The Truth About Airplane Mode and 20 Myths About Your Phone

The Truth About Airplane Mode and 20 Myths About Your Phone

Once upon a time, in a little town, there
lived a boy who dried his mobile phone with a hair dryer and never put it in airplane
mode before take-off. People told him to stop, but he wouldn’t
listen. So the passengers duck-taped him to the wing
outside, and he had a very windy flight, and lousy reception. Okay maybe not the duck tape thing. But let’s check out some common beliefs
about smartphones, and see if they’re appropriate or bogus.. 1. Drain your battery completely before you recharge
it. False. Batteries used in phones about ten years ago
really lasted longer if you dropped them to zero before plugging in the phone. Lithium-ion batteries used these days prefer
going at somewhere between 40 % and 80 %. If you often let it drain completely before charging
it again be prepared to replace the battery every six months or so. 2. Your phone is safe without a screen protector. True. First generation touchscreen smartphones needed
outside protection from scratches, chips and cracks. Today, phone screens are strong enough on
their own. The two things they can’t stand are sand and
hard rocks. So, unless you spend a lot of time at the
beach or drop your phone on concrete every now and then, you are good to go without a
screen protector. 3. You can dry a wet phone with a hair dryer. False and risky! Technically, you can dry your phone with a
hairdryer. But you don’t really want to because it
will overheat your gadget. Phones don’t like too much heat, just saying. I wonder if there’s some other way to solve
the issue. Rice maybe? 4. If hairdryer is too hot, just drop the phone
in a bag of rice. False. Unless you have a water-resistant device,
don’t drop into a bathtub, even if you always have a bag of uncooked rice on hand. Rice can absorb moisture, but not from the
inside of your phone. And, what’s worse, the starch off the rice
can get into the cracks and take the damage to the next level. 5. Charging overnight is bad for your phone. False. The first cell phones actually didn’t like
being charged overnight. But fortunately they really got smarter over
time. Today’s generation has extra protection
on the chips and in the software that won’t let them charge over 100 %. When they reach
that point, the process will just stop automatically. 6. Closing background apps is a sure way to save
battery. False. When you leave one app and start using a different
one, the first one is stored in RAM to reopen in exactly the same condition you left it. This multitasking algorithm helps save power. And, when you manually shut down apps that
aren’t in use, you’re wasting way more power. 7. The more megapixels, the better the photos. False. How many megapixels does your phone camera
have? One of my friends recently boasted of 48 MP. But looking at his pictures, I could tell
my 12 MP one is doing a better job at photography. The reason is, it’s quality and not quantity
of those megapixels that matters in the first place. When manufacturers squeeze more of those into
a phone cam, the sensor simply can’t handle them anyway. 8. Don’t keep your phone next to a credit card. … or else it will shop online and spend
all your money. Just kidding. This is also false: the myth goes that the
card will demagnetize if you keep it close to a smartphone. In truth, your smartphone’s magnetic field
isn’t nearly strong enough for that. A fridge magnet — maybe, but not the phone. 9. Using free public Wi-Fi is a chancy business. True. It’s a savior on vacation when data roaming
is crazy expensive and you don’t want to buy a local SIM. But that’s probably the only situation you
can really use it, and still with precaution and a VPN. Don’t ever pass on your personal data or financial
details when using a free grid. That’s because they are open to anyone, including
hackers that jump into communications to steal data. Wi-Fi hotspots are the worst in this regard
because they need no authentication for connection. 10. 4G eats more data than 3G. False. 4G just loads the same data volumes faster
than 3G. It does use slightly more battery power though. The same is true for 5G. So if you need to save battery, you might
wanna keep it on 3G unless you have to download something quicker. 11. A fast charger can damage your phone. False. Fast chargers send more electricity to your
phone and so it’s full of juice again in half the regular time or even quicker. Someone started a rumor that it can damage
the battery. In fact, a fast charger slows down somewhere
between 60 and 80 percent and then finishes the process at regular speed, so there won’t
be too much current. The only concern could be the extra heat,
but any battery ages with time anyway. 12. The more RAM, the better the phone is. False. Do you often have to work in 5 apps on your
phone at the same time? Unless you said yes, you don’t really need
to invest in a phone with 8GB RAM (that’s random access memory, just to make it clear),
because that’s what it’s much better at. A phone with 4 or even 3 GB with a powerful
processor works fast enough to let you switch from app to app and do other things. And, it’s just as fit for the latest operating
systems. 13. 4K display is what you absolutely need on
your phone. False. 4K is great for a large display, such as TV
or computer screen. As for your phone, it’s a waste of money. The human eye can’t perceive anything higher
than 2K or even Full HD on such a small display. More than that, the more pixels your phone’s
hardware has to drive, the more battery it spends on it. 14. Smartphones are a source of radiation. This is true, but it’s a kind of electromagnetic
radiation that is completely safe for humans. And no, you can’t cook an egg between two
ringing phones – that’s just an urban myth. You’d need about 7,000 phones to just warm
up the egg a tiny bit. By the way, if you steal the egg, you could
say it was “poached”.. ha 15. You can’t use your smartphone when it’s charging. False! It’s totally safe to do it. One thing you should know though, is that
it slows down the charging process. Do you personally use your phone while charging
or did you have doubts about the safety of this ritual? Let me know in the comments below. Speaking of charging… 16. Phones charge faster in airplane mode. Partly true. When you switch to airplane mode, your phone
stops trying to connect to cell towers and pinpoint your position. When these functions are disabled, it’s using
less energy. It does speed up the charging process, but
not that much. You might be able to save about 10 minutes,
but that’s it. 17. Your gadget can really interfere with plane
systems. This is easily one of the most burning issues
frequent flyers ponder on. And it’s true! Just one smartphone won’t mess up the flight. But if many passengers decide to ignore the
“please switch your devices to airplane mode” command, it can seriously interfere
with a plane’s flight systems. So you’d better not take that risk. 18. If you take out your SIM card, no one will
ever find you. False. If you think someone might ever want to track
your location, they’ll be able to do it even if you take the SIM card out. The trick might work in spy movies, but in
reality you can be easily found thanks to GPS as long as you’re still using that phone. 19. Plastic-based smartphones are the worst. False. They have their pros and cons, but all in
all they are just as good as metal or glass-based phones. And they even have some benefits: they are
cheaper, lighter, and highly unlikely to break even if you drop them. Plus, the plastic body makes signal reception
easier. 20. The only safe charger is the original one. Manufacturers want you to believe it, but
it’s actually false. Unless you go for a one-dollar knock-off,
quality third party chargers and cables are totally safe for your smartphone. They have built-in safety mechanisms just
like the original chargers and your phone won’t burn or anything. 21. Automatic brightness mode is a sure way to
save battery. Dimming your screen does help save some charge. But that whole automatic brightness mode is
brought to you by a light sensor that’s probably going to spend even more power on
collecting and analyzing data about the surroundings to pick the right light level. Hey, if you learned something new today, then

  1. I used to charge my phone but my parents said while playing and charging your phone at the same time the fuse will cut out and can damage your phone,..

  2. When i was a kid my mother gave me a phone then i realized theirs a airplane mode i thought it can fly so i turn it on and threw of the building i thought it will fly like an airplane.

  3. Why is it you put a video out a couple months ago that says do not let your phone charge overnight because it might damage the battery & now your saying it's o.k.?

  4. You cant use a hair dryer to dry your phone

    Yea ok

    My dad:*Uses hairdryer to dry his samsung galaxy 10 and dries my LG phone with a hairdryer cause our phones was wet in a swimming pool*

  5. So basically,I was on Holiday at spain.And The lady gave us the card to get in the apartment.Then,One Night My mum Put her Phone Next to The Card And The Next day we were waiting for my sister to go get her bag and then the card Didnt work The Phone drained all of it.Then we needed a new card.Lesson Learned!

  6. You're good to go without a screen protector. Until you realize your screen is scratched and fixing it costs more than changing a screen protector.
    If you don't use an app often, it is better not to run it in the background. It is stored in RAM. RAM only keeps data as long as it's fed with….you guessed it: electricity. Also, an app in the background DOES use CPU cycles regularly, which increases power consumption. Sometimes those cycles are used to connect the app to the network and download small amounts of data, which also affects battery life. Unless you use an app frequently, it is better not to have it running in the background.
    Check your facts.
    Also, a pixel is a pixel. It's not just megapixels that make a picture better, but the more pixels a picture has, the higher the chance of getting more crisp details. Lens have to do with it, focal length and other processing algorithms have an impact as well. 48 MP are actually 12 MP with a technique that multiplies a pixel by 4. That's why a 12MP picture seemed to be better than a 48MP one.
    48 actual MPs will provide more detail than 12MPs. No such thing as the "quality of a pixel".

    More RAM is better – but up to a point. Just because the CPU works fast enough, doesn't mean the app actually retains its state. So when the app gets dropped from the RAM, the next time you fire it up the content will either have to be re-updated or you won't have the previous state saved so everything has to be reloaded – which involves locating executables in the flash memory (NAND), executing the code to get it back into RAM and loading any additional data. That takes time, so your CPU will have to work faster to compensate. More RAM does improve phone performance by keeping even not so often used apps in the RAM and available. Again, you make general statements without knowing what you're talking about.

    NOBODY in their right mind thinks "4K display is what you absolutely need". Stop making up facts.
    Smartphones don't interfere with plane systems as much as they used to. Remember they provide internet connectivity on the plane itself. That generates signal strong enough for multiple passengers to use the internet. Again, get your facts right. You CAN use your smartphone while on the plane because plane systems use different frequencies to operate than the ones used by the smartphone's antennas.

  7. 4:26 oh here we go again another bogus claim from a vpn. ITS FINE

    Password theft used to be an issue, someone could run an arp spoofing attack (aka man in the middle attack) and steal ur passwords. Nowadays every website and service with a padlock in the browser is encrypting your data anyway. So is every app released after 2017. The vpn companies dont tell you this otherwise there's no point in you buying their service 😉
