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.
