There’s a lot of misinformation out there about cellphones, and it’s easy to get sucked into believing the wrong things. But if you want to know the facts about cellphones, then this is the post for you. Here we’re going to bust 10 common cellphone myths, and explain why they’re simply not true.
Myth #1: Overnight Charging Damages Your Phone
Charging your phone overnight is a common practice for people who use their phone as a flashlight, alarm clock, or other device that requires a battery. The reason charging your phone overnight does not damage your phone is because the charging circuit inside the phone is designed to prevent over-charging.
When the battery is full, it will stop charging. As soon as your phone stops drawing energy from the battery, the charging circuit inside your phone turns off. This means that your phone will not be able to draw any more energy from the battery.
Myth #2: Automatic Brightness Saves Battery Power
Automatic brightness setting is supposed to save you batttery juice. But that’s not always the case. One reason is that the light sensor that detects the level of light actually consumes a lot of battery power even if you’re in a dark area. Also, you are most likely to be in a well-lit room while using your phone.
Myth #: Closing Background Apps Will Save Battery Power
There are a lot of people who think that closing their apps is a way to conserve their battery power. However, this isn’t true at all. Closing your apps doesn’t save any battery power at all.
When you close an app, the app is simply moved off of the RAM or the disk. The RAM and the disk are the two main parts of the computer. The RAM is the memory space that the computer uses to hold the files and the data. The disk is the storage space that holds all of the data that’s being used by the computer.
So when you close an app, it just moves the app to the RAM. This means that the RAM is empty. When you open an app again, it needs to be loaded into the RAM. This process takes time and uses up more battery power.
Myth #4: The Higher Megapixels, The Better Picture Quality
Megapixel is a measure of how many pixels are on a camera’s sensor. The higher the megapixel count, the better the camera will be able to take pictures.
But, don’t get too excited about the megapixel count. It doesn’t guarantee better pictures.
A high-megapixel camera won’t necessarily take better pictures than a low-megapixel camera. The difference comes from the quality of the lens and the lighting in the environment where the photo is taken.
The quality of the lens is determined by the size of the aperture and the focal length. A larger aperture lets more light in and creates a sharper picture. The focal length is the distance between the lens and the sensor.
The higher the focal length, the closer the subject appears in the image. A longer focal length also makes the subject appear bigger.
When you take a photo, the camera uses a small aperture, which allows more light into the camera. This causes the subject to be out of focus.
If the lighting conditions are poor, the camera will use a wide-aperture lens, which will make the subject appear blurry.
To take a good picture, you need to take a photo with the right aperture and focal length. You can’t just snap a photo with a high-megapixel camera and expect it to turn out well.
A smartphone camera has a fixed aperture, so it’s not possible to change the size of the aperture to take better pictures.
So, if you want to take better pictures on your cellphone, you need to change the settings on the camera app.
The camera app is where you can change the settings for the photo. For example, you can adjust the exposure (how bright or dark the photo is), the white balance (the color temperature of the image), and the contrast (how much detail is in the image).
Myth #5: Free Wifi is Secure
If you’re using free WiFi at a coffee shop or airport, you may be exposing your device to potential hackers. Free WiFi is a great thing, but it comes with a price.
A hacker can gain access to your personal information if he or she gets close enough to your device. In the case of free WiFi, it’s pretty easy to do. A hacker can simply use the same login credentials as you. If they have your username and password, they can access your data.
The best way to avoid this from happening is to use strong passwords. Make sure they’re unique and long. The longer the password, the harder it is for a hacker to guess.
Also, don’t save your login credentials on your phone. Instead, keep them in a safe place and don’t forget them.
Myth #6: 4G Consumes More Bandwidth than 3G
4G is faster that 3G, no question about that. But remember that 1MB is 1MB whether it takes one minute or 10 minutes to download. The same thing will happen when 5G becomes more and more ubiquitous. 1MB is 1MB whatever the speed!
Myth #7: Cellphone Radiation Can Harm You
Cellphone radiation is not harmful to humans because it’s a low-frequency electromagnetic wave.
There are many different types of radio waves, and they all fall into one of three categories: high, medium, or low frequency. High-frequency waves include microwaves, which are used in cell phones, radar, and some satellite communications. Medium-frequency waves include FM radio, AM radio, and TV broadcasts. Low-frequency waves include the natural radio waves that we can hear with our ears, such as the static you may hear on your radio.
High-frequency waves have a short wavelength and a high frequency. These waves are very powerful and can penetrate deep inside the body. They can cause damage to cells and DNA, and this is why they are not good for us.
Medium-frequency waves have a longer wavelength and a lower frequency than high-frequency waves. They do not travel as far, but they still have the ability to penetrate through the skin. They can also cause damage to cells and DNA.
Low-frequency waves have a longer wavelength and a lower frequency than medium-frequency waves. They do not travel as far, but they can still penetrate through the skin. They do not have the same power as high-frequency waves, but they can still cause damage to cells and DNA.
Cellphone radiation is a low-frequency electromagnetic wave. It has a long wavelength and a low frequency. It does not travel as far as high-frequency waves, but it can still penetrate through the skin.
Because it is a low-frequency wave, cellphone radiation is not harmful to humans.
Myth #8: Don’t Put Your Cellphone Next to a Credit Card
You’ve probably heard well-meaning family or friends telling you not to put credit cards near a cellphone. Credit cards and debit cards have a magnetic band that keeps your information. They say that putting a cellphone near a credit card could damage that magnetic strip. That’s not true.
While cellphones do have a magnetic field, it’s not strong enough to damage your credit card or debit card. However, a bag’s magnetic clasp COULD damage your cards.
Myth #9: You Can’t Use Your Phone While Charging
You’d be happy to know that, yes, it’s okay to use your phone while it’s charging. Note that some other devices MUST NOT be used while charging. But for cellphones, it’s quite alright. The only downside is that it will take longer to a get full charge. Other than that, you’re fine.
Myth #10: You Can Fix a Wet Phone With a Hair Dryer
Sure, a hair dryer can dry your phone. At the same time, it could also damage the sensitive electronics inside your phone due to overheating. The best thing you can do if ever your phone gets wet is to take it to a technician who has the tools to safely disassemble your phone and dry it properly.
There you have it. Ten cellphone myths busted!
