nexus 4 drains faster then it charges when plugged...

Hi,
i got a nexus 4 with kitkat, and it's plugged to charge on usb on my laptop.
I plugged it in at 75%, then shut it off (just the screen, not the phone) then 30 mins later, i check its battery, and it's down to 68% .... it's not downloading or anything, just plugged, screen off...
So it now discharges faster than it charges....

anyone experiencing the same issue ?

thanks

well
nevermind, the phone was plugged, and the little lightning was showing on my battery, but the phone was not charging... don't know why, i had to unplug it and replug it....
it's now charging again.
