This Tristar IC talks to the charger before allowing it to charge the phone, and often causes slow charging, no charging, or death after being plugged into a fake charger. NXP 1610A1. U2 in the iPhone 5C/5S U6000 in the iPad Air U1300 in the iPad Mini Retina 2/3 1610a3 will work better, is compatible, and fails less than this chip.
