I only started using GPD products with the Pocket 4, so unfortunately I can't speak to your experience with the Pocket 2. I certainly hope the battery doesn't degrade that fast on their newer models...
The only thing I can say is that they seem to have significantly improved the thermals; IME, the Pocket 4 only gets moderately warm to the touch during full CPU load, and that's even with the quiet fan mode.
