Why Your IPhone Stopped Charging At 80%

Regardless of broken and damaged screens, charging issues are among the most common issues iPhone users may encounter with their devices. That’s understandable because an iPhone battery — or any smartphone, for that matter — is one of the few components that naturally degrades over time. Time does its work and Apple batteries are no exception.

Why Your IPhone Stopped Charging At 80%

While you may have noticed that your iPhone doesn’t charge after 80%, you shouldn’t assume it’s time to replace it. There are several reasons why this happens, and most of them have easy solutions. Read on to find out why your iPhone stopped charging at 80% and what you can do to fix it.

Why does my iPhone stop charging at 80%?

If the iPhone stops charging at 80% only occasionally, it’s likely due to a feature Apple has implemented to extend the iPhone’s battery life. Apple introduced a battery optimization feature in iOS 13 that slows down the iPhone’s charging speed and even maintains a charge at 80% to prevent excessive battery drain.

That’s why your phone sometimes charges but stops at 80%.

Most of us try to keep our phones charged as much as possible, but it turns out that this can be detrimental to the iPhone’s battery.

For starters, charging and maintaining a full charge puts more demands on lithium batteries in smartphones, reducing their lifespan. Not to mention that overcharging the phone overnight causes the battery to heat up, shortening its lifespan.

Battery life is related to chemical life, which is longer than the period of time since the battery was assembled. A battery’s chemical life is caused by a complex combination of several factors, including temperature history and charge pattern. All rechargeable batteries ​​are consumable components, their efficiency decreases over time, and they are chemically obsolete. Li-ion batteries chemically age over time, so their charge capacity decreases, resulting in shorter battery life and lower peak performance.

How to disable optimized battery charging on iPhone

With iOS 13 and later, Optimized Battery Charging is designed to reduce battery drain and extend battery life by reducing the time iPhone is fully charged. When the feature is turned on, iPhone delays charging after 80% in certain situations. iPhone uses on-device machine learning to understand the daily charging pattern, so battery-optimized charging is only enabled when iPhone expects to be connected to a charger for an extended period of time. This algorithm aims to ensure that the iPhone is kept fully charged when disconnected.

If you are using iOS 13, the Enhanced Battery Charging feature will be enabled on your iPhone by default. If you prefer to charge your phone up to 100%, you can easily disable this feature in the battery settings.

To turn off advanced battery charging, go to Settings > Battery > Battery Status and disable advanced battery charging. You will see two options: Shutdown until tomorrow or Turn off (permanently). Choose what you prefer.

Battery saving

Understanding what affects your iPhone’s battery life is the first step in making it last longer! Keeping the charging tips in this article in mind and using high-quality iPhone chargers will give your battery the longest possible life.
