Infinix Concept Phone 2021 Demonstrates 160W Fast Charging Technology

Fast charging technology is an alternative solution to the growing dependence of humans on smartphones. Instead of using a thick smartphone with a large battery, the alternative is that we can use a typical smartphone equipped with fast charging technology so that the required battery recharge time can be shortened.

Infinix Concept Phone 2021 Demonstrates 160W Fast Charging Technology

Fast charging with 30W, 45W, and 65W outputs are standard nowadays, but smartphone manufacturers certainly won't be satisfied and stop there. They will undoubtedly continue to rotate their brains and explore new techniques so that their smartphones can be recharged faster. The latest example is Infinix.


At MWC 2021, the Hong Kong manufacturer showed off the Infinix Concept Phone 2021. The advantage? Fast charging 160W. With such a large output, Infinix claims the embedded 4,000 mAh battery can be fully charged in just 10 minutes, and they don't forget to include a demonstration video.

According to Infinix, this 160W fast charging technology can be realized thanks to 8C batteries, which are claimed to have an internal resistance 18% lower than 6C batteries. Infinix explains that the C numbers indicate the charging speed and discharging of a lithium battery, while internal resistance refers to the intensity of heat produced.

Also important is the Super Charge Pump technology, responsible for converting voltage from a USB-C port to a voltage directly received by the battery. Infinix claims a conversion efficiency rate of 98.6%. Higher numbers are better because less unconverted power — which is heat — will be less.

Infinix wants to make sure that the device remains and despite receiving a very high electrical power output. In total, there are 20 temperature sensors embedded into this device—everything to ensure that the temperature of the device remains below 40° C during the charging process.

If the device passes these temperatures, or there is electromagnetic interference or excessive voltage spikes, the device will automatically activate its protection mechanism to prevent damage. In total, Infinix claims there are 60 protection mechanisms they embed in these devices.

No less attractive is the included 160W charger head, which is very compact thanks to the use of Gallium Nitride (GaN) and Silicon Carbide (SiC) semiconductor materials. Alternatively, the device can also be charged wirelessly with a maximum output of 50W using a compatible charging pad.

Infinix is undoubtedly not the only one busy developing fast charging technology with extreme speeds. Last year, OPPO showed off its 125W fast charging technology. Then not long ago, Xiaomi also had time to demonstrate fast-charging 200W. Even so, there is nothing that consumers can enjoy at large. Infinix even blatantly named this device concept phone.

The name of the concept device, of course, there are also several other experimental features. The most attention-grabbing is probably the rear panel which can alternate colors between silver and blue by utilizing electrochromic and electroluminescent techniques. Then when the device is charged, the letter "O" will also light up in green.

It's also the first time Infinix has embedded a periscope camera on the phone made of it, with an optical zoom option of up to 10x or a digital zoom of up to 60x. The device is also equipped with an AMOLED screen with curved edges that almost cover the entire left and right sides of the phone, leaving only a tiny amount of space for the power and volume buttons.
