r/GarminEdge

I was initially worried about the battery life from initial reviews but decided to pull the trigger for the better screen.

Yesterday I just completed my first century. 100miles in 6h30m with 4 stops. I run my 850 pretty much stock out of the box with connected heart and power sensors with screen brightness at auto. At the end of the ride I was left with 48% battery life.

I genuinely cannot think of a scenario where I would need more battery life than this. And if I ever needed to run an 10h ride or something obscene, I would just carry a light weight battery pack.

For 99% of use cases the 850 battery is perfect. Don’t bother with the negative reviews, the screen resolution is worth it!

Edit: adjusted for elapsed time instead of moving time

Hi - I signed up for my first 70.3 and am starting to upgrade my bike.

I have a garmin watch and HRM, so wanted to stay in that brand for compatibility. I am upgrading my pedals to power meters, but am wondering which bike computer to get (Garmin Edge Explore 2 or Edge 850/550). Any thoughts on the differences or which will better fit my needs? Even if I don't do triathlons after this one, I will still continue to cycle.

I want ERG to hold the target as measured by my 4iiii, so indoor and outdoor power match.

**Setup:** KICKR CORE (gen 1), Edge 840 runs the workouts in ERG, 4iiii left-only crank PM. In the Wahoo app "Control w/ ANT+ power meter" is on with the correct ANT+ ID, ERG smoothing off.

**What happened:**

- 4iiii paired to the Edge too: the KICKR ignores it. Fixed 200 W for 10 min → 4iiii averages 181 W, no convergence.

- 4iiii removed from the Edge: KICKR and 4iiii numbers line up, but ERG no longer holds the target (under 100 W after 1 min at a 200 W target). The Wahoo app might still have been connected – retesting this week.

**Questions:**

1. Anyone got this working with a Garmin Edge? What exactly is paired to the Edge?
2. How long does the matching take to settle, and does it reset after you stop pedaling?
3. But the PowerMatch feature in the Wahoo app should actually work, right? So that the watts measured by the power meter can be used as the basis for the erg mode.
4. If you gave up: what did you switch to (Zwift/TrainerRoad/TP Virtual power match, Level mode, …)?

Thanks!
