Top Tech Myths/Misconception 

Technology is evolving at the speed of light. You blink your eye and you miss the latest development in tech. With technology advancing so fast, there are still some misconceptions/myths that need to be cleared. In this article, we will try to clear some of the most common misconceptions that people have about tech.

1. More Megapixel means a better camera.

This is the most common misconception that I personally have come across. While purchasing a smartphone or a camera, people always take a look at the number of megapixels to judge its camera quality. Well, megapixels are not all that decides the end image quality. An image sensor, aperture, post image processing etc are few things on which the final image quality depends. If you take a look at Apple smartphones, they never have large Megapixels but their image quality is always better than most of the Android smartphones in the market.


2. You shouldn’t charge your phone overnight.

This is true to some extent but doing so will not cause much damage to your batteries. The damage caused will be noticeable after few years of usage and most of us don’t use our phone for more than 2 years. To avoid the damage use a charger which charges your phone at a slower speed than normal.

3. Mobile phone signals can cause cancer

Mobile phones emit radiofrequency energy from their antennas and our body tissues nearest to the cell phone can absorb this energy. Ionizing and non-ionizing radiations are the two types of electromagnetic energy. The radiations emitted from our phones are of the non-ionization type, which is present in extremely low frequency. The dose of the absorbed energy is estimated using a measure called the specific absorption rate (SAR). Every phone goes through a series of tests at FCC where their SAR value is checked before sale. FCC certifies only those phones which have SAR value below the specified limit. Every country has a different SAR value limit. SAR value limit for USA and Canada is 1.6 watts per kilogram (w/kg) while for European nations and India it goes up to 2.0 w/kg which is very less to cause damage to human DNA. You can check your phone’s SAR value by typing *#07# in your dialer.


4. You can’t recover files once they have been deleted from the Recycle Bin.

At some point in your life, you might have accidentally deleted important files from your computer and scratched your head thinking that these files cannot be recovered. Well, you are wrong. The files deleted from the recycle bin can be recovered using various softwares that are available online. NTFS and FAT32 are the two most common file systems used by Windows. Files deleted on Windows are recoverable easily. The HFS on MacOS is the most difficult file system which is a little difficult to recover. Many online blogs have listed Recuva as the top data recovery software available online.


5. Hitting the refresh button makes your computer faster.

Most windows users have a habit of pressing  F5 key on the keyboard or right-click on the mouse to refresh their desktop. Refreshing the desktop is perhaps the biggest computer myth among Windows users. 9/10 users think that hitting the refresh button makes their computer fast. Sometimes, when you install a new software on your computer it does not appear on your desktop instantly, hitting refresh button comes handy during this time.


6. Drain battery to zero before recharging

People think that draining their battery completely before recharging will increase or maintain their battery life. While this was true for the Nickel-Cadmium batteries, it hardly matters in the case of Lithium-ion batteries. In fact, Li-ion batteries last longer if you keep their charge between 40-80%. Though you might have to drain it completely after a full charge once a blue moon to make sure that the battery meter remains calibrated.
