I own the HTC One 2013 for almost a year now.
It seems that starting the 4.4.2 update something went wrong, maybe in the background services of Google.
I've always used agood charger, I always use the same apps and I even use rooted S-Off device with a kernel supporting the quick charge, but still the battery drains while charging and navigating.
To compare, my wife's Samsung S2 with still Android 4.2 if I'm not mistaken, is using the same charger with the same driving setup of Waze and such and it charges great!
