How to Fix vivo X300 Pro That Won’t Wake Up From Sleep

Your vivo X300 Pro is designed to wake up instantly with a tap or power key press. But if the screen stays black and unresponsive, it can be worrying. This problem usually points to a temporary system glitch, a display timeout bug, or power-related issues.

Before assuming the worst, try these simple solutions to bring your device back to life.

Why Your vivo X300 Pro Won’t Wake Up From Sleep

• The screen timeout setting is too short.
• A system crash has frozen the display.
• Power or Sleep settings are misconfigured.
• The phone’s battery is completely drained.
• An outdated firmware or app conflict is preventing normal wake-up.

Check for Power or Battery Issues.

If your phone doesn’t respond at all, it might simply be out of power. A depleted battery can make the device appear dead even when you press the power key.

1. Plug your vivo X300 Pro into a charger, and then wait for at least 10 minutes.
2. Once the charging indicator appears, press and hold the Power key for about 5 seconds to turn it on.

If it still doesn’t respond, try using a different cable or charger to rule out a charging issue.

Force Restart the Device.

When the screen is black but you feel vibrations or sounds, the system might have frozen in sleep mode. A force restart refreshes the system and clears any stuck background process.

1. Press and hold both the Power and Volume Up keys at the same time.
2. Keep holding for around 15 seconds until the vivo logo appears, then release both keys.

After restarting, check if the phone now wakes normally with a tap or button press.

Adjust Screen Timeout Settings.

If your phone sleeps too quickly, it might seem like it’s not waking properly. Increasing the timeout duration can help.

1. Open Settings, and then tap Display and brightness.
2. Tap Screen timeout, and then select a longer duration such as 2 minutes or more.

This ensures the display stays on long enough before going back to sleep again.

Disable Adaptive Brightness.

Sometimes, the screen remains dim or black due to aggressive brightness control. Turning off Adaptive brightness ensures the screen lights up properly every time.

1. Open Settings, and then tap Display and brightness.
2. Toggle off Adaptive brightness to disable automatic light adjustment.

Now try waking the device again to check if the display turns on normally.

Update the System Software.

A software glitch might be preventing the screen from responding correctly after sleep. Installing the latest system update can fix this issue.

1. Open Settings, and then tap System update.
2. Tap Check for updates, and then follow the prompts if a new version is available.

Once updated, restart your vivo X300 Pro and see if the wake-up function works smoothly.

Reset All Settings.

If none of the fixes work, there might be a deeper configuration issue. Resetting all settings restores system defaults without deleting your data.

1. Open Settings, and then tap System management.
2. Tap Backup and reset, and then tap Reset all settings.

After the reset, check if the phone now wakes up properly from sleep.

A vivo X300 Pro that fails to wake from sleep can often be fixed with these steps. Most cases are caused by minor glitches or settings that can be quickly corrected without service center visits.
