The Xiaomi Mi4 may sometimes get stuck in the standby mode and not even restart. This may occur due to varied problems, including installation of buggy or faulty apps, low battery, etc.
Follow the steps given below to resolve the issue:

- Turn off the device by pressing the power button.
- After it is powered off, press and hold the power and volume up buttons simultaneously till the time the phone boots into the recovery mode.
