If your iPhone has been failing to charge past 100%, it’s time to take it to a Genius Bar. But if you’re not sure where to find one, here are some tips on how to fix an iPhone that won’t charge past 100%:

  1. Check the battery level: Make sure the battery is fully charged before trying to charge your iPhone. If it’s not, you’ll need to replace the battery.
  2. Charge in a quiet place: When charging your iPhone, make sure it’s in a quiet place so as not to disturb other people or animals nearby.
  3. Use a surge protector: If you’re using an outlet that doesn’t have surge protection, you may need to buy one. A surge protector will help protect your computer from overcharging and causing damage.
