Fix Pluely v1 High CPU Usage or Battery Drain

Noticing your fan spin up, your laptop battery drop faster than usual, or Task Manager/Activity Monitor showing Pluely v1 using a lot of CPU? This is almost always tied directly to active transcription — audio capture and realtime processing are genuinely CPU-intensive work, and that usage should drop sharply once a Listen session ends. Here's how to confirm that and reduce unnecessary load.

Why this happens

Listen mode continuously captures and streams two audio sources (your microphone and system audio) and processes them for realtime transcription. This is inherently more resource-intensive than Pluely's idle state, where the overlay is just sitting quietly waiting for input. If CPU or battery usage is high specifically while Listen mode is active, that's expected — the important question is whether usage returns to normal once you stop it.

1. Close Listen mode when you're not actively using it

The single biggest thing you can do is make sure you're not leaving a Listen session running longer than you need it.

1. Press Stop explicitly when a meeting or conversation ends, rather than just switching away or minimizing the overlay.
2. Confirm the session actually stopped — the overlay or tray icon should reflect an idle state.
3. Avoid starting Listen mode "just in case" for long stretches where you're not actually needing live transcription.

2. Check whether usage returns to normal when idle

1. Stop any active Listen session.
2. Wait a minute, then check CPU usage for Pluely in Activity Monitor (macOS), Task Manager (Windows), or your system monitor (Linux).
3. If usage drops back down to a small background footprint, this confirms the load was tied to active transcription, which is expected behavior, not a bug.

3. Update to the latest Pluely v1

Performance and efficiency improvements ship regularly. If you're on an older build and see unusually high usage even at idle, update from Installation and re-check.

4. Avoid running redundant sessions or overlapping features

Running push-to-talk and Listen mode together unnecessarily, or leaving multiple Pluely windows/instances open, can compound resource usage. Stick to one active capture mode at a time for the lightest footprint — see Listen mode for how it's meant to be used.

5. Consider your machine's baseline performance

Older or lower-powered machines will naturally show a bigger relative impact from any CPU-intensive task, including live audio transcription. If Pluely's idle usage (with no active session) is low and only spikes during Listen mode, that's expected scaling with your hardware rather than an issue specific to Pluely.

6. Battery-specific tips on laptops

• Keep your OS and drivers up to date, since audio driver inefficiencies can amplify power draw during any audio-heavy task.
• Use push-to-talk instead of continuous Listen mode when you only need occasional questions answered, since it avoids continuous audio streaming.
• Plug in during long meetings you plan to transcribe, the same way you would for any other video call software.
