|Operating System <strong>OS => </strong> Every computer system run on a base software called Operating System (OS). Operating System controls all basic operations of the computer (such as smartphone, PDAs, tablet computers and other handheld devices). The Operating System allows the user to install and run third party applications (apps), apps are used to add new functionality to the device.||Android 10, upgradable to Android 11, One UI 3.1|
|Battery <strong>Battery Type => </strong> Cell phones run on various kinds of batteries depending on the manufacturer, phone size or shape and features. There are basically four types of cell phone batteries => Lithium Polymer, Lithium Ion, Nickel Metal Hydride and Nickel Cadmium.||Li-Poly (Lithium Polymer)|
|Capacity <strong>Battery Capacity</strong> is a measure (typically in Amp-hr) of the charge stored by the battery, and is determined by the mass of active material contained in the battery. The battery capacity represents the maximum amount of energy that can be extracted from the battery under certain conditions.||6000 mAh|
|Wireless Charging <strong>Wireless Charging</strong> (Inductive Charging) uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.|
|Bluetooth <strong>Bluetooth</strong> is a wireless communications technology for exchanging data between mobile phones, headsets, computers and other network devices over short distances without wires, Bluetooth technology was primarily designed to support simple wireless networking of personal consumer devices.||Bluetooth v5.0 (LE up to 2 Mbps)|
