Battery. Hardware of software issue?
After a month changing my battery, it still shows like these. Is it hardware or software issue?

Interesting. I just remembered I have a spare iPhone 6s. In the picture below, the top part where there’s a percentage is from iOS 12.1.1 and while the part with no percentage is after upgrading to iOS 13. Typical Apple, it’s so annoying.
Is this a good question?
