Freescale wants wireless charging to be 3x faster

Freescale wants wireless charging to be 3x faster
Wireless charging is pretty awesome. Unfortunately, it is already starting to lag behind because of recent advances with chipsets that have sped up wired charging speeds by a significant amount. Freescale wants to help bring things back closer to parity with new hardware that could allow you to wirelessly charge devices up to 3x faster.

The basic idea behind the speed increase is the same as with newer USB chargers, which can feed a higher voltage to your device, pushing about 14 watts of power instead of the traditional 5 watts. Freescale has developed new hardware that can push 15 watts of power wirelessly. The downside is that right now, it requires new hardware in both your smartphone and charging pad; so, you can't just get this going. And, Freescale's chips aren't Qi standard compliant, though Freescale says that Qi compatibility only requires a "tweak", as would compatibility with lesser-used standards like that of the Power Matters Alliance. 

Of course, it should be noted that the Qi standard does actually support up to 120 watt charging, if the hardware can handle it. Freescale says that it will have chips and reference designs ready for Q1 2015; so, it seems likely that we'll be seeing fast wireless charging hardware sooner rather than later.

Don't know anything about this, but wouldn't pushing 15 watts instead of 5 watts be bad for the longevity of a battery?

Yes, but not for profits.

Think about the EMI leakage and radiation. The higher the wattage, the higher the risk. Nowadays, do companies only think about profit and money, but don't care about the risk to human beings, especially to the infants!

Depends of the SoC and the charging chip, for example, quickcharge 2.0 push @ 12v first, then goes down to 9v and then to 5v.

120 watts wireless charging. Wow, that's a lot.

This is a bad idea, wireless charging produces enough heat as is...

We mostly use the wireless charging for our 2 Moto Turbos and one Nexus 7.2 overnight. Just drop them on the charger and by morning all is 100%. Speed isn't much of a concern. If I need fast during the day, I just plug in the Turbo Charger and add another 40-50% in 30 minutes. Althought, with 3900 mAh on the Turbos, this doesn't happen very often, more often needed on the Nexus 7.2.

But, have you ever thought about the energy wasted? Wireless Charging is inherently much less efficient than Wired Charging. If we really care about global warming, Wireless Charging should be banned. If we really care about how to maximize our hard-earned money, Wireless Charging probably would be out of consideration. However, in order to keep alive the companies who try to make a living by selling the wireless charging technology, consumers should probably continue the charitable act by keep buying wireless chargers :)
