I usually use an app called Accbattery to monitor the discharging speed of my phone when I sleep. The hibernation normally can put my phone to a good sleep overnight for about 3%-5% power consumption per hour, I know it's not the greatest but it's an acceptable speed for me considering the battery conditions.
Recently the 'deep sleep' hours have been reduced to less than 1 hour overnight (the longer the deep sleep the less power consumption), even though I do not have any unusual App usage, the phone just doesn't sleep long enough.
Can anyone offer me some suggestions?
Thanks
