The intensive use of mobile phones requires charging their batteries (at least) once a day, which is why more and more users are turning to fast charging. This technology allows a full charge in just over 20 minutes (five minutes for 30% capacity), compared to the almost two hours that a normal charger requires.
If it’s about getting the phone to charge as soon as possible, why don’t all mobiles use it? One of the main reasons is that, as has happened in the past with VHS and Beta (or even the different cables to charge mobiles), there is no unified technology. However, the most widespread is Qualcomm Quick Charge, since the American manufacturer includes it in its Snapdragon chips.
Thus, one cannot speak of fast charging but rather of various technologies that achieve the same thing by increasing the voltage, the amperage, or both, so that the power to recharge the battery ‘comes in’ much faster. While ordinary chargers and phones charge batteries with a voltage of 5V and an intensity of between 1 and 2 amps, those of fast charge have a range of between 5 and 12V and between 2 and 4 amps. By connecting a fast charger to a device prepared for this technology, the two synchronize and establish the flow of energy for an optimal charge. This power will be higher the emptier the battery of the phone is, so they recharge much faster at first, and then the rate is slightly reduced.
The second reason why fast charging is not used by default is also relevant: keep in mind that the faster the phone charges, the more the battery degrades. This is so because the chemical reactions that take place inside it take place more quickly and at a higher temperature. Consequently, it is advisable to use fast charging only when strictly necessary.
Charging a mobile phone faster is not as simple as using a more powerful charger. Since if the phone receives more energy than it can handle or does not ‘sync’. There is a possibility that it will break down. Luckily, today’s gadgets can limit the power that reaches them from the charger if it is excessive.
How to know if your mobile is compatible with fast charging
To be able to use a fast charger on the mobile, the first and basic thing is to know if the phone is compatible with this technology. In the case of iPhones, it is very easy to know which ones: all models equivalent to or later than iPhone 8 and iPhone 8 Plus. What is needed in this case is an Apple USB-C to Lightning cable and an Apple USB-C 18, 29, 30, 61, 87, or 96 W power adapter (indicated on the bottom of the apparatus). We can also use a third-party USB-C power adapter that supports USB-PD (‘Power Delivery’) power supply. In about 30 minutes it will be charged up to 50% of the iPhone battery.
The easiest way to know if an Android phone is compatible is by checking the technical characteristics of the device and if the charger is indicated somewhere that it is fast charging. In some models, it can also be seen by going into ‘Settings’ and then ‘About this phone’, under ‘Battery information ‘. If the smartphone operates at more than 5V and 1 or 1.5 amps. It is very likely that it supports fast charging.
