Last December, Apple admitted to slowing down older iPhones to prevent unexpected shutdowns. iPhone users reacted in somewhat of an outrage. So to please the people, Apple started offering a price cut for out-of-warranty battery replacements. The deadline for discounted battery replacements is December 31 of this year, according to Apple’s website.

With battery replacement prices rising in just a few months, how do you know when it’s time to replace your iPhone battery?

In a perfect world, batteries would be built to last forever and they wouldn’t need to be charged because they’d never run out of juice. Of course, we don’t live in a perfect world, and unfortunately, our batteries are in need of constant recharging. According to Apple, a rechargeable battery is built to “retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions.”

Some things that can tip you off to an aging battery include a longer amount of time for launching apps, lower-than-usual speaker volume, and slow scrolling rates.

Some of these things may also happen if your battery charge is low or if you’re in cold temperatures. In the latter cases, slower iPhone speeds are temporary and should resolve themselves.

How Do You Know If Your Battery Is Still Functioning Properly?

If you’re running iOS 11.3 or later, you will find a handy feature called “Battery Health” under Settings > Battery.

This feature shows your battery’s heath and the maximum capacity of the battery compared to when it was new. In this same section, under “Peak Performance Capability” you will see a quick summary of how your battery is performing.

If your battery is healthy you will see a message stating your battery is operation at peak performance.

If your battery is not healthy and needs to be replaced you will find a message explaining your battery health has degraded, prompting you to replace it in order to restore to full performance.

So if you find your battery in healthy condition you are good to carry on with your life. But, if you see a message saying you need to replace it there are a couple of options.

How Can I Keep My Battery in Good Shape?

Keeping a battery in excellent health isn’t too hard. But there are some pretty common misconceptions from older batteries that no longer apply (such as fully draining your battery before charging). Here are a few tips and ticks that Apple recommends:

  • Store your phone at half power if it will be left unused for an extended period of time.
  • Stay up-to-date with the latest software.
  • Turn on auto-brightness so your phone isn’t working so hard to constantly power the display.
  • Use Wi-Fi. Connecting to a cellular network works the battery harder.
  • Enable Low-Power mode.
  • Remove cases when charging so the battery does not get too hot.
  • Stay up-to-date on your Battery Health in Settings.

Keeping your battery in good condition doesn’t have to be hard. Just stay informed of good battery practices and check your battery health as your phone ages. A healthy battery, is a happy battery.
