For my hotmail and outlook account that I have connected to the Gmail app it gives me an option to select how often to sync, for my Gmail accounts, there's no option. This is especially annoying because I recently replacing my dying stock battery with the Anker 6440 mAH extended battery which is double the size yet I'm getting the same battery length. What do I do? Thanks!! ALSO i am rooted, on 5.1.1 and on OK1 firmware.
