Fool-proof iPhone setting that makes battery 'unlimited'

A man has claimed he has found that tweaking an iPhone setting will give you 'unlimited' battery life.

TikTok star Marcus Obeada says his clever hack means you will 'never run out' of juice.

Many iPhone users complain that their devices just don't last as long as they used to, so this could solve their battery problems.

Marcus seemed to have stumbled across the supposed solution while browsing through his phone settings and decided to share it with the rest of the world.

On his TikTok account @t_sply, he posted a step-by-step guide to achieving 'unlimited cell phone battery'.

First, simply head to your iPhone's Settings, click on 'Accessibility' and then onto 'Display & Text Size'.

Scroll down to find the 'Reduce White Point' toggle, which will lessen the intensity of bright colours on your screen.

A slider will then appear - and according to Marcus, the more battery you want to save, the higher the percentage you drag it to.

His screen immediately becomes visibly dimmer and he even went onto then reduce his brightness to the lowest setting.

It may save him some battery, but he will certainly need to squint to read his messages.

Utilising this setting when you're winding down for the night is also useful, as it helps your eyes adjust to the darkness.

It also works for people who are just not a fan of the vibrancy of their phone screens when its 'White Point' is at full throttle.

Some social media users were appreciative of Marcus' tech advice, but others said he shouldn't have bothered.

One wrote: "I did it and now I can't see anything."

Another said: "What's the point? Then my phone is useless. Just like telling me not to use my phone, no battery will be wasted as well."

A third added: "Well, I mean now I know how to use my phone at night if it's still too bright for my eyes."

Some commented that they 'loved' the tech tip, but a few people questioned whether it was even effective at all.

One person claimed: "This adjusts the colours of your screen, not the brightness. Therefore, it has no impact on battery life."

Apple is currently facing a UK lawsuit that could force them to cough up some compensation due to its allegedly defective iPhone batteries.

Consumer champion Justin Gutmann launched the class action on behalf of about 24 million people, accusing the tech giant of 'throttling' customers' gadgets without their knowledge.

Apple allegedly concealed issues with the batteries of several iPhone models; the iPhone 6, 6 Plus, 6S, 6S Plus, SE, 7, and 7 Plus.
