A React-Native library to help you detect iOS's low power mode.

Manual installation

iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-low-power-mode and add RNLowPowerMode.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNLowPowerMode.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Usage

import RNLowPowerMode from 'react-native-low-power-mode';

...

componentWillMount() {
    RNLowPowerMode.isLowPowerModeEnabled().then(isLowPower => {
        this.setState({isLowPower});
    });

    RNLowPowerMode.setLowPowerModeListener((isLowPower) => {
        this.setState({isLowPower});
    });
}

componentWillUnmount() {
    RNLowPowerMode.removeLowPowerModeListener();
}

That's it, it's that easy.

Now that you know the device is in low power mode, scale back animations and try to do less processing.
