Even though cell phones have dramatically changed since the 90s, loads of myths surrounding

The more megapixels the phone's camera has, the better images you get; the dimmer the

screen is, the better it's for your eyes; overnight charging harms the battery, smartphones

Smartphone myths are numerous and persistent.

So let’s pop some of these dubious bubbles, shall we?

Cell phones can start a fire at a gas station.

No one will argue that petroleum gas is highly flammable and can be started by a spark.

This spark can come from a lighter, matches, or static electricity - but not your smartphone.

The only way the device can start a fire is if it has a defective battery (which is pretty

There's no evidence of something like that ever happening.

Why cell phones are banned at gas stations is probably because they can and do distract

And being careless and inattentive while fueling your car can lead to serious accidents.

Charging a smartphone overnight damages the device.

There is a valid reason why your cell phone is called "smart."

Thanks to the built-in protection, it knows when it's supposed to stop charging.

And if a decade ago overcharging could indeed damage the battery, you don't need to worry

If you've dropped your smartphone in water, put it in rice.

Many people believe that the moisture-loving grains will absorb water out of all the nooks

But here's the problem: rice doesn't soak up just any liquid that happens to be nearby.

To absorb water, rice grains have to be in direct contact with it.

Even worse, when rice starch gets mixed with liquid, it produces a paste that can gum up

Experiments showed that after 48 hours, rice still managed to absorb only 13% of the moisture

By the time the devices got completely dry, corrosion had already damaged their fragile

So about the best you can get here is Smartphone Sushi, but I can’t imagine it tasting very

This myth became popular after a viral Internet article - lots of people believed that radio

waves a cell phone emits were so powerful that you could boil an egg by placing it between

Well, bad news for the lovers of unconventional cooking methods.

The amount of radiation a cell phone emits is so small that you would need 7,000 smartphones

to boil an egg - and even this number is very approximate since nobody has checked it yet.

A smartphone can demagnetize your credit cards.

"Never keep your phone together with your credit card!" - you've probably heard this

Your gadget does have a magnetic field, but it's so weak that it won't affect your bank

A fridge magnet, on the other hand, might cause your credit card to stop working!

Magnets can delete data from your smartphone.

If it's the most powerful magnet on Earth, probably.

Also, if you keep your info on floppy disks and tapes.

Magnets can do no permanent damage to your phone.

There are even several tiny magnets inside your smartphone used for specific functions.

Modern phones have solid-state drives that don't need magnetism for storing data.

What a magnet CAN do is interfere with your phone's compass.

You may say, "Ok, I don't need it anyway!"

But then your navigation apps, like GPS and all kinds of maps, won't be able to determine

your position, and game applications won't understand your phone's orientation.

Let your phone's battery drain completely before recharging.

One of the worst things you can do to your phone's battery is to keep draining it.

Every lithium-ion battery has a certain number of charge cycles (which is running the battery

Modern phone batteries have about 400 to 500 cycles.

And if you let your battery drain every day, your phone won't last longer than a year and

Some experts recommend draining your phone's battery completely only if your device quits

Then emptying the battery might help you recalibrate its level sensor.

The more megapixels your camera has, the better photos you'll get.

Most people are sure that the number of megapixels is the best indicator of how good your pictures

What they don't know is that not the number of megapixels but their quality plays the

A 12-megapixel camera can be way better than a 16-megapixel one.

High-quality pixels are also larger, and fewer of them have to be crammed into a single picture.

Since the 4G connection is faster, most people believe that it uses more data.

But whatever connection you use, 5 MB of data is still 5 MB of data.

With 4G, you'll just need less time to download it.

The only reason why 4G eats your Internet package too soon is that your downloads are

faster, and you use more data in a shorter period of time.

After all, it saves your battery, and that's a good thing, right?

If your smartphone's screen is too dim, you'll have to strain your eyes.

And even though it's unlikely to lead to any permanent damage, you'll get headaches and

If your screen brightness is higher than 50%, though, you should keep it down a bit.
