Can I sleep with iqoo mobile phone without answering the phone?

After the sleep mode is started, during the period of 0-6 o'clock or 23:30-7:00 in the middle of the night, the sleep mode will intermittently receive background messages, which will not affect the reception of telephone calls and short messages, nor will it affect the reception of messages during the day and when the bright screen is used, saving electricity and protecting sleep. Just go to phone settings-battery (more settings/smart power saving)-turn off sleep mode.
