How does mobile phone fast charging work?
This video explains the technology behind fast charging in mobile phones, from early phones with linear chargers to the most advanced high power Direct-Charge-Divide/2 systems. We discuss different battery types, special charging systems like Qualcomm’s Quick-Charge QC2.0/3.0 and the new USB-C Power Delivery charging systems, covering Direct Charge and Direct Charge-Divide/2 systems that can deliver charging powers up to 45W without overheating.
We hook up oscilloscope and USB-PD analysers to different smartphones like Galaxy Note 10+ to examine their charging behaviour in detail. We will also tell you about next generation smartphone charging technology like Direct Charge-Divide/4 and dual cell battery systems.
