There is nothing wrong with our iPhone and the charging circuit. The iPhone charges fast up to 80% and then the speed slows down for the balance of the 20% (total of 100%). This is part of the battery maintenance and longevity.


You probably also have Optimized Battery Charging set to ON. You can turn this setting to OFF if you want your battery charged straight to 100%. To do that, open Settings ➡️ Battery ➡️ Battery Health ➡️ Optimized Battery Charging: Set this to OFF.

It is normal for charging to slow down when it reaches 80% battery capacity. But this is really too slow. Try charging your phone with another original Apple cable. If the problem persists, turn off optimized charging. If that doesn't help either, I think there's a hardware problem and you probably need a warranty to accept the claim. Repairing at your own expense would probably not pay off at all with such an old phone.
