How to Set iOS 18 Charge Limit?

Apple has introduced an advanced charging management feature called "iPhone Charging Limit" in iOS 18. This feature empowers users to set a maximum charge level for their iPhones, choosing from options of 80%, 85%, 90%, 95%, or 100%. With this flexibility, users can enhance battery longevity while managing their charging preferences.

What is the iOS 18 Charging Limit Feature?

The Charging Limit feature is designed to extend battery life and reduce degradation by allowing users to select their preferred maximum charge level. This is particularly beneficial for those who charge their devices for extended periods, as it helps mitigate the risks associated with keeping batteries at full capacity.

Differences Between Charging Limit and Optimized Battery Charging

The Charging Limit feature is a significant upgrade over the previously established "Optimized Battery Charging," which was limited to an 80% maximum for older models. The new charging limit offers more control and is available exclusively for iPhone 15 and newer devices running iOS 18.

Setting the Charging Limit

1System Requirements:

Models: iPhone 15, iPhone 16 series, and newer devices.

OS: Upgrade to iOS 18 or above.

2Steps to Set the Charging Limit:

• Open the Settings app.
• Navigate to Battery and tap on Charging.
• Customize your charging limit settings by selecting your preferred percentage.

Recommended Charging Percentages

When choosing your charging limit, consider the following:

• 80% Charging Limit: Ideal for maximizing battery lifespan, best for users who charge for long durations.
• 85% Charging Limit: A balanced option providing a bit more charge while still protecting the battery.
• 90% Charging Limit: Suitable for those who charge less frequently.
• 95% Charging Limit: Nearly full, best for users needing a quick charge before heading out.
• 100% Charging Limit: Traditional charging for heavy users who prioritize having a fully charged phone.

When to Choose 100% Charging Limit

For heavy users or those frequently on the go, setting the charging limit to 100% may be advantageous. During setup, users will be prompted to choose between temporary or long-term options:

• Allow Until Tomorrow: For users needing immediate power.
• Set Limit to 100%: For those who require a fully charged device regularly.

The feature also includes "Optimized Battery Settings," which uses machine learning to adapt to user habits, helping to preserve battery health.

Benefits of Setting an iPhone Charging Limit

• Extend Battery Life: Reduces battery aging by minimizing the time spent at full charge, decreasing the risk of swelling and capacity loss.
• Reduce Overcharging Risks: Prevents potential battery damage associated with prolonged full charges.
• Flexible Adjustments: Choose from various charging limits that best match your daily usage.

FAQs about iOS 18 Charge Limit

1Can I limit my iPhone charging to 80%?

Yes, you can limit your iPhone’s charging to 80% in iOS 17 and later, including on the iPhone 15 series. This feature helps prolong battery life by reducing charging stress when the battery is near full. You can enable the 80% limit in Settings, and the phone will stop charging once it reaches that percentage.

2Should I charge my iPhone to 80 or 100?

Charging your iPhone to 80% is generally better for long-term battery health. Lithium-ion batteries experience more stress when fully charged or drained. By limiting the charge to 80%, you reduce wear on the battery and extend its lifespan. However, if you need full capacity for a long day, charging to 100% can be practical. The choice depends on your usage needs and how much you want to prioritize battery longevity.

3How to stop phone charging at 80?

To stop your iPhone from charging past 80%, enable the "80% Limit" feature. Go to Settings > Battery > Battery Health & Charging, and toggle on 80% Limit. Additionally, using the Optimized Battery Charging feature can also limit charging to 80% during certain times to protect battery health. This feature is available on newer iPhones like the iPhone 16 and works automatically in certain conditions.

Conclusion

The iOS 18 charging limit feature empowers users to optimize their iPhone's battery life with customizable charging thresholds. By selecting the appropriate charging percentage, users can effectively balance convenience with battery health, enhancing overall device performance.
