Nintendo Switch's battery life will range from 2.5 to 6.5 hours, Nintendo has said. That's a wide range of estimates - but it'll depend on what game you're playing.

Nintendo is confirming new details in rapid-fire succession - including Eurogamer's exclusive report from last year that the Switch will have a capacitive touchscreen.

Up to eight controllers can be connected to the system, and each Joy-con controller will have gyro controls. There's also a Capture button to nab a screenshot. After launch, you'll be able to capture video as well.

In fact, there's more within each Joy-con controller than expected, including "HD rumble" to provide chunky feedback. Nintendo gave the example of it feeling like rattling ice cubes in a glass.

Most bizarre of all, a rudimentary kind of image sensor will be included to detect simple hand gestures - such as a thumbs up, or rock, paper, scissors.

Here's how Nintendo Switch will work, according to Nintendo Watch on YouTube
