What should I do if my mobile phone is temporarily out of power in the middle of the night or when I am traveling outside?

Your mobile phone battery is low. To keep it in use, press the *3370# key and the phone will restart. After starting, you will find that the power has increased by 50%. When this hidden spare battery runs out, you have to charge it. When charging, the invisible backup battery is also charged at the same time, and this method can be used next time the power is low. If the battery of the mobile phone is low, it is very useful to know this in an emergency.

2. Emergency situation

The emergency number that can be dialed by mobile phones all over the world is 1 12. If you find that there is no mobile phone coverage in your area, it is correct to dial 1 12 with your mobile phone in case of emergency, because the mobile phone will automatically search all available networks and set up an emergency call. What's particularly interesting is that you can still dial 1 12 even if your phone is in the keyboard lock state. Give it a try!

3. The mobile phone was stolen?

There is a way that thieves can't use, hehe! To view the serial number of the mobile phone, just enter * # 0 6 # and the serial number of 15 will appear on the screen of the mobile phone. Every mobile phone in the world has a unique serial number. Record the serial number and save it. One day, if your mobile phone is unfortunately stolen, call the mobile phone provider and provide your mobile phone serial number, and they will help you shield your mobile phone, so that even if the thief changes the SIM card, it still cannot be used, and your mobile phone will become useless to the thief. If every mobile phone holder in the world does this, there is no point in stealing mobile phones. In Australia, the police even set up a database of stolen mobile phones. If you find your mobile phone, you can return it to you.

Necessary for routine maintenance:

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.

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 Mobile was forced to launch a new service on 3. 15. If you are a mobile phone user of China Mobile, enter the number "0000" and send a message to 10086. Within a few seconds, you 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 will deduct your mobile phone fee by stealth. 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 tell you, let your hand function 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%).

This information was revealed by engineers from well-known battery manufacturers, and it is quite effective according to friends who have tested it.

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!
