In recent years, fast charging has become one of the most important functions to minimize charging time on mobiles. Basically, this technology works thanks to an increase in voltage and amperage , which allows charging a phone at a higher speed than usual. With any normal charger, it takes between 1 and 2 hours to charge it, and with this function we can, in some cases, fully charge it in less than half an hour.
The operation is very simple; just get a fast charging adapter and we can already benefit from this technology. However, we must be very careful when choosing one, since the battery of our device can deteriorate at a higher speed and we can even break the phone. If you want to know if your device supports fast charging, you can find it in Settings, in the battery specifications. You can also look at it on the charger and compare to see if you can plug it in or not.

Are fast uploads different?
Despite the fact that each manufacturer calls its adapter differently, the operation is basically the same in all. The only thing that varies are the times and the voltage of each one, although that depends on each brand. In addition, it must be borne in mind that fast charging does not follow a linear pattern, because normally when we spend 60 or 70% of the device’s battery charge, its speed begins to decrease.
How to measure the charging speed, the famous W
To properly understand how the load of any device works, we have to talk about three concepts: watts , volts and amps . Watts (expressed in W ) measure the power or energy released that a given circuit can provide in a given time. Amps ( A ) measure the intensity of current in a circuit. Lastly, volts ( V ) measure the voltage of the circuit. To measure watts, we must perform a very simple operation: amps multiplied by volts . That is, if we look at the specifications of the 5V and 2.4A charger, it will have 12W, a figure that we could already include within the fast charge.
Fast loading of each brand
One Plus: Warp Charge
In its beginnings, Warp Charge was able to support a fast charge of 30W for longer, allowing in less than half an hour to charge a phone to 70%. Recharge your phone from zero to 70% in just 30 minutes. However, the Chinese company decided to go further by introducing the Warp Charge 65 , which arrived last year accompanied by the OnePlus 8T. This new model allows the phone to be fully charged in less than 40 minutes. And there is more, since a few months ago they modified the battery sensors of the OnePlus 9 Pro to fully charge it in 29 minutes, ten minutes less than the 8T.
OPPO: Flash Charge
Yes, you read that right. OPPO holds the record to date for the adapter with the highest number of Watts: 125 . According to the manufacturer’s figures, the Super Flash Charge is capable of charging a 4,000mAh battery in half in 5, yes, 5 minutes. For the moments when you are not in such a hurry and want to take your device to 100% charge, you will have it ready in just 20 minutes. a, in v, and can return 100% charge to the battery in less than 20 minutes, in some cases in 13. In addition, they have others with less capacity, such as a 65W wireless and another in a mini size that reaches up to 110W .
Xiaomi: Super Charge Turbo
Xiaomi‘s fast charging has nothing to envy that of OPPO. In fact, when it was launched in 2019, he dared to compare it with other brands to show that they had created the best on the market. The Super Charge Turbo , which reaches up to 100W , is capable of fully charging a 4,000 mAh battery in just 17 minutes, thus beating all competitors. In addition, the company led by Lei Jun announced last year the world’s fastest wireless charger, the Mi Wireless Charging Technology , capable of charging 10% of a 4,000 mAh battery in one minute, 50% in eight minutes and 100% in 19 minutes.
Huawei has SuperCharge , a 40W fast charging system with which in less than 30 minutes we will get 58% on our device. Unlike other brands, the brand uses a smart charger, and it also has a wireless version with the same capacity. If we compare it with the previous ones, it seems that Huawei’s is much lower, but the charging time is quite decent considering the amount of Watts it supports. On the other hand, the Mate 40 Pro incorporated a 66W charger.
Samsung: SuperFast Charging
Samsung has not wanted to go further in these devices. Its SuperFast Charging , previously called Adaptive Fast Charging, sets its record at 4 5W , which came out with the launch of the 20 Series. However, it is still quite a long way from the Chinese manufacturers, but it is not something they are too concerned about. What’s more, with the new Series 21 that came out this year, they decided to lower it to 25W to avoid problems like the one they had with the Galaxy Note 7. The interesting thing about the adapter is that it also works with models that do not support super-fast charging, so these will charge at the standard speed. Its version without cables reaches 15W .
Motorola uses its own fast charging system, based on Qualcomm’s Quick Charge 2.0 technology (although currently we can find them with QC 5.0) This adapter monitors the status of the battery and adjusts the amount of energy as the charging process progresses, in addition to also manage the temperature at all times so as not to deteriorate it. The brand guarantees that you can get up to eight hours of charging in less than 20 minutes, thanks to its 27W adapter, although we can also get the 18W one .
Last summer, the Realme brand launched its own fast charge, UltraDART . Its technology reaches up to 125W , equaling the OPPO record. This system allows 33% of a 4,000 mAh battery to be charged in just three minutes, figures very similar to the other Chinese company. But it does not stop there, since according to the company’s accounts, a full charge would be completed in just 13 minutes. Finally, the oriental firm affirms that there is no need to worry about the device that we want to charge, since its temperature will not exceed 40º while it is connected.
Fast loads by processor type
MediaTek Pump Express 4.0
MediaTek opted for Pump Express , whose main objective was to prevent the devices from heating up. This fast-charging device is compatible with all phones that contain its processors, from Samsung or Huawei smartphones, through Sony or OPPO, among others. It is currently in its fourth version, and is capable of recharging a battery twice as fast as a standard charger: up to 75% of a 4,000 mAh battery in less than 30 minutes.
Qualcomm Quick Charge
Qualcomm joined the bet on fast charging systems and launched its Quick Charge . Its latest version, 5.0 , offers more than 100W and charges a 4,000 mAh battery from 0 to 100% in 15 minutes. In addition, it improves considerably on its previous versions, both in time and in temperature. As the main novelty compared to the others, the American company affirms that we do not have to leave the mobile at rest for it to work at full capacity.
