Today we see mobile phones on the market with cameras with 200 megapixel sensors, screens of almost 7 inches and refresh rates of 165 Hz, as well as processors with impressive performance. But some of the material that seems to have been left behind on cell phones it’s the battery.
I say “it seems” because in reality, it’s not like that. Even though the battery capacity seems to have peaked at 6000 mAh, with an average between 4000 mAh and 5000 mAh for most cell phones, in this case the size (or rather capacity) does not matter. not all. Current cell phones manage battery consumption much better and, on the other hand, charging is faster than ever.
This last aspect, however, is surrounded by myths: does fast charging harm battery health? The quick answer is: no… even if it’s not that simple.
Fast charging does not ruin your mobile battery, but…
It’s been a long time since cell phones came with 5W or 15W chargers in the box (in fact, many cell phones no longer include a charger in the box, but that’s another topic). For the past few years, we have expected a mobile phone to support at least 20W fast charging. And if it’s faster, the better..
In addition, we have devices with super-fast charging up to 120W, as is the case with the Xiaomi 13T Pro. The Asian company claims this can charge the battery from 0 to 100% in less than 19 minutes, a ridiculously fast (and surprising) speed. And there are even faster ones, like the Realme GT 3 Neo with its 240 W fast charging.
The problem with fast charging lies in the biggest enemy of a battery’s life and health: heat. Excessive heat damages cell phone batteries, which causes them to experience greater wear and tear than normal. This is why it is never advisable to leave your phone directly in the sun for a long time (have you noticed how much hotter than usual it is when you use it on the beach?), and even less if he is in charge.
Knowing that heat is the enemy to fight and that ultra-fast charging can produce more heat, manufacturers have designed cell phones and chargers that better manage temperature, both during charging and during use. This is why cell phones include systems such as vapor chambers to help dissipate excess temperature. But with fast charging, it’s better to take precautions.
Experts recommend using fast charging only in specific cases, such as quickly charging your phone before leaving the house.
Technically, the cell phone and charger are designed to allow this charging speed, but despite this, experts recommend using fast charging. only in really necessary cases. For example: Is your battery very low and you have to leave the house in a few minutes? Are you at a coffee shop and need to charge your phone for a short time before continuing with your day? In such situations, it is advisable to use the fast charger.
What is not recommended is leaving your phone charging overnight using fast charging.. In these cases, it is better to use a slower charger, 15 W or even 5 W. Charging will take much longer, but that’s okay, you will sleep. And of course, it is advisable to activate optimized charging.
According to the manufacturers, mobile phones with these charging capabilities are designed in such a way that even when using fast charging, the battery life remains at least 80% after 800 or more charging cycles. However, it is wise to take their claims with a grain of salt and while fast charging is not harmful, With great power comes great responsibilityso let’s use fast charging wisely.
