I charged my phone to 100% before going to sleep and when I got up the battery was down to 65%... When I checked the power usage, the Android system was consuming over 60%....I wiped the cache and data and reset my phone....again the Android system is consuming more than 45%.... without any apps....the battery usage also shows "Awake" all the time when the screen is off and also I have enabled screen lock.... please help!!!
trust it's the apps. MIUI fails to show correctly which app used how much battery. Remove unnecessary apps and battery will improve drastically. I removed few apps including airtel tv and that has increased my battery backup more than two folds. Plus I never ever used airtel tv.
