5 common smartphone myths busted
We’ve all heard our fair share of tech tales over the years – but here’s the truth behind five of the biggest myths.

Of course, we all love a good story – but when it comes to what’s good and not so good for our phones we’ll take fact over fiction every time. Let’s put your mind at ease by debunking five of the most popular smartphone myths that have been circulating in the tech world for yonks.

Let your battery go down to 0% before recharging – MYTH

Who has the time to wait for their battery percentage to drop to zero before recharging? Luckily for you (and us), this couldn’t be further from the truth. The majority of smartphones these days come equipped with strong Lithium-ion batteries, which are more than capable of handling a full-ish charge at all times.


In fact, batteries are under the most strain when they’re fully charged or completely empty. Technically speaking, the real sweet spot for them is at around a 50 per cent charge. So, if you’re keen on keeping your battery living for as long as possible, you should try and keep it charged between 20 and 80%.

If you’re looking for a phone with a super strong battery, check out the Huawei P20 Pro at Carphone Warehouse.

More megapixels means better camera – MYTH

So you’ve finally chosen your new phone and you’re really impressed by the sound of the camera on it. After all, it’s got loads of megapixels. That’s good, right? Well, a bit but not entirely.


Sure, more megapixels do create images with a higher resolution but unless you’re zooming in or want to print out the image on a larger scale, you probably wouldn’t be able to tell the difference between 8MP and 12MP. When you’re choosing a camera, we’d recommend thinking about a large aperture, depth of field capabilities, wide-angle lenses and optical image stabilisation.

For a camera that covers all bases, take a look at the Google Pixel 3 at Carphone Warehouse.

Closing apps improves battery life – MYTH

It’s easy to see why we’d come to this assumption. After all, when you have loads of apps open on your laptop, it puts a real strain on the battery. But we’re pleased to tell you this isn’t the same with phones.


Apps don’t open in the same way on a laptop as they do on a phone. When you leave an app on your phone it actually freezes, stopping all function entirely. So closing them down does nothing for your battery whatsoever. But we understand that it’s nice to keep your phone tidy and organised though, so crack on.

Apps never looked better than on an amazing new iPhone Xr – available now at Carphone Warehouse.

4G uses up more data than 3G – MYTH

This one was even news to us tech heads. It’s true that 4G is much faster than 3G, but that doesn’t mean it uses more data. All apps and webpage downloads are the same size, no matter what network you’re on.

If you still have the sneakiny suspicion that 4G eats up more of your data than 3G, it could be because 4G lets you browse more pages in less time – meaning you could reach your data limit sooner. That 4G is just too fast for its own good.

And while we’re on the subject of speed – get the speed you need with the incredible Samsung Galaxy S9, available at Carphone Warehouse.

A phone could stop your credit card from working – MYTH

Rumour has it that keeping your phone in the same pocket as your credit card could damage its magnetic strip. There’s absolutely no truth in this. Cards are comprised of millions of microscopic magnetic particles, and while your smartphone is a powerful piece of tech, it wouldn’t give off enough power to affect a card’s strip.

You’ll actually do more damage to your card’s magnetic strip by exposing it to the strip on another card – so make sure you invest in a good wallet.

And as it’s perfectly safe to keep your card and phone in close proximity to each other, why not treat yourself to one of our handy wallet cases.

Those are our common smartphone myths you can stop believing. Have any more you want us to get to the bottom of? Ask away in the comments below.
