My Samsung s7 edge phone is 1.5 years old. For last 10 days experiencing battery drain issue. Hav e also tried power saving mode but it makes a difference of 2hrs. Battery drains in 1 hour. Have tried hardware testing, it was ok. Have unistalled less used apps. Have also followed Samsung ream standard faq Web page.
if you are heavy user then the battery will drain like this only i get 17 hrs backup but i dont use too much so its normal or take your mobile to service centre they will solve by sofware if there is any issue of software
