Nikoyay my music player used about 30% and I used that was over 2 hours.
Under battery change apps usage to system usage. There are line items for: audio, Bluetooth, WiFi, cell antenna, etc.
There are other factors that could be at play. Maybe your lineageos phone has a bigger battery, more efficient with electricity, you changed residence or work locations during the new phone switch and you used to get 90% signal strength on WiFi, cell, BT and now one or more is 20% signal strength taking more power.
