Apple may have apologized for the confusion surrounding its intentional slow down of older iPhones to balance battery life and performance, but that doesn't change the fact that it's happening. If your iPhone is out of warranty and you don't want to have Apple replace it, then perhaps iFixit can help. Starting today, the company has reduced its DIY battery install kits to $29 or less to match Apple's price.
That $29 figure is how much Apple will make you shell out to replace your out-of-warranty iPhone battery through the end of 2018. It's a solid deal, but iFixit points out that you may not want to wait for an appointment at the Genius Bar (or to wait around for the repair to be completed). Additionally, the iPhone 4S, 5, 5S and 5C are excluded from Apple's program.
iFixit's kits are designed such that even beginners can replace their iPhone's batteries, and all the tools are included in the kit. You can peruse the selection here; the iPhone 7 and 7 Plus battery replacements will run you $29, while all older model kits are priced at $24.99.
