Apple currently is lacking behind when it comes to powering device. Many other high end phones in the market comes in with wireless charging and iPhones lacks that.
Apple is supposed to be working on a solution that is a step ahead then the wireless charging. Company is developing technology that would allow iPhone and iPad owners to charge their device without needing to plug it into the wall or place it on a charging mat.
According to Bloomberg speculation that the “cutting-edge” charging could appear in Apple devices released next year, so that would rule it out of making its way into the upcoming iPhone 7, which is expected to arrive later this year on cue with Apple’s usual launch schedule.
Currently you need charging phones don’t require a direct power connection but must be in contact with a mat or charger.
