EVGA Tegra Note 7 Android 4.3 Tablet Review

Camera Performance and Battery Life

The Tegra 4 features computational photography capabilities, dubbed Chimera, which can enhance images captured on mobile devices in real-time. For example, with Tegra 4, HDR photos can seamlessly be captured without the lag associated with current solutions. The Tegra 4 effectively captures two images simultaneously (at high and low exposures) to produce the HDR images. Current solutions capture two images as well, but there’s a lag between the captures, which can result in strange artifacts if there’s any motion in the frame. The Tegra 4’s computational photography capabilities are also be able to handle HDR panoramas, strobe motion captures, 3D reconstructions, and object tracking.



As we mentioned earlier, the rear-facing camera on the Tegra Note 7 has a 5MP sensor. When used in conjunction with NVIDIA’s special sauce, the camera is capable of capturing some pretty good images, but not all of the time.

If you take a gander at the samples, you’ll see what we mean. We found that the Tegra Note 7’s camera had some trouble focusing in less than ideal lighting conditions. Outdoors or in well lit areas, however, the Tegra Note 7’s camera does a pretty good job, as evidenced by the shots of the plants and tree branches. Colors are slightly under-saturated, but that’s an easy fix with any image editor. Though it isn’t perfect, for a tablet camera, the Tegra Note 7’s isn’t bad.

HotHardware Battery Life Test
How Long Does It Last?

As is the case with any mobile device with a high-res screen and quad-core SoC, battery life can sometimes be an issue. NVIDIA claims the Tegra Note 7's 4100mAh battery can offer up to 10 hours of battery life during HD video playback. To take the Tega Note's battery to task, we opted for a controlled "worst case scenario" battery test with AnTuTu Tester.

The Tegra Note 7 didn't fare very well in this test. We tested the device in its default "balanced" configuration and with its power saving features enabled (which limits the Tegra 4 SoC to 2 active cores). In balanced mode, the Tegra Note 7's score of 346 trailed all of the other devices. In power saving mode, however, the Tegra Note 7 finished in the middle of the pack.

Please keep in mind, however, that this test is worst case scenario, and that higher-performing SoCs are likely to kill a batter quicker when running at full bore.  During normal use, we had absolutely no trouble getting the Tegra Note 7 to last more than 2 full days, which including a mix of gaming, browsing the web, and running social networking apps like Facebook and Twitter.  We do not think battery life with be an issue with the Tegra Note 7 for consumers shopping for a 7" tablet.
