What should I do if my mobile phone is low in power？ Inventory of mobile phone charging methods

Wechat WeChat official account: China Mobile

The pace of modern life is fast, and the mobile phone is dying without electricity. There are many ways to charge mobile phones. What is yours, my friends? Can’t you play without the data cable? Or wireless charging on the tall? Move with the small number. What’s your posture?

1、USB Type-C

The biggest advantage of USB Type-C is that both sides can be plugged in. Xiao Yi is always annoyed that the interface of the mobile phone charger must be inserted according to its interface shape. Every night, she is sleepy and has to wake up before she can plug in the charger. The file transfer speed of USB 3.1 standard interface is also improved. However, at present, many mobile phones using USB Type-C interface adopt USB 2.0 standard. Although the appearance is Type-C, the file transfer speed is the same as before, and the charging speed has not changed.

The charging speed of a mobile phone depends on the charging current limit. Under the voltage of 20V, the upper limit of USB Type-C can reach 100w, but most mobile phones are limited to 18W-24W. USB Type-C can charge quickly, but it is limited in practical use. Even if the charging speed is unchanged from the traditional one, are there some friends ready to move?

2. Wireless charging

The biggest advantage of wireless charging is convenience, just put the mobile phone on it. The disadvantage is that the charging speed is too slow, about 20% slower than the traditional interface charging, and the friends must accurately place the mobile phone on the wireless charging base to charge. The fever of the mobile phone is also obvious when charging wirelessly. In addition, the cost of wireless charging is much higher than that of ordinary chargers. Small move is yearning for this tall, it is really reluctant to give up money.

Fast charging is a great technology developed recently. Little friends may be curious. Although it is fast, what impact will it have on the battery?

If the pro’s mobile phone battery supports fast charging and uses the official charger, then the battery will not be affected by fast charging. However, if friends use fast charging to charge ordinary batteries, it will seriously damage the battery life: fast charging depends on special components on the charger and chips on the mobile phone, and the two must be matched to ensure that current can be injected into the battery quickly and safely.

4. Fast wireless charging

At present, there are not many models that support wireless charging, and even fewer support fast wireless charging, but fast wireless charging technology has both the speed of fast charging and the convenience of wireless charging. Compared with wireless charging, its charging limit can reach 15W, which is three times as fast as that of ordinary wireless charging, and its charging speed is 50% faster. But at present, only a few models on the market have this function.

Little friends are envious of wireless charging, but they are more eager for fast charging. This is not impossible. Small move to popular science, look, the new material is revealed, and the fast charging battery material-graphene.

What are the advantages of graphene?

Graphene will replace silicon and create a brand-new era for the world’s electronic technology! The charging time of graphene mobile phone is only 5 seconds, and the battery is full, which can be used continuously for half a month! The graphene battery only needs to be charged for 10 minutes, and it is possible for an environmentally friendly and energy-saving car to travel 1000 kilometers!

Graphene is a two-dimensional crystal with only one atomic thickness, which is separated from graphite and composed of carbon atoms. Graphene is both the thinnest material and the strongest material, and its breaking strength is 200 times higher than that of the best steel. At the same time, it has good elasticity, and the stretching range can reach 20% of its own size. It is the thinnest and strongest material in nature at present. If a hammock is made of graphene with an area of 1 square meter, its own weight is less than 1 mg, and it can bear a one-kilogram cat. At present, the most potential application of graphene is to become a substitute for silicon, to make ultramicro transistors and to produce future supercomputers. Using graphene instead of silicon, the computer processor will run hundreds of times faster. Think about it, friends. How about this thing instead of the cell phone battery material?

Summary: Which charging method is the best?

Xiao Yi said: It depends on the attitude of friends to the battery. If parents want to extend the battery life, I suggest you choose a traditional charger. If you want to save trouble, you can choose a wireless charger. If you only pursue speed, you can choose fast charging or USB type-C. If you are preparing to buy a new mobile phone and at the same time pursue the best charging experience (if you are not short of money), you can find out which terminal supports it.
