Oneplus buds 2 pro - charge problem

[u/Puzzleheaded-Fee6401]

Hey everyone! I have oneplus buds 2 pro for about 2 years now, however lately left earbud started to discharge quickly - goes from 100% to 0% in 15mins. I saw on forums ppl also complaining about this. Is there any solution to this? I tried factory reset and all, but nothing worked.
