The secret in the mobile phone: not in the mobile phone
After using mobile phones for so long, no matter whether it is adults, children or the elderly, everyone has a mobile phone, and there are high-end resistors, but do you know the hidden secrets in mobile phones? Here are 14 secrets you must know about mobile phones.
1. Don't rush to end the call in exactly 1 minute
When we make phone calls, we often feel fortunate to end just before 1:00, but that's not the case. According to a China Mobile staff member, in fact, when you call at 0:55, it's already a minute, so the call time from 0:55 to 1:00 is actually your 2 minutes!
2. Teach you how to get rid of phone screen scratches
Do you often encounter scratches on the screen of your mobile phone and don't know how to deal with them? Let me tell you a useful secret recipe. Squeeze an appropriate amount of toothpaste on a damp rag and apply it vigorously back and forth around the scratches on the screen of your mobile phone. You will find that the screen scratches of your mobile phone will disappear as a result. It's amazing! What's even more amazing is that after wiping it clean with a clean rag or toilet paper, the screen of your mobile phone will become brighter.
The principle is that toothpaste is just an auxiliary product for brushing teeth, which has a friction effect (repair effect) and removes plaque, cleaning and polishing teeth, so it will have the same effect when used on the mobile phone screen.
3. Invisible backup battery
Your phone is low on battery. In order for it to continue to be used, press the * 3370 #button and the phone will restart. After starting, you will find that the battery has increased by 50%. When this part of the hidden spare power is used up, you have to charge it. When charging again, the invisible spare battery is also charged at the same time. You can use this method again when the battery is low next time. Know this is very useful in an emergency if the phone is low on battery.
4. The car remote control is left in the car
Can you open your car with a remote control? If so, one day you leave the car remote control in the car and the spare remote control is at home, you will find that it is very convenient to have a mobile phone. Use the mobile phone to dial the mobile phone of the family member, hold your mobile phone one foot away from the car door. At the same time, the family member holds the remote control and presses the unlock button on the remote control next to his mobile phone, and your car door can be opened here. This method works no matter how far you drive the car from home. (Someone has tried it for himself, it is very effective, and it is amazing.)
5. Emergency situations
The common emergency number that mobile phones around the world can dial is 112. If you find yourself in an area with no cell phone coverage, and you encounter an emergency situation, it is correct to dial 112 from your mobile phone, because at this time your mobile phone will automatically search all available networks and establish an emergency call. What's especially interesting is that you can still dial 112 even if your phone is locked with the keyboard. Try it!
6. The phone was stolen
There is a way for thieves to use it, hehe! To check the serial number of the mobile phone, just type * #0 6 #, and the 15-digit serial number will appear on the mobile phone screen. Every mobile phone in the world has a unique serial number. Record and save this serial number.
One day if your phone is unfortunately stolen, call the phone provider and provide your phone serial number, they will block the phone for you, so that even if the thief changes the SIM card, it still cannot be used, and your phone becomes useless to the thief. If every phone owner in the world does this, there is no point in stealing the phone.
7. Don't wait until the phone battery is out of power to charge.
Generally, we will have an idea that the battery power of the mobile phone should be fully discharged and the booster charge is better. Basically, it is correct, because most of the rechargeable batteries we used in the past are nickel-metal hydride (NiH) batteries, and nickel-metal hydride batteries have the so-called memory effect. If it is not discharged and recharged, it will cause the battery life to decrease rapidly. Therefore, we will use the last drop of electricity to start charging.
But most of today's mobile phones and general IA products use lithium (Li) batteries, and lithium batteries have no memory effect problem. If you still wait until all the power is used up before charging, it will make the chemicals inside the lithium battery unable to react and reduce its lifespan. The best way is to charge it when you have nothing to do to keep it in the best full condition anytime, anywhere, so that your battery can last long and long. This is the information from the manufacturer and tested by itself.
8. Do not answer the phone when the phone is charging
The reason is that the phone is charging, and there is a potential danger if you answer an incoming call. There is a 31-year-old business manager in an insurance company in India who answered the phone more than ten days ago when the phone was still connected to the charger. After a few seconds, a large amount of current passed through the phone. The young man was dropped to the ground. When his family found it, his fingers were burned, his heart was weak, and he had lost consciousness.
After being rushed to the hospital, the doctor pronounced him dead. The mobile phone is by far the most commonly used modern invention. However, we must also be alert to the danger of death caused by the instrument.
9. Do not use when there is one space left on the mobile phone.
When the reception is full and there is only one frame left, the transmission intensity is more than 1,000 times different, so people who often talk about mobile phones should pay attention. When you find that there is only one frame left in the reception intensity of the mobile phone, you would rather hang up or use a public phone instead. Don't talk endlessly, talk profusely, be affectionate, unable to stop, and endlessly.
Why is that? We all know that the electromagnetic waves of mobile phones have always been a concern. And the design of mobile phones to maintain considerable call quality in areas with poor reception will enhance the electromagnetic wave emission intensity of mobile phones. When the reception is full compared to only one cell, the emission intensity is more than 1000 times different. The electromagnetic wave intensity is as high as 0.6W (watts). How strong is 0.6W? I can't describe exactly what bad effects it will have on your head, but I can compare it with two examples:
① Turn on the volume of a small radio with a speaker diameter of about 4 centimeters to the maximum and then stick it to the ear. The noise energy is generally 0.25W, less than 0.5W.
② Put your finger in front of the laser light with an output intensity of 0.1W (equivalent to the D trunk energy of the optical network) for a few seconds and you will feel a burning sensation. Can you tolerate the above two conditions for a long time? Then how can you confirm that 0.6W electromagnetic waves will be fine if they stick to your ears?
10.12593 + phone number = trap
Do you store the phone numbers of your out-of-town friends in the phone number book in the format of 17951 + phone numbers - instead of dialing them separately - then the charge will change from 0.39 yuan per minute to 1.3 yuan per minute. I also checked from 10086. Their explanation is that if it is stored in the phone number book - the system will not be able to recognize it. So you can't get the tariff discount, you must press 12xxx directly on the keyboard every time. This is true for Shenzhou users! M-Zone users, the same is true for Global Connect. If you are a China Mobile user, when you know that China Mobile has set the following traps for you, you will no longer be surprised why your phone bill will fly away like wings.
You can get a discount with 12593 + phone number, but if you save "12593 + phone number" in the phone book of your mobile phone in advance, call it out when you use it, and then dial it out, then China Mobile will not admit that you have used the preferential dialing method of 12593, but will charge it directly. 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, if I didn't take the initiative to ask this question, I wouldn't have told me about such billing at all.
11. Parasites of mobile phone bills
The mobile phone has inexplicably set up useless text messages. I strongly recommend that everyone check if they have been hit. The easiest way is to unsubscribe from the parasite that steals your mobile phone bill every month! China Mobile was forced to launch a new business on 3.15. If you are a mobile phone user of China Mobile, type the number "0000" and send a text message to 10086. A text message list will be automatically replied within a few seconds, showing which text message services have been customized on your mobile phone.
Which SMS service providers explicitly and secretly deduct your mobile phone fee every month; type the number "00000" to send a text message to 186201 to unsubscribe from all SMS services.
12. The phone gets flooded
Please remember not to make any button actions, especially shutdown (as soon as you press any action, the water will immediately follow the circuit board flow string). The correct way is to open the outer cover immediately, directly remove the battery, and directly force the power off to protect the motherboard from water. This common sense is very important, so I will tell you to make your mobile phone usable for a longer time. Learn it! Be prepared for emergencies in the future!
13. How to bring mobile phone batteries back to life
When your mobile phone battery life becomes shorter (memory effect or aging), will you buy another battery to replace it? Next time you encounter this situation, please save your money and tell you a very effective method to try:
① Wrap the battery in newspaper and then put it in a plastic bag and put it in the freezer for three days (newspaper can absorb excess water)
② Take it out after three days and leave it at room temperature for two days.
③ Charge the battery after two days, and put it into the mobile phone wrap test after it is fully charged (it is estimated that 80% -90% can be saved)
14. Do a CPR on your phone.
Does the mobile phone often lose power? Or does it run out of power soon after it is fully charged? Must have doubted whether the life of the mobile phone is over? Don't worry, it just stops beating for a while, as long as a small eraser can come back to life, take out the battery and wipe the contacts (brass sheet) on the battery with an eraser, and then put it back on the mobile phone, you will find that it is amazing, it actually came to life, and it looks like a new one. It is really useful for everyone's reference!
