Here’s Why Your iPhone Stops Charging at 80% 

If your iPhone stops charging at 80%, the Optimized Battery Charging feature that Apple introduced in iOS 13 is most likely at blame. It attempts to prevent overstressing the battery and so lengthen the battery life of your iPhone by limiting the charge to 80%.

• Extremely Hot

Normally, when your iPhone is charging, you should sense a minor increase in temperature. Other times, it can become excessively warm, which might shorten the life of the batteries. Your iPhone’s firmware can prohibit charging above 80% in order to increase lifespan.

• Charge Optimization of Batteries

Optimized Battery Charging is occasionally used by iOS 13 and later to reduce the pace of battery aging. It accomplishes this by minimizing the amount of time your iPhone is fully charged. Your iPhone employs machine learning to comprehend how you charge it and anticipate when you will need it to reach a full charge, which is usually beyond 80%. If this is the case, there isn’t much you can do to stop it from happening. However, you should be aware that optimal battery charging is only engaged when your iPhone anticipates that it will be plugged in for an extended period of time (for example, when you plug in at about 20%).

• Try switching between several cords, chargers, and wall outlets to find the source of the issue. Your phone’s bottom charging port may also need to be cleaned because of dust buildup.

How To Fix A Non-Charging iPhone Past 80%

2. Switch off iPhone’s optimised charging

If you are using iOS 13 or later, Optimized Battery Charging will be enabled by default on your iPhone.However, you can quickly disable this feature in the battery settings if you’d prefer to charge your iPhone to 100% every time.

Observe these steps to stop your iPhone from using optimised battery charging:

• Then click Battery Health under Settings.
• Turn off the optimised battery charging setting.
• Turn Off or Turn Off Until Tomorrow are your two alternatives (permanently).

• Avoid Letting Your iPhone Get to 0%

The ideal method for maintaining battery efficiency used to be to let your phone’s battery drop to 0% before charging it back to 100%. This used to be true, however the batteries in today’s smartphones behave very differently. The best operating range for the battery in your iPhone is between 20% and 90%. Try to keep as near to that range as you can to extend the battery life of your phone.

• Prevent High or Low Temperatures

Although controlling the temperatures your iPhone is exposed to because of the weather can be difficult, keeping your phone away from high temperatures will make its battery last longer.To avoid this, keep your phone out of the kitchen when you’re cooking, inside when you’re outside, in the shade when you drive, and out of your car when it’s hot outside.
