iphone 5 review

The Apple iPhone 5 is finally here, with the latest arrival boasting a 16:9, 4-inch screen, new smaller port, thinner, lighter design and 4G LTE.The iPhone 5 was possibly the most anticipated electronics product in history.
For months before its release, every nuance and design decision (whether real or not) was picked apart online.
However, last week Apple unveiled the iPhone 5, and on Friday, it goes on sale in the US and UK, along with several other countries, having already notched up a record setting 2 million preorders in just 24 hours.
The iPhone 5 is a marvellous piece of design, arguably the most beautiful object Apple has ever produced. In the five years since the first iPhone, Apple’s smartphones have taken the company’s value sky-high, and made it a star.


Apple has made the iPhone 5 taller than the iPhone 4S but no wider, thankfully, in portrait orientation. That's helpful because as smartphones have gradually got bigger and wider, my hands have stubbornly remained the same size.The Gorilla Glass back of the last iPhone is gone, replaced with metal. The two-tone look might seem new, but it's a bit of a reference to the silver-and-black back of the original iPhone.The very top and bottom of the rear is still glass. That anodized aluminum  which Apple claims is the same as that on its MacBook laptops  feels exactly the same, and is even shaded the same on the white model.The iPhone 5's 3.95-ounce weight is the lightest an iPhone's ever been. The iPhone 4S is nearly a full ounce heavier at 4.9 ounces. The iPhone 3G was 4.7 ounces.
The new display measures four inches from corner to corner, compared with the 3.5-inches of previous iPhones. Since the phone is not wider, that gives the iPhone 5 a screen resolution of 1136-by-640 pixels, compared with 960-by-640. Held in landscape orientation, the iPhone 5 screen can now display a 16:9 film without black bars at the top and bottom.Viewing angles are incredibly broad – you can sit entirely offside from the iPhone 5 and still see the display with no color inversions – and the pared-down construction means the overall screen assembly is thinner and thus the iPhone 5 as a whole can be slimmer.
The screen on the iPhone 4S was impressive but the new one looks better. It's brighter and the colours are richer. Initially, the extra screen size will means black bars around apps because existing iPhone apps will display at 960-by-640 until developers update them. Expect a rush of app updates starting this week.
The display may be bigger but so is the resolution, so Apple’s Retina boast carries over from the iPhone 4S. Higher resolution panels are proliferating across the top-tier smartphones, but the iPhone 5′s 326ppi pixel density means individual dots are still all but invisible to the naked eye. The in-cell touchscreen has also left the panel clearer in direct and indirect sunlight, a real advantage when you’re using the smartphone outdoors.


Apple says the iPhone 5 will be up to twice as fast, thanks to its new A6 processor. Each iPhone version has been faster than the one before.Apple’s A6 processor, billed as being twice as fast as the A5 inside the iPhone 4S, is based on ARM’s dual-core Cortex-A15 chip. Manufactured by Samsung in Austin, Texas, it is the same basic processor as used in the Galaxy S3.


The iPhone 5 finally adopts faster LTE, joining most other smartphones on the market and even the third-gen iPad, with the leap to LTE back in March. However, the presence of LTE doesn't mean a world LTE phone; currently, LTE roaming between carriers overseas is impossible.The iPhone 5's LTE uses a single chip for voice and data, a single radio chip, and a "dynamic antenna" that will switch connections between different networks automatically.
In the United States, AT&T, Sprint, and Verizon Wireless will carry the iPhone 5.In Canada, it's Rogers, Bell, Telus, Fido, Virgin, and Koodo. In Asia, the providers will be SoftBank, SmarTone, SingTel, and SK Telecom. For Australia there's Telstra, Optus, and Virgin Mobile, and in Europe it will go to Deutsche Telekom and EE. On carriers without LTE, the iPhone 5 will run on dual-band 3.5G HDPA+. Nevertheless, data access via 4G LTE is stunningly fast.


The iphone 5 has a 8-megapixel iSight camera. The resolution may be the same as before, but the combination of a new backside-illuminated sensor and a reworked lens – covered with a tough sapphire crystal glass – along with new software and processing, add up to stills and video a step above what the iPhone 4S can deliver. It's still an 8-megapixel camera, but there's a new sapphire-crystal lens, and improved hardware enabling features like dynamic low-lighting adjustment, image stabilization on the 1080p video camera, and the capability to take still shots while shooting video.The new iSight camera takes pictures faster than the iPhone 4S, which already took pictures faster than the iPhone 4. Snaps are lightning-quick.
The "Panorama" camera functionality is truly remarkable. Start moving the camera, take a picture, and it will keep going until you have a 28MP scene. Yes, other cameras have had panorama systems – including, Samsung. Those limit you to staying in one place and moving the camera around. This is different: you can move yourself, you can move around or up and down and object, or whirl completely around – 360 degrees of freedom. Then once you're done, the software stitches it together, with no fisheye distortion and no stitching. I tried circumnavigating a colleague's head, and whirling the phone around in a field: the results are really interesting.Still pictures taken while recording video aren't shot using the normal 8-megapixel Webcam; they're screen captures of the video itself. The aspect ratio is different, and the image quality's a bit weaker.The iPhone 5 gets a rear camera capable of 1080p video recording, during which you can also shoot stills. The front-facing camera gets 720p recording, and FaceTime – Apple's video call protocol – works on both Wi-Fi and mobile

iOS 6

Maps and Siri are probably the biggest points of change. Google Maps is gone, replaced by an app of Apple’s own development,The maps don't have all the highlighting of Google's, but the amount of detail such as road names seems to be greater. The 3D view  is entertaining – more so if you turn on the satellite imagery – and you can also rotate the maps with two fingers, or bring them back to true north by tapping a compass.
2D and 3D mapping, along with photo-realistic flyover views, all look great on the 4-inch Retina display, and there’s no lag when swiping around, rotating the map, or zooming in and out.
Apple has embedded traffic alerts into its app too, so turn-by-turn navigation – with spoken prompts, naturally – takes into account the actual road conditions rather than just the basic speed limits, when it figures out your ETA. That data can also be used to prompt detours if Maps figures out there’s a delay ahead.
Unfortunately, it’s not perfect. The excellent mass transit mode in Google Maps has no counterpart in Apple Maps, so there’s no way to plan journeys that include bus, train, or other public transportation.
But, there are absences  Google Street View is gone, because this isn't an app powered by Google anymore. Flyovers take the place of Street View to some degree, but flyovers are only available in large cities, and not all of them.


In its new incarnation, Siri can find and book restaurants , tell you football scores, offer turn-by-turn navigation to anywhere, open apps,post comments to Twitter or Facebook, and find film times and reviews. It does other stuff too including weather forecasts and stock prices.


iOS6 introduces the idea of Do Not Disturb – times between which you don't want phone calls or notifications such as texts to bother you, although you can elect to let those numbers picked as "Favourites" through at once, and determined callers on the second call.Similarly, when someone calls and you can't respond, you get a choice of rejecting the call, or sending a pre-prepared text message from a selection, or creating one on the spot – all from the lock screen if needed.HTC and Samsung have offered this already


Passbook is interesting. Retailers and businesses will need to sign up – for free, apparently – but once on board, you’ll be able to download flights, tickets, vouchers etc from them and store them in a digital wallet.


Apple promises 8 hours of 3G talk time, 8 hours of 3G browsing, 8 hours of LTE browsing, 10 hours of Wi-Fi browsing, 10 hours of video playback, 40 hours of music playback, and 225 hours of standby time with the iPhone 5.In practice, with heavy use of both LTE and WiFi, push email turned on, media playback and streaming, some browsing and Maps use with GPS, and iCloud sync active,The battery lived for more than 5hrs and more than 7hrs on standby.


The Lightning connector is a miniaturized, reversible charge and sync cable that works with USB 2.0, nothing more. It was designed to be reversible and easy to insert and remove. It is. It was designed to be smaller and take up less space.That eight-pin Lightning port won't work with USB 3.0 or Thunderbolt, or even Micro-USB, an existing standard for tiny charge/sync ports that Apple's wilfully disregarded. It's proprietary, like the original 30-pin port on existing iPhones, iPods, and iPads. The Lightning port's easy to use, and easier to plug in, than the 30-pin.


Specificationists will say that with the iPhone 5 Apple is now behind its rivals in terms of features.But don`t underestimate it because it can do a lot of work better than android devices.Siri is much more accurate than S voice,the build quality is great as compered to it`s rivals.So if you are looking for an upgrade to your 4s this is a great deal.
