Fast charging is a technology which has long been no surprise. Today it has become the norm to put your smartphone on charge and after an hour to 100% charged camera, which is enough for another half a day or two. Someone says that quick charging harms the battery, Theda her life, but common sense suggested that it is completely wrong and that technology can and should be used. In the end, it is much easier than to charge your smartphone 3-4 hours in hopes of an imaginary extension of the battery life. But how important is the power fast charger?
Whether the wireless charging to charge with the speed of wired?
It is considered that the charging rate depends on the wattage of the power supply, of course, provided that the phone supports this power. That is, if you connect to the unit with 20-watt charging 40 – or 60-watt charger, to realize his potential, he can not, and hence charge faster than provided by the manufacturer, too. Therefore, manufacturers strongly compete with each other to see whose smartphone supports a more powerful charge and therefore the faster it is charging.
Quick charge it charges slow
Huawei P40 Pro+, which is already sold in Russia, supports 40-watt memory. It is quite a lot, since most modern devices are compatible only with power 20 watts. Therefore, colleagues from the publication as PhoneArena decided to see how fast a 40-watt charging nourish Huawei P40 Pro+ up to 100%.
The result was that the smartphone battery capacity of 4200 mAh when charging by wire is filled with over 70 minutes. Not bad, but clearly not a record, considering that my Honor View 20 20-watt memory is charged to 100% in just 72 minutes, though its battery has a capacity of 4000 mA*h. That is, it is pozvoyalet to the conclusion that fundamental differences between 20 – and 40-watt power supply no. In any case, in the case of Huawei flagships.
Why charge your smartphone quickly gets?
Another thing is wireless charging. It turns out that Huawei P40 Pro+ supports 40-watt charging standard Qi and use it to charge to 100% only 12 minutes longer than the wire, for 82 minutes. To achieve this the charging rate of the manufacturer is a small trick and complements the wireless charging station, which gives the output 40 watt, 65-watt power supply. Obviously, this is because of energy losses that can not be avoided in the case of using induction.
Fast wireless charging
But since wireless charging is a phenomenon which is used by very few, back to the classic way recharge the battery. If you look at the comparison table above, we can notice that a 40-watt charges your Huawei memory P40 Pro+ 50% in just 30 minutes. It seems to be a bit. But my Honor View 20, which – recall – is equipped with 20-watt power supply, charging to 50% in 24 minutes. What does it mean? And the fact that in this case 40 watts, which offers P40 Pro+ is okolomarsianskuyu trick, not giving real benefits.
And this applies not only smartphones Huawei, but rather a wide range of devices. The same Galaxy Note 10+, which supports a 45-watt charger, charge to 100% and 56 minutes and the Galaxy Note 10 which is only compatible with 25-watt solutions, reaches the same mark after just 8 minutes after his older brother. As for me, the difference is not so big to pay for heavy duty storage, which also still have to buy it separately.
Harmful quick charging
Undeniably, there are smartphones with really fast charging. For example, Xiaomi Mi 10, which, thanks to a 65-watt power supply unit is recharged in 45 minutes, and Oppo Reno Ace, whose charging time is 29 minutes. This is really outstanding results, but keep in mind that to find the real charging rate in advance you will still fail, not to mention the need to purchase a charger separately. And what’s the difference if most of us still leave the smartphone to charge at night?
