介绍:
To mark the iPhone&`&s 10th anniversary, Apple revealed its most expensive smartphone ever, iPhone X.
On Tuesday, the world&`&s most valuable company announced updates to its Apple Watch and Apple TV. But after unveiling a new line of smartphones, the iPhone 8, Apple CEO Tim Cook added "one more thing" to close the event at the Steve Jobs Theater in Cupertino, California.
Starting at $999, the iPhone X (yes, the company skipped the iPhone 9) has some of the most significant updates to the gadget since 2014.
With its edge-to-edge display and buttonless face, the new iPhone looks remarkably different from past iPhones. At 5.8 inches diagonally, its screen is taller and larger than the 4.7-inch iPhone, but smaller than the larger 5.5-inch iPhone Plus. The Galaxy S8–esque screen has a hardly noticeable border around it, making all kinds of content — video, articles, apps — appear full-screen.
The display’s immersiveness is largely due to the fact that instead of a home button, there’s just more screen.
It’s an update that’s likely to be just as controversial as the removal of the headphone jack last year, and the change from the 30-pin to Lightning connector in 2012.
No home button means that the way you interact with the phone will be different. Instead of tapping the button to see your homescreen, you’ll flick up from the bottom of the screen. To force-restart the phone, you’ll now long-press the power and volume-up buttons, and to invoke Siri, you’ll double-click the power button.
The biggest and most obvious trend in smartphones right now is the effort to eliminate the bezel, or frame, that surrounds a phone’s display. The goal is to create a feeling that you’re only holding a screen in your hand, and there’s nothing else to distract you from what’s being displayed on that screen. Established players (Samsung and LG) and newcomers alike are all trying to reach that goal.
the real change is the screen.
The iPhone X has an OLED screen, versus the LCD (liquid crystal display) in older models, which Apple is calling the “Super Retina Display” (that’s 458 pixel/s per inch, for you nerds). It also supports HDR, including Dolby Vision and HDR10 standards.
OLED screens display darker blacks, brighter whites, and more vibrant colors, and Apple is including a number of new wallpapers to show off the display. These screens are also more power-efficient and thinner than LCD screens, because they don’t require an always-on backlight layer. Both Samsung and LG have implemented OLEDs in various devices. In fact, the new iPhone’s display is reportedly made by Samsung.
True Tone, a feature that makes the screen easier on the eyes and was originally announced for the iPad, will also be available on the iPhone X. It can detect the color temperature of the room. So, for example, if the room has warm, yellow lighting, the phone’s display will look warm too (the same way a piece of white paper reflects the light around it).
The display has rounded screen corners (older iPhones have square corners) and completely covers the front of the device, except for a thin notch at the top. Because of this notch, the time has been moved to the top left, while the wireless icons are on the top right. This notch houses the earpiece (for calls) plus a new array of cameras and sensors designed to detect your face. Your FACE. Which brings us to...
xiaomi mix series
Xiaomi is also playing this game and it actually had a head start over much of the industry when it launched the Mi Mix last year. The Mi Mix was one of the first phones to come out with nary a bezel at all. Its enormous 6.44-inch screen was pushed to the very corners of the phone’s frame, and the entire design of the device was driven by this goal to eliminate the border entirely.
That drive forced Xiaomi to make some interesting design decisions, such as forgoing a standard earpiece for a fancy piezoelectric version and moving the front camera down to the lower right of the phone’s frame. Not all of these changes were good: the earpiece was far inferior to a standard speaker and despite the efforts to shrink the phone’s frame down, the Mi Mix’s enormous screen meant it was still a giant device. Xiaomi was likely aware of these issues when it labeled the phone as a “concept” device, even though it was available for purchase in the company’s home market of China.
Now Xiaomi has announced the Mi Mix 2, which rectifies some of the issues of the original and drops the concept tag. This new model is smaller and more approachable than the first Mix, and it will eventually be available everywhere Xiaomi sells phones.
The iPhone X has an OLED screen — here&`&s what OLED is and how it&`&s different from past iPhones
Apple announced a slew of new products last Tuesday, including three new iPhones: the iPhone 8, iPhone 8 Plus, and iPhone X.
There are several major differences among the three phones, but one of the biggest changes is the screen - the iPhone X is the first iPhone to feature an OLED screen, while the iPhone 8 and 8 Plus have an LCD screen like Apple&`&s previous phones.
The OLED technology is new for Apple, but anyone who uses Samsung phones (or the Google Pixel, or the new Essential Phone) is already familiar with OLED. In fact, Samsung has been using OLED screens since its first Galaxy phone came out seven years ago.
what is OLED?
OLED, short for organic light-emitting diode, is a type of display technology. It differs from the more widely used LCD (liquid crystal display) tech by creating light within every pixel that makes up its picture, instead of requiring a separate backlighting system.
This means it can produce perfectly dark blacks. Rather than trying to cover up a backlight behind the scenes and inevitably letting some light through, it shuts off the appropriate pixels. The result is an infinite contrast ratio - i.e., the difference between a display&`&s darkest blacks and brightest whites.
And that, in turn, means an OLED panel can produce a more vivid, realistic picture. If you&`&ve ever put a Galaxy S8 and an iPhone 7 side by side, you&`&ve seen the difference: Apple&`&s LCD display is excellent, but Samsung&`&s OLED display just pops more. It&`&s more engrossing. It&`&s thinner, too.
I&`&m simplifying - improved backlighting tech, wider color gamuts, and HDR have helped the best LCD displays catch up a bit. But stuff like that isn&`&t exclusive to LCD. Judged straight up, the contrast difference is enough to make OLED superior.
The drawbacks
OLED isn&`&t perfect. The displays are more prone to color shifting and are very vulnerable to burn-in, meaning that if you leave an image on the screen for too long, you run the risk of it being retained on - or burned into - the screen over time.
This isn&`&t a problem unique to OLED - LCD screens are also susceptible to burn-in. But the vulnerability is greater with OLEDs and could shorten the life span of your phone (though according to some reports, there are clues in the iOS code that Apple has taken special steps to mitigate the burn-in effect on the iPhone X).
Changes ahead
What does this mean for people who buy the new iPhone? Well, we&`&ll have to wait until it ships in November to find out what, exactly. But judging by my experience with Samsung&`&s OLED screens, I have a few guesses.
OLED screens paint a much more vivid picture, and the display is so bright and captivating that it almost doesn&`&t look real. You feel as if you could climb into the screen - it&`&s that immersive. For anyone who wears glasses or contacts, the difference between OLED and LCD screens feels like your prescription getting bumped up a notch and everything coming into sharper focus.
Battery Size
Last week at the launch Apple waxed lyrical about the class leading efficiency of its new A11 Bionic chipset which is at the heart of the iPhone 8, iPhone 8 Plus and iPhone X. A standout figure was that the A11 is 70% more efficient while idle than the A10 in the iPhone 7 and iPhone 7 Plus.
But go to Apple’s own comparison page and the company simply lists these new, more efficient iPhones as having identical battery life to their more inefficient predecessors. Why? Because it has just been confirmed Apple used the A11 Bionic’s efficiency as an opportunity to fit both the iPhone 8 and iPhone 8 Plus with smaller batteries.
The big shock is the iPhone 8 Plus which is fitted with a 2,675 mAh battery - the smallest capacity ever seen in the Plus range and over 8% smaller than the battery in the iPhone 7 Plus. Meanwhile the iPhone 8 has a 1,821 mAh battery which is over 7% smaller than the iPhone 7. The iPhone X battery capacity is currently unknown.
Wasn’t removing the headphone jack meant to result in larger batteries? The iPhone 6 and iPhone 6 Plus - which both featured a headphone jack - had battery capacities of 1810 mAh and 2900 mAh respectively. Meanwhile the Galaxy S8 has a 5.8-inch display in a chassis substantially smaller than the iPhone 8 Plus, fits a headphone jack, IP68 water resistance, fast wired and fast wireless charging and has a 3000 mAh battery…
Brightness
While the world applauded Apple’s jump not only to 5.8-inches, but also for the long awaited shift to OLED what was missed is a key detail about the display itself. The brightness is far from class leading.
While the world applauded Apple’s jump not only to 5.8-inches, but also for the long awaited shift to OLED what was missed is a key detail about the display itself. The brightness is far from class leading.
Look carefully on the iPhone X’s official spec page and you will notice right at the bottom of the screen specifications is the brightness listed as “625 cd/m2 max brightness (typical)”. Not only is this nits rating no better than the LCD-based iPhone 8 and iPhone 8 Plus, but it is demolished by pretty Apple’s biggest rival.
Displays of the five month old Galaxy S8 and Galaxy S8 Plus deliver 1,000 nits while the Galaxy Note 8 almost doubles the iPhone X with 1,200 nits. And who made the iPhone X display? Samsung.
Of course brightness is not the only measure of a display, but it is crucial for outdoor readability (HMD’s first Nokia-branded flagship the ‘Nokia 8’ manages 700 nits) so the iPhone X’s rating is something of a surprise - especially given who made it.
no longer the only choice
The iPhone X also introduces an awkward problem for the iPhone line. When Steve Jobs’ first smartphone was launched it was a ‘do everything’ single device. There were no features that were held back for a ‘better smartphone’. The buying choice was simple and in the face of multiple competing handsets with different options, some had GPS and mapping, some had good cameras, some had 3.5mm stereo jacks for listening to music. Part of the revolutionary nature of the iPhone was ‘this is all you need’.
That is no longer the case. Apple’s iPhone range now goes from the diminutive iPhone SE all the way up to the incoming iPhone X, a spread of five generations of devices. It’s a dizzying array of handsets where features may or may not be present, such as 3D Touch or Touch ID, different storage options at different price points, a riot of colors, the 3.5mm headphone jack, wireless charging, and facial recognition.
Now it takes a ridiculous amount of research and comparison to find the iPhone that may suit your needs, and there is not a single device that offers all of features in a single package – every iPhone has some form of limitation and restriction designed into it.
