Display and Processor
The Nokia Lumia 630 comes with a 4.5 inch display with a resolution of 854×480 pixels which translates into a pixel density of 218 ppi and the Xolo Win Q900s has a relatively large screen measuring 4.7 inches with an increased resolution of 1280×720 pixels that gives it a pixel density of 312 ppi. The HD resolution on the Xolo phone will look good while the OGS panel will make the handset slim and the Dragon Trail Glass will keep the scratches away. On the other hand, the Lumia 630 features Corning Gorilla Glass 3 coating that is also responsible for preventing the scratches and damage. While the Lumia 630 features a 1.2 GHz quad core Snapdagon 400 under its hood, the Xolo Win Q900s is based on the Qualcomm reference model that features a 1.2 GHz Snapdragon 200 chipset. The latter is power efficient thereby capable of conserving the battery life. Apart from this, the Xolo phone excels with 1 GB of RAM as compared to the 512 MB of RAM in the Lumia 630, but it has to be noted that the Windows Phone platform can glide through swiftly irrespective of this difference in the RAM.
Camera and Internal Storage
The camera unit of the Xolo Win Q900s comes across as a better one when compared to the Lumia 630. The former gets an 8 MP PureCel rear camera with auto focus and LED flash and a 2 MP front camera. On the other hand, the Lumia 630 gets a 5MP rear camera without a flash and there is no front camera. Furthermore, the PureCel sensor by Omnivision is capable of capturing FHD 1080p video calls and saves the power of the battery to a great extent. The internal storage is 8 GB in both devices but you can extend the storage by 128 GB in Lumia 630, while the limit of expandable storage of the Xolo offering remains unknown. While we do not expect much of a difference when there is an expandable card slot, the Lumia 630 sounds more appealing with the extra large SD card storage support.
Battery and Features
The Xolo phone gets a 1,800 mAh battery that should last you a day with moderate usage the same is expected from the 1,830 mAh battery in the Lumia 630. The battery in the Xolo offering should be delivering a better backup as the handset has power efficient features. Both the handsets run on Windows Phone 8.1 and the Lumia 630 features SensorCore chip that helps users to keep a track of their health and offer results integrated with Bing Health and Fitness App and share the same with other apps.
Key Specs
Price and Conclusion
The price difference between the two smartphones is not too much and hence, you need to choose which one to buy based on the hardware that is appealing to you. The Lumia 630 has a slightly better processor, but the Xolo Win Q900s excels in the display and camera departments.
