We show you how to check if your iPhone needs a new battery

If you feel like your iPhone is running a little slower than it used to, or if you notice that the battery life doesn’t seem to be as good as when you bought it, it may be time to replace it.

This is because the batteries in the devices we use slowly get worse as they age. Apple’s iPhone software tries to make up for this: If your phone turns off unexpectedly, it can slow down your phone to preserve battery life and try to avoid unexpected shutdowns, which is an annoying surprise for most people.

But a better solution is to replace the battery completely.

There’s a way to quickly check to see if your phone is slowing down, which means you should probably send it (or take it to an Apple store if there’s one around you open) to get a new battery.

This is what you should do.

• Open Settings on your iPhone.
• Choose battery.
• Tap “Battery Status”

You will now see the “Maximum Capacity”. The lower it is, the shorter the battery life will be. Apple’s battery site says that “a normal battery is designed to hold up to 80% of its original capacity” and that a one-year warranty includes service if your battery is defective.

But a year-old iPhone should generally be fine.

My iPhone 11 Pro Max purchased in September (not a year ago) has a maximum capacity of 96% right now. However, you may want a replacement if you see that its maximum performance capacity is around 80% or less.

Then check the next area on the page. If it says “Maximum Performance Capability”, that means your iPhone is running at full speed and is probably fine.

But if it says “Performance Management Applied”, that means your iPhone experienced at least an unexpected shutdown due to battery life, and Apple software is now speeding up performance to prevent that from happening again.

You can disable this so that your iPhone runs at full speed tapping “disable” at the end of the warning message, but the best option is to replace the battery.

You may also want to replace the battery by saying “Performance Management Disabled”, “Unknown Battery Status”, or “Degraded Battery Status”.

You can replace your battery by making an appointment at an Apple store or shipping it to Apple, just visit the Apple website to see what works best for you.

The good news is that a battery costs much less than a new phone. If you have AppleCare +, which you buy when your phone is new, you can replace the battery free of charge.

Otherwise, it costs $ 69 to replace the battery of an iPhone 11, iPhone 11 Pro / iPhone 11 Pro Max, and iPhone X / XS. Or it’s $ 49 for the iPhone SE, iPhone SE 2, iPhone 6 / 6s / 7/8 and their larger “Plus” counterparts.
