Vivo Xplay5 fashion show

Cold wave sweeping across half of China some time ago, my Socialist successor was frozen when silly bi ~, it is estimated that many mobile phone users are ignorant force. If your friend has suddenly lost, don't worry, they are just awe-inspiring to measure what is called "cold shut" ... ...

That day, human finally back reminds had once was power insufficient by dominated of terrorist and phone didn't electric of that copies humiliation: see with also has 20% power, wild drag racing on left last a bent, to girlfriend of apologized micro-letter on poor a Word, Conan on poor a sentence words on can put killer pointed out that to, Taobao chop hand party on almost about paid, phone he Meow of actually shut machine has!!! (╯‵□′)╯ ┴─┴

Even the bottom of Maslow's theory of "power" they cannot guarantee that, also talk about from the Gallery! Even the battery indicator is our existence is: there's no more insecure? Embrace battery indicator the pit of endless grief, we decided to study important life topics: battery indicator on the phone really accurate?

Temperature test

Our prices in accordance with the selected 5 machines for testing, including the 5000-level iPhone 6s (Yes, it's "cold shut" case protagonist), the 2000 class Meizu MX5 and OPPO R7s, thousand-Yuan G7 level red rice Note3 and Huawei.

Introducing our call tool Fast and Battery discharge Monitor Widget, which can screen, Flash always and CPU frequency operation handset with fixed load discharge, while the latter is what most professional information tools, no one. Since no two iPhone software, so the use of slow motion and Flash a constant output.

In this fixed under load, the phone will power off at a linear rate, if the power curve is not linear, that obviously is the power statistics are not allowed.

At room temperature, 2000 Yuan and Qian Yuan level of several handsets are not chains, Huawei Technologies, in addition to the low end of the G7 have a certain degree of power hoax, but almost always coincides with the ideal power curve.

Low-temperature discharge test

Baby cold, baby, don't tell

Chemistry teacher told us that low temperature affects the speed and efficiency of battery chemistry, but power counting should not appear erratic or die suddenly. IPhone what what happened at low temperatures? Other phones will have an accident? We still speak with experimental data.

The test method and object is the same as above, but the test environment to 0 degree thermostat:

At low temperatures, iPhone 6s first just power off faster than usual, and curve drift often played, went to the second half with 1% stick to a half of an hour. But because the iPhone testing machine is new, and there were no frozen shut. Netizens are frozen shut because cell phone use after a period of time, power due to statistical errors.

2000-level machines, OPPO R7s power to a "step by step", but performed much better than several other machines, power degree under the influence of temperature is very light. The MX5, he was not very optimistic about next, whole machine power reports last 15% about power directly on the frozen shut.

Thousand units, red rice Note3 apart from fast early with a minor power, and the rest are best of 5 machines. But it's exaggerated power G7 next degree deviation from 25% capacity has died suddenly after ... ...

Why Mobile show different?

Apple says iPhone is actually a sudden shutdown on battery low temperature protection, but passionate power curve that floated face swollen by Apple.

Of course, as knowledge, culture, and the pursuit of four youth, there is Google, these guys are more interested in reasons for different mobile phone power counting accuracy differences, xiaobian shame shame to check the information ... ...

Full story from that humble fuel gauge on a mobile phone chip to start, members may have the impression, when Nokia brick when God, the so-called energy statistics are just a few of 3~5 lattice (pictured above). Although accuracy is very low, but a week filling device does not need much attention power. Later accompanied by really intelligent machine spread collapse of mobile phone battery, fuel gauge IC in technology upgrades, we are also a percentage battery indicator of better times.

From the former 3~5 to 100 today, accuracy has climbed more than 20 times, which the hero behind the scenes is the fuel gauge IC, but at different temperatures, different ages, different discharging current (power consumption of different tasks such as playing games, watching movies) they have available capacity fluctuations. Battery indicator accuracy is closely related to the fuel gauge, fuel gauge, however this effect of "security" component has been forgotten by everyone, information on the results of mobile phone manufacturers have no standard gauge but, we had to remove.

Teardown analysis

IPhone 6s fuel gauge hand of chips from Texas instruments, are placed in the package on the circuit board and batteries.

Specific models are special, is the Texas instruments tailored for Apple's SN27546. Marcelo Burlon iPhone Case

OPPO R7s excerpt from circuit board, using Texas Instruments ' power meter, chip placed on the independent circuit and directly connected to the battery plates, was surrounded by a bunch of sticky plastic insulation.

Specific models for the Texas Instruments BQ27541.

Meizu MX5 excerpt from circuit boards, the machine does not pick up stand-alone fuel gauge IC.

Huawei G7 excerpt from circuit boards, also did not carry stand-alone fuel gauge IC.

Fuel gauge model statistics Marcelo Burlon iPhone 5 Case

Teardown see marking on the chip and found that only 3 of the 5 phones phones using a stand-alone fuel gauge. Apple iPhone 6s, red rice Note 3, OPPO R7s used stand-alone fuel gauge, but Meizu MX5, Huawei G7 are not stand-alone fuel gauge IC, reported by the mobile phone power on CPU own estimates, low battery indicator accuracy, low temperatures there is sky in error, or even cold shutdown problems are inevitable.

MX5 battery discharge curve of the before and after comparison chart

In addition, do not use the stand-alone fuel gauge has offset problems of aging. In other words, in the course of normal use, as the battery ages, battery indicator error will continue to increase. To that end, we've included comparison of brand new and used MX5 in six months. Even at room temperature, use some time MX5, the discharge curves are something very touching off, is very routine use.

In actual use, if the phone with long battery indicator and no, that is likely to be a machine without a separate voltmeter to blame, these machines are very exaggerated power display errors may occur (MX5 don't look around, talking to you). Even more tragic is, battery the greater error, but this is exactly what we charge the most sensitive area ... ...

However, it is also a stand-alone fuel gauge, performance is also different. Red rice game micro-fuel gauge for use on Note 3, did unexpectedly well, iPhone 6s and OPPO R7s TI the fuel gauge, are markedly different performance at low temperatures. Cold shutdown event for so many years in the past, Apple's still not optimized for low temperature characteristics of fuel gauge, which is not very authentic.

The last nagging

Although user awareness is not high, but fuel gauge accuracy will directly affect our psychological forecasts of a cell phone battery life. Accurate battery indicator allows us to dare at the power of 5% playing an important phone call. If the battery indicator is inaccurate, even display 50% we will have to worry about the battery off the chains, this is related to a sense of important propositions.

But it is regrettable that, if not extreme weather, many using non-independent gauge of the phone there is no way to provide accurate battery gauge. In addition, if power calculated 10% of error, then the battery has a capacity of 10% never be able to use mobile phones battery life is reduced by 10%, the Diabetes Insipidus of battery life are not tossing.

In our talk about charging a five-minute phone call two hours before, Type c, graphite black technology, all vendor master, dare to optimize your battery indicator accuracy?

If you want to hide their identity others you don t agree

The journey has a, Silver King has a bottle, he called you out, if you promise you'll be Aquarius collection in. Pity is, bottles only names, you get a false names it does not know who it is. If it has introduced new road in the Scriptures as early as broken.

Blair Armstrong and his team just by letting people read out some very common words, such as FBI or DVD, or what, can with 94% accuracy, identify volunteer status. In other words, as long as you speak, Aquarius can take you. disney iPad cases

How is this a principle?

Because different words mean different things to different people-and thus cause a difference of brain waves may potentially provide a way for others to identify you. Researchers recorded the 45 volunteers in reading 75 when the list consists of the initials of the words brain signals, and then used a computer program to find differences between individuals.

Results show that brain waves can also be a security system validation to verify the identity of individuals. In this experiment 94% the accuracy of the provided insufficient security precautions, but this is a good place to start. It would appear that the Silver King to use this technology, also obtained from the magic spell on Monkey's brain waves.

In fact, based on electrical signals in the human brain to identify before the technology has been developed, significant advantages of this technology is that it can continue to be used to verify a person's identity and password or fingerprint provided one-time when you simply need to verify identification. Through the face or ear recognition, as well as by monitoring brain activity, such as authentication, in theory, allow someone to interact with many computer systems at the same time, even with all kinds of smart objects, without having to repeatedly enter passwords for each device.

But so far, all the noise associated with brain signals measured data is difficult to analyze. Blair Armstrong's approach is by focusing on one area of brain waves, and reading and identifying the word task to solve the problem. This produces clearer signals in the brain, and can be measured more quickly.

The brain is divided into episodic memory (episodic memories) and semantic memory (semantic memories), these brain signals are generated by semantic memory, records our experience episodic memory and semantic memory only records the specific meaning of the word. And different from episodic memory, semantic memory, the passage of time does not change too much.

Blair Armstrong believes that this technology could be developed based on semantic memory becomes a more personalized, more difficult to crack biometric method, an alternative to fingerprints or an iris scan. And fingerprints will suffer wear and even finger, and as long as you live there will not be the brain signals were cut off.

At this stage, Armstrong's accuracy than fingerprint or Iris, and because you want to place the three electrodes placed on the scalp, and also slightly inconvenience in use. We don't have to worry about saying that words can be identified and, of course, to prevent someone put something on your head.

ESA releases 3D video take you to understand Mars surface

　　Other than NASA, the European Space Agency ESA is also one of the largest collection of NASA Mars information. Recently, NASA released a series of Pluto, Mars, moon, space exploration archive Rob stole. Perhaps heart is unwilling, to compete. ESA uses information available in their hands and made a video of the 3D effect, to space exploration like friends all-round showing off some of the surface of Mars.

　　This video is not directly by the ESA Rover record, but ESA available around 7300 photos of Mars, through the 3D digital processing technology, spent 5 months time finished. Through video, we can clearly see the surface of Mars.

　　ESA has made this video, looks like a helicopter aerial photography of the Earth, however the difference is that--this is on Mars. The video, or use the ESA's first Mars probe "Mars Express" in more than 10 years ago, "early" photographs of Mars are brought together ESA for more than 10 years to build. Through video, we can see some on the ESA Mars terrain, such as mountains, craters name and so on.

　　Have to admit is that ESA is indeed not in the overall strength of NASA, but the effect in this video teaser, it seems to be. Paul Frank iPhone plus case Paul Frank iPhone plus case

Internet invasion of conventional car by car UI compete for the core is artificial

TV, PC, mobile, Tablet, consumer electronics market every screen has created a huge market. Power of the screen itself is not so great, of course, be content, based on the content in the same ecological system stability, adhere to the majority of users. Has long been "ignored" the car that control screens, whether as the Internet Interactive terminal, and future O2O one portal, is highlighting its importance.

Current car since the car is still in the "feature phones" stage, the nosy Internet giants are aware that this is another great opportunity. Apple Carplay, Google's Android Auto, Baidu to launch Carlife and music publishing LeUI Auto, first to enter the Internet firm has no precedent to follow, how to unify this screen with huge potential, and transform its original content?

Machine UI is what the hell

Car didn't start there. Car is not entertainment, and later radio, it added a radio on in the car, radio evolves into a cassette, cassette, CD, MP3, MP4 with multimedia functions, GPS now add 360 degree imaging, thermal imaging, and other functions.

Machine functions can be divided into two categories, one is related to the car itself, such as cameras, sensors, car air conditioning and so on. This category features third party difficult to make, require manufacturers to custom-installed and debugging.

There is a class of functions are additional features, such as radio, music player, video playback, map navigation, and now the Internet companies like O2O, strictly speaking, these functions are not on the car, tie plate with his mobile phone in the car as well. This is a third party can do, get most of the Internet companies do now staring at is this one.

Two development direction

Third party UI in two directions, one is talking with manufacturers, had its own UI pre-installed in cars.

LeUI Auto ready to go this way. Must be first installed into their car (although no one character of the car, just bought a United States electric car design company, baic's cooperation is possible).

Machine UI pre-installed the difficulty lies in the popularity of cars, automobile manufacturers used hardware varies, the operating system is also no uniform, to develop a suitable for all automotive applications is highly unlikely, and persuade auto manufacturers to use your machine hardware selected for Arabian nights. Google has tried to form a coalition but without success, walk this way can only say that it's not ready, or just do it yourself.

Apple Carplay, Google's Android Auto, Baidu Carlife is another way--"plus".

Simply one or more suitable for vehicles with integrated functions of APP, running on a Smartphone or Tablet (out with a mobile phone), the manufacturer retained an interface's car. Once connected, mobile phone onto the machine, using screens, audio, touch screen, CPU, memory, Flash, using smart phones networks. In this way since the car better entertainment and O2O experience. This has nothing to do with the car since the car most of the hardware and software, auto makers just specialize in one entry, easy to coordinate.

From the current situation, many businesses on the new model and Android support Carplay Auto.

UI core experience

Mobile UI compared to automotive UI, Tablet UI has some particularities. Because cars need to concentrate, UI operation is simple and convenient as possible, button needs to be large enough, level too many menus, press close to the driver, easy operation is necessary.

In addition, car UI similar to mobile tablet UI, were all beautiful, quick, animated transitions, and other basic things. Tesla's UI to be materialized before the Apple icon, button made light and shadow, 3D. Overall color coordination, consistent design style emphasizes, similar to the basic UI is the same. Need to be aware of is that UI is not a user interface would be finished, but all of the APP application to take into account the characteristics of the vehicle. Maps, music, applications, navigation application for each interface, each level of menu, take into account the driver easy, easy to touch the issue.

Letv did very badly in this regard. While Apple and Google, Baidu has noticed this.

UI also has a very important function of voice recognition and identification operations after judgment. Drive hands free little eyes stared at the pavement, precise voice command completion operations, experience better than any other gorgeous UI interface. In other words, natural language recognition, that is accumulated in the field of artificial intelligence, is the core competitiveness of future competition car. CarPlay currently even if Apple does not works. In addition, from functionality, things like music, entertainment, leading manufacturers are not doing too badly. On the experience gap O2O, Baidu combining map Carlife if popularized, will have an advantage over competitors. If the combination of payment more convenient.

Excellent machine UI is the

Current applications, good UI should have the following characteristics:

(A) additional machine mode, or is an independent free hardware, or through the interface provided by the OEM (Carplay or Android Auto), manufacturers may consider giving flat mode, only through a car stereo audio connection.

(B) the graphical UI should fully take into account each and every APP, every interface operation, press the size, location, level menu settings to facilitate the driving position accurate touch. Basic UI itself is solid, buttons, menus, color schemes, design of coordination. Animated transitions, smooth feel.

(C) the recognition of natural language to be exact, in particular noise reduction ability, at high speed and noise in the accurate identification of human voice. Speech recognition, semantic judgement, perform an action, is the core competitiveness of machine UI user experience. Givenchy iPhone case

(D) the O2O's most practical, current machines provide most of the UI features cars the machines can achieve, just difference of experience, O2O is bringing their own machines to accomplish, this is the Internet firm's strengths. O2O did well, determines the user there is no need to use the machines you UI.

UI can satisfy the above four conditions will have a future.

Almost perfect B W third generation Zeppelin speaker evaluation

　　Bluetooth speaker to say, Bowers and Wilkins "Zeppelin" that's a must. It combines beautiful design and excellent sound quality, is the pursuit of life quality of choice for fashionistas. Nowadays, the B&W releases new, third-generation Zeppelin Wireless.

　　Zeppelin Wireless comes with "the legend returns" describing too much. At the base of the iPhone generally very cheap, can lower your phone fashionable values directly, "Zeppelin" design and uncompromising quality of high face value for all stunning. Today's lost Zeppelin Wireless audio base, became a pure stereo, it can also do so full of charm? We are evaluating have a look at: Paul Frank iPad Mini Case

　　Design

　　Zeppelin Wireless consistent basic designs before and two senior, olive-shaped appearance is derived from the history of the famous Zeppelin airships, simple, beautiful, no place to accuse. Biggest difference is clear, did not base its whole shape becomes more simple.

　　Zeppelin Wireless profile is not just to look good, more acoustic considerations. Housing with a 90mm left and right sides of their respective intermediate frequency unit and a 25mm high-frequency unit, very symmetrical. Olive-shaped design allows covered four units left vacant on either side, try not to let anything affect the sound of the unit.

　　New speakers look old is basically the same, but inside there is no small difference. Zeppelin Wireless 50% thicker than the first-generation product, which is said to be due to the B&W think the first generation of bass is too strong, and want to improve the acoustic design to make the sound more balanced.

　　Musical performance

　　New design means that Zeppelin Wireless bass is bad? This is not so.

　　Zeppelin Wireless bass is vigorous, but not as early as some of the bloated feeling, but is even more clear, control and stronger.

　　Valuable is, strong bass without impact to the Zeppelin Wireless frequency, which sounds are very transparent. Vocals are clear, but not to the point of piercing. Speaker high resolution, you can hear the player's finger sliding on the guitar string sound.

　　Although Zeppelin Wireless figure is very small, but the sound is not small. Of course, as a single speaker, you can't expect it to sound layering and how high standards on the stereo.

　　Other technologies

　　Zeppelin Wireless uses interpolation technology, built-in decoders to allow those relatively low sampling rate audio, such as Internet streaming media, get to be better than the original. People who can afford such products are unlikely to compromise on sound quality so much, but a practical new technology is good.

　　Indeed, we see that B&W is through Zeppelin to broaden consumer Wireless Group, it is no longer limited to Apple's AirPlay, also carries Bluetooth AptX audio compression techniques, even traditional output interface to satisfy the traditionalists.

　　It is worth mentioning that, Zeppelin Wireless equipped with a brand-new DSP digital signal processor, making it in different volumes can be good musical performance. In addition, dynamic equalizer technology to intelligent monitoring audio signal and maintaining control over the sound.

　　General comments

　　New Zeppelin Wireless contracted but not simple, seemingly has been designed actually changes a lot. On the sound quality, if it is filled with details, bass-heavy and no swelling generally impeccable. If you want an uncompromising in every aspect of Bluetooth speaker, Zeppelin Wireless may be the best choice.

　　Of course, Zeppelin Wireless is not for everyone, its price of $ 699 for those who do not ask for too much sound, and who don't intend to a speaker for your home decoration, it is too expensive.

Picnic artifact came out lost to go

Swimming is not only a fitness, or is it a sports competition. We all know that, we can see the swimming pool there is a section of the lane. These lanes are designed not only to increase the utilization of the pool, more to athletes in training or competition do not interfere with each other. So, for those who swim in the open water athlete or amateur, in the vast lake, or swimming in the sea, any Lane, what should they do?

It is understood that many in open water swimmers will face a dilemma: it is hard to keep straight. Even if there is a buoy as a reminder, most people still have off-track problems, this loss not only physical strength, can also affect results. Many athletes say any lane as a reference, feel anxious while swimming. To do this, from the United States a team specifically for triathlon athletes and people like swimming in the open water navigation goggles designed, to provide users with a virtual channel to help users straight forward.

This is a smart called OnCourse Goggles goggles, using soft silicone gasket as frame, comfortable, even for long distance swimming, users will not have a burden. Also uses polarized lenses, anti-fog coating, and comfortable goggle, well visible, UV protection. Look, OnCourse is like regular goggles not too different, simple and elegant. Just Cavalli iPhone 6 Case

Configure OnCourse's primary design is its inherent, built-in high-precision electronic compass, tilt compensation Accelerator and the microprocessor of electronic circuit boards, lithium batteries, as well as professional and special software. Therefore, OnCourse goggles to help users accurately in a straight line, save energy, get better results.

Workflow

Operation is very simple, the user simply facing the destination direction, press the switch next to the goggles, OnCourse will automatically store the way forward. On the left and right frames of a LED lamp, as real-time feedback in a different color to remind the user to adjust routes, make sure that straight forward. When swimming in the water when you move in the right direction, the two LED lights are green. If you veer to the left, left on glasses of LED lights will turn yellow, if the user does not adjust, but move on, LED light will turn red. Similarly, if a deviation to the right, LED lights will change color to alert users to the right. Only when the swimmer back to correctly route, LED lights will become green again.

To a buoy and how to adjust a route? To compete in open waters, there will be many buoys as a guide. If the user completes the first buoy barrier, and how should I adjust it? At this point, the user does not need to operate any APP (under water), towards the next target, press a button, you can begin a new journey and move on. It is reported that the team now is working on a new feature, perhaps users through head movements can be set after the next direction.

In addition, OnCourse also has a waterproof USB interface, use the accessory USB connection, users can plug it in the computer, car or a iPhone plug to recharge. Officials say its built-in lithium-ion battery charging time is approximately 45 minutes, has yet to report life time.

OnCourse goggles currently on Kickstarter to raise activities, sells for $ 250. Current official issued a Mid-Orbit and Inner-Orbit versions, if raised to succeed, the team plans a third version, and add more colors available.

For more cool intelligent hardware information, please pay attention to odd public number (woaiqiku), in odd public key, you can buy, and I'm not gonna tell you, register as a member of Lei feng still get super discount.
