Having battery drain issues on my iPhone 12 Pro Max on standby....no background app usage ...phone is always connected to WiFi no 5G..there is 15-20% battery drain overnight,,,even updating to iOS 14.3 doesn’t solve the issue..anyone got anything to share to optimise settings I’ve done everything on my part...or is it a wide spread problem with 12 series..posting both the images at 100% charge and @moring see the drain .
iPhone 12 Pro Max, iOS 14
I have an update here. Last night I changed my Mobile Data Option from 4G to 3G, turned on Low Data Mode, deleted the default Mail App of iOS and restarted my phone. These 3 changes were done after all the Battery Saving Tips on YouTube failed for me. To my surprise, I did not see even 1% battery drain overnight (7 hours of standby time) when the battery was charged >= 90% but lost only 4% overnight battery drain when the battery was charged somewhere around 75%.
Do what a half billion other users do:
Charge it while you sleep.
