| SIM <strong>SIM</strong> (Subscriber Identity Module) is a small card that contains mobile network subscriber's account information. This allows the phone using the card to attach to a mobile network. The SIM card is most commonly associated with GSM and UMTS mobile networks. Moving a SIM card from one phone to another allows a subscriber to switch mobile phones without having to contact their mobile network carrier. SIM cards can also be used by a phone to store limited amounts of data, such as phone numbers and text messages. |

Platform
| 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, One UI 2.0 |
| Chipset <strong>Chipset</strong> is a group of integrated circuits designed to perform one or a more dedicated functions, often with real time computing constraints, Popular smartphones are equipped with more advanced embedded chipsets that can do many different tasks depending on their programming. | Mediatek MT6765 Helio P35 (12nm) |
| CPU <strong>CPU</strong> (Central Processing Unit) mostly known as processors, CPU processes instructions in order to carry out certain functions that make your device operate properly. Processors are often described as the brain of computers, smartphones and tablets, Smartphones and tablets rely on processors to carry out their every task, Processors are an incredibly important factor in selecting any type of computing device, including your smartphone. | Octa-core (4x2.35 GHz Cortex-A53 & 4x1.8 GHz Cortex-A53) |
| GPU <strong>GPU</strong> (Graphics Processing Unit) is a single-chip processor designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display, This includes things such as lighting effects, object transformations, and 3D motion. | PowerVR GE8320 |

Battery
| Battery Type <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. | 4000 mAh |
| Removable | No |
| Charging |
15W wired |
| 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. | No |
