Ah, the world of tech myths! Despite countless efforts to kill them, a host of myths continue to persist. While many of them are result of plain ignorance, a few have genuine lineage. 

However, as the technology moves forward most do not hold true anymore.

Here's debunking 9 of such fallacies.

This, too, is a popular myth about lithium-ion batteries. It's not harmful to plug your phone in before the battery is drained — in fact, it may be better for your battery. 

Batteries have a limited number of charge cycles before they lose their ability to hold a charge.

Yes, they can. Malware such as trojan horses could affect Mac OS X operating systems in the same way as Windows. However, although Macs are not immune to viruses, attacks are rare. 

This is because the virus has to be specifically designed for a Mac and most are targeted at businesses who tend to use Windows.

Despite being one of the most-commonly held beliefs about digital photography, a photo's quality is determined by many more factors than megapixels. 

A camera's lens, circuitry and sensor -— not to mention your mastery of lighting, composition and the camera's controls -— are far more important factors.

Various studies have attempted to link laptops, mobile phones and Wi-Fi with male infertility. However, basic science tells you that the laptop itself is not the problem, but the heat it generates. 

The testes are stored in the scrotum, outside of the body, to stay cool. Therefore, sitting with anything hot on your lap for a prolonged period of time is best avoided.

It isn't, but nor was it designed to slow people down, which is another myth. The Qwerty keyboard is one of the finest examples of how the best technology doesn't often win. The Qwerty design was intended to avoiding internal jams on the machine. 

By the time a more efficient keyboard was invented -- the DVORAK, which has vowels and frequently-used consonants in the middle -- Qwerty had become well entrenched.

LCD and LED do not even refer to the same part of a television. LCD refers to the technology in the TV screen and includes plasma and OLED, an up-and-coming technology. 

LED means light emitting diode and is effectively the backlight which lights up the image. Every modern television, including LCD ones, now uses LED.

All smartphone operating systems aren't created equal, making this myth tough to break down. Windows Phone 8 background apps operate in much the same frozen fashion as iOS — but there are exceptions.

The rise of MP3 players and the iPod made music more accessible to people arround the world, but at a cost. The sound produced by MP3 players was of a lower quality than that produced by CDs.
