One of the prominent selling points of the iPhone 13 lineup is its long battery life. That’s true; your iPhone 13 can give you up to 2.5 hours of extra use in comparison to its predecessor. So, it’s normal to wonder how to take care of its battery, especially if you want it to serve you for a long time to come. And with that said, we’ll help you uncover what happens if you keep your iPhone 13 charging after 100% - so make sure to join us.

The following applies to all models of the iPhone 13 lineup. However, the same also applies to previous iPhone generations, especially those capable of running iOS 15. 

What Happens If You Keep Your iPhone 13 Charging After 100%? 

Once your iPhone 13 charges up to 100% (once it reaches its full charge), it will protect its battery from overcharging by preventing additional energy from reaching it. In other words, your iPhone 13 comes with incredibly intelligent internals, capable of making adjustments to how your phone charges. Those come as measures to preserve your device’s battery and ensure that its health stays intact for a long time. 

One of those measures/features is called 'Optimized Battery Charging' and should be enabled while setting up your iPhone 13. However, you can enable or disable this feature manually by navigating to Settings > Battery > Battery Health > Optimized Battery Charging.

With that feature enabled, your iPhone 13 will learn your usage habits and adjust its behavior to prevent the device itself from reaching 100% in one go. In other words, your phone will charge up to 80% of its total capacity, using the fastest available type of charging. After that, the 'Optimized Battery Charging' feature will kick in, using on-device machine learning to charge your phone in small increments, which avoids overcharging, overheating, and harming your battery’s chemical age.

With that said, nothing really happens if you keep your iPhone 13 charging after 100% - as your phone will prevent additional energy from harming its battery. Consequentially, you’re free to charge your iPhone 13 overnight, as well as use your iPhone 13 while charging.
