Apple has slashed its iPhone battery replacement service fee to $29 from $79 after admitting to slowing down older models with worn-out batteries, but those looking to take advantage of the offer should know that the discounted pricing is limited to one repair per device.

According to new fine print on Apple’s iPhone Service Pricing webpage, which was discovered yesterday by MacRumros, the advertised $29 battery service fee “may be limited to one repair per iPhone” when an eligible device passes diagnostic test.

As the publication notes, this means that after you’ve had your iPhone’s battery replaced once this year at $29, the phone must explicitly fail the diagnostic test to qualify for any additional battery replacements for $29. “If the test passes, a customer can still choose to have the battery replaced, but Apple’s standard $79 fee applies,” reads the article.

As a quick refresher, iPhone batteries are designed to retain up to 80 percent of their original capacity at 500 complete charge cycles.

Devices that are eligible for the discounted battery service pricing include iPhone SE, iPhone 6s, iPhone 6s Plus, iPhone 7 and iPhone 7 Plus models.

Apple previously said that the $29 fee is valid through December 31, 2018.

As we previously reported, all Apple customers that request a battery replacement will get one, regardless of of the results of the battery diagnosis run on the device.

Nearly 30 class action lawsuits have been filed so far over the iPhone throttling debacle.

    And you should mention that they don’t give that discount in all countries!

    I took my iPhone 6s Plus in last week Wednesday to the Apple Store with a reservation. After many questions and looking at the phone, they did the diagnostic test which supposedly resulted in a “still good” battery. The random shutdowns, specially in the cold, and all the lagginess says otherwise. They told me they will do the $29 battery service but I will have to wait 7-10 business days for them to receive the battery. What a waste of time. I’m still waiting for their call to let me know when they have the battery.

      The cold shut down has been going on for a long time ever since my i4. Brand new i5 and i6. New or old! Now matter what iOS! You have to keep it warm

    • Lithium-Ion batteries do not perform well in cold. In fact running a new battery in very cold conditions can yield as bad of performance as someone with a battery that is years old. I don’t know what your situation is but I’d try and keep your phone warmer if at all possible.

      But do not keep it too hot, because then it will shut off too.

      Cold or not, my phone still shuts down and restarts in room temperature from time to time.

    Is this limitation something new? Does this have anything to do with the incident in the Zürich store today?

    yes I went to my appt at the Genius Bar, they did the whole thing,
    and then she told me they didn’t have any batteries in stock, now why that couldn’t have been stated at the onset .
    however I am getting a new battery for $30 for my nearly 4 y/o phone shrugs
