Maybe is the hardware Issue - Logic board damaged. You can analysis why your iPhone 6 won't charge as follows. Also you can go here to watch the video, including charing fault analysis and detail repair steps
Charging fault analysis

Connect ZXW to a computer, open PCB diagram software, Charging voltage input PP5V0_USB, battery voltage PP_BATT_VCC, Battery electric quantity detection BATTERY_SWI_CONN

Connect U1401, Tigris charger, USB control IC, overvoltage protection signal, U1700 damage can result in not charging, reboot and connect computer failure etc.

Charging fault detection

Open iPhone 6 screen, take down the screen, pull up the battery connector from logic board. The voltage is about 2.0V after measurement through stitch battery is ok.

Plug to charger, the voltage is 0.5V(normal 1.8V – 4.2V) after measurement through FPC connector, the logic board can’t charge.
