IT WORKSI have a customer with a iPhone XR we did battery replacement but she upgrade to iOS 13 making any replacement battery nonfunctional would not charge up but synced to my pcI installed iphone 8 battery it charged all the way up may have lower mAh but same volts 1.79 pulling ampsIt works!We can beat apple and there schemes

iOS 13 doesn’t make the battery nonfunctional, but just tells the user to replace it., with a “Service”message under the battery health feature.

This doesnt work, i tried 2 ip8 batteries and both didnt boot
