Have you ever wondered if using your phone while it’s charging is safe? You’re not alone. With increasingly powerful devices and fast charging capabilities, it’s become common to keep our phones on while they’re plugged in. But is this habit putting your device at risk of damage or even – horror of horrors – explosion? Let’s dive into the world of electrical engineering and battery chemistry to find out.
The Basics of Phone Charging
To understand the risks involved, it’s essential to know how phone charging works. When you plug your phone into a power source, the charger supplies electrical energy to the battery. This energy is converted into chemical energy, which is stored in the battery. The process involves a series of complex reactions between the battery’s electrodes, electrolyte, and other components.
The charging process can be broadly divided into two stages:
Stage 1: Constant Current Charging
In the initial stage, the charger supplies a constant current to the battery. This stage is also known as the bulk charge phase. During this period, the battery absorbs as much energy as possible to quickly fill its capacity.
Stage 2: Constant Voltage Charging
Once the battery reaches a certain level of charge (usually around 80%), the charger switches to a constant voltage mode. In this stage, the charging rate slows down to prevent overcharging, which can cause damage to the battery.
