Apple iPhone 6 review: One of the best smartphones available right now



Price

53500..
 With the iPhone 6, Apple has finally addressed the need for a larger screen on its smartphones. To many, this may look as if Apple is playing catch up with Android – it’s difficult not to, considering the stark similarities in the latest iPhone and Android (*cough* *cough* Samsung) devices both in terms of hardware design and software. Irrespective of what critics think, Apple continues to enjoy a huge fan following and its latest iPhones have only added to those numbers.
The iPhone 6 is the smaller of the two models launched this year, which sports a 4.7-inch display. The iPhone 6 Plus, sports a larger 5.5-inch display for those who need that extra real estate for getting work done. Apart from the larger screen, the iPhone 6 is quite similar to its elder sibling including the design and features.
The 4.7-inch Apple iPhone 6 comes with nifty improvements with a price to match, but is it the right smartphone for you? Read our detailed review to find out.
Design and build: 8/10


One of the biggest changes Apple has given to the latest iPhone is perhaps the design overhaul, which now makes room for a larger screen and marks its move from the straight-edged design. The iPhone 6 is great to look at given the sleek, fully-metal body design and edge-to-edge glass. At first glance, it could easily pass of as one of Android’s many candy-bar shaped devices from Samsung or HTC.

The iPhone 6 features an edge-to-edge glass design with 4.7-inch display
The 4.7-inch screen is easy to get used to and, thanks to the edge-to-edge glass design, the iPhone 6 manages to fit a larger display without increasing the width of the overall phone by too many inches. The phone still manages to fit inside pockets, though they don’t fit as snugly in the hands as the dinkier iPhones. We like the slim bezels on both sides.
We are not sticklers for diminutive screen sizes; in fact, it’s refreshing to see the iPhone finally come with a larger screen, as typing, reading and web browsing is a lot easier now. The screen size should be adequate for most people, but if you are used to a large “phablet”, the iPhone 6 Plus might be a better option.

The all-metal design looks fabulous, though you may miss the the more solid iPhone 5s’ look and feel
It’s really thin at just 6.9 mm and feels great to use – if a little slippery because of the curved edges. As with most super-thin phones, the camera of the iPhone 6 protrudes out slightly and there’s a ring to protect it. This means the phone does not sit evenly on its back. While the phone is still all metal, the iPhone 6’s body feels flimsier in comparison with the iPhone 5s. This could be a result of Apple trying to reduce the weight of the device.
The button to lock the display has now been moved from the top to the right edge of the phone, so that your fingers don’t have to reach out too far. The volume buttons are recessed and the ringer switch is now smaller to make the phone look as skinny as possible. It’s also lighter now, which you may or may not like.
Unlike other flagships, such as Samsung Galaxy S5 and Sony Xperia Z3, the Apple iPhone 6 does not come with rugged features such as water-proofing and dust-proofing.
Features: 7/10
The Apple iPhone 6 houses the Apple A8 system-on-chip which is backed with 1GB of RAM. The Apple A8 SoC is based on the 20nm manufacturing process and houses a dual core Cyclone ARMv8 processor with support for 64-bit OS. It has Imagination’s PowerVR GX6450 GPU. The 16GB version comes with around 11.5GB of free space for saving apps, music, photos and other downloads.
The 8MP iSight camera comes with a dual LED flash and improved optics for better low-light photography and action photography. Also, you can now capture photos and videos simultaneously. Note that with iOS 8, you can integrate additional photo-editing apps to the default Photos app. Learn about more iOS 8 features here.

The iPhone 6 comes with improved camera features
The camera now has a slow-motion mode, which lets you capture videos at either 120 frames per second or 240 frames per second. In addition, iOS 8 adds the time-lapse feature that lets you get creative with your videos. And then there’s the usual panorama mode and the ability to focus specific areas by touching the screen.
iphone 6 fingerprint scanner
All connections are placed at the bottom, as with all iPhones
Like the iPhone 5s, the fingerprint scanner works well and is useful for quickly unlocking the screen and authorising payments on the App Store. The latest iPhone comes with Apple Pay for cashless payments, though the service is not available in India yet.
Software: 9/10
As with most Apple devices, the iPhone 6 is extremely easy to use, even if you are a first-time iOS user. The iPhone 6 comes with iOS 8, which you can update to iOS 8.1. While some users have reported issues with the new update, we had no trouble with the device we tested. iOS 8 lets you add widgets on the notification screen, install third-party keyboards and with features called Handoff and Continuity, you can take off from where you left on another Apple device. This means, if you started a game on the phone, you can finish it on an iPad, or if you are working on a document on a Mac or iPad, you can carry on with the same on your phone. This worked well when we tried it, though you will need to have a common iCloud account set up on all the devices to make use of this feature.

With Reachability features, you can bring down the screen by double-tapping the home button. This helps if you are not used to a large-screen phone, so you don’t have to stretch your fingers too far when using apps.
Performance: 9/10


The device runs smoothly and can even take on heavy app use and graphic-heavy games. However, the phone tends to get noticeably warm on intensive use. This could affect the battery life during the course of time, unless Apple rectifies this in its future iOS updates.
The iPhone 6 maxed out in the 3D Mark benchmark test, while the AnTuTu benchmark test showed that it is faster than the iPad Air and considerably faster than the iPhone 5s, though you can’t really tell the difference in regular use case scenarios.

In terms of processing speed, the iPhone 6 is quite a stunner
Call quality is excellent whether you are receiving or making calls.
If you are already an iOS user, there’s little you’ll need to adapt to in terms of getting media on to your device. With the iOS 8 update, you can now delete songs and create playlists directly from the app, without having to connect it to your computer. You can transfer songs and movies by installing the iTunes app on your Mac or PC. Once connected over Wi-Fi or via the microUSB slot, you can quickly sync apps, transfer music and videos or create backups on iCloud. You can also download movies, songs and music albums from Apple’s comprehensive iTunes Store after creating an iTunes account.
You get the same set of Apple’s signature Earpods that are designed to fit perfectly in your ears. Sound quality is very good compared with most earphones that are supplied with mobile phones. You can always switch to your own good pair of headphones with the 3.5mm headphone jack. There’s no FM radio and iTunes radio is not available in India.

The iPhone packs all the necessary accessories – a USB charger, headphones and a quick start guide
The iPhone 6 supports all modern frequencies and connectivity options including 4G LTE. There’s support for NFC, but only for making purchases via Apple Pay.
Display: 9/10
WP_20141029_13_44_53_Pro
The iPhone 6’s Retina HD display produces crisp images and text
Apple has spruced up the resolution in the iPhone 6 going from 1136×640 on the iPhone 5s to 1334×750 on the iPhone 6, but the pixel density is the same at 326ppi as the screen is now larger. It looks fantastic nevertheless and images and text look very sharp. Apple has included some not-so-obvious changes to the display – it’s now less reflective under bright light, has a shatter-proof glass and an oleophobic coating to minimise fingerprints.
Camera: 9/10
The iPhone 6’s 8MP iSight camera comes with some nice improvements from its predecessor. While the resolution is similar to the iPhone 5s, you get a major boost in the autofocus department. The iPhone 6 supports phase detect pixels which help in faster AF acquisition. You can now adjust the exposure while shooting, focus faster for capturing fast-moving objects and take better low-light photos. You can also lock the auto focus and auto exposure of a specific area by holding your finger on the screen for a moment. This is very helpful in instances when taking a picture in bright light where you need to mange shadows.

The iPhone 6’s camera is among the best we’ve seen on a smartphone. Not only is it really fast at capturing photos, but it’s also accurate with colours and come out crisp and detailed, especially in bright outdoors.
Outdoor landscape

It’s great for taking low-light shots, too. Noise levels are well controlled even in shots taken in the dark, and the camera focusses quickly and accurately enough most of the time. This makes it great for capturing blur-free, fleeting moments.

While the main camera has been updated, there’s no big improvement in the front camera. Self-shots taken from the 1.2MP front camera appear quite pixillated and colours look slightly smeared. However, compared with the 5s, it does tend to do a better job at taking selfies in dim light. In addition you get more control over selfies, as you can now adjust the exposure, time your clicks or take multiple self-shots by holding down on the shutter button.

Battery life: 7/10

There iPhone 6 packs a 1,810mAh battery, which may seem paltry compared with other phones in its league. However, its battery life is above average, if not the best in its class.
In our tests, the iPhone 6 managed 14 hours of calls on the 3G network with the auto-brightness set on and location access switched off. When left on standby, it managed nearly six days without charging with mobile data and location access switched on.
On average use,which consisted of about an hour of calls, moderate web browsing and app use (WhatsApp, Facebook, Messages and Music), the phone lasted for a full day and a few more hours before we had to plug it back to the mains. While these are not outstanding results, it should be able to get you through at least 12 hours of heavy smartphone use.
Location access for apps eats up your battery faster when switched on.We recommend turning it off when you don’t need it. Alternatively, you can switch off location access for specific apps from the settings app.

Verdict and Price
The iPhone 6 starts at Rs 53,500, which is around the same price at which the iPhone 5s was launched last year. Considering the limited storage and the fact that you can’t expand the memory with a memory card, the price may be a deal breaker for many.
Apart from that, the iPhone 6 surpasses most areas, which makes it one of the best smartphones you can buy right now. It has a brilliant display, one of the best cameras you’ll find on a smartphone, excellent call sound quality and it’s super-fast to use. It’s definitely the best iPhone you can buy, but if you don’t mind the massive screen, you may like the iPhone 6 Plus more.
On the downside, the iPhone 6 lacks in features compared with rivals. For example, it’s not waterproof, you can’t expand the storage and you can’t use NFC for transferring data. Also, despite the improvements in iOS 8, it’s sill not as flexible as Android. If these are things that matter to you, consider other alternatives such as the Galaxy S5 or the LG G3.
If you are already an iPhone user and are unhappy with the screen size, the iPhone 6 is worth the upgrade. But iPhone 5s users, in particular, won’t find much of a conceivable difference in terms of the overall performance.
 

10 tricks in Apple’s iOS 8 that you probably didn’t know


10 tricks in Apple’s iOS 8 that you probably didn’t know


If you’ve recently upgraded to iOS 8, you’ll find no major changes in the look and feel in the latest version of Apple’s mobile OS. The interface is exactly the same as iOS 7, while some new apps have always existed on iOS devices. Why then are so many people swearing by the new update? The truth is, many features have been added in the most unassuming fashion that take some rummaging to find. Save yourself the time and effort as we reveal some of the coolest features you may not have noticed yet.
 
1. Add shortcuts on your notification screen
Notification center
With support for a variety of widgets, you can gain quick access to often-used functions just by pulling down the notification screen. Widget apps such as Launcher, Quick-Tap and Wedge give you on-tap access to your favorite contacts, music and apps. Once you’ve selected which shortcuts you need from the app, Select Edit on the Notification Center and simply click on the green “+” button next to the widget’s name.
2. Say “Hey Siri” to use it handsfree
hey siri
To open Apple’s voice-assistant Siri without using your hands, just say “Hey Siri”. However, this works only if your phone is plugged to a power source. So if you’ll be using it while driving, you’ll have to first plug your iOS 8 device to the car battery. To enable this feature go to Settings | General | Siri and toggle Allow “Hey Siri”.
3. Snap a photo to add a credit card
add credit card
To make online purchases faster, click a photo of your credit card to save the card details on your iOS 8 device. To do this, go to Safari settings, select Passwords & Autofill and click on Saved Credit Cards. The Use Camera option lets to snap a picture of your card, which then automatically scans the card to pull out all your card details. If you’re shopping on a website, it’ll give you the option to scan a card by taking its photo. It detects the card number, expiry date and name, though you’ll still have to enter in the CCV number.
4. Add third-party editing tools to the built-in camera
Photo editing
Though iOS 8 comes with new editing features, some may still find them to be inadequate. With support for third-party apps, not only do you have features from different photography apps in one place, but you can also make changes as soon as you click a photo. Once you’ve chosen from iOS 8 supported photo-editing apps, you’ll see a tiny option on the top left of the screen after you take photo. Click on it to see all the apps in one place and edit photos from right inside the Photos app.
5. Raise to listen to voice iMessages
raise to listen
We know that Apple has added voice to iMessages for sending voice clips to a fellow Apple user. To listen to them, you can just lift your iPhone or iPad to your ear. To enable this feature, select Raise to Listen from Messages, under Settings.
6. Request desktop version of a website
Desktop site
Some mobile-optimised websites can can have several features missing from the desktop version. While some websites give you the option to switch to the desktop version, there are many that don’t. The Safari browser in iOS 8 lets you see the the desktop version using a simple trick. On the address bar, select the URL and scroll downwards to see the Request Desktop Site option.
7. Mark all messages and emails as read
read all
Often, there are emails and messages that you don’t intend to read, but are afraid of losing something important by deleting them. If seeing a too many unread emails or messages on your phone puts you off, a better option is to mark them as “read”. To make this easier, you can “mass read” all messages and emails by selecting Edit on the top right and selecting Read All at the bottom-left of the screen.
8. Find which apps have been hogging your battery the most
Battery usage
Now you can see how much power each installed app consumes. Not just that, iOS 8 will also show you the reason why an app consumed a certain amount of battery. For example, apps running in the background say “Background activity”.
9.  Recover deleted apps
Recently deleted
To recover photos or videos that have been accidentally deleted, there’s a new folder called Recently Deleted. This includes recently deleted apps which you can recover if you need to. Older photos and videos get deleted automatically from the folder.
10. Invert colours to read in the dark

Google kickstarts GOSF 2014 pre-party today, online festival to be held from 11th to 12th December


http://www.thegosf.com/wp-content/uploads/2014/02/gosf-2014.png
 If you are about to buy yourself some new clothes, electronics or household items, hold your horses as Google India has announced the Great Online Shopping Festival (GOSF) for 2014.

For those who don’t know, GOSF brings together several online retailers across India to offer discounts on their products. The initiative was launched by Google in 2012 to boost the adoption of online shopping in India. Rajan Anandan, VP & Managing Director, Google India, said, “Great Online Shopping Festival is India’s version of cyber Monday in the West and is an exciting platform to raise awareness and consumer adoption of online shopping in India.”
Google has announced that the shopping festival will run between 10 – 12th December, which is just two weeks away. In addition, the GOSF website has announced a pre-party on November 25, as a prelude to the actual shopping festival.
Several websites, including Snapdeal, FabFunish and FirstCry have geared up for the GOSF sale. Coupon Dunia has already listed GOSF shopping coupons for different shopping websites, while DesiDime has created a special section for GOSF on its website, which lets users see all GOSF deals in one place.
Last year, though the festival attracted lots of interest, it met with several road blocks. Less than an hour after the festival went live, the site went down due to a technical error. Google then had to extend the festival by another day. Hopefully, the GOSF team will be better armed this time to run the festival smoothly.
GOSF aims to bring more Indians onto the web, while also boosting sales of various online portals. Google itself has a lot to gain through the GOSF sale. As reported by NextBigWhat, Google India’s revenues have skyrocketted by 48% over last year. As the festival attracts hordes of new online shoppers, Google stands to benefit with the multitude of advertisements and marketing campaigns launched by e-commerce portals.
According to the NextBigWhat, “Google makes no money out of GOSF, but through the entire year, they probably make more money than Ecommerce portals.”

Google reaches settlement with ex-Morgan Stanley banker over online abuse charges


https://www.google.com/doodle4google/images/splashes/featured.png 
Google has agreed to a settlement with a former Morgan Stanley banker who sued the search engine over defamatory Internet posts.
Daniel Hegglin, a Hong Kong-based investor, went to Britain’s High Court to force Google to ensure posts falsely labeling him a murderer, pedophile and Nazi didn’t appear in search results.
Hegglin’s lawyer, Hugh Tomlinson, said Monday that the case had been settled. He didn’t disclose details, but said the settlement “includes significant efforts on Google’s part to remove the abusive material” from search results and Google-hosted websites.
http://fc02.deviantart.net/fs70/f/2013/189/7/f/simple_rainbow_google_logo__install_guide___by_thepatrollpl-d6ci0lz.png
Google lawyer Antony White said the company was sympathetic to Hegglin, who had received an “exceptional” amount of Internet abuse. He said Google wasn’t responsible for policing the Web, but would “continue to apply its procedures that have been developed to assist with the removal of content which breaches applicable local laws.”
Hegglin’s case is separate from the European Court of Justice’s “right to be forgotten” ruling, which allows people in 32 European countries to ask Google to delete material that unfairly tarnishes their reputation.
Google said last month it had received 145,000 requests to remove search results since the court ruling in May.
 

Sony Pictures hacked, corporate systems forced to shut down


http://media2.intoday.in/btmt/images/stories/sony_660_082514123202.jpg 
 Sony Pictures has reportedly been hacked and their entire computer system is unusable, compelling people to shut their computers and disable Wi-Fi on all mobile devices.
A thread appeared on Reddit posted a year ago, regarding Sony Pictures, which had an image that surfaced on all employee’s computers reading, “Hacked by #GOP”. The message followed was,
“We’ve already warned you, and this is just a beginning. We continue till our request be met. We’ve obtained all your Internal data, Including your secrets and top secrets. If you don’t obey us, we’ll release data shown below to the world. Determine what will you do till November the 24th, 11:00 PM (GMT).”
The Next Web said that the ZIP files mentioned in the images contain a list of file names of a number of documents pertaining to financial records along with private keys for access to servers. The message shown on computers mentions “demands” that must be met by November 24th at 11:00PM GMT or the files named will be released.
A source within the company admits that the hack inside Sony Pictures is very much real and starting spreading widely when a single server was compromised.
Sony Rumors also pointed out that the company’s response to the matter was, “We are investigating an IT matter.”

Researchers hope achieve Internet speeds of up to 10Gbps using 5G networks


http://static.digit.in/default/artImg198x166_17341.jpg?v=1 
Researchers are investigating how software-defined cellular networking might be used to give smartphone users the next generation of  ultra fast broadband – 5G.
Currently, the fourth generation of mobile phone connection technology, 4G, in as far as it has been adopted provides broadband-type connectivity for enabled devices such as smartphones, tablet computers, laptops and other gadgets through two standards: the Mobile WiMAX standard and the first-release Long Term Evolution (LTE) standard.
Peak speeds were set in the standards at 100 megabits per second (Mbit/s) for mobile users and ten times that for static, domestic 5G users, 1 gigabit per second. 100 Mbits/s is three times faster than the earlier 3G system but users commonly do not see data transfer at such high rates, downloads are usually at best 10 Mbits/s. As yet, there is no single standard for 5G although various systems are being touted based on rebuilding the cellular networks to be super-efficient and exploiting different frequencies with their capacity for greater data rates.
The hope is to be able to achieve download speeds of perhaps 10 Gbits/s, researchers said. In practice, this means that a high-definition movie can be downloaded in less than half an hour. The research is being undertaken by Ming Lei of Samsung Research and Development Institute China, Lei Jiang of NEC Laboratories, Beijing with colleagues at the University of Electronic Science and Technology of China in Chengdu, Beijing Jiaotong University and the University of Kurdistan.
They have assessed the latest developments aimed at 5G systems and have proposed their own novel end-to-end (E2E) software-defined cellular network (SDCN) architecture which
they say offers flexibility, scalability, agility and efficiency.
Moreover, it will be sustainable for providers as well as profitable, researchers said. They are currently building a demonstration system that will allow them to utilise several promising technologies in their architecture for 5G including cloud computing, network virtualisation, network functions virtualisation and dynamic service chaining.
The approach, they suggest, could overcome bandwidth shortage problems, improve quality of service so avoiding delays and data loss, as well as reducing the vast number of error-prone network nodes needed for such a system. The research was published in the International Journal of Communication Networks and Distributed Systems.

Xiaomi Redmi Note registrations begin today: Here is all you need to know


http://4.bp.blogspot.com/-knoECbE7qEc/UwRfLWjkFHI/AAAAAAAAAsE/8udj7Ji3G8c/s1600/Front+angle+red.png

Xiaomi has been wooing audiences with its ‘value for money’ products and unique flash sales in which devices fly off the shelves in seconds. After the popular Mi 3 and best selling Redmi 1s, the company is now gearing up to launch the Xiaomi Redmi Note in India which will be available to users soon.

It was Hugo Barra who spilled the beans about Note coming to India soon, and later Xiaomi India head, hat the device will come to India in December. Without wasting much time, the company quickly came up with a contest on Facebook, further hinting that the Redmi Note is on the way.

The Redmi Note has finally launched in India and will be available in two variants: 3G dual-SIM, priced at Rs 8999, and a 4G variant priced at Rs 9,999. In an exclusive tie-up with Airtel, the 4G variant will sell in select Airtel retail stores.

Flipkart has confirmed that registrations for the Redmi Note will open today at 6pm and the phone will be launched on December 2 as expected.

Before you part with your cash, here’s all you need to know about the latest Xiaomi phablet.
Design and Display
With the Redmi Note, Xiaomi plans to bring large screen experience on a budget for audiences. The sub-Rs 10,000 device sports a large 5.5-inch HD display with 720 x 1280 pixels of resolution, and a pixel density that goes all the way up to 267 ppi.
Weighing 199 grams, it is slightly heavier than other popular devices that come with a 5.5-inch display. The plastic -built device measures 154 x 78.7 x 9.5 mm. It comes with a removable cover that can be swapped with other designs, but we wonder if these covers will be made available in India.

10 Things Android Lollipop can do but Android KitKat cannot

http://cdn1.knowyourmobile.com/sites/knowyourmobilecom/files/styles/gallery_wide/public/Array/android-l-vs-android-kitkat.jpg?itok=TftaiwJi
Android kit kat vs lollipop
We might have not been this excited as children to have a candy lollipop as much as we are to have the latest Android 5.0 Lollipop update installed on to our devices.
The time finally arrived when our Android OS would get a quick makeover and offer us with either some simple; or extravagant changes. But are these changes going to make our lives easier? Is Lollipop far advanced than KitKat? We check out some of the prominent changes that have been brought about in the latest update.
1. Inbuilt Flashlight
It would always be puzzling as to why Google did not pin a flashlight in our notifications panel just like iOS has in its control center. Lollipop brings out that change. Without installing any third-party apps, users can simply use the flashlight by pulling down the notification panel. Make sure your smartphone has an LED flash.
2. Battery changes
Battery seems to be given priority in Android Lollipop. No longer do users have to lay bets on how long their battery would last for. The new OS has two new and much needed features which were not available on KitKat. It shows you how long it would take to charge your phone and a small  showcasing how much time is left before the battery runs out. After you have plugged in your phone for charge, your home screen will show you the time until full charge.
3. Guest user
We all have people around us who lay their hands on our phones. Thankfully, Android Lollipop helps us with this issue. Just like different Users in Windows, Lollipop gives you the liberty to add guest users or even create a profile for a friend/relative. This way, you can limit the amount of information that others can view. You can add a guest by simply going to Settings – Users – Add Guest.
4. Flappy Bird easter egg
If Flappy Bird wasn’t frustrating, Lollipop offers you a modified version of the game. Instead, here you have an Easter egg to unlock. Users can go to Settings – About phone and click several times and you will get the android robot in place of the bird.
 5. Notification panel
Needless to say, the notification panel has been made too simple for the user. It’s simplicity in design is the plus point. Unlike KitKat, the most useful feature added here is the ability to view your detailed notifications on your lock screen. Though this might be a problem around work spaces if you leave your phone unattended, anyone can have a look at your notifications even though your phone is locked. It can be disabled by going to Settings – Sound and Notification – When device is Locked – Don’t show notifications at all.

Android lollipop 5.0
6. Trusted Places
Trusted Places is a smart feature which has been added in to Lollipop. Though most of our phones have passwords, it would be a task to disable it when we enter familiar premises such as our car or home. Trusted Places is a feature where a user can declare certain locations as safe and they wouldn’t need to unlock their phones once they enter those spaces. You can set the location by heading to Settings – Security – Smart Lock.
7. Soft key redesign
Soft key buttons receive a change in this update and it is a rather, a surprising change. The icons are smaller and look compact. A very simple yet pleasant design.
8. Multitasking 
Multitasking has completely changed in Android Lollipop. The feature allows you to scroll through your notifications in a simpler manner. It is easier and allows you to see more details even before you enter the app.
9. Prioritize apps
It can be super annoying if your phone is filled with umpteen apps and throughout the day, you are bombarded with notifications. Lollipop gives you the liberty to prioritize your apps so that you can receive notifications from the ones you want. It works out perfectly during sleep hours as you can only receive notifications from important apps and not games or check-in notifications.
10. Quick access to Chromecast   
No need to install any third-party apps once you have the updated your phone to Lollipop. There is an official app now from Google to solve our problems. For the people who love to stream media from dongles, it is as simple as going to the notification panel and taping on Cast Screen.
