Charging Your iPhone to 80% (or Desired Level) to Preserve Battery Life

Preserving your iPhone's battery life is essential for long-term performance. Charging your iPhone to a lower level, like 80%, can help extend its battery lifespan. In this comprehensive guide, we'll walk you through the steps to charge your iPhone to 80% (or your preferred level) while minimizing wear on the battery.

Note: These steps require manual intervention as there is no built-in feature for limiting charging to a specific percentage. You will need to monitor your charging process.

Part 1: Enabling Optimized Battery Charging

iOS includes a feature called "Optimized Battery Charging" that learns your daily charging habits and tries to prevent your battery from reaching 100% until it anticipates you need to use your device. While it doesn't allow you to set a specific percentage like 80%, it can help reduce the time your device spends at maximum charge.

Open Settings:

Launch the "Settings" app on your iPhone.

Go to "Battery":

Scroll down and tap on "Battery."

Battery Health:

Tap "Battery Health."

Enable Optimized Battery Charging:

Toggle on the "Optimized Battery Charging" switch.

Part 2: Manual Charging to 80% (or Your Desired Level)

To manually charge your iPhone to 80% (or your preferred level), follow these steps:

Plug in Your Charger:

Connect your iPhone to a charger, either using a wall adapter or a computer USB port.

Charge Until Desired Level:

Monitor your phone's battery percentage as it charges. You can do this by swiping down from the top right (on iPhone X or later) or by checking the battery icon on your home screen.

Unplug at Desired Percentage:

Once your iPhone reaches the desired percentage (e.g., 80%), unplug it from the charger.

Avoid Overcharging:

Avoid leaving your iPhone plugged in once it reaches the desired level. Unplugging it helps prevent overcharging, which can cause additional wear on the battery.

Regularly Monitor and Charge:

Continue to monitor your battery percentage during daily use. When it drops to a level that suits your needs (e.g., 40-50%), you can plug it back in for a top-up charge.

Part 3: Tips for Preserving Battery Health

In addition to charging to your desired percentage, here are some additional tips to help preserve your iPhone's battery health:

Avoid Extreme Temperatures: Keep your iPhone at temperatures between 32F and 95F for optimal battery performance.

Use Genuine Chargers: Use Apple-certified chargers and cables to avoid damage to your battery.

Regularly Update iOS: Keep your iPhone's operating system up to date to benefit from battery optimizations.

Reduce Screen Brightness: Lower screen brightness or enable auto-brightness to save battery.

Disable Background App Refresh: Limit apps from refreshing in the background to save power.

Turn Off Push Email: Set your email to fetch data manually or at longer intervals instead of push.

Enable Low Power Mode: Use Low Power Mode when your battery is low to extend battery life.

Minimize Widgets: Limit the use of widgets on your home screen as they can use battery.

By following these comprehensive steps and tips, you can effectively charge your iPhone to 80% (or your desired level) and adopt practices that help preserve your iPhone's battery health for the long term.
