Charging dependent on cable?
My HTC one X charges on my laptop faster than a specific Belkin wall charger I purchased.
I am inclined this could be due to the USB charging specification of the OneX after reading this review on Amazon.co.uk on a specific battery pack.
(since I'm new I cannot post a link, but it can be found on amazon.co.uk and searching for TeckNet® iEP387 7000mAh Dual-Port, review by Keith Dunnet)
Basically Keith Dunnet says that there are specific "USB dumb charger standards" or the spec named "Dedicated Charging Port". He states that per the spec, a USB device on a standard downstream port should not consume > 100mA unless it is enumerated and configured to do so; since this can't happen on a "dumb" charger, the shorting of D+ and D- signals to the device that it can assume it has a Dedicated Charging Port and go ahead and draw 1A if it wants.
So do we need "charging" only cables on non-HTC wall chargers to speed things up? Anyone any thoughts?
