    My new HTC One (m8) Windows/Verizon phone was taking a long time to charge.

    I purposely purchase chargers that output at least 2.1A per channel, and am careful about the cables, so I was puzzled.

    I noticed the Warn if slow charge setting, and enabled it. As you suspect, the warning popped up as soon as I plugged it in.

    I thought perhaps it might be the cable, so I retrieved the HTC charger, used my cable, and it worked fine (no warning). I found the original HTC cable, used it with my charger(s), and it failed slow charge warning. I then tried 3 other chargers -- from different manufacturers, all with the same specs -- and had the same results.

    The specs on the HTC charger say the output is 5V=1.5A.

    My chargers (and Ive tested this with several) have output of 5V=2.1A

    So what gives? Any ideas?

    No idea, although I posted a thread about a charger observation I had made.(http://forums.windowscentral.com/htc...servation.html) I'm using an old generic charger that outputs 800ma. So somewhat less than yours and it does indeed charge slow, but seems to be a benefit IMO as it also then discharges a lot slower. If I use the OEM HTC charger it charges quite a bit faster but also discharges faster. So was wondering if a slow or trickle type charge is better for maintaining the charge. I always charge overnite. BTW from around 20% battery remaining my generic takes about 4 to 5 hours to fully charge. The OEM does it in 1.5 hours.

    That's interesting. I just purchased my One 2 days ago and noticed the HTC charger is so slow. I keep using my battery pack that output 2.1a instead. But I also noticed the discharge is fast too. So its consistent with your observations.

    I have found this to be true as well, I just plug it in at work or evening and let the slow charge go but then a get a battery life on average of 2.5 to 3 days. I usually plug it in for a charge around 30 to 35 percent left so I actually could get more out of it.
    I have noticed I get a fast charge with the car adapter but that is just a default Verizon one that I got with the packaged accessories...
