put your unnecessary apps in sleep mood or deep sleep mood. in battery section you just set a time for daily optimization mood on everyday, night time will be better, when u don't use your phone. atleast 3days auto restart at night time differ from the optimization time. if still don't solve the problem, then it's your mobile network and mobile data unstable problem by the operator. try to make cool the phone most of the time. hope it will be helpful.
Thanks alot for the information . But i hardly use applications in this mobile and yeah as you said there might be chances of unstable network from provider . Will look into this .
