So with iOS 11.3.1 release all non genuine batteries (and it appears genuine ones are sometimes affected) no longer show battery usage information
I asked a few retailers if they could tell me if their batteries would work with iOS 11.3.1
Here is a reply I got from one seller.
"Hi mate,
i have been told , my batteries can be updated firmware in 2 weeks, if you message me in 2 weeks, it will be compatible to iOS 11.3 version."
Is it likely Apple will rectify this issue in the next iOS update?
I contacted Apple myself but they refused to answer. Instead asking me to do data log procedures for them to investigate the issue.
