The Truth About Airplane Mode and 20 Myths About Your Phone

Once upon a time, in a small town, there was a boy who dried his mobile

phone

with a hair dryer and never put it on

airplane

mode

before taking off. People told him to stop, but he didn't listen. So the passengers taped him to the outer wing, and he had a very windy flight with lousy reception. Well, maybe it's not the duct tape thing. But let's review some common beliefs about smart

phone

s and see if they are appropriate or false. 1. Drain the battery completely before recharging. FAKE. Batteries used in phones about ten years ago actually lasted longer if you left them at zero before plugging in the phone.

Lithium-ion batteries used today prefer to use between 40% and 80%. If you often let it drain completely before charging it again, be prepared to replace the battery about every six months. 2. Your phone is safe without a screen protector. TRUE. First-generation touchscreen smartphones needed exterior protection from scratches, chips, and cracks. Nowadays, 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 from time to time, you can 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 hair dryer. But you really don't want to do that because it will overheat your device. Phones don't like the heat too much, just saying. I'm wondering if there is any other way to solve the problem. Rice maybe? 4. If the hair dryer is too hot, simply drop the phone into a bag of rice. FAKE. Unless you have a waterproof device, don't get in the bathtub, even if you always have a bag of raw rice on hand. Rice can absorb moisture, but not from the inside of your phone.

And even worse, the starch in rice can get into the cracks and take the damage to the next level. 5. Charging overnight is bad for your phone. FAKE. The first mobile phones did not like to be charged overnight. But fortunately they became smarter over time. The current generation has additional protection on the chips and software that does not allow them to charge more than 100%. When they reach that point, the process will automatically stop. 6. Closing background apps is a sure way to save battery. FAKE. When you leave an application and start using a different one, the first one is stored in RAM to be reopened in exactly the same conditions in which you left it.

This multitasking algorithm helps save energy. And, when you manually close apps that aren't in use, you're wasting a lot more energy. 7. The more megapixels, the better the photos will be. FAKE. How many megapixels does your phone's camera have? One of my friends recently boasted about 48 MP. But when looking at the pictures of it, I realized that my 12 MP camera is doing a better job at photography. The reason is that, first of all, what matters is the quality and not the quantity of those megapixels. When manufacturers cram more of these into a phone's camera, the sensor simply can't handle them anyway. 8.

Don't leave your phone next to a credit card. …or you will shop online and spend all your money. It's a joke. This is also false: there is a myth that the card becomes demagnetized if you keep it near a smartphone. In

truth

, the magnetic field of your smartphone is not strong enough for that. A fridge magnet... maybe, but not the phone. 9. Using free public Wi-Fi is risky business. TRUE. It's a savior on vacation when data roaming is very expensive and you don't want to buy a local SIM card. But that's probably the only situation where you can really use it, and even with caution and a VPN.

Never transmit your personal or financial data when using a free network. This is because they are open to anyone, including hackers who tap into communications to steal data. Wi-Fi hotspots are the worst in this regard because they don't require authentication to connect. 10. 4G consumes more data than 3G. FAKE. 4G simply loads the same volumes of data faster than 3G. However, it consumes a little more battery. The same goes for 5G. So if you need to save battery, you might want to keep it on 3G unless you need to download something faster. 11. A fast charger can damage your phone.

FAKE. Fast chargers send more electricity to your phone and therefore it is back to full power in half the normal time or even faster. Someone started a rumor that it can damage the battery. In fact, a fast charger slows down by 60 to 80 percent and then finishes the process at normal speed, so there won't be too much current. The only concern might be the extra heat, but the battery ages over time anyway. 12. The more RAM, the better the phone will be. FAKE. Do you often have to work on 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 of RAM (that's random access memory, just to be clear), because that's what it's much better at.

A 4 or even 3GB phone with a powerful processor runs fast enough to let you switch from one app to another and do other things. And it's just as suitable for the latest operating systems. 13. The 4K screen is what you absolutely need in your phone. FAKE. 4K is ideal for a large screen, such as a television or computer screen. As for your phone, it's a waste of money. The human eye cannot perceive anything higher than 2K or even Full HD on such a small screen. More than that, the more pixels your phone's hardware has to handle, the more battery it will drain. 14.

Smartphones are a source of radiation. This is true, but it is a type 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. It would take about 7,000 phones to heat the egg a little. By the way, if you steal the egg, you could say it was “poached”.. ha 15. You can't use your smartphone while it's charging. FAKE! It is totally safe to do so. However, one thing you should know is that it slows down the charging process. Do you personally use your phone while charging it or did you have questions about the safety of this ritual?

Let me know below in the comments. Speaking of charging… 16. Phones charge faster in

airplane

mode

. Partially true. When you switch to airplane mode, your phone stops trying to connect to cell towers and determine your position. When these features are disabled, less power is used. It speeds up the charging process, but not that much. You might be able to save about 10 minutes, but that's it. 17. Your device can actually interfere with the plane's systems. This is easily one of the hottest topics frequent travelers ponder. And it's true! A single smartphone won't ruin the flight. But if many passengers decide to ignore the command "switch your devices to airplane mode," it can seriously interfere with a plane's flight systems.

So you better not take that risk. 18. If you take out your SIM card, no one will ever find you. FAKE. If you think someone will ever want to track your location, they will be able to do so even if you remove the SIM card. The trick may work in spy movies, but in reality you can be easily found thanks to GPS as long as you continue using that phone. 19. Plastic smartphones are the worst. FAKE. They have their pros and cons, but overall they are just as good as metal or glass phones. And they even have some advantages: they are cheaper, lighter, and very unlikely to break even if dropped.

In addition, the plastic body makes it easier to receive the signal. 20. The only safe charger is the original one. The manufacturers want you to believe it, but it is actually false. Unless you opt for a dollar knockoff, quality third-party chargers and cables are totally safe for your smartphone. They have built-in safety mechanisms like the original chargers and your phone won't burn up or anything like that. 21. Auto-brightness mode is a sure way to save battery. Dimming the screen helps save some power. But all that auto-brightness mode is delivered by a light sensor that will likely spend even more energy collecting and analyzing data about the environment to choose the right light level.
