Ultimate Gaming Phone; OPPO K13 Turbo Pro. India's Only smartphone with a Cooling Fan.

OPPO K13 Turbo Pro 

Recently, OPPO released a gaming phone with a Cooling Fan. The fan is very powerful and cools your phone for the ultimate gaming experience. Let's check out it's specs.

Cooling 

Micro powerful fan system helps in the major cooling of the the phone. The fan blades are 0.1mm in size and has upto 18,000 rotations per minute (RPM) with a duct outside the phone it can release the heat from inside. It also has cooling fins just beside the fan which improves heat dispersal by 3 times. Other than the cooling fan it also has a cooling vapour chamber; 7000mm chamber at just 0.29 thin VC design with thermal conductivity graphite accompanied with thermal conductivity gel. There is also OPPO's cooling fan which we can buy and strap on the back for more cooling.

Gaming Performance and Processor

K13 Turbo Pro is powered by the ultimate lag killer; Snapdragon 8s Gen 4 with 4nm which is very small(the smaller the better) and a benchmark of 2,200,000 AnTuTu score. All of this cooling is effective in gameplay giving us 25℃ smooth gameplay for 3 hours continuously. With settings of 120fps we can play with no lag or frame drops. It is amazing it keeps the phone at just 25℃ even after playing for 3 hours straight and 120 frames! The CPU has 8 cores with clock speed 3.2GHz.

Battery 

It has a long lasting 7000mAh battery with 80 Watt fast charging. It is built to last with upto 5 year durability. It can charge from 0% to 100% in just 54 minutes! It has an intelligent charging system with features like: and 

 Battery Protection

This charges the battery to 80% for better battery health 

 Ultra Fast Charging

This gives efficient and super fast charging and adjusts temperature on how it is set.

Charging Declaration

This slows the charging when we are charging it during nights or when we are asleep. This will improve battery life and capacity.

Cold Mode

This preheats the battery when it's too cold which gives poor performance so the device heats itself to room temperature for better gaming performance.

Bypass Charging

When we charge our phones during gaming instead of directly supplying power to the battery it straight up powers the other components of the phone like the chip, display etc. This reduces temperature from 5-8℃ as heating when charging is because of charging and discharging, but the battery is not charging here.

Display

K13 Turbo has a display with 120Hz Refresh rate and 17.27cm or 6.8 inch screen size with 1600nits brightness with Blue Light Technology which is safe for our eyes even though we wouldn't stop gaming.

Google Veo 3; AI Video Generator. Too Good?

Google Veo 3

Google Veo 3 was launched in May 2025 at the Google's annual I/O developers conference. It was a simple text-to-video model, you can create realistic videos by giving prompts, but it's no just another awful video generator, where people have 6 hands! Google Veo 3 is incredibly powerful, creating ultra realistic, life-like scenes of our given prompt. It is quite hard to tell if it's real or not. AI is getting really scary! But let's see what it can do. 

Realism

Veo 3 can generate video's as 4k quality with sound effects, ambient noise and human dialogue with captions. With creativity in our hands we can generate videos with prompts that give output just the way you imagined. We can create hyper realistic cinematic scenes and dialogues which fit the character. It can generate scenes of humans with natural looking movements with there hands and follows all physical principles making videos unbelievably realistic.

Audio 

Veo 3 can create videos with sond effects just the way you want them to be, with backround music, where we can tell it what theme it should be; happy, sad, thrilling etc. In videos with human interactions it can create dialogues with the sound of the gender of the person, the way the person says it, how loud it should be etc. We all these features we can use our creativity to max.

Disadvantages 

What would happen if these powerful AI video generators got in the wrong hands? As these videos are getting too realistic scams, fraud and misinformation increase. At this point we can really tell if videos we watch are real or not. So we must be careful to not fall into scams. This also eliminates the meaning of videos of proof. In court a person can easily create a video of a innocent person doing a crime, in future even with AI decrypting we wouldn't be able to crack it. It will also be able to create fake videos of real people for blackmail or manipulation.Imagine five years from now! 

Here are some videos generated by Google Veo 3:

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.
