0In modern phones, there hasn't been significant leaps in technology lately, and at times, it seems like there's nowhere else to grow until the next fastest charging phone emerges. Yes, fast charging technology is advancing by leaps and bounds, and it's one of the areas that captures close attention.

Current trends in fast charging
Currently, phones consume too much energy due to large screens, powerful processors, Wi-Fi, Bluetooth, GPS, and other services. Meanwhile, the device's body is very thin, meaning the battery capacity is physically limited. Rarely does a battery manage to hold a charge for more than a day with active phone usage. To avoid increasing the size, manufacturers have taken a different path and created fast charging, capable of charging the battery very quickly, with some models doing it in as little as 10 minutes.
A fast-charging smartphone charges with currents multiples of the battery capacity. Increased voltage is also used in the cable to eliminate losses on thin wires. This is not just a myth or another marketing trick. It is a real technological achievement that significantly reduces charging time and enhances the overall durability of the phone's battery.
The concept of fast charging is based on optimizing each stage of charging, starting with increasing the input power of the power supply. Fast charging standards, such as Qualcomm Quick Charge and USB Power Delivery (USB-PD), are designed to accelerate the charging process by increasing the energy transmitted from the power block to the phone.
Comparative Analysis
As of the time of writing, the fastest charging phone in the world is the Realme GT3 from China. This powerhouse supports a whopping 240W and fully charges the device in less than 10 minutes, to be precise, in 9.5 minutes. It returns 20% of the battery capacity in just 1 minute and 20 seconds – an incredible achievement.
Another Chinese smartphone, the Redmi Note 12 Explorer, takes the second spot in the list of fastest charging phone 2023. Its, 4300mAh battery supports charging speeds ranging from 120W to 210W. This is sufficient to fully restore the smartphone to operational status with a complete battery capacity in just 9 minutes.
Next on the list of super fast charging phones is the iQOO 10 Pro. This device supports a current of up to 200W and charges from zero to full in just 10 minutes. Its closest competitor, the OnePlus 10T, provides energy replenishment for the phone in 19 minutes, supporting a power of 150W for this purpose.
Finally, the top includes the Nubia Red Magic 7S Pro, and here we see that power doesn't always equate to speed. For instance, the charging performance here is lower than the previous model, at 135W. However, the gadget charges 4 minutes faster, completing the process in just 15 minutes.
You might argue that we also have the Redmi 12 Note Pro+ as the best fast charging smartphone. Indeed, the company showcased this beast with an incredible current of up to 300W, which charges halfway in just 2.5 minutes and fully in five minutes. However, the model released for sale has only 120W (surprisingly, but in this ranking, it is indeed "only"). When the version with the higher wattage will be available for widespread use is unknown, so we are keeping an eye on this phone for now.
As you can see, the fast charging smartphone list does not include heavyweight market players like Samsung or Apple. Indeed, these companies are not rushing to implement such technologies. As for Cupertino, this is quite explainable; until the process is thoroughly studied, users should not pin their hopes on such a surge for Battery Life.
Currently, the super fast charging iPhone supports only 27 W, while the flagship devices from the South Korean giant are equipped with a maximum current of 45 W.
Future Outlook
In just the last eight years, technology has not taken a step but rather leaped far forward, increasing the power from 20 to 240 W. Many analysts believe that such a leap will currently impact further development. Not in the sense that manufacturers will not strive to create the fastest charging phone time, but will aim to enhance existing solutions and make them safer.
It is assumed that this will be the task for the coming years. Most likely, we will see new efficient materials, possibly anodic and graphene batteries instead of Lithium Battery; improved built-in chips for power control, and other solutions for the fastest mobile charging phone.
