What is the Windows 10?

Windows 10 is an operating system from Microsoft Corporation for servers, desktop PCs, laptops, tablets, phones, and other connected devices (i.e. Internet of Things). The OS was formally announced on September 30, 2014, in San Francisco with Microsoft’s Joe Belfiore and Terry Myerson on stage. It was released worldwide on July 29, 2015.

Windows 10 for Phones was released as a Technical Preview on February 12, 2015 to various Lumia phones. The OS had the internal codename ‘Threshold’.

A Technical Preview for the OS was launched on October 1, 2014 by Microsoft for users to try an early version of Windows 10 for feedback. On January 21, 2015, Microsoft revealed the consumer side of Windows 10, including its plans for mobile and gaming. The final unveiling of Windows 10 took place during Microsoft’s Build 2015 conference.

Windows 10 ‘skips’ Windows 9 for its name for various reasons, including it being such a big update that it moves beyond just a single number upgrade.

Windows 10 gives users more choices between using the Start Screen (ideal for tablets and touch-screen devices) and the Start Menu (better suited for PCs and traditional laptops). A forthcoming feature called ‘Continuum’ lets the OS automatically switch between tablet and desktop mode depending on the presence (or absence) of a mouse and keyboard. Users can also override any settings, making the default Start Menu or Start Screen their choice.

Other features in Windows 10 include multiple desktop support, Modern apps are scalable on the desktop, new Start Menu (combo of traditional Start Menu plus room for Windows Apps), new task view button, new snapping options for apps, and improvements to file explorer for quickly finding files. These moves are largely considered to have been made by Microsoft to win over Windows 7 users who have not updated to Windows 8 due to unfamiliarity and a steeper learning curve.

For developers, there is application platform and one store for all the apps, which can run on all hardware, regardless of form-factor. These apps are called ‘universal apps’ because they can be run anywhere.

On March 30, 2016 during their annual Build conference, Microsoft announced a Windows 10 Anniversary Update that would come as a free upgrade to current users. The update includes new features thanks to feedback from Microsoft’s Windows Insider program.

Apple fell to the altar, the media summarized 10 major mistakes in 2018

In 2018, for Apple, it can be said to be “Heaven and Hell”. Apple’s market value once broke through 1 trillion US dollars and became the world’s largest enterprise. However, after the release of iPhone XS/XR, the stock price went down all the way, coupled with slow sales and production cuts. After the bad air attack, there has not been a rebound. The technology website iFuun reported that foreign media summarized Apple’s top ten mistakes in 2018, or poor product design or marketing decisions, which allowed Apple to “go down the altar.”

 

First: The iPhone XS series has changed too little. The design of the iPhone XS series is almost the same as that of the iPhone X. It is only a new golden style and a 6.5-inch Max. Although the 2018 is Apple’s “S” small upgrade year, it is a radical mobile phone for Chinese mobile phone manufacturers such as Huawei and OPPO. Under the design, Apple’s conservative nature is dwarfed, and ultimately, it also reflects sales.

 

Second: iPhone SE is discontinued. The iPhone SE discontinued by foreign media evaluation is one of Apple’s most wrong decisions this year, because it personally ended one of Apple’s most affordable iPhone. In addition, Apple’s move is undoubtedly giving up those who like small screen phones.

 

Third: iOS 12 upgrade is not big. In terms of software, iOS 12 has almost no change compared to iOS 11. Apple’s explanation is to increase stability, enhance the user experience, and add new features such as Siri shortcuts. However, these new features are not obvious and have not been achieved. effect.

 

Fourth: iPad Pro is still not a real computer. Unlike the iPhone, the iPad Pro has received major updates this year, canceling the Home button, adding a Face ID, and the full screen design looks beautiful. However, compared with its high price, the iPad Pro is still not a real computer, can not complete the heavy operation, and is less practical than the Surface Pro 6.

 

Fifth: The new MacBook Air design changes are too small. The MacBook Air was finally updated in 2018. The screen frame is narrower and the new processor is upgraded. However, the change is limited to this. People are actually looking forward to a brand new Air.

 

Sixth: HomePod lost to Amazon Echo. HomePod was released in February this year and is a brand new hardware category for Apple. However, compared to Amazon Echo, it is just a follower, although the sound quality is excellent, but wisdom as a smart speaker, and the high price is also prohibitive.

 

Seventh: Siri is still too stupid. In the era of Jobs, Siri debuted with the iPhone 4s and became the first AI voice assistant. However, after so many years, Siri is still a little poor, completely compared to Amazon Alexa, Google assistants and even Xiaomi Xiaoai students, is Apple’s most tasteless software service.

 

Eighth: Black Friday promotion is too small. The foreign media believes that in the case of Apple’s new product price increase in 2018, the “Black Five” discount activity is too stingy, and basically does not provide any meaningful discount. For example, the $50 discount is limited to the old iPhone 7/8 series, and the new machine cannot be used.

 

Ninth: No AirPods 2 and AirPower. AirPods is Apple’s most successful product launched in recent years, and its popularity is higher than that of the iPhone. However, in 2018, Apple did not publish AirPods 2 as expected, and its wireless charger AirPower continued to be difficult to produce, giving a very bad impression.

 

Tenth: The price of new products is too expensive. Finally, the 2018 new Apple new product has a drawback is too expensive. Whether it is iPhone XS, XR or iPad Pro, new Apple Watch and notebooks, the price increase is at least 20%. Although there are inflation and material labor costs, there is no technology manufacturer like Apple that keeps the old design and raises the price sharply, so it is not surprising that the sales volume has dropped.

When the mobile phone is charging while playing, does the power consumed come from the battery or the charger?

Let’s first take a look at the battery usage when charging. When the phone is charging, the current from the charger will be divided into two parts. Most of the battery will be supplied to help the battery to be stored. The other part will be supplied to the phone’s motherboard. Meet the needs of the phone to do other work. If it is used while charging, the current supplied to the main board of the mobile phone will increase, and accordingly, the current supplied to the battery will be reduced.

 

Since the battery can only be in the one-way working state, either charging or discharging, it is impossible to output power while inputting the power. At this time, it depends on the power of the charger.

If the power of the charger is very high, it can bring a huge current, so if the mobile phone is used while charging, the battery will always be stored, that is, the power is always increasing; but if the power of the charger is very low, or The quality of the data cable is not good, and the power consumption of the mobile phone is very large, so the power from the charger will be in short supply. How to do it? At this time, it is necessary to use the battery storage power.

 

Therefore, when the power of the charger is high enough, the mobile phone can still be charged when it is used, but the charging time will be longer; when the power of the charger is not high, the charger can not only charge the mobile phone but also need to be powered by the battery. The mobile phone will be charged less and less.

This latter situation is very common in the past, but with the popularity of fast charging, the power of the charger is very high, so the current mobile phone can basically meet the charging while using.

 

However, because the charger charges the battery, in the process of converting electrical energy into chemical energy storage, heat is generated due to loss; at the same time, the mobile phone generates heat when it is operated under high load, so the mobile phone will appear hot.

So the conclusion is that the phone is used while charging, and the power consumed comes from the charger. Unless your charger has low power or poor data quality, you will need the battery to supply power.

 

In addition, although the mobile phone can be fully charged while using it, the heat generated in this process will damage the battery and reduce the battery life; there are also uncertain risk factors such as an explosion.

Therefore, it is recommended that everyone use the mobile phone reasonably. Not only does the mobile phone need to replenish energy, but the person himself needs to rest. The mobile phone will also produce health problems such as cervical spondylosis and myopia.

Huawei plans to develop “super charger”

According to the foreign media “GSM Arena” report, Huawei, a Chinese smartphone manufacturer, plans to introduce a “supercharger” that can support the rapid charging of large-capacity batteries in the near future. According to official development documents, Huawei’s charger will provide 40W fast charge and can fully charge 4200 mAh battery in one hour.

Huawei’s new smartphone Mate 20 Pro released, its ultra-large capacity battery, it takes a while to fully charge through the included charger, which has disadvantages for users; the new 40W fast charge can make Mate 20 Pro users charge their batteries in a very short time.
However, according to the outflow data, this 40W supercharger currently only supports Huawei Mate 20 Pro, and other mobile phones can only provide standard QC 3.0 fast charge (the premise mobile phone needs support). Huawei expects to launch the charger in 2019. The foreign media also believes that this will coincide with the P30 Pro handset that Huawei plans to launch next year, while the lower-profile P30 may use a 20W fast charger.

What is the fast charge mode?

Mobile phone manufacturers are limited by the size of their mobile phones and their battery capacity is limited, so they began to turn their attention to fast charging. Fast charging is a technology that increases the charging power of mobile phones within a reasonable range and aims to quickly replenish most of the power for mobile phones. The charging power is equal to the current multiplied by the voltage. There are currently two solutions that can increase the charging power, high voltage, small current and low voltage and high current.

For example, the process of charging a mobile phone is like a process of dripping a mineral water bottle with a hole in the bottle. To speed up, first squeeze the water bottle to make the water flow faster, which is the high voltage and small current. The second is to tie another hole. At the same time, the water flow doubles. This is the low voltage and high current.

High voltage and small current

In 2013, Qualcomm introduced the Quick Charge 1.0 standard to increase the charging efficiency by increasing the input current, allowing the handset equipped with the Snapdragon 600 processor to support 5V/2A”/charging. However, due to the limitations of the micro USB interface, the input current should not be too large, so Quick Charge 2.0/3.0 can increase the power by increasing the supply voltage, which can achieve 9V/2A. In 2016, Qualcomm introduced the Quick Charge 4.0 standard, which is said to support the optimal voltage intelligent negotiation algorithm to provide the most suitable charging voltage for the battery. In addition to Qualcomm, MediaTek’s Pump Express Plus 1.0/2.0, Samsung’s Fast Charge, and Meizu’s charge 3.0 also use this high-voltage, low-current solution.

Low voltage and high current

Remember to charge for five minutes and talk for two hours? In 2014, OPPO introduced VOOC flash charging technology with a charging power of 22W. VOOC flash charging is a typical low-voltage and high-current solution, but as mentioned earlier, the micro USB interface will limit the current, so OPPO has customized the charger and charging cable, and even the internal circuit of the mobile phone has been modified to support 5V/4A. At present, OPPO’s dual-cell SuperVOOC super flash charging has a maximum charging power of nearly 50W and can charge 40% in 10 minutes. Also using this solution is Huawei SuperCharge Super Fast Charge, plus DASH Flash Charger.

Most Android phones that support fast charge will be equipped with a fast charge charger. There are exceptions, of course, so don’t ignore the accessories when buying the product. Be sure to look at the voltage and current requirements above.

High-voltage small current and low-voltage high-current are all in order to solve the charging problem, and there are differences due to different solutions to the micro USB problem. But now it is progressing, becoming smarter and safer, and micro USB is now undergoing changes, and mobile phone charging will become more and more perfect in the future. But now, you can turn on the “power saving mode” or choose the right fast charge charger to speed up.

Lift Camera

The reason why the lift camera appears is also a result of the full screen, looking for a “home” for the “nowhere to put” front camera.

It must be said that the design of the lift camera is sufficiently creative and practical, and it has achieved satisfactory results in terms of lifting speed, photographing and unlocking. The process is accompanied by sound effects and is very sci-fi.

Although there are many full-screen formats at present, I believe there will still be a mobile camera phone next year.
