But if you aren’t, then you'll see an extension to your battery life if you simply switch Wi-Fi and/or Bluetooth off. I know this recommendation doesn't apply if you are using Wi-Fi or Bluetooth to get things done. NB: In Settings>Display & Brightness you can disable Automatic appearance and True Tone and set the brightness levels down as low as possible in order to conserve battery life. If you are trying to extend battery life, even a 1% or 2% improvement means you’ll get more time between every charge. Recent tests suggest that there’s an appreciable difference in battery life if you use Dark Mode on your iPhone and with your apps. The downside: when your display is brighte,r you’ll be using more power to display what’s on it. The thing is, this also means your display will be brighter when used in bright places, such as when outside. When you use your iPhone, your display’s True Tone feature automatically adjusts display brightness to make colors appear consistent in different places.
NB: If the Battery icon does not appear in your Control Center, visit Settings>Control Center>Customize and enable Low Power Mode there. You can also enable Low Power Mode in Settings>Battery>Low Power Mode.
