Why smartphones get slow??!!

Dear Friends,
Slow Phones

Today, New Discuss topic "why mostly smartphones are get slow?"


Most of thing slow down as we age. We are similar to common machines, like old cars or hairdryers that run less efficiently as they get on in years.

But digital gadgets, like smartphones? We expect them to operate quickly. Forever!


 As you know in reality, smartphone performance eventually diminishes. Take my experience with each of the smartphones use over the past several years. Once each was more than a couple of months/years old, they showed the telltale signs of age, including frozen screens, apps that would load slowly or not at all, text messages that would not get delivered and unable to received phone calls .

There are several reasons smartphones get slow. According to Mike Gikas, who has covered and tested smartphones for more than a dozen years, “The main reason why phones slow down over time is that operating-system updates often leave older hardware behind. Companies also update apps to take advantage of faster processing speeds and more efficient architectures.”

1. Older phones have lots of apps, which slow performance
2. Too many apps are running in the background
3. Lack of storage space
4. Cellular network updates only benefit new phones

Smartphone experts point to an additional reason we think our old phones run slowly. Many suggest that consumers expectations of new, more powerful phones actually influence their perceptions of their existing phones. “It’s psychological,” says Gikas. “The newer phones are, indeed, faster, even though it’s only by fractions of a second. But that’s enough for some people to notice that the phone in their hand seems slower than their friend’s cool new phone.”

Wi-Fi Invented By Accidentally



A scientist from Australia, The name of scientist is Mr.John Sullivan was inspired by Stephen Hawkings theory of evaporating black holes and their subsequent radio waves, and set out to find them and prove the theory. Whilst doing so, he found that these weak signals were hard to distinguish from the louder background radio noise of the entire universe. Signals had traveled such vast distances and were so small and distorted by the gas and dust of space they had passed through. This meant their waveform had altered from a sharp and easily identifiable spike, to a flattened curve. It was because of this that O’Sullivan and his researches contemporaries got to work on creating a tool that could identify and filter specific radio waves. After lots of hard work, O’Sullivan and a colleague were able to create a tool based off a mathematical formula which would help them find these waves, blocking out the extraneous radio signals to identify the useful ones. However, they were unsuccessful in finding a black hole’s radio waves.

Fast forward to 1992,  Sullivan was working for the CSIRO and was tasked with finding a way for computers to communicate without wires – a wireless system of some type.

Remembering his previous research into black holes and the tools he is created to identify the black hole radio waves wireless,  Sullivan went back to the tool previously made. Using the mathematical formula of this device he was able to modify and tweak it, using this as a basis for Wi-Fi to search out weak and fuzzy radio signals in the noisiest of environments.

Battery Free Phone || Make Calls Without Ever Charging a Battery

What is the Battery Free Phone?

We present the first battery-free cellphone design that consumes only a few micro-watts of power. Our design can sense speech, actuate the earphones, and switch between uplink and downlink communications, all in real time. Our system optimizes transmission and reception of speech while simultaneously harvesting power which enables the battery-free cellphone to operate continuously. The battery-free device prototype is built using commercial-off-the-shelf components on a printed circuit board. It can operate on power that is harvested from RF signals transmitted by a basestation 31 feet (9.4 m) away. Further, using power harvested from ambient light with tiny photodiodes, we show that our device can communicate with a basestation that is 50 feet (15.2 m) away. Finally, we perform the first Skype call using a battery-free phone over a cellular network, via our custom bridged basestation. This we believe is a major leap in the capability of battery-free devices and a step towards a fully functional battery-free cellphone.

What is the God Particle || Higgs boson ??

What is the God Particle ||  Higgs boson



The "God particle" is the nickname of a subatomic particle called the Higgs boson. In layman’s terms, different subatomic particles are responsible for giving matter different properties. One of the most mysterious and important properties is mass. Some particles, like protons and neutrons, have mass. Others, like photons, do not. The Higgs boson, or “God particle,” is believed to be the particle which gives mass to matter. The “God particle” nickname grew out of the long, drawn-out struggles of physicists to find this elusive piece of the cosmic puzzle. What follows is a very brief, very simplified explanation of how the Higgs boson fits into modern physics, and how science is attempting to study it.

The “standard model” of particle physics is a system that attempts to describe the forces, components, and reactions of the basic particles that make up matter. It not only deals with atoms and their components, but the pieces that compose some subatomic particles. This model does have some major gaps, including gravity, and some experimental contradictions. The standard model is still a very good method of understanding particle physics, and it continues to improve. The model predicts that there are certain elementary particles even smaller than protons and neutrons. As of the date of this writing, the only particle predicted by the model which has not been experimentally verified is the “Higgs boson,” jokingly referred to as the “God particle.”

Each of the subatomic particles contributes to the forces that cause all matter interactions. One of the most important, but least understood, aspects of matter is mass. Science is not entirely sure why some particles seem mass-less, like photons, and others are “massive.” The standard model predicts that there is an elementary particle, the Higgs boson, which would produce the effect of mass. Confirmation of the Higgs boson would be a major milestone in our understanding of physics.

The “God particle” nickname actually arose when the book The God Particle: If the Universe Is the Answer, What Is the Question? by Leon Lederman was published. Since then, it’s taken on a life of its own, in part because of the monumental questions about matter that the God particle might be able to answer. The man who first proposed the Higgs boson’s existence, Peter Higgs, isn’t all that amused by the nickname “God particle,” as he’s an avowed atheist. All the same, there isn’t really any religious intention behind the nickname.
