Google and LG have decided offer a bigger display with the Nexus 5. It features a 4.95-inch full-HD (1080x1920 pixel) IPS+ LCD display which boasts a pixel density of 445ppi, and comes with Corning Gorilla Glass 3. On the other hand, the Nexus 4 sports a 4.7-inch HD (768x1280 pixels) IPS+ LCD display with a pixel density of 320ppi, and Corning Gorilla Glass 2. We've yet to get our hands on the Nexus 5, and for now, can't take a call on which display is better for now (in terms of viewing angles, colour accuracry, brightness and contrast), with both featuring the same display technology.
The Nexus 5 sports an 8-megapixel rear camera with OIS, a new addition to Nexus smartphone line-up. It also houses a 1.3-megapixel front-facing camera. On the camera front, the Nexus 4 was criticised for its relative average camera performance. However, Google has now acknowledged the issue and has introduced the optical image stabilisation (OIS) feature in the Nexus 5's camera, which should ensure sharper images and video. The rest of the imaging optics appears to be the same as the Nexus 4, with the same 8-megapixel sized rear camera, and 1.3-megapixel front camera. In addition, the camera app was also updated with Android 4.4 KitKat (which will make its way to the Nexus 4), with Photo Sphere for Panorama 360 degree shots; HDR+ mode for burst shots which automatically chooses the best shot.
The Nexus 5 is powered by top-of-the-line 2.3GHz Qualcomm Snapdragon 800 processor, which is coupled with the Adreno 330 GPU. Its predecessor, the Nexus 4, is powered by 1.5GHz quad-core Krait Snapdragon processor with Adreno 320 GPU.
It seems for the Nexus 5, Google and LG decided to stick with the flagship tradition and chose the Qualcomm's latest processor, available on nearly all the recently launched flagship smartphones like the Samsung Galaxy Note 3, LG G2 and Sony Xperia Z1.
There is an upgrade in the battery department as well; the Nexus 5 comes with 2300mAh battery which the manufacturer claims can deliver up to 17 hours of talktime (3G) and a standby time of up to 300 hours (3G). Nexus 4 came with a 2100mAh battery, which was rated to deliver up to 15 hours of talktime (3G), and 390 hours of standby time (3G).
Notably, the Nexus 5 does not feature expandable storage with a microSD card slot, once again knocking the smartphone off a potential purchase list for some users - the lack of microSD card support was perhaps the biggest omission the Nexus 4 was criticized for.
The Nexus 5 at 8.59mm is definitely slimmer than the Nexus 4, which is 9.1mm thick. It is also lighter at 130 grams, compared to the Nexus 4's 139 grams. The overall design has been also re-worked and instead of the glass back seen on Nexus 4, the Nexus 5 comes with a Nexus 7 (2013) tablet style-panel, featuring a matte finish and prominent Nexus branding.
Connectivity options on the Nexus 5 have also seen an upgrade with the much-requested addition of LTE network support. The Nexus 4 had been criticised heavily for not including support. The Nexus 5 brings dual-band Wi-Fi 802.11 ac as well. Not many other changes have been made on the Nexus 5 on the connectivity front.
The Nexus 5 also features Android Beam, an NFC enabled feature which lets users share digital details with just a tap of smartphone. Other connectivity features included are wireless charging support, and Bluetooth 4.0, which are also available on the Nexus 4. T
Google's new Nexus smartphone is the first device to run Android 4.4 KitKat out-of-the-box and is definitely an improved version of the Jelly Bean. The Nexus 4 will be receiving the update soon as well, and will have all the same features - so, only the preloaded aspect is different. The new features include a smart dialler, and Google-powered Caller ID. KitKat also brings the ability to wake the smartphone by just saying 'OK Google', a feature which was earlier seen on Moto X.
Google also claims that the Android 4.4 KitKat can now optimise memory and improve touchscreen response for better multitasking. Android 4.4 also bring some new features such as Hangouts app now can show messages and MMS; new immersive mode, offers full screen while reading, watching or playing, on swiping the edges offers navigation bar and status bar; native printing from Android, offers users an option to print documents, images and web pages from a device.
Nexus 5 is priced at $349 for the 16GB variant while the 32GB model costs at $399. In India, the Nexus 5 has been priced at Rs. 28,999 for the 16GB model while the 32GB variant is listed for Rs. 32,999.
On the other hand, the Nexus 4 16GB was launched at $349 in October 2012, and received a $100 price cut in August 2013. For the Indian pricing, the Nexus 4 16GB was launched at Rs. 25,999 in May.
Those considering upgrading from the Nexus 4 to the Nexus 5 will get a better-specced device that will deliver much faster performance, new Android 4.4 KitKat software out-of-the-box, improved camera, upgraded battery and LTE support (though not for India).
Once again, like the Nexus 4, the Nexus 5 is a great deal for those looking for a value for money performance Android smartphone - just the Snapdragon 800 chipset at this price is a steal.
The Nexus 5 has now been listed on the Indian Google Play store with a pricing of Rs. 28,999, while the Nexus 4 has been removed from the store completely, though we expect online retailers to continue listing it for a while, without a price drop.
