The S5 comes with a LED light just by the top left of the bezel, which can be set to notify you with a blue light when calls and texts are received when the device isn't being used and the screen is turned off. It also notifies users with a red light when the phone is charging, and a blinking red light when the battery is low.
The proliferation of portable wireless communication devices such as mobile phones, tablet, and laptop computers in recent decades is currently driving the development of mid-range wireless powering and charging technology to eliminate the need for these devices to be tethered to wall plugs during charging.

Qi (/ tʃ iː / CHEE) is an open standard for inductive charging developed by the Wireless Power Consortium.It allows compatible devices, such as smartphones, to receive power when placed on a Qi charger, which can be effective over distances up to 4 cm (1.6 in). [1]
The Hicober 3-in-1 wireless charging station can charge up to three devices at once, and is a great solution for bedside cable clutter. This wireless charger gets rid of cable clutter Skip to main ...
Charging docks supply power, and do not include a host device or data pins, allowing any capable USB device to charge or operate from a standard USB cable. Charging cables provide power connections but not data. In a charge-only cable, the data wires are shorted at the device end; otherwise, the device may reject the charger as unsuitable.
The charge on the capacitor discharges rapidly through the bulb in a momentary pulse of current (c). When the voltage drops to the extinction voltage V e of the bulb (d), the bulb turns off and the current through it drops to a low level (a). The current through the resistor begins charging the capacitor up again, and the cycle repeats.
SpotPass was a Nintendo 3DS and Wii U "always on" online background connectivity system, similarly to how predecessor WiiConnect24 originally functioned with Wii, which could automatically seek and connect to wireless network nodes such as Wi-Fi hotspots, sending and downloading information in the background while in sleep mode or while playing a game or running an application.
An adapter reserving the charging port can retrofit the plug. Battery-powered, wireless Bluetooth headphones are an alternative. Those tend to be costlier however due to their need for internal hardware such as a Bluetooth transceiver and a battery with a charging controller, and a Bluetooth coupling is required ahead of each operation.
