Razer blackshark v2 pro 2020 battery and charging issues

Hi, I LOVE this headset, but lately the battery life has jumped off a bridge, i always charged them overnight and they never gave out on me even when i was grinding for 24hs or more. Now they can only function for give or take 10 hours and the synapse data on battery level goes crazy, ive already had the battery itself swapped out but it didnt help.
