1. Why not charge your phone overnight
Charging a phone overnight can cause many unexpected hazards, such as:
battery bottle, reduce battery life
The life of the battery depends not only on the battery composition, charger, charging place, charging temperature, etc., but also on the user's charging habits. Chemically speaking, cell phone lithium-ion batteries gradually "age" over time. Moreover, if the user has the habit of charging the mobile phone all night, it will speed up the charging process of the battery and reduce the battery life.
Apple has issued a warning with iPhones that leaving the iPhone battery charged for a long time after the battery is fully charged will shorten the battery life.
Similarly, Samsung manufacturers also reminded "do not leave the phone connected to the charger for a long time or overnight." That is, you can only charge the phone until the device is fully charged, and you must continue to disconnect the charger.
Typically, a phone stops charging when the battery is 100% full. However, certain apps or software running in the background of the phone can drain the battery and cause the battery percentage to drop. At this point, the phone will start charging the battery again to fully charge the battery. Repeating this process overnight will cause the battery to age and rapidly shorten its life.

potential fire hazard
Why not charge your phone overnight, because charging your phone overnight can build up too much power, posing a risk of fire and explosion. What's more, many people are still charging their mobile phones in places where heat is difficult to dissipate, such as blankets and cushions, causing the mobile phone to heat up during charging, which becomes an unexpected fuse, making you unable to move your hands in time.
In addition, the use of poor-quality, damaged, or broken charging cables may short-circuit when overloaded, causing fires and explosions. Especially when charging your phone overnight, it's hard to control the state of charge.

Impact on Human Health
When most users charge their phones overnight, they do so close to where they sleep. The heat released during the charging process and the amount of electromagnetic wave radiation emitted by the naked eye affect the sleep cycle, causing you to have sleep disorders and gradually endangering your health. Here's why you shouldn't charge your phone overnight.
2. How to Properly Charge Your Phone Overnight
Set up overnight phone charging
Many smartphone lines are now equipped with a battery charge control feature that helps phones charge safely overnight.
For example, in iPhones, starting with iOS 13, the Optimized Battery Charging feature has been added. This feature only charges the battery up to 80%, and then limits how much power can be charged to the device overnight or during extended periods of charging. To use this feature, go to Settings => Select Battery => Select Battery Status => Select Optimize Battery Charging.

For Android phones, it is also equipped with the function of controlling the charging process, which can be safely charged. To use this feature on an Android phone, go to Settings => Select Battery Management => Enable the feature equipped on your device. Alternatively, you can download and install a third-party battery management app, such as AccuBattery, to keep your phone's battery safe overnight.
While phones are equipped with a safe charging feature, experts also advise users not to frequently charge their phones overnight.
Charge your phone in a cool place
If you're charging your phone overnight, don't charge it on top of a blanket, pillow, etc. Instead, it needs to be charged in a cool, shaded area so that the heat generated doesn't heat up the device.
Keep a certain distance from the lying position to charge
As mentioned above, the amount of radiation emitted by mobile phones during charging is very large, which will seriously affect human health. On the other hand, charging overnight can cause the device to overheat, potentially catching fire. Charging your phone away from lying down will help you avoid injury.
