Nintendo’s upcoming Switch 2 will introduce a new feature aimed at extending the life of its battery. This function has been available in various devices for some time, including iPhones,

The Nintendo Switch 2 will have an option to cap battery capacity at 90%, similar to a long-standing feature from Pixel phones.

"The Nintendo Switch 2 system stops charging when it reaches about 90% remaining battery" with the new setting turned on. The new setting is literally called 'Stop Charging around 90%,' which Nintendo says will slow down charging speeds at that point. To find the setting you'll need to go System Settings - System - Stop Charging Around 90%.
