Windows Phone 8X
With a smaller
battery, but the screen is smaller (less pixels), we are looking forward to
seeing how the Lumia 820 managed to cope with the tests of WPBench processor.
We are currently using the test applications that are not calibrated for
Windows Phone 8 just yet, so we suggest that you look at these figures with
your skepticism. Battery life is slightly shorter on rival Windows Phone 8
devices; probably due to the smaller 1650mAh battery. At least users have the
option to carry a spare battery. However, the smaller screen meant that we
recorded a longer battery life compared to the rivals during the process of
typical use. For more than one day, we were not worried about the charging, and
when necessary, the ability of wireless charging was there. Like the Lumia 920,
charging on the pad was not as fast as USB charging solution, but at least the
future is going to appear here, slowly.
There is not much for us to be surprised,
the results of our test corresponded with the Lumia 920 and HTC 8X (all three
phones run on the same dual-core Snapdragon S4). SunSpider test results
continued the trend of Windows Phone with the scores of less than 1000ms, while
AnTuTu’s results were on par with the other Windows Phone devices we've seen so
far. Packing the same processing power as the two leading Windows Phones, the
Lumia 820 proved to be very fast, with websites, games, and video transmitting
applications that were loaded quickly and had no problems. Mapping applications
(granted power by Nokia data) quickly discovered our position and drew a
roadmap to where we were searching- and we make sure that the A-GPS and GLONASS
supports do not cause any damages.
The quality was spoilt by the screen
resolution when playing back video, which will not give you anything in 720p;
although the audio playback was certainly quite important. At least the current
applications (designed for the same 800x480 screens) did not seem out of tune.
Call quality was reliable as ever from
Nokia, with two "distortion-free wide amplitude" mics that take care
of audio quality on calls and video capture. In our model, we found that the
average download speeds were about 6Mbps on HSPA, while upload speeds were
generally less than 1Mbps on our O2 UK SIM.
Conclusion
If you have still concerned with joining
the Windows Phone 8 ecosystem, the Lumia 820 is a hard item to sell. While the
off-contract price is significantly cheaper than the 920, the price difference
is so small that we cannot recommend it. The screen is spoilt by a resolution
of the last generation and the camera (while not unattractive) does not put up
the advanced technical skills of the 920.
The
disappointing screen
The screen is smaller than the Lumia 920,
but the hardware does not feel much lighter. In terms of its strength, a
replaceable battery is for the savvy users and the inclusion of microSD
storage. Nokia’s trend of eye-catching color schemes will help these phones
stand out from the hardware designs that are more secure and the inclusion of
the free wireless charging panel and housing is an additional welcome. But we
would prefer to pay more to get the Lumia 920.
