Iphone 16 battery drains super fast and overheats
So i've been using my iphone 16 since october 2024 and I have 71 cycles with it. I bought it brand new and in settings it says that the battery health is at 100%. Two days ago I used some sketchy looking wireless charger and after using it my phone started overheating and battery draining surprisingly fast. I tracked how long it took for it to drain 10% whilst doing usual stuff like writing messages, looking at videos n such and it only took 23 minutes. Idk it may be normal but I don't think so. Any help?
iPhone 16, iOS 18
