Now it is somehow not fashionable to compete in the number of camera megapixels. It is also difficult at the current stage of technology, and much more. The race of numbers gradually stopped in this direction but began in another. Now manufacturers are trying to charge the batteries of their devices as quickly as possible, coming up with more and more technical tricks. As a result, if 3-4 years ago very few people knew at all how many watts are in its charging – it charges and okay – now everyone is interested in this indicator and gets upset if a more powerful power supply is not included in the kit. All this is good, but there is still room to strive for, and now Xiaomi is offering a new solution that will allow charging without a wire faster than with a wire. Is this possible?
Xiaomi Fast Charging
Xiaomi, like other Chinese smartphone manufacturers, has decided to step up efforts on wireless charging. The company has announced a new 80W solution that promises to charge a 4,000mAh battery in just 19 minutes.
This figure in itself already commands huge respect, but the intermediate values that they often like to brag about are also very impressive. Xiaomi claims you can get up to 50% in just 8 minutes and 10% in just one minute. 10 percent is enough for the smartphone to work for 2-3 hours, or you can just put it on before leaving the house for a couple of minutes and you will have enough charge for half a day.
I’m not even talking about 50%. If you do not play and disable unnecessary applications, then this will be enough for a day. Let me remind you that we are talking about wireless charging. This is faster than a huge number of wired analogs on the market, and even promising ones, as they say in military aviation.
The previous Xiaomi record for fast wireless charging was 50W. It is presented on the Xiaomi Mi 10 Ultra smartphone. The test results of this smartphone showed very cool results. Even though it has a 4500mAh battery, it is capable of fully recharging it in just 40 minutes. Again, how many smartphones, even with so-called fast charging, can charge this fast over the wire so quickly. Of course, they are, but they are few.
When the Smartphone Charges Faster
When the new wireless charging arrives, it will be another breakthrough and Xiaomi can become the industry leader. But even this is not interesting, but the fact that other manufacturers will get a good kick and will be forced to do the same. As a result, we can say that higher speeds are not far off.
A well-known analyst recently reported that smartphones with 100W wireless charging could appear as early as 2021. Given that Xiaomi has already hit the 80W mark, the goal of 100W wireless charging does not seem impossible. True, Xiaomi has not announced any timeline for when we can see the new wireless charging technology in action, but it will most likely showcase it on the next Mi flagships. They will be smartphones of the Mi 11 series early next year.
Meanwhile, when using such solutions for high-speed charging, the question of battery degradation still remains. Agree, I would not want to charge so quickly and then change the smartphone in a few months.
Is Fast Charging Safe
There are no results of testing technologies from journalists and bloggers since the technologies have not yet fully left the laboratories. But some information is still there now. For example, Oppo, one of the other big players using fast wired charging, admitted that when testing 125W charging technology, battery life drops to 80% after 800 charge-discharge cycles.
It may not seem like much, but it is not. In fact, such an indicator does not look harmless and something needs to be done about it. 80% is not when the smartphone worked for two days but began to work for one and a half. This is serious wear and tear and increases the risk of swelling and even fire.
Nobody wants to change the battery so often, and the manufacturer does not want to be responsible for the possible consequences. Therefore, we still need to work in this direction. Even from an environmental point of view, imagine how the world will be littered with twice as many spent batteries. Especially considering that there are already too many of them, and the issues of processing are very acute.
Seeing the development path of the batteries over the past 10-20 years, we can only wait patiently for the future, which will come very soon. This is really the future because sooner or later we will abandon the wired charging method. It just won’t be faster.
