Aside from broken screens, charging issues are the most common problems that iPhone users face with their devices. This is understandable because the battery in your iPhone—or any smartphone, for that matter—is one of the few components that degrades naturally over time. Time does its thing, and iPhone batteries aren’t exempt from that.

Why Does My iPhone Stop Charging At 80%?
If your iPhone only stops charging at 80% sometimes, it’s most likely due to a feature Apple implemented to extend the life of your iPhone battery. Apple introduced a battery optimization feature in iOS 13 that slows down how your iPhone charging, and even holds it at 80% to prevent over stressing the battery.
That’s why your phone sometimes charges, but then stops at 80%.
Most of us try to keep our phones as charged as possible, but as it turns out, this can be detrimental to your iPhone’s battery.
For starters, charging to and maintaining a full charge is more demanding on lithium batteries in smartphones, shortening their lifespan. Not to mention that over charging your phone overnight causes the battery to heat up, which reduces its overall lifespan.
How to Turn Off Optimized Charging on Your iPhone
If you’re running iOS 13, the Optimized Battery Charging feature on your iPhone will be enabled by default. If you’d rather have your phone charge to 100%, you can easily disable this feature in the battery settings.
To turn off Optimized Battery Charging, go to Settings > Battery > Battery Health and toggle off Optimized Battery Charging. You’ll see two options: Turn Off Until Tomorrow or Turn Off (permanently). Choose whichever one you prefer.
