Soundcore libertey 3 pro left side battery draining fast

both earbuds drain in around 4 hours
the left one is drain after around 3hours with LDAC & ANC on

this is quite disappointing with deceleration of 6-8 hours from Anker

beside that this is outstanding product

One earbud is always draining faster because one is master another is slave.
Declared working time usually is without LDAC and ANC on medium volume. LDAC, ANC and high volume signifantly reduce working time.
