Fenix 5/5s Plus - 6.57 Beta Release

reginalb whilst I agree that some of the fuss is about boundary cases that probably impact only a small percentage of users there are other issues that impact far more. The battery life issues have impacted large numbers of users (you are obviously lucky on this score) and these seem to have causes that are a mixture of hardware and software (as many people report fixes after replacement watch or battery). GPS for running is poor compared with a number of similar devices - not bad enough to make it unuseable but worse than a number of cheaper Garmin devices - this may be due to the Metal body as the 935 performs better with similar hardware and software. Open water swimming is still not good - better than it was but still poor - I'm surprised that as a triathlete you are not impacted by that.

"Last week, I had a little over 9 hours spent across 3 pool swims, 3 runs, and 4 rides. On the bike, I used a power meter and saw no power spikes in over 4 hours of riding. Running, I spent a bit less than 3 hours, and used bluetooth music for all runs and saw no crashes during the summary voiceovers announcements at the end of each lap. My swims used an HRM-swim, but I haven't heard about any issues with regards to that, but it's worth noting that's another 2+ issue free activity hours. I also used it to navigate to a store walking downtown, and on a couple stroller walks with my daughter."

In the above activities - how much of that did you get on a single charge ?

I don't get stellar battery life, I agree with that being an issue. I get a few days on a charge, but given that I run with music, and I work at a desk, it hasn't been a huge surprise or detriment to me. I don't even wear it as my day to day watch (for that I have a Wear OS watch - as I prefer the more rich notifications and frankly, the display). I am not an ultra runner, if I were, I sure wouldn't be happy with it. I'd probably get a Coros if that was my use case. They are performing downright wizardry with regards to battery life. We will see how that continues as they roll out more and more features for their devices. That said, I don't consider poor battery life to be a "stability" issue, though. I do hope they fix it down the road.

With regards to GPS quality, I don't know that you can really state that the 935 outperforms the Fenix. Firstly, there is always going to be device to device variation - there are likely quite a few 935's that outperform the average 5 plus, there could also be quite a few where it's the other way around. For GPS accuracy I go with 2 things, first there's DCR, who didn't note what you're describing in his review. Then there's my personal experience. I have run the same route near my house with the Fenix 5 Plus now quite a few times, after having run it many times with a 645M and a few aith a 910xt, and the 5 plus outperforms both of those. I am not saying you're wrong, just that I think it's almost impossible to truly know what you're asserting. My 5 Plus occasionally shows me on the wrong side of the road, but it's normally spot-on for reception when I run. It would be awfully hard to test with a large enough number of devices

Actually, my Wear OS watch outperforms all of them on GPS accuracy (though nothing else).
