The news that the HTC One A9 is being updated with Quick Charge 3.0 in Europe is enough to raise hopes of HTC One M8 and M9 owners that they could offset poor battery life with rapid fill-ups.
Bright news for owners of the midrange device may not be so for owners of the flagship devices as Qualcomm’s Quick Charge 3.0 is only compatible a few chipsets.
Apart from the latest Snapdragon 820, the 620, 618, 617, and 430 chips support the latest feature.
The HTC One M8 is powered by a Snapdragon 801 while the HTC One M9 runs on a Snapdragon 810, so unless the list of compatible SoC models is updated to include the 810, 801, or even 808 chips, previous-gen HTC users have to stick with Quick Charge 2.0.
Quick Charge 3.0 does however support more range of voltages, from 3.6V to 20V. It is also backwards compatible, meaning that you can pair up a Quick Charge 3.0 device with a Quick Charge 2.0 charger or vice versa, though the 2.0 supported device cannot go any faster than its own 2.0 ceiling.
The newest feature is also compatible with all sorts of connectors, be it a USB Type-A, microUSB, or Type-C. It charges 38 percent faster than Quick Charge 2.0 and four times faster than normal charging.
