It would seem that we do not know about smartphones? Now they have almost everyone. But even the most popular device can be for people not very knowledgeable in the technologies subject to various myths and misconceptions. In the yard in 2017, and you're more religiously believe that a smartphone should be fully discharged before charging the battery first, and that the number of processor cores affects its performance. Then, this article will surely be useful to you. In it, I tried to collect the 9 most common myths about smartphones, in that it is high time to stop believing.
Myth 1. smartphones need to install antivirus
Not a week goes by like some company that specializes in computer security publishes the terrible statistics of malicious programs for Android. Naturally, this is done in order to allow users to buy their antivirus software, often with a lot of advertising. But let us look at this matter more deeply. As in Android-based know the Linux kernel, which is responsible for all processes. It is implemented on a "sandbox." Each application has its own user ID and memory directory, so that this application becomes protected from others. Therefore, even if the virus gets into your device, it will have access only to the memory card (such access have all applications). Therefore, in fact, do not exist on Android viruses in the conventional sense of the word, but there is malicious software that can access to your personal data. In this situation, the best solution is not to change the security settings that are configured by default, as well as to follow one simple rule - try not to install third-party applications from unknown sources. Statistics show that malware on Google Play virtually none.
With iOS system still easier. In all the years of existence of the operating system was only a couple of dozen cases, virus detection, and they were widely covered in the press. Primarily, this is due to Apple's tough policy with respect to the contents of the App Store, as well as high security systems. Also worth noting is that the usual antivirus software in the App Store, but there is a variety of browser security, storage, etc. Therefore, to completely reduce and before the minimum risk of the virus on iOS: always update the system without jailbreak and do not click on suspicious links clearly.
Myth 2. Close applications maximizes smartphone
Another popular misconception regarding charging your smartphone. For many years, there is a perception that if you close the application in Task Manager, your device will keep longer charge and increase system performance. Even sadder, when users of smartphones are set so-called «Tasks Killer» - utilities that automatically closes the application, and thus supposedly increases the uptime and performance of your device. In fact, these tools only consume more energy, and the closing of the automatic programs only slows down the process run them. In other words, the Android system running applications only look neglected. In fact, they remain in the phone's memory, so that next time they can be quickly opened, so they do not consume charge your smartphone. Moreover, the system automatically keeps track of applications that have not been included, and closes them to clean the memory. On iOS, everything happens in the same way. The system automatically closes the applications that have not been used, and the multitasking window - this is just the latest screenshots of running programs.
Myth 3. The need to fully discharge before the first phone charging
Strange, but many people still believe in the myth that was relevant because 10-15 years ago. Indeed, the earlier phone sets, iron-nickel and nickel-metal hydride batteries, which after the first purchase should have been fully discharged and then recharged. Otherwise, they place severe chemical changes which reduced their capacity in the future. For example, if the first time you put the telephone charge at 40% charge, then as he remembers total volume of 60%, and eventually reduce the total battery capacity. With the advent of lithium-ion batteries, everything changed. In today's batteries is not the so-called "memory effect", on the contrary manufacturers is not recommended to fully discharge the lithium-ion batteries. This is due to the fact that the life of such batteries is measured in the number of full discharge cycles. Therefore, charge your phone more often, do not bring the charge level to below 20%, and your battery will last you even longer.
Myth 4. The more processor cores, the more productive smartphone
A large number of cores, higher clock speed - all this of course attracts uninformed users, but in reality suspiciously high performance devices are often abstract. A striking example of this can serve as company MediaTek, which in 2015 year released 10-core processor Helio X-20, which used the principle of increasing frequency and three types of cores. In fact, users and experts did not see any substantial performance boost, so furor failed. Especially since today there are few applications and games that can be used in their work more than 8 cores. Another striking example is the Apple company. How not cool, but many tests have shown that 2-wire or 4-core processors apple company a significant performance 8-nuclear counterparts from other manufacturers.
Myth 5. Included Bluetooth consumes a lot of energy
Theoretically, any embedded communication module affects your smartphone energy consumption. Any background process consumes battery power, but in the case of Bluetooth, the consumption is so insignificant that it can not take into account. Moreover, the majority of modern smartphones using Bluetooth 4.0 standard and Low Energy protocol, which significantly reduce energy consumption. Therefore, if you want to keep the charge of your battery, it is best rarely use the mobile Internet, Wi-Fi - module or decrease the brightness of the display.
Myth 6. The higher the resolution, the better the display
Among the many users, there is another well-established delusion - the more pixels, the better the image on the smartphone display. In fact, the human eye can recognize a single pixel at a value not exceeding 300 ppi (pixel per inch). As for this value, there is some debate. It may depend on the size of the display of the distance to him or on the characteristics of human vision, but in any case this figure is close to this value. Further increasing the pixel does not improve the display quality, absolutely as causes no visual effect. Therefore, there is no sense in it, as if marketers do not want to sell another smartphone with 5-inch display with a resolution of 4K. But such a display will consume much more energy.
Myth 7. The number of signal bands affects communication quality
Once a foreign portal conducted a survey among the population concerning the cellular communications. As it turned out, more than 30% of respondents believed that the number of cellular strips directly affects its quality. In fact, there is no direct relationship here. The number of divisions indicates a power receiving a signal from the nearest base station. In a typical situation in the distribution of mobile signal is influenced by many factors. For example, the earth's surface in the line of sight antenna urban buildings, moving objects, the height of the receiver location (mobile phone), elevator shafts or wiring of sockets, adverse weather conditions or network congestion.
Myth 8. The more megapixels, the better the camera shoots
Times go by, and quality assessment of smartphone cameras are still considered megapixels. These stereotypes are imposed on us by manufacturers for many years. But in fact, the number of pixels affects only on the resolution of the image, that is, on its size. In reality, for the quality of the photos is responsible pixel size - the bigger it is, the better color reproduction and wide dynamic range of the frame. The pixel number depends on the size of the captured light to them and, accordingly, the amount of noise in the picture. However, this trend is gradually changing. Many companies began to focus on pixel size and aperture. That is why in many new models of smartphones resolution of the matrix is reduced, but the photos are better. Moreover, experience has shown that the quality of the photos is influenced not only hardware, but also software and processing algorithms that can improve the picture even when the camera is not very good.
Myth 9. The more RAM, the faster the system works
This is another popular myth that was imposed on us by marketers companies. People are trying to buy a smartphone, as much as possible with a large volume of the RAM, but often do not even think, why they need it. If the most recently 2-3 GB of RAM was the ceiling, now go device with 4 and even 6 GB. Therefore, before you choose a smartphone with a large amount of RAM, you should understand a few things. Firstly, often the performance of the device depends primarily on software optimization. Second, to solve everyday problems in your smartphone is enough to have a couple of gigabytes of RAM. Extra memory, you may need only if you are an avid gamer or you need to set demanding program, which will take up a lot of RAM.
