Why you should only charge your iPhone battery to 80%

Most of us try to charge our iPhones as much as possible, but this will cause lithium-ion batteries to degrade faster as they become more unbalanced.

In other words, the longer your iPhone battery is fully charged or drained, the less charge it will have. If you charge your phone overnight, it will stay at 100% charge for hours on end. This will accelerate the aging process of the battery.

To fix this, Optimized Battery Charging on iPhone prevents your device from charging past 80%, helping to maintain your phone's battery health and prolong its lifespan.

The feature of limiting battery charging to 80% is integrated by Apple on the iPhone 15 generation.

On the iPhone 15 generation, Apple has integrated a feature that limits battery charging to 80%. The "bitten apple" is applying the 40-80 rule to increase the life of lithium-ion batteries.

According to Cultofmac , charging your iPhone battery at 40-80% capacity will give you the best battery life. This rule doesn't just apply to iPhones, but also applies to many other devices that use lithium-ion batteries.

To use this battery optimization feature on the iPhone 15 generation, users can access Settings -> Battery -> Battery & Charging Health -> Optimized Battery Charging -> Limit 80%.

However, limiting the iPhone battery charge capacity to 80% will also cause some inconvenience to users. First of all, you have lost 20% of the total battery capacity of the device.

For users with basic needs, this may not affect too much. But if users often use iPhone to play games, listen to music or watch videos , this iPhone battery optimization feature may cause your device to not have enough power to meet the needs of use.
