1. Invisible backup battery
Your phone is running out of battery. In order to keep using it, press the *3370# key and the phone will restart. After starting, you will find that the battery has increased by 50%. You must charge this part of the hidden backup battery when you run out. When you charge again, the invisible backup battery will also be charged at the same time. You can use this method again next time the battery is low. It works very well in an emergency if the phone is low in battery.
2. Did the car remote control fall into the car?
Can your car be turned on with a remote control? If you can, one day you put the car remote control in the car and the backup remote control is at home, you will find that there is a mobile phone that is really convenient. Use the mobile phone to dial the phone and hold your phone one foot away from the car door. At the same time, the family holds the remote control and press the unlock key on the remote control next to his phone, and your car door can be opened. This method works no matter how far you drive your car from home.
3. Emergency situation
The common emergency rescue number that mobile phones around the world can call is 112. Join you and find that there is no mobile phone signal coverage in your area. At the same time, you are in an emergency situation. It is absolutely right to use your phone to call 112, because at this time your phone will automatically search for all available networks and set up an emergency call. What’s especially interesting is that even if your phone is locked in the keyboard, you can also call 112. Try it!
4. My phone was stolen?
There is a way to make the thief use it, hehe! To view the serial number of your phone, just type * # 0 6 #. 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. One day if your phone is unfortunately stolen, call the phone provider and provide your phone serial number, and they will help you block the phone so that even if the thief changes the SIM card, it still cannot be used, and your phone will become useless to the thief. If every mobile phone holder in the world does this, then stealing a phone is meaningless. In Australia, the police even established a database of stolen mobile phones, which can be returned to you if your phone is found.
Must-use for daily maintenance:
1. Do not wait until the battery of your mobile phone is out of power before charging.
Generally, we have an idea that it is better to charge the battery of the mobile phone after all the power is better, because most of the rechargeable batteries we used in the past were nickel-hydrogen (NiH) batteries, and nickel-hydrogen batteries have the so-called memory effect. If they are not discharged and charged again, they will lead to a rapid reduction in battery life. That's why we use the last drop of electricity before we start charging. 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 effects. If you wait until you have used up all the electricity, it will make the chemicals inside the lithium battery unable to react and reduce the lifespan. The best way is to charge it and keep it in the best full range anytime, anywhere, so that your battery will be available for a long time. This is the information obtained from the manufacturer and obtained through self-testing.
2. Do not answer the phone when the phone is charging! !
The reason is that when the phone is charging, there is potential danger of answering calls. There is a 31-year-old young man in India who works as a business manager at an insurance company. He answered the phone more than a dozen days ago while his phone was still connected to the charger. After a few seconds, a large amount of electric current passed through the phone. The young man was dropped to the ground. When his family found out, his fingers were burned, his heartbeat was weak, and he had lost consciousness. After being rushed to the hospital, the doctor declared dead in the hospital. Mobile phone is the most commonly used modern invention at present. However, we must also be alert to the danger of death of instruments.
3. Do not use one cell left in your phone
Compared with the full range of the message receiving system, the emission intensity is more than 1,000 times different from the time it is left. 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 phone receiving system has only one range, you would rather hang up and talk or switch to a public phone. Never talk endlessly, frolick, affectionate, unable to stop, endlessly... Why? Everyone knows The electromagnetic waves of mobile phones have always been a worrying problem. In order to maintain a considerable call quality in areas with poor reception, the design of mobile phones will strengthen the transmission intensity of electromagnetic waves. When the transmission is full and only one grid is left, the emission intensity is more than 1,000 times different. The intensity of electromagnetic waves is as high as 0.6W (watts). How strong is 0.6W? I cannot describe in detail what adverse effects it will have on your head, but you can change it to two examples to compare:
1) Turn on the volume of a small radio with a speaker diameter of about 4 cm to the maximum and stick it to the ear. The noise energy is generally 0.25W, less than 0.5W.
2) Put your finger in front of laser light with an output intensity of 0.1W (equivalent to the energy of the trunk line of the optical fiber network) and you will feel burning within a few seconds. Can you endure the above two conditions for a long time?
Then how do you confirm that the 0.6W electromagnetic wave will be fine if it is pressed against your ears?
