I am having a strange issue on my Xperia S I would like to know if this is impacting other people. I am running Build 6.0.A.3.67 (FR) and when I charge my phone through the USB Hub (externally powered) it will actually begin discharging instead of charging in certain circumstances.
Here is how it can be reproduced:
1) Plug phone into USB Hub with PC (W7x64) in Standby mode - Phone will show as being charged by AC and battery will charge without issue.
2) Wake PC out of Standby - This will cause the Phone to switch from being charged in AC mode to USB mode but phone seems to continue to charge.
3) Put PC in Standby mode again - Phone will stop charging and will actually begin to discharge at a very fast rate 5% / hour.
To check actual charging status (charging AC/USB or discharging) go to Settings -> About Phone -> Status
To get the phone to go back to AC charging status it is necessary to unplug the USB cable from the phone and re-insert it and it will go back to charging in AC mode. It seems there is something in the phone software or kernel that blocks going from USB mode back to AC mode without unplugging the USB cable.
I have tried 2 powered USB hubs (D-Link and Dr. Bott) and same issue with both. I have tried 2 different USB cables and tested the same steps using my HTC Desire and Flyer and issue only occurs on the Xperia S. 1 difference is the 2 HTC devices always show USB charging mode and never AC but they continue charging without issue as PC goes from Standy to Actve to Standby again.
Can someone else please try to see if their phone also behaves the same way when following the steps above? Does anyone have any suggestions on how to fix? My only option currently is to charge only with an AC charger and not with the USB cable connected to my PC USB hub or I can wake up with my phone dead in the morning.
Thank you for any advice (sorry for the long post)

So I went out and bought a 2nd USB cable to leave at work to charge my phone. But for some reason the USB cable I bought doesn't charge the phone...instead it drains the battery..??? The light is on and the icon shows it is charging when I have the USB cable connected and I can even mount the SDcard with it. But the battery percentage slowly goes down. The USB cable that came with the phone works fine without any issues.
Is there something special about the stock USB cable? Do I have to buy a certain type of cable to make charging work?
I bought another two cables, even used a Motorola USB cable but never noticed that... it never happened to me.
My guess is:
Fact:
- charging through the pc USB port is so slow, to get full charge you need 6-8 hours compared to 1.5-2 hours through the wall..
Scenario:
You are using your phone or running heavy application while charging it so it drains more battery than charging ..
Just a guess.

1. My phone never charges when the phone is completely off. It seems to only charge when in Android. Is this normal?
2. How do you enter that rapid battery recharge service mode from the boot menu's? The mode I'm referring to is when the phone has not booted Android but all it's doing is recharging the battery with the screen off. If you press the power button, the screen turns on for a second showing you the battery level.

Mine does that by default. When I plug it in to charge when three phone ifs switched off, it well show me A image of a battery with water like thing inside our and the charge level..
Did you change something in the phone?

I decided to try a USB wall charger and it's now showing that image of a battery.
Do you ever see that battery image when you plug the phone into a PC USB Port? My PC has decent powered ports (almost 1000ma) but it just won't charge the phone when powered off. But charges when in Android.
I basically only flashed a retail ROM and updated the Radio.
Something to check into is the USB cable that you are using...swap it out with another one.
Speaking from experience with a different Android (DInc), I know I have plugged it into some cables that provide just power via USB (no data) and then I am guessing there is the possibility that there are some that provide data and no power.
The USB cable is perfectly fine, I tried another cable anyway and the same thing happened.
I tried three PC's including a Desktop with decent USB ports, none of them charge the phone while turned off. I tried two USB Wall Adapters and both can power the phone while off.
So it seems that if the USB Port cannot supply more than say 1.5Amp or 2Amps (basically all PC USB Ports), it won't go into battery charge mode.
Basically, my problem is, the wall charging and USB connect are reversed. i.e., I connect my wall charger, its showing as USB mode and when I connect the cable to a PC, its showing as AC Charging. I tested with Ampere app and when I connect to AC Charger, it is drawing only around 300mA(like it would do if connected to USB) and its drawing around 1.5A(like it would do when connected to wall charger) when connected to USB PC.
I have been having this issue for quite sometime and recently, I had upgraded to Marshmallow through OTA upgrade. I thought atleast this upgrade would fix this issue but I am still facing the same issue. I even contacted the customer care and nothing useful advice other than restoring to factory settings was suggested(which I tried and didn't work).
I guess it should be some software issue but don't know what it is or how to fix it. Any inputs would be welcome.
Device not charging when I plug into charger but it charges when it is connected to PowerBank. It is not charging in any other charger except PowerBank. I have tried factory data reset but no use. Should I download any room for solution. Please suggest me and kindly help me to solve this issue
sounds like your wall charger went bad, try another USB charger or computer to test (though I don't recommend charging on computer since it has low amps, and the phone needs 2A~ to charge properly), also try another micro usb cable.
there is nothing special about a power bank since it uses a standard USB port (with the exception of the data lines shorted).
Ok so I started having a weird charging issue with my Xperia Z2, a few months ago when I plugged the phone in to charge and noticed it was constantly showing it was charging and disconnecting non stop (basically this here Xperia Z2 charging disconnect)... first thought was maybe my usb cable (original Sony cable) was buggered but nope, plugged in my Xperia Z5 on the same cable and it charged fine, so I tried my magnetic charger on the Z2 and nothing, no charge at all. Eventually when the phone died completely then I was able to get it to charge but not without some issue, when plugging in it would still do the same thing, charge and disconnect constantly, it would take unplugging the cable and plugging it in again a few times till the phone would eventually charge and even though the charge would show 100%, when I turn the phone on, the battery percentage would vary anywhere between 80%-95% and it would discharge very fast.
I figured it may have been my battery as I have been using the phone with an expanded battery since like 2020 and thought maybe thats it for the battery. Eventually got around to getting a new battery this weekend and the phone still does the same thing but its a bit different now, connecting it with my Sony cable still did the same thing when connected to the wall charger, charge and disconnect constantly. Then I thought maybe it could be a software issue so I connected my phone to my PC using a different usb cable to copy some stuff to my PC before resetting the phone to see if that helps...connected it and it was charging...so I take my Sony cable and connect it to the PC with that and it was charging...unplugged the cable from the PC and plugged it into the wall charger and it was charging and disconnecting again. Plugged it into the PC again and started charging. Tried the other usb cable with the wall charger and it did the same constant charging and disconnecting. I know the wall charger is working fine as I am charging other phones on it too with no problems.
I try a third usb cable on the wall charger, this is a real cheap low amp cable, my Z2 starts charging with it almost normally, painfully slow but it was charging. Now I say almost normally because when it charges to around 90% then it starts doing the constant charge and disconnect again. Also the battery doesn't discharge as fast as it was doing before but still a bit fast.
I want to try flashing a new rom, stock and custom to see if any of those might work.
Would any one have any idea of the issue or experienced anything similar and was able to fix it? Any help any one
In the past I had a similar problem, try to clean the Usb port on phone and try again.
Kindly regards
I remember reading something about the live kernel being involved in charging. It makes sense for this to break charging while completely empty. To charge at full speed you need the kernel to be running, but to get the kernel running you need power, the trickle charge you get without a kernel isn't enough to keep up with the boot process, so you end up in a loop of no power. I have not tested if another kernel fixes it, but it is currently broken on my device.
