The wireless charging has become one of the essential aspects of premium range phones, because although the charging power still lags behind the wired charging capabilities, it is much more convenient to charge the phone just by connecting it to a base without rely on connecting and disconnecting a cable.
However the Wireless Power Consortium He had already warned for a few years that wireless charging systems were a problem, as they used much more energy to charge the battery compared to traditional charging.
A new study conducted by OneZero revealed that the Wireless Power Consortium’s estimates are correct, with a phone taking almost 50% more charge to fill a battery compared to a wired system to complete this process.
Previously, it had been concluded that the wireless charging efficiency with the Qi standard was classified as “bad” because it had achieved 59.4%, that is, it basically required more than half the energy to charge a battery.
The folks at OneZero revealed that their tests used a Pixel 4 with different wireless chargers with the Qi standard, which were directly compared to wired charging.
The result verified the information of the Wireless Power Consortium, the Pixel 4 with wireless charging used 21.01Wh to complete its charging process, with cable the consumption was 14.26 Wh.
This means that with wireless charging, 47% more energy was consumed.
The problem is that if we consider that there are more and more phones that support wireless charging, and more and more users opt for this type of chargers, this translates into greater pollution from energy use, this without considering that the charging process Wireless generates more heat in the phone, and therefore can cause battery problems faster than wired charging.
If you are going to bet on a wireless charging system, it is always best to use original or certified chargers to avoid problems with your phone in the short term.
