In the fourth iOS 26.1 beta, Apple added a "Tinted" option to reduce the translucency of Liquid Glass for a more opaque look.
To test whether this setting preserves battery life, four separate tests were conducted using the iPhone 17 Pro Max with similar parameters: Light mode, True Tone and Night Shift turned off, 50% brightness, and the display set not to turn off.
No specific results were mentioned in the provided text.
