Battery charges fine but battery level indicator is stuck. Why?
Hello,
Strange thing happened to my iPhone SE. I bough this phone second hand, I have replaced its battery once (back in February 2019) with an aftermarket one and I believe the replaced was still the factory one.
It was working all fine until a couple of days ago I removed it from the charger in the morning after an all night charge to see that the phone only shows 36%. Charging is fine, battery life is normal, it’s just the indicator is stuck at the point where the last charging cycle began. The day before I started to charge it at 16%. Charged up full (I guess), still firmly showing 16% and let it drop to 6% (took the whole day). Now it is stuck at 6%. See attachment for battery diagram. Simply put, the battery level indicator won’t ever increase, it can only decrease.
As I mentioned, there is no problem with the battery life. My only problem is that I don’t see the actual battery charge level.
I haven’t touched the logic board since the battery replacement, didn’t mechanically knock off ICs and I don’t recall dropping my phone or exposing it to water.
By the way, when I knocked of an IC from around the battery socket of my previous iPhone 5S, it didn’t charge, but showed charging symbol at firm 1%. So that issue was different because this is charging.
Tried playing with the time-zone settings (toggle automatic), didn’t work.
Tried soft-reset, didn’t work.
Updated to iOS 13.1.2, didn’t solve the issue either.
Do you know what the problem might be?
If I should try replacing the battery, what is the brand you would recommend?
Thanks in advance.
Best,
Tamas
