They were ineligible to be looked at by the Genius Bar, for instance, meaning that getting a battery replacement could mean passing up the chance for any other service work. That was the case even if the problem was with another component and not the battery, meaning that the entire phone would be banned from repairs just for having a third-party battery. We'll tell you what's true. You can form your own view. But a new note seen by Macrumors shows that Apple Stores and Apple's approved service providers will be able to fix those phones.
The reduced-price replacements last until the end of the year, at which point the cost will dramatically increase. For the moment, a new battery costs only £25 – but once the new year arrives, that will rocket up to as much as £65. Old batteries can cause significant problems for their owners as iPhones age. With use, the power begins to drop – something that can lead to phones lasting for much less time, and to Apple having to slow down phones to ensure that they don't crash because they're not getting enough power. It was the revelation that Apple was doing that – throttling performance on older phones, in line with more spectacular rumours that swirled before it was admitted – that led to the cheap repairs in the first place.
