Urgent warning for iPhone owners over common ‘vampire’ setting draining your battery – millions have never noticed it

IPHONE users have just been informed of a hidden setting that could be using up their device’s battery life.

Apple packs its iPhones with many user tools and features aimed at making your life easier.

One of these tools is called Wi-Fi Assist, which can help you stay connected to the Internet even if you have lagging Wi-Fi.

HOW DOES IT WORK?

Wi-Fi Assist automatically switches to cellular when you have a poor Wi-Fi connection.

Users tend to use it with apps like Safari, Apple Music, Mail, Maps, and more. 

“For example, if you’re using Safari with a poor Wi-Fi connection and a webpage doesn’t load, Wi-Fi Assist will activate and automatically switch to cellular so that the webpage continues to load,” Apple said on its website.

This can also be helpful if you’re streaming or downloading something and your Wi-Fi connection starts to slow down.

However, it can also eat up a lot of your cellular data if you’re not careful.

What’s more, it can deplete your iPhone’s battery life if it turns on often.

For those reasons, some experts have recommended that iPhone users turn this feature off.

HOW TO DISABLE WI-FI ASSIST

Apple revealed on its website that Wi-Fi Assist is on by default.

However, you can turn it off by heading to your device’s main Settings page.

From there, scroll down until you locate Cellular.

Then tap on Mobile Data and scroll down to toggle off Wi-Fi Assist.

Now that you’ve disabled Wi-Fi Assist, your iPhone will only use Wi-Fi when it has a strong connection.

Even if your Wi-Fi connection lags, your iPhone will not switch over to cellular data.
