Galaxy S4 will feature Qi wireless charging, back plate and charger to be sold separately



Original article by 

The Galaxy S4 is the most anticipated Android device of the year, and, as spring approaches more and more rumors and reports are emerging about Samsung’s new superphone. The latest such report concerns the presence of a wireless charging module on the Galaxy S4.

According to the Korean news portal DDaily, the Samsung Galaxy S4 will feature a wireless charging module, one that will be compatible with the Qi standard developed by the Wireless Power Consortium. The Korean report claims that Samsung has considered using a different technology to transmit power wirelessly, one based on resonant magnetic coupling.

Resonant magnetic charging differs from electromagnetic induction (the technology used by the Qi standard) by allowing charging at distances of 1-2 meters. In contrast, Qi only allows wireless charging at a distance of up to 4cm (1.6 inch). Samsung has reportedly developed a wireless charger based on magnetic resonance, but the company found that it’s not feasible to commercialize the system.

The coil that enables wireless charging will be placed in the back plate of the Galaxy S4. According to the report, the Galaxy S4 will not come with wireless charging by default. Samsung will sell the back plates fitted with wireless charging coils and the chargers separately, at a price that will be determined.

The Galaxy S3 was supposed to come with a wireless charger accessory, but Samsung never made good on the promise. Another high-profile device to feature wireless charging is the Google Nexus 4, but the orb-shaped charger for the device has not been made available yet.


  1. Funny how a website built on Knowledge of a Technology has little Knowledge on what it reports on. The S4 will look exactly like the S3 does inside the Battery Compartment. Claiming that the S4 will be Qi equipped and then say the Charger Back and Pad will be sold separate is showing that this report is clueless on what it is talking about. The way (wireless standard) it will be charged (Qi or Upcoming Better Way of Charging) is determined by the Back Cover which houses the Receiver Wireless Technology, not internal in the phone itself. The same choices you have to charge the S3 will be the same choices you will have with the S4. Right now you can get aftermarket Back Covers that are Qi and charge on any Qi pad. Of course Samsung will do a Smart business move and offer Qi charging accessories and push their own Wireless charging technology.
    It’s a Shane how the consumer is misinformed by all this incorrect facts and reports on this Technology.
    Facts: Galaxy S3 can charge Wireless with a Back Cover with the Wireless Receiver built in it….Samsung still hasn’t delivered a OEM version
    Galaxy S4 will be the exact way.

  2. Anyone that reads this. Compare their facts here to their facts on the other Samsung S4 reports and and go to the Source of their stories here and Translate from Korean to English and see How this is not Facts from Samsung or the Korean Report and that Qi is not even mentioned.
    We are suppose to take Pride in Freedom of Speech here in the US, that doesn’t mean you have a Right to be Dishonest and make up or twist a report to your likings just to get readers… SHAME
