If you also leave your smartphone charging while you sleep at night, be careful immediately. This habit could lead to a serious accident. Learn about the dangers of leaving your phone charging overnight.
Do not charge your phone while sleeping
These days, people use their phones endlessly all day long. They even use them while lying in bed, and when the battery runs low, they leave it on charge before going to sleep. This means they won't have to worry about charging their phone in the morning, and it'll be 100% charged as soon as they wake up. But this habit could one day lead to a major tragedy.
People often think that leaving your phone on charge overnight will only damage the battery. However, there have been numerous cases of smartphones exploding due to overheating and voltage fluctuations. If your phone explodes while you're sleeping, it won't just damage your phone but could even be life-threatening.
Why shouldn't you charge your phone while sleeping?
Many people argue against leaving your phone charging overnight, claiming that new smartphones come with an auto-cutoff feature that stops charging once the battery reaches 100 percent. While this is technically true, it's not entirely true. In reality, when your phone is connected to a charger while apps, Wi-Fi, or notifications are running in the background, the battery will resume charging once it reaches 99 percent.
This process is repeated several times overnight, technically known as trickle charging. This continuous process puts tremendous pressure on the lithium-ion battery, degrading its chemistry. As a result, the phone's battery health rapidly declines within a few months. The phone begins to overheat and sometimes complains of a swollen battery.
When does the blast happen?
A dead phone battery is still manageable, but what if it's a casualty on your bed? Most people leave their phones charging at night and place them under their mattress, blankets, or pillows. Every phone emits some heat while charging, but it's worse when the phone is covered with clothing or a mattress.
This prevents the heat from escaping, causing it to overheat. If the electrical voltage suddenly fluctuates at night, it can cause a short circuit inside the battery. Exceeding the battery temperature can lead to thermal runaway, which can cause the phone to explode and a bed to catch fire instantly.
Adopt these habits
If you want your expensive phone to last longer and protect yourself from any untoward incidents, don't leave it charging while you sleep. Either charge your phone before bed or put it on charge when you wake up in the morning.
Today, almost all companies offer fast chargers that charge your phone in just 30 to 45 minutes. To maintain battery health, charge your phone only when it's below 20 percent and remove it from the charger once it reaches 80 to 90 percent. Never leave the cover on while charging; always remove it before charging.
