The Charge 4 has built-in GPS, while the previous ones didn’t. I hear it does use battery capacity much faster as you might expect, but it would be handy if you didn’t want to bring your phone.
I actually just let the Charge 3 automatically track my exercise and it gets it right most of the time, though then all you have is HR and not GPS route data.
As you say, it’s hard to read the display in daylight, but it’s under sunsleeves or long sleeves when I’m cycling so I’m not really looking for real time display. I mainly track cycling by perceived effort or pace and use the HR plot as a confirmation afterwards. When I’m running, I can usually see the display and it’s quicker and easier to stop to check it if I want to.
