Diagnosing before replacing

  • DC power supply: powers a board without a battery and shows current draw, which reveals shorts and boot loops.

  • Thermal camera: finds the hot component on a shorted rail in seconds.

  • Boot cables and test fixtures: power phones or test boards outside the housing.

  • Programmers: read and write battery, True Tone and Face ID data.

FAQ

What is the first tool for diagnosing a dead phone?

A DC power supply with a boot cable – the current draw pattern shows whether the board is shorted, not booting or stuck.

How do I find a short on a motherboard?

Inject a low voltage into the shorted rail with a DC power supply and look for the component that heats up, using a thermal camera or freeze spray.

What does a programmer do?

Programmers read and write data stored on chips, such as battery health data or screen True Tone data, so it can be transferred to a replacement part.
