XYIRMCYF 19900mAh Super Capacity Battery Compatible with iPhone 12 Pro Max, 0 Cycle Li-Polymer Replacement Battery for iPhone 12 Pro Max, with Professional Repair Tool Kit

The only problem with this battery is that it doesn't meet my expectations for capacity. I initially thought it would have double the mAh of the original Samsung Galaxy battery, but it turned out to be less. After a few uses, the original battery in my phone, which I've used for over six years, has degraded from lasting about six hours to around three or four hours. I hoped the new 10,000 mAh battery would last approximately eight hours based on simple calculations, but that’s not the case. Charging the battery to around 85% provides the best protection, but even when fully charged to 100%, it only lasts about six to seven hours instead of the expected twelve hours. This shorter lifespan is disappointing, but understandable given that it’s a cheaper battery. The charging speed is satisfactory. However, it's important to avoid letting the battery drain to zero or overcharging it, as these practices can cause micro-damages that reduce the battery's duration, lifespan, and capacity.

Charges great, Instructions were easy to follow. Works well seems durable, Battery quality is great as it has been used for the last 6 months or so with no isses. Would buy again no problem.

Not recommended. Immediately after I installed my phone stated battery not verified. Then it started freezing and restarting in cycles of about 3 minutes or so. Apparently I searched internet and found similar scenarios on reddit saying it shoots surge current on charging port. This battery gave me a huge loss I regret purchasing because the old battery was still good at 85%. As I type, I have a new phone the iphond is dead

well packaged with all tools yo install

I’m on Day 1 after installing. The parts and provided tool kit seem to be of decent quality and work well. The battery seems to work as it should so far. However, the phone does give a non-genuine Apple battery error after installing. The calibration function didn’t appear to work either. It’s not a big deal. It still works fine, but some might find the error frustrating, so I felt compelled to mention it. At the price, it’s a good value to extend your older phone’s useful life.

Came in quicker than expected, well packaged and a good fit for my hotspot

It gives message in settings that the battery is not recognized. It is a bang for your buck, but the tools provided are absolute garbage. If you want to install it right use your own tools. Also, the stickers provided for the battery are not the same as the OEM. Lastly, the border seal is slightly larger than the phone and does not align. Let’s see how long the battery last and it’s super Chinese.

I got this to refresh my old iPhone SE that I really don't want to replace - and the only issue with it was battery life. This is a GREAT solution! I've been using it for about a month at this point. It charges very quickly and has better capacity than the original battery. The installation was not super simple, but my engineer husband took care of it. The hardest parts were removing the Apple battery and trying to re-install a little seal to try to keep the phone waterproof (that comes in the kit). Instructions are sparse...look up how to do this on YouTube and watch before you try the installation. Overall, I am extremely pleased with this new battery.
