What is the smart battery‑saving mode on the LARK A2?

After enabling the Smart Battery‑Saver feature, the Mic indicator light will illuminate for 6 seconds only when you press a button or start/stop recording, then automatically turn off. When connected to your phone and not in recording mode, the microphone enters low‑power standby; with this feature enabled throughout, you can expect an additional 1.5–2 hours of battery life.
