When it comes to smarphones, some buyers can be carried away by big noticeable features like processor, camera and screen display. However, overlooking simple features can make a big difference when you buy a handset. Nobody knows it better than those who bought Nexus 5 original version. Sadly, Google's upcoming LG Nexus 5X aka Nexus 5 (2015) may disappoint the fans due to two simple but important features.

The Nexus 5, which was released in 2013, was a big success. It was discontinued without a single price cut despite consistent demand after the release of Motorola Nexus 6. Everything about it was good at that time (it is still good) except for two features – memory and battery.

The device came with 8 GB and 16 GB internal memory, which many found inadequate. It would have been fine if it came with a microSD card slot. But there was no such facility.

Though Nexus 5X is expected to come with 16/32 GB internal storage, some may still want more. Nexus fans will be disappointed with the device for not offering expandable storage facility.

Nexus 5 was almost pathetic when it came to battery. It has a big screen with high screen resolution besides powerful hardware. So, it consumes a lot of battery. However, since it houses only a 2,300 mAh battery, the power gets exhausted after a few hours. The small battery is non-removable, leaving users with no option but to buy a new device if battery wears out.

It is reported that Nexus 5X will house a non-removable 2,700 mAh battery. The Android 6.0 Marshmallow OS is expected to improve battery life of devices running on it by double-fold but there are many who prefer a 3,000mAh battery or more.

The device is expected to be unveiled on 29 September along with Huawei Nexus 6 (2015) and will be released a few days later.

According to reports, Nexus 5X will sport a 5.2-inch screen with 1080 x 1920 pixels, powered by a Qualcomm Snapdragon 800 processor running Android 6.0 Marshmallow, packed with 3 GB RAM and house a 13 MP main camera and 2 MP front snapper.
