iPhone 12 pro max barrery drain
Hi, Ive recently updated my iphone 12 pro max to ios16.1 and I'm facing severe battery drain issue. My device battery health is 90%. I can literally see my iphone battery draining (a decline of 1% in almost 2 minutes). Now I've to charge my phone 2 times a day with screen on time of approx 3.5-4 hours. If playing a video in speaker, it barely lasts 3 hours. I've followed almost every tips to reduce battery drain issues other than keyboard haptics, which is a personal essential. But even with the same settings, easily my phone used to last for a full day. Even without using for 6-8 hours there's a decline of 8-10%. Please help !!
