I know it doesn't feel as good as a PSP, I have one which only works plugged in to the wall, it is a big deal to me so I decided to take my save game and finish P3P in my phone with a Razer Kishi, it definitely made it feel better and the save games and fast forward features were a nice addition.

I still feel what you said though... Some devices such as a Retroid Pocket 3+/4 seems like a better option and keeping it in the Android emulation side.
