Smartphone Charging Tips: Nowadays, most people sleep comfortably by charging their phone before sleeping at night so that they get 100% battery as soon as they wake up in the morning. But do you know that this habit can prove dangerous for both the battery and security of your smartphone? If you also do this, then this small carelessness can reduce the lifespan of your phone and sometimes can even become the cause of a fatal accident. Let us know why leaving the phone charging overnight is harmful.
Continuous charging puts pressure on the battery
The battery of every smartphone is made on lithium-ion or lithium-polymer technology. When the phone is 100% charged and still remains plugged in, overcharging stress is created inside the battery. This reduces its charge cycle life, that is, the battery starts weakening sooner than before. With time the battery holds less charge and the phone starts discharging quickly.
There can be danger from excessive heat
Leaving the phone on charge all night increases heat generation. For a long time, this heat can damage not only the battery but also the internal circuits of the entire phone. In many cases, overheating of the phone can also cause incidents like fire or blast, especially if you use a cheap or local charger.
Power fluctuations can cause huge losses
If the electrical voltage suddenly increases or decreases during the night, it may damage the phone’s charging port, battery, or motherboard. Because you cannot maintain vigilance while sleeping, this risk increases even more.
What is the correct method of charging?
There is no need to charge the phone to 100% again and again. According to experts, it is considered best to keep the mobile charged between 20% to 80%. This does not put much pressure on the battery and increases its life. If you have to charge at night, then use a phone or charger with smart charging feature that automatically stops charging when the battery reaches 100%.
Keep these precautions in mind
- Always use original charger and cable only.
- Never keep the phone charging under the pillow or under the blanket.
- If the phone is overheating, stop charging immediately.
- Leave the habit of leaving your phone charging overnight and charge it during the day.
