How to Turn Off Optimized Battery Charging
System Requirements
This tip works on iPhones running iOS 16 or later, but some of the steps below apply to only the iPhone 15 or newer. Find out how to update to the latest version of iOS.
What is Optimized Battery Charging? When this function is enabled, your iPhone will delay charging past 80% in certain situations. This is recommended for improved battery life, since it will prevent your battery from degrading faster. If you are wondering how to keep your battery healthy on iPhone, my first recommendation would be to leave Optimized Battery Charging enabled. However, in situations where you need your iPhone to be charged to full quickly, temporarily enabling it is an option.

- Open the Settings app, and scroll down and tap on Battery.
- If you are using an iPhone 15 or newer, you will have two options here. If you are using an iPhone 14 or older, please skip to step 4. Otherwise, tap Charging Optimization.
- Select either 80% Limit or None. 80% Limit will make it so that your iPhone only charges to 80% and stops. This can help preserve the battery. If you want your iPhone to always charge 100% with no delay, select None.
- If you are using an iPhone 14 or older, tap Battery Health & Charging.
- Tap the Optimized Battery Charging toggle to turn it off. Green means optimized charging is on, gray means it's turned off.
- Select Turn Off Until Tomorrow or Turn Off, whichever you prefer. Turn Off will keep charging optimization off until you turn it back on again.
Once you make a selection, your changes will save automatically. If you decide to turn Optimized Battery Charging on again, you can enable it again as necessary using these same steps.
