What standby mode does and why you might want to turn it off
Standby mode puts your device into a low-power state where the screen goes dark and most functions pause, but the device stays ready to wake up quickly. On Windows it's called Sleep, on Mac it's called Sleep, and on phones and tablets it's usually called Sleep or Lock. The device uses far less battery this way, but it's not the same as shutting down completely.
You might want to disable standby mode if you're running a long task like a file transfer or video render that you don't want interrupted, if you're using your device as a display or media player that should stay on, or if standby mode is triggering unexpectedly and waking your device at odd times. Some people also disable it temporarily while troubleshooting a problem.
Key Takeaways
- On Windows, you can prevent standby by changing power settings in Control Panel or by pressing the Windows key and typing "power settings".
- On Mac, go to System Settings > General > Lock Screen and set "Turn display off after" to Never, then adjust energy saver settings.
- On iPhone and iPad, go to Settings > Display & Brightness > Auto-Lock and choose Never.
- On Android, the method varies by manufacturer, but usually lives in Settings > Display > Screen timeout or Sleep.
- Disabling standby mode will drain your battery faster on portable devices, so consider whether you need it off all the time or just during specific tasks.
Disabling standby on Windows 10 and Windows 11
Open the Settings app by pressing the Windows key and typing "power settings". Click on "Power & battery" or "Power and sleep" depending on your Windows version. You'll see a section called "Screen and sleep" or similar. Set "Screen turns off after" to Never, and set "Sleep" to Never as well.
If you want more control, you can also access the full power plan settings. Press the Windows key, type "power plan", and click "Edit power plan". Then click "Change advanced power settings" and expand the "Sleep" section. Set "Sleep after" to Never. Click Apply and OK. This method gives you finer control if you want different behavior when plugged in versus on battery.
Disabling standby on Mac
Go to System Settings (or System Preferences on older macOS versions). Click "General" in the sidebar, then "Lock Screen". Set "Turn display off after" to Never. This prevents the display from sleeping, but your Mac may still enter a deeper sleep state.
To prevent the Mac itself from sleeping, go back to System Settings and click "General" again, then look for "Energy Saver" or "Battery" depending on your macOS version. If you see "Prevent automatic sleeping when the display is off", check that box. On newer Macs with Apple Silicon, this setting may be under "Battery" instead. These settings work differently when your Mac is plugged in versus on battery, so check both if you're using a laptop.
Disabling standby on iPhone and iPad
Open Settings and tap "Display & Brightness". Look for "Auto-Lock" and tap it. Choose "Never". This prevents your device from locking the screen and entering standby after a period of inactivity. Be aware that with Auto-Lock set to Never, your screen will stay on and drain your battery much faster.
If you only want to prevent standby temporarily — for example, while you're reading something or watching a video — you can also enable Guided Access. Go to Settings > Accessibility > Guided Access, turn it on, and then open the app you want to keep active. Triple-click the side button (or home button on older models) to lock the app in place. This is less aggressive than disabling Auto-Lock permanently.
Disabling standby on Android
The exact location varies by phone manufacturer, but the setting is usually in Settings > Display > Screen timeout or Settings > Display > Sleep. Tap it and choose the longest available option, or look for Never if your phone offers it. Some Android phones call this "Screen off timeout" or "Display timeout".
If you can't find the setting, try searching within Settings. Press the search icon at the top of Settings and type "timeout" or "sleep". Samsung phones often bury this under Settings > Display > Screen timeout. Google Pixel phones put it under Settings > Display > Screen timeout as well. Once you change it, the new setting takes effect immediately.
Preventing standby during specific tasks
If you only want to keep your device awake for a particular task, you don't have to change your power settings permanently. On Windows, you can use a free tool like Caffeine (by Zhornsoftware) or Don't Sleep, which sit in your system tray and toggle standby on and off with a single click. These are useful if you're rendering video or transferring files and don't want to dig into settings each time.
On Mac, you can hold down the Option key and click the battery icon in the menu bar to see power settings without opening System Settings. On iPhone and iPad, Guided Access (mentioned above) is the easiest temporary solution. On Android, some phones have a "Keep screen on while charging" option in Developer Options, which you can enable by going to Settings > About Phone and tapping Build Number seven times, then going back to Settings > System > Developer Options.
What to watch out for when standby is disabled
Disabling standby mode on a laptop or phone will noticeably reduce battery life. A device that normally lasts eight hours on battery might last four or five with the screen always on and standby disabled. If you're using a laptop, plug it in before you disable standby, or plan to charge it soon.
Disabling standby can also cause your device to overheat if it's in a warm environment or inside a bag. If your device feels hot to the touch, re-enable standby or give it a break. On Windows, if you disable standby and then forget about it, your device may stay on all night and drain completely, so consider setting a reminder to turn it back on when you're done with your task.
Frequently Asked Questions
Will disabling standby mode damage my device?
No. Standby mode is a power-saving feature, not a requirement for device health. Disabling it won't harm your hardware. The main downsides are faster battery drain on portable devices and slightly higher heat output, both of which are temporary and reversible.
Can I set different standby times for plugged in versus battery?
Yes, on Windows and Mac. On Windows, edit your power plan and you'll see separate settings for "On battery" and "Plugged in". On Mac, Energy Saver settings also differ between battery and power adapter modes. On phones, the setting is usually the same regardless of charging status.
What's the difference between standby and shutting down?
Standby (or Sleep) keeps your device in memory and ready to wake in seconds. Shutdown closes all programs and turns off the device completely, using almost no power but taking longer to start back up. Standby uses more power than shutdown but less than staying fully awake.
Why does my device keep waking up from standby?
On Windows, check Settings > System > Power & battery > Screen and sleep > Additional power settings > Edit plan settings > Change advanced power settings, and look for "Allow wake timers" — set it to Disabled. On Mac, check System Settings > General > Lock Screen and disable any scheduled tasks. On phones, check which apps have permission to wake your device in Settings > Apps or Notifications.
Is it safe to leave my computer on all night with standby disabled?
It's safe for the hardware, but it uses significant power and generates heat. If you need your computer to stay on overnight, consider using a scheduled task or remote access instead of disabling standby entirely. On Windows, you can use Task Scheduler to wake your computer at a specific time. On Mac, you can use Energy Saver to schedule wake times.
