Re battery life:
- Out on the road V2 seems to sip juice frugally;
- But get it under cover / in a building where it’s struggling for a GPS signal and it sups like a starved vampire from the necks of virgins
I’d normally start up the Bolt a “short while” before my ride commenced; then gather/load water bottles, gather ride snacks, don shoes / gloves / helmet / jacket etc, zero PM, start Varia, check HRM, load Route - generally Olympic levels of faffing 
. But, I’ve noticed that with the bike inside a building or garage, the V2 is slurping power at maybe 1% a minute, which is a little unnerving…
Unnerving enough to: (1) rethink my faffy start routine; and (2) hope I don’t find myself on a ride where for some reason the V2 struggles for signal for a good chunk of time (eg. parked under cover at a caff stop?), because juice levels could plummet and risk running dry later in the ride.
Never really noticed this issue with the V1.
