Try a Garmin. Even the low end ones have way, way more battery life and lots of buttons.
Garmin UI sucks, although I still picked one over Apple Watch due to the price point.
I finally upgraded my ageing 935 to a 955 after 3 or more years and I actually find the 955 to be a joyous experience day to day for everything I need to do and way more. The UI/UX actually feels somewhat well polished now.
Sure, some features and functions are buried, but the amount of functionality packed into it, which is quickly and easily accessible when you get the basic UI structure is unsurpassed IMO. Nothing ever feels more than a few button presses or swipes away, which is honestly a huge achievement given just how much they are packing in now.
The new daily reports and training/workout suggestions are almost always bang on in terms of matching I how feel along with their suggestions for easy days / hard days. The battery life and abundance of buttons just leaves Apple for dust IMO. Add in features like PacePro, easy workout building, training programs, race day planning, integration with everything imaginable - Di2 gears, power meters, etc. Apple will probably never handle a triathlon event - jumping seamlessly from Garmin watch -> Garmin cycle computer -> Garmin watch. I don't think Garmin should feel threatened by Apple here.
Nothing about Apple Watch appeals to me for my use case - running, cycling, swimming, hiking, training status, sleep tracking/recommendations, notifications, music/spotify integration. I've had a couple of Apple Watches over the years and they both got handed on to family members within a month or two. I've wanted to like it, but they are a long way off realistically serving my use-case and this new Ultra version doesn't look to come close either.
I've certainly had issues with Garmin - that atrocious week long service outage a year or two back and also some software updates that made me wonder if any internal QA had been done at all, but overall, Garmin have given me rock solid devices that are best in class IMO. My 935 still looked almost brand new after 3 years of hard usage and still gave me nearly week long battery life (with 5-7hrs running a week).
