Background:
I have had my Priv since November '15 (bought unlocked from shop BB) and I have 3 Qualcomm QuickCharge 2.0 capable chargers:
1. Aukey travel charger: https://www.amazon.com/gp/product/B0...UvbUpU12670052
2. Aukey 3 port wall charger: https://www.amazon.com/gp/product/B0...UvbUpU12670052
3. Nekteck car charger: https://www.amazon.com/Nekteck-Charg...UvbUpU12670052

I have several regular 1.2A USB chargers and a desk wireless charger (charges at 600mAh) that I use when I don't need to fast charge my phone.

Behavior:
All the above QC 2.0 chargers charge my phone at a max of 2140mAh (measured using Ampere app). The phone's charging indicator shows the battery charge percentage go up from whatever it was, to 100% (in less than 1hr). I typically disconnect the charger anytime after 95%, mostly immediately after it reaches 100%.
The phone starts discharging at an unusually faster rate and within 2 hrs, the battery drains from >95% to about 30%. This happens EVERY time I use any of these QC 2.0 chargers.

When using the regular chargers or the wireless charger to charge the phone to anything more than 95%, the battery drain is normal.

My conclusion:
The Priv software measures the battery charge incorrectly. It is possible that when the QC 2.0 charger is charging and supplying more amps, the phone thinks that the battery is charged, but at the chemical level, the battery isn't. Thus after the charger is unplugged, the phone starts showing abnormal battery drain, until the software measurement reaches the "true" charge level.

Has anyone noticed this behavior?

I don't have a QC. But i do use the old Playbook Fast Charger on the Priv. I have not noticed any oddball charge or discharge rates using it.

When I did own a priv, I never noticed any of these issues. I use several quick charge options. The nexus ten 2amp wall charger, an aukey qc 2.0 car charger, and the 2amp USB connection on my work truck inverter. All charged relatively as fast as one another and it would discharge at the same rate as if I used any other charging method.

Yeah, mine as well. Not to sure why this is happening..

Interesting.. I just bought this BlitzWolf QC charger a few weeks ago and everything seems normal, no weird discharges anywhere. STV100-4 on AAH505. Have you always had these problems or did they start after an update or something?

Interesting,

I got an aukey quick charge 3.0 and my device charges in an hour and 15 minutes more or less,

I get about 3.45 hours sot now during 12 hours usage which I think is okay but I used to get 4.5 hours and I thought it was normal wear and tear on the battery since my device is a year old.

Il go back to charging on the stock charger, my current battery has been done on with quick charge so il post screen shots tomorrow about this .
