How to Reset Battery Health on iPhone

Your iPhone’s battery health is an important aspect of its overall performance. Over time, the battery capacity may decrease, and you might experience shorter battery life.

However, there is a way to reset the battery health on your iPhone, which can help improve its performance and extend the battery life. In this tutorial, we will guide you through the steps to reset the battery health on your iPhone.

Step 1: Check Battery Health

Before resetting the battery health, it’s important to check its current condition. To do this:

  • Step 1: Open the “Settings” app on your iPhone.
  • Step 2: Scroll down and tap on “Battery”.
  • Step 3: Select “Battery Health”.

This page will display information about your battery’s maximum capacity and peak performance capability. If the maximum capacity is significantly lower than when you first bought the device, it may be time to reset the battery health.

Step 2: Perform a Full Charge Cycle

A full charge cycle involves completely draining your iPhone’s battery and then charging it back to 100%. This process helps recalibrate the battery indicator and can improve its accuracy.

  • Step 1: Use your iPhone until the battery drains completely and it turns off automatically.
  • Step 2: Connect your iPhone to a charger and let it charge uninterrupted until it reaches 100%.

This step may take some time depending on your device model and charger. It’s advisable to leave your iPhone connected to the charger for at least a few hours after it reaches 100% to complete the charge cycle.

Step 3: Force Restart Your iPhone

A force restart can help resolve minor software glitches and improve battery performance. To force restart your iPhone:

  • Step 1: Press and hold the power button (located on the right side or top of your device) and either volume up or volume down button simultaneously.
  • Step 2: Keep holding both buttons until you see the Apple logo on the screen.

Your iPhone will restart, and this process may take a few seconds. After restarting, check if there are any noticeable improvements in battery life.

Step 4: Update to the Latest iOS Version

Apple regularly releases software updates that include bug fixes, performance improvements, and optimizations. Updating your iPhone to the latest iOS version can potentially address battery-related issues.

  • Step 1: Open the “Settings” app on your iPhone.
  • Step 2: Scroll down and tap on “General”.
  • Step 3: Select “Software Update”.

If an update is available, tap “Download and Install” to begin the update process. Make sure your device is connected to a stable Wi-Fi network and has sufficient battery life or is plugged in during the update.
