I would like a flagship spec (especially RAM, give me all the RAM possible) phone with a small screen and a massive battery life; sacrificing other components to put a big battery. One small camera is enough for me, I don’t need 3 cameras on the back of my phone. I would also get a small, single speaker to save internal space, and remove the haptic system entirely in exchange for a larger battery.
I wouldn’t sacrifice the headphone jack though, I hate using dongles.
