iPhone 12 Pro Max battery drain.

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 .

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%.
