Quick Charge 4.0 claims to extend
smartphone use for flagship smartphones with the
Qualcomm Snapdragon 835 chip by
5 hours with only 5 minutes of charging, going “5 for 5” according to
Qualcomm. With just 15 minutes of charging time, a 2,750 mAh battery is expected to be able to go from 0% to 50% charge.
Qualcomm is once again improving their Dual Charge parallel charging technology (now called “Dual Charge++”) to provide up to 20% faster charging and 30% higher efficiency at up to 5 degrees celsius cooler temperatures compared to Quick Charge 3.0, which itself featured improvements over the predecessor technologies
One of the most important changes though is the addition of
compatibility with USB Power Delivery (USB PD), which could not have come at a better time, following closely on the heels of
Google “strongly recommend[ing]” that devices only support charging methods that are compatible with USB PD in the new
Android 7.0 Compatibility Document (with a little hint that Google “might REQUIRE all type-C devices to support full interoperability with standard type-C chargers” in the future).
