i saw "thousands" of posts saying " pads behind battery don't have esd protection"
FALSE
the ESD protector chip is in place but between usb transceiver chip and esd protector chip exist an device called " common mode choke "
from " common sense " >> without protection even factory service device can destroy the chips.
the choke is not mandatory device for usb link but elegant designers include one.
so stop spreading FUD
