Sony WF-1000XM4 Charging Case Battery Replacement
@haasjona thanks you for the info! I'm in the process of replacing the batteries in the buds. Im thinking I might as well replace the battery in the case as well.
The linked battery is 500mAh, but the battery in my case is 520mAh. Will this make much of a difference? Or should I find a 520mAh one?
