Many iPhone owners know the fear of seeing the “Low Battery” notification pop up on the screen.
But a tech expert has discovered a “hidden” setting that he claims could almost double the device’s lifespan.
Herby Jasmin, founder of tech site Gotechtor, said the trick is to adjust your phone’s “Reduce White Point” feature.
The feature creates a slight adjustment to the iPhone’s display that reduces glare and dims the brightest colors on the screen.
Users can find Reduce White Point in the Settings app on the iPhone’s iOS system.
A tech expert has recommended users turn on the white spot reduction feature on their iPhone to “double” battery life
“Since I changed this setting on my iPhone, I’ve noticed that my battery life has almost doubled compared to what it used to be,” Jasmin said in a mail.
The tech expert said he was playing around with the Settings app when he stumbled upon the ‘Reduce White Point’ option, which Adjusts the intensity of colors on the screen by dimming bright hues such as green, white, and yellow.
The phone automatically reduces bright colors, but users can manually dim them to further adjust the intensity.
Users need to go to the Display and Text Size option under the Accessibility section in Settings to access the Reduce White Point feature.
It can also be customized to activate during certain hours or when the sleep focus option is enabled.
But Jasmin said it will help conserve battery because the iPhone uses less power by not having to keep the screen as bright as it normally would.
Turning on the Reduce White Points feature can not only conserve your phone’s battery, but it can also have the added impact of reducing eye strain and fatigue.
When your phone’s colors are less vibrant, especially in darker environments like when you’re scrolling in bed, you help relieve eye strain and reduce the amount of sleep-disrupting blue light emitted.
“Most people use smartphones for shorter periods of time throughout the day, but can accumulate many hours of use by the end of the day,” according to KRAFF Ophthalmological Institute.
‘Although this is less stressful on your eyes, if you strain when looking at your mobile phone screen, it can mean you are putting stress on your eyes, leading to mobile phone eye strain. Over time, this can negatively affect your eye health.’
The advice comes at a time when Apple has faced criticism for its lithium-ion batteries that naturally degrade over time, reducing the charge a phone can hold to 80 percent.
Apple is preparing to unveil the new iPhone 16 next week, which is expected to offer better battery life and a more eye-pleasing organic light-emitting diode (OLED) display than previous organic light-emitting diode (LED) displays.
In her post, Jasmin suggested that those who don’t want to make the jump to the new iPhone should consider simply tweaking the white point feature for now.
