I switched a month ago because of this exact reason. My Apple watch would last 12-14 hours tops. It shut down during one of my runs and that was it. Bought the Garmin Forerunner 570 and haven’t looked back.
Forerunner 55 for the absolute basics. Forerunner 165 is the cheapest with a AMOLED screen. Forerunner 255, 265, 955 and 965 are just discontinued. In my opinion 955 is the most value for money as it includes mapping. 965 is the same watch as the 955, but with an AMOLED screen. If you don’t need mapping, then go for the 265. It is the same as the 965, but without maps. So if you can find a 955 that would be your best bet in my opinion. Forerunner 570 and 970 introduce unnecessary features, such as microphone & speaker, sapphire glass, shiny metal bezels all of which add nothing to running but do increase the price.
Venu 4 all the way. I was between the 570 and the Venu 4, bought the latter and I'm super happy.
I have a forerunner 570 and it’s great, use it for swimming, running, skiing, etc.
Not familiar with other model except forerunner. I would go for 570 but if the budget fits, I would go for 970. Flashlight, Sapphire glass, titanium bezel & speaker among other upgrades. Download the optimity app to get discount by doing a couple of clicks everyday. Or ask around here. I like the forerunner bec. it got dedicated buttons for runners. Very handy. The UI hasn't change that much since my first forerunner. A 210. The 970 has specific features like morning and evening report. Built in maps. It is first and foremost a running watch and a smart watch second.
What others have said. Smart watch vs running watch is the real choice. In theory, Apple watches have more than enough juice to run a marathon. In practice, sometimes they drain battery faster for whatever reason. I traded in my s10 for a Garmin 570 around 2 months ago as my runs got longer and I had a 13 mile training run drain my battery from 90% -> 10%. Can’t say Garmin is all sunshine and roses (much of their app UX is garbage, including just not explaining what does/doesn’t trigger certain stats to update) - but I can definitely say I don’t worry about battery life anymore.
