Build quality and durability
The Nokia Lumia 620 and 625 have very similar designs and build qualities. Like most Lumia phones they’re basically just colourful plastic rectangles. The Nokia Lumia 625 is slimmer at only 9.2 mm (compared to the 11 mm Lumia 620), but it’s also a lot bigger and heavier, coming in at 159 grams while the Lumia 620 is just 127 grams.
The Nokia Lumia 620 has a 3.8 inch 480 x 800 display with a pixel density of 246 pixels per inch. That’s not bad at all for a budget smartphone.
The Nokia Lumia 625 has a substantially bigger 4.7 inch display, but it keeps the same 480 x 800 resolution, leading to a pixel density of just 199 pixels per inch. Having such a big screen on a low end phone is great and almost unheard of. It’s also surprising as it’s a larger screen than even any of the high end Lumia models. However a 480 x 800 resolution just doesn’t cut it on a screen that size, so we’d actually take the smaller Lumia 620 over it.
The Nokia Lumia 620 has a 1 GHz dual-core processor and 512 MB of RAM, while the Nokia Lumia 625 has a marginally better 1.2 GHz dual-core processor and 512 MB of RAM. That’s not a huge amount of power for either handset to have, but Windows Phone 8 works surprisingly well on even low end devices, so it’s not such a problem.
The Nokia Lumia 620 has a 5 megapixel camera capable of shooting 720p video at 30fps. The Nokia Lumia 625 also has a 5 megapixel camera, but its video capabilities are slightly better as it can shoot 1080p video at 30fps.
Battery life, memory and connectivity
The Nokia Lumia 620 has a 1300 mAh battery capable of up to 330 hours of standby time, 9 hours and 50 minutes of talk time with 3G on or 61 hours of music playback. The Nokia Lumia 625 has a far larger 2000 mAh battery and can manage up to 552 hours of standby time, 15 hours and 10 minutes of 3G talk time or 90 hours of music, making it substantially better overall.
Both the Nokia Lumia 620 and the Nokia Lumia 625 have 8 GB of built in storage and support micro SD cards of up to 64 GB, so there’s nothing to choose in terms of memory.
There are a few key differences in the two handsets connectivity options. The Nokia Lumia 620 supports Wi-Fi, 3G, Bluetooth 3.0 and NFC, while the Nokia Lumia 625 supports Wi-Fi, 3G, Bluetooth 4.0 and 4G. So in other words the Lumia 625 lacks NFC but works with 4G, while the Lumia 620 has NFC but can’t be used on 4G.
Nokia Lumia 625 vs Nokia Lumia 620 – Conclusion
The Nokia Lumia 625 is better than the Nokia Lumia 620 in a number of ways. It has a bigger screen, a slightly faster processor, a marginally better video camera, has way better battery life and supports 4G.
On the other hand while the screen is big it isn’t any higher resolution than the one on the Nokia Lumia 620, so text and images will be a lot less crisp and clear. It’s also heavier than the Lumia 620 and it doesn’t have NFC, which the Nokia Lumia 620 does, not to mention the fact that it’s likely to retail for around £200, making it a good £40 or £50 more than the Lumia 620.
The differences in power and video camera performance are likely to be negligible, so unless you’re desperate for a big screen on a budget- and are prepared to sacrifice pixel density for it, we’d say that the only major selling point the Lumia 625 has over the Lumia 620 is that it can be used on 4G. If you want an affordable 4G phone it could be very tempting, as there aren’t many entry level handsets that support 4G, but for everyone else we’d say that the Nokia Lumia 620 is probably the better buy.
