AT&T S6 battery

[Gary_Berg]

I've got a 64gb AT&T S6 which seems to spend a lot of time busy in Android System and Google Play Services. I'm seeing stuff like after 7.5 hrs (battery 57%) that Google Play Services has kept the CPU busy for 12.5 minutes and held it awake for 32min. Android System has consumed 53 minutes and kept awake 21 minutes. SOT is 42 minutes. Sometimes the power draw is enough to make the phone feel warm in my pocket, around 90-100F.

It just seems like it spends a lot of time in AS and Google Play Services even when I'm doing nothing with the device. They are almost always the highest drainers, but even though I use the device little it often ends up at 50-60% battery at the end of 12-14 hours. I usually have 2 bars of cell connection, GSAM says medium strength most of the time.

This phone was freshly set up about 3 weeks ago, and was updated with all OTAs before being factory reset for the last time. So no OTA installed since the last reset.

Since this is an AT&T phone I have no access to the "optimization" tools Samsung released.

I've already followed S6 optimization advice as far as disabling bloat and reducing power drain.

I'm looking for ideas as to how to figure out how to find what is causing the OS to drain power.

I have had 2 different S6's. One Verizon branded and now an unlocked one. My Verizon one could not hit 3 hours of screen on time and had the same issues yours is. I did a reset after updating and all the tips and tricks I could find and no luck

Sold it and got a factory unlocked version (G920i) and most problems went away. Still have to use battery saving tips because of my heavy usage but I get 3:30 minimum SoT to about 4:30 SoT. (4 hours is the norm) I don't know if it's just the carrier brands or some have good battery and some don't. My first one I sent to Samsung because they even said over the phone that my battery was not normal ( I never tested it when I got it back I sold it right away because I was using a tmobile sim in a Verizon branded phone I wasn't getting optimal use)

Those are almost always the top battery users behind screen usage. The device is syncing/communicating with Play services in the background. Do you happen to have a screen shot of the screen on stats? Taking a quick look, I don’t see anything unusual with the battery stats you are experiencing.

SOT was 42 minutes at that time. I guess it makes sense that background stuff is going to be high as I didn't use it much that day.

Here is some GSAM data from later that day. I restarted the phone about 4pm and put it on the charger for about 10 minutes after that:
