Fenix 6 Pro battery life as a Bike Computer

Specs say up to 36 hours in GPS mode. This will be reduced somewhat if you are displaying maps for navigation, using backlight extensively and have a permanent phone connection for live tracking or music control.

Specs do drop to up to 10 hours with GPS and music, so choose your usage wisely. 

Oh, and if you don't have a bike mount and want a cheap solution then pipe lagging can work well. 

I have used during 8 howers and battery remaining. That means more than 8 hs

Thanks for the reply! i wont be using music, and the only external connection would be HR so from the sounds of this, I should get well over 12 hours of usage.

I don't use music, but I use Blue Tooth connection whith the phone, cadence & speed sensors.

It sounds like you can go a head 12 hours

100 mile it's not 12 hours, max. 8-9

One issue with the Varia is that each car triggers an alert on the watch/head unit. Depending on the backlight settings, this can result on a lot of backlight uptime. I used to find the Varia significantly shortened watch/head unit run times on long rides, with backlight that you don't really notice in daylight.  Since setting my backlight settings more conservatively with a faster timeout, I have found my watch and head unit battery life has increased considerably.

I'd love for this to be sub 9! but.. planning for a near 12 tho
