Windows Budget Phones: Nokia Lumia 620 vs. Lumia 510
The Nokia Lumia 920 is a pretty smartphone but its price tag (although not that expensive) might be too much to some. Thankfully, there are two other Windows phones that are quite good but at much cheaper prices. Meet the Nokia Lumia 620 and Lumia 510, two smartphones that thrifty anti-Android/iPhone people might like. You don’t want to buy both of course so we will see which between the two is the better one.
Looks
Hardware
Although these two phones have displays that have the same resolution, the Lumia 620 present images and texts better. This is because the Lumia 620′s display has a higher color count (16 million) than the Lumia 510 (65,000). This also means that the 620 has better color accuracy.

The Lumia 620 also has the better internal components. Its dual-core processor simply outmatches the 800 MHz Qualcomm chip on the Lumia 510. The Lumia 620 doubles the RAM of the Lumia 510 which further confirms that the former is faster than the latter.
If you are particular with storage, you might want to steer clear from the Lumia 510. It only has 4 GB of internal memory while the Lumia 620 has 8 GB. What’s more is the Lumia 510 doesn’t support microSD! That means you are stuck with that 4 GB storage while you can extend the 8 GB storage of the Lumia 620 to a maximum 64 GB.

Software
One runs Windows Phone 8 while the other hosts Windows Phone 7.5 Mango. Continuing our trend, it’s pretty clear that the Lumia 620 runs WP 8. The Lumia 510 simple does not have enough processor power and RAM to handle the newest mobile OS from Microsoft. This also tells that the Lumia 510 will never run WP 8.

Battery Life
The Lumia 620 and Lumia 510 have batteries that are rated at 1300 mAh. They are not the same battery though. The Lumia 620 is tested to last up to 10 hours of talk-time while connected to the 3G network. This is equivalent to 14 hours and 40 minutes on 2G. The Lumia 510 has a shorter battery life: 8 hours and 52 minutes in 3G or 6 hours and 15 minutes on 2G.

Connectivity
Both phones support HSPA connectivity but the Lumia 620 has better download speeds. The Lumia 510′s download speed peaks at 5.76 MB/s while the 620 can reach 21 MB/s. The Lumia 620 also supports dual-band Wi-Fi. This means it can shift to the 5 GHz Wi-Fi band (if available on your network) which has less traffic and faster connection.

Bluetooth is present on both but there’s not version 4. The Lumia 620, interestingly, offers NFC. This technology allows you to use your phone like a credit card.The Lumia 510 matches this technology with FM radio (which isn’t available on the Lumia 620).
