Review: Defective Battery - Received defective battery. Old battery was charging phone but charge was not lasting. So I purchased this replacement battery for my Xiaomi 9T Pro. Item received with packaging in tact and installation attempted as per instructions. However new battery would not charge. On examination of old and new batteries, new battery is missing a metal part on the end. I am not in US. Return will be costly and is not an option. Now I'm stuck with a defective battery I cannot use 😩

### ⭐⭐⭐⭐ Pretty good back panel and battery replacement kit.
*by J***S on December 17, 2025*

I've been using this for a few months now, and it's a nice little kit. I didn't realize the geniuses at Samsung made the back of my phone out of glass! Brilliant. The battery seems okay. I'm not sure I got any additional charge capacity out of this battery, but my old one was dead and this one is doing the job.
