I have a IPhone 14 Pro Max. I would be watching Netflix in the morning after my phone has been charging all night and within a few hours I see my phone say 20% remaining then 10% in 5-10 minutes then dies. Once it turns back on from charging it says 50% so I unplug it after a few minutes so now it’s at 55% then dies again at 52%. Looked into my battery settings at says my battery health is at 85%. What’s going on?
iPhone 14 Pro Max, iOS 17
Your battery is failing. There is likely a message on the battery health screen that says that battery performance is impaired. There is more than just battery capacity decreasing that can cause a battery to fail→iPhone Battery Repair & Replacement - Apple Support
