[ftoz]

Hi i have x7500 and i use it as usb modem, when i use it over the night, modem stops due to the low battery. I think, that is a rom problem because i dont belive that consumation is higher thah charging. I use batery status and it shows + when use usb modem. It is same on x7510? Or no problem with usb charging?

It depends. If you use 1 Amp charger and your screen is on all the time then it consumes more power then the charger can supply. There are 2 Amp chargers, and those are more or less capable to cover the consumption of power while the X75xxx is on with screen on and doing some data transfer work. If you have traveled for long distance in a car with a map on your screen then you also can notice that X7500 can loose some power in spite it is charged.

But i mean charging through usb cable, when i have atnena connected to pc. I cant use it longer than half day. When i start internet sharing, battery status shows cca +200mA receiving, but when i leave it alone for half day and receive hspda data, it stops on battery empty and internet connecton is lost. So this i hate on athena. My old uni can go as long as i want and it was everytime at 100 procent battery when i dicconnet it.
