#Wrong battery cycles and amperage

I have replaced battery in iPhone 8 in September 2025 and since then app NiceBattery is not showing right informations about amperage and battery cycles. Cycles stays on 0 since replacement and amperage moves between cca 280 mA (not using and not charging) and 350 mA charging (which of course cannot be real). It does not show any other values at all. On any other device it works. Also other iPhone 8 charging normally goes over 2000 mA and not charging maybe -8mA. I add screenshots from problematic iPhone. I was also re-test battery when I had replaced it and they performed 3 hour test and said everything is fine with battery. I did not told them about JB because they will not even test it under warranty. What could cause this issue about battery information? Thanks

No, not by apple but I changed battery in past in other device with not original one (not even official service but only a man doing it himself at his home) and it stopped showing battery health after few hours but info about battery still worked.

This device shows battery health but other things in pictures in OP not
