Android phones have a feature called Bedtime mode, which helps users improve their sleep quality by reducing distractions before bed. This mode includes a Sunrise Alarm, which wakes the user up gently by slowly brightening the screen before the alarm rings. While there is no specific sleep/wake button on Android phones, users can set up a bedtime and wake-up time, and repeat alarms for them. Users can also wake up the screen by pressing the power button, or by using the lift to wake or double-tap to wake the screen feature.

What You'll Learn
Waking up the screen without the power button
If your Android device's power button stops working, there are alternative methods to wake up the screen. Many Android phones come with built-in features that can help with this. One of the simplest ways to wake your screen is by using the Double Tap to Wake feature. This feature is available on many modern Android devices and can be found in the Settings. To enable it, go to Settings, scroll down and tap on Advanced Features, then select Motions and Gestures, and finally toggle on the Double Tap to Wake option.
If your device doesn't have this feature built-in, you can download apps like Double Tap Screen On or Off from the Play Store. These apps offer similar functionality and can be a great alternative. However, keep in mind that they may not work perfectly on all devices, and there is a chance of accidental triggers in pockets or bags.
Another way to wake your Android device without using the power button is through motion and gesture settings. Many Android phones are equipped with these features, which allow you to interact with your device in unique ways. To access these settings, go to Settings, then Advanced Features, and select Motions and Gestures. Here, you can find options like Lift to Wake, which turns on the screen when you pick up your device.
Additionally, if your phone has a physical fingerprint sensor or facial recognition feature, you can use these to wake your device without needing the power button or a third-party app. These options not only wake your phone but also bypass the lock screen. You can usually find these settings under Settings > Security or Settings > Security > Smart Lock > Trusted Face.
Lastly, some Android phones support Always On Display (AOD), which means your phone's screen never turns off and continuously shows information like the clock and notifications. This feature is usually available on devices with OLED displays, and it makes waking up your phone instant and doesn't require pressing the power button.

Using Bedtime mode
If you're having trouble falling asleep due to your phone, Android's Bedtime mode (or Sleep mode on Samsung phones) can help you improve your sleep quality by reducing distractions. The mode activates greyscale and dark modes to drain colours from your phone, blocking the visual stimulus that keeps you glued to your screen.
To set up Bedtime mode, open your Settings. Scroll up and tap Digital Wellbeing & Parental Controls. Tap Bedtime mode. Go to Bedtime routine > Use a schedule. You can also turn on the Eye Comfort Shield, Sound mode and volume, and Power Saving.
On Samsung devices, Bedtime mode is part of five modes: Driving, Exercise, Relax, and Work modes. You can set your sleep and wake-up times and repeat alarms for them every day. The feature always sets up a Do Not Disturb filter during these times to block calls, messages, and notifications.
You can also customise your notifications so that your phone will no longer make noise or vibrate. Long press the notification, go to Settings, and make it a silent notification. You can also go into the notification settings for Routines and set it to silent.

Setting a sleep and wake-up schedule
Step 1: Accessing the Clock App
To set up your sleep and wake-up schedule, start by opening the Clock app on your Android device. If you don't have the Clock app, you can download Google Clock from the Google Play Store. Once you have the app, open it and look for the "Bedtime" tab, usually located at the bottom of the screen.
Step 2: Setting Your Bedtime and Wake-Up Times
In the "Bedtime" tab, you'll find a "Schedule" card. Tap the time under "Bedtime" to set your desired bedtime and the days you want to follow this routine. You can also set a reminder notification to let you know when it's time to start getting ready for bed.
Similarly, tap the time under "Wake Up" to set your desired wake-up time and the days you want to use this alarm. You can even choose to have your screen slowly brighten 15 minutes before your alarm goes off, simulating a natural morning light.
Step 3: Customizing Your Experience
The Clock app offers various customization options to enhance your sleep experience. You can choose the alarm sound, turn on vibration, and even select a Sunrise alarm that gradually brightens your screen before your alarm goes off. Additionally, you can integrate Google Assistant to perform specific tasks when you wake up.
Step 4: Reducing Distractions
To minimize distractions and create a calm environment before bed, enable Bedtime mode. This mode silences your phone, removes the screen's color, and blocks notifications, calls, and messages. On Samsung phones, this feature is called "Sleep mode." You can also choose specific apps to block or allow during this time.
Step 5: Reviewing Your Sleep Schedule
Once you've set your sleep and wake-up schedule, take some time to review it. The Clock app will show you how much sleep you're getting each night, helping you maintain a consistent sleep schedule.
By following these steps, you can effectively set up a sleep and wake-up schedule on your Android device, promoting a healthier sleep routine and improving your overall well-being.

Deep sleep hardware buttons
The power button is the only hardware button that consistently works when an Android phone is in deep sleep mode. When the phone is asleep, there is a 90% chance that none of the other hardware buttons will work. However, some users have reported that holding the headset button for 6 seconds, then releasing and clicking it, can wake the phone from deep sleep. Additionally, it may be possible to wake the phone by pressing the volume buttons while music is playing, either through the Android Music Player or a third-party app like Winapm.
To enable hardware buttons to work during deep sleep, you can try adding "WAKE" to the relevant key in the "system/usr/keylayout/Generic.kl" file. For example, changing "key 226 HEADSETHOOK" to "key 226 HEADSETHOOK WAKE" has been reported to fix this issue for some users. Alternatively, you can try enabling debugging options to add keypresses to the logcat for further analysis.
It is worth noting that when an Android phone is in deep sleep mode, the processor is completely stopped. This means that there are no applications running in the background, which may be why hardware buttons do not work reliably during this state. However, it is still possible to start audio playback from deep sleep by using the headset button or, in some cases, the volume buttons.
While there is limited information specific to "deep sleep hardware buttons" for Android devices, it appears that the power button is the most reliable way to wake an Android phone from deep sleep. Other buttons, such as the headset button and volume buttons, may work in certain scenarios, but their functionality is not guaranteed. Modifying system files or using third-party applications might be necessary to enable or enhance the functionality of hardware buttons during deep sleep.

Lift to wake or double-tap to wake
Some Android phones have a "Lift to wake" feature, which means that the phone will automatically wake up when it is lifted out of a pocket or bag. This can be useful, as it means that the user doesn't need to swipe or tap the screen to wake the phone up. However, it can also lead to accidental activation, for example, when the phone is in a pocket or bag and the user is moving around. This can cause the phone to accidentally dial numbers or activate other features. The "Lift to wake" feature can be disabled if it is causing problems, but this may not be necessary as the phone may still be able to function properly with the feature enabled.
Another similar feature is "Double-tap to wake", which allows users to double-tap the screen to wake their device. This can be useful if the user wants to quickly check the time or notifications without having to pick up the phone. However, similar to "Lift to wake", this feature can sometimes be inconsistent and may not work all the time. In some cases, the user may need to tap the screen multiple times before the phone wakes up.
Both "Lift to wake" and "Double-tap to wake" are features that are designed to make it more convenient for users to wake their devices. However, as mentioned earlier, these features can sometimes cause accidental activations or be inconsistent in their performance. It is worth noting that these issues may be specific to certain phone models or versions of the Android operating system, and they may be addressed in future updates or with custom kernels.
To manage these features on your Android device, you can usually find them in the 'Display' or 'Gestures' settings. The exact steps may vary depending on your device manufacturer and Android version. However, by accessing these settings, you should be able to enable or disable "Lift to wake" and "Double-tap to wake" according to your preferences.
