Phones without Charging

A signed to a connected device giving Strong signals in almost any environment

The released patent does not gives detailed idea about the operating frequency and technology which will be going to use. But predictions could be match that frequency.

In simple words there is no any tension of charging mobile phone time to time in future because as we enter in home charging of devices automatically get starts and as we are leaving home we get sufficient charging for all day use without any efforts.
This technology is awesome as it reduces all the efforts of human as it requires for charging the Mobile phone. But cons of this technology is it reduces the battery life. Due to continues charging battery life decreases and we should replace the battery. This will interesting to see how apple will develop this technology .

• Low infection risk – For embedded medical devices, transmission of power via a magnetic field passing through the skin avoids the infection risks associated with wires penetrating the skin.
• Durability – Without the need to constantly plug and unplug the device, there is significantly less wear and tear on the socket of the device and the attaching cable
• Inconvenience - When a mobile device is connected to a cable, it can be moved around (albeit in a limited range) and operated while charging. In most implementations of inductive charging, the mobile device must be left on a pad to charge, and thus can't be moved around or easily operated while charging.
• Induction chargers use an induction coil to create an alternating electromagnetic field from within a charging base, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electric current to charge the battery
• More evidence that Apple might be soon ready to debut wireless charging surfaced this past week with the discovery of new patent filing on technologies related to inductive charging. The filing -- first discovered by Patently Apple -- is primarily on brushing and polishing techniques for cylindrical and contoured metal surfaces, however in describing usage cases, Apple curiously brings up inductive charging.
  Whether or not Apple is going wireless when it comes to charging has been a subject of debate for at least the past five years. Patently Apple first discovered patents for wireless charging back in 2012, but marketing chief Phil Schiller in September of that year downplayed any rumors telling AllThingsD that the company believes it isn't clear how much convenience wireless charging adds.
  Even with Schiller's public comments, Apple watchers didn't quite believe Apple was totally giving up on the idea, and since then additional patent applications have surfaced indicating the company is very much still working on some type of inductive charging system.
  It appears that this new metal brushing/polishing technique is aimed at making the surface of the dock smooth enough to allow a good connection. In fact, a read of the patent itself speaks specifically about tools to create a space for an inductive coil.
  The illustrations in the patent suggest that what Apple's proposing for a possible charging station isn't exactly groundbreaking. You'd likely sit the device on top of the charging puck, and it could potentially be held there by some type of magnet to prevent it slipping off. The device itself would be connected to power via USB.
  As for when (if ever) we'll see the technology in a real iPhone or other iDevice, that's not yet known. Some rumors of the iPhone 7 specs did suggest Apple was considering adding wireless charging, however no wireless charging was announced at launch. It is possible that Apple may be holding off on such a feature for the iPhone 8, which is largely expected to be a significant redesign, including an edge to edge oled display.
