How to set iPhone 15 battery charge limit to 80%

Enable 80% Charging Limit on iPhone

This feature is only available on all models of the iPhone 15 series.

New 80% Limit Charging Optimization feature stops charging when iPhone reaches 80% of full capacity. Don't confuse and confuse this option with optimizing battery charging. We've explained the difference between these two features below. It's worth noting that even with the 80% charge limit enabled, your iPhone will occasionally charge to 100% to maintain an accurate battery state estimate.

Here's how to find the new charging limit option on the iPhone 15 series:

• Open the Settings app on iPhone 15.
• Scroll down a little and tap Battery.
• Here, tap Battery Health and Charging

• Next, tap chargeoptimization.
• Finally, select the 80% limit option.

Difference between Optimize Battery Charging and 80% Limit Options

80% Limit and Optimize Battery Charging are two different battery health and charging settings. Optimized Battery Charging learns from a user's daily charging habits and delays charging beyond 80 until a more appropriate time when the iPhone is connected to a charger for an extended period of time. The iPhone eventually charges to 100%, it just takes longer. This is done to minimize the time the battery must remain fully charged.

On the other hand, when the 80% limit charging function is enabled, the iPhone will stop charging above 80%. That said, this rule doesn't apply all the time. Sometimes, your iPhone will charge to 100% to maintain an accurate battery state-of-charge estimate. As expected from optimizing battery charging, the tight 80% limit improves battery life by reducing extreme thermal stress.

With the new 80% charging limit, you don’t have to actively monitor the charging process. Your iPhone will automatically stop charging after age 80 to preserve battery health. This is a useful feature for users who like to maintain a 40 to 80 percent charge cycle and don't want to charge their iPhone beyond 80 percent unless needed.

How to Check iPhone Battery Cycle Count

The battery cycle count feature is only available on all models of the iPhone 15 series.

In addition to the new charging options, all iPhone 15 models have a dedicated Battery section in the Settings app that shows you additional details about your battery health. One of the most useful features is the ability to check the number of battery cycles on your iPhone 15.

For reference, the battery cycle count is the number of times you discharge and charge the battery. A cycle is counted when your iPhone charges from o to 100%. Previously, you could only check the cycle count on your iPhone using a third-party app or using developer mode. But now, the option to check the battery cycle count is available as part of iOS and is only available for iPhone 15 models.

Here's how to check the battery cycle count on your iPhone:

• Open the Settings app on your iPhone and visit the General section.
• Then, click About.
• Scroll down and you will see "Cycle Count" in the "Battery" section.
