Walking into your local Apple Store and getting a battery replacement for your iPhone is pretty cheap at the moment. Just $29. But when 2018 comes to a close, that temporary pricing — introduced in response to last year’s throttling controversy that affected iPhones with aging batteries — will be going away.

Ahead of that change, as noted by 9to5Mac, Apple has updated its battery page with the new rates that will begin on January 1st. In 2019, out-of-warranty battery swaps will cost:

iPhone XS, XS Max, XR, X: $69

iPhone 8, 8 Plus, 7, 7 Plus, 6S, 6S Plus, 6, 6 Plus, SE: $49

All other eligible models: $79

People with iPhones under warranty or covered by AppleCare+ won’t have to pay anything for battery replacements.

Battery Health, a software feature that Apple implemented after the throttling mess, is now out of beta in iOS 12 and provides a percentage estimate of your battery’s overall condition. When that number drops below 80 percent, it’s usually a good time to change out the battery.
