I've just got a new Galaxy S5 and I really love it. I'm currently anxious of its charging time. The moment I've booted the phone for the first time it showed around 51-52% battery. I've plugged the USB 2.0 (sad to see a USB 2.0 instead of USB 3.0 in box) and started charging through my laptop and at the same time imported contacts. Email is on Sync (15 min), wifi on, its been about 4 hours since the usb cable plugged in and is charging but still at 92%. Is it normal for the first time.
The problem I have is that the Wall outlet came with the phone isn't compatible with what I have at home and will make the adjustments tomorrow for that. So, I didn't tested it directly with its charger plugged.
