iOS 11.3 is now available, and it's packed with new features designed to improve and streamline Apple's mobile OS.

One of the most anticipated features of iOS 11.3 is the option to disable device throttling to save the battery. The controversial move to automatically throttle older devices to preserve battery health was met with major pushback from iPhone users, leading Apple to discount battery replacements and add the new feature to iOS 11.3.

How to install the latest version of iOS on your Apple device

In order to see the option to disable device throttling you'll need to be on iOS 11.3 or later. Here's how to make sure it's installed on your iOS device.

  1. Open the Settings app.
  2. Swipe down until you see General. Tap on that.
  3. Under General, tap on Software Update.
  4. The Software Update screen will either tell you that you have the latest version installed or prompt you to update to the latest version of iOS. If you're on a version older than 11.2 you may have to perform more than one update to bring your device current.

How to disable device throttling

Not only does iOS 11.3 give users the option to disable the CPU throttling that caused so much controversy, it also adds a lot of battery health information. Apple added features to display the health of the battery and inform the device owner if the battery needs service. That information can be found in the Settings app under the Battery tab.

To find out if your device is being throttled, go to the Battery tab and look for the button labeled Battery Health--tap on that.

On the screen that appears look for the area that says Peak Performance Capability. Under that you'll see a bit of text saying that your battery is currently supporting normal peak performance, or that performance management has been applied. If it says the latter, throttling has been enabled on your device.

Along with the message saying that performance management has been applied you should see the option to toggle it off, and disabling it will disable device throttling. If you don't see the toggle your battery is in good shape and you don't have anything to worry about.
