Four hidden functions of mobile phones that few people know are tips for using mobile phones, so that your mobile phone will always have power! ! ! 1. Invisible backup battery: Your mobile phone has low power. In order to continue using it, press the *3370# key, and then press the dial button~~ The phone will restart. After the startup is completed, you will find that the battery power has increased. 50%. When this part of the hidden backup power is used up, you have to charge it. When you charge it again, the invisible backup battery will also be charged at the same time. You can use this method next time the power is low. Knowing this can be very useful in an emergency if your phone is low on battery. . . 2. Did you leave the car remote control in the car? Can your car be opened with a remote control? If possible, if you leave your car remote control in the car one day and the spare remote control is at home, you will find it very convenient to have a mobile phone. You can use your mobile phone to call the mobile phones of family members and hold your mobile phone away. One foot away from the car door, and at the same time, the family member holds the remote control next to his mobile phone and presses the *** button on the remote control, and your car door can be opened here. This method works no matter how far away from home you drive. 3. In case of emergency, the same emergency rescue number that can be dialed by mobile phones around the world is 112. If you find that there is no mobile phone signal coverage in the area where you are, and you encounter an emergency, use your mobile phone to dial 112. Wrong, because at this time your mobile phone will automatically search all available networks and establish an emergency call. What's particularly interesting is that you can still dial 112 even if your phone is locked. Give it a try! 4. The phone was stolen? There is a way that even thieves can’t use, hehe! To check the serial number of your mobile phone, just type * # 0 6 #, and the 15-digit serial number will appear on the phone screen. Every mobile phone in the world has a unique serial number. Record this serial number and save it. . If your phone is unfortunately stolen one day, call your phone provider and provide your phone's serial number. They will help you block your phone so that even if the thief changes the SIM card, it still cannot be used and your phone will be blocked. Becomes useless to a thief. If every cell phone owner in the world did this, there would be no point in stealing the phone. In Australia, the police have even established a database of stolen mobile phones. If your phone is found, it can be returned to you. Must-use items for daily maintenance: 1. Don’t wait until the mobile phone battery is dead before charging. Generally, we have an idea that it is better to discharge all the battery power of the mobile phone and then recharge it. This is basically correct, because most of the rechargeable batteries we used in the past were nickel-metal hydride (NiH) batteries, and nickel-metal hydride batteries have so-called The memory effect will cause the battery life to be rapidly reduced if it is not discharged and recharged. That’s why we use the last drop of electricity before starting to charge. However, most of today's mobile phones and general IA products use lithium (Li) batteries, and lithium batteries do not have the problem of memory effect. If you still wait until all the electricity is used up before recharging, the chemical substances inside the lithium battery will not be able to react and the lifespan will be shortened. The best way is to charge it when you have nothing to do and keep it in the best full condition anytime and anywhere, so that your battery can be used for a long time. This is information obtained from the manufacturer and obtained through own testing. 2. Do not answer the phone when the phone is charging! ! The reason is that it is potentially dangerous to answer incoming calls while the phone is charging. There is a 31-year-old business manager in an insurance company in India. A dozen days ago, he answered a call while his mobile phone was still connected to the charger. After a few seconds, a large amount of current passed through the mobile phone, and the young man was thrown to the ground. His family When he was found, his fingers were burned, his heartbeat was weak, and he was unconscious. After being rushed to the hospital, the doctor declared him dead on arrival. Mobile phones are the most commonly used modern invention nowadays. However, we must also be aware of the dangers of instrument-induced death.

3. Do not use the phone when there is only one bar left. Compared with when there is only one bar left, the emission intensity is more than 1000 times different. So... people who often talk about mobile phones... should pay attention... ^0^, yesterday I got a very important message from a mobile phone dealer, that is, when you find that the reception strength of your mobile phone is only one bar, you would rather hang up or use a public phone instead. Don't talk anymore. Absolute, foaming at the mouth, full of love, can't stop, endless... Why? Everyone knows that the electromagnetic waves of mobile phones have always been a concern. And mobile phones are designed to still operate in areas with poor reception. Being able to maintain considerable call quality will enhance the electromagnetic wave emission intensity of the mobile phone. When the reception is full and there is only one bar left, the emission intensity is more than 1000 times different. The electromagnetic wave intensity is as high as 0.6W (Watt). What is the meaning of 0.6W? How strong is it? I can't describe in detail what adverse effects it will have on your head, but I can compare it with two examples: 1) Turn up the volume of a small radio with a speaker diameter of about 4 centimeters to the maximum and put it against your ear , such noise energy is generally 0.25W, less than 0.5W. Put your finger in front of a laser light with an output intensity of 0.1W (equivalent to the ?D trunk energy of an optical fiber network) and you will feel a burning sensation within a few seconds. Can you endure the above two conditions for a long time? ) Then you And how to confirm that it will be fine if the 0.6W electromagnetic wave is pressed against your ears? 4.12593 phone number = trap. Did you store the phone number of your out-of-town friend in the phone book in the format of 17951 phone number? Instead of dialing it separately? So The charge will change from 0.39 yuan per minute to 1.3 yuan per minute. I also checked with 1860 and their explanation is that if it is stored in the phone number book, the system will not be able to recognize it. Therefore, you cannot get the tariff discount and you must press 12xxx directly on the keyboard every time. Is this the case for Chinaxing users? It’s the same for M-Zone users and GSM. If you are a China Mobile user, when you know that China Mobile has set up the following traps for you, you will no longer be surprised why your phone bill will fly away as if it has wings. You can get a discount by using the 12593 phone number, but if you save the "12593 phone number" in the phone book of your mobile phone in advance, call it up when you use it, and then make calls, China Mobile will not recognize that you have used the preferential dialing method of 12593. , and billed according to the direct dialing method. If you are roaming, the difference between the two billing methods can be as much as 7 times! When I learned about such billing, I really didn’t know how to express my anger. Later, when I called 10086 for consultation, the lady with job number 6608 would not have told me about such billing unless I took the initiative to ask this question. . 5.

According to a China Mobile staff member, in fact, when you call When it reaches 0:55, it is already counted as one minute, so the call time from 0:55 to 1:00 is actually counted as 2 minutes of your money~ 7.
