Battery Drainage on Soundcore Liberty 4

I have only had the Soundcore Liberty 4 for about 10 months & when I use them the Battery drains fast for some reason.
I even reset them but still the Battery doesn’t last no more than around 3 hours which can’t be right.

I am just wondering if there is a problem with the charging case or the headphones themselves?


And no replies… i don’t think my battery is very good either
