🔧 Xiaomi Redmi 9T Charging Ways & Jumper Solution – Full Repair Guide
This guide explains how to diagnose the issue step by step and how to apply a safe and effective jumper solution to restore proper charging functionality.🛠️ Understanding the Charging Line Path – Where Faults Commonly Occur
The Redmi 9T uses a dual-board design with a lower charging sub-board connected to the main motherboard through a flex cable. To identify the exact fault, technicians should follow a systematic approach:
1. Inspect the USB-C Charging Port
Start with the basics:- Check for dust, oxidation, or corrosion
- Look for bent or damaged pins
- Test reaction when connecting a known-good charger
2. Test the Charging Sub-Board
The bottom sub-board handles:- USB-C input
- Microphone
- Initial charging circuitry
3. Check the Interconnect Flex Cable
In many Redmi 9T cases—including the fault discussed here—the issue is caused by a broken or weak charging line inside the flex cable that connects both boards.
