Hello Rob, here is a short result after the few days of testing.
-The Heat, so my Feeling, seems to be ok. Is not more or less then with or without your mod. BUT: dont Forget, the G4 dont have the same overheat Problems like the G3. Overall the G4 was not very warm. So i think the heat should not be your first Goal. It is very good with the Heat. I played much games and was online, and the heat was Overall ok and not to much. Maybe u can bit improve it.
-The Device feels, and that is for me very very more important, more snappy and fluid with your Mod. I think that should be your first Goal. Cause the G4 has good Hardware but here and there i lags and stucker. that is bit better with your Mod. I think or i would be happy, if you can try to set it more lagfree and snappier. It is better with your Mod, but i think, you can get that bit more on Speed

-Battery Life. Hm..so what i see not improvement and no Shorter live. Seems the same like before......maybe a biiiiiiiiiiit more battery use. Maybe u can watch at that.
Happy if it Comes a new beta soon.
