## Customer Reviews

### ⭐⭐⭐⭐⭐ It works just fine!
*by B***S on June 29, 2025*

Seemed to take a long time to arrive but installation was swift and simple!

### ⭐⭐⭐⭐⭐ Good Battery - Needs Calibration
*by A***R on February 16, 2025*

I installed this battery in my phone a week ago. At first it was draining fast, so I looked up how to calibrate a new battery, went through the process of calibrating it twice and now it is running great in my phone.

### ⭐ I'm putting the old battery back in.
*by T***. on October 24, 2023*

I had high hopes for this battery. Did the 3 cycle total drain and then recharge as recommended. New battery dies in 9 hours. I'm probably going to put the old battery back in and return this one. Waste of time and money.
