Mobile manufacturers have invested a lot of effort in improving the charging systems of their terminals. They are one of the most widely used claims when presenting a new phone: that a mobile phone is very fast charging a large battery is something that is valued positively in any analysis.
Having several days of autonomy to be able to forget about the charger that time is a highly demanded quality, but to charge batteries of up to 5,000 mAh you need to have a fast charging system or you will get gray before you see your phone at 100% of Energy. The problem is that these fast systems that brands are using on many models can help degrade the battery prematurely.
Brands like Oppo or Xiaomi compete to achieve the fastest system, with figures that are already around 40, 50 or even 60 W, but Oppo itself would have recognized that this method reduces the useful life of the batteries. According to a tweet from Andrei F., a collaborator with the AnandTech technology specialist, Oppo would have recognized that 40W wireless fast charging degrades battery capacity to 70% in the same number of cycles that a fast charging system needs. 15 W to degrade that battery to 90%.
That is, if what we are looking for is a mobile that can last us for at least four years without the battery problems, the best thing would be to avoid constantly using the phone’s fast charge. It is becoming difficult to find a terminal that does not offer this option, the Oppo catalog itself is one of those that has strongly embraced fast charging, but that does not mean that you have to use it daily.
On the other hand, those consumers who use to change their phones every year or every two years can surely enjoy the fast charging technology without affecting the deterioration of the battery, since by the time this component begins to give problems already they will have changed it for a new one .
But not all brands have made the jump to fast loading. Apple, for example, is one of the brands that is resisting the most: the iPhone 11 Pro Max, for example, has only an 18 W charger. The rest of the manufacturers already regularly exceed 20 W in the fast charge of any terminal that goes on the market.
