Google Play Store accounts for over 50% of battery use! Solutions? Google Play Store alone accounts for 52% of my phone's battery use!

I would think Google Play Store would only run when downloading or updating apps, or when checking if apps need updated. Since last unplugging, I haven't manually run Google Play Store, nor have any apps been automatically updated.

Clicking through reveals that Google Play Store has been continuously requesting GPS. But I always have my GPS off in system settings.

I have all the sync settings off too. I don't want autosync.

So why is Google Play Store running uncommanded in the first place, and moreover, why is it using so much battery? How do I correct this?

Phone is LG G3 D855, Android version 4.4.2 KitKat. Rooted w/ xposed framework installed.



Things I tried:

I pressed the "stop" button in the above screenshot, which force-stopped the Google Play Store. But then many system services started shutting down and prompting me with "not responding" dialogs, until I eventually pulled the battery and restarted the phone.

I used SystemCleanup to disable several autoruns (such as receivers) for Google Play Store, so that it won't be constantly called on to run. I also killed the task using SystemCleanup (which did not kill the system).
Please delete the Google Play data and login again. Update the GP if neccessary. Let this time autosync GP till all is synced and now you can disable the sync of GP only. I guess it won't use much anymore then.
