Constant complaints about battery life: "It doesn't last more than 3 days," "I have to charge it overnight." Yet there are models that last 5 days or more, but the market isn't talking about them. Are our experiences limiting our expectations, or is this perception perpetuated because manufacturers market them as "lasting one night"? In your opinion, what can we actually do with wearable devices for 24/7 use? Is design being sacrificed, or are we losing out on software optimization?
