Putting the mobile to load when practically exhausted or left plugged in all night are common habits among users. But both have a direct effect In battery degradation. The reason? Lithium ion batteries, which use practically all current smartphones, suffer more the more their ends are more: Nor is 100 % ideal, nor 0 %.
Apple, Samsung and other manufacturers have made it clear on many occasions: it is best to keep the battery in a range between 20 % and 80 % To extend your useful life. Apple, for example, explains in its official battery health guide Loading the 100 % iphone frequently represents wear. For this reason, manufacturers have long offered battery protection options that stop the load when reaching a percentage of the 80 or 85 %as the case. This seeks to maintain its integrity during as long as possible.
The physicist David Mackayformer scientific director of the consultancy Carbon Trust and professor at the University of Cambridge, he already explained in one of his essays that the lithium batteries ‘They are not designed to constantly remain capacitysince that chemically stress the cells’. The Overload generates heat and accelerates processes such as electrolyte oxidationwhich deteriorates performance over time.
On the other hand, Let the mobile go completely also take its toll. According to Battery Universitya reference website in battery research supported by CADEX Electronics‘A deep discharge puts the cell under tension and can damage it permanently’. The general recommendation is load the device when between 20 % and 40 %.
Limiting the maximum load is not the only measure that manufacturers have taken. For those who leave the mobile plugged during the night, the Pixel of Google incorporate an option of Adaptable load who learns from user’s habits to arrive 100 % just before waking up And so prevent it from staying hours to the fullest. Other manufacturers also include similar options.
In conclusion, it is advisable to carry your mobile before it came out of 20 % and that you unplug it without reaching 100 %. If you use functions of Intelligent load either battery protectionbetter. And, above all, avoid exposing it to high temperatures while loading: heat is the worst enemy of your battery.
