Hmm, not sure if the data in the article is correct. I replaced the battery in my SE 2020, there is no persistent warning, but i can no longer check battery health
Yeah, I’ve been replacing parts on and repairing iPhones for 15 years now; more of a hobby and fixing stuff for friends.
The battery is simple to replace even on the newest phones. Sure there’s a warning about non apple part that will show up but eventually subside. And that is only if you don’t swap the BMS module from the original to the new one. Any reputable shop should know to do this and have the skills required to desolder and resolder 2 connections…
