Wireless charging is especially convenient because you don’t need a cable for it. However, this technology is still at the very beginning of its development.

Is inductive charging bad for batteries?

Wireless charging can really harm the battery of a smartphone, as with frequent recharging, it will spend its resource faster.

The operation of inductive chargers is based on the principle of electromagnetic induction. In simple terms, two coils – one in the smartphone, the second in the memory – are located one above the other and create an electric current, due to which the phone is charged.

    How Wireless Phone Charging Works: It’s Not Magic

During charging, the coils heat up – and so that the smartphone does not overheat, battery protection is activated in it. As soon as the device replenishes the charge by 100 percent, charging stops. However, if the phone is not removed from the charger, after a while it will lose 1% and start replenishing the battery again. This causes new charging processes to start over and over again even though the phone is already fully charged, which is especially detrimental to battery performance.

Modern smartphone users seriously stress their devices by sending them to the charging station several times a day. This should not be done in any case, because too frequent charging reduces the resource (capacity) of the battery.

Try to charge the battery as little as possible. Modern smartphones are designed for about 500 charges, after which the battery power begins to decline significantly. If you charge your phone every day, that’s the equivalent of about a year and a half of comfortable use.

Wireless charging – future prospects

At present, inductive charging is still a new but very promising technology. Most likely, in a few years it will be developed so much that in every public place like a cafe or a bus stop it will be possible to charge a smartphone on a wireless charging pad.

However, today inductive chargers and smartphones with this function are more expensive than conventional models. In addition, the technology has obvious disadvantages that can only be eliminated with the development of more advanced charging stations.

The main problem with inductive charging these days is that it takes much longer than the classic cable charging process. Smartphone developers are working on this problem too – there are even wireless chargers with a performance of up to 40 watts, but the phones themselves rarely support such power. For example, the top-end Galaxy S21 can charge wirelessly with a maximum of 15W.

The main advantage of inductive charging is that thanks to it, smartphones can do without an extra outlet for connecting a cable. This will make the devices more water resistant and reduce the risk of damage to the charging port.
