Does changing the auto-off timer affect the hotspot data limit?

No. The timer only controls how long the hotspot stays on when idle. Data limits are set separately under Mobile Hotspot ➔ Configure in the same menu.

Will disabling the auto-off timer drain my battery faster?

Yes. With the timer set to Never, the hotspot keeps broadcasting even without a connected device, which uses more battery than a phone that shuts it down automatically.

Can I set a custom time instead of the default options?

The available intervals under Turn off when no device connected for are fixed choices provided by Samsung. There is no free-text field for a custom number of minutes.

Samsung: Change Mobile Hotspot Auto-Off Timer

If your Samsung phone keeps switching off the mobile hotspot after a short break in usage, the built-in 'Turn off when no device connected for' timer is doing exactly what it is set to do. By default it shuts the hotspot down after around 20 minutes without a connected device, which can cut off a laptop or smart TV mid-task. The interval can be shortened, extended, or disabled depending on how you use tethering.

Adjust Mobile Hotspot Auto-Off Timer auf Samsung

Samsung phones ship with a power-saving feature that switches off the mobile hotspot once no device has been connected for a set period. By default this window is around 20 minutes, which is enough time for a connected laptop to drop off Wi-Fi during a short pause and lose the hotspot entirely.

The setting lives inside the hotspot configuration menu, separate from the main on/off switch. Changing it does not affect data limits or the hotspot password, only the idle timeout.

Where to find the timer

Go to Settings ➔ Connections ➔ Mobile Hotspot and Tethering ➔ Mobile Hotspot ➔ Configure ➔ Advanced ➔ Turn off when no device connected for.

Pick a shorter interval to save battery faster, a longer one to keep the hotspot alive during brief disconnects, or Never to disable the auto shutoff completely. Confirm with Save to apply the change.

Disabling the timer entirely keeps the hotspot running even with no device attached, which drains the battery noticeably faster. It makes sense for a phone that stays plugged in as a stationary access point, but is less practical for everyday mobile use.

Frequently asked questions

Some devices briefly drop the Wi-Fi link during sleep mode or network switching, which the phone reads as no connection. Check the connected device's power-saving Wi-Fi settings if disconnects happen despite active use.
