Mine is a newer 2X Solar. The solar definitely helps (although obviously only when the sun is out, winter training might not be similar). I have just over 40% remaining after a few weeks and like 3.5 hours of gps tracking time. Im definitely sold on the solar part. My only Apple Watch comparisons are the first few generations but HR seems similar to those (good enough to be useful but probably not as good as a real chest strap).
Just had a look at this, interesting, although it is bolstering its battery life with solar power.
Do you have real world experience with it? Does it last as long as it claims? I have to charge mine every 2 - 3 days as it is right now.
