Video: How to check if your iPhone battery needs to be replaced
Late last year it came to light that Apple has included code in the iOS operating system that throttles the performance of iPhones if the battery is showing signs of wear. The good news is that Apple will carry out a battery swap for $29, but how do you know if it will help?
According to Apple, the iPhone’s battery is designed to retain up to 80 percent of its original capacity at 500 complete charge cycles, so if the full charge capacity is less than 80 percent of the design capacity, or the recharge cycles exceed 500, then your battery is considered worn.
In my example, the full charge capacity is well above 80 percent of the design capacity, but I have three hundred additional recharge cycles, which means the battery is getting on a bit. However, the only benefit I’d get from a battery replacement right now is increased lifespan since the device isn’t being throttled.
Another way — albeit more cumbersome — is to install the latest iOS 11.3 public beta. First off, if you want access to the public beta, you need to sign up. You can do that here. Before you go any further, you might want to take a look at my list of precautions and caveats related to running beta software on your iPhone. While you can easily roll back from running the beta, it’s possible for the beta to cause havoc in the meantime.
After you’ve installed iOS 11.3 public beta, head over to Settings > Battery. There you will see a new option labeled Battery Health (Beta). Click on this to find out more about your battery.
Note that this feature applies only to the iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7, and iPhone 7 Plus.
If your device is operating normally, this is what you’ll see:

If your battery is worn, you’ll see this:

If the battery is worn you will be offered the ability to disable performance throttling, as well as get information on how to get the battery replaced. Note that if the iPhone experiences an unexpected shutdown as a result of battery performance, power management will be turned back on.
