Should I Turn Off Auto-Brightness?

We generally don’t recommend turning off Auto-Brightness for two main reasons:

  1. You’ll have to manually adjust the brightness of your iPhone’s display any time it’s too bright or too dark.
  2. Your iPhone’s battery may drain more quickly if the display is set to a high brightness level for extended periods of time.
