Along with the reveal of the Snapdragon 835 today and its production on Samsung’s 10nm FinFET process technology, Qualcomm is also announcing the release of Quick Charge 4, an upgrade to the company’s successful fast charging solution that improves both efficiency and performance. Based on the information provided by Qualcomm, Quick Charge 4 will offer “premium phone users” some impressive charging rates.
- 5 hours or more of use in 5 minutes of charging
- 50% battery charge in 15 minutes or less
Those time metrics are based on talk time, not VR playback or gaming or browsing, meaning you can get 5 hours of additional talk time in 5 minutes of Quick Charge 4 charging time. While I think other battery life metrics (like browsing time, idle time) would provide additional context for these claims, even these numbers should impress potential buyers.
Using an updated version of its voltage negotiation protocol INOV 3.0 (intelligent negotiation for optimal voltage), Quick Charge 4 will intelligently determine what voltages are available from the compatible charger and which voltage is the most appropriate based on temperatures and current battery state. QC 4 will offer 5V, 9V and 12V charging options at 3-5A!
Quick Charge 4 will offer 30% higher efficiency along with the 20% faster charging and integrates support for USB Type-C connections and USB-PD support. (Which is important based on the noise Google has been making recently.) New PMICs (power management ICs) from Qualcomm, the SMB1380 and SMB1381, will be shipping this year and deliver low impedance peak efficiency of up to 95%.
And of course, no smart phone platform launch will go by for the foreseeable future that doesn’t mention safety.
In addition to providing the most consistent in-box and out-of-box charging experience, Quick Charge 4 comes with advanced safety features for both the adapter and mobile device. Protection is implemented at multiple levels and throughout the entire charging process to more accurately measure voltage, current, and temperature while protecting the battery, system, cables and connectors. An additional layer of protection is also being added to help prevent battery over-charging and regulate current throughout every charge cycle.
It’s worth noting that Quick Charge 4 won’t be limited to only the Snapdragon 835 processor, though other integrations haven’t been announced just yet. I have a feeling we will hear more at CES in January. The Quick Charge ecosystem has been steadily growing with hundreds of charging accessories and devices shipping today with QC3/QC2 and I expect that will continue with Quick Charge 4.
