Just a few days ago, Samsung officially unveiled its Galaxy S20 series at the Galaxy Unpacked event. As expected, the company launched three devices as part of this year's flagship lineup, including the Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra. All three devices are powered by either Qualcomm's Snapdragon 865 SoC or Samsung's own Exynos 990 chipset, they feature the latest LPDDR5 RAM, and compared to last year's flagships, they also include significantly larger batteries. The Galaxy S20 packs in a respectable 4,000mAh battery with 25W fast charging, the S20+ has a 4,500mAh battery with the same fast charging support and the S20 Ultra packs in a massive 5,000mAh battery with 45W fast charging support. While these numbers may not seem all that impressive compared to other smartphones in the market, they're definitely a major improvement for Samsung. But that's not all that Samsung has improved in the Galaxy S20 series when it comes to charging.
As per a recent press release from the USB-IF, the Samsung Galaxy S20 series are the first smartphones to receive certification based on USB Power Delivery (USB PD) 3.0 specification with the Programmable Power Supply (PPS) feature. Information about the certification was released by the USB Implementers Forum (USB-IF) today, which is the support organization for the advancement and adoption of USB technology. For those of you who aren't familiar with the USB PD 3.0 and PPS standards, the certification basically means that all three devices in the Galaxy S20 series will work flawlessly with third-party fast chargers as long as the chargers are also similarly certified. In effect, the Galaxy S20 and 20+ will work with certified chargers with a 25W output, while the Galaxy S20 Ultra will work with certified chargers with a 45W output.

Interestingly, the Galaxy Note 10 Plus (review) from last year also supported USB PD 3.0 and PPS, but it didn't receive official certification from the USB-IF. It's also worth noting that despite the certification several reviewers, including our own Max Weinbach, have reported that the Galaxy S20 Ultra doesn't seem to charge that fast, even with Samsung's first-party 45W USB PD PPD certified charger.
