Every week, 5-10 customers blame device when culprit is cable.

Top failures:

• Internal shield break near connector strain relief, intermittent
• GND wire frayed, charges slow or device says 'not authentic'
• Cheap charging-only cable used for data, customer thinks USB port broken
• Counterfeit Type-C, missing CC resistors, fast-charge fails

Shop trick: keep one 'known good' Type-C, Type-B, Micro on workbench. First diag step swap cable. Saves hours.

Buying cables? Pay PHP 150-300 for branded, skip the PHP 50 ones for anything you care about.
