You need to do a factory reset bad. It will drop that android os down quite significantly

I have already done a factory reset. I did it last week after I received ICS.

Do you have lookout installed on your device or any non trusted apps downloaded?

**wkufan92** · 07-24-2012, 07:37 PM

No, I do not have lookout or any non trusted apps.

**mythstery** · 07-24-2012, 07:41 PM

My android os was above 50% after one reset, above 30% after the second and now has not gone above 20% after my 3rd reset.

**wkufan92** · 07-24-2012, 07:42 PM

Sounds like you guys think I should do another reset. So frustrating....

I was having battery problems when ICS came out for the t989 so I started using the darkside rom for like a month. last week I went back to stock ICS and My battery life is fine. It's as good as it ever was with GB and that's with a stock battery. I'm going to look into getting a 3800 mah battery. I had one of those big boys on my G1 back in the day. Looks funny but man. I'd go 3-4 days without charging sometimes...

That was my point. Why post in the sprint forum.

My battery life hasn't changed. Still a good 8 hrs on the factory battery.

Ok, trying to determine if I really do have a problem. Gut feeling says yes. Here are my results this morning with little to no use of the phone. I can't attach the pic for some crazy reason since I am at the office.

2 hrs 15 min of discharging - Battery 92% - I think this sounds pretty good but !!!!!!!!!!

Android OS - 67% !!!!!! Anyone else think that is way too high with the phone not being used?

After OTA battery life good for 17 hours (2500mah). This morning on battery using my E4GT nonstop 3 hours...see pic.

This is more what I would expect. That looks good.

But the post above and myself, still have way too much OS use. Something is causing it to just spin its wheels in the background on our phones.

I agree with the SD card being the problem.
I took it out last night took all my pics etc, formatted it to the phone and reset the phone. Then re-added my pics and music.
This morning everything seems to be running great (see pics) as you can see the phone is getting into deep sleep and in almost 4 hours and the battery hasn't even dropped 15% yet
I might also add I went back to using the original Samsung charger (was using an apple charger, the actual piece you plug in the wall) that come with the phone, the charge is slower but it might have helped as well.
The Android OS is still high but its no 60%+ anymore.

Here's mine. Android OS uses more than 50% but I still get amazing battery life.

**matt3166** · 07-26-2012, 12:57 PM

Are you rooted? Extended battery?

Android OS will always be the highest % if the phone is idle most of the time, which seems to be the situation in your case with that screenshot. Your AOS at 50% is perfectly normal, as you can tell from your excellent battery life. If you have about 2 hours or more of screen on time, the screen will always be the highest, assuming your phone is operating normally. If you have a rogue app or some other issue that is cranking the OS, Android OS may still be abnormally high.

The stock battery graph is good for displaying a particular user experience, but it's not very good at diagnosing a problem. One of the first things I do to diagnose battery issues is to install a free App called CPU Spy. CPU Spy will help identify periods where your phone is not entering "Deep Sleep" when it should be. Then, you can use battery diagnostics programs like Better Battery Stats or Badass Battery Monitor to try to find the culprit.

Found the culprit for mine. Wifi wasn't sleeping. Changed it in settings. Battery seems normal for now.

**treotimAC** · 07-26-2012, 03:16 PM

Apps are the primary reason for the increased battery drain. A factory reset should work if you don't restore your apps from a backup. The other option is to selectively delete apps that are likely to be heavy users of OS background processes. ICS seems to have enabled apps to use more background processing than previously in GB. That's why the OS percentage appears high relative to GB.

Nope. Not rooted with stock battery.

Yes that's what I thought. The screenshot was from when I didn't use the phone a lot. I figured if I played a lot of games or did a bunch of other stuff the % of Android OS will go down.
With regular use it can still last at least 24 hours which is still pretty good. Before the update I could only get 19 hours at most.
