Charging your iPhone wirelessly can be bad for battery life

Wireless charging is one of the great innovations that incorporated the iPhone X and iPhone 8 , although it was not perfect: not even Apple integrates a charger - pending the launch of AirPower imminently planned - nor is anything fast.

But the small print of this feature is still worse: according to Adrian Kingsley-Hughes of ZDNet , the batteries of the iPhone would discharge faster when they are charged wirelessly than when they are charged in the traditional way.

Is that possible? As explained by Kingsley-Hughes, if we listen to Apple , " the battery of the iPhone is designed to retain 80% of its capacity during at least 500 full cycles of charging ."

And how much is this in time? Obviously it is not something uniform, but the more the battery degrades, the faster you have to reload it . But it could quietly be 2 to 3 years, taking into account previous experience with other iPhone models.

Very well, according to the experience of the ZDNet editor, in less than 6 months he has completed 135 load cycles , at this rate, he will reach 450 loads in a year and a half and 500 in about 20 months. According to the author, he does not have any app specially "devour-batteries" installed, although we already know that some applications like YouTube have had management problems or that even iOS 11 was not very efficient in this sense at the beginning.

What has changed in your iPhone usage habits? Now charge your iPhone wirelessly. It is not the first to be alerted by this, other Android users would also have discovered that the inductive load is not as healthy for the battery of their devices.

Why charging your iPhone wirelessly is worse for the battery

Adrian Kingsley-Hughes thinks he has the answer: when we charge the iPhone with the cable, the phone feeds the current precisely through the charger, but when we do it with wireless charging, it is the battery that powers the iPhone. That is, the current is fed to the charging Dock, the charging Dock feeds the battery and finally the battery supplies the phone with electricity. As a result we have a less efficient and more damaging charge for the battery life .

In addition many of us leave the phone connected even when it has reached 100%, a habit that is harmless with the cable but with the inductive charging Dock has an even greater impact on the deterioration of the battery.

However, it would be interesting to implement some function in the wireless chargers that deactivated them when the full charge has been reached , so that the deterioration of the battery is minimized.

Kingsley-Hughes has it clear: as an intensive user of his iPhone, he returns to the cable . Others will continue to take advantage of this useful feature and will soon consider replacing the battery with the cost that this entails when Apple's active replacement plan ends.

Maybe it's time for all of us who have been using wireless charging for months to check the state of our battery and take action. It's all a matter of posing it: is it worth the wireless charge even if it deteriorates the battery faster than the traditional one?
