iOS 18 Logo

iOS 18 introduces a new feature that allows users to set custom battery charging limits, giving them more control over their iPhone 15’s battery health. This feature lets users choose to cap charging at 80%, 85%, 90%, or 95%, which can extend the battery’s lifespan. The option is available in the Settings app under Battery, offering an easy way to manage battery health.

Apple’s latest update in iOS 18 is particularly useful for those looking to maintain their battery’s longevity. By preventing the battery from charging to its full capacity, users can avoid the wear and tear that comes with constant 100% charges. This feature is exclusive to the iPhone 15 lineup.

For iPhone 15 users, adjusting the battery charging limit in the Settings app is straightforward. Navigate to Battery, then to Charging, and select your preferred limit. This small change can make a big difference in how long your battery lasts over time.

Empowering Your iPhone’s Battery Health

Expanded Charging Limits

Unlike previous iOS versions, iOS 18 introduces a range of charging limits beyond the standard 80%. You can now choose from 85%, 90%, or 95%, offering greater flexibility in how you manage your iPhone’s battery health.

Optimized Battery Charging

While Optimized Battery Charging aims to extend your battery’s lifespan, it might not align with everyone’s charging habits. iOS 18 allows you to prioritize a full charge by disabling this feature when setting a lower charging limit.

Personalized Recommendations

iOS 18 goes a step further by offering personalized charging limit recommendations based on your usage patterns. This helps you strike a balance between battery longevity and convenience.

Temporary Override

If you need a full charge for a specific occasion, iOS 18 lets you temporarily override your chosen charging limit. You can easily revert to your preferred limit afterward.


This expanded feature is currently exclusive to iPhone 15 models, leaving older models with the existing 80% limit option.

Customizing Battery Charging Limits on iOS 18

iOS 18 introduces new features that give users greater control over their iPhone’s battery charging process. By allowing more flexibility in setting charge limits, users can improve battery life and health.

Understanding the New Charging Limit Feature

iOS 18 enables users to set specific charging limits on their iPhone 15 and other compatible models. Previously fixed at 80%, new options include 85%, 90%, and 95%. This feature is designed to help users maintain better battery health and extend their device’s lifespan.

Allowing users to stop charging at a lower percentage can reduce wear on the battery. This is especially useful for those who do not need a full charge daily.

How to Adjust Charging Limits via the Settings App

Adjusting the charging limits on iOS 18 is straightforward. Navigate to the Settings app, then select Battery.

You will find the charging limit options under Battery Health & Charging. Here, you can choose your preferred limit: 80%, 85%, 90%, 95%, or 100%. By selecting a lower limit, you can help preserve your battery’s health over time.

These changes apply immediately, so users can easily switch limits based on their daily needs.

Compatibility and Availability

The new charging limit feature is available on iPhone 15 models running iOS 18. This includes iPhone 15, iPhone 15 Pro, and any newer models.

Older models like the iPhone 14 and iPhone 14 Pro do not currently support these granular charging limits. Users of these devices may need to upgrade to benefit from these enhancements.

iOS 18 will be available for download later this year, ensuring many users can access this feature.

Impact on Battery Health and Longevity

Limiting the maximum charge helps in maintaining battery health. Frequently charging to 100% can degrade the battery more quickly.

By setting a lower charge limit, users can reduce the stress on their battery. This can ultimately result in a longer-lasting battery and better performance. Users who often leave their device plugged in can benefit significantly.

Overall, customizing charging limits helps in optimizing the battery’s longevity and performance with minimal effort.

Advancements and Supporting Features

The integration of new charging limit options in iOS 18 for iPhone 15 models brings significant improvements. It connects well with the entire Apple ecosystem and enhances user experience with intuitive interface changes.

Integrations with Apple Ecosystem

iOS 18’s charging limit options are designed to work seamlessly with other Apple features. By ensuring the iPhone battery stays at optimal levels, it improves the performance of Apple Wallet, Apple Pay, and Apple Cash. This means greater reliability for event tickets, notification management, and contact photos.

CarPlay also benefits because a well-maintained battery ensures uninterrupted connection. The integration extends to Siri and vocal shortcuts, which now respond more quickly without battery concerns. These developments were highlighted during WWDC 2024 and are available in the public beta, enhancing the overall Apple ecosystem experience.

User Experience and Interface Enhancements

The updated Settings app now includes a dedicated Charging section, offering a more user-friendly interface. Users can adjust charging limits with a simple slider, choosing from 80%, 85%, 90%, 95%, or 100%. This flexibility helps preserve battery life and gives users control over their device.

The streamlined design helps users navigate through options quickly. Beta testing showed positive feedback, marking a significant improvement from previous versions. These changes demonstrate Apple’s commitment to user-focused design, making iOS 18 both powerful and easy to use.
