Battery Types:

• Lithium-ion (Li-ion): Most modern smartphones use lithium-ion batteries due to their high energy density, lightweight design, and relatively low self-discharge rate.
• Lithium Polymer (Li-Po): Another common type, Li-Po batteries are similar to Li-ion but offer more flexibility in shape, making them suitable for thinner and more compact devices.

Capacity (mAh):

• Battery capacity is measured in milliampere-hours (mAh). A higher mAh rating generally indicates a larger capacity and, potentially, longer battery life. However, other factors also influence battery life, such as device efficiency and usage patterns.

Voltage:

• Mobile phone batteries typically operate at a voltage of 3.7V to 4.4V. The voltage is crucial for powering the various components of the phone.

Charging:

• Mobile phone batteries are rechargeable. Charging is done through the charging port using a charger or other power sources like power banks or wireless chargers.

Cycles:

• Batteries have a limited number of charge-discharge cycles before their capacity starts to degrade. A cycle is typically counted as a full 0-100% charge.

Battery Management System (BMS):

• Many smartphones have built-in Battery Management Systems to monitor and optimize charging, prevent overcharging, and protect the battery from damage.

Fast Charging:

• Some smartphones support fast charging technologies that allow for quicker replenishment of the battery. However, frequent use of fast charging may contribute to faster battery degradation over time.
