Gone are the days of the peculiar dance of the ports thanks to reversible connectors. We’re talking about the USB-C standard and the Lightning connector from Apple. Both are amazing and helpful for consumers, but the two are quite different. And no, it’s not a matter of Android versus iPhone.

What is USB-C?

USB-C, technically known as USB Type-C, is the latest and most versatile USB connector to date. If you happen to have a premium phone, you already have a USB-C port for charging and wired connectivity. If you have the latest MacBook or MacBook Pro, it’s the sole type of port on your laptop for wired video and data output, as well as charging. You will find USB-C on most mobile devices nowadays, even laptops, because it’s a standard that anyone can use. But not all USB-C ports and connectors are created equal.

A technical explanation as to why they’re not all equal is that USB-C is actually just the style of connector and port; the real power comes from the USB 3.1 technology it uses, which can deliver 100 watts of power and is capable of a 10Gbps data transfer rate. It also supports Thunderbolt 3 technology for an even faster 40Gbps transfer. But not all USB-C types have USB 3.1 or Thunderbolt 3 speeds, especially for mobile phones.

While the older USB we’re familiar with are mainly used for storing and transferring files, the new USB-C standard is not limited to that. It can relay images for displays with support for full DisplayPort A/V performance up to an 8K resolution. It’s also backward-compatible with VGA, DVI, and the trusty HDMI as long as you have the right adapters.

Since all USB-C ports and connectors look alike, it’s now harder to distinguish what the port or cable is for. Could it be a power source or for charging? Maybe for high-resolution video? Or high-speed data transfer? You’ll have to know the specifications to be sure.

What is Lightning?

Apple already had their proprietary connector with the early iPhones, but it was only since the introduction of the Lightning connector along with the iPhone 5 in 2012 that made their own design popular.

From a cumbersome 30-pin dock connector, Apple had a smaller and reversible one which was ahead of its time. Even the common micro-USB port can’t compete with the convenience of the Lightning connector. Since it’s proprietary, only Apple can use it and third-party accessory manufacturers have to pay a licensing fee to apply it to their products.

The technical specification of Lightning is pretty limited, but when it first came out, tests showed that its speeds were up to 480Mbps — the same with the old USB 2.0 standards. In 2015, the iPad Pro showed a faster speed of 5Gbps, but that’s still only half of USB 3.1 speeds.

What are the significant differences between the two?

It’s easy to differentiate the two based on their appearances. If you’ve ever used or seen an iPhone, you’re already familiar with how the Lightning connector looks with its pins exposed. USB-C looks cleaner and simpler with its symmetrical connector.

Again, USB-C refers to the style of the port and connector rather than the technology it has. It is convenient because it’s reversible and universal. The whole point was to have a single style of connector and port that could run pretty much everything.

The Lightning connector is solely used to connect Apple mobile devices like iPhones, iPads, and iPods to host computers, external monitors, cameras, battery chargers, and other peripherals. You won’t find it on any other device, even MacBooks.

Why is Apple not using the Lightning connector on MacBooks and will USB-C replace Lightning on iPhones?

Will we ever see a Lightning connector on a MacBook? Highly unlikely. But there’s a possibility that Apple will use USB-C soon on iPhones. Last year’s rumors pointed to the iPhone X having USB-C, but it didn’t.

With the new MacBooks relying purely on USB-C, an iPhone with USB-C is not far from reality. That’s unless Apple wants to keep the revenue from Lightning connector licensing.

Which is better?

When paired with USB 3.1 or Thunderbolt 3 technology, USB-C is faster, more powerful, and provides greater versatility than Lightning. It’s also now widely adopted for consumer technologies may it be on phones, laptops, or other mobile gadgets.

USB-C is the future. Apple already accepted it on their premium notebooks which kind of triggered professionals who are using MacBooks, but that’s the future we’re heading towards. It will come to a point where we’ll just plug in a cable and it’ll simply work. For now, we still need to understand the differences and live with dongles.

Here’s how India is trying to be China in the smartphone game

The world’s second-largest smartphone market has more to offer

Published

on

China is practically the world’s production powerhouse. And India wants to follow the same path. India’s Central government has approved three schemes to enable large scale electronics manufacturing and attract fresh investments worth almost INR 50,000 crore (US$ 6.3 billion) in the sector.

The government aims to provide companies a production-linked incentive of 4 percent to 6 percent on incremental sales for locally made goods over a period of five years. This not only includes mobile phone manufacturing but also assembly, testing, marking and packaging.

The other policy offers a 25 percent financial incentive for capital expenditure that goes towards “the manufacturing of goods that constitute the supply chain of an electronic product”. With these incentives, the government is optimistic that companies will come to India, contribute to progressing infrastructure, and make export-quality goods.

Inauguration of Samsung’s Noida Factory in India

According to their estimates, domestic value addition for mobile phones is expected to witness 35 to 40 percent jump by 2025, from the current 20-25 percent.

So far, companies have focused on assembling equipment like smartphones in India. A huge chunk of the components are still imported. These policy changes could act as a stimulant to locally source electrical components, semiconductors, as well as develop production clusters.

Bangalore and Hyderabad are infamous for their IT Tech Parks that house thousands of employees from IT service firms like TCS, Infosys, Accenture, and many more. Similarly, the government wants to create production clusters that can develop an eco-system of their own. These clusters can create a seamless supply chain when paired with proper land, air, and shipment infrastructure.

The timing of the announcement is what matters the most. China is embroiled in a trade war with the US for quite some time and we’ve seen how a giant like Huawei got caught in the cross-fire. Companies are skeptical about depending too much on China for production and sourcing. Hence, countries like Vietnam have witnessed a huge inflow of foreign investment from the likes of Nintendo, Foxconn, and even Samsung.

India is very much like Vietnam. A developing economy that’s on the look-out for foreign investment and enhances local production capabilities. This not only helps the government increase its tax revenue via taxation, but also provides employment. Considering the current Coronavirus crisis, it’s obvious that these plans may not materialize soon. But, as soon as the storm is gone, companies would want to find an alternative to China.

Prime Minister, Narendra Modi with Apple CEO, Time Cook

It’s reported that the alleged low-cost iPhone from Apple has been delayed due to the pandemic. Irrespective of the current health crisis, Apple has been trying to ramp up its local production in India and has done so, cautiously. India is the world’s second-largest smartphone market and every brand wants a piece of the cake. Realme and Xiaomi have been intensely fighting for supremacy, Samsung continues to lead via the offline market, and OPPO and Vivo have flooded all commercial banners with their products.

Xiaomi currently has seven plants in India, major ones being at Sri City and Sriperumbedur. It also makes its televisions in Tirupathi. Manu Kumar Jain, Vice President, Xiaomi, and Managing Director, Xiaomi India said that 95 percent of Xiaomi’s phones are made in India with 65 percent of a phone’s value being sourced locally. The government has been successful in compelling companies to make in India because it consistently kept on raising import duty on smartphones.

Samsung already has the world’s largest mobile phone factory in India that assembles top-tier variants, ready for export. We don’t know the volume it churns out right now, but their long-term investment is a precedent for other brands to take the market seriously. OnePlus has a research facility in Hyderabad where it makes software products intended for the Indian market.

Samsung’s factory in Noida, India

According to industry ICEA, the NOIDA region (a part of Delhi NCR) has close to 80 mobile manufacturing factories that provide employment to approximately 50,000 people. It’s normal today to see companies release press notes announcing new facilities across the country that’ll employ thousands of people.

Prime Minister Narendra Modi kickstarted the “Make in India” campaign five years ago to encourage foreign companies to invest and build in India. While its effects are debatable in a few industries, there’s no doubt that the mobile industry has picked up exponentially. State governments of Karnataka, Andhra Pradesh, Telangana, Uttar Pradesh, and Tamil Nadu have played a major role in establishing these clusters that symbolize progress.

Engineers are widely available in India, the country has developed multiple ports under the private-public model, and numerous airports are under construction. India is already the world’s second-largest smartphone maker, but the gap is huge. It’s about briding this. Obviously, the scale at which China produces is unmatchable. But that cannot undermine India’s efforts to be more relevant on the global stage. From a purely consumption-based economy, it’s slowly trying to turning into a production backed state.

Explaining smartphone display refresh rates

Are they really any different from PC displays?

Published

on

Smartphones, little by little, are turning into mini-PCs with the features that come with it. From browsing on social media to playing video games, technology is slowly adopting a more “on-the-go” lifestyle. Recently, smartphones have acquired another feature that your own desktop or laptop already has.

Some of the recently released premium and gaming smartphones now come with displays having their own dedicated refresh rate. Refresh rates aren’t new, but to see it on a compact device has a lot of people wondering. How different or similar is it to a PC’s refresh rate? And is it actually something good to have?

A crash course on refresh rates

A display’s refresh rate, basically is the number of times your display updates every second. Your screen usually takes a few seconds to just a second to load new images, depending on that rate. For example, a 60Hz refresh rate means that in one second, any image on your display is refreshed 60 times. Your eyes wouldn’t catch it fast enough, but that’s how your display works.

For most PC displays, the default is at 60Hz with companies releasing displays that range up to 240Hz. You mostly see this in displays fit for gaming purposes, since gamers prefer the higher refresh rate for improved performance. If you’re someone who mostly likes to watch movies, it really doesn’t matter how high the refresh rate is.

Note that this is entirely different from frame rates, in that these show how many images are produced within a second. Although, having a high refresh rate allows you to perform a lot better because it is optimized for higher frame rates. That’s why you see some gamers complain about playing on a 60Hz display.

Transitioning to a smartphone near you

Eventually, the concept of amping up a refresh rate will reach the world of smartphones. In fact, the OnePlus 7 Pro was actually the first mainstream smartphone to have a display with a 90Hz refresh rate. Most smartphones, even budget ones, have displays built with a 60Hz refresh rate. Something about it just makes you scroll through your phone without feeling too dizzy, unless you scroll too fast.

Premium smartphones mostly incorporate either a 90Hz or 120Hz refresh rate for a smoother UI experience. With higher refresh rates, scrolling through your phone feels a lot smoother without risking an eye sore. Of course, these smartphones do cost significantly more than your average, everyday smartphone.

Apart from premium smartphones, gaming smartphones have also incorporated higher than 60Hz refresh rates. Phones like the Razer Phone 2 and the ASUS ROG Phone 2 both come with a 120Hz refresh rate to suit mobile gamers, especially FPS (first-person shooter) gamers. With these higher refresh rates, mobile gamers see clearer images with less motion blur involved.

Do you really need all the hertz?

That begs the question: what do you need a high refresh rate screen for? When you use a PC, 60Hz is already good for most tasks and games. Trying to go for higher refresh rates usually means that you’re doing a lot more than the ordinary. Tasks such as heavy-duty data analytics or hardcore gaming are optimal for higher refresh rates.

The same logic works for smartphone displays, except on a smaller screen size. A lot of what you can do, you’re able to do so on 60Hz displays. If you’re just using your phone to browse social media, watch Netflix on the daily, and play games casually, you don’t need anything higher. Although, it is a premium to have if you want buttery smooth software.

If you play games competitively, you would prefer higher refresh rates just like in gaming monitors. Higher refresh rates allow you to perform at an optimal level when going for higher frame rates. We’re talking close to no image tearing or motion blur when you play PUBG Mobile or Call of Duty. While you can perform well at the default 60Hz, going for a 90Hz or 120Hz ideally makes the experience better.

Some final thoughts

Smartphone display refresh rates have always been a part of the technology. These displays were built in a way that everyone can benefit from them. It’s only fairly recently that smartphone companies came up with a way to make the experience a lot smoother. Hence, smartphones started incorporating higher refresh rates.

It almost feels like having that high refresh rate is a premium, given only select smartphones have it. But it’s a premium that you don’t really need unless you have a good reason to. Apart from the cost of experiencing it, it really depends on what you plan to do with your smartphone.

At the end of the day, it’s better to ask yourself if it’s a feature worth getting. If it’s something you feel you can’t live without, by all means, right?

Stranger Things 3: What exactly is an ignition cable?

Possessed Billy knew what he was doing

Published

on

By now, you’ve probably seen the third and newest season of Stranger Things on Netflix. If you still haven’t, it goes without saying that there are spoilers ahead and you should stay away from this article.

Seeing a pop culture reference such as Stranger Things together with the seemingly unrelated world of automotive in one writeup such as this could be strange (pun intended) for some. We really don’t mind and thought it would be a fun and unique way to talk about the show and learn a few things from it, as well.

So we ask the question: What exactly is an ignition cable?

The ignition cable is part of a vehicle’s ignition system. In simplest terms, it’s a mechanism that starts the engine. By generating a high voltage from the car’s battery to the spark plugs in its engine, it causes them to ignite the engine’s combustion chambers and get it up and running.

And in order to transfer that voltage from the source to the engine, you’ll need an ignition cable as it’s like a subway system that acts as pathways for the voltage to pass through. So if the ignition cable is not present, there’s no way to start the car.

Back to Stranger Things, Billy (although already possessed by the Mind Flayer) obviously still had his knowledge on cars so he took away the ignition cable trapping our favorite gang at Starcourt Mall’s parking lot.

Just to further stress the importance of an ignition cable and the whole ignition system for that matter, we’d like to visit other possibilities and ask, “What if Billy didn’t take it away?”

Well, the plan was for Eleven and her group to go to Bauman’s secret place and stay safe while Joyce, Hopper, and the rest try to close the portal and render the Mind Flayer powerless. If their ignition cable was intact, they’d be a lot safer away from the Mind Flayer although we wouldn’t be able to see that amazing fireworks scene inside the mall.

Through this, we see the importance of that one small part under the hood of the car. In real life, it really pays to make sure that everything is in good working condition and that one faulty cable could mean trouble for you if remained unaddressed — unless there’s a car on display inside a mall somewhere that you can take spare parts from!
