For some time now, it is common to find a text like the one that follows when we talk about a new device: 'the (device name) has 3,200 mAh battery, although if this seems little to you we can use the fast charge that comes by default '. And it is true: given the shortage, in certain terminals, of their own autonomy, it is good to know that we can connect it to the network for fifteen or twenty minutes and inject enough energy to reach the end of the day without getting hung up. Once fast charging arrived in our lives, the controversy did not take long to arise: was this a healthy technology for our mobile? Could we always use it and our battery would not suffer any damage, without counting, of course, the wear and tear of its utilization?
Quickly, society was divided into two: those who affirmed that yes, that fast charging should, by necessity, wear out the terminal and those who affirmed that it is another urban legend, that using fast charging did not affect at all and that It belonged to the field of other similar hoaxes such as those who claim that the terminal cannot be used while charging or that it is harmful for it to leave it connected to the electricity grid all night. Now, a study that has just been published seems to agree with the former: using fast charging decreases the useful life of our phone's battery.
Fast charging, yes or no? Apparently we already have an answer
This seems to have been shown by a new study by Purdue University in the United States. The study, led by assistant professor of mechanical engineering Keije Zhao, has apparently shown that fast charging degrades the components of the lithium batteries of our mobiles and other devices such as computers and cars. The study proves that fast charging causes irreversible damage to the battery's electrodes, polarizing it and causing it to lose its charging capacity as it is used. This is how Zhao himself explains it:
To demonstrate this, the researchers participating in the study built a three-dimensional model of the device, subsequently analyzing all the changes produced in the battery in the states of charge and discharge. They also used an artificial intelligence X-ray machine to scan hundreds of electrode particles from a lithium battery, using machine learning algorithms. The researchers were thus able to locate areas of the battery that were damaged using fast-charging technology.
The researchers, in addition to concluding that fast charging decreases the useful life of batteries, assure that an effective solution has not yet been found to prevent this from happening. Some brands, such as Samsung, enable among their functions the possibility that the user can use, or not, fast charging. From here we advise all users who have a mobile with fast charge to use it only in cases of need, using in other cases a charger of the brand with less power.
