Try another usb port or another cable. if touching the usb phone plug your hear the disconneting / connecting sound on laptop, that could be a faulty cable or damaged phone port

the problem is that you're charging from a laptop. Use the original wall charger, that will always give you faster speeds than a computer. A computer can only give 0.5A of current from a USB port for charging while most low budget phones need 0.85A or higher while good phones like the 950 or 1020 need at least 1.5A to charge effectively -hence you should use the wall charger
