To diagnose a faulty charge port. remove motherboard, plug into USB power and ran the multimeter along the pins on the dock connector (Where its soldered to the motherboard). if you get a reading of around 5V on 1 of the pins, then the dock is fine.
 
To test if it is battery fault -

You can attach the DC power supply to the battery connectorconnector (on motherboard). Just use multimeter to figure out which pin is gnd--(continuity with gnd shield on board). Attach negative lead to gnd pin (LEFT 4pin for the ipad AIR), and positive pin to the outermost pin on other side(RIGHT 4pin for ipad AIR). IF YOU USE ALLIGATOR CLIPS, USE WILL NEED TO MAKE SURE THE POSITIVE DOES NOT TOUCH THE SHIELD UNDERNEATH. CLIP IT ON THE CONTACT ITSELF.

. Apply 3.8V. Start iPad via power button (for mini this requires a functional solder joint at home button flex). I USED 5V with DC power supply its ok. DO NOT SWITCH ON POWER YET

Plug in the LCD apply DC power and nowNOW plug in the USB cable - should see apple logo hopefully - Remember before removing or plugging in LCD, remove the power otherwise you may end up burning the backlight circuit :(

Replace with new battery = Sometimes new batteries will not work either because they have lost there charge. they need to be at 3.7V to power up the device. if not you can charge a battery by connecting the DC power supply to battery terminals again to get it up to 3.7V
 
if that doesnt work, you can send the motherboard in for repair

A healthy mini will consume something like 100-300 mAmps of current. Too low = something on board is closed that should be open. Too high = something on board is open that should be closed = short.
 
good luck!

From here it could be battery or u2IC or some other components/chip
