PowerScope
A power-profiling extension for VS Code that turns a bare current trace into a ranked, per-event power breakdown. Same shift a CPU profiler made for performance debugging, now for battery life.

What PowerScope Will Do
Turns power debugging into profiling, not guessing
A raw current trace can't tell you which advertising or connection event caused a spike, so most teams eyeball an average and call it done. PowerScope decodes what your radio was doing and stamps it onto the trace automatically — TX, connection events, retries, sleep — so you get a ranked breakdown of where your power budget actually goes.
Catches what averages hide
A fuel-gauge percentage or an average current reading can't show that one event type spikes hard above baseline — the kind of thing that quietly drains a coin cell to brown-out at end-of-life while the average still looks fine. PowerScope's per-event breakdown makes that event visible at the bench, before it's a field complaint.
- Captures power with the Nordic PPK2 or a Joulescope — no new hardware to buy
- Runs inside VS Code, where you already write firmware
