Current versions of iOS won't allow USB communication with a device you haven't explicitly authorized, and will require you to unlock your phone if it has been locked for more than an hour (by default at least). I think Android has similar restrictions.

If you're still worried, just use a regular outlet to charge with a charger you bring. I do that anyway, since many public USB ports may not provide the full 2A that the phone can take...and newer phones can take even more with the correct charger.

Does the current version of iOS even allow USB charging of a device without having explicitly authorized the phone's USB cable connection to a device? Or is that more of an issue when using third party USB cables than when using Apple's own cables?
