With time the battery of your iPhone 8 Plus will be less efficient which will imply a decrease of autonomy. You will not have the choice to have it replaced if you want to find a phone that holds the charge. The charging time of your iPhone seems too long to be done; you have to wait longer than usual for it to be recharged. You have put your iphone in charge but it refuses to recharge, you have changed charger but the problem does not come from there.
Repair your iphone battery when:
- Battery is emptying too fast
- Loading too slow
- Impossible charge
- Reloaded phone does not turn on anymore
- Burning battery
