I just purchased a Vado 3.0 and after a couple weeks of use I've noticed the battery life is less than I expected. I'm getting around 32 - 34 miles and then needing to recharge. I mostly ride in "sport" mode, but use "eco" at times as well. I occasionally use turbo mode, but it's probably only 10% of my riding. The estimated low end of the range is supposed to be 35 miles and assume that would mean a lot of riding in turbo, which I'm not doing. What are other people getting as far as miles between charges? Could I be having a battery or system probem?
