Nokia has bridged several gaps with its Windows Phone 8.1 operating system. Users will now get Cortana Assistant which rivals Google Now and Siri along with added notification center and much more in the first Windows Phone 8.1 device- Nokia Lumia 630. The dual SIM smartphone will be priced in affordable price segment and the price will be very close to the existing Nokia Lumia 625. Let’s compare both of these smartphones to know the difference.

Display and Processor

Nokia Lumia 625 comes with a larger 4.7 inch IPS LCD display with lesser WVGA resolution which amounts to 199 pixels per inches. The display is protected by Corning Gorilla Glass 2.

The Nokia Lumia 630 on the other hand comes with a smaller 4.5 inch display with more 854 x 480 (FWVGA) pixels spread across it. The display is protected by tougher Corning Gorilla Glass 3 and sports Nokia’s ClearBlack technology for better outdoor visibility. Nokia Lumia 630 is the first Lumia phone with virtual keys and this means, further reduction in display real estate.

Nokia Lumia 625 is powered by 1.2 GHz dual core processor with more efficient Krait cores. The Nokia Lumia 630 on the other hand comes with 1.2 GHz Quad core Snapdragon 400 chipset with cortex A7 based cores. Both chipsets feature only 512 MB RAM and we can expect the performance to be similar for basic day to day task.

Nokia Lumia 630 however will have the advantage of 2 extra cores while performing more taxing tasks. It also comes equipped with an extra SenseCore which monitors fitness data including how many steps you have taken and how many calories you have burned. The data is logged in Bing Health and Fitness App. Nokia will also release the SDK for this app to developers.

Camera and Internal Storage

Camera features take a back seat on Lumia 630. The Nokia Lumia 625 comes with a 5 MP rear camera with LED flash, capable of full HD video recording and also a front camera for basic video chat and selfies. Nokia Lumia 630 eliminates the front camera and LED flash. The basic 5 MP rear camera can shoot only 720p videos.

Internal storage is 8 GB on both Lumia 625 and 630. However, Lumia 625 allows expansion up to 64 GB and Lumia 630 allows microSD expansion for up to 128 GB. Although both storage options are more than decent at respective price range and will suit most users. Nokia Lumia 630 scores more for 128 GB microSD support.

Battery and Other Features

Battery backup has rarely been an issue with Nokia Handsets. Nokia Lumia 625 offers 552 hours of standby time and 15 hours of 3G Talk time from its 2000 mAh battery and Nokia Lumia 630 will offer you 13 hours of talk time on 3G and 600 hours of standby time from its 1830 mAh battery. Music play back time however is considerably lesser at 58 hours on Nokia Lumia 630 compared to 90 hours on Lumia 625.

Lumia 630 will have a big advantage of Dual SIM support as compared to Lumia 625 in Indian market. Smart Dual SIM implies, you can receive call on one SIM even while attending call on another. Lumia 630 comes with new and improved Windows Phone 8.1 out of the box but this feature will eventually land on all Lumia phones running Windows Phone 8.

Key Specs

Conclusion

If you set aside camera features, Nokia Lumia 630 has better specs than Nokia Lumia 625 on paper. It has the added advantage of dual SIM but the display will be slightly smaller in size. Overall, both of these will be good performers but Nokia Lumia 630 seems a better choice out of the two handsets for now.

显示和处理器

诺基亚Lumia 625配有更大的4.7英寸IPS LCD显示屏，分辨率较低的WVGA，相当于每英寸199像素。显示屏由康宁大猩猩玻璃2保护。

另一方面，诺基亚Lumia 630配备了较小的4.5英寸显示屏，有更多的854 x 480 (FWVGA)像素覆盖，显示屏由更坚韧的康宁大猩猩玻璃3保护，并配有诺基亚的ClearBlack技术，提供更好的户外可视性。诺基亚Lumia 630是首款配备虚拟键的手机，这意味着进一步减少显示屏的实际面积。

诺基亚Lumia 625配备1.2 GHz双核处理器，搭载更高效的Krait核心。而诺基亚Lumia 630则配备了1.2 GHz四核Snapdragon 400芯片组，搭载了基于Cortex A7的核心。两个芯片组都配有512 MB RAM，我们可以期待它们在基本日常任务上的性能相似。

然而，Nokia Lumia 630在执行更复杂任务时将拥有两个额外核心的优势。它还配备了额外的SenseCore，可以监控健身数据，包括你走了多少步，消耗了多少卡路里。这些数据记录在Bing 健康与健身应用程序中。诺基亚还将向开发人员发布此应用程序的SDK。

摄像头和内部存储

在Lumia 630上，摄像头功能退居次要位置。诺基亚Lumia 625配备了一个带有LED闪光灯的500万像素后置摄像头，可录制全高清视频，还有一个前置摄像头用于基本的视频通话和自拍。诺基亚Lumia 630取消了前置摄像头和LED闪光灯。基本的500万像素后置摄像头只能拍摄720p视频。

内部存储均为8 GB，适用于Lumia 625和630。然而，Lumia 625可扩展至64 GB，而Lumia 630允许microSD扩展，最多可支持128 GB。尽管在各自的价格范围内，这两种存储方案都相当不错，并且适合大多数用户。诺基亚Lumia 630在128 GB microSD支持方面得分更高。

电池和其他功能

电池续航对于诺基亚手机来说很少是个问题。诺基亚Lumia 625提供了2000毫安时的电池，可提供552小时的待机时间和15小时的3G通话时间，而诺基亚Lumia 630将从其1830毫安时的电池中提供3G通话13小时和待机600小时。然而，音乐播放时间在诺基亚Lumia 630上明显较少，仅58小时，相比之下，Lumia 625可达90小时。

与诺基亚Lumia 625相比，在印度市场，Lumia 630有一个大优势，即双SIM支持。智能双SIM意味着，您可以在处理另一个SIM的通话时接听一个SIM的通话。Lumia 630出厂时配有新颖和改进的Windows Phone 8.1，但这项功能最终将集成到所有运行Windows Phone 8的Lumia手机中。

关键规格

结论

如果你不考虑摄像头功能，从纸面上看，诺基亚Lumia 630在规格上比诺基亚Lumia 625更好。它还具有双SIM的优势，但显示尺寸略小。总的来说，这两款手机都将表现出色，但就目前而言，诺基亚Lumia 630似乎是这两款手机中更好的选择。
