Many iPhone owners know the feeling of dread when they see a ‘low battery’ notification flash on the screen.

Considering how addicted to our phones we are, losing power means losing our connection to the world. 

But a tech enthusiast has shared a ‘fool-proof’ trick that gives devices ‘unlimited power.’ 

The hack will be welcome news for those who updated their iPhones to iOS 17.1.1 last week only to join the chorus of complaints that the new software has ruined their battery life, with some reports of charges draining in just a few hours.

It takes a short trip to your iPhone’s Settings to get your battery back on track. 

The hack, which comes from a TikTok user who posts under the @T_Sply, promises ‘unlimited cell phone battery’ just by selectively dimming your screen.

Once in your iPhone’s Settings, click from Accessibility to Display & Text Size and switch on the Reduce White Point option.

The more concerned you are about conserving your battery life, the further you should push your slider, reducing the whites on your screen as far as it will go.

Scientists at Cambridge University are working on a microchip that could run so efficiently devices could only need to be charged only 12 times a year. 

While the hack might lead to trouble for those using their phone in bright, sunny outdoor settings, for most iPhone users, reducing the white point will have the added benefit of reducing eye strain or helping negotiate ‘screen time’ before bed. 

Doctors say that melatonin levels usually start to rise at about 9pm, increasing through the night and peaking in the early morning hours.

By 9.30 PM each night, the pineal gland in your brain will typically be cranking out melatonin, preparing your brain for sleep. 

Very bright lights, including those from all the social media scrolling on your phone in the evening, can disrupt this process. 

True: some users might find this hack makes it harder for them to read messages and other text on their phone — but fortunately, there’s a solution there, too. 

Reduce White Point is not the same as adjusting Brightness on your iPhone’s home screen, which means you can tweak both to find the sweet spot that maximizes your own phone’s readability and the battery power sucked up by lighting your screen. 

Swipe down from the top of your screen and increase the brightness level, using the sun icon on the home screen.
