Battery Anxiety? Are You Charging Your Phone Correctly?

Many people nowadays suffer from "battery anxiety." Not only that, but many people are unsure about how to properly charge their phones and prolong their battery life. Today, we'll delve into the scientific principles behind phone charging and effective ways to extend battery life.

Most phones on the market use lithium-ion batteries. The charging process involves lithium ions moving from the battery's positive electrode to the negative electrode, while the discharge process is the reverse. To extend their lifespan, the first step is to avoid overcharging and over-discharging.

The charging and discharging process of lithium-ion batteries involves the movement of lithium ions between the positive and negative electrodes, which directly affects the battery's capacity. The amount of lithium ions that can be accommodated by the positive and negative electrodes significantly impacts the battery's capacity. If the number of lithium ions is excessive or insufficient during charging or discharging, it can damage the structure of the positive and negative electrodes, reducing the battery's capacity and ultimately affecting its lifespan.

Therefore, the ideal charging method is to perform shallow charging and shallow discharging. Avoid charging the phone when the battery level is extremely low (around 20%), and unplug it once it's fully charged. This means that when the phone's battery level reaches about 20%, charge it promptly and unplug it as soon as it's full, instead of waiting until the battery is completely drained. This charging method effectively prevents over-discharging and overcharging, extending the battery's lifespan.

When the phone is not in use for a long period, maintaining its battery level at around 50% can also help prolong battery life. This is because lithium-ion batteries are prone to over-discharging when left in a low-power state for extended periods, leading to a decline in battery capacity. Maintaining a 50% charge level effectively avoids this situation.

Besides charging methods, ambient temperature also affects battery life. Avoid charging your phone under conditions below 0C or above 35C, as extreme temperatures can negatively impact battery life. In high or low-temperature environments, the chemical reaction rate of lithium-ion batteries changes, accelerating battery aging and reducing battery capacity.

Lastly, avoid disassembling the battery yourself while using your phone. If you notice any abnormalities such as battery swelling, stop using it immediately and contact the manufacturer for replacement. Leave professional tasks to professionals to prevent accidents.

In summary, the key to extending your phone's battery life lies in avoiding overcharging and over-discharging, maintaining a suitable charging temperature, and performing regular cleaning and maintenance. By mastering these techniques, say goodbye to "battery anxiety" and enjoy a longer-lasting phone experience.
