My brother told me to ignore the battery life specs on that new fitness tracker
He said the company's claim of 10 days was based on minimal use, and real tracking would cut it in half. I bought the Garmin Venu 3 anyway last month, and sure enough, with daily GPS workouts, I'm charging it every 4 days. It's a great device, but he was right about the marketing hype. Anyone else find fitness gadget battery claims are way off?
