Google has unveiled its much awaited LG Nexus 5X, which was earlier known by name Nexus 5 (2015), with several feature upgrades over its predecessor Nexus 5 (2013) but there are more reasons than one for users of the original version not to buy the new device.

LG Nexus 5X is expected to do good business but owners of the original Nexus 5 will be confused whether to opt for an upgrade or stick to their old device. Should Nexus 5 users buy the new Nexus 5X?

LG Nexus 5X is superior to its predecessor in almost every department. It also comes with a price tag starting at $379 (for 16 GB), which is just $20 more than the 16 GB version of Nexus 5 original version ($350).

Nexus 5X comes with features like 5.2-inch full HD screen with 1920x1080 resolution (423 ppi, pixel density), Qualcomm Snapdragon 808, Android 6.0 Marshmallow, 16GB/32GB internal storage, 2GB RAM, 12.3MP main camera, 5 MP front snapper and 2700 mAh battery.

On the other hand, Nexus 5 original version has a 4.95-inch True HD IPS+ screen with 1080 x 1920 pixels (445 ppi, pixel density), Qualcomm Snapdragon 800, Android 5.1.1 Lollipop (expected to get Android 6.0 Marshmallow soon), 16GB/32GB internal storage, 2GB RAM, 8 MP main camera, 1.3 MP front snapper and 2300mAh battery.

Looking at the specifications of both the devices, Nexus 5X is no doubt more powerful and it is expected to sell like hot cake. In the meantime, many users of Nexus 5 original version may still think the new device is not good enough.

Nexus 5 is a great device but there are two features that users are not happy with -- internal storage and short battery life. But did its predecessor solve these issues? The answer is "No".

Nexus 5X also has 16GB/32GB internal storage like its predecessor and sans microSD card slot. It comes with 2700 mAh battery, slightly bigger than the 2300mAh seen in its predecessor, but most Nexus fans might be looking for at least a 3000mAh battery. The new device has much better camera, processor, and bigger display but Nexus 5 has better screen resolution with 445 ppi (compared to 423 ppi).

So, there are chances of current Nexus 5 users to stick to their old devices instead of opting for an upgrade.
