LG Optimus 4X HD: A Quad-Core Android Phone Review



THE LG OPTIMUS 4X HD ($560 unlocked) is LG’s first quad-core model. Powered by an Nvidia Tegra 3 processor, it also has a 4.7-inch display with a 1280-by-720-pixel resolu­tion. The Optimus 4X HD is available in Europe, but so far LG hasn't announced any plans for North America.
Superthin at 0.35 inch thick, the 4X HD has what LG calls a “True HD IPS display. Blacks look deep, colors are vivid, and whites seem bright. The screen suf­fers from oversaturation, though. Details usually were quite sharp in photos, but text rendering wasn't perfect.

LG Optimus 4X HD

Nvidia's Tegra 3 processor actually has a smaller fifth core to help phones con­serve battery life, handling Less-demanding tasks such as active standby.
On some benchmarks, the 4X HD outperformed rivals like the Samsung Galaxy S III. And its quad-core pow­er becomes abundantly clear in gaming: Graphics-heavy games on the 4X HD played smoothly and looked terrific.
After two passes in our tests, the Optimus 4X had an average battery life of 6 hours, 28 minutes. It runs the An­droid Ice Cream Sandwich operating system with an LG- branded user interface.
It also comes with built-in NFC (near-field communica­tions) for mobile payments.
Overall, the LG Optimus 4X HD has what it takes to com­pete with other top-of-the-line Android phones, and I hope that LG brings a version to the United States.

Motorola Atrix HD: An Excellent Deal



Motorola Atrix HD
THE MOTOROLA ATRIX HD ($100 with a two-year AT&T contract) is the first Android phone Motorola has released as a Google subsidiary.
It measures 5.26 inches tall by 2.75 inches wide; at only 0.43 inch thick, it fits easiLy into a pocket or hand­bag. It comes in either black or white. Instead of physical buttons, you get three “virtu­al” buttons, for Back, Home, and Recent Apps.
The phone’s name comes from its screen, a 4.5-inch, 720-by-1280-pixel “HD” dis­play. In sharpness and clarity of detail, the Atrix HD held its own against the GaLaxy S III and the iPhone 4S. Text was easy to read.
This Motorola phone runs on Android 4.0 (Ice Cream Sandwich), with a Motorola- made overlay.
It’s the first Motorola phone on AT&T to ship with SmartActions, an app that can help you conserve bat­tery life through reminders you set. Battery life wasn't the best: I had to recharge it after about 5 hours of mod­erate to heavy use.
A 1.5GHz dual-core Qual­comm Snapdragon proces­sor powers the Atrix HD; other phones with this pro­cessor have achieved high scores in our benchmarks.
Call quality in San Francis­co over AT&T's network was very good, as were the 4G LTE data speeds. Camera quality was disappointing.
The Atrix HD is mostly an excellent deal. It shows that these days, budget’’ doesn’t have to be synonymous with “inferior.” 

INTEL ATOM Z2460 FOR SMARTPHONES


 
INTEL ATOM Z2460 FOR SMARTPHONES
Intel’s new smartphone chip, which promises longer
battery life and even more powerful handsets

YOU may know the Intel Atom processor - it has been used in numerous netbooks before now. But now Intel has introduced a new version specifically designed for smartphones and tablet. And, at CES 2012, the chip giant also announced the Lenovo K800 would be the first smartphone featuring the new processor. But it's the tech behind this new handset which is of real interest and could really compete with ARM-based chips over the next few years.

ARM-based chips are used in pretty much all smartphones and tablets from the Apple iPhone and iPad, new Nokia Lumia 800, Asus and Samsung tablets and many more - even though these contain processors with names such as the Apple AS, Nvidia Tegra and Qualcomm Snapdragon, they are all based on the ARM design. Intel wants to compete with this and gain a slice of what has become a very lucrative market.

In addition to the announcement about Lenovo, Motorola will be next to launch handsets based on Intel Atom. The handsets will feature the Atom processor Z2460 platform, formerly known as Medfield. The chip is a single-core and, while this pales in comparison, to rivals such as the quad-core Nvidia Tegra 3, Intel hopes that by opting for a more efficient 32nm it can deliver better power efficiencies. Whether this works in practice naturally remains to be seen.

HTC Sensation XE Review and Ratings



HTC Sensation XE
Are-tooled Sensation complete with Beats Audio power
It might seem odd that HTC has re-booted the Sensation so soon after its launch, but since purchasing a significant stake in the Dr Dre-fronted Beats Audio, it’s decided to relaunch its top smartphone with some improved sonic clout.

Beats Audio may sound like nothing more than a Dr Dre-backed tag, but it does genuinely enhance sound, revving up your tired mP3 collection by offering richer bass and more defined vocal clarity using clever processing algorithms to clean up the sound.

The Sensation XE doesn’t look that different from the original model, with the same 4.3-inch Super LCD screen encased in an aluminium body. Subtle flashes of red and a new logo are the only clue to the enhanced auditory experience under the bonnet, and the bundled Beats earbuds in the box are the only difference from the original packaging. However, it’s beneath the hood that most of the improvements have occurred, and they certainly make a difference.

The first update is the CPU, with a dual core 1.5GHz option from Qualcomm providing more grunt that results in a smooth motion under the finger.

Sense has long been seen as one of the best Android overlays on the market, and with 3.0 the experience is even richer. The Sensation XE runs Sense 3.0, which brings spinning 3D animations, advanced widgets and simple power management from anywhere on the home screen.

Wired for sound
The qHD screen combined with Beats power provides a terrific media experience - both music and video perform extremely well on the 4.3-inch display. However, it’s the Beats Audio profile (activated when you plug in compatible headphones) that really makes the media shine: sound is dramatically increased in depth and clarity due to the in-built audio processing. On top of that, HTC has treated users to a decent 8MP camera and a movie download service called Watch that rivals the likes of Apple and Samsung for cost and breadth of content available.

The battery has been improved to a 1730mAh option to deal with the extra grunt the processor offers - but it’s still the power pack that provides one of the only negative elements of the Sensation XE. In a variety of usage scenarios - from minimal use on standby to heavy web browsing, media consuming and GPS tracking - the best amount of time between charges we managed was around 36 hours. If you keep the screen constantly turned on, you’ll sadly be looking at something like six hours of usage at best - not what we hoped for in a high-end smartphone.

That said, don’t let that battery put you off a cracking handset that will keep a smile on your face each time you discover a new feature.

If you’re someone that likes to listen to shedloads of music, watch video on the commute or browse web pages rendered with pin-sharp clarity, the HTC Sensation XE certainly won’t disappoint.

You will need to keep an eye on the battery meter at times to make sure you don’t end up cut adrift with no communication on a night out, but it’s a small hiccup on an otherwise decent smartphone.


HTC Radar | A dinky Windows phone for basic users



 HTC Radar
A dinky Windows phone for basic users

The HTC Radar is the latest smartphone to run Windows Phone 7-5, following on from the HTC Titan. With a smooth unibody design, HD video recording and 5MP camera, there’s a lot packed into a compact package.

Unibody - The term given to a device which is made out of a single piece of metal or plastic. Unibody design tends to offer a more solid feel

The Radar, which runs Windows Phone 7.5 (or ‘Mango’ to its friends; see page 62), is a solid little handset. It’s crafted from a single piece of metal and has enough weight (137g) to make it feel sturdy without giving your biceps a workout.

There’s no space for a microSD card (Windows Phone doesn’t allow for memory expansion) and there’s just 8GB storage - reduced to just 6.54GB once the operating system has taken its share; barely enough for some apps, music and photos.

The camera is only 5MP but still produced decent quality images. It’s suitable for those who only need occasional camera use.

Snap happy

As if to make up for the lack of megapixels, HTC spouts specs such as f/2.2 lens and BSI sensor. This may sound like marketing guff but they do help in the overall picture- taking process, and make the end results worthy of a print.
 
HTC’s form for decent cameras hasn’t been forgotten here. Firstly, having a camera button helps. You don’t have to fiddle around with gripping the phone a certain way or digging through menus that may be hard to see on a bright day. Wherever in the Windows Phone 7.5 Mango OS you may be, a long press on the camera button takes you to the camera screen.

The HTC Radar ships with a respectable 1520mAh battery. Remember this isn’t a dual core smartphone, so for a 1GHz processor and average-sized screen, this should see you through a day of
use comfortably. We took it off a charge at 7am and spent about 20 minutes fiddling with various settings and catching up on Twitter. Over the course of the next few hours, we sent more than 30 emails, a couple of texts and made a 21 minute phone call.

Mid-afternoon, we went running for 90 minutes with the RunKeeper app going, and listened to the FM radio for about half an hour in the early evening. The Radar kept going, and even by 10pm it still had about a third of its battery left. We didn’t use it much the following day and it managed to last until lunchtime before conking out.
If it’s a straight choice between the HTC Titan and the HTC Radar, we’d recommend the Radar every time, because it’s so much better in terms of value for money.

That said, it still feels like a work in progress. We know this will upset Windows fans, but we can’t help feeling that it’d be better to wait for the next crop of handsets or updates before committing.

After all, two years is a long time to be tied into a contract and Windows Phone is not a new platform any more, by any stretch of the imagination.
