Wireless Charging Is A Disaster Waiting To Happen by skyhighweb1: 9:01pm On Aug 16, 2020 |
Wireless charging is increasingly common in modern smartphones, and there’s even speculation that Apple might ditch charging via a cable entirely in the near future. But the slight convenience of juicing up your phone by plopping it onto a pad rather than plugging it in comes with a surprisingly robust environmental cost. According to new calculations from OneZero and iFixit, wireless charging is drastically less efficient than charging with a cord, so much so that the widespread adoption of this technology could necessitate the construction of dozens of new power plants around the world. (Unless manufacturers find other ways to make up for the energy drain, of course.) On paper, wireless charging sounds appealing. Just drop a phone down on a charger and it will start charging. There’s no wear and tear on charging ports, and chargers can even be built into furniture. Not all of the energy that comes out of a wall outlet, however, ends up in a phone’s battery. Some of it gets lost in the process as heat. While this is true of all forms of charging to a certain extent, wireless chargers lose a lot of energy compared to cables. They get even less efficient when the coils in the phone aren’t aligned properly with the coils in the charging pad, a surprisingly common problem. To get a sense of how much extra power is lost when using wireless charging versus wired charging in the real world, I tested a Pixel 4 using multiple wireless chargers, as well as the standard charging cable that comes with the phone. I used a high-precision power meter that sits between the charging block and the power outlet to measure power consumption. In my tests, I found that wireless charging used, on average, around 47% more power than a cable. Charging the phone from completely dead to 100% using a cable took an average of 14.26 watt-hours (Wh). Using a wireless charger took, on average, 21.01 Wh. That comes out to slightly more than 47% more energy for the convenience of not plugging in a cable. In other words, the phone had to work harder, generate more heat, and suck up more energy when wirelessly charging to fill the same size battery. How the phone was positioned on the charger significantly affected charging efficiency. The flat Yootech charger I tested was difficult to line up properly. Initially I intended to measure power consumption with the coils aligned as well as possible, then intentionally misalign them to detect the difference. Instead, during one test, I noticed that the phone wasn’t charging. It looked like it was aligned properly, but while trying to fiddle with it, the difference between positions that charged properly and those that didn’t charge at all could be measured in millimeters. Without a visual indicator, it would be impossible to tell. Without careful alignment, this could make the phone take way more energy to charge than necessary or, more annoyingly, not charge at all.

Lexusgs430: That's why it's important to always check the voltage of chargers before you buy them. Most phones are rated to have 5 Volts. This means that your charger should also be within this range. Else, you'd risk your device burning due to short-circuit caused by fluctuating voltage. 1 Like |

Saw this on YouTube, laterclips or Lew later can remember which ,these are but perks of a new technology, and as all technologies, improvements come as years go by, you can't just dump it cos of these 'little' challenges, in years to come, there would be more power efficiency in charging wirelessly. Just give it time. |

I think the spread of wireless charging is quite inevitable with time, but before then let's cherish what we have in devices like the Pouvoir 4 that has a battery capacity to last to last you very long just with one charge |
Re: Wireless Charging Is A Disaster Waiting To Happen by Corroro: 5:12pm On Aug 23, 2020 |
as far as technology is concerned, wireless charging will definitely come to stay, its more of a evolution |
Re: Wireless Charging Is A Disaster Waiting To Happen by Corroro: 5:13pm On Aug 23, 2020 |
