Earlier charging smartphones was no end of trouble. Indeed, they are extremely power hungry. That's why it was really a problem to constantly look for an electrical point or USB port when the power wears out in the wrong place at the wrong time.
But now the situation has changed. Microsoft gave a lending hand and designed ceiling lamps that allow our phones to automatically recharge. The AutoCharge system employs light beams reflected from ceiling lamps. It doesn't mean that you should locate you phone in a certain place. The system is far more sophisticated. There are cameras to trace where your device is, direct the beams and, voila, your smartphone is getting recharged. The process will take 2-3 hours to refresh your gadget. Keep in mind that the phone should be placed in the same room as the lamps.
Sure, that sounds incredibly nice but it can't replace traditional ways to recharge your smartphone since these lamps are restricted to the home system. Besides, the developers claim it to be «far away from a real product», but still.
