It might just be that I'm shifting that much more on the MTB, so maybe not an issue on your Etap? I haven't had the di2 long, but the battery life seems insanely long.
No I haven’t had any issues with AXS battery life on my road bike. I always fully charge before a big ride, but otherwise they usually last for a few weeks between charges. My mountain bike still has mechanical shift so no experience there.
