Tried the full reset does not help. Right side now getting worst, the most can last about 1 hour with fully charged. Left side also does not last long the most 1.5 to 2 hrs. Probably time to look for other wireless earbuds.
Swapped the internal battery between Left and Right earbud and now Right side can last about 2 hrs+ and Left side become can last 1 hr. So confirm is the battery holding charge deteriorate, going to order the battery replacement at ebay.
