Wireless charging for cell phones is an environmental “disaster”, study finds


A study by technology-specialized portals OneZero and iFixit, there is an “environmental cost” behind the popular wireless charging for cell phones.

Wireless charging has been on the market for a couple of years as a promising new way to prevent long-term damage to terminal connections.

Despite this, research determined that beyond the appeal of wireless chargers, there is a serious power problem that has been ignored all this time.

“The slight convenience of running your phone by placing it on a pad rather than plugging it in has a surprisingly robust environmental cost,” says the study.

And it is that the process with which these types of chargers work does not allow all the energy to reach the phone, which is a loss in the process.

“Not all the energy that comes out of an outlet ends up in the phone’s battery. Some of it is lost in the process as heat.”explains OneZero.

For this reason, wireless charging uses almost more than half the energy of a wireless charger, which is both environmentally friendly and economical for the user.

“Charging the phone from completely dead to 100% with a cord took an average of 14.26 watt-hours (Wh). Using a wireless charger took, on average, 21.01 Wh. That equates to a little over 47% more power for the convenience of not connecting a cable “says the study.

But this is not the only problem, as OneZero also determined that each phone must be located millimetrically to charge in an ideal way, that is, not placing it correctly could require much more energy.

The portal said that the more wireless charging devices are used, the greater the energy impact.

“If everyone in the world switched to wireless charging, it would have a measurable impact on the global power grid,” the research says.
