I recently bought a WF1000-XM4 from the Blue store. Love the audio quality and fits me reasonably well. However observing funny behaviour with the battery. The right bud is loosing battery much faster and at the point of full discharge, difference is about 20%. The overall listening time I get most of the time is 2.5 to 3 hours. Could anyone help me with some guidance on how to fix this and get more listening time. I am on firmware 2.0.1.
