The battery, or rather the autonomy of mobile phones, has always been key. Smartphones have less autonomy than traditional mobile phones, and that will probably be the case forever. Improvements are coming, and a very recent one has been fast charging. The question is, what is more relevant, a large capacity battery and, therefore, more autonomy, or fast charging?
More autonomy
Obviously, the ultimate goal is to ensure that mobiles have more autonomy. That is to say, that the mobiles work longer without having to charge them. For this, there are different ways of improvement. One of them is to get batteries with more capacity, and the other is to get the mobile to consume a lower amount of energy, or to use energy better. Two options that manufacturers are working on that also pose problems. A battery with more capacity also takes up more space, the mobile will be larger and weigh more. Batteries with more condensed energy could also be achieved. That is, in the same space have more mAh. But lately fast charging has become the great option.
Quick charge
And it is that perhaps it was not counted as a possible option until relatively recently. Fast charging allows us to charge the mobile battery in a short time. We are not talking about having to spend several hours charging the mobile battery to have the battery at 100%. Sometimes charging it for just 10 minutes could be enough to have the autonomy we need. And many times, we have electrical outlets nearby that we can use throughout the day for 10 or 15 minutes, without modifying our routine. That is important. Why? Because it is no longer so relevant how long the mobile battery lasts, but simply that the battery charges fast enough to charge in the time in which we can plug in the mobile. Rare is that we can not charge the mobile once through an external battery, or with a plug at work or in a cafeteria. Maybe getting better at fast charging is the key. What if charging the mobile to 100% only took 15 minutes? It could solve the great problem of current mobiles, which is their autonomy of energy.
