Comparison of 2 Hottest phones – Apple iPhone 4 & HTC EVO 4G

In my last article I compared iPhone 3GS and Apple iPhone 4. iPhone 4 is far better than Apple 3GS. Now in this article I m comparing Apple iPhone 4 with latest high demanding Android phone HTC EVO 4G. Both of these phones are best at their level. Apple’s latest iPhone 4 is in direct competition with HTC EVO 4G. Let’s compare both phones.

Display & Design- The iPhone 4 has a 3.5-inch screen and the pixel resolution 960×640 pixels which is really best. iPhone 4 edges are a little sharper and it’s not as pleasant to hold. HTC EVO’s 4.3-inch screen is amazing. Screen size is perfect for watching videos and browsing the web. But EVO can not compete with the iPhone 4 on the resolution and only has a pixel resolution of 480×800 pixels – which is not as good as the iPhone 4’s 960×640 pixel resolution.

The new touchpad with multitouch and IPS technology is called Retina Display (326 pixels per inch). Due to the high resolution the displayed text, video and images are clear The iPhone is made of glass and metal The HTC EVO is mostly plastic. The iPhone is thinner (9.3mm vs. 12.7mm) than HTC. Both Phones are comfortable to use and fit fine in a pocket.

Processors-EVO 4G has 1GHz processor that makes everything snappy and stable. Multitasking was already easier since 1GHz processor became a need of Smartphones. HD videos (up to 720p) don’t lag or stutter, we can work on multiple applications without hanging our device, we can play games while something is being downloaded over Wi-Fi or 3G, etc.

The iPhone 4 uses the same capable A4 processor as the iPad, and the EVO 4 uses the hotrod Qualcomm Snapdragon running at an impressive 1GHz. You’ll have to wait for the iPhone 4 release to see head-to-head benchmarks, but AnandTech pitted the iPad against the EVO 4G and found a 37.6 percent real-life performance gain in page load times. Of course, different operating systems and a range of other variables make this far from scientific, and Apple could underclock the model in the iPhone 4 for battery life, further throwing a wrench into the works. Bottom line: Until the iPhone 4 makes it to the wild, it’s too early to tell how it will perform beside the EVO 4G.

Camera-Apple iPhone 4 has new fangle 5 megapixel camera shoots in 2592×1944 pixels, has autofocus and also LED flash and 5 x digital zoom and the front-facing cam, which shoots 1.3 megapixels to Apple’s VGA (0.3 megapixel) cam so, a lot better than the iPhone 3GS then. But It can be 8-megapixel cameras which is very common in these days.

“Steve Jobs claimed that in his iPhone 4 keynote that Apple wanted to create better pictures rather than just increasing megapixels. And to do this, Apple has kept the pixel sensors the same, but increased the number of pixels available in the final photo – meaning, you get a better-looking snap.”

HTC has packed a massive 8 megapixel camera with Auto Focus and 2x LED Flash in the HTC EVO, which, obviously, takes Apple to the cleaners in the megapixel front. Images are extremely brilliant in day light and satisfactory under low-light conditions. Dual LED flash has now become a common treat for Smartphones. However, we cannot count on this dual-LED flash of EVO 4G because it flashes too much and reduces the natural feel of the picture in low-light conditions. It’s something that’s utterly missing in every camera phone nowadays. For video, both cameras are capable of high-def 720p recording, but the iPhone 4 can shoot at a full 30 frames per second while the EVO 4G can only do 25. I think both phones are equally good. Apple has more focus on Picture quality and HTC gave preference to MegaPixels.

Battery-iPhone 4 works up to 7 hours in 3G networks and 8 hours in 2G networks, as for HTC EVO 4G the talking time is up to 6 hours. It’s just a matter of 1 hour but still Apple wins here.

Operating System- Apple’s iOS undoubtedly lacks the flexible open ecosystem of Android, which allows software like game console emulators that Apple has banned, but Apple holds the upper hand in selection, boasting 225,000 third-party apps to Android’s 70,000 or so, at last count. The latest release also alleviates some of the most frequent complaints about previous versions, like the lack of multitasking and folders for apps.

Some Other features on both devices:

-    Both Apple and HTC are promising HD video recording from their devices.
-    iPhone has Facetime video calling over Wi-Fi, Retina Display that provides brilliant display on 960 by 640 resolution.
-    HTC EVO 4G has HDMIout, wide display of 4.3”, Wimaxin a phone (make your phone a Wi-Fi hotspot), nice 8MP camera phone in day-light.
-    The iPhone 4 offers the same maximum storage as the EVO 4G, and for less money
-    These both are touchscreen phones. But the iPhone still offers the best touchscreen keyboard we’ve ever used in actual practice, and the addition of spellcheck in iOS 4 only helps cement that.

So In my point of view as comparing the devices from HTC and Apple it’s very difficult to decide which smart phone is better. But I can say Apple’s iPhone 4 appears to be a better deal. iPhone 4 is substantially smaller, has a higher resolution screen, and offers more storage for the money, good picture quality, better Video calling, better multimedia and Web-browsing and many more feature which puts iphone 4 upper hand. But Keep in Mind that Apple iphone 4 wins with little margin only.

Comparison of Apple iPhone 3GS with iPhone 4

Few Days ago only Apple iPhone 4 is launched and now it is in market available for purchase. Apple 4 is the thinnest smartphone offering from Apple, and has included a bunch of most advanced features and hardware specifications. On the first day only Apple may have sold more than 1.5 million iPhone 4s. While Apple sold 1 million iPhone 3G units in the first weekend it went on sale in 2008. Apple 3Gs is also good but lacking somewhere compare to Apple 4. Here we are going to compare both of these highly demanded models.

Size and weight – iPhone 4 is 24 per cent thinner than its predecessor at 9.3mm instead of 12.3mm. It’s also ever so slightly wider by 3.5mm. In weight, iPhone 4 is slightly heavier at 137g instead of 135g.

Display Screen – The Screen size of the both phone are same. Both have 3.5-inch diagonal Screen. But in resolution it differs. The iPhone 3GS’s LCD display has a resolution of 320×480 pixels. iPhone 4′s LED backlit IPS LCD display has a 640×960 resolution at 326ppi and an 800:1 contrast ratio. iPhone 4′s Retina Display radiates over the iPhone 3GS. Looking closely to the iPhone 3Gs text and icons are a bit more jagged compare to iPhone 4.

Power and battery – New iPhone 4 is improved a lot in terms of battery life. Steve Jobs claims a 40 per cent improvement for the iPhone 4 over the 3GS. 3Gs has Up to 5 hours talk time / data on 3G, 12 hours on 2G talk time while iPhone 4 has Up to 7 hours talk time on 3G, 14 hours on 2G.

Storage Capacity – iPhone 4 is only available with 16 GB and 32 GB while iphone 3Gs is available in 8GB also.

Camera & Video Recording – iPhone 4 is very much improved in its camera feature. It is not as good as other best camera phones. But it is far better while compare to iPhone 3Gs. iPhone 4 has 5 megapixel of camera instead of 3 megapixel and the addition of an LED flash which can also be used for the video. iPhone 4 also adds a front-facing camera for FaceTime Wi-Fi video calls and more.

3GS supports video recording at VGA (30fps) and iPhone 4, as predicted, pokes a finger in the eye of devices like the Flip HD, with its own HD (720p, 30fps) recording.

Operating System – The iPhone 3GS currently runs version 3.1 OS. However iPhone 4 will be released operating on iOS 4. iOS 4 allows MultiTasking. You can run your favorite third-party apps and switch between them instantly without slowing down the performance of the foreground app or draining the battery unnecessarily. Organize apps into folders with drag-and-drop simplicity. See messages from all your accounts in a unified inbox.
