Try soft reset by pressing vol dn + power btn together till u feel a vibration n see Nokia boot logo

Try disabling some background apps in battery saver apps....

If none work hard reset settings -> about phone -> reset my phone..

Take backup before performing hard reset... Soft reset won't delete ur data but hard reset will!
