I am enjoying the new HAs so far but have run into a couple of questions: let me start with I fire them up around 0715each morning and they stay in and working until at least 2100 if not until 2300. I stream pretty much 95% of my phone calls which on any given day can be 30 minutes to and 1.5 hrs and rarely steam music. with that all said I am running the 312 batteries from Varta ( given to me when I got the HAs) the right battery last for 3.5 to 4 days max but on the app it still shows the left one is still at full charge. is it normal for one side to burn quicker then the other and I am changing them both out each time the right one goes dead. thought?
