What is the “90%” setting on Switch 2?

The “90%” setting refers to a new battery-preservation option on the Switch 2. When enabled, the console will stop—or significantly slow down—charging when the battery reaches around 90% of its capacity rather than continuing to 100%.
Nintendo says this helps reduce long-term battery deterioration.
To find it: go to System Settings → System and look for “Stop Charging Around 90%”.
Summary: It’s a convenience & longevity feature, not a performance mode.

How do I get to System Settings on Switch 2?

Here’s how to access the system settings:

1. From the HOME Menu on the Switch 2, select the System Settings icon.
2. Once in System Settings, use the navigation pane (typically on the left) to scroll through the different categories (System, Display, Internet, etc.).
3. Select the section you want to change. For example, for display settings, go to Display.
   So yes — fairly straightforward.

Should I set Switch 2 to 4K or Automatic?

When you’re in TV/docked mode with a compatible display, you’ll see settings for output resolution. The question is whether to force 4K (if supported) or leave the console on “Automatic”. Here’s what sources say:

• If you’re not sure about your TV’s capabilities (HDMI version, refresh rate, etc.), setting the console’s output to Automatic is the safest choice. The Switch 2 will detect the best resolution your TV supports.
• If your TV is fully 4K capable (and you have a quality HDMI cable, reasonable refresh rate, etc.), then selecting 4K or allowing 4K output can give the best visuals — but this depends on the game: some games may not render natively at 4K and may use upscaling or be limited in performance.
  Recommendation:
• If you want convenience and worry-free setup → choose Automatic.

• • If you know your setup supports complete 4K (i.e., a good TV, HDMI 2.1, or capable HDMI ports, and you care about resolution), you can choose 4K (or manually check the Output Resolution setting).
Bottom line: Automatic is safe; 4K may give optimal visuals if your hardware supports it well.
