My battery is draining quite rapidly since latest update. Would it be better to erase completely and restore to factory settings to set up as a new iPhone or what else. Battery health is at 85%. Would appreciate any assistance thank you.
iPhone XS Max, iOS 15
Apple won’t replace the battery until it reaches 80% capacity.

Thank you very much but I believe it was a rogue app. I wasn’t concerned about replacing the battery. I’m aware of the battery protocol etc,. My question was about doing a restore or setting the phone up again as a new device to knock out everything and start anew.
