Ok so I've been experiencing the android.system drain since my first GS3 around August 5thish. I had to replace that one, but it still happens on the new device. With both phones I had amazing battery life the first few days, even with a bunch of apps installed. With the second, it did start after I restored most of my apps with Titanium Backup, though not immediately. This lead me to believe it was an app. So I went through, uninstalling random apps that I thought might be culprits, battery pull, nothing helped. So I gave up, started researching, then...out of nowhere, it's gone. And I'm back to amazing battery life. This carried over for a few days, without me not doing anything different or installing anything, and suddenly...it's back. Long story short, I don't think it's an app anymore, so much as a system setting, because the app "evidence" is so inconsistent, as evidenced by all these threads on it. Certain apps might "trigger" it, but the problem is deeper. So I messed with everything from GPS to wifi, using a live wall paper, even changing settings in both apps and stock...no change. But again...suddenly gone. Basically I couldn't pinpoint a common denominator except it happened randomly. Or so it seemed...
It happened again on Sunday night, and so I decided to see what happened. Only thing that really changed app wise were updates from the store. No change after those. Then I fell asleep Monday night without plugging my phone in, and android.system drained my battery to 3% from maybe 40ish%. I charge it for the 45 minutes I had before work, got it to like 49%, android.system still close to 25% in Gsam. Watchdog still showed nothing. Used a co-workers charger for a bit at work to make it through the night, finally drained it completely, did a battery pull, charged it to 100% while off, turned it on this morning...no problem. Been opening all kinds of apps today, changing settings...android.system is still around 4%, as opposed to being up to 50%. I found the gsiff_daemon solution, and I did have it at the top of the list, so I renamed it. No change. Deleted it. No change. Definitely gone though.
So now I think it's a battery issue. For those of you who experience it, did you happen to have unusual charging patterns around the time it started? Charging it for a few minutes here and there? Or draining it completely? So I'm thinking it has something to do with how the phone uses the right amount of power for what it's doing. When it's locked, it for some reason still thinks the phone is on and so is taking more power. And remember, as many changes as I could think of didn't help. So maybe it's happening in the hardware (however a phone determines power from a battery :blink
moreso than the software?
And sorry this post is so long, the idea was to show you I've already tried everything suggested and more (short of a FDR). One common denominator is all threads on the issue have the same suggestions and identical screen shots:icon_ devil:
Here are some screenshots I just took of what it SHOULD look like:
