oh? really? yeah, i noticed that the first 80% charges fast then slows at the last 20% so, are you saying that it's not always advisable to charge via usb? will it shorten my phone's battery life? i have this habit that i then remove my phone upon reaching 100% even when charged via usb. so how can i determine the "real full charge" when i charge my phone on my laptop? i don't usually bring my charger with me to the office. i just bring my htc usb cable.
