On the Internet you can find a multitude of web pages where they address and solve this question clearly: NO, it is not bad to leave the mobile charging all night. However, the myth about batteries still persists because many users are reluctant to accept that these components are not ruined from one day to the next.
That this issue is still in vogue shows that the users’ concern over the battery life of the mobile phone is totally real. And not for less, they are a fundamental part of any device and its capacity seems to take a decade of delay compared to other cutting-edge technology. But it is not that they have not evolved; FullHD panels, GB of RAM, next-generation processors … consume more power than ever before.
Why do we fear the “memory effect”? Nickel-cadmium batteries are quite common in domestic and industrial use, but less and less because of the memory effect and potential contamination. Of all types of batteries, lithium-ion batteries and lithium-polymer batteries, which are used in mobile devices, are those with a lower coefficient of memory effect. In fact, until a study was published in the journal Nature, it was believed that, directly, they did not have this weak point.
It is fair to mention that the memory effect of lithium-ion batteries is practically imperceptible to the user. The very life of smartphones is less than the time that would lead us to notice the natural degradation of the battery. However, there are more factors to take into account when answering the question at hand.
It is true that smart smartphones integrate a system that interrupts the entry of electricity once it is detected that the battery is complete. This, for practical purposes, is equivalent to that we are imminent to disconnect the cable just when the battery level reaches 100%.
The battery is completely discharged, instead, it is a reason to worry. It is hard to imagine that a smartphone off, unplugged and with a dead battery can explode, nevertheless, it is so. The batteries incorporate a system that totally disables them – and forever – when the level of load is very low. This prevents them from becoming unstable and causing critical failures. If this system does not exist, empty batteries may explode or catch fire.
In this regard, Andrew Goldberg, technical editor of iFix, says: “Something that is not a problem is the” overload “of the batteries. Unlike what you may think, leaving your mobile or your laptop connected all the time is not bad for the battery. That’s because of your devices, their batteries and their chargers, are actually quite intelligent. The charge that continues to get the battery once it has charged its maximum capacity actually does much less damage than what it suffers when it is completely discharged.”
There are many factors that come into play when assessing battery life and keeping it plugged into the power all night is not the most relevant. For example, charging the phone with a holster can cause some heating of the smartphone and increase the temperature of the device. The heat itself is a risk factor to take into account.
“Lithium batteries can react badly if the phone is exposed to high temperatures,” says Shane Broesky, co-founder of Farbe Technik. “If you have a holster on the device that does not allow the heat to dissipate, this heat will increase the battery temperature and cause the cells to rust, which will reduce capacity and service life.”
Now, there are reasons beyond the batteries themselves to avoid having to plug the mobile all night. Any device connected to the electric current can suffer from a simple fault or overload in the transformer. It is advisable to avoid having to carry the smartphone for many hours in a row as a matter of precaution, but lithium-ion batteries could withstand it with little degradation.
On the other hand, experts recommend keeping the battery charge between 40% and 80% of its total capacity. “This allows charged ions to continue working and protect battery life,” says Broesky. “It Loads the device in short periods throughout the day will give these ions enough energy to keep them going.”
The good news is that leaving the mobile charged all night does not negatively affect the autonomy of our smartphone. Chances are that other mobile components deteriorate or become obsolete long before the battery fails to properly perform.
