In the fourth iOS 26.1 beta, Apple added a "Tinted" option that reduces the translucency of Liquid Glass for those who prefer a more opaque look.
A test was conducted to determine if the "Tinted" option preserves battery life, using an iPhone 17 Pro Max with the following settings: Light mode, True Tone and Night Shift turned off, 50% brightness, and the display set not to turn off.
The test aimed to mimic real-world usage, with notifications turned on to reflect a typical day.
