Test matrix

What to test and what a pass actually tells you

Run the test closest to the symptom. A passing result narrows the diagnosis; it does not certify the entire device.

Battery Runtime CalculatorEstimate runtime from battery watt-hours, average load and conversion efficiency.

Use the result to narrow the next branch; browser visibility is intentionally limited to the subsystem exposed by the current API.

→
Video File Size CalculatorEstimate video file size from average bitrate and recording duration.

Use the result to narrow the next branch; browser visibility is intentionally limited to the subsystem exposed by the current API.

→
SD Card Video Recording Time CalculatorEstimate how long a memory card or drive can record at an entered average video bitrate.

Use the result to narrow the next branch; browser visibility is intentionally limited to the subsystem exposed by the current API.

→
Data Transfer Time CalculatorEstimate ideal transfer time from data size and an entered link rate.

Use the result to narrow the next branch; browser visibility is intentionally limited to the subsystem exposed by the current API.

→
Gamepad Controller TestTest browser-detected controller buttons and analog axes.

A pass proves browser input events are arriving; app/game mappings, profiles and accessibility settings move higher on the list.

Problems worth separating on this model

01 · Media storage planningReproduce this symptom independently, then choose the closest live test or exact compatibility record before changing drivers, firmware, cables or hardware.
02 · Controller/browser input comparisonReproduce this symptom independently, then choose the closest live test or exact compatibility record before changing drivers, firmware, cables or hardware.
03 · Battery/runtime planningReproduce this symptom independently, then choose the closest live test or exact compatibility record before changing drivers, firmware, cables or hardware.
04 · Transfer workflowReproduce this symptom independently, then choose the closest live test or exact compatibility record before changing drivers, firmware, cables or hardware.
05 · Flight-control or sensor problem requiring DJI Fly/supportReproduce this symptom independently, then choose the closest live test or exact compatibility record before changing drivers, firmware, cables or hardware.

Evidence handoff

If the browser cannot reach the suspected subsystem

Keep the browser result as one observation, then move to the operating system or manufacturer diagnostic that can see the protected hardware state. Do not interpret an unsupported browser API as a failed component.
