Video Performance
In terms of video, the Galaxy Note 4 mainly benefits from the newer Snapdragon 805/APQ8084 SoC, and the addition of OIS. For the most part, there aren't any new video recording modes on the Note 4, as we see 4K30, 1080p60 and 1080p30 video available to the user.
For 1080p30 recording we see a 17Mbps bit rate with an H.264 high profile encoder. In practice I didn't really see any issues here, although on the exit sign at the end of the video there's noticeable aliasing
In 4K30 recording mode we see a 48Mbps bit rate with the same encoder as the 1080p30 setting. There's a significant increase in visible detail when compared to 1080p, but it seems that this mode is capped at a maximum of five minutes for video length and videos where temporal resolution is more important than spatial resolution will generally see relatively little benefit. EIS/video stabilization is also disabled for 4K recording, so OIS becomes quite critical for even casual video recording in 4K.
In 1080p60 mode we see a 28 Mbps bit rate with the same encode as in 1080p30. I don't really see visible detail degradation in this mode, and temporal resolution is clearly better than any of the other modes. This mode, as with 1080p30 supports EIS/video stabilization although using such a mode will reduce the field of view when compared to video with EIS off. One constant throughout all of these videos is the noticeably jerky nature of the OIS. It's hard for me to tell whether this is the result of an inability to damp certain motions due to the magnitude of the change or the OIS resetting itself during recording, but I suspect that this is a limitation of OIS that would require electronic image stabilization to compensate.

You have to love the 3DMark "onscreen" vs "offscreen" results. As long as any Android doesn't have to actually render images on the screen for the user than it is just as fast as an iPhone. ROLMAO.Announcer97624 - Saturday, November 1, 2014 - link
I don't get the point about battery life trailing behind the IPhone 6 plus? The IPhone 6 plus doesn't have a removable battery so on a 16 hour plane ride the IPhone 6 plus is a liability not an asset compared to the Galaxy Note 4's ability to have a few spare charged batteries. While I have the European Galaxy S5 4G LTE I have a battery wallet with six fresh batteries so I can go for most of a week without charging. My girlfriend has an IPhone 5 and is now going to purchase the Galaxy Note 4 specifically because of the non removable battery on all IPhones.Bikerboy89 - Saturday, November 8, 2014 - link
Wow onscreen GPU performance is laughable. Really bad vs the competition from apple and Nvidia. My LG G Flex gets better onscreen performance in gfxbench and the iPhone 6 gets double or triple Note 4. Pretty pathetic for a flagship device.MattL - Wednesday, November 19, 2014 - link
I finally realize why your color accuracy results differ so much from display mate, where you find the iPhone is more color accurate they found the Note 4 more accurate.http://www.displaymate.com/news.html#Color_Accurac...
"Recently some reviewers have published articles contradicting my Absolute Color Accuracy Measurements for the Samsung Galaxy S5. For example, see this recent review in phone Arena. The problem is that these reviewers are not scientists or display experts, and are using canned display calibration software incorrectly in order to test a display, which produces incorrect results and bogus conclusions. Below is a brief semi-technical analysis...
The Color Difference dE used by the Reviewers Incorrectly includes the Luminance: The reviewers are using retail display calibration software products that use a Color Difference measure called dE, which includes a Luminance (Brightness) Error component in addition to the Color Hue and Saturation (Chromaticity) Error component. Using the Color Difference dE is appropriate for setting the display calibration, but dE is Not a measure of Visual Color Accuracy (Hue and Saturation) because it also includes the Luminance (Brightness). The eye sees and interprets brightness and color as two separate visual issues - dE combines them together. So all conclusions based on using dE for Visual Color Accuracy are incorrect.
Our Color Accuracy only includes Color Hue and Saturation: Since the eye sees color and brightness as two separate visual issues I measure and analyze them separately. My published Absolute Color Accuracy measurements and data analysis includes only the Color (Hue and Saturation) Chromaticity Error component Δ(u'v') or d(u'v'), which evaluates just the difference in Hue and Saturation seen by the eye, and is plotted on a 1976 CIE Uniform Chromaticity Color Diagram in all of my articles. This is the correct method for evaluating Visual Color Accuracy (Hue and Saturation). Compare my very precise and detailed Absolute Color Accuracy plots with their crude figure."
Basically you're doing it wrong anandtech

this phone lags on ui and on games like deadtrigger2, don't trust benchmarks! specially when its samsung..... benchamrks are only meaningless numbers!(well useful in some cases)
