Sleep current: 6 µA. Sleep consumption over 3 years: 0.006 × 24 × 365 × 3 = 157.68 mAh.

Working scenario: wake‑up every 1 hour; each active duration 45 s; active current 50 mA.

Energy per wake‑up: (45 / 3600) × 50 = 0.625 mAh.

3‑year wake‑up‑mode consumption: 0.625 × 24 × 365 × 3 = 16425 mAh.

Total 3‑year consumption: 16425 + 157.68 = 16582.68 mAh.

Remaining capacity with 19000 mAh battery: 19000 − 16582.68 = 2417.32 mAh.

Additional motion‑triggered wake‑up count: 2417.32 ÷ 0.625 ≈ 3868 times.
