So far my battery life has been great on the V1. Can't say about the Q1 though. It is 5:00pm on Saturday here in California and I have had it on since 8:00am this morining and it is still working fine. After I have had it a little longer I will post on it again. Sounds like you had a defective unit(s) if you only got 1/2 hour battery life...or it is a problem with the Q1.
I love this thing! Especially now that I don't have to look at my phone to see who is calling me....it anounces the phone number calling me and asks if I want to "answer or ignore".....if it is a bill collector, I just say "ignore"
