Purpose: This tool diagnoses whether your charging problem is the port, cable, charger, or battery.
Most charging failures are caused by debris in the port, a damaged cable, or a worn battery β not necessarily a faulty port. A bent charging pin or loose connection is the most common true port fault.

π Book RepairYour result points to either a manageable issue you can address yourself, or a fault that needs professional attention before it gets worse.
Understanding why a problem happens helps you make better decisions β and helps us fix it faster.
The most common cause β bent pins, broken solder joints from repeated plug/unplug cycles or a dropped cable.
Pocket lint compacted inside USB-C or Lightning ports prevents the cable seating fully. Often mistaken for a hardware fault.
A fraying or internally broken cable is more often the issue than the port itself. Always test with a different cable first.
Windows or Android power management issues can prevent charging even when the hardware is fine. A driver reset often resolves this.
A more serious board-level fault where the chip managing power delivery fails β requires microsoldering to repair.
You can safely try: cleaning lint from the port with a wooden toothpick, testing with a different cable and charger, and trying a different power outlet. These rule out the most common non-hardware causes.
You need professional repair if: the port is physically loose, bent, or sparking; the device doesn't charge with any cable; or cleaning didn't help. Port replacement requires microsoldering on most modern devices β not a DIY job.
