Today in the market there are mobiles capable of charging in less than an hour . Today almost any input range has charging speeds of 18W and at the top of the telephony catalog we can enjoy charging systems of up to 65W. This can make doubts assail you when it comes to charging your new mobile.
If a smartphone can be charged in just over an hour, is it appropriate to leave it charging overnight ? What happens if my mobile spends 8 hours connected to the power? There are many who think that this activity could degrade or overcharge our batteries, but for years these cells have security systems that have evolved to adapt to fast charging systems.
Nowadays, all phone manufacturers integrate batteries with a certain capacity and charging speed into their devices, but to this we must add the control technologies, present both in these components and in the charger, to follow strict performance standards and security.
At this point, the mobile processor is in charge of managing the charge that is taken from the charger, preventing fast charging of the mobile from damaging the battery.
Can a battery be overcharged?
Overcharging used to cause anxiety among phone owners. The fear was that keeping a phone constantly plugged in could charge a battery beyond its capacity, making the battery unstable, which could degrade the overall life of the component or build up too much internal heat and cause the battery to explode or catch fire. .
Today, a battery management system is designed to turn off the electrical load once the battery reaches 100%, before it can become overcharged. “Unless something goes wrong with the battery circuits, you can’t overcharge a modern phone,” says Venkat Srinivasan, a battery researcher at the Argonne National Laboratory and director of the Argonne Collaborative Center for the Science of Energy Storage. “Smartphones have built-in protection to exactly prevent this from happening.”
For this reason, if we look at the last moments of work of a fast charging system, we can see how when it exceeds 90%, the charge is usually slower. When reaching 100%, despite having the mobile connected to the current, the power supply will stop.

On Android, this process is usually automatic, but if you frequently keep your iPhone plugged in during the day or while you sleep, you can turn on an iOS 13 battery setting called Optimized Battery Charging that controls the charging schedule and will hold the charge. iPhone battery to 80%, keeping it out of the stress zone. After that point, the charge will be 100% complete just before regularly disconnecting the phone.
