Apple has slashed the price of a battery replacement after news broke that their batteries slow down phones over time.<br />Apple will now offer battery replacement for $29, instead of the usual $79, for older model phones, even if their batteries are out of warranty.<br />According to an internal memo, anyone with an iPhone 6 will be offered a cheap replacement service, with no other strings attached given their age.<br />If your battery still has 80% capacity or more, Apple won't offer the discounted service.<br />And there's another catch, your phone has to pass a diagnostic test at an Apple Store first. <br />
