World's fastest smartphone charging tech goes 0-100% in under 5 minutes
The phones are hooked to a massive 320W charging brick
What just happened? Realme just took the crown for the world's fastest charging solution with its new 320W SuperSonic Charge system. Unveiled at an event in Shenzhen earlier this month, the technology can power up an empty smartphone battery in under 5 minutes. Supported phones can charge to 26% in a minute and to 50% in less than two minutes. A full charge takes 4 minutes and 30 seconds. This beats the previous record holder – Xiaomi Redmi's 300W charger from early 2023 which took nearly 5 minutes.

Tesla rolls out first-ever Cybertruck with dry cathode battery following years of development
If the gambit pays off, Cybertrucks could eventually become cheaper
In context: Tesla set the stage for this milestone back in 2019 when it pulled the trigger on a major battery tech acquisition. The EV maker scooped up Maxwell Technologies and its promising "dry electrode" coating process, originally developed for supercapacitors. At the time, Tesla was still relying on partnerships with suppliers like Panasonic for cell production. But the Maxwell deal signaled Elon Musk's ambitions to bring that technology fully in-house.
