Just wondering if this will improve my battery life as I have synch turned off for everything but mail at present but still have battery issues. I had a fully charged battery last night, always check settings for running apps, used night mode in Battery Widget Reborn and found this the battery down to 78% with various games and Google Play running in the background, though they had been turned off and mediaserver at 80%. Now I had issues in the past with mediaserver, but thought that had been resolved by turning off Currents and keeping an eye on turning off apps I didn't want running in the background. Should I do another factory reset, or power off every night instead ?
