Is it dangerous to leave the Phone charging all night?

Of the many elements that make up a device, the battery is undoubtedly one of those that generates the most doubts and myths

Night dawns and the first thing you do, as soon as you go to bed, is to make sure that the mobile phone is charging correctly. Otherwise, there is a high probability that the next day the battery will be drained in a very short time.

And who knows if he will do it during a work meeting, just before receiving an important call or, simply, in the middle of a super interesting conversation in a chat room of WhatsApp. Therefore, to avoid the occasional scare, this gesture has become routine.

This question is one of the most common. The answer is very simple: no, it is not bad to charge it overnight. Or in other words, it is not a bad thing to have it plugged in for long periods of time, regardless of the time of day.

Today’s batteries are smart and when they have just finished charging, they don’t keep overcharging. However, it is advisable, if possible, to recharge it only and exclusively when necessary.

So where does this belief come from? In the past, these elements were made of nickel and suffered from the so-called memory effect: if they were repeatedly recharged without depleting all their energy, they lost capabilities and functionality, damaging their lifespan. A problem that was solved with lithium-ion polymer batteries.

How to take care of your mobile battery

  • Charge the phone without using it. Heat is excessively bad for the battery. If we charge the phone while using it, we are forcing the device to use close to 100%, which generates a lot of internal heat that damages the battery. In this sense, it must be remembered that phones do not have active ventilation elements such as fan or liquid cooling, in the case of computers, so if we add to this internal heat the protection cover, the heat it can hardly be dissipated.
  • Use certified and trusted chargers. A charger or cable that does not meet the requirements of the brand of the device can over-power the battery and eventually deteriorate it before the bill.
  • Close background apps or disable features if they are not used frequently. Background applications or applications that remain open after use and do not close automatically, such as social networks or games, increase battery consumption. Therefore, we must get used to closing them after use. It is also advisable to disable functions such as GPS or bluetooth connection.
  • Keep the device charge between 20% and 80% of the total. Currently, and with the exception of older batteries, it is proven that maintaining the battery charge between 20% and 80% of the total, improves and lengthens the life of our batteries.
  • Screen brightness. If we want to enjoy one or two more hours of battery life, we can set the screen brightness to automatic. Also, dark themes have been shown to consume much less battery power than standard ones with bright white colors.
  • Reduce your email update. Finally, one of the most battery-consuming functions is to program the phone to continually search for emails in mailboxes, as it forces mobile data connections. Therefore, it is advisable to configure our email so that the update frequency is every 15, 30 or 60 minutes, or manually, that is, when we enter the application it is updated.
