Battery "error" message following battery replacement on iphone XR.
Hi, my son's iphone XR battery definitely needs replacing (it's approx 78% capacity). If replacement with a non Apple battery, the battery health info is lost and this can only be overcome by either switching the bms board from the original battery to the new one. I did ring Apple Support and was told this message doesn't occur with a genuine Apple battery with no need to worry about the loss of battery health info. However I rang a local repair shop who said they use genuine Apple batteries and that message will still appear until the phone software is updated. Apple store can update the software immediately as they have immediate access to software. Other repairers can't as they dont so will be about 3-4 weeks before a software update is issued.
I honestly don't know who to believe any more so is there anyone out there with any experience of changing the XR battery with either an Apple or non Apple battery and what happened with any resulting "non Apple component/battery health not available" info as a result.
Any advice would be much appreciated .... thank you for reading.
iPhone 6s, iOS 15
