My 'Android System' and 'Android OS' draining 40% of used battery.

[Android Central Question]

My mobile randomly switches off and on automatically once in a day. Also it gets cooled while charging normally(not fast)

I have used:
safe mode
Greenify App (as usual)
Aeroplane mode (as usual)
Used developer options of killing background processes of apps, etc.
Cleared cache memory of various running system apps and processes, even force stopped and disabled them
Blocked all syn, updates etc.

40% of what? If that's 40% of a total of 5% drain, that's nothing. If it's 40% of 75% drain, there's something wrong.

Register, then fully charge the battery. Use it until it's down to about 50%, then take a few screen shots of Setting > Battery, showing us total drain and what's using how much (see How To Post Screenshots on Android Central). Seeing the phone idle or phone standby will also tell us something.

Welcome to Android Central! Which phone? Is it rooted, running a custom ROM? Is the battery life actually decreased, or is it lasting the usual amount, but you now notice an increased percentage of use by Android System and OS?
