10 mistakes when using a smartphone

Ten years ago, the telephone was a luxury, and it was treated with anxious and careful attitude. Now this is the most common thing, so many treat smartphones with disdain, making banal and sometimes dangerous operating errors.

Mistake # 1: neglecting the cover
A case is one of the most useful phone accessories that performs several important tasks at once. The first and foremost is the protection of the gadget. If the back cover and side panels are made of plastic, then with active use, after a couple of months, scuffs will begin to appear on the case.

These apps free up RAM so that the phone can subjectively run faster. Meanwhile, on Xiaomi smartphones, it is enough to press the function button (usually made in the form of a square) and click on the “cross” in the center. After that, open applications will be unloaded from RAM.


If you need to clear the cache, then use the standard tools. Let’s say in Xiaomi it’s the Security app where you can do a quick and complete cleaning. Standard tools work just as well as third-party applications, while downloaded programs usually only take up the smartphone’s memory. You can read more about cleaning memory here .


For the same reasons, you can choose not to install applications to save battery: all the necessary tools are usually available in a standard shell, including a battery saver mode.

It is recommended to install applications only from trusted sources, namely from Google Play. If you download software from third-party sites, there is a high chance of catching a virus.

Mistake # 7: unprofessional cleaning of your smartphone
In the course of even careful use, dirt, dust and small debris will accumulate in the connectors and speakers of the phone over time. This will affect the operation of the device. For example, if the speakers become clogged, the phone will play quieter. Dirt in the USB connector can cause the phone to stop charging.

Dirt can be removed from the connectors, but do so with extreme caution. Users use needles, toothpicks, paper clips and other improvised means. They can damage both the speaker and the USB connector, and in the worst case, also close the contacts of the microUSB or Type-C connector.

If you are going to clean your smartphone, use only a professional tool. The smartphone must be powered off. You can learn more about cleaning your phone and even the cover in this article .

Mistake # 8: neglecting updates
The iOS and Android operating systems receive various updates on a regular basis. They fix bugs, add new features and optimize smartphone performance. Even if you think your gadget is working correctly, there may be hidden vulnerabilities in the firmware that can be exploited by malware.

You can check for updates in the smartphone settings. Usually this subsection is called “System Updates”.

However, the latest firmware installed on an old smartphone can make things worse. The new version may take up more memory space and consume more RAM. Accordingly, when launching various applications, the phone will start to slow down due to lack of RAM. We recommend that you read the reviews of other users with a similar smartphone model before updating. Additionally, back up your data in case something goes wrong during the update.

Mistake # 9: using inappropriate storage devices
A standard charger is guaranteed not to harm your phone. However, they are often broken and lost, so you have to buy a replacement.

First, do not pursue cheapness, especially if the origin of the charger is not clear. These power supplies are unsafe and could cause a fire. Better not to save money and buy branded goods.

Secondly, select the same amperage and power as a standard power supply. It makes no sense to take models of lower power, since the gadget will take longer to charge. You can buy a more powerful power bank, but only if your phone supports it. The built-in power controller will automatically select the optimal profile and allowable voltage.

Mistake # 10: being afraid of the harmful effects of a smartphone on the body
Every smartphone generates electromagnetic radiation. SAR (Specific Absorption Rate) was introduced for mobile gadgets. This is the specific absorption coefficient, which shows how much energy of the electromagnetic field is absorbed by the human body per second.

There is still no consensus on which SAR is considered dangerous. Radiation less than 1.6 W / kg is considered guaranteed safe. Most modern smartphones meet this standard. However, there are nuances. So, in Europe, the acceptable value is 2 W / kg, but it is measured for 10 grams of body tissue, in the USA, 1.6 W / kg is acceptable, but for 1 gram of tissue. And in Russia it has its own way. Our radiated power is measured in W / cm 2 . For this reason, it is almost useless to compare SAR values ​​for smartphones from different manufacturers.

It is believed that exceeding the SAR can cause fever, dizziness and nausea in those who are sensitive to this type of radiation. However, all that is known for certain is that smartphones can interfere with medical equipment such as pacemakers. If you do not use medical devices, you should not be afraid of smartphones, unless you can move the smartphone away from you while you sleep. And it’s not about radiation.

Many people charge smartphones during sleep. Meanwhile, a device, especially when connected to a network, may catch fire or explode. If this happens, it is preferable to keep the smartphone as far away from you as possible.

Do not play mobile games and try to minimize talking on the phone when connected to a charger. This leads to overheating of the smartphone and, accordingly, increases the risk of fire or explosion.

Proper use of the smartphone will not only prolong its life, but also protect the owner. Be sure to install the latest updates from the developers, use cases and quality chargers. Then the smartphone will serve you flawlessly until the moment you decide to change it to a new one.

Moreover, scratches can appear even on metal panels, so covers are useful for such models as well. Maintaining a presentable appearance is especially important if you plan to sell your phone later.

The second task of the cover is ease of use. A metal or glass surface can be very slippery, making it difficult to hold the gadget in your hands. The solution to this problem will be a cover made of silicone or anti-slip soft-touch plastic. You can find out more about choosing a cover in this article .

Please make sure the case has holes for charging, earphones and speakers before purchasing. If you play a lot on your smartphone, be sure to do a stress test. The cover must not overheat the processor. If temperatures reach critical, then you should look for a “breathable” cover.

Mistake # 2: wearing a smartphone incorrectly
The most dangerous option is the back pocket of your jeans. First, it is not safe. Your phone can fall out of your pocket and you won’t even hear it if it falls on snow or grass. Secondly, the phone sticking out of the back pocket is extremely attractive to pickpockets.

Another common problem faced by those who carry a smartphone in their pocket is the deformation of the case. Even models with metal inserts are subject to it. At best, only the case will suffer, and at worst, the entire screen.

A way out of the situation may be to buy clothes with pockets, the depth of which corresponds to the size of your smartphone. Or, put your phone in a small bag. We do not recommend carrying your smartphone in your pocket with coins and keys. Monoblock gadgets will only get off with scratches, while foldable smartphones will suffer from expensive flexible screens or connecting mechanisms.

Mistake # 3: persistent wireless networking
With active use, the smartphone battery lasts for 24-36 hours. Wi-Fi, Bluetooth and mobile Internet consume the lion’s share of the charge. Try to disable these features when you are not using them. Considering that they are all located in the upper toolbar, this is a matter of a few seconds. This also includes GPS. The smartphone is actively spending energy on searching for satellites, receiving and transmitting a signal.

Mistake # 4: incorrect charging
Almost all modern smartphones use lithium polymer or lithium ion batteries. Unlike nickel-cadmium, they have no memory effect, so there is no need to fully discharge and charge up to 100%.6.4 “Samsung Galaxy M31 128GB Black Smartphone

In one study, scientists compared the number of charge-discharge cycles depending on the percentage of discharge:

As you can see, deep discharge significantly reduces the number of cycles and leads to accelerated battery degradation. Of course, putting the smartphone on charge as soon as the first 10-15% are gone is problematic, so experts advise keeping the battery charge in the range from 20% to 90%. You can find out the details in this article.

Mistake # 5: using your smartphone in a hostile environment
For most devices, the operating ambient temperatures are 0 … + 35 degrees Celsius. This applies to both Apple models and most Android smartphones.

It is possible to go beyond these limits, but it is highly discouraged. At subzero temperatures, the discharge rate increases, and with prolonged exposure to frost, the battery may lose its capacity. That is why the developers guarantee the safe and stable operation of the gadget only at positive temperatures. This applies to lithium-ion batteries. For lithium-polymer batteries, the lower limit is -20 degrees, so small frosts are not critical for such smartphones.

It is forbidden to charge the gadget in minus, so do not even try to connect the phone to the powerbank outside in cold weather. In the worst case, this can lead to critical degradation of the battery. Gadgets with metal and glass bodies are most susceptible to frost. Foldable smartphones are especially vulnerable to frost, the flexible screen can simply break if you try to open it outside. Plastic has a significantly lower thermal conductivity, so such smartphones can handle cold more easily.

High temperatures are equally dangerous. Extreme heat, a blanket thrown over the gadget, or direct sunlight affecting a smartphone with a lot of battery wear can cause the device to overheat. In the course of a chemical reaction, the electrolyte begins to actively heat up and release carbon dioxide, which heats up the battery even more. Eventually, the accumulated gas breaks through the envelope and an explosion occurs. These are quite rare cases, but they should not be ruled out, especially if it is +40 degrees Celsius or more outside.

Mistake # 6: Installing Useless Programs
There are dozens of apps online that promise to speed up your phone and increase productivity. Some of them really slightly improve performance, but in the Android OS you can do it yourself using standard functions.
