I have noticed that the note 2 sometimes considers AC Adapter as USB.
Thus the charging output reduces.
Is someone else also facing the same issue? Is there a solution?
Nope, it won't act as USB. Basically AC only connect to + and -. And the data is left blank.
Out USB port in PC has 3 connected

For me it does acts as USB sometimes.
I plugged the phone to USB port and then again to AC adapter.
The phone this time recognised the AC adapter and the charging output increased.
How are you measuring the charging output?
It happened to me once. Fixed it by unplugging then restarting the phone then it showed it as AC when I plugged it again. Don't know how it happens, but it seems a rare occurrence (for me at least).
i also feel that is why sometimes it keep charging slowly...anything to do with usb debugging enabled?

Sometimes my phone will not charge when connected to the wall or my computer. The problem usually goes away on it's own, but when I need to charge I generally need to charge.
Sometimes I cannot access my phone via USB on PC either.
Only with data to and from the computer. No charging issues at all.
I've never had issues when plugged in to computer (USB). I frequently have issues when plugging into wall charger, but I think I have a bad cable. Phone will recognize charger connect, sit for a second, and lose the connection. Charging stops while cable is in. I bought a cheap cable on-line for the wall charger. I guess you get what you pay for....!
I have issues with usb connnect to computer since flashing cm6 8/13 nightly. Will not charge or mount usb.
Restoring back to 8/11 seems to fix issue but can't seem to get any newer nightlys to work or rc2.

Kind of sounds like a loose connector. I bought some micro USB cables from monoprice and the size of the connector was just a tad smaller than the plug for the phone. So if the cable wasn't plugged in and propped up in a certain way, the phone wouldn't charge. I just bought some new cables from monoprice (the ferite core ones) and problem solved.
I guess when this happens to you, wiggle the cable a little and then hold it for a few seconds at a certain angle and see if it starts charging... if it does then you know you need a new cable.
I was having similar issues and with my sd card permission issues I simply uninstalled my usb drivers and my removable disc drivers for the phone on the computer I think there was like 3 sets and haven't had an issue since.
I had recently purchased the C6502. At work I do not have AC power outlet to charge the phone. So I generally used to charge my old smartphone (LG Optimus 4X HD) with a blackberry USB cable. I used to charge my old phone by connecting to the monitor's USB port using the blackberry cable. Though the phone showed as "Slow charging", it served the purpose.
But now using the same Blackberry USB cable and the same USB port, if i try to charge the C6502, it just lights up the screen and does not show any charging indication or the notification LED light.
Am I missing something here or the phone charges only with the original Sony provided USB cable?
Note: The same USB cable and the USB port work perfectly fine for other smart phones my colleagues are having like Galaxy grand, Lumia 610, HTC Desire SV etc. Of course when connected to the usb port all these phones are showing as slow charging, but they do charge slowly. But my XZL does not even charge. So I am definitely sure the cable and the port are perfectly fine.
Is there a way I can charge my XZL with the USB cable using the USB port?

Let me explain it more clearly.
At my work the USB ports on the CPU are disabled. But the monitors are having USB ports which can be connected to the CPU through another cable, so that USB devices can be connected to the monitor's USB ports insteading of leaning till the CPU under the desk. But those ports are not connected to the CPU so the ports on the monitor just act as a power source but not as data source. So we use the monitor's usb ports for charging our devices like phones, ipods etc.
As i had already told that my XZL screen lights up when connected to the port using the blackberry cable, but no indication of charging as well as no LED light. Same case with another colleague's Xperia SP.

as simple as your device does not detect any pc therefore it doesnt accept charging depends from phone to phone

So sony does not support "chaging only" mode using USB cable. How pathetic !!!. Supposed to be a "Smart phone" but really do not understand why cut down basic features.
Can anybody confirm if this cut down of a basic feature is a standard for Sony phones?
No buddy usb charging works when pc is on!i checked it doesnt charge when main supply is on bt cpu is off but it charges when cpu is on

USB charging
I have observed two things -
1) Yes, it does not charge in some cases. I have a power bank cable, with this cable it charges for some time but then it just stops charging without any reason. If you reinsert the plug, it starts charging again.
Other times, it does not charge with USB ports, for example my car music player's USB port. But what I have noticed is, if USB connectivity mode is changed from MTP to MSC or vice-versa it works.
Also some cables do not have two spring notches, and fit quite loose. In such cases pushing cable vertically up or down gets it charging again. But this is very very rare case.
2) I was not able to charge it from front USB port of my PC, but when connected to back USB port, it was charging fine.
My conclusion is, it does not charge if charging rate is too low or mode is incorrect.
I would suggest, try with original Sony USB cable in your office and check if it works. If still it does not, change connectivity mode. Else its a cable issue(not exactly, but phone and cable have some mismatch).
PS - I had similar problem with my chinese tablet. Out of more than 5 cables, It charges with only one cable from Nokia(it does not even charge with original tab USB cable ). I think there are separate data pins and power pins. But data pins can double as power pins. I think there was some damage to the tab USB pins, because of which data pin no more works as power pin and hence it does not charge and requires cable having power pins. Can somebody throw more light on this?
Relax its just u need a pc on to charge it it happens in my case too n my phone works fy9 with any cable

That's something new to me.
Before with my Galaxy S4 I could charge the phone easily when I turned my PC off. I have set in the BIOS the option that allows to power the USB ports while the PC is off for that. It worked perfectly for my S4 as well as my tablet. But somehow it doesn't work for HTC 10. As soon as I turn off the PC the phone stops charging. What's going on? Is the USB-C the reason that happens?
(I am using a xiaomi microUSB to usb-c adapter)
I'd assume that it's not getting enough power to charge the HTC 10 now.

But is the power given to the USB port any different to when the PC is on? There is a setting in the BIOS to keep the USB ports powered on.
If the power given to the USB ports is the same when the PC is off and on then that shouldn't make any difference. Do you have any source that says the power (amps/volts) given to the usb ports when the computer is off is different?
Ok. I've did a bit of a testing and found out that if I turn off my computer while the htc 10 is connected then as long as the computer powers down the charging stops. But when I disconnect it and reconnect it the charging goes back. It might be that the "USB mode" is breaking the charging because when I attach the cable after the computer is powered down I get the notification that the charging is slower than usually which is fine and I know that will be the case (USB 2.0 gives only 500mA instead of 2A that the wall charger will give).
Boy, I wish I knew a way how to make this break when powering the computer down not occuring as it's a pain in the butt to have to reconnect it again.
So.....
I connected +5v to the usb ground pin on my phone and connected real +5v pin to ground.
Now my phone refuses every charger claiming that it is an "invalid charger type" and that I should only use the official charger that came with my phone. (which I do)
There was also some error about "charger suspend detected" (or similar).
The led still lights up when connected to a charger even when not charging.
It turns off ~5sec after disconnecting the charger (as opposed to turning off directly)
Sometimes the led doesn't light up at all and dmesg spews a bunch of errors.
Also when connecting an usb otg cable, it doesn't add the 2 usual devices (usb 2 root hub and usb 3 root hub) to the list of usb devices (aka output of lsusb?).
It adds those 2 devices only after connecting a to a normal charger and then to the usb otg cable.
The usb otg cable is always supplied with voltage even when there is no other usb device connected to it.
However connected devices aren't being recognised anyways except when connecting to a powered hub or using a Y-cable.
MTP, UMS and ADB all don't work.
(fastboot not tested yet)
Charging still works in 3 ways:
Shut down the phone and charge as always.
Connect the phone with an otg to a powered usb dock.
Connect the phone to to Y-usb otg cable and connect that to power.
Any ideas on how to get everything back to normal ?
Or at least how to get adb working (over usb)?
Just in case:
DON'T TRY TO REPRODUCE THIS ERROR JUST TO GET Y-CABLE CHARGING WORKING.
Hy guys. I am trying to make a dashboard install, and eveything went well ( I did the battery mod, installed the Timur's Kernel). All worked good, the tablet went to sleep when i stopped supplying power to the OTG Y cable (only stopped the power, NOT unpluging the OTG cable from the tablet). When I wanted to clean the setup, I once again powered the tablet and expected to shut down when the power was no longer provided, but surprize, it showed that it was still powered, and it kept showing that until I unpluged the OTG cable.
I started a hardware debug, checked the voltages, checked the cables etc. I tryed with a normal usb cable, that one worked ok (the charging status changed to not charging, the tablet stayed awake because it is not an OTG cable, and Timur's kernel needs a OTG cable for the FI function to be enabled). Then I tryed connecting the powered OTG cable, remove the power (still showing that the battery was charging), and then cut the ground wire that goes to pin 4 (SENSE), which made the tablet think it was not charging anymore.
Have any of you encountered this issue before? Have you found any solutions? I am going crazy here.
