What standby mode does and why you might want to turn it off
Standby mode is a low-power state where your device stays on but uses much less electricity — the screen goes dark, the hard drive stops spinning, and most processes pause. Your device is not fully shut down, so it wakes up quickly when you touch the keyboard, move the mouse, or press a button. It is different from sleep mode (which uses even less power) and hibernation (which saves everything to disk and powers down almost completely).
You might want to disable standby if your device needs to stay active while you are away — for example, if you are downloading a large file, streaming video to another device, or running a backup. You might also disable it if standby is interfering with work you are doing, like a presentation that keeps dimming the screen. Some people disable it because they find the wake-up delay annoying, though that is usually faster than you expect.
Turning off standby does not mean your device stays at full power all the time — you can still manually put it to sleep or shut it down. Disabling standby just removes the automatic timeout that triggers it after a period of inactivity.
Key Takeaways
- Standby mode is an automatic low-power state triggered after your device sits unused for a set time, and you can change or disable that timeout in your power settings.
- On Windows, you adjust standby through Settings > System > Power & battery or through the Control Panel power plan; on Mac, it is System Settings > General > Login Items or Energy Saver.
- On iPhones and Android phones, you cannot truly disable standby, but you can extend the screen timeout or use a "keep screen on" setting in specific apps.
- Disabling standby increases battery drain on laptops and phones, so consider whether you need it off all the time or just during specific tasks.
- If you want your device to stay awake only during certain activities, most operating systems let you set different power plans or use app-specific settings instead of disabling standby globally.
How to disable standby on Windows
On Windows 10 and 11, the fastest route is through Settings. Open Settings, go to System > Power & battery (or System > Power on older versions), and look for "Screen and sleep" or "Sleep". You will see a dropdown for "When plugged in, put my device to sleep after" — set this to Never. If you are on battery, there is usually a separate setting for that; set it to Never as well if you want standby disabled in both cases.
If you want more control, use the Control Panel instead. Search for "power plan" in the Windows search box, click "Edit power plan", then click "Change advanced power settings". Look for "Sleep" in the list, expand it, and set both "Sleep after" values to Never. This method also lets you control what happens when you close the laptop lid — you can set it to do nothing instead of triggering sleep.
Keep in mind that disabling standby on a laptop will drain the battery much faster if you are unplugged. Many people create two power plans — one with standby disabled for when they are plugged in, and one with a short timeout for battery use. You can switch between them quickly from the battery icon in the system tray.
How to disable standby on Mac
On macOS, go to System Settings > General > Login Items (on newer versions) or System Preferences > Energy Saver (on older versions). Look for the "Computer sleep" slider and drag it all the way to Never. You can also set the display sleep timeout separately — that controls when the screen goes dark without putting the whole computer to sleep.
If you want the screen to stay on but the computer to sleep after a period, set "Computer sleep" to your preferred time and "Display sleep" to Never. This is useful if you want to save power but keep your device responsive.
On Mac laptops, closing the lid usually triggers sleep regardless of your settings. To prevent that, go to Energy Saver and uncheck "Put hard disks to sleep when possible" if you want the drive to stay active, though this will also increase battery drain.
How to handle standby on iPhones and Android phones
You cannot truly disable standby on iPhones or Android phones — the operating system will always dim the screen and eventually lock the device to save battery. However, you can extend the timeout before it happens. On iPhones, go to Settings > Display & Brightness > Auto-Lock and choose a longer time, up to 5 minutes. On Android, go to Settings > Display > Screen timeout and select your preferred duration.
If you need the screen to stay on during a specific task — like following a recipe or a navigation app — most apps have a built-in "keep screen on" option. In the app settings or during use, look for a toggle that says "Keep screen on" or "Prevent screen lock". This overrides the system timeout only while that app is active.
For longer periods where you need your phone awake, enable Developer Mode (on Android: Settings > About Phone > tap Build Number seven times; on iPhone: Settings > Privacy > Developer Mode) and use a "Stay Awake" option if available. On Android, you can also use third-party apps from the Play Store that keep the screen on, though these drain battery quickly and are best used only when plugged in.
When to use app-specific settings instead of disabling standby globally
Rather than turning off standby for your entire device, consider using app-specific settings if you only need it off during certain activities. Many apps — video players, navigation apps, fitness trackers, and presentation software — have their own "keep screen on" toggle. This way, standby still protects your battery during normal use but stays disabled only when you need it.
This approach is especially useful on phones and laptops where battery life matters. You get the power savings of standby most of the time, but the screen and device stay active when you are actually using them for something that requires it. It also means you do not have to remember to re-enable standby when you are done.
What happens if you disable standby and forget to turn it back on
If you disable standby on a laptop and forget to re-enable it, your battery will drain noticeably faster — sometimes two to three times as fast, depending on what your device is doing in the background. On a desktop computer plugged into power, there is no real downside, though your electricity use will be slightly higher.
If you disable standby on a phone, the battery drain is significant because the screen and processor stay active. Most people who disable it do so only temporarily for a specific task, then turn it back on. If you find yourself regularly disabling standby, consider whether a specific app setting would work better, or whether you actually need the device to stay awake that often.
Frequently Asked Questions
Is standby mode the same as sleep mode?
No. Standby uses more power than sleep — the device is more responsive but drains battery faster. Sleep is deeper and uses less power, but takes slightly longer to wake up. Hibernation is the deepest state and saves everything to disk before powering down almost completely.
Will disabling standby make my device faster?
No. Standby does not slow down your device when you are using it. The only difference you might notice is that your device wakes up when ready instead of taking a second or two, but that delay is usually imperceptible. The real trade-off is battery life, not speed.
Can I disable standby only when my laptop is plugged in?
Yes. On Windows, you can set different power plans for plugged-in and battery modes. On Mac, the Energy Saver settings explore to both, but you can manually adjust them depending on whether you are plugged in. This is the best approach if you want standby off at your desk but on while traveling.
What if I disable standby and my device overheats?
Overheating from disabled standby is rare, but if it happens, your device is probably running a background process that uses a lot of power — like a large read or video encoding. Check what is running in Task Manager (Windows) or Activity Monitor (Mac) and close unnecessary programs. Then re-enable standby to let the device cool down during idle time.
Do I need to restart my device after changing standby settings?
No. Changes to power settings take effect when ready. Your device will use the new standby timeout the next time it would normally enter standby.
