Battery life is fine, not amazing but fine. I can usually get around a week or so of battery life depending on what I'm using it for. I usually leave it near an outlet anyway so I can plug it in periodically. The portable nature of the device is a nice-to-have for me but I usually just use it in my home. One thing that it lacks is WiFi connectivity - all syncing needs to be done via bluetooth. Which makes sense since it's portable but WiFi would be nice when it's at home. But the device is open and their site gives you ways to make it WiFi compatible if you so desired. I originally found it through a report that showed it as effective as expensive air quality testing gear. It happened to be the only portable one as well that rated that well.
