10 'standard' technologies are no longer accurate

Macs that are not infected with viruses, overnight charging quickly corrupt smartphones, the more "dots" the better the device is not true in today's technology age.

Mac computers are not infected with viruses

Mac OS X is rated for security and stability, but that doesn't mean it's immune to computer viruses. The first virus to attack Apple's platform was discovered in early 2006. In 2012, a trojan spread and affected thousands of Mac computers.

Incognito mode ensures privacy

Web browsers are often integrated with anonymous browsing mode, Google Chrome and Firefox called " incognito ", Safari calls with " private " name. This mode means that the browser will not save your history, bookmarks or login information. However, website managers and Internet service providers can fully grasp the information you have implemented, so be aware when accessing the web even with incognito mode.

Charge your phone overnight to make the battery go bad

Many people believe that fully charged phones that still plug in the charger will destroy the device while reducing device life. However, no research has proved this. Smartphones now mostly use lithium-ion batteries, it is smart enough to automatically disconnect the line when fully charged to protect the device.

Charge only when the device is nearly exhausted

Similar to the above statement, many people keep the habit of waiting for the device to run out of battery, and less than 20% to charge. This observation is no longer true in the smartphone era when most machines use lithium-ion batteries. Conversely, if the battery level is too low, it is harmful because some "cells" may lose their ability to charge. Li-ion battery life depends on the number of charging cycles, not the number of charging times.

The more cameras "dot" the better

Megapixel used to be the number used by manufacturers to advertise their devices. However, this parameter no longer determines the phone's image quality, when most devices have a resolution of over 8 "dots", enough for most needs.

A beautiful photo will need a phone with a large sensor, not a big "dot" number. The large sensor helps the recorder get more information, more light entering the image to make the image richer and brighter. Other factors that determine the quality of photos from smartphones are lenses, processing software .

The higher the screen resolution, the better

At a certain threshold, screen resolution is no longer an important factor for smartphones. Gizmodo quoted ophthalmologists as saying it was difficult to distinguish images above 300 ppi ( pixels per inch ). Some argue that high resolution will make the image smoother, but the difference is not big enough.

The smartphone market witnessed the race to increase screen resolution, from HD, Full-HD to Quad HD screen. Manufacturers like Samsung, LG, Oppo, and HTC all launched 2K screen smartphones, while Sony and Apple are still out of this game.

Charging iPhone with iPad charger breaks the device

The specs on the iPad adapter are twice as high as the iPhone, but Apple says the loader can be used normally to charge the iPhone. Studies show that the work does not affect the durability of the device, with the tablet's adapter, the iPhone also charges significantly faster than the charger with the phone.

Leaving the magnet close will cause the computer to lose data

This is only true if you are using a floppy disk, and the current hard drive requires a powerful magnet. According to PCMag, data on current computers is only lost if subjected to extremely large magnetic fields, with concentrated force. So magnets and common magnet objects around you cannot damage data.

Phone causes brain cancer

The phone emits radiation that the human body can absorb, but there is no convincing evidence that mobile phones are the direct cause of cancer, the BI report said. This is also the information given by the American Cancer: So far there is no evidence from studies on cells, animals or humans that radio frequency can cause cancer.

Wave number determines the network speed

Wave is information to let users know that their phone is connected to the network in good or bad condition. However, even if you are full of waves, you still have trouble calling if there are too many people, the network speed may still be slow.
