Android changes sleep interval to 30 minutes automatically - Galaxy S I9000 Q&A, Help & Troubleshooting

I can't figure out why it changes to 30 minutes several times a day. Is there a way to analyze the settings to see if one of my apps is causing this? Needless to say, it drains my battery unnecessarily.

Display malfunction

Hi guys,
Maybe some of you have experienced this before, when I put my note away the screen of it gets lit up as if there was an app keeping it from sleep mode. But this happens even right after I have terminated all apps and processes. So technically barely anything runs. I think it might be a software issue? Any ideas please?

Install the CPU spy.apk (Play Market). This app will tell you if your phone is in deep sleep.
can u post the battery stats
open your battery, wait 10 seconds, reassemble and turn it back on... if you're still facing the problem, install and run CPU Spy from Play Store and see which app/service is keeping you phone from sleeping and uninstall that.
It's probably a kernel wakelock
Will try the CPU spy application now. Will post my findings.

Should I be looking at these processes that are possibly waking my phone up? So far I don't see how this app is solving my problem.
Thanks so much

this l2_hsic wkelock is mainly caused by unplugging the charger without unlocking the lock screen. or unplugging when the screen is black.
Its a known bug
shutdown ur phone., pull out battery, wait for 10 secs., reinsert and reboot. The wkelock should be gone. test again with betterbatterystats

See If you have suspend_backoff kernel wakeup i Better Battery Stats. If so - try uninstalling Chrome from your device.

none of these custom ROM are optimized for battery.. i have tried a couple of them..
you can give 'Easy battery saver' from google play a shot.. it is a good tool and can help you in optimizing the battery..
BTW what do you primarily use your phone for?

Not 5% for that short period of time.
Something is seriously wrong dude, download betterbatterystats and run it a bit and see what drains so much. Either your battery is bad or you have some app that drains a lot battery in background.
Can someone please guide me on how to use betterbatterystats?? I installed it but I don't know how to make it work :s

Go uninstall facebook.
it made my incredible S last like, 3 hours longer
and my nexus 7 battery life went from 3 days to 4 days
3.5 hours of screen on time is a lot, id say at almost lasting a whole day you're doing pretty well?

Battery drain

I'm having a problem with my phone not going into deep sleep, I've tried reboots and stopping background processes, it didn't help. Any ideas?

Try betterbatterystats from store then see what's actually happening behind the scenes.

Why are you complaining? You got more than 17 hours from only 35% battery loss! I get maybe 15 hours with 100% battery loss -_-
But to help your problem, install an app called greenify. It allows you to block certain apps from being active in the background.
I usually lose about 5% tho after 12 hours with everything off

I'm getting 25% drain after about 9 hours of deep sleep on the newest Slimbeaan 4.1 release. I seem to remember only having 5-10% drain overnight on the first few builds. Is my battery dying or is it the newer builds?

Are you sure you mean 4.1 or 4.2 which has recently been released? The battery drain on 4.2 ROMs is an issue right now, although 4.1 isn't a whole lot better either.

I switched onto the 4.2 bandwagon a while ago and just recently reverted back to Slimbean 4.1 as I had remembered having great battery life on it. But after flashing and using for a few days, it's really not that much better. I still lose about 20-25% overnight on both 4.2 and 4.1 on the stock battery.
Well I just noticed something, it clearly says 17 hours, I assume on a 1+ year old battery am I correct? If so, then why are you complaining!!! Lmao you have Fantastic battery life!!!!

17 hours?
I'd be interested to know what ROM, etc. the OP is using to get 17+ hours of battery life out of this phone. Is it an extended battery? I'm getting pretty poor batter life after recently switching from Peach to Slimbean 4.1.2. Greenify seems to help.

If you have noticed, most people with good battery life seem not to use the phone to make calls. I think searching for a network drains the battery

With omniswitch activated my battery stands at least 24h,,,but when i accidently put it off,,,my battery suddenly stands 48 h and the phone consumed only 45% in 24 hours.Is this convincing enough!!! And by the way,the using mode is the same in both cases.

In many cases that's pure coincidence.
I mean - do you see it appearing in battery stats?
It's pretty much impossible for an app that doesn't hold wakelocks to have any significant effect on battery life.
