but that hasnt seemed to make a difference. Ive noticed that at the end of the day, the android system takes up a huge chunk of my battery. Any ideas?

I've had the same issues as the builds of CM have gotten higher in numbers. The ROM that's given me the longest life is the stoock Gingerbread rooted ROM. I switched back to CM because oof the Text MMS & them always being Slideshow issues as well as no ability to stoop the phone from vibrating when I'm on a call. Same issue with CM too actually.
I'm bumping this because I feel your pain.
you can fix that in call settings you know!
Are you running CM7? If you are, open up spare parts and look at the battery information under Partial Wake. See if there's something tying up the system.
There are a few things listed but I dont think its anything that would eat a whole lot of battery. Should I be looking for something in specific?
Anything that's more than a sliver is eating the battery and keeping your phone from sleeping.
I'm getting 24 plus hours on glite which is aosp also. Maybe the battery is finally giving up the ghost. They do have a finite amount if charge cycles. If nothing else has changed and all things being equal to your 12 hour charge cycles maybe you could try a different battery.

Finding apps keeping GN awake?

With ICS what is everyone using to figure out what apps aren't letting the phone sleep properly?
Spare Parts isn't working.
I've tried uninstalling about everything and I can't get this phone to sleep.
This is exactly the post I wanted to make today, glad I searched this one out.
I have few apps installed, and battery is going well for me. I'm a moderate user. I get about 20hours out of a charge.
I notice that even in airplane mode, my phone wakes up 3 or 4 or 5 times during the night for 5 or 10 minutes at a time it seems. What could this be? It's not data as I'm off wifi and in airplane mode. Any ideas?
Thanks all.
I've also been experiencing fairly high CPU awake times and was curious as to how I could track it down. Haven't found anything much yet in the way of apps, but I've turned off a lot of unnecessary Google syncing and an hourly sync of my Exchange account and it seems things are better now. I'm still getting awake times 1h30 greater than screen on time though.
I am seeing high "Keep Awake" times on Android OS Spare Parts force closes when I try to check Partial Wake usage so not 100% sure what this could be.
Wondering if this is the cause of some lower-end battery life we're seeing. My only thought would be LightFlow that is causing this (maybe to wake up for notifications). I thought I read it somewhere, but not sure if it was debunk'd or not.

What killed my battery?

What the heck killed my battery? This is with the extended battery and I started from a full charge after flashing a new rom and clearing battery stats..
I turned off all connections, and turned off sync.. Sat the phone down and went to bed after about an hour of web surfing.. I went to bed with 70% left and woke up 6 hours later with 37%...

Its all in the last screenshot. Keep awake time is huge. That's the bug if I had to guess.

That keep awake time is normal, nothing strange there...
Your story of browseing for an hour then going to sleep for 6 hours doesnt match your batteries' graph.
According to your story, there should have been a sharp decline from browsing web since the screen would be sucking the power, then a very slight decline from being idle, something was either running in the background (facebook maybe, it has a high % of usage) who knows?
Yeah idk.. If you look at when wifi was on that was when I was browsing.. Then after that there is a steep decline which doesn't make sense to me.. I don't think it was Facebook or anything because all data/sync was off...
I know it takes a day or two for a new rom to settle in but I certainly wouldn't think it would have that large of an impact

I read somewhere that there is/was a bug where after a reboot Google talk or maybe google+ launches the camera in the background which keeps running until you manually open the camera app and close it. I believe I read it some where on Franco's kernel post. Not sure if the bug is still there and if it's the culprit here, but might be worth investigating.

[Q] My awake time seems awful high, where do I go from here?

I picked up betterbatterstats as my battery life has been crappy over the past few days, I have found the following to be true: I am barely using the phone as I'm at work all day and the battery is draining much faster than before. My screen time is 20 minutes total for the following stats.

I'm not sure if I'm not using BetterBattery correctly but I can't find an option to tell me what offending processes are keeping the phone awake for so long. How do I figure out what is causing this?
Thanks for any help.
Check partial wakelocks in better battery stats.
Turn off your GPS. That is what worked for me. I have 9h 6m 20s on battery and Android OS only has 51m of awake time.
check your apps, if you're not using them, close them. ask yourself, what apps do i have installed that require wakelock permissions. those are the ones who will drive android os through the roof. latitude. maps. email. feeds. even games can trigger sensors and not let go of them properly, leaving your cpu always working. check cpuspy from market.
turn off autosync. you're working right? no point getting distracted over some lame ass post on fb or some worthless spam in your mailbox.
Ok, so now this is weird. I don't have any apps keeping the phone awake for very long, but the wake counts are retarded, take a look at the attachment. The time is very low, but the count is over 2k. The phone is at about a 75% wake time. This really doesn't make any sense.
