1. Understanding the iPhone Battery
– The iPhone battery is a type of Li-ion battery with the main component being an electrolyte that acts as a medium for Li+ ions to move back and forth between two electrodes. – When the device is operating, Li+ ions move from the anode to the cathode, and the process reverses during charging. – The lifespan of a Li-ion battery is calculated based on charging cycles. – Battery degradation is due to a certain amount of Li+ ions being retained at the two electrodes after each charge/discharge cycle due to the chemical processes occurring in the battery.
