Quality Parts For Quality Repairs

iFixit's iPhone replacement parts are meticulously tested and backed by our Quality Guarantee. We've spent over a decade scrutinizing component manufacturers and aftermarket suppliers so that you can trust the parts you receive.

Good Battery = Good Experience

Even if you don’t mind plugging in every day (or more), a worn-out battery can cause problems like overheating, performance slowdowns, and unexpected shutdowns. Swapping in a fresh battery restores reliable power so you can focus on what matters.

Right For The Environment & Your Wallet

It’s not just more sustainable—it’s cheaper, too. Replacing your iPhone battery with an iFixit Fix Kit can save you anywhere from $34 to $49 compared to Apple’s out-of-warranty service—depending on your model.

iPhone 12 Pro Max Battery | New / Fix Kit

Kit has everything I needed to replace the battery. Instructions were very good. I also read the comments left on the different steps. They were helpful also. Took me about an hour and half. I went slow, so not to break anything. I would recommend to anyone. I thought I was going to have to buy a new phone before I found this kit. Not any more. The kit is a very good value. Thank you.
