Apple's iPhone cheap battery replacement programme comes to an end, with just days left to get reduced price

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.
