Simplicity and battery life are likely related to ones expectations and or desired features. I still use the simplest of Garmin Etrexes and they do all that I require and do it well. All I want are my position, waypoints, a breadcrumb trail, routes, and the ability to download/upload same. No need for topo or ownership maps, aerial photos, barometers, altimeters, touch or color screens, stationary compass, or keeping track of others in my party. Batteries on my units will go for 24 continuous hours, but I've never had continuous needs. Lock in camp, the rig, downed game, crab traps, turn it off, and go about ones business.
Through work, I also use survey grade Trimbles. Many more features than most handhelds, but nothing additional that I'd want for my recreational needs.
I like the KISS principle. Have a couple buddies that have not yet mastered their units, and they're owned them for over a decade.
A cell phone and its accompanying batteries are the last thing I'd count one.
