Hello, Im currently tired of commenting, asking, and seeing this issue all over the place. I dont really know what is happening in Apple but it seems that Battery is not getting fixed anytime soon. My iphone 7 is about 1 year old, and since ios 11 I get quick drains of battery (about 10%) within minutes of use. Sadly I thought that this was getting fixed on iOS 11.3.1 but it keeps heating up a lot and then theres the drain. Battery health apparently 86% which is quite fair, but I dont really think it reflects its performance. Also im afraid about damaging the battery when the phone heats up while using safari or just texting someone.
