USB charging problem!

leemaverickly · #1 (**permalink**) 09-21-2008, 06:09 PM

When I hook up the Diamond to computer tethering, the phone is always discharging. My Treo 800w does that too but HTC Touch is fine. I guess it's the design problem of the circuit. Does anybody else have the same problem? Thanks.

Try a different USB cable. I have several and some charge and some don't. This is true on both my old 6700 and the Diamond.

there's a setting in the phone where you can make the phone charge or not charge when plugged into a computer

its not that. try different cables, especiallythe stock one. use nuePower to check the discharge.

I will try a different cable. Thanks for the advice guys.

I tried 4 different cables I have. All were the same. When I connect the phone to my computer while I am tethering or calling. The discharge would be like 590mA and charge is 441mA so battery level keeps going down. Do you guys have any recommendations about what cable I should get?

i get about 441mA charging on usb with my HTC cable. and any other cable i try. your discharge is just surpassing your recharge rate so its falling back on battery.

what are you running? ive never a discharge that high.

I agree with that. Can you turn off some of your radio type stuff, like bluetooth, GPS, or WiFi? Your other option may be to use the wall charger, with is rated at 1A, rather than the 500mA available from most standard USB ports. I've also got a "double-headed" USB cable that takes two USB ports on the computer side and one port on the device side.

Another alternative is a docking station that has an AC adapter, as well as a USB connector.

Thanks for your replies. I don't have any applications on other than using PDAnet to tether or making phone calls.

If I don't do anything but just leave the phone connecting to the computer, it charges fine.

So just to be clear; if you run PDANet to tether, it won't charge (drains slowly). If you don't use PDANet, it will charge properly.

If that's true, it would mean that the juice required by the processing of the data, and/or the constant cell data communication is draining the battery, which makes sense. So you're back to trying to find a way to get more juice to the Diamond, which means either a docking station/AC adapter or dual USB plugs.
