The Infinix Concept Phone 2021 with its 160W charger are in for testing

Back in 2015, we announced the Battle for Fast Chargers, our first test of fast charging technologies. Back then, a typical USB brick delivered only 5W, and the most powerful charger tested peaked at 25W. Let’s just say things have slipped since.

The fastest charging system we have reviewed belongs to the Black Shark 4, whose power-brick pumps 120W out and can fully charge the 4,500 mAh battery in 19 minutes.

Now we have in our hands a concept unit that promises to reduce the charging time almost by half – Infinix Concept Phone 2021 comes with a 160W Ultra Flash Charge power brick, which aims to charge the 4,000 mAh battery in just 10 minutes, all while observing strict safety protocols.

Yes, the battery has a slightly smaller capacity, but it also has another internal structure – it is an 8C battery. We are not digging too deep into it now, but the C-rate numbers indicate the maximum current with which you can charge or discharge a battery.

And the current stone produces a lot of current, it peaks at 20V and 8A to reach a maximum of 160W current. We call it a brick, but the charger itself uses GaN (gallium nitride) and SiC (silicon carbide) components, which makes it quite compact for its production. It weighs less than 200 g, which is much smaller than a typical portable charger in the 100+ Watt class. This Infinix charger supports multiple protocols, so it can actually charge laptops as well.

Infinix Concept Phone is also a demonstration tool for a few other technologies that the company is working on. One is immediately visible when you connect the phone – a line of green light connects the USB-C port and the circle in the middle of the “NOW” stencil on the back. It pulsates while the phone is charging.

This is a piece of electroluminescent film that can serve as an interesting alternative to the now mostly extinct message LEDs. It is thin but covers a large part of the back, much larger than can be easily covered with traditional LEDs.

The phone can undergo another visual transformation thanks to the solid electrochromic film. The back of the phone is usually a slate gray color, although it changes slightly when the light hits it at different angles. However, the phone may turn its back to a light blue color.

Infinix has positioned this as a kind of messaging system – if you have a missed call, your phone will be blue. In fact, it starts to turn blue as soon as the phone starts ringing.

As the name makes clear, this is a concept unit, it’s a demonstrator of Ultra Flash Charge technology, just like the chameleon was back. So this is what we want to test – how fast can the battery hit 100% charge?

While this device will never be sold to the public, its charging system may be shown in upcoming Infinix flagships. What about the glowing, color-changing back? That too maybe, even though we do not have any solid info. But we will soon share our thoughts and test results from our time with Infinix Concept Phone 2021.
