Video Performance

By moving from the 4:3 8MP sensor in the Nexus 5 to a 4:3 13MP sensor, Google has been able to enable UHD (3840x2160) video recording on the Nexus 6. Google can also benefit from improvements in Snapdragon 805 allowing for higher quality video encoding. With Snapdragon 805 only capable of HEVC decode, we're still looking at H.264 encoding on videos for the current generation of devices. Unfortunately, Google does not include a 1080p60 recording mode on the Nexus 6, so both 1080p and UHD recording modes are at 30fps.

For 1080p content the Nexus 6 encodes with an average bitrate of 17Mbps and uses the Baseline H.264 profile. I don't know why Google isn't using the Main or High profile for their video recording, as Baseline is typically used in applications like video chat where quality isn't a big concern. I have no complaints about the quality of the video itself, although the OIS doesn't do as much to reduce the shake in the video as I imagined it would.

UHD video is encoded with an average bitrate of 42Mbps, and is again Baseline H.264. Compared to the 1080p video there's a significant increase in overall detail, particularly with the branches of the trees and smaller objects like leaves on the ground which tend to show up as large blurry areas in the 1080p footage. Something I noticed when testing the UHD recording on the Nexus 6 is that it has a tendency to drop frames, which is demonstrated in the video below.

As you can see, there are a few areas where the video framerate dips below 30fps during a fast movement, and several moments where the video will stop and then skip forward. I haven't been able to determine a cause for this, but Samsung and other OEMs have been able to do UHD recording at 30fps on their devices that use essentially the same hardware as the Nexus 6 which leads me to believe it's an issue that is rooted in software.

    I'm still deeply in love with my Nexus 4 despite it being two years old, but the 16GB storage is starting to chafe a bit. I'll be looking at trading up, selling the N4 to fund a 32GB Nexus 5. It's a better phone in practically every way and I really think LG did a fantastic job on both the N4 and the N5.

    The N6 is just... really, it's confusing. I don't get it. How could they fuck this up?

    I felt the same way about my Nexus 4 but after water damage I purchased the Nexus 6 as the N5 was no longer available from the Play Store. I rooted the N6 for the notification light and Titanium Backup, turned off ambient display, installed brightness pro (quick manual control from any screen with one touch), and I'm loving the device. I get about two days worth of battery without playing games. I'll admit It's taken me about a week to get use to it but now it's easily my right hand and going back to the N4 in a way seems silly.

    My wifi connections and cellular signal with T-Mobile has been solid. I’ve noticed only one issue and that’s within the first 10 seconds after the phone has restarted there's a slight delay (I think it's the encryption being initialized) but after that I think the update 5.0.1 has resolved the encryption speed as the phone is as fast if not quicker then I am.

    If you're happy with your N4, keep it it’s a good device. My N4 ran Loliopop very well except for the random daily reboots which I haven’t experienced on the N6. If you upgrade to the N6, I think you'll find it's a great device too even if it first comes off as confusing. My only caveat would be smaller hands and if you wear tight pants with small pockets. I'm 6'3" - 6'4" with above average fingers and can use this device one handed. I can see where people with smaller hands may run into handling issues. This device fits very well in my front pockets too. A little snug when wearing jeans but still completely manageable.

    I was bothered by the N6 at first but now after owning it it’s easily my favorite Nexus to date. I use my N6 more then my N7 and with it rooted for the notification light (Light Flow) it’s like having by N4 back but better, much better. Don’t throw the N6 out yet, it’s turning out to be a solid device that’s now become my digital right hand. If you give it a chance I think you may find the same to be true.

    How anyone could ever go from a Nexus device with stock Android to a Samsung phone running that TouchWiz garbage amazes me.
  • grayson_carr - Thursday, November 13, 2014 - link

    Same. Samsung owners are always going around talking about how fast their phones are... no lag, no slowdowns, perfectly smooth, etc, but every time I go into a store to play with a new Samsung phone on launch day, it feels slow as hell, dropping frames left and right, compared to my Nexus devices. The GS5 and Note 4 are no exception. Maybe Samsung phones feel fast compared to older phones, especially older Samsung phones, and maybe that's why so many people think they are fast, but they just don't perform at the same level as modern Nexus, Motorola, and HTC phones. If they did, I would have a Note 4 in my pocket right now, because I love the camera, screen, and build, and I can live with the cluttered and slightly garish software.

    Change the launcher
    The Note 3 SMOKED the Nexus 5
    The Note 4 SMOKES the Nexus 6
    And it's NOTHING to do with the 'hardware' as it's essentially the same. That said, something in the software isn't allowing the Nexus 6 to run ANYwhere nearly as quickly, efficiently and smoothly as ANY other Android flagships. Period.
    That was the same issue with the Nexus 5 ( that and the shitty camera )

    Wish there was an edit ...
    Because you're essentially admitting TouchWiz is superior to 'stock' Android. TouchWiz @ release was trash. Through the release of the G3--->& everything but the kitchen sink.
    Since then with the S4 & 5, Note 2, 3, & now 4---> Samsung's spent MORE time developing the compelling features of TouchWiz while elimating the 'duff'
    The carriers and their bloat ass to the crap. I've owmed them all, and when it comes to 'large phones' or phablets, there's not an equal to the Note 4

    You'd have to go really far back in history to find trash TouchWiz. TouchWiz had a hardware accelerated UI on the GS2. Yeah, that was with Android 2.x. I agree the TouchWiz Samsung used on the original Galaxy S needed a lot of tweaking, thanks to horrible choices of file systems and really sloppy colour and sound calibration. But since the GS2, I've never felt the need to root a Samsung phone.

    Far back? TouchWiz has noticeable user experience impact ON THE NOTE 4

    Samsung zealots simply don't notice or are in denial, but anyone objective IMMEDIATELY sees it.

    When you go to swipe to the left and your 8 core desktop level phone pauses? That's not normal just FYI. Benchmarks don't tell that tale.

    TouchWiz has REAL WORLD performance impact in exchange for zero benefit

    Yes you can change launchers, root the phone, install hacked ROMs, and get a PhD in phone. Or you can just avoid Samsung

    Eh, I've gotta' say I feel extremely satisfied with buying a Nexus 5 (yes, 5) last week.
  • grayson_carr - Thursday, November 13, 2014 - link

    If Google put a slightly larger battery and the camera from the Nexus 6 in a revamped Nexus 5, I would buy it in a heartbeat. The processor, RAM, and screen are shockingly all still great, even a year in. It's still as fast, if not faster in day to day tasks than the Nexus 6 (and pretty much every other phone), and the sub pixel density of the screen is actually higher than the Nexus 6, not to mention much better brightness and color calibration!
