## Customer Reviews

### ⭐⭐⭐⭐⭐ Comes with tools needed for replacement
*by J***P on August 7, 2025*

Apple has now moved the iPhone XS Max into Vintage status, meaning they will no longer product replacement hardware for it. That includes new batteries. If your iPhone XS Max is in need of a battery replacement and you're inclined to DIY, this kit is perfect. Replacement battery and tools and materials needed (including new moisture seal for the display) are included in this kit.
