I hope it does... I don't need best in class, but I do need the battery drain of both data recording and gps off of my phone. So a good first edition device should be fine. Main concern is if the elemnt will require the wahoo fitness app to get call/text details, since my experience is that app has poor battery efficiency. And it's not that good in general - I'll probably still export/import files to cyclemeter for safe keeping.
