Nintendo has announced that it will be releasing the Nintendo Switch Lite in September. The Lite version will not support docking and will not have detachable Joy Con controllers.
The Nintendo Switch Lite features a 5.5 inch touch screen with a resolution of 1280 by 720 pixels. This is the same resolution as the original console. However, the original featured a 6.2 inch display.
The console is slightly lighter at 275 grams and will not feature detachable Joy Con controllers. For games that use motion controls additional Joy Con controllers will be required to play. HD Rumble from the Joy Con controllers is also missing.
It will also not contain the docking mode that is found on the original and as such it can not be connected to larger displays.
In terms of battery life the Lite version is said to be able to stay on longer, but the actual battery capacity is lower at 3570mAh versus 4310mAh in the original.
The Nintendo Switch Lite will release on September 20, 2019, and gets a $199 price tag in North America. A European price tag was not announced yet.
