New Launch: Samsung Galaxy S25 Edge; Beyond Slim

The New S25 Edge 

Recently, on May 13 Samsung released the S25 Edge, said as the slimmest and lightweight Galaxy S model ever made. The last Edge model made by samsung was the Galaxy S7 Edge back in 2016, since then they stopped making Edge models and this was the next Edge model by Samsung. Here are the specifications of S25 Edge.

Dimensions 

The S25 Edge weighs about 163 g and has a thickness of just 5.8mm which is considered very slim or slimmest compared to other smartphone.The S25 Ultra weighs 218g and has a width of 8.2mm, The S24FE weighs 213g and has a width of 8.0mm, The S25+ weighs 190g and has a width of 7.3mm, The S25 weighs 162g, 1 gram lesser than S25 Edge! But sadly it has a width of 7.2mm.

 Performance

Even though the S25 Edge is very slim, it doesn't lack any performance issues, as it is powered by the Qualcomm Snapdragon 8 Elite processor for Galaxy with 12GB of RAM with storage options of between 256GB or 512GB. The chipset is the same one in the S25 Ultra. It has an Antutu score of 2,185,567, CPU-493,478, GPU-936,944.

Durability and Design

It comes with titanium frame which is very durable, and Corning Gorilla Glass Ceramic 2 protection offering the best type of protection, with curved edges unlike boxy edges from S24 Ultra, it also provides IP68 rating for both water and dust resistance.

AI features 

It has many AI features such as circle to search, Now brief, live translate calls, summarise webpages and many more. Here is a more clearer explanation:

The Galaxy AI allows us to Resize retouch images with Photo Assist. Which means we can change the size or retouch an object from an image.We can also take Stunning Low-Light Portraits with Galaxy's ProVisual Engine,which adds lighting to Portraits for a better look. AI also has a feature where we can imagine anything, Sketch it and AI will generate and add it to the image. With google AI we can use Circle to Search gesture which is very useful as we can search any image or text by just circling it.The Live Translate feature gives us real time voice translation while we are making a call with a person. It can translate any language to any other language by detecting it with AI,we also get interpreter for translation.

Camera

Unlike S25 Ultra with telephoto camera it only has a dual-camera setup featuring 200MP Wide camera and a 12MP Ultra Wide camera. But the Wide camera is 200MP, which is same as the one in S25 Ultra. It can take clear and excellent photos with it's 200MP lens. Also with Galaxy AI, it can enhance portraits and photos with it's ProVisual Engine.

Display

It has a bigger 6.7-inch AMOLED 2x display with QHD+ 1440 x 3120 resolution, and 2600 nits peak brightness better than the last model with 120Hz refresh rate for a smooth usage. But, sadly the S25 Edge does not have Anti-Reflective coating minimizing reflections, which is there in the S25 Ultra.

Battery

It has a 3900 mAh Li-Ion battery with usage time upto 25 hours on a normal scale usage. But on average you will get about 6-7 hours of use. It has a standby time upto 270 hours. Even though it is slim, it lasts throughout the day.

Software

One UI 7 

The S25 Edge supports One UI 7, or Android 15 which is the lastest software for Android devices. It is with the One UI 7 we get the Now Bar and new notification centre, and Now Brief and many more.

Colours 

S25 Edge comes in three colours; Titanium Icy Blue, Titanium Silver, and Titanium Jet Black.

How to Get a Better Battery Life on Smartphones? Tips and tricks

Increase Your Battery Life

Some smartphone users experience short battery life, some can't even get through the day after using for a short time. So, these are few tips and tricks you can use to increase your battery life.

Reducing Screen Brightness 

You may increase your screen brightness to the maximum, so your screen will look more brighter and better to watch movies etc. But increasing screen brightness to max can reduce battery life and is bad for our eyes. Increaase brightness can gives headaches and eyestrain.

Switch To Dark Mode

In our smartphones, it is set to light theme/mode by default. Switching your phones theme from dark mode to light theme can make a bigger impact on battery life, especially on phones with AMOLED display. You can easily do this by going to notification panel and there will be Dark mode or Dark theme options(varies in different devices)

Reducing Screen Timeout

In our phones settings, we can see display option click on it, then we will see 'Screen timeout' option. There, we can set the time our screen stays awake. If it is set at three minutes or more, then it can drain our battery fast as the display will be on if we don't switch it off. One minute timeout is considered healthy for better battery life. There is also 'Never' option in timeout which will never turn off the display, meaning it will be turned on till battery drains to 0% until we turn it off.

App Backround Activity 

Limiting background activity can give us much better battery life. Backround running apps such as Spotify, YT Music and many such run in the background even when we are not using them. These apps on run in backround when we play music then it runs even when screen is off. You can optimise your phone by using cleaner, stopping background usage by apps.

Power Saving Mode

In the quick notification centre we can turn on power saving mode giving us more battery, but less performance. Turning this mode on can reduce CPU usage by 70-80% reducing performance. This also reduces brightness by 10%(varies in different phones).

Battery Optimisation 

If none of these tricks work, try optimising your phones battery. Go to settings-Select battery option-Click optimise battery. After optimising it will say what are the problems with battery, background app usage, and battery capacity and more(varies in different phones)

India's Supersonic Dassault Rafale

Dassault Rafale 

 India is presently defending itself against     Pakistan by using French aircraft, The Rafale.   Following an agreement with French   company  Dassault Aviation, India now   possesses 36 fighter aircraft. The Rafale is   valued at about $7.6 billion, or ₹630 billion,   for  26 aircraft under the contract. With a   maximum speed of 1.8 Mach, agility, stealth,   and the ability to conduct intense combat   operations in a single mission, the Rafale is a 4.5-generation aircraft. Rafale is used by nations like France, India, Egypt, and Qatar because of its many capabilities. We will therefore talk about its defense capabilities and its function in safeguarding nations.

History of Rafale

Rafale Logo

In military parlance, the Dassault Rafale means "burst of fire" or "gust of wind" in French. The Rafale is a twin-engine, multirole supersonic fighter jet with a canard delta-style wing that was designed and constructed by Dassault Aviation, which was established in 1929 by Marcel Bloch. Since its introduction on May 18, 2001, it has produced 1,986 units and is currently in use.

Rafale World Wide

Dassault Aviation 

Since its introduction in 2001, Rafale has manufactured these assault aircraft for the French Air Force and the French Navy's carrier-based missions. The Egyptian Air Force, India Air Force, Qatar Air Force, Hellenic Air Force, Croatian Air Force, Indonesian Air Force, United Arab Emirates Air Force, and Serbian Air Force are among the nations that have purchased the Rafale for defense and other uses.

What Is Wireless Charging? How Does It Work? Explained

Inductive Charging

Inductive Charging, also known wireless charging was invented by Nikola Tesla later came to be used in smartphones, tablets, smartwatches around 2009. Nikola Tesla also showed how to light a bulb wirelessly. This technology helped us to change our way of charging in our devices. Simply, how this works is that you do not need to connect you phone or watch to charge, as it's name suggests it's wireless, there will be a magnet in the back of our phone and there will also be the same pattern of magnets on the charger, and we just put our device on top of it, then the device will charge with no connections. The first ever phone to support wireless charging was Nokia Lumia 920 launched in 2012. In some wireless chargers there won't be a visible magnet, instead it is inside it. But there is more sophisticated technology behind it, that is what I'm going to explain.

How this works

This process works by using Electromagnetic Induction. The charging base consists of a circle shaped coil which is powered by alternating current (AC) creating a magnetic feild which can be used for power transfer. When we place the device on the charging base, the magnetic feild leads to form current in the coil which is ready to get converted to direct current (DC), ready to charge the device's battery.

Disadvantages 

While you can charge your device easily without connecting, wireless chargers are often slow while charging and takes time. Most wireless chargers are either 15W or 20W which is considered very slow. Wireless chargers are also known for heating up during the charging process, and this is normal as electromagnetic induction process transfers energy it can quite heat up. Improper alignment can also cause these issues.

Advantages 

Belkin wireless charging powerbank

After introducing wireless charging smartphones there has been wireless charging powerbanks which have very slim versions. As these are slim we can easily stick it to the phone on the go. There also has been phone back cover with magnets same as the shape of the magnets inside them, giving us a stronger magnet so it wouldn't be loose and fall off.

Wonder

If you thought the battery used in wirelessly charging phones are different type battery, No, it is the same lithium-ion battery used in every other devices.

How Good Is An AMOLED display? How Does It Work? Explained

People have always wondered if AMOLED display is the best display technology that has been there since the early 21st century. 

AMOLED Display

The very first AMOLED
phone

AMOLED stands for Active Matrix Organic Light Emitting Diode. AMOLED technology had gained it's popularity in the years 2008-2009 in sales on smartphones, tablets, monitors etc. In the beginning AMOLED displays were invented in 2006 by Samsung SDI, although this technology was later then developed by other tech brands. The official founders of AMOLED technology are Ching Tang and Steven Van Slyke, and they both also introduced the very first OLED (Organic Light Emitting Diode) technology with Eastman Kodak company in 1987. The first ever phone to have an AMOLED display was the BenQ-Siemens S88, which was released in 2006, followed by iriver Clix 2 (2007), and the legendary Nokia N85 (2008).

How It Works

  AMOLEDs work

How this type of technology works is by using thin films of organic compounds which is carbon-based and is in the form of tiny molecules. The speciality of this material is that, it can glow when electrician is passed through it and this process is called electroluminescence, quite catchy! So, it is the role of these organic molecules to actually produce light in each and every pixel. These organic materials are chosen because, they are way more lighter than older LCD, LCD screens and are flexible. Because it won't break when we bend it, we were able to develop foldable smartphones like samsung Z Fold and Z Flip etc.

Advantages of AMOLEDs

Unlike other older LCD displays the AMOLED can light up each and every pixel independently when electric current is passed. So, the whole screen is not lit up like LCD and LEDs, giving us true blacks which is a completely turned of pixel. With this advantage we will get less eye strain as the full screen is not lit up and individual pixels can be turned off. Accompanied with true blacks we also get more vibrant, vivid, colour production compared to older LCD displays.

AMOLED display

We also get bigger battery life as AMOLED consumes less power, but this law applies only if you display darker content, as the black or dark spots need to be either turned off or can be adjusted with the brightness of pixels. So, using dark mode in phones can give us a huge leap in battery life. AMOLEDs also have faster refresh rates giving us from 60hz to about 144Hz.

Because of this, we get a smoother motion while playing games or when scrolling. SInce, AMOLED panels are flexible and are able to bend we were able to innovate foldable smartphones and 3D curved display smartphones.

What Is An LCD Display? How does it work? Explained

People have always wondered what difference there is between LCD and LED type displays, so today we are going to identify and discuss some of the key differences between them.

LCD Display

LCD stands for Liquid Crystal Displays, and was first invented in 1968 which made a whole new generation of displays from then. It was introduced by George H. Heilmeier at that time. LCDs are widely used in devices like TVs, smartphones, monitor's, computers etc.

LCDs work by using liquid crystals sandwitched between two transparent electrodes and polarizing filters. These crystals are not able to emit light on their own, instead the crystals twist and untwist thereby controlling the amount of light that should enter through them. When the crystals twist to one side the screen turns black, and when it turns to another side the screen turns white and bright. The liquid crystals are basically the heart of the display, controlling the light passage. Light source in this is the backlight which is often CCFL or LED, which shines through the crystals and the crystals change direction of light to form the image required. Every pixels that is there in the screen is divided into other three sub-pixels that is; red, green, and blue. These three colours are also called RGB. By adjusting the brightness of each pixel we can create any shade of a colour we want.

Microscopic image of LCD display 

The advantages of LCDs are that they are very thin and lightweight compared to other older displays, consumes less power compared to old CRT screens, provides sharp and vibrant colours and images, LCD TVs are often really cheap and inexpensive, and the other surprising feature that it does not emit light on themselves, and simply relies on the backlight.

Backlight of LCD display

There are also few disadvantages of LCDs. If you are watching something on an LCD monitor and you are looking at the screen in a low angle, you will see that the screen is darker, thus giving us limited viewing angles. The major disadvantage on LCDs are that they struggle to produce true black colours. On LCDs the black spot on the screen stays lit up, producing a dark blue colour on the area where it is supposed to be black. Prolonged exposure to LCDs may cause retinal photoreceptor cell damage, damaging our eyes which causes headaches, potential retinal damage and sleep disruption. So, it is best for us to take a break if you are infront of the screen for too long. However this problem can be solved by using blue light filters which reduces the amount of blue light entering our eyes.
