Is wireless charging harmful to the smartphone battery?

by Shubham Khurana

Wireless charging is one of the hottest trends in the smartphone industry. The smartphone giants are now improving their products because no one wants to be in the range without such an equipped smartphone. There is no need to use annoying cables; just put your smartphone in the Qi charging station to charge the battery. Charging stations already have a variety of designs and are built into the surface. But how does wireless charging work? Is this new technology really harmless, or should I think twice before buying a smartphone with inductive charging? Especially for batteries, the new charging technology should not bring any advantages but rather disadvantages. We provide you with important information about wireless charging.

The principle of inductive charging

It's all about coils here. More precisely, there are two coils, one installed on the smartphone and the other installed on the charging station. The current flows through these coils. Therefore, if they overlap and are compatible with each other, your smartphone will charge. This is a brand new technology. Or maybe not? Anyone who owns an electric toothbrush already has wireless charging at home. Take a closer look because the toothbrush only needs to be plugged into the charging station, and it will clean your teeth with electricity the next time it is used. The most widely used wireless charging standard is called the Qi standard. This word comes from Chinese and means life energy. What a fit, because today we save a lot of time by allowing many daily functions to take away from our mobile companion, as long as we don't get distracted by social media apps, gaming apps, and business. Several vendors, including Samsung, Apple, Nokia, and Sony, have come together to create the Wireless Power Consortium. According to their own statements, there are around 850 Qi-compatible products on the market so far. In addition to the Qi standard, the Powermat technology is also suitable for inductive coupling, and the Review technology, which has a resonant magnetic coupling.

Advantages and disadvantages of inductive charging

If the technology becomes more popular, you will soon be able to place your smartphone anywhere for wireless charging. This eliminates the need to carry annoying cables. The Qi standard also allows you to use third-party products, for example as car accessories or furniture. In addition, the charging socket can also be saved; that is, the risk of malfunction of the charging socket is eliminated. In addition, if the smartphone does not require a charging socket, it is also conducive to the advancement of waterproof smartphones. Those who are aesthetically inclined will naturally like the reduced number of cables. In addition to the almost invisible charging points installed on furniture, cars, and perhaps soon in public places, there are also models such as wooden windows, small cushions or stone-like chargers. It is also good to be able to charge multiple devices at one charging station at the same time.

However, despite all the advantages, wireless charging also has disadvantages; otherwise, all smartphone manufacturers would have adjusted their entire range long ago, such as using adapters or other methods. For most devices, no matter how new the technology is, it still needs to be updated. If you want to buy a smartphone that has been equipped with a suitable one, the charging station is not included in the normal scope of supply. For different uses throughout the home and in cars and businesses, many sites are needed. The average price is $40-50, which the supplier calls a proud price. What if the protective cover is too thick? Then it must be removed before charging. Anyone who is confident in safety and therefore prefers to use bumpers has no fun here. You should not assume that inductive charging is as fast as charging with a wire. Because using the cable to charge directly provides better power for your smartphone because wireless charging is supposed to take about 50% of the time. But for all interested people, the most serious point may be the difficulty of using it when charging. Everyone should have used a mobile phone while charging. However, since the direct connection to the charging base is a basic requirement for wireless charging, it is difficult to use it as usual. We definitely recommend waiting and seeing. Several young manufacturers are still competing for the market here. It is not clear who will win. If you bet on the wrong horse, it will be very annoying. 

Risks - is wireless charging harmful to the phone battery?

In addition to the many advantages and disadvantages, there has been a lot of discussion about the risks of wireless battery charging recently. A famous technology portal studied the battery functions of the iPhone 8 and iPhone X equipped with wireless charging stations. They clearly concluded that compared with traditional wired charging, the battery is more affected here. The exciting thing is that the mobile phone will receive power during normal charging, while in wireless charging, the power still comes from the battery, and the battery is still charging. This double load charging will damage the battery, ie. Battery Life. Although many inductive charging stations have intelligently detected when the battery is fully charged, the charging process will restart once the battery level is less than 1%. This is the killer of drums. Due to our usage behaviour, we tend to put the smartphone in the charging station more than once a day as recommended. This will permanently reduce battery power. Also, even if the battery is not fully charged, the coil will heat up, activate the battery overheat protection, and then stop charging. So relying on a fully charged battery the next morning will lead to extreme disappointment.

That is why it is necessary to check who chooses wireless charging. This young technology is still in its infancy and requires a lot of money. If you don't want to change your phone's battery too quickly, you should also think twice about whether it is right for you. But in the future, there may be charging stations in public places such as trains, buses, aeroplanes, restaurant chains, and mobile phone batteries may become more powerful, so that a new step can be taken in the future. In any case, the wireless charging station looks much more beautiful than any cable, and it is definitely part of the superior design apartment.
