You can test each new component one by one to see if it solves the charging problem for you. If your iPhone is able to charge more than 80% easily with a new charger, then you may be facing a problem with your old charger.

Higher ambient temperatures can interfere with iPhone charging, especially if the iPhone overheats. In this case, your iPhone will charge to 80% without any problem.

Over time, your iPhone often heats up while charging, affecting its overall temperature. So, if your iPhone still refuses to charge beyond 80%, then we now recommend that you remove the protective case of your iPhone, place it on a cool surface like a stone, preferably in the kitchen, and let it charge for some time .

To restart your iPhone, simply use it until your iPhone's battery drops to 0%. Once this happens, wait approximately 30 minutes and then press and hold the Sleep/Wake button again.
