Measure current with a Branford Multimeter
If you use the "20A" socket, the meter must be set to "20m/20A" for a correct reading.  If the switch is set to any other position, the reading (if any) may or may not be meaningful.

Since you say you read 0.7 in both the 20m/20A and 200m positions, I expect the current is really 0.7 Amp.  That is a reasonable current for the phone to draw when charging.  The charging current will vary, depending on the state of charge of the battery, and can be limited by the charger circuit in the phone.
