How to use wireless charging on your phone (without cables)

Ricarica wireless One of the most innovative features on modern phones is undoubtedly wireless charging, which allows phones to recharge the internal battery without the aid of a cable but using proximity electromagnetic wave technology. This technology has revolutionized the charging of smartphones, which in fact can now be recharged anywhere by placing the back of the phone on the appropriate charging surfaces (even in the car).

Let’s see together what is wireless charging on the phone and how to use it, assuming that the best results are obtained on phones that are born with fast charging included in the data sheet (still few in reality, but more and more phones offer this function).

What is wireless charging

As the name suggests, wireless charging allows you to recharge the battery of your smartphone without using a cable, but simply by placing the smartphone on a “recharging” surface. It is also called inductive charginggiven the type of electromagnetic technology used.

Using this technology we can therefore get rid of the stress of the cable and the possible problems generated by an intense use of the USB socket for charging (if you pull too hard, for example, you can also break the connector!).

The charging base is composed of solenoids that generate a small electromagnetic field in the area indicated for charging; this field is activated only if there is a smartphone in the area, obviously compatible with wireless charging. In the smartphone there is a small wire wound on itself capable of capturing the electromagnetic waves generated by the wireless charger.

The passage of electromagnetic waves on the wire triggers an inductive process that generates electrical energy, which can then begin to charge the battery. As soon as the smartphone is removed from the charging area, the wireless connection is disconnected without any danger. There are currently two standards for wireless charging of portable devices:

1) Qi: this is the most widespread standard, distributed by the Wireless Power Consortium (WPC).

2) PMA: another standard used for wireless charging, distributed by Power Matters Alliance.

Both standards are effective for wireless charging, only the frequencies in use and the type of connection change. In the case of the PMA standard it is possible to recharge the devices also with an external adapter, just get the inductive adapter and connect it to the USB socket, so as to recharge the smartphone without wires on the appropriate base.

Therefore, before choosing any charging base, try to find out which standard is used by the phone in use, so as to buy a compatible model.

Charging times

Wireless charging has evolved and now allows you to recharge a smartphone in just over an hour, with times therefore comparable to the standard USB cable without fast charging, although obviously a lot depends on the type of base purchased and the standard used.

On some high-end phones we also find the ricarica fast wireless, a special recharge based on high-energy electromagnetic waves capable of fully recharging the phone in less than half an hour, a time unimaginable until recently.

Smartphones compatible with wireless charging

There are more and more smartphones compatible with wireless charging, below you can find a list of the most recent models that integrate charging inside the body of the phone.

Conclusions

With wireless charging we will be able to recharge the phone battery without using the charging cable, but simply by placing the phone on the prepared charging bases, on one of the charging supports seen above or on the new generation cars, which often contain a dedicated space. wireless charging of compatible devices.

The charging speeds are not comparable to those obtainable with the USB cable, but they become faster and faster with the passage of time: it is only a matter of time before even reaching the speed of the cable.
