Very low battery on my Razer Blackshark V2 Pro

For more than 2 years than I’ve been using my headset, I used to charge it only once in 3 days, and the charge would last very long, but now since a few weeks the battery has been very lowered.
First, when I check Synapse and i plug off the charging cable, it instantly goes to 80% battery, and I feel like I can only use my headset in wireless for about a few hours (2 or 3 probably, I need to check)
I don’t know if its related but, in 2025, I haven’t been using it much, so it just sit on my desk for a long while, unused.
Is there any chance it affected the battery ?
