An updated version of the Nintendo Switch under model number "HAC-001(-01)" was announced on July 17, 2019, and was released in Japan and North America in mid-August 2019, and in the United Kingdom in September 2019. This revision uses the Tegra X1+ SoC, a more efficient chipset compared to the Tegra X1 used in the original model. Thus, the time-on-battery was effectively extended to 4.5–9 hours, depending on the game being played. No other system component was updated in this revision.
