Question: Battery concerns since last update
Since the last update my battery is draining at incredible speeds. I haven't added any other new apps, have turned off as much background running as possible. Before the update my 6s was working just fine. It says the battery is at 87% and supporting "peak performance" but essentially I need to have it plugged into an external source all day long. Any other suggestions?
iPhone 6s, iOS 11.3
