Tips for daily maintenance of mobile phones
1. Don't wait until the battery is dead before charging.
Generally, we have an idea that it is best to recharge the battery of mobile phone after it is fully discharged. Basically, this is the case, because most of the rechargeable batteries we used in the past are nickel-hydrogen batteries, which have the so-called memory effect. If they are not fully discharged and recharged, the battery life will be rapidly reduced. That's why we started charging with the last drop of electricity. Nowadays, most mobile phones and general IA products use lithium (Li) batteries, and there is no memory effect problem in lithium batteries. If the battery is completely used up before recharging, the chemicals inside the lithium battery will not react and the service life will be shortened. The best way is to charge it when you have nothing to do, and keep it in the best full state anytime and anywhere, so that your battery can last for a long time. This is the manufacturer's information, and I have tested it myself.
2. Don't answer the phone when the phone is charging! !
The reason is that it is potentially dangerous to answer the phone when the phone is charging. There is a 3 1 year-old young man in India who works as a business manager in an insurance company. 10 days ago, he answered the phone when the phone was still connected to the charger. After a few seconds, a lot of current passed through the mobile phone, and the young man was thrown to the ground. When the family found out, their fingers were burned, their heartbeat was weak and they were unconscious. After being rushed to the hospital, the doctor pronounced him dead. Mobile phone is the most commonly used modern invention at present. However, we should also be alert to the danger of instrument death.
Don't use the mobile phone when there is only one battery left.
Compared with only one cell left, the difference of transmission intensity is more than 1000 times. So ... people who often talk about mobile phones should pay attention ... 0. I got a very important message from a mobile phone manufacturer yesterday, that is, when you find that your mobile phone reception intensity is only one frame, you would rather hang up or switch to a public phone. Don't like to talk, foaming at the mouth, affectionate, endless ... Why? As we all know, the electromagnetic wave of mobile phones has always been a worrying problem. The design of the mobile phone will enhance the electromagnetic wave emission intensity of the mobile phone, so as to maintain a fairly high call quality in areas with poor reception. When the reception is full and there is only one cell left, the transmission intensity difference exceeds 1000 times. The electromagnetic wave intensity is as high as 0. 6W (watt). 0。 How strong is 6W? I can't describe in detail what bad effects it will have on your brain, but I can compare it with two examples:
1) Turn up the volume of the small radio with a horn with a diameter of about 4 cm and stick it to your ear. Noise energy is usually zero. 25W, less than 0. 5W .
2) Put your finger where the output intensity is 0. In front of 1W laser beam (equivalent to optical fiber network? You will feel burning pain in a few seconds. Can you stand these two situations for a long time?
Then how do you confirm 0? Will the electromagnetic wave of 6W stick to your ear?
4。 12593+ phone number = trap
Do you keep the phone numbers of foreign friends in the phone book in the format of 1795 1+ phone numbers? Instead of dialing alone? Then the charge will go from zero 39 yuan becomes 1 per minute. Every minute, 3 yuan. I also checked with 1860. Their explanation is, if it is stored in the phone book? The system will not recognize it. So you can't get the preferential tariff. You must press 12xxx directly on the keyboard every time. Are all users of Shenzhouxing like this? M-zone users, so is GSM. If you are a mobile user in China, when you know that China Mobile has set the following trap for you, you won't be surprised why your phone bill flies away like a wing. You can get a discount by using 12593+ phone number, but if you save "12593+ phone number" in the phone book of your mobile phone in advance, dial it out when you use it, and then dial it out. At this time, China Mobile will not admit that you have used the preferential dialing method of 12593, but will charge according to the direct dialing method. If it is roaming, the difference between the two charging methods can be as high as 7 times! I really didn't know how to express my anger when I learned about this charge. Later, when I called 10086 for consultation, if I hadn't asked this question on my own initiative, the lady whose work number is 6608 didn't tell me about this charge at all.
5, the parasite of mobile phone fee
The mobile phone is inexplicably set with useless text messages. I strongly recommend that you see if you have been recruited. The easiest way is to unsubscribe from the parasite who steals your mobile phone bill every month! China's moving speed is 3. 15 was forced to launch a new service. If you are a mobile phone user of China Mobile, enter the number "0000" and send a message to 10086. Within a few seconds, it will automatically reply to a short message list, showing which short message services you have subscribed to on your mobile phone and which short message service providers deduct your mobile phone fee every month. Type the number "00000" and send a short message to 18620 1 to unsubscribe from all short message services.
6. Don't rush to make up 1 minute.
When we are on the phone, we are often glad that we finished the call just before 1: 00, but this is not the case. According to a staff member of China Mobile, the call to 0: 55 is actually one minute, so the call time from 0: 55 to 1: 00 is actually two minutes for you ~
7. When water enters the mobile phone, please remember not to press any button, especially to turn it off (when you press any action, the water will immediately flow with the circuit board). The correct way is to open the cover immediately, take off the battery directly, and force the power off directly, so as to protect the motherboard from water.
This common sense is very important, so I will tell you to make your hand work for a long time. Learn! In case of future emergencies!
8. How to bring the mobile phone battery back to life?
When the battery life of your mobile phone becomes shorter (memory effect or aging), will you buy another battery to replace it?
Please save your money and tell you a very effective method next time you encounter this situation. Give it a try:
1) Wrap the battery in newspaper, then put it in a plastic bag and put it in the freezer for three days (the newspaper can absorb excess water).
2) Take it out after three days and leave it at room temperature for two days.
3) After two days, charge the battery and put it into the mobile phone for testing (estimated to save 80%-90%).
The news was revealed by engineers from well-known battery manufacturers. According to friends who have tested it, the effect is quite effective.
As for whether it works or not, the battery is almost useless anyway, and everyone has a refrigerator. Friends might as well give it a try!
9. Give your mobile phone a CPR!
Does the mobile phone often run out of power? Or is it fully charged and then dead?
I must wonder if the life of the mobile phone is over.
Don't worry, it's just a temporary "cardiac arrest". Just a little eraser can bring it back to life!
After taking out the battery, clean the contacts (brass sheets) on the battery with an eraser and put them back on the phone. You will find it really amazing! It really came back to life! It looks like a new one!
