For all those Nintendo fans who play well and happy times for more than four hours at a time, the GamePad-high-capacity battery is a must. Due to this, the duration of the gamepad extended by an average of three to four hours. Of course, this depends on the settings of the gamepad's regarding power saving mode, brightness and rumble effect from. I personally use four brightness level, have the rumble effect is activated and the power saving mode disabled. Without GamePad-high-capacity battery went to about four hours proverbial light on the gamepad out, with there are now at least eight hours!
