Auto-sync killing battery all of a sudden on S3? I have had my S3 for a good long while, ever since they were new with Verizon. Almost immediately, I bought an extended battery and all was good. In the last week or so, the battery has begun discharging rapidly. 50% in a couple of hours. I had extra batteries, so I switched out thinking I had a bad one. Same deal.

Looking around, I read that killing the cache should fix it. Nope. Then someone suggested turning off auto-sync. That did it. Battery drain want back to normal. Why? Why all of a sudden? Then, the Gmail app doesn’t want to manually sync… Annoying. I was hoping to avoid a factory reset, but would that be my next course of action? I’m wondering if the Gmail app is bad. Definitely going to dump that and re-install.

Any thoughts?
I hava a Samsung S5. Before I charged my phone once per 24 or 48 hours and since a few days suddently the battery lasted only 4 to 8 hours. After several test I discovered the cause was a few corrupt images. I deleted the corrupt images and the problem was solved. I used this app to find the corrupt images.
