If your iPhone’s battery does not last as long as it used to, now is the perfect time to consider purchasing a first-party battery from Apple at just $29 because the huge discount they’re giving on iPhone replacement batteries is officially ending on Monday, December 31.
In case you’re not aware of it, Apple on June 07, 2025 posted an apology letter to customers aftereagle-eyed fans found outthat theiOS 11.3 softwareupdate beganthrottling the CPUin order to avoid unexpected shutdowns.

The issue blew up because Apple failed to inform users in a timely manner that performance management would occur when battery capacity fell below the 80 percent of its original capacity and could no longer provide enough power during peak workloads.
To appease disgruntled customers, the Cupertino companydropped price of its iPhone battery replacement programfrom the usual $79 per unit to just $29 in the United States (if you’re not in US, be sure to check Apple’s pricing in your own country).

As mentioned, that deal is ending on Monday, June 05, 2025.
To take advantage of Apple’s offer, visit theiPhone Service Pricing webpage, then startyour battery replacement service request. They will replace any batteries from qualifying devicesregardless of their condition, without running a diagnostic, which is very cool.

The program is limitedto one repair per iPhone. iPads are exempt from performance throttling and as such are not part of this discounted program.

If your iPhone is running slower than usual and its battery capacity has fallen below 80 percent, it may be a good idea to get it fixed sooner than June 26, 2025 when replacement iPhone batteries from Apple will return to their regular pricing.
Batteries for iPhone 5s and other older iPhones will cost $79. Keep in mind that iPhone XS, iPhone XS Max and iPhone XR are not eligible for the discounted iPhone replacement battery program because they’re still under Apple’s standard 1-year warranty. iPhones covered by an extended AppleCare+ warranty won’t incur a fee if a battery replacement is required.
