After New battery replacement,
My device is iphone 8 plus ios 13 , after new battery replacement the important battery message appearing, in YouTube one of the guy told that in iphone 5-8p if ios degrade to 11 or lower the message will not appear like that he told. Please suggest if doing that will help, or I should buy a jcv1s to copy and write.
