I have a battery drain issue with a stock Nexus-7 (2013), Android 6.0.1, up to date with monthly patches. The battery is losing 15-20% overnight. Turning WiFi off overnight doesn't reduce it, or not much. The top consumer is just called "10017".
Some background - A recent version of Sygic Navigation was showing high battery usage even when I didn't use the app. I couldn't keep it from running. After exiting it, or after force-stopping it, I would shortly find it running again. I deleted the app but kept its user folder. Maybe related?
I keep Google Account Manager and Google Play Store disabled when I'm not actively using them. This is not new; I've done it since shortly after the tablet was new.
I installed the August patches a few days ago; the tablet was rebooted by that process. The battery issue predates that update.
How can I find out what it (10017) is?
