It really comes down to is the battery getting used all the time. That’s not the case with DI2 shifters, they only draw when you shift then lay dormant. I’m 7 mos on my DI2 shifters and the battery level display still shows full. Unlike an Garmin speed sensor that is constantly transmitting during a ride, I find they don’t last that long.
