With the announcement today by T-Mobile of the Lumia 810, the question that follows next regards differences between it and the Lumia 820.
At first glace you may think that these are the same phones just with a name change. But they are not.
While the “guts” and main features are overlapping, the physical design of the 810 is more “blocky” than the Lumia 820. In addition, the sizes of the devices are slightly different as well, with the T-Mobile 810 being slightly larger, but weighing 15 grams less.
Finally, talk-time is also rated higher with the Lumia 810 boasting a 10.2 hour span versus the AT&T Lumia 820 at just 7.5 hours (both over 3G). The key difference is because the Lumia 810 has a slightly larger battery (1800 mAh) than the AT&T Lumia 820 (1650 mAh).
Hopefully we’ll have more on the subtle design differences soon. But as we can see, Nokia is able to adjust slightly their phones for carriers, giving each an “exclusive” device while not compromising too much in terms of appearance or features.
We predicted this to be the case in our earlier editorial where we speculate about Verizon's Lumia 822.
