Hi,
Has anyone tried to charge the Note 3 with a Qualcomm Quick Charge 2.0 charger and does it charge significantly faster?
The reason I ask is that our phone's processor, Snapdragon 800, is listed as supporting Qualcomm Quick Charge 2.0:
https://www.qualcomm.com/products/sn...processors/800
The technology works by ramping up the charging voltage when the battery is low, and slowly reducing voltage as the battery fills up.
This is exactly the same technology which the Note 4 uses and dubs "Adaptive Fast Charging".
The latest Qualcomm Quick Charge 2.0 chargers charge at:
12V * 1.5A = 18W
9V * 2A = 18W
5V * 2A = 10W
(voltage is reduced as battery charges up).
You can see the voltage/amperage of the charger written somewhere on the charger.
Chargers that are 5V/2A only (e.g. stock charger) are not quick charge 2.0.
This is not to be confused with USB 3.0 charging (which is only ~5V * 1A = 5W from PC), or 2A chargers (5V * 2A = 10W from 0 to 100%).
Our Note 3's chipset supports this, but it won't be very surprising if Samsung disables this on the firmware or kernel level.
If anyone has tried charging the Note 3 with a QC 2.0 charger, your input is much appreciated!
