Fast charging in cellphones is constantly evolving and right now the cap is worth the redundancy on Xiaomi’s roof with its maximum load of 200W. A fast charge powered by the double batteries which begin to impose themselves more and more clearly and which allows charge 4000mAh from 0 to 100 in just 8 minutes.
But these rapid charges carry within them the germ of their own weakness, and this is because they cause a rise in temperature at the time of charging which tends to degrade the batteries themselves. However, Xiaomi wanted to overcome doubts about its new fast charge and said the degradation is far from drastic: We will only lose 20% of battery in two years of use.
Only 20% less on 800 loads at 200W
The useful life of the batteries is reduced, as we have commented, due to the additional temperature provided by fast charges (Among other factors, of course, but this is the most notable). Therefore, it is generally recommended to reduce the speed of this charging if we do not need to use the phone immediately, thus extending the useful life of the internal battery of our mobile phone.
So, the usual thing is that the batteries lose their efficiency when we make full or partial charges of their stored energy, and the battery change becomes one of the most common and necessary maintenance when we are going to have a phone. owned for a long time. time. Now, Xiaomi claims its fast charging is far from aggressive on the battery and that maintains its lifespan almost as if we are not enforcing that charging speed.
As the oriental manufacturer explained in a series of questions and answers carried out on its Weibo account, the 200W fast charge designed by its company is able to maintain 80% of the useful life of an internal battery after 800 cycles. dump. It would mean lose only 20% efficiency in about two years of life of a cell phone, or two years and two months with a daily charge.
Certainly, quite satisfactory figures that will logically have to be tested, but which exceed the minimum required by the authorities in your country. In China, it is specified that the country’s standards require maintaining 60% of the efficiency of a battery after 400 cycles. It is clear that Xiaomi’s charging system appears to be significantly more respectful of battery life than what is required in the country.
To all this, logically, we must add to achieve good battery maintenance this includes running other processes and not everything happening to determine which load speed is the one being used at all times. Charging a phone at night at 5W seems to work in order to maintain the life of an internal battery, and it also looks like the effects of Xiaomi’s 200W fast charging won’t be much more damaging. That’s what Xiaomi says, of course.
