From tonone-volt
Power management audit — analyze sleep modes, wake sources, power state machines, radio duty cycles, and battery life estimates. Use when asked to "audit power usage", "optimize battery life", "review power management", "why is my battery draining", "power budget analysis", or "sleep mode review".

Scan for power management code:
# Power management indicators
find . -name "*.c" -o -name "*.cpp" -o -name "*.h" -o -name "*.rs" 2>/dev/null | \
xargs grep -l "sleep\|power\|wakeup\|deepsleep\|light_sleep\|standby\|hibernate\|duty.cycle\|pm_" 2>/dev/null | head -20

Identify which sleep modes are configured and used:
| Sleep Mode | Platform Equivalent | Current Draw | Used? | Wake Sources |
|---|---|---|---|---|
| Deep sleep | ESP32: esp_deep_sleep_start() / Zephyr: pm_state_force(PM_STATE_SOFT_OFF) | µA range | [✓/✗] | [list] |
| Light sleep | ESP32: esp_light_sleep_start() / Zephyr: PM_STATE_SUSPEND_TO_IDLE | mA range | [✓/✗] | [list] |
| Modem sleep | Radio off, CPU on | reduced | [✓/✗] | [auto] |
| Active (no sleep) | CPU running, radios on | highest | N/A | N/A |
Flag if no sleep modes are used — that is the most common power bug.
For each radio in use (WiFi, BLE, LoRa, cellular):
Flag: always-on WiFi without modem sleep is the biggest power drain in most IoT devices.
Estimate the power budget for the main operating modes:
Mode | Current | Duration/Duty | Avg contribution
Active (MCU on) | [X] mA | [Y]% duty | [Z] mA
Radio TX | [X] mA | [Y]% duty | [Z] mA
Radio RX | [X] mA | [Y]% duty | [Z] mA
Deep sleep | [X] µA | [Y]% duty | [Z] µA
Peripherals | [X] mA | [Y]% duty | [Z] mA
─────────────────────────────────────────────────
Total average [Z] mA
Battery capacity: [mAh]
Estimated runtime: [hours / days]
If battery capacity and target runtime are known, flag if the budget exceeds the target.
| Check | Status | Note |
|---|---|---|
| Sleep mode implemented | [✓/✗] | |
| Wake sources correctly configured | [✓/✗] | |
| Peripheral power gating (disable unused) | [✓/✗] | |
| Radio duty cycle tuned | [✓/✗] | |
| Power state machine formally defined | [✓/✗] | |
| Wake-up time accounted for in latency budget | [✓/✗] | |
| Power consumption measured on hardware | [✓/✗] |

## Power Management Audit
**Platform:** [MCU] | **Target runtime:** [goal or unknown]
**Sleep modes used:** [list or NONE] | **Radio:** [always-on / duty-cycled / on-demand]
### Power Budget Estimate
Average current: [X] mA | Battery: [X] mAh | Estimated runtime: [X hours/days]
### Issues
- [RED] [critical power drain — e.g., no sleep mode, always-on radio]
- [YELLOW] [suboptimal — e.g., peripherals not power-gated, TX power too high]
- [GREEN] [good practice observed]
### Recommendations (Priority Order)
1. [fix] — [estimated current saving] — [effort: hours/days]
2. [fix] — [estimated current saving] — [effort: hours/days]
3. [fix] — [estimated current saving] — [effort: hours/days]
