iPhone SE 3rd gen battery drain on simple alerts
I have an iPhone SE Gen 3, purchased in September, that behaved perfectly until March of this year (no weird battery usage). I've been to the Apple store 3 times and while all techs have said the behavior is odd, there is nothing they can do since the battery health is still 100% and the battery usage is linear, not dramatically dropping. Problem is... I get a text, battery goes down 1-2%, Ring doorbbell notification, same. Scam call notification, 1-2% battery usage. To me, this is not normal. I've disabled all notifications I can. The Apple support line is dismissive and has only offered for me to send it to them for testing. I cannot be without my phone for time this will take. At this point, I have a text/call phone as using any app (Safari, Facebook, etc.) uses far too much battery. Any suggestions?
