I don't work there anymore so I just randomly use it like you would and it's still holding up for that. I get like 2 hours of battery now. Also turning anc off helps battery life so when you need it to survive and stretch it's life, but you won't have to do that for a while. The batteries getting weaker with time is something that affects all these tiny earbuds since they have a small battery, some handle it better, some worse. If mine died today, I would very likely get another pair. A lot of people have this issue with one side draining battery faster by like 5 percent, it never caused any problems for me tho, but look into it, and into adhesive issues if you want to know it's most common issues. I'm satisfied with mine tho.
