We discuss different battery types, special charging systems like Qualcomm\u2019s 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.
