Badger 6 Jun 9:44pm, 6 Jun 2025 17,939 posts	Quote Pin Badger I spent some accumulated John Lewis vouchers on a Fenix 8 (that was cheaper there than anywhere else in any case) and the battery life is extraordinary; it doesn't even seem to make any difference if you're navigating or not. 29% of the charge for a 100k with nav on throughout (and I wasn't fast). @faganj I have a Fenix 5 that nobody has wanted to buy and I would be happy to pass that on to you if the two-watch scenario 0isof interest. Hasn't been used for a couple of years but it was good for 16 hours or so then and I would rather someone was using it than it gathering dust. One interesting thing about the Polar Grit 2 that's just come out is that Polar will replace the battery on it for a flat fee. With that and the Una watch that's just funded on Kickstarter, it would be nice to think that the industry is starting to move to long term serviceability. But it isn't entirely in the interests of companies who only make money when they sell hardware...

It's a great concept, but it's going to have to be better than the equivalent Garmin to stand a chance given all the established infrastructure. Even the likes of Polar & Suunto have never really been able to compete. I do know people who've replaced the battery in their Fenix as the 3rd party batteries with O-rings are readily available online. If mine ever gets to the point battery is an issue I may give it a go. And stop tempting me with the F8. Maybe when the 9 comes out and the prices drop...

I did a long run yesterday and the watch lost 65% battery in 5 hours with maps on for a lot of it. I’m hoping to be round in ~12 hours in July, so I’m thinking it will need a couple of top ups. If that’s not working out, I may come back to you. I’ve got a day hike on Tuesday so I’ll try the battery then.

faganj 13 Jun 10:41pm, 13 Jun 2025 56 posts	Quote Pin faganj Tried charging on the go today and it worked well. I think I’ll need to charge once, or possibly twice in the race. Didn’t take long to go from 48% to 83%, so may just need one longer charge. Thanks for all the advice - it’s been really helpful.
