iPhone 8 unable to determine battery health

I recently bought an iPhone 8 that needed a new battery. I replaced the battery (from mobilesentrix.com) and it showed the battery health once and now whenever the phone is powered on the battery meter shows 1% remaining and in settings it says "Unable to determine battery health" in settings. Do I need to buy a new battery or is it something else? Thanks.

i've heard this was an issue with SE2020's, but not the 8 - i could be wrong.

supposedly the solution is to use a reprogrammer like JC V1SE to give the newbattery the SN/ID of the old battery so IOS thinks it's the one that was installed at the factory. not sure if there's an easy fix if you don't have a reprogrammer.

Hi

I have had this issue with the iPhone 6S and I found reseating the connector sometimes works or just leaving it for a week or so

I have found each methods to work on different occasions:-)

Hopefully this helps

Any questions please ask

Thanks:-)
