    I use a bold 9900 with .794 OS from China Unicom and if I connect the phone to the computer to recharge the baterry and use it at the same time (lets say make a call), it will drain the baterry of the phone.

    Is this normal? I had the same issue with the other versions of OS (.714, .746 etc) and I dont think that should happen.

    I never saw that kind of thing in any other phone I had.

    HELP

    It can be for two different reasons. A bad cable will not charge your device but I am betting the computer USB port does not have enough power to charge your device. Have you tried different ports? Also have you install the DM software, I think it powers up the USB ports for charging.

    May not be the OS but rather the USB port. Some ports have too little output to charge and support phone usage at the same time.

    It could also be the usb drivers are not loaded properly. Try re-install the appropriate usb drivers.

    I had a similar problem , i have 4 usb ports on my lappy , two on one side stopped working after a windows update , I found out that there was a driver issue and went into device manager and uninstalled the usb driver , and waited for windows to reinstall it with some generic driver , then the usb port was working , Initially when i plugged in my bb into the nonworking usb i was convinced something was wrong with the fone , but that was not the case , try plugging your fone to all the usb port , if it still doesnt detect the bold , then try the uninstall method , and then uninstall bbdm and reinstall bbdm them connect ur fone, that should solve it

    Thanks for the help. I'll try it on another computer 'cause even with DM freshly installed, it only charges if I dnt use the phone at the same time. I have a usb charger that does the same thing.
