Unable to charge or connect to PC - Galaxy S II Q&A, Help & Troubleshooting

Hi, i tried charging my phone and it will not charge unless i pull out the battery and reconnect it. I need to do this everytime i need to charge it.
It is also not recognized on my PC. Help?

Try to flash the stock rom maybe it could help you

Could be a problem with the usb cable, or your usb flex

USB Flex could be the reason :/
I tried other usb cables on the phone and its still the same result. I restored back to stock rom and its still not working.
The only way for me to charge the phone is to turn off the phone and plug the phone into a wall charger and let the phone charge while its off.

Strange USB charging issue

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.

Battery won't charge when phone is off

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.

[Q] Huawei Y300 (U8833) only turns on and works, using a usb cable not battery?

Hello, my Huawei y300 (u8833) only turn on and works while I plug in my usb cable either (charge). My phone doesn't turn on when i press the power button and I'm on just my battery, amazingly it turns on instantly after i plug in the usb charger and remove the battery. So i got a little tired of having to plug in my phone all the time and not use it on battery. Any help? I dropped my phone 9 months ago and it didn't work back then but i never tried the usb cable on without battery. But now after 9 months i plugged in usb cable and no battery and *boom* it works. Any advice as to what is going on? Can i ever get it to work from my battery? (BTW there is a red notification light (not blinking) if i put battery in along with usb cable. Thanks for any help.
Update: Somehow its charging my battery!
Update: (PS:I'm rooted and have cwm)
Update: I'm fuc*ing stupid, its now working on battery! Sorry to have waster your time

Kenzo dead usb port?

I charged the phone in the morning, everything was fine I didn't drop the phone or even bump it, nothing happened to it.
When I came home and plugged the usb in it didn't charge, I tried several cables and chargers but still nothing.
The OEM charger makes beeping sounds when the phone is plugged, I tried connecting to pc with fastboot mode but still didn't recognize.
Tried to charge the phone off\recovery\fastboot nothing works, it still has 75% battery and it's holding the charge fine.
Tried the same cables and chargers on a different phone and everything works porpely.
If I replace this part will it fix the issue?

Poco won't charge

When phone still had battery and I connected it to charger it didn't do anything. I have tried different chargers, cables even charging through PC.
If I turn it off and connect it to a charger it turns on shows battery percentage and then this process just loops as seen in the video.
