# my.offMemoryWarning

> Stop listening for system memory warning events.

Use this API to stop listening for memory warning events that were registered with `my.onMemoryWarning()`.

## Parameters

| Property | Type     | Required | Description                                                             |
| -------- | -------- | -------- | ----------------------------------------------------------------------- |
| callback | Function | No       | The specific callback to remove. If omitted, all listeners are removed. |

## Code Example

### Remove All Listeners

```javascript theme={null}
// Remove all memory warning listeners
my.offMemoryWarning();
```

### Remove Specific Listener

```javascript theme={null}
Page({
  onLoad() {
    my.onMemoryWarning(this.handleMemoryWarning);
  },

  handleMemoryWarning(res) {
    console.log('Memory warning:', res.level);
    this.releaseResources();
  },

  onUnload() {
    my.offMemoryWarning(this.handleMemoryWarning);
  },

  releaseResources() {
    this.setData({ cachedImages: [] });
  }
});
```

### Conditional Memory Monitoring

```javascript theme={null}
Page({
  data: {
    monitoringMemory: false
  },

  startMemoryMonitoring() {
    my.onMemoryWarning(this.onMemoryWarning);
    this.setData({ monitoringMemory: true });
  },

  stopMemoryMonitoring() {
    my.offMemoryWarning(this.onMemoryWarning);
    this.setData({ monitoringMemory: false });
  },

  onMemoryWarning(res) {
    console.log('Memory level:', res.level);
  }
});
```

<Tip>
  Pass the same callback function reference to `my.offMemoryWarning()` that was used with `my.onMemoryWarning()` to remove only that specific listener.
