Band charging issue

Ordered two bands on early release and one band works fine the other band when first put on charger showed 96%. During setup and on the charger for hours it never moved from 96%. So tried the charger that came with the other band and after hours on charger it was still 96%. Now three days later using the band it is still at 96% but the other band that appears to be fine and charged to 100% now at 86%. Any ideas or suggestions for a fix? I sure don’t want to deal with a return or support as messed up as thing currently are at Wyze.
