- Frame rate issues for more intensive apps
- Not full HD display
- Poor viewing angles in bright light
The Lumia 830 will be the one of last Lumia phones to sport the Nokia label now that Microsoft has taken over the Finnish company. Marketed as an "affordable flagship" the 830 offers many of the same features as on the 930 such as an aluminum frame and colorful, interchangeable plastic back panels. Where it differs though is its size. It is slightly smaller and thinner measuring in at 5.5x2.8x0.3 inches and weighs grams. On paper the difference might be small, but reviewers noticed a significant change when switching from the 930 to the 830. Anand Tech states, "The 930 would slightly dig into my hands…the Lumia 830 does not…In hand feel is very good."
Nokia has opted to keep the same 5-inch screen size, but in their quest for affordability they had to go without a full HD screen and instead opting for 720p. While this offers a slightly lower pixel density of 294ppi, most critics had no issues with pixilation thanks to the ClearBlack IPS technology. They describe the overall panel as "punchy" with excellent viewing angles, deep blacks and good bright light legibility, though CNET did notice a significant drop off in legibility when changing angles.
On paper, the 830 doesn't seem impressive with only a 1.2GHz quad-core processor and 1GB of RAM. With that said experts add that its performance didn't leave much to be desired as apps launched and closed quickly, navigating the UI was fluid and most games played stutter-free. Battery-life as well impressed reviewers, especially since Nokia opted for only a 2,200mAh battery. When put through the battery draining tests, it lasted a little over 10 hours and real-life usage got most experts through a full day of moderate usage. Just in case you do run out of juice, the battery is removable so you can swap out if necessary.
Like the other Lumia phones, the 830's main event is the camera. At 10MP, it might not offer the same sharpness as the 1020's 41MP camera, but it still holds its own against its competitors. Branded as PureView, the 830 comes equipped with Optical Image Stabilization for clearer pictures. When put to the test, experts were able to take high quality pictures with accurate colors and plenty of detail in bright light situations. Unfortunately, they also experienced a significant quality dip once the lights dimmed in the form of noise, loss of detail and muted colors though the images weren't necessarily unusable.
While reviewers generally enjoyed the Lumia 830, they are hesitant to recommend it outright. Trusted Reviews states, "The Lumia 830 is, mostly, a very good phone, but before you buy you need to make peace with some tricky weaknesses." TechRadar adds, "With a cheaper price tag than its flagship brother, the Lumia 830 can be forgiven for taking a few cuts in performance...[but] I really struggle to see how the Lumia 830 will compete."
