The Nintendo Switch Lite is a revision of the Switch designed for handheld play released worldwide on September 20, 2019, with an MSRP of US$199.99. First announced in July 2019, the Switch Lite integrates the controller hardware into the main unit, and uses a smaller screen measuring 5.5 inches (14 cm) diagonally. Additionally, a regular directional pad replaces the four directional buttons on the integrated left Joy-Con. While using a smaller battery than the original Switch, the Switch Lite uses a more power-efficient chipset, the 16-nanometer Tegra X1+, to extend the estimated use time from 2.5 to 6.5 hours to 3–7 hours on a single battery charge.
According to The Wall Street Journal, Nintendo's goal with the Switch Lite was to produce a sub US$200 unit, aimed at casual gamers, to compete with gaming services that do not require a dedicated device. To achieve this, Nintendo negotiated on reduced prices from its component suppliers. Further, the Journal stated that Nintendo had gained Murata Manufacturing as a battery supplier in addition to TDK, to lower costs by causing competition between the two companies. The Switch Lite is physically larger than previous Nintendo handhelds: its display is 0.62 inches (1.6 cm) larger and the unit measures 1.9 inches (4.8 cm) longer when compared to a New Nintendo 3DS XL, which itself was the large-sized model in the Nintendo 3DS line.
The Switch Lite normally only supports games that can be played in handheld mode, retaining features like the Switch's gyroscopic sensors, Bluetooth, Wi-Fi, and NFC compatibility. Some tabletop games that require the HD Rumble or IR camera features, such as 1-2-Switch, require players to use separate Joy-Con controllers with the Switch Lite. The system does not support any docking or connectivity to a television and is thus incompatible with games that require television mode. Players who attempt to purchase games that require television or tabletop mode via the eShop on the Switch Lite will be notified of the incompatibility. Though not included with the system, the Switch Lite does support external controllers otherwise compatible with standard Switch models, such as standalone Joy-Con controllers, though they cannot be docked to the system. Some controllers, such as GameCube controllers, work with the system, but require extra adapters, as the normal GameCube to Switch adapter uses the USB ports on the full-size Switch's dock.
