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

  • them are still the same!

  • 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

  • can float!

  • Nah, I made that one up.

  • Smartphone myths are numerous and persistent.

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

  • 1.

  • 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

  • much unlikely).

  • 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

  • drivers from the task at hand.

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

  • 2.

  • 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

  • about such an outcome these days.

  • 3.

  • 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

  • and crannies of their soaked phone.

  • 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

  • your smartphone's delicate electronics.

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

  • out of the phones.

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

  • electronic insides.

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

  • good!

  • 4.

  • Your phone can cook an egg.

  • 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

  • two devices.

  • 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.

  • 5.

  • A smartphone can demagnetize your credit cards.

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

  • recommendation, and not once.

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

  • cards in any way.

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

  • 6.

  • 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.

  • A modern-day smartphone?

  • Impossible.

  • 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.

  • 7.

  • 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

  • from 100 to 0%).

  • 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

  • a half.

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

  • working at 20% charge.

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

  • 8.

  • 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

  • are gonna be.

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

  • main role here.

  • 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.

  • 9.

  • 4G uses more data than 3G.

  • 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.

  • 10.

  • The dimmer the screen is, the better.

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

  • Well, your optician will disagree.

  • 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

  • tired eyes.

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

  • An over-bright screen can cause lots of short-term eye issues, from irritation to dry eyes and

  • strain.

  • 11.

  • Better specifications mean better performance.

  • While buying a brand-new phone, you expect to enjoy fast speed, long battery life, and

  • other perks.

  • But in reality, even if a phone has great specs on paper, its performance may be not

  • so satisfying, depending on its application compatibility, build quality, and other factors.

  • 12.

  • Smartphones emit harmful radiation.

  • Modern cell phones give off electromagnetic waves.

  • The same waves make your radio work.

  • The EM radiation frequency your smartphone emits is completely safe for you.

  • This fact has been proven by thousands of published articles, placing the topic of phone

  • radiation among the most researched.

  • 13.

  • If you make a call while your phone is charging, it may catch fire.

  • There have been several cases when devices started burning, but it happened because of

  • low-quality batteries, suspicious second-hand chargers, and dubious charging methods (for

  • example, trying to charge a phone from too-high-voltage lines).

  • If you have original batteries and chargers (in the way they should be used), you can

  • use a charging phone in any way you want, including making calls.

  • It'll just take longer for the phone to charge, that's all.

  • 14.

  • The larger your phone's battery capacity is, the longer it will serve.

  • The battery life mostly depends on how much power your device consumes.

  • That's why if you have two smartphones with the same battery capacity, the one with more

  • efficient electronics and screen will last longer on a single charge.

  • How you use your phone also influences battery life.

  • Playing games, taking photos, using social media drains your battery a mile a minute.

  • 15.

  • Close background apps to boost your phone's performance.

  • At first sight, it sounds very logical - the more apps your phone's running, the more battery

  • it's burning.

  • But in reality, both Android and iOS can multitask, and background apps aren't running, they're

  • just ready for a fast re-launch and don't consume a lot of energy.

  • By closing background applications, you waste more battery because your phone has to spend

  • more resources on opening an app than on re-launching it.

  • 16.

  • Using incognito mode will protect your privacy.

  • Privacy issues are on the rise these days.

  • It makes more and more people use the private or incognito mode while browsing the Internet

  • to keep their personal information safe.

  • It's believed to be a secure way to protect your data.

  • The private mode does prevent your browser from storing your cookies, passwords, and

  • other information.

  • But it doesn't equal an encrypted connection, and other people, for example, Internet service

  • providers, can see your browsing history.

  • Plus, no incognito mode will protect your device from malware.

  • For that, you need an antivirus.

  • Finally, if you like my Smartphone Sushi idea, tell me all about your recipes in the comments!

  • Hey, if you learned something new today, then give the video a like and share it with a

  • friend!

  • And here are some other videos I think you'll enjoy.
