When your RealMe 16 refuses to wake up from sleep, the screen stays black even though the phone is powered on. This can make it feel like the device is frozen or completely dead. In most cases, the issue is caused by display settings, power management features, or temporary system glitches, all of which can be fixed with a few practical steps.
Why Your RealMe 16 Won’t Wake Up From Sleep
- The power key or double-tap-to-wake feature is not responding properly.
- Battery optimization is aggressively putting the system into deep sleep.
- A temporary software glitch is preventing the display from turning on.
- The screen timeout or sleep settings are misconfigured.
- A recent update introduced a bug affecting the lock screen or display.
1. Force Restart the Phone
A force restart refreshes the system and clears temporary glitches that can stop the screen from waking. This is the first thing to try when the phone appears unresponsive.
Press and hold the Power key and the Volume Down key at the same time.
Keep holding both keys until the RealMe logo appears on the screen.
Release the keys and wait for the phone to fully boot.
2. Check Screen Wake Settings
If the screen does not wake when you tap or press the power key, the wake settings may be disabled. Re-enabling them ensures the display responds correctly after sleep.
Open Settings, and then tap Home screen and Lock screen.
Tap Wake screen, and then enable Double tap to wake or Raise to wake.
Lock the phone and test if the screen turns on normally.
3. Disable Aggressive Battery Optimization
Battery-saving features can sometimes put the phone into a deeper sleep than intended. This can delay or block the screen from waking instantly.
Open Settings, and then tap Battery.
Tap App battery management, and then disable any aggressive power-saving mode.
Restart the phone and test the screen wake behavior again.
4. Increase Screen Timeout
A very short screen timeout can cause the display to turn off too quickly and feel unresponsive. Adjusting it gives the phone more time before entering sleep.
Open Settings, and then tap Display and brightness.
Tap Screen timeout, and then choose a longer duration.
Lock the phone and check if it wakes up consistently.
5. Check for System Updates
Software bugs affecting the display or lock screen are often fixed through updates. Installing the latest version can resolve wake-related issues.
Open Settings, and then tap About phone.
Tap Software update, and then check for available updates.
Install the update if one is available and restart the device.
6. Test the Power Key
If the screen only wakes occasionally, the power key itself may be failing. Testing other wake methods helps confirm whether this is a hardware issue.
Try waking the phone using double-tap or lift-to-wake features.
Press the Power key several times to see if the response is inconsistent.
If the issue continues, professional repair may be needed.
A RealMe 16 that will not wake up from sleep is usually dealing with a software or settings issue, not a serious hardware failure. Once the system is refreshed and power restrictions are adjusted, the screen should respond normally again.
FAQs
Why does my RealMe 16 wake up only after several seconds?
This usually happens when battery optimization is delaying background processes. Disabling aggressive power-saving features often fixes the delay.
Can a faulty power key cause this problem?
Yes. If the screen wakes using tap or motion but not the Power key, the button may be worn or damaged.
Will resetting the phone fix wake-up issues?
A full reset can help if the issue is caused by deep software corruption, but it should only be used after trying all other troubleshooting steps.
