iPhone 4 - 32GB - iOS 4.3 Complete Review

iPhone 4 is not just a piece of mobile hardware from Apple, it creates ripple effect in the mobile phone market when there is a new piece of mobile hardware from Apple. The iPhone-4 is certainly no exception with with features like a super-fast A4 CPU, a new front-facing camera and five megapixel camera with HD Video Recording on the back, a completely new industrial design, and that outrageous Retina Display with glossy glass finish, Multitasking, Video Chat and so on..

Hardware

It's not just the face of the phone that's undergone a transformation -- the iPhone 4 is all new inside as well. For starters, Apple has moved on from the Samsung-built ARM Cortex-A8-based CPU used in the 3GS to its custom A4 chip used in the iPad, which funnily enough... is an ARM Cortex-A8-based CPU. While the company hasn't yet said what the clock speed of the processor is, we're guessing it's something below the 1GHz touted for its tablet cousin. The phone is definitely snappier than the 3GS, so we're not about to volley complaints in particular, graphics seemed to render faster, and overall responsiveness it slightly higher, though admittedly, it isnt blowing the doors off the joint. It's certainly faster, but the 3GS wasn't hurting on speed to our eyes, so it's not as wildly noticeable a leap as the 3G to the 3GS.

As usual, Apple isn't fessing up about the RAM situation, though we have on very good authority that the iPhone 4 has 512MB onboard, a big step up from the 256MB in the previous model and the iPad. We would have liked to see it futureproofed with something like 1GB, but then again, Apple's got to sell a new phone in a year. As far as internal storage goes, you can buy the new iPhone in either 16GB or 32GB capacity -- fine for now, but since the company has just introduced 30FPS 720p video recording, you could find yourself outgrowing that number pretty quickly. It's a little odd, in fact, that the company didn't double down here and bump the capacity to 64GB, as it's recently done with the iPod touch. In terms of wireless, the iPhone 4 is packed with an 802.11n WiFi radio, as well as a quad-band HSUPA chip and Bluetooth 2.1.

The redesigned housing allows for a much larger lithium-ion battery on the inside, providing improved numbers for Apple's life ratings (more on that in a moment), though it's still not easily replaceable. Additionally, the new phone has those two new cameras (VGA up front, five megapixels with LED flash around back), a new second microphone used to combat background noise while on calls (similar to the Nexus One), a gyroscope in addition to the standard accelerometer, a light sensor, and a proximity sensor. As with the 3GS, an AGPS chip and compass are bundled somewhere in that tiny frame as well.

The big internal story is what has become external: namely, the UMTS, GPS, WiFi, and Bluetooth antennas. Apple has made the stainless band around the phone essentially a couple of big antennae, and they seem to be doing a pretty good job at hanging onto radio signals. The big question is obviously whether or not this fixes or helps with the constant dropped calls iPhone users on AT&T's network have gotten used to. Well in our testing, we had far, far fewer dropped calls than we experienced on our 3GS. Let's just say that again: yes, the iPhone 4 does seem to alleviate the dropped call issue. It wasn't perfect, and we had some connection issues in downtown New York City in particular, though it's tough to say if it was the fault of our phone, the cluster of buildings we were near, or the person we were speaking to, who was on a 3GS in the same location.

Design

the design of the iPhone 4 to that of a "beautiful, old Leica camera," and as we've said before, he wasn't off the mark. Instead of hewing to the curved, plasticky, silver-bezeled look of the iPhone 3G and 3GS, the company has turned the casing and face of the device into something decidedly more detailed and sophisticated. From the design aesthetic through to the actual build process, Jony Ive and his team have reset what we expect in an iPhone, coming up with something that clearly harkens back to the retro-future Braun designs of Dieter Rams. The iPhone 4 is made up of three basic parts: two pieces of smooth, strengthened glass, and a stainless steel band which wraps around the sides, top, and bottom of the phone. The effect is clean but not simple, and Apple has added little details, like altered volume buttons (what used to be a rocker is now separated into circular clickers labeled + and -), and notches in that metal band which serve to improve radio connections (more on that in a minute). The phone is noticeably thinner than the 3GS at .37 inches compared to .48 inches, but it weighs the same 4.8 ounces, making the whole package seem tighter and denser. It feels great in your hand, with good heft, although it might take a little time to get used to the lack of a rounded back if you're coming from the 3G or 3GS.

We can't overstate how high-end the design of the iPhone 4 is. The 3GS now feels cheap and chubby by comparison, and even a phone like the HTC Droid Incredible -- which just came out -- seems last-generation.

As we said, there are three main pieces of the phone, which together create an effect not wildly dissimilar to that of an ice cream sandwich. You know, but far pricier... and not edible. The face of the device is made up of extremely strong glass which Jony Ive says is "comparable in strength to sapphire crystal, but about 30 times harder than plastic." A small slit for the earpiece and the front-facing camera are embedded in the glass above the display, with the familiar home button towards the bottom -- a button we should note feels much clickier than on our 3GS. On the left side of the phone you've got the new volume buttons, a redesigned mute switch, and a small notch towards the base of the unit. On the right side is the Micro SIM slot and another notch in the band at the bottom, and up top there's the power / sleep button, headphone jack, another notch, and new noise-canceling microphone. Along the bottom is a speaker, microphone, and the 30-pin dock connector port. The backside of the phone is made from the same kind of ultra-strong glass as the front, interrupted only by the new five megapixel camera, its LED flash companion and, of course, the Apple logo.

Overall, the iPhone 4 outclasses pretty much every smartphone on the market in terms of industrial design.

Display

LED backlit, 960 x 640 IPS screen the "Retina Display"! Retina display’s pixel density is so high, your eye is unable to distinguish individual pixels. Which means Text in books, web pages, and email is crisp at any size. Images in games, movies, and photos pop off the screen. And everything is sharper.

Not only are the colors and blacks deep and rich, but you simply cannot see pixels on the screen. Okay, if you take some macro camera shots or get right up in there you can make them out.
Text rendering is incredibly clear and clean -- webpages that would be line after line of pixelated content when zoomed out on a 3GS (say,
any web sites) are completely readable on the iPhone 4, though the text is beyond microscopic. It's impressive, and doubly impressive when you look at higher-res graphics or watch 720p video on the phone -- the detail in moving images is particularly striking. What's nice is that most apps with text in them will benefit from this tech whether or not they've been updated, as long as they're using Apple's font rendering. Text in any app, for instance, looks cleaner, clearer, and much easier to read on the new iPhone.

Overall, you simply won't find a better display on a phone, and that's not just a lipword.

Cameras

The cameras on the new iPhone are going to be a topic of much debate, since this has been an area where Apple has been slow to innovate. The 3GS sported a measly three megapixel shooter with few bells and whistles (and no flash), and while it was fine for quick snaps, it wasn't an artist's tool by any means. The company finally seems to be listening to a public that's interested in leaving the point-and-shoot at home in favor of a phone with a capable camera, by adding a five megapixel shooter to the backside of the iPhone 4 and a VGA camera up front.

Let's first take a look at the higher-res main camera. At his WWDC keynote, Jobs said that getting great looking images wasn't just about upping the camera's megapixels, but had more to do with grabbing more photons. Increase the photon count, let more light in, and your images will look better, the thought goes. So Apple's using a newer backside-illuminated sensor that's more sensitive to light in addition to upping those megapixels -- and we must say, pictures on the iPhone 4 look stunning. Our shots looked good right out of the gate, with few problems when it came to focusing or low light. With the flash on, we managed decent if somewhat blown out results (fairly common with smaller LED flashes) though impressively, the iPhone 4 was usually able to take completely useable and even handsome photos in fairly low light without the flash. It seems like that photon situation is definitely in play, because even shots taken in fairly dark lighting came out looking good. Autofocus worked well in most situations, and we were actually able to get some impressive looking macro shots (see the flowers and Penny below). In general, we'd have no trouble using the iPhone 4's camera as a stand-in for a dedicated camera. Not only did it take beautiful shots, but the A4 and iOS 4 combo have considerably sped up the time it takes to snap pictures -- it's now almost instantaneous. Otherwise, you have options for a 5x digital zoom (which produces results that look like a digital zoom) and basic on / off / auto settings for the flash. It's pretty bare bones, and we wouldn't have minded a few basic options like white balance settings -- but c'mon, this is Apple we're talking about. Luckily, the App Store is chock full of applications that improve upon the stock camera app, we already have handful of new ones that take advantage of the new sensor.

As far as video goes, we were definitely impressed by the 720p capture, though there are stability issues with the lens and the all-too-familiar "jellyvision" CMOS issues that tend to rear their head if you're not holding the phone very steady. Still, we can't see carrying around a Flip HD instead of just keeping this in our pocket (though as we said, we'd like to see a higher storage capacity). Everything we shot looked crisp and mostly artifact-free, and we didn't see any hiccups in the 30 FPS rate Apple claims, even in lower light. Adding iMovie to the mix for on-the-fly editing is a nice touch too (more on that in the software section). The video below was shot and edited completely in-phone, so enjoy.

Around front, the VGA camera is... well, a VGA camera. It actually does a fine job of capturing your face during video calls, and worked surprisingly well in low light, but it's not going to win any prizes for being the most advanced shooter on a handset. It does provide for some interesting angle options when it comes to video shooting, and we expect a lot of people will be taking advantage of the weirdly video game-like perspective. All in all, it looks good, but it's pretty utilitarian.

Software

With its easy-to-use interface, amazing features, and rock-solid stability, iOS — Apple’s mobile operating system — is the foundation of iPhone. And even as other phones try to catch up, the technologies and features built into iOS 4 keep it years ahead of the competition.

As with the other revisions to Apple's phone line, the hardware is only half of the story. Along with the iPhone 4 comes iOS 4, the re-branded iPhone OS which boasts loads of new features, most notably a very Apple-ized version of smartphone multitasking, a video calling feature dubbed FaceTime, folders so you can organize your apps, enhanced Mail, and lots of other nips and tucks -- both big and small -- that refine the company's growing operating system. Additionally, Apple has ported the iPad's iBooks to the smaller screen, and has created a new version of its popular iMovie just for the iPhone 4. Overall, the OS is still very much the same as it's always been, but there are some big changes here that bear investigation.

Game Center

iOS 4 introduces the Game Center app. An out-of-the-box social gaming network for iPhone 4 and iPod touch.1 Invite friends to join. Then totally crush them. Take a look at how your score ranks among your friends and other players of each game. Compare game achievements with your friends. Get matched up and put together a select group of friends to play. Or choose to automatically go up against people you don’t know in a multiplayer game.

Multitasking

This is a big one, and more than just a little controversial. Since the dawn of apps for the iPhone (remember, way back in 2008?), people have been up in arms about the lack of third-party backgrounding for applications. Sure, you could keep Mail, Safari, iPod, and a few other Apple programs cranking while you used your phone, but those privileges were strictly off limits for third-party devs working on the device. It's arguable that one of the driving forces behind the jailbreaking movement was a desire for this feature -- something a phone as powerful as the iPhone was clearly capable of. Apple's argument has always been that multitasking causes an undue amount of battery drain from phones, and had to be approached with caution, lest we all end up with juiceless phones at high noon. Recently, however, that tune has changed. Apple has -- in true Apple fashion -- "figured out" how to "do multitasking right" -- namely, the company isn't allowing full backgrounding as much as it's allowing a handful of APIs that mimic backgrounding. Things like holding onto a GPS signal, letting music play in the background, staying connected to VoIP calls (or receiving them), and fast switching (basically a way for you to return quickly to exactly where you left off in an app).

So, does Apple pull it off? Can this scarce handful of APIs makeup for true backgrounding? In a word: yep.

Here's the thing -- this may not be "true" multitasking for a lot of us, but it amounts to multitasking for most of us. That is, it looks, feels, and acts like multitasking, so it's pretty tough to complain about it. In fact: we're not going to complain about it, especially given the fact that some of our favorite apps -- the IRC client Colloquy being one of them -- do just about exactly what we need them to do, all according to Apple's rules and regulations. Previous to the new OS, we'd been jailbreaking our phone just to keep an IRC session running in the background. Now, utilizing some of those new APIs, the Colloquy developers have created an elegant and useful solution that pleases both users and the Cupertino Cops. The point is: it works, it does so bug free, and without a major drain on battery life (quite the contrary... more on that in a moment). We're not saying we liked waiting for this kind of thing to come around, and yes, we'd prefer something more open and flexible -- but this works, and works well.

So how is Apple making this magic happen? Here's a breakdown of just exactly what multitasking really means (and feels like) on the new iPhone (and the 3GS):
Fast app switching: You know how you can leave off in Mail halfway through writing a response and go back to exactly where you were? Well that happens everywhere now. When you leave the app, you go back in exactly the same place. And it happens quickly. Fast app switching is essentially like toggling between "paused" applications. This combined with Apple's new app switcher (double tap the home button to bring up your most recently used apps) destroys that annoying iPhone feeling of going in and out and in and out. It just doesn't exist anymore, provided all your apps are up to date, which is going to take some time. It's amazing how much this single feature counts -- it's definitely one of the prime movers here, and it's so simple it's stupid. We would have liked to see options for "favorite" apps or some way to prioritize what you're switching to, but once you get used to this system -- which just puts whatever you've used most recently to the far left -- it makes some sense.
Task completion: Basically, task completion lets an app do its thing even if you leave it. So if you're uploading or downloading a picture in Evernote or Dropbox, or saving an article in the New York Times app, even if you navigate away, the job is done when you get back to the app. This accounts for a lot of what we think of as multitasking. Most of your apps are just idling -- it's only when you interact with them that it counts. We don't know the boundaries for this API, though it seems to leave a lot of room for creative use. We know it's not just big jobs, it's little ones too -- Colloquy uses this feature to keep you connected to your IRC host. To be honest, that kind of behavior is one thing we thought we wouldn't see in iOS 4, and here it is. Hopefully Twitter app devs and other instant messaging clients will utilize the API in a similar manner.
Background audio and VoIP: These two are straight forward. The first allows for music playing apps to keep their stream running in the background (and even gives them little widget controls in the app switcher), and the second allows VoIP connections to stay active. That means you can stay on a Skype call and go check your mail, but it also means that the VoIP connection will be aware of incoming calls when you're not actively using an app. Additionally, this API can be used to allow for recording even if you exit an app, as demonstrated effectively in the new version of Evernote.
Background GPS: Basically, GPS apps can keep running in the background... for obvious reasons. This one will drain your battery if you're not docked -- but who's using a GPS app and not plugging that thing in? Okay, we might be a little guilty of that. Regardless, this will keep your navigation software afloat if you have to take a call, and apparently will let GPS-centric apps like FourSquare check in even if you're not running it in the foreground.
Apple combines these heavy hitters with more familiar tricks, like push notifications, to excellent effect. We know that the hardcore users will cry foul because a lot of this doesn't amount to "true" multitasking, but we also know that often solutions to problems come in different colors. Apple found a way in iOS-4 to solve a pretty good amount of its major problems in this department, and so far what we've seen is very promising. If it's only going to get better from here, we don't mind coming along for the ride. But it better only get better, Apple.


Video Chat & Face Time

It’s amazing to see one of my most wanted apps coming to life with i-Phone4, It is cool how video acceleration works smooth over all your Video Chat apps (Yahoo, V-Talk (Google), Skype). Other than these Phone to PC or Phone apps , there is a dedicated i-Phone to i-Phone video chat apps that brings video calling so called Face Time Calling to life.

We're certainly impressed by the concept and Apple's willingness to open up their "FaceTime standard" to anyone who wants to get in on the party. That means that developers on any platform -- provided they can meet all the necessary requirements -- can create applications that talk via the protocol (or set of protocols, really). We're also impressed with the tech itself, which feels polished and slick out of the gate.

We're also impressed with the tech itself, which feels polished and slick out of the gate. But right now, there's only one way to do FaceTime calls, and that's via the iPhone 4... and only over WiFi, which means that the opportunity to make these calls is pretty limited for now. Additionally, in our testing, we found that you really need to have a good, strong, nearby WiFi signal to hang onto a connection. More than once we had video freeze on us, and we had one fully dropped call because someone went out of the WiFi range, but hey... you need to be in range for even the most basic tasks, so we can't fault Apple too much for that. It does seem clear that the iPhone video chats are moving quite a few bits around, however. What's nice about FaceTime is that unlike Qik or other third-party options for something like the EVO, there's no setup here and it's completely integrated into the dialer of the phone -- meaning the only hangup is whether or not you have decent WiFi.

But what is it like? Well in truth, it's actually a teensy bit amazing. Yes, we're a little numb to the PR speak about how game changing it is, but there's still something deeply sci-fi about dialing up a friend and being able to hold this thing in your hand and have a video chat. We did a call with Apple's Greg Joswiak while he was in Paris (see the image above), and when he walked outside and flipped the camera to show us the Eiffel Tower, it was a legitimately weird experience -- a "you are there" moment. As you can see in the call below with USA Today's Ed Baig (his take on the iPhone 4 is right here), it's a pretty new way to talk to someone, at least for us. Having a random face-to-face conversation with a kid about what he's having for lunch is just the tip of the iceberg -- we can definitely see this feature coming into play in all sorts of ways in our lives.

Now a days I sprangly use my laptops for video chat, Skype & Yahoo video calling apps excels with the i-Phone4, the most intresting feature was my wife who always complains about my network speed as most of the time my video chats get dropped in between started complementing my video chat through user experiance from the other end of the world. Having a random face-to-face conversation with a kid about what he's having for lunch is just the tip of the iceberg -- we can definitely see this feature coming into play in all sorts of ways in our lives and it is.

Battery Life

Battery Life is decent, i-Phone 4 has got a built-in rechargeable lithium-ion battery (as Apples useless trade mark you cannnot remove the battery).
It Charges via USB to computer system or power adapter or any USB power source with Apples teademark cable.

Apple claims of

1.Talk time: Up to 7 hours on 3GUp to 14 hours on 2G (GSM model only)
2.Standby time: Up to 300 hours
3.Internet use: Up to 6 hours on 3GUp to 10 hours on Wi-Fi
4.Video playback: Up to 10 hours
5.Audio playback: Up to 40 hours

But when I put the phone to practical use with most of my apps enabled and active in the baground except GPS, I can claim

1.Talk time: Up to 4-5 hours on 3G Up to 10 hours on 2G (GSM model only)
2.Standby time: Up to 200 hours
3.Internet use: Up to 4 hours on 3G Up to 6 hours on Wi-Fi on full charge
4.Video playback: Up to 6 hours
5.Audio playback: Up to 38 hours

Over all battery performance is decent , but be care full when your 3G+WiFi+GPS are enabled, When you multitask with lots of apps always keep an eye on the battery life. The will die with unexpected operational time. It's better to switch off your 3G when not required.


Thanks to external battery backup pouch that I have with i-Phone4 it gives me an other 90-100% charge without plugging the phone to any USB cables, If you are a serious internet user its advisable to have this external battery power back up.

Internet Tethering

Its an other cool function that I loved to have in my i-Phone. For most of the NRI's they need to have the VOIP SIP Phones clents in their mobile phones which requires internet, back at home your laptop needs internet for Video chat or Voice chat, So we were forced to have two net connections independant for Phone and other wireless router or DSL LAN for the laptops which some times really puts a dent on my wallet.

People have already thought about having one internet connection on their phone that could be shared across any media device when required, this feature of Internet Tethering was there in the market long time back with other smart phones but for i-Phones you need to jail break to use this app. But now with iOS4 this is simply possible to use your i-Phone as a modem

1.Go to the Settings screen.
2. Next select General.
3. Select Network options.
4. Now select Internet Tethering to enable the device to act as a modem.
5. Finally use your finger and slide the Internet Tethering to On.

Mail Improvements

For a lot of us, the new tweaks to the iPhone's Mail app have seriously been a long time coming. Among the major improvements in iOS 4 are a unified inbox and threaded messaging (finally!) -- both of which have made dealing with email on the iPhone a considerably more enjoyable experience.

I still think that the mail client is lacking in comparison to Gmail, but that has more to do with our addiction to Gmail than anything else, we suspect. Overall, Mail feels much more complete now, and Apple has solved the same problem in Mail that it had with app switching -- that feeling of constantly jumping into and out of your inboxes.

Now I use my Companys, Clients, Googls, Yahoos and AIM mail configured with my i-Phone, it works really smooth. You will have to use it to feel it.

Remarks

These remarks are my personnal remarks after using this Phone for more than 6-Months, I have used Simbian, Android and Windows OS phones for quite some time and settles with a i-Phone for its sturdy operational design.

1. iPhone 4 is the best Smartphone on the market right now, it doesn’t mean the close competitor Android is out of the market but they have a long way to go till they catch up with phone head to head. (I Predict at least for a year from now till end of 2012, iPhone will rule the smart phone market)

2. The combination of gorgeous new hardware, that amazing display, upgraded cameras, and major improvements to the operating system make this an extremely formidable package.


3. Yes, there are still pain points that I want to see Apple fix, and yes, there are some amazing alternatives to the iPhone 4 out there. But when it comes to the total package -- fit and finish in both software and hardware, performance, app selection, and all of the little details that make a device like this what it is -- we think it's the cream of the current crop market.

4. I won't argue that a lot of this is a matter of taste -- some people will just prefer the way Android or Symbian works to the iPhone, and others will be on the lookout for a hardware keyboard or a particular asset that the iPhone 4 lacks -- but in terms of the total picture, it's tough to deny that Apple has moved one step past the competition with this phone.

5. For the smart phone beginners or core users you can just go for i-Phone 4 with nil hesitation.

6. Do you have a question “ Is it worthy for the extra money that I have to shell out to buy a officially un-locked i-Phone ? why not their competitors?, So far it’s a fact that i-Phone competitors are still competitors who has not won the competition .

7. If you want to buy a straight forward winner, for sure with no doubt it’s i-Phone at least for the time being, no one can guess how long they can keep that edge.

For any doubts or clarification regarding iPhone-4 feel free to mail me (regan.gpr@gmail.com)

Thanks & Regards,
