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.

Frequently Asked Questions

Each replacement battery is designed for specific iPhone models. Check the “Compatibility” info box on this product page for details or use our compatibility checking tool to find out whether your model is compatible. If you’re unsure which model you have, you can verify under Settings → General → About or use the model identification information provided in the compatibility checking tool.

iPhone 6s Battery | New / Fix Kit

It did solve my problem although it was obvious the battery was the problem. It is a stressful repair with tiny tiny screws. The tabs on the display panel that the two screws on either side of charging port attach to, can be bent during removal/ reinstall. The screw/screws may not start back. Make sure the threaded tabs are square with the display panel AND….there is no glue or debris in the back cover ( especially on top of the back cover)

iPhone 6s Battery | New / Fix Kit

When Apple informed me that they, "no longer manufacture the iPhone 6s battery," I was determined to find another source before discarding the otherwise perfectly operating phone. Not only does iFixit offer the necessary battery with a full kit of the needed tools, their step-by-step detailed guide took all of the guesswork out of replacing the battery. I successfully replaced the my iPhone 6s battery on the first attempt. The iFixit battery is identical to the original Apple one except the for the labeling. (I suspect the iFixit battery and the original Apple battery are made in the same facility.) The iFixit replacement battery exceeded 6 hours of constant video and audio after the first full 100% charge. My iPhone 6s runs like it is brand new now, with the iFixit battery lasting for days on standby without charging. While not photographed in the kit contents, there are two replacement bottom screws included with this kit, too. (These are mentioned in the kit contents.) I ended up not needing these screws, but appreciated them being included nonetheless. I also very much appreciated and valued the fellow customer comment in the guide steps. I opted not to replace my faceplate seal and that saved several steps by not requiring the faceplate to be fully detatched. Be sure to read all of these valuable comments before you begin since they offer additional tips to accompany the iFixit guide.
