For a period of time, the net "7 legends" made the mobile phone become a god, so the reporter verified the information on the Internet one by one.

Net pass one: mobile phone number can become empty

Enter *21*13800000000# and press Dial. When someone calls you, your call becomes an empty number. If you want to cancel, just type #21# and press Dial.

Net 2: The battery can be activated.

When the battery is low, in order to let it continue to use, press *3370#, the phone will restart, after the startup, you will find that the power is increased by 50%.

Verification: The reporter tried this method with 5 mobile phones, which proved to be invalid. According to reports, if you try this method frequently, the phone will receive an error command and cause a malfunction.

Net 3: Rebirth in the refrigerator for three days

The battery is not durable. Put the newspaper in a plastic bag and put it in the refrigerator for three days. After taking it out, charge the battery to save at least 80% of the electricity.

Verification: The phone battery is heated after being cold, and the battery is indeed higher than at low temperatures. The professional advice is: use the power meter to activate the lithium battery of the mobile phone battery when the battery life of the mobile phone becomes shorter.

Net pass four: Eraser contact can solve power failure
