Hi guys. I plug my Touch into the usb cable and into my computer all day whilst im in work which ensures the battery is topped up to the brim all day. but i've noticed that when i run some apps, like the SHOUTcast radio app in particular, the Touch battery will run low until it runs out and the usb itself is soully providing the power. but why wont the battery charge too? if i switch off the app then i can recharge the battery. has anyone else noticed this?
