OBJECTIVE

Test cables and adapters systematically so charging capability is not confused with data or display support.

TIME PLAN

Prepare 20m · Build 110m · Verify 30m · Document 20m

Working boundary

Work only inside the folder created by Smartphone-Academy.py prepare usb-c-data-power-validation. Use the supplied samples, your own phone, or systems you are explicitly authorized to administer.

Prepare the Termux workspace

Open Termux in the Academy root and prepare this lab with the local companion. It creates safe samples, notes and evidence files under your Termux account.

Android + Termuxpython Smartphone-Academy.py prepare usb-c-data-power-validationNo root. Keep the workspace under $HOME and avoid personal identifiers in evidence.

Practical mission

  1. Label each cable, charger, adapter and test device without relying on appearance
  2. Test charging, data transfer, OTG and any supported video mode separately
  3. Record negotiated behavior and failures without exceeding rated limits
  4. Create purchase and troubleshooting guidance from verified results
EVIDENCE TO PRODUCE

A USB-C capability matrix with tested combinations and clear uncertainty labels.

Quality gate

The scope, date and tested device or workspace are clearly identified.
Every conclusion points to a command result, setting, source or measured observation.
Another learner can repeat the procedure without guessing hidden steps.
Limitations, uncertainty and any skipped checks are recorded honestly.

Analyst reflection

Which result from “Create purchase and troubleshooting guidance from verified results” needs stronger evidence before it can support a real decision?

Complete in Termux

After checking the evidence, run python Smartphone-Academy.py complete usb-c-data-power-validation. Progress is stored locally in the Termux home directory.
