Nokia has been hard at work over the last 2 years on its Lumia range, the culmination of which is a series that features breathtaking design that forms a high level of integration with the Windows mobile ecosystem. Nokia’s efforts to consolidate itself in the global market, and to a certain extent it has done that with the Lumia series. In a bid to gain further market share, it has set its sights on emerging markets, and targeting these markets with affordable mobiles that offer a high amount of functionality. It is with this in mind that it has launched the Lumia 620 last year and the 520 this year. Both mobiles are available for budget buyers, and make the most of what Windows Phone has to offer.
The Lumia 620 comes with a unibody polycarbonate body in a curved shell design that makes it fit into the palm of the hand very well. It has a contoured design that makes it look very sleek, and a highlight of the 620 is its interchangeable back covers. These covers also come with a magnetic sensor, so that every time you change a cover, the mobile detects the colour and changes the Windows Phone theme to match. It is this kind of detail that makes the 620 stand out against other mobiles, and makes it alluring to buy. The Lumia 620’s design leads it to be a little heavier, although that might be to its advantage as there are users who like the feel of a weighted mobile. Overall, the design consistency on the Lumia 620 is better than what we see on the 520.
The Lumia 520 features a lot of elements from the 620’s design, and as such both mobiles tend to look similar. The 520 features a matte finish, and comes with the same elegant design that makes it easy to hold in the hand. The iterative design that Nokia has undertaken with the Lumia series makes it easier to relate one model to the other, and that is a very good thing considering both the 520 and 620 share a lot of similarities with the stunning design of the Lumia 920. The design of both mobiles is very similar, and the only differentiation being the fact that the Lumia 620 is slightly chunkier and more robust, with the 520 being more contoured.
The Lumia 620 comes with a 1 GHz dual-core processor along with an Adreno 305 GPU and 512 MB of RAM, and although these might seem low-end, considering what budget Android mobiles come with these days, the Windows ecosystem is not as resource hungry as Android, and does a great job of making the mobile fast and lag-free. The internal memory is of 8 GB, and it can be extended to 64 GB through the micro-SD slot.
The Lumia 520 contains a 1.0 GHz dual-core Krait processor with Adreno 305 GPU and 512 MB of RAM, and has features similar to that of the Lumia 620. While the 520 is fluid when it comes to browsing and general navigation, it suffers when it comes to multi-tasking, with a noticeable lag of a second or so. However, this is barely noticeable and not something that restricts the usability of the device on a day-to-day basis. There is not much to differentiate the mobiles when it comes to internal hardware.
The Lumia 620 features a 3.8-inch TN TFT LCD panel at 800 x 480 for 246 ppi, and comes with Nokia’s ClearBlack technology, which greatly enhances the visibility of the screen in bright conditions. The ClearBlack technology allows you to get more detail without increasing brightness and contrast levels. Also, the 620 features Sensitive Touch that allows you to use the screen even with gloves on.
The Lumia 520, on the other hand, comes with a 4.0-inch IPS TFT LCD at 800 x 480 with 233 ppi pixel density. The screen is vibrant and has decent black levels with great contrast and viewing angles. The 520 comes with a sunlight readability mode, which is also seen on the 620, which boosts brightness so as to make visibility better. The 520 also comes with Sensitive Touch, which lets you use the touchscreen with gloves on. Both mobiles have decent screens for this segment, and there is not a whole lot of difference amongst the two
Imaging & Battery
The Lumia 620 and 520 have the same sensor, which is a 5.0 MP variant that allows video recording in 720p. The 520, however, lacks the LED flash that is there in the 620. Also, there is no front camera on the 520, and if video chatting is something that is essential for you, then you’re better off choosing the 620.
However, the 520 builds on what the 620 has to offer in the battery section by featuring a 1,430 mAh variant to the 1,300 variant that is available in the 620.
Overall, both the Lumia 620 and 520 offer a great set of features and are a good choice considering the amount they cost. The Nokia Lumia 520 price in India is currently Rs. 9715, while the 620 costs a little more at Rs. 12,878. Whereas the 520 has a slightly bigger screen and bigger battery, the 620 beats it in the imaging section by featuring a front camera as well as the inclusion of LED flash.
