Review: GameSir F4 Falcon Mobile Gaming Controller for iPhone

I've reviewed several game controllers from GameSir, but the latest one is a sharp departure from previous models. The company sent me the F4 Falcon Mobile Gaming Controller ($35.99). While most of GameSir's other iPhone game controllers are large and enclose or prop-up the entire iPhone, the Falcon is quite compact and folds into itself to be smaller than a computer mouse. The wings expand, like a falcon, and it can clamp on to an iPhone.

Unlike other gaming controllers, the F4 does not use Bluetooth to control the action. There are two "arms" that hang over the top of the phone barely covering a small part of the screen, The idea is you can play games that allow movable virtual buttons. GameSir maintains a list of compatible games. You drag the virtual buttons to the top of the screen and then get a good view of the whole game, as your hands and fingers don't block the action. Instead there are two action buttons on each side of the Falcon's wings, one serving as a turbo button.

The F4 has soft cushiony padding so it won't scratch your phone, which is wise because it works best with no case or a very thin case,. The unit does require power, to act as a capacitive button, and has a 40-hour battery life and charges via USB-C.


  • Game controller that touches the screen for you
  • Does not use Bluetooth or Lightning port
  • Soft padding prevents scraches
  • Long-lasting battery


  • Requires games that allow movable virtual buttons
  • Best with no case or a very thin case

Final Verdict

The F4 Falcon Mobile Gaming Controller from GameSir is a compact add-on that can improve your game.
