One way to go about this issue is to make sure that the Razer Phone has enough battery charge left. If the device screen turns on then goes to blank immediately, it means the battery must be charged longer.

Make sure that the device is indeed charging properly by looking out for the charging indicator on the screen. Note that if the battery was completely drained, it may take more than a few minutes for the indicator to appear. We recommend leaving the device to charge for at least an hour before attempting to turn it on again.

If the screen is still not turning on, the device may not be charging properly. Follow these steps:

  1. Ensure that you are using the adapter and cable that came with the Razer Phone as much as possible. Some third-party peripherals may not reach the specifications for the Razer Phone and such may not be able to charge the device correctly. Worse, using unrated peripherals may result in injury.

  2. Check for any debris blocking the charging ports and the outlet to ensure a steady power connection.

  3. Test the phone by plugging it into another power outlet or source such as a power bank.

  4. If the issue persists, remove the power adapter and attempt to charge the Razer Phone on a computer that has a USB-C port.

  5. If the phone charges successfully, the power adapter may be defective.

  6. If the issue persists, consider using a third-party USB-C charger. If that solves the issue, the USB-C cable may be defective.

Some users have also reported that the device is already powered on but cannot boot up into the Android home screen. You may try performing a hard reset on the device to restart the device. Do this by pressing and holding the Power button and the Volume up button for 7 to 10 seconds.

If the above steps do not solve your issue, consider doing a factory reset on your device. Note that, at this point, you will lose all data that you have not yet backed up. Be sure to back up your data before doing a factory reset.

To factory reset your Razer Phone, do the following:

  1. Power off the device.

  2. Enter Recovery Mode by holding the volume up and power button.

  3. Release the buttons when you see the Triple-Headed Snake logo on the buttons.

  4. Select “Wipe data/factory reset” and confirm to wipe user data.
