Incorrect battery percentage readings on iPhone after battery replacement
I changed my iPhone battery a month ago. From the first use, the battery reading has been incorrect. When I charge it, while it’s connected to the charger and I check the charge level, it might show, for example, 76%, but in the battery section, it shows 89%.
The second problem is that after charging, if I turn it off and on, the battery percentage changes—for example, it was 80% and then becomes 84%. Even if I don’t use the iPhone, the battery decreases. I went back to the place where I changed the battery, and they said they did a repair and the battery is fine, but the problem still exists. What should I do?
