Wireless charging’s convenience is amazing, but the quickest way to power up remains through a wire. Today, Qualcomm is announcing Quick Charge 5 with a slew of speed and safety enhancements.
Qualcomm announced that Quick Charge 5 is the “first commercially viable” fast charging solution that supports over 100W and is available for phone makers to use today. It’s emphasizing larger availability for many manufacturers over competing, single-OEM offerings.
a battery of capability 4500 mAh is charging from 0 to 50% in five minutes, with a full top-up in 15 minutes. Compared to Quick Charge 4, it’s 70% more power efficient, or Xx faster. That’s 10 times more power delivery compared to its inaugural fast charging tech from 2013.
There is support for 2S (stacked) batteries and 20 Volts of power supply. The Qualcomm is releasing new power management ICs with the Qualcomm SMB1396 and SMB1398. With that size of power running, there are a number of “extreme safety measures.”
Quick Charge 5 incorporates 12 separate voltage, current, and temperature protections, with USB-input overvoltage protection at 25V and external power controls beyond 30V. Quick Charge 5 also runs 10°C cooler than Quick Charge 4.
A key live is Qualcomm’s new “Smart Identification of Adapter Capabilities.” this can monitor and verify the particular — rather than simply trusting — limits of a connected charger to regulate current, power, and voltage behavior. There are numerous levels of protection with reference to voltage, current, thermal, and timer at the handset-level.
In terms of ecosystem support, Quick Charge 5 is backward compatible with version 2.0, 3.0, 4, and 4+, with the chart below explaining the permutations. Qualcomm notes how it also takes advantage of both Normal USB and Type-C. These Quick Charging 5 charging bricks will also work with laptops and other form factors.

Quick Charge 5 is supported by the Snapdragon 865 with 865 Plus, as well as “future premium-and high-tier Snapdragon mobile platforms.” Xiaomi will be one of the first partners to leverage the technology in the upcoming months.
