My Iphone 6s is draining the battery at an alarming rate.
Since updating a few days ago Iphone is draining battery really fast for no reason. Have turned off all notifications etc. and still going on. I use my Ipad and it is linked so turned off a lot of things on that too. What is causing this, I have had the Ipad for 3 months and it never caused this before. Help someone, this is ridiculous.
iPhone 6s, iOS 11.4
