Why Smartphones Heat?? Reasons Behind It

(1) Overload
Overloading is a big reason for the smartphone heating issue. If you are doing multiple tasks such as; playing a heavy online game with downloading a heavy file on background, then the processor of the smartphone can not handle it and the phone starts to heat. Also if you are downloading a lot of heavy files in a same time then also the smartphone starts to heat.

For more info go to

(2) Processor
It is the main part of the smartphone. All the functions of smartphone control by the processor. So generally this processors are made from semiconductors. And this semiconductors are consists of many electrons. When our phone starts to work then the electrons in the processor starts to move & when they interact with each other then heat generated. So then the heat starts to release from the phone & we feel this heat.

(3) Battery
It is also a main reason for the smartphone heating issue. Generally at the time of charging every phones starts to heat. But some smartphones temperature increases more during the charging. It only happens by the battery. Because now the smartphones battery is very slim & small. When the heat generate during the charging process, it starts to release from the battery but due to small size & slim there is a short place to release the heat. So that the temperature of the phone increases more.

(4) Room Temperature
It also affect the smartphones. Suppose in your location the temperature generally 35 degree to 40 degree. So it does not affect the smartphones. But if the temperature in your location reaches 45 degree to 50 degree & it continue then it affect your smartphones. So that the smartphones temperature increases.

(5) Poor Signal
This is the most important reason for the smartphones heating issue. Many times in our locations, the signal does not reach properly or some times for heavy traffic the network speed goes down. So that when we use our phones for net browsing, then its start to buffering & take a long time to show the result & automatically for this reason the smartphones starts to heat.

Many times the smartphones companies & manufacturers send the software updates regarding many types of heating issues. So that always check for those software updates and update your phone in the latest version to prevent this types of heating issues.

These viruses can transfer if you connect a CD, DVD, Pendrive to a corrupted system.

These are also a type of malware that enter into your system in different ways. When the Worms enters into the system they creates multiple copies of a same file or folder. So when they create multiple files in your system then your computer loses its space and will became slower.

It is a type of malware which enters into your system through different apps. When you download a free antivirus app or memory cleaner app then through this apps there is a chance of Trojan attack. Generally when it enters into a system, you can not feel its activities. Behind the scene it corrupts your whole system. But when you get inform about it, at that time it is too late. It already corrupt the whole software of the system.

How To Be Safe

5 Common Mistakes That You're Making With Your Smartphone!!!

(1) Overcharging & Low Charge
This is a very common mistake.Many smartphone users charge their devices before they sleep then pull the plug when they wake up many hours after. For this long time charging there could be pose a problem because Li-ion batteries usually reach 100 percent charge between two and three hours.The temperature rises when the battery is overcharged &, not only would this shorten the battery life due to stress, it may also threaten a user's safety, just like those batteries that quickly heat up and explode.

Many users spend a lot of time in the social media sites, watch movies for a long time but they forgot about their phones charge.When it hits 8 to 10 percent charge then they realize about that.
Li-ion batteries are designed to perform its best between 30 to 80 percent capacity so, once the battery hits lower than 30, feel free to charge your smartphone.Likewise, once the charge hits 80 percent, you really don't need to wait for your phone to reach 100 percent anymore.

(2) Tapping On Links
Smartphone users are more susceptible to phishing attacks than desktop users. They tend to be less vigilant about security. It is harder to spot a fake login page on a smartphone than on a computer. Further, shortened URLs make it harder to detect illegitimate addresses.The best defense is to avoid clicking on links sent via SMS or instant messaging apps. Also, always open email links using your computer.

(3) Joining Public Wi-Fi Networks
At many places like railway stations, airports there are the public Wi-Fi networks. It may be cheap but they are also a major security risk.Information sent over public Wi-Fi networks is visible to anyone on the network if they know how to view it.Hackers can easily steal your information & remotely access your device. If you must use a public Wi-Fi network, connect to the internet using a VPN (Virtual Private Network). It is a method to connect websites securely even on public networks. In other way, use your mobile data at that place.

(4) Forgetting To Install Updates

Time to time the Smartphone manufacturers & app developers issue software updates to improve the security patches & functionality of the smartphone. But many users avoid this, they use a old version for long time. But you should accept those updates to your phones operating system as soon as you are notified. The same goes with apps running on your phone. So regularly update the software running on your device give the phone a better performance.

(5) Forgetting To Log Out

If you are always logged into Amazon, Paypal & other sensitive sites where your finances are within easy reach, then you are doing a big mistake. Because on the shopping sites, recharge apps you also submit your credit cards, debit cards, bank details etc. It is very sensitive. So don't keep your phone permanently logged into such websites. Don't check the box in the app that asks to save your username & password. It is convenient not to have to log into the app every time but it exposes you to considerable financial risk. If your phone were to be stolen, a thief would have unrestricted access to your finances & you could end up with a massive bill for things you never bought.

How AC Works?? Types Of AC??

For more info

The Air Conditioners are use to cool your home by keeping a perfect temperature. But do you know how these air conditioners are work? And how it gives a cool temperature? So here you will know about the working process of air conditioners and also about the different types of air conditioners.

How AC Works??
Generally there are three main parts of AC by which it works. Those are (1) Compressor, (2) Condenser and (3) Evaporator. Except these there are also chemicals use in AC by which the hot gases inside the home transfer to outside the home. In AC, the compressor and the condenser are the external part where the evaporator is the internal part which located inside the home.

The chemicals use in AC convert the hot gases inside the home into liquid and then the fluid enters into the compressor with low pressure. But it exists the compressor with high pressure. Then when these fluid or gas enters into the condenser then there is a high pressure occurs but there are the fins present inside the air conditioner which release the hot gas more fast. So when the fluid leaves the condenser then it becomes more cooler and the high pressure converts the gas into liquid form. After leaving from condenser the fluid starts to enter into the evaporator through a small width hole and the pressure drops when the fluid reaches near to the evaporator. Then the fluid evaporate into gas. So after when the fluid leaves the evaporator then it becomes low pressure gas.

Then the fins inside the evaporator circulate these cool air across the evaporator and the AC sucks the air through a vent. And with the help of this air the gas becomes cool and the heat remove from the air. And this cycle continues from compressor to evaporator till the cool air comes. So in this way the room get a comfortable  temperature from the air conditioner.

Types Of AC
There are generally 4 types of air conditioners that people use mostly i.e;
(1) Inverter AC
(2) Non Inverter AC
(3) Window AC
(4) Split AC

* The compressor of inverter AC works in a variable speed. It maintains a constant temperature and the noise in this of AC is very low. There are also a low power consumption in case of the inverter AC. But the price of inverter AC is more than a non inverter AC.

* Then the non inverter AC consumes a high power as compared to the inverter AC. The noise of the non inverter AC is more than the inverter AC. And the price of non inverter AC is less than the inverter air conditioner. So an inverter AC is better than the Non inverter AC.

* Then come to the Window AC and Split AC. The Windows AC fits in a window and all the parts of the AC are together but in case of Split AC, there the compressor and the condenser are outside the home where the evaporator is inside the home. Windows AC have more noise than the Split AC and the air circulation in the Split AC is more than the Windows AC. But the price of Windows AC is less than the Split AC. So here the Split AC is better than the Windows AC.

This computer is totally depend on the electricity. If you switch on then it will work and if you switch off then it will stop working. Generally, the computer understands two numbers which is zero and one. All the information and data store in a computer are in the electrical form. They are flow in the circuits and wires in the form of electricity. And in this electricity form the information are in zero and one format. These zeroes and ones are called as Binary Numbers. So when this information are come to the output then it convert into the pixels or waves. Actually this happen because when the electricity flows in a circuit or wire of a computer then it is 1 and if there is no electricity flows then it is zero. So all the information in a computer are in binary numbers form.

But the output appears in the screen by going through many paths. For example, Suppose in a computer you click the mouse in a particular file. Then the input command goes to the motherboard and in motherboard it will be verify and then store in the memory. After that, from the memory the input data goes to the CPU and then the processing takes place. During the processing, CPU modify the input data and collect the related output. These outputs are in binary numbers but when it come to the screen then it convert into a readable or audible or video format.

For this fastest response between the input and output there are many components responsible like the Computer processor, CPU, GPU, RAM, Clock Speed etc. When the CPU receives and collects data's then these components have a great role. Without these components the input and output process will not be possible. During the data managing by CPU, processor is need to process the data where the RAM and the Clock speed make the data transfer more fast. And the GPU (graphics processing unit) manage the graphics to display in the screen. So, if the components are good then the CPU will work better and you will get a better experience in the computer. But, if the components are slow means low RAM, low processor, low GPU or slow clock speed then obviously the computer will not perform well and you will not get a better experience.

What Is The Clock Speed Of A Device?? Explained In Details

For more info

As you know the smartphones and computers have the CPU, GPU, RAM and Processor. There are also a clock speed that indicates how much the processor is fast. So Clock speed of a device is a very essential feature for its performances. You all heard about the GHz or MHz which are the unit of the clock speed. So lets know more about the clock speed.

You know that the CPU and GPU are work for the data manage and graphics. But if you consider about the integrated circuit then they are work in a particular sequence. And there are a clock present which on or off the circuits in a particular speed. These circuits will perform well if the clock will on or off more times means if the clock will on or off more times in a second then the complete circuit will work properly. Here the performance of the circuit help the transfer speed of the data. The data transfer speed increases and the processing of data will be very fast.

If you consider about the smartphones then there are different clock speeds are available. In a normal phone and a flagship phone there are different clock speeds are available. For example,if a phone having low RAM, low processor and less internal storage then the phone need a low range clock speed. Because in a low range clock speed that phone can perform well. But if there is a flagship phone having more RAM, high processor and more internal storage then the phone obviously need a better clock speed.

Then if you consider about the computers then here you do multiple task in multiple tabs. So as compared to smartphone here the clock speed is more.

But the processor also affect the clock speed. Suppose consider two phones having same specifications but one is new and another is old. Then if the design of the processor is different then the clock speed will definitely differs. So at last lets know about the GHz and MHz.
"GHz" is known as Gigahertz which means the clock switching 1 billion times in a second and "MHz" is known as Megahertz which means the clock switching 1 million times in a second. So according to the processor and work speed the clock switch more times.

What Is GPU?? Graphics Processing Unit In Details

For more info

The GPU is generally known as graphics processing unit. In simple we can say it is a graphics processor. In smartphones and computers the GPU have a great role. Gaming, video playing all are possible for this graphics processing unit.

The smartphones and computers having millions of pixels in their display. Now-a-days the 720p screen contains 1 million of pixels where as the 4K screen contains 8 million of pixels. These pixels are work by the control of GPU. When you play a video or start a game in your smartphones or computers then it start to play with the help of graphics processing unit. The GPU sends the command to the screen to play the video or to start the game.

Before the GPU placed inside the mother board. But now a time the GPU is placing in a different place. Then come to the integrated GPU which is a part of the processor which monitors & process the graphics and send commands to the screen, to give an output. This process continues and happens 60 times in a second.

The GPU specifications are very similar to the specifications of a computer or smartphone. The smartphones and the computers having the RAM, processor, mother board like that the GPU also having RAM, processor and mother board. Its performance is totally depend on its RAM and processor. If the RAM and processor of a GPU is more then the performance of the GPU is also excellent. So it works by its capacity.

To give the output in the monitor there is digital to analog converter inside the RAM. So when the graphics processing unit sends the command to show in the screen then first it goes through the converter and then the output show in the screen.

The GPU was first develop by the NVIDIA in 1999 and this company developed the world's first GPU called as GeForce 256 which has over 22 million transistors. As compared to CPU, the working principle of GPU is totally different. CPU controls the whole system where as the GPU only controls the graphics part. But in some GPU the transistors are more so that some time it works more than the CPU. If the GPU of a device is not good then its graphics are not work properly. Suppose a system has a low quality GPU and you're playing a heavy game, then the graphics performance will not excellent. There are some other stuff's will be appear. So a good visual needs a good graphics and it will be possible by a good GPU.
