Xiaomi India — mi band 2 battery issues

Address:

Near Wipro Gate, Electronic City, Bangalore, Karnataka, 560100

I had a battery issue with both the capsules i used before. So i replaced then. On feb 23, 2019, i made another replacement of my capsule regarding she issue i. E., battery. I charged it to 99% and waited till the end of the day, and the charge started falling down. I was completely shocked. I expect them to give some quality products to customers, but the people at the service centers are not at all maintaining standards. Please resolve this issue.
