Review on 📱 Superwatch Charge 2 - Wireless Smart Activity and Fitness Tracker with Heart Rate and Sleep Monitoring - Smart Wristband (US Version) by Bridgette Johnson

I bought this charger for Fitbit 2 on April 21, 2021 to replace the charger I bought in 2016. I was able to charge it up and use it until yesterday 17th August. 2021. The battery does not hold a charge and discharges after a few minutes after charging. Tried to do a hard reset with no success. I've been playing with changing the Fitbit app settings but nothing seems to work. It seems to me that this watch is old and the batteries are "dying".? I bought another Fitbit 2 charger but returned it as I couldn't get it to work.
