Review: This is “compatible” at best. Never gets to 100% and never gets to 1% - This battery has a very poor quality. First of all is very light and smaller than the Original Xiaomi battery, also despite my original battery having over 380 cycles, the charge holds for longer with the used battery. This never gets to 100% and it discharges pretty quickly, also the indicator seems to be off since sometimes I get stuck with 1% for hours!!! Or sometimes it just shuts off around 20%. Of course I’ve calibrated this battery and it’s honestly a piece of trash. Don’t even waste your energy swapping it ## Features - This battery is specially designed for MI 9T Red mi K20 M1903F10G M1903F10I, it can replace your old battery, Tech skills may apply when replacing the battery. - The battery comes with high quality repairing tools and 3M adhesive tapes, no instructions for installation, a professional technician is recommended if you don’t know how to replace it by yourself. - If the product you received is broken, crashed or dented, please do not install it in your phone, tablet or your laptop, contact us firstly and we will help you to resolve the problem immediately. - Installation videos could be found on the internet like YouTube. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08S3QHTM9 | | Batteries | 1 Lithium Ion batteries required.
