I was on vacation and i used for first time my power plug (i charge my phone via usb and with usb cable only charging is perfect) and when i plug the phone my my touch screen stop responding. Is this normal? I've never noticed this issue before.
I had that once as I used the wrong charger, not the original one from HTC.
It was a charger from an old MP3-Player, where USB could be plugged.
Guess there wasn't enough voltage to it.
On my primary car I use a USB adapter to charge the phone. Prior to the SG2 I had a HD2 which (I think) charged fine.
If the phone has a zero charge I plug it in and it will automatically boot and the charge indicator shows charging but the battery indicator does not move for a while. Charging when using the phone never seems to keep up with the charge. After about 5 minutes the top indicator (when phone is on) starts to move and the phone will charge - although it seems pretty slowly.
The weirdness - when I plug in the USB cable to a laptop when its off the battery indicator lights up on the screen (pictagram) showing the phone is charging but it doesn't boot which is correct. What is weird is below:
In the car when you attempt to turn it off the phone with the long power button press and select the right options the phone will close down - you get the TMobile logo then the screen blanks out - then IT REBOOTS on its own!
Could under voltage be doing this? or is the cig port doing something odd with the voltage or amps? Know the USB port works and charges because I can charge it off a laptop, wall charger, computer etc and it works as it should. Its not the cable because I tried it on the computers.
Also tried a different usb/cig adapter - actually three and get the same results. Car only has 1 cig port.
Anyone have an idea?
Just put CM11 M8 on my kindle fire hd 8.9, love it, but have one question. I notice while it's charging, the lock screen will switch between saying charging/discharging. Meaning when the screen is off, as soon as I turn it on it says charging, then 1 second later it changes to discharging and stays that way...this is all done while the screen is locked. It looks like it is charging albeit extremely slow based on the percentage increasing...but is this normal behavior?
I've already tried two different usb cables.
What are you plugging the KFHD into? I have charged mine from 1A, 1.8A, and 2.1A ports, and while I don't remember ever seeing it switch back and forth between charging/discharging. As a side note, charging from a 1.8A or 2.1A port leads to fairly swift charging (I've used the original KFHD USB cable as well as AmazonBasics 1m and 2m cables with no change in charge time).
As a side note, I am also on CM11 M8
I'm running nightly builds with the Amazon 2.1 amp charger and have not seen this problem. Perhaps try a different charger to see if it still happens, it may be the charger itself.

Yes, I'm having the same issue. In my case, the unit reports 'not charging' even when it clearly is. I have no idea what the problem is, but as long as it charges, it's something to ignore.
It's no issue of CM - this is normal when you use low-power charger (effect is the same when charging from PC or Notebook USB ~ 500mA).
When you turn the screen on, power consumption is increasing and charger has not enough power to deal with it.
I recommend you to buy more powerful charger.
>1,8A chargers should charge easily even when the screen is on.
as an update; it seems that as of recently (I've switched from CM11 M8 to Liquid Smooth v3.2) the charging has slowed significantly. I don't use it all that often, so as of lately I've gone >1wk between charges. Two nights ago I plugged it into a 2A charger (intended for a Galaxy Tab) at 24% at 10pm, at 5am it had only increased to 77%. Last night, while plugged into my Galaxy S5's 2A charger it took almost all night to charge about 50%, and this morning it stated "99% Discharging" while still plugged in.
This is an interesting thing...
This is in regarding my several week old HTC10, which I got off ebay. Phone is S-Off and running stock US unlocked firmware.
The phone is not able to negotiate quick charge with the original HTC charger.
If I use my old HTC charger (from the HTC ONE - 5V 1A) or my ipad charger (5V 2A) or my computer USB port (5V 0.5A), the phone will charge, although slowly.
If I attach the HTC 10 charger when phone is 80% or more charged (ie not really using quick charge), the HTC 10 charger will work, and phone shows "charging rapidly".
But if I use the HTC 10 charger when battery is less than 80% (presumably when the phone is asking for higher volts) I get this:
phone shows "charging on AC" for half a sec or so,
then "charging rapidly" for half a sec,
then "discharging".
This repeats every second or so, and the phone barely charges. (Certainly much slower than my 0.5A computer port.)
I suspect that the phone is having problems negotiating a charging voltage with the charger, and cycling on & off repeatedly as it tries.
I guess this is due to either a bad charger, a bad cable, or bad firmware or hardware.
I don't have other USB C cables or Quick charge 3 power brick to experiment with.
Anyone has any idea of which is likely the culprit?
This is not a deal breaker as I plan to use mostly my 1A charger to slow charge in order to preserve battery longevity. But it would be nice to figure out why quick charge is not working.
Thanks all.
Update: Borrowed a Samsung Quick Charge 2.0 adapter, and it worked with my current cable. So I guess the adapter is faulty.
Recently, my P2XL has been acting up. For a while my charging has been intermittent. Thinking it was a loose cable, i tried others. It had the same problem. But recently, my charging stopped working at all. I swapped to a normal usb charger (a canakit pi 4 power brick) and it is working fine. For some reason, normal chargers are working, but when i plug it into a PD charger, i either get nothing, or in the case of plugging it into my laptop dock that's usb c just to test, it rapidly tries to charge and fails. I cleaned my pins with isopropyl alcohol and it still happens. any ideas? is my phone biting the dust? Also it doesnt charge with pd when the power is off either
