More powerful features: new iPhone 4G review

Apple CEO Steve Jobs opened the 2010 Worldwide Developers Conference on 8th, June by announcing the latest iPhone incarnation, the iPhone 4G. It will be available exclusively with AT&T starting June 24, with 5 countries at launch (US, France, Germany, UK, Japan), with 18 more following in July. The price with service is fair--US$199 for the 16GB phone or US$299 for the 32GB device--and both models come in white and black versions. Then let's have a close look at the new iPhone 4G: How does the new iPhone improved compare with the iPhone 3G S?

Display
The iPhone 4G features a 940 * 640-pixel (or 326 pixels per square inch) Apple calls it a "Retina Display", which is four times the resolution of previous iPhone models. It's rated at 326ppi, which Apple claims is beyond the human eye's limit of distinction. Check out an example of the new screen up against the iPhone 3G after the break. Similar to the iPad, it's an IPS display, offering 800:1 contrast. The thickness of it is only 9.3 millimeters, 24% thinner than iPhone 3GS. Apple Company says, iPhone 4G is the thinnest smartphone in the world.
New features of iPhone 4G
Firstly, iPhone 4G comes with iOS 4, the newest version of the world's most advanced mobile operating system. With over 100 new features, it includes Multitasking, Folders, enhanced Mail, deeper Enterprise support and Apple's new iAd mobile advertising platform. With Multitasking, users can now instantly switch between any of their apps while preserving battery life. With Folders, users can easily organize their apps into collections by simply dragging one app on top of another. A folder is automatically created and named based on the category of apps selected. Users can change the name of any folder at any time. In addition, users can now customize their lock and home screens with an array of supplied wallpapers or with any of the photos on their phone.
Secondly, the iPhone 4G will feature the same A4 chip that's found in the iPad. The result is a faster processor plus improved battery life (its supports seven hours of talk time on 3G networks, up to 10 hours of web browsing on Wi-Fi and up to six hours on 3G, and up to 10 hours of video playback and up to 40 hours of audio playback). Thirdly, the iPhone 3GS gave us a compass, but the iPhone 4G raises the bar by offering a three-axis gyroscope. Like on an airplane, you'll get pitch, roll, and yaw, and it's tied with the accelerometer to provide six-axis motion sensing. Though by all means it will be useful to app developers, it also just looks like a lot of fun.
Moreover, the iPhone 4G's front-facing camera is a 640-by-480-pixel camera (three-tenths of a megapixel, if you're curious) designed to be used primarily with the new FaceTime video-chat system, though it will also work well as a way to take self-portraits. With the FaceTime, you can see your loved ones and friends anywhere there is Wi-Fi. Using FaceTime is as easy as making a regular voice call, with no set-up required, and you can instantly switch to the rear camera to show others what you are seeing with just a tap.
Camera Changes and Powerful Multimedia functions
iPhone 4G features a new 5 megapixel autofocus camera with a 5x dig ital zoom, a backside illuminated sensor and built-in LED flash that allows you to take amazing pictures even in low light and dark environments. iPhone 4G lets you record and edit incredible HD video and the popular tap to focus feature now works while recording video. You can use the iPhone 4Gs LED flash for both still photography and video recording. The demo looks great, even if the iPhone isn't the first cell phone to offer this capability. The new iMovie? app for iPhone lets you combine movie clips, add dynamic transitions and themes and include photos and music, and users can buy it for just $4.99 through the App Store right on their phone.
With its' build-in powerful multimedia player, iPhone 4G supports lots of audio and video formats. Such as: audio formats: AAC (8 to 320 kbps), Protected AAC (from iTunes Store), HE-AAC, MP3 (8 to 320 kbps), MP3 VBR, Audible (2, 3 and 4), Apple Lossless, AIFF and WAV. and video formats: H.264, up to 720 high-definition at a c onstant frames per second, Main profile up to level 3.1 with AAC-LC audio up to 160 kbps, 48khz, stereo audio in .M4V, .MP4, and .MOV file formats; MPEG-4 video up to 2.5 mbps, 640 by 480 pixels, 30 frames per second, Simple profile with AAC-LC audio format up to 160 kbps, 48khz, stereo audio in .M4V, .MP4, and .MOV file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, with ulaw audio format and PCM stereo audio in. AVI file format.
But, it is a small shortcoming that iPhone 4G could not play DVDs. If you want to play DVD with it, you may use Nidesoft DVD Ripper which helps you convert DVD to all popular video or audio formats easily to convert DVD files into iPhone 4G compatible formats or you have some video or audio files which iPhone 4G could not support in some case, you may select Nidesoft Video Converter to convert all other video files into iPhone 4G. It is powerful video conversion software which could convert video and au dio files between all popular formats. With these two assistant software, you may enjoy your DVD or any video and audio files in iPhone 4G at anytime and anywhere.
Conclusion
Through the above description, we know iPhone 4G have improved much more functions than iPhone 3GS, such as FaceTime, Processor, Camera, Gyroscope and application system and so on. And, "iPhone 4G is the biggest leap since the original iPhone," said Steve Jobs, Apple's CEO. So, iPhone 4G is filled with the hope of us. Of course, nobody knows the result before it is published; let's just wait for its official release date of June 24th.

How's your Android smartphone battery life?

Do you own an Android-powered smartphone ortablet? If so, how's your battery life?

I ask because based on what I've heard from others and experienced myself, it's atrocious. And I'm wondering if it's symptomatic of the Android platform as a whole, or just the nature of modern-day mobile gear. Cast your vote in our poll, then meet me below for more discussion.

As I noted in a recent BNET post,"The dirty Android secret no one's talking about," I first encountered battery issues with the Virgin Mobile Samsung Intercept. Out of the box, it couldn't last 24 hourseven with e-mail sync and other battery-consuming tasks disabled.

Rather, I'd start the day with it fully charged, and by late afternoon it would be dead. Thankfully,freeware app JuiceDefender made a huge difference, allowing me to go a full two days without AC assistance.

Then I updated the OS from 2.1 to 2.2 (Froyo), which I'd heard was much better at power managementand battery life actually got worse. Now, once again, I'm lucky Dell vostro 1510 battery,Dell xps m1330 laptop battery to get 24 hours.

Last week I had the opportunity toreview Samsung's Galaxy Tab Wi-Fi, which I found to be excellent overalluntil the next morning, when I woke up towait for ita dead tablet. The aforementioned JuiceDefender helps a little, but ultimately the Tab is seriously hobbled by its battery. And I am seriously disappointed.

Or perhaps I'm just spoiled. See, myiPad is the Energizer Bunny of tablets. I can easily go a week without charging it, including a few days when I don't even pick it up. It doesn't just sit there consuming power when it's off, which obviously the Galaxy Tab does.

Likewise, myiPhone 4 seems to sip juice, not guzzle it. I may see low-battery warnings after two days off the charger, but I very rarely pick it up and find it to be dead.

So those are my experiences. Now let's hear yours. Does your Android phone or tablet have disappointing battery life? Or are you just accustomed to plugging it in at night, no big deal? Heck, maybe your device hums along for days without needing a recharge Dell latitude d820 battery,Dell gd761 battery. Whatever the case, tell me about it in the comments!

Laptop batteries are crucial when working on the road. To get maximum performance from yourlaptop battery, fully optimize the laptop's power management features prior to use. However, there is a trade off when setting your laptop power management. You will achieve better power conservation in exchange for lesser computing performance. The power management system conserves thelaptop batteries power by setting the processor to run at a slower speed, dimming the laptop screen, slowing down the hard drive when it's not in use and causing the machine to go into sleep or suspend mode when it is inactive. Your laptop user's guide will provide information relating to specific power management features.

KA08 Mini iPhone Clone Review: A Look At The Features And Performance On This Tiny Knock Off

The new mini KA08 iPhone replicas are becoming all the rage. People really enjoy getting all of the features in a smaller package with a much smaller monthly cost. In the following article, I'll give a general overview of the phone and highlight some of the features that have made this tiny clone so popular.

Sleeker, Smaller, More Colorful: This little mini is the size of a credit card and not much wider. I believe that there is a pretty large subset of consumers who love Apple's technology but who find the actual iPhone a little bulky and cumbersome. This phone really appeals to these folks because this gadget can slide into a small pocket or a thin slot in your purse. It doesn't weigh much or drag you down.

It's also available in new colors that you can't get from apple unless you go with a skin or are able to find a face plate. But, the KA08's colors come from the actual housing of the phone. You're not stuck with black, white, or even red (although you can get these colors if you want them.) There is also pastel pink, hot pink, different shades of blues, greens, and yellows, etc.

Everything In One KA08 Phone: The small size of this one doesn't mean that the manufacturer has skimped on what you are getting. This phone is still a dual sim. It is quad band. It has the shake and tilt feature and an upgraded 2.0 MP camera, and Bluetooth. It has a radio, ebook reader, MP3 / MP4 player and video recorder. It can hold up to 8GB. There is web browsing, email, sms, mms, and ems. It has a long battery life, holds 300 groups of contracts, and has calendar, notes, to do list, etc.

It still has the touch screen that pops up with a digital QWERTY keyboard. It takes a bit of getting used to since this is a smaller phone, but a stylus can make pretty quick work of this. Many people consider this a fair trade off for such a light, compact phone.

Low Cost: Another big draw of these small replicas is the smaller price. These are rarely over $100 (and are usually closer to $50) and because they take all activated GSM sim cards, including pre paid and pay as you go, you can be free of the monthly contract if you chose to be. And, you can often get low cost pre paid Internet cards that allow you to free yourself from a monthly data package. Over the life of the phone, this can really add up. Many consumers today don't want to have to pay for service that they don't actually use. And, they don't want to be stuck with a monthly bill ifthey should have a change in circumstances.

iPhone 4 Review - 7 Key New Improvements Made

Looking for some more information about the new iPhone 4? First up, the all new design and style. The iPhone 4 marks the very first revolutionary alteration ever since the iPhone first launched in 2007. Glass on the front and back and steel around the sides promises to give the iPhone 4 a truly unique look and feel. At 9.3mm thick, the iPhone 4 is also incredibly thin, 24% thinner than the iPhone 3GS.. Some other design and style alterations reveal a main camera with an LED flash (thank goodness for that!), a front facing camera, trendy volume settings and, in what Jobs states is a world first, an antenna that is part of the key structural element of the iPhone 4.

The next area we will look at is a feature that Apple are labelling Retina Display that is the brand new display screen technology used by the iPhone 4. A new 3.5-inch "Retina" IPS LCD display is going to be the norm for all future iPhone versions (including the iPhone 4) and can offer 326 pixels per inch with an overall resolution of 960 by 640. Exactly what does this implies? Well it has a higher resolution than any other mobile phone currently available on the market and is going to provide much sharper photographs and zoom feature.
Third, the iPhone 4 s going to be powered by A4 chip which is the same one used on the iPad is what will take your breath away. Among all the things it will do which are awesome, the thing you will really notice is that the power management feature it has is going to extend the battery life which has already been beefed up independently. Having 7 hours of call time is going to be nice without any doubt. The gyroscope is going to take gaming to a whole new level, but if you aren't a gamer that won't matter.

Next in the list is something Apple are very pleased with; the iPhone 4 has a built in gyroscope. This 3 axis gyro works in conjunction with the accelerometer and compass resulting in six axis which is ideal for gaming. Think the Wii and you're going to get close. Jobs showed off this new feature by playing a game, which looked a bit like Jenga.

Apple's latest features are coming thick and fast and number five is a big one. The primary digital ca mera is the subject of a "whole new camera system" and it will be upgraded from three to five mps, the camera also features a backside illuminated sensor which increases the quality of images shot in low-light. It's also a lot better for video footage, given that it's carrying an HD-camera that will be able to shoot 720p at 30fps what Apple is labelling real High definition

Feature six is one we are already acquainted with, the new iPhone OS 4. We are not going to go into too much depth right here, as this is a review of the mobile phone and not the software, nevertheless the high light of the newest version of iPhone OS will be a chance to run multiple programs simultaneously (multi-task). Plus whilst Apple themselves will happily tell you they weren't the first to offer a multi-tasking smartphone, they are comfortable they managed to construct something that will not obliterate your battery. We'll reserve judgement until we've had a go on the new iPhone Operat ing System.

Seven is another function we are already familiar with but one that's exciting in any case; iBooks will be featured on the all new iPhone 4.

Ultimately, number eight is iAds. A tool designed to help developers earn money so that in turn they can drive down the cost of apps and offer a wider selection of free and low cost apps. iAds is kind of self explanatory; it automatically inserts advertising space into an app (providing the creator selects this option) and earns the developer added revenue from clicks and downloads. An odd feature to finish on from a customer point of view but one that is sure to have app developers drooling.

That's it, are look at the new iPhone 4 and just a tiny review of some of the 100 extra features we'll be enjoying in the coming months.
