My expectation was that I'd be able to use these for an hour or two each day, and just charge them once every 2 weeks or so. The way they presented battery life claims and the way they tested was very misleading.
My thoughts also. Don't know if I'd call it misleading though, I still think there may be a hardware/software issue in at least some of the production units because none of the reviews I read mentioned any significant standby drain (apart from Ars Technica, who quoted about 10% case drain / day with no use). There was some other charging weirdness with mine as well, e.g. after leaving them overnight on opening the case the right bud was at 75% and the left was at 100%. It corrected itself a short while later, presumably because opening the case / waking them up made the case realise it needed to charge the right bud. This makes me think the firmware maybe needs some work.
A friend of mine in particular is worried that he'll charge them, and keep them in his bag, but if he goes to use them several days later they may be dead. I mean, other bluetooth headsets I've been using for years, including ones with small batteries will last for weeks when not in use..
Agree with both these points, which is why I've returned mine. They work well for what they are but the drain in standby means they just don't fit my use case.
