15000mAh Replacement Battery Used for iPhone X, High-Capacity 0 Cycle Li-Polymer Battery - Compatible with Models A1865 A1901 A1902 Includes Full Repair Kit

This replacement battery for the iPhone X sounded promising with its high capacity, but it didn’t live up to expectations. While it does work, the performance isn’t as strong or consistent as advertised—the battery drains faster than expected for something rated at 15000mAh. Installation was also trickier than described, even with the included kit, and it required more effort than I anticipated. It’s usable, but overall the quality feels average, and I’m not confident in its long-term durability.

The battery works great as intended. You can feel the much larger capacity than the original manufacturer battery. It’s a great upgrade, definitely worth popping open your phone if your phone dies quickly.

Battery showed 100 percent health but continued to die rapidly and also showed that it was at 80% and eventually it randomly died and it continued to do so till it did not want to turn back on it kept tiring on and off by it self on the charger. After taking it back out I placed my old battery in and that’s when I realized it’s not my phone it’s the batter.
