A warning not to leave the mobile phone charging at night.. I know the reason
We all think that the best time to charge the phone is at night, but in reality this may negatively affect the battery life of the device over time and lead to problems in the device.
Recommendations for charging the mobile battery
Huawei’s device makers say, “Don’t leave the phone connected to a charger for extended periods of time or overnight.”
Manufacturers recommend keeping the battery charge between 30% and 70%, which is the best way to extend battery life. Many phones manage to know the remaining percentage of the battery charge through the settings, and Apple provides an improved setting for charging iPhone phones that keeps the charge percentage below 80%.
You should also avoid completely discharging the battery to 0%, as this maintains polarity and increases battery life.
How is the mobile battery charged?
Most smartphones operate with lithium-ion batteries, and these batteries degrade over time regardless of how you charge the phone, because they work by transferring charge carriers between the electrodes, and this process affects the components of the battery and damages its efficiency over time.
Battery charging problem up to 100%
Kevin Purdy of iFixit provided an example to understand the topic, writing for the New York Times. “It is very easy to fill a sponge with water to get it from a dry state to a saturated state, but trying to force an almost saturated sponge to absorb more drops of liquid takes effort, and some excess pooling liquid may remain on the surface of the sponge,” Purdy said. This assembly consists of (SEI solid electrolyte layer) that builds up on the battery, and this buildup reduces the total capacity of the battery.”
Dangers of leaving the mobile charging at night
In addition to harming battery life, charging devices at night can also be a health and safety concern if we do not consider where we place our phone while charging. Charging usually causes the phone to heat up, and if something goes wrong, flammable surfaces in contact with the phone can become rather dangerous.
Paul Shaw, head of fire investigations for the Staffordshire Rescue Team, told the Guardian: “Phones should not be placed under pillows or charged in bed.
The so-called thermal runaway occurs in the battery, and the phone heats up little by little, but this heat is not strong enough to affect hard surfaces or wooden tables.
It should be given more importance, and if you want your device to have a better battery life for a long time, don’t let your phone charge while you sleep.
