These legends smartphones hard to erase

Although we use them every day, our expensive smartphones technology have a sometimes dark operation, and some myths are difficult to make disappear.

Here is a small list that I see too often, so that you too can shine in society ;-)

Closing apps speeds up the smartphone: FALSE
Smartphone close applications

This error has logical bases, because sometimes we reason like on a computer where it is generally advised not to open 50 software at the same time so as not to suffer performance declines.

The temptation is great to also close applications on his favorite mobile device from the list of recent applications.

The difference is: these applications do not run in the background, and therefore do not consume resources. They are simply stored in the RAM to be able to return to it more quickly. But if the device needs more RAM, it releases applications that you have not used for a long time.

Yes, iOS as Android allows applications to perform actions in the background, but this has nothing to do with the list of recent applications.

No need to close these applications frantically, it's useless. Worse, no need to install a task killer on Android for this one function.

You have to empty the battery completely before recharging: FALSE

Here again, it is a myth based on the old technologies of memory batteries, which required to be fully discharged before being recharged, otherwise their ability to decrease more quickly.

We still see today some people hesitate to connect their device because it is already 80% loaded ...

And yet, the modern Lithium-ion batteries on our smartphones, tablets, and even laptops, have no need to be fully discharged before being recharged, so you can connect them whenever you want.

In the same way, it is not necessary to fully charge the battery before disconnecting the charger.

By the way, some tips to recharge your smartphone or tablet faster.

Do not leave your smartphone charging all night: FALSE, but ...

In reality on this point, there is truth and falsehood.

Legend has it that letting the battery charge for a long time while it is full could damage it, forcing the charge when it is no longer needed.

This is false because modern batteries can detect very well when they are fully charged, and therefore stop the charging process if necessary.

However, leaving a device permanently connected to the sector causes unnecessary heating and energy consumption ... to moderate therefore for ecological issues.

If you must do it, I advise you to turn off the device, and think about unplugging it when you wake up.

Only use the charger delivered with the phone: FALSE

<troll> This paragraph is obviously not intended for owners of iPhones who must change the charger almost every new version of their favorite device. </ Troll>

For all other devices connecting with a standard micro-USB cable, there is no problem to use another charger (it was a little trickier when switching from mini-USB to micro-USB because it was necessary find the right cable, but this problem does not arise today, except for the owners of antiquity).

If you use a larger intensity charger, your smartphone will use only the intensity it needs, it may even recharge a little faster than the conventional charger.

If, on the other hand, you use a charger of less intensity, it will recharge maybe less quickly, or not at all in the worst case.

Some additional info.

A protective screen film is essential: FALSE, but ...

With the development of screens equipped with Gorilla Glass, our mobile devices have become much more resistant to scratches and even falls.

Its specifications evolve even regularly, the third version released in early 2013 has increased its scratch resistance by 40%, and version 4 released in November 2014 indicates that glass can withstand 80% of falls to a height of one meter.

In other words: this type of screen will not be scratched by the keys in your pocket, or even if it is scuffed by a knife or cutter blade. The proof on video (sensitive souls abstain .. The guy is still able to break his screen, but I let you discover what he does to him for that.You can be sure that no screen protector would have changed anything).

The material used for the screen is simply stronger than all the metals used for these objects, so it is virtually safe. There is often more chance that these objects scratch the shell of your smartphone rather than its screen.

In fact, only a few very hard materials can damage a Gorilla Glass screen, such as diamond (I guess you do not trim every day in your pocket), or ... sand. So be careful if you spend a lot of your time at the beach.

Not to mention the special case of entry-level devices, or old enough, that would not be equipped with Gorilla Glass. It's up to you to check according to your device.

Apart from these particular cases, I think it is therefore not necessary to add a screen protector film, which in addition are generally quite cool to ask, and sometimes change the touch or even the responsiveness of the touch screen.

In the same spirit, I used to tend not to want to add unsightly shell to my smartphones, I changed my mind recently. For the record, it is by falling on the edge at the impact location that the screen exploded, it might not have happened with a Gorilla Glass 4. Everything has been in order since for cheap and a few hours of work ... but I added a shell since ;-)

More megapixels = better photo sensor: FALSE

In the same way that the amount of RAM or the size of the hard disk will not tell you if one computer is better than another, we must not rely solely on the criterion of the number of pixels to judge the quality of a computer. digital camera.

The legend is stubborn, it must be said that it is part of the annoying little manias of the manufacturers to sing the praises of their product on the basis of technical characteristics, which alone do not mean much.

For example, we often highlight the quality of the photo sensor iPhones, and even the iPhone 6 embarks a sensor of "only" 8Mpx when many competitors offer 16Mpx or 20Mpx or more.

From what I read the bidding of pixels to even have a perverse effect on the overall quality of the image (source in English)

There are many other criteria to take into account, such as the overall quality of the sensor, the embedded software ... which are much more difficult to measure. Probably the most effective way is to go for serious tests on the web, or even better to get your hands on the coveted device to make his own opinion.

We can easily catch viruses on Android: FALSE, but ...

Already, one should not speak of a "virus", but of malware, which in principle does not have the capacity to spread from device to device.

However, we are regularly told about "antivirus" for Android, I have already done the test of one of them (but I have not even written an article as the adventure has gone short ).

So yes, this type of applications exist, but apparently the number of devices involved and very low, and above all, this mainly concerns smartphone owners who install software that does not come from Google Play.

I imagine that these (of which I am a part) know perfectly well the risks incurred, and take the minimum precautions necessary to guard against them.
