Different chargers have different wiring on the data pins (2&3) depending on the host device. My experience with Android devices is that most (not necessarily all) expect data pins on AC chargers to be shorted, while Apple devices expect to see a load across these pins. A number of Android devices I have had drop their charging rates when that load is encountered just as if it was plugged into a computer's USB port (but can't say for sure whether they all do).
