Gmail doesn't even show up in my battery at all and it is always synched. I don't know what would be causing your 2-5% battery drain from it.

 

I'm having the same problem on my AT&T GS3 running JB. I recently noticed that Gmail is having the exact same behavior you describe. The only way I am able to avoid it is by backing out of the app rather than using the home button to exit. I've found that Gmail will continue to run in the background from around 2 to 5% until I kill it. I even tried leaving the process running without killing it over night (while plugged in) and it was still running when I woke up.

Have you found a solution?

 

% of cpu use and % of battery use are usualy very different things remember :thumbup:

 

That does seem a lot mate. Have you used Cpu Spy to see if its waking your phone more than it should while its asleep?

 

In an earlier post I said that removing the most recent update to gmail fixed the problem, but I was mistaken. The same behavior happens even after deleting the app's cache and data, and downgrading to the factory version of the app.

Also, I found that I had a titanium backup of the app from last November, so I tried restoring it and it still exhibited the same behavior.

 

Mine idles at 0% with an occasional spike. Wonder if this is a factory reset moment

 

That might be a good idea. I've never done a factory reset though. Forgive me if this is a silly question, but to what extent should I back things up to restore the phone after the reset? Would it be wisest to simply reinstall everything manually?

 

After the reset, when you boot the phone and log in, it should give you the option to download every app you had on it so if youre on a limited plan, obviously use wifi.
(Im not sure if that option even works without wifi tbh)

 

Thanks. I also read the post linked to in SUroot's signature and I think I'm going to go ahead and try the factory reset.

I'll post back with results.

 

SU is one of the forum's true fonts of knowledge mate so without doubt, that is the way to go man :thumbup:

 

I just finished a factory reset and it made no change.

 

It may be a bug in your release then. Keep an eye on it and see if ot causes any battery drain.

 

I've still not got the issue, if thats what you mean?!

 

I was answering the "Are others faring better" part, to which my answer is yes.

I have indeed read the entire thread before, as you can probably tell.

Google updates to gmail probably wont fix it because if it was a bug with gmail, we'd all have it. It's more likely a bug with your update to jellybean.

I still haven't seen you mention whether you've done a factory reset or not, because if you haven't, you should do that if even to rule it out.

 

Agreed. Id either just put up with it or back up what i can and factory reset :thumbup:
