Thought I would share here after my exploits last weekend as I haven’t seen it talked about.
For those worried about battery life in performance mode, I HIGHLY recommend using the display timeout functionality under custom battery mode.
23 hour effort and I think I finished with about 35-40% battery left which puts it well over the quoted performance spec (performance + timeout + hr belt)
@stromdiddily and also combine this with GPS+QZSS setting.
Also the type of sport can help. I noticed the running profile is much more optimized compared to other sport modes in performance mode.
@surfboomerang yes good point about GPS. I only use the GPS only setting to get the most out of it.
I was using a custom hiking profile, seemed to do ok.
I also think that at such a long duration the need to look at the screen is smaller.
@dimitrios-kanellopoulos 100% agreed. Disabled autolap too which is maybe worth mentioning.
