How To Stop Battery Charging After 80% On iPhone?

To stop battery charging on your iPhone after 80% with iOS 13 or later versions, you can either turn off Optimized Battery Charging or use the 80% Limit option available on iPhone 15 models. Here's how to make these changes:

Turn off Optimized Battery Charging:

  1. Go to Settings > Battery.
  2. If you have an iPhone 14 or earlier, go to Battery Health & Charging.
  3. Turn off Optimized Battery Charging.

Use 80% Limit option on iPhone 15 models:

  1. Go to Settings > Battery > Battery Health & Charging > Charging Optimization.
  2. Select 80% Limit.

With the 80% Limit option enabled, your iPhone will charge up to about 80% and then stop. If the battery charge level gets down to 75%, charging will resume until your battery charge level reaches about 80% again. Keep in mind that occasionally the iPhone may charge to 100% to maintain accurate battery state-of-charge estimates.

Please note that turning off charging optimizations might increase wear on your battery and reduce its lifespan.
