Speakerphone

The Note 2 puts its speakerphone in the same place as the original Galaxy Note, and thanks to the large size of the handset I bet there’s plenty of space for a big driver. The Note 2 also includes a new boost mode I didn’t see on Galaxy S 3 before that boosts speakerphone output volume considerably.

The tradeoff is that there is significantly more saturation and clipping with this mode toggled, but it is very, very loud.

Noise Suppression

Samsung has continually included Audience earSmart processors in its handsets for noise rejection and filtering, and the Note 2 is no exception. Both the original Note, and Note 2 include the Audience eS305 voice processor, though the Note 2 includes newer firmware thanks to its later release date. I’m told that both the Note and Note 2 were interesting challenges due to the extreme size of the handset and just how far apart the microphone pair is — there’s one at the very top, one at the very bottom on both models. In addition the T-Mobile Note 2 also has wideband AMR enabled (AMR-WB), which I confirmed inside ServiceMode by poking around. I called between two T-Mobile devices (the Note 2 and my own HTC One S) but it appears as though T-Mobile is still using AMR-NB over UMTS at least as evidenced by the 4 kHz maximum in the below spectral view. Either that or my HTC One S is the limiting factor.

Samsung is unique in that it gives a nice easy way to enable and disable the noise rejection paths by tapping the menu button, so we can easily test with it on and off just to see how much difference it makes. I’ve been supplied an industry standard babble track that emulates a loud cafe or restaurant, complete with a din of voices, doors opening and closing, and background bustle. I’ve found that playing this on loop in my office when I want that cafe vibe mitigates the desire to go and pay exorbitant amounts of money for the luxury of distraction, but I digress.

Anyhow I went ahead and tested the Note 2 with the babble track at a very loud maximum loudness of 94 dBA which is likely above spec, but a worst case. You can hear a dramatic difference between the Note 2 with the noise rejection turned on and off. I’ve heard eS305 do even better at rejecting literally all noise on the Xolo X900, but this is our first time using the babble track as opposed to music so my mental comparison isn’t quite fleshed out.

    Of course you could consider this an empirical display of the difference between Apple supporters and Apple haters. The Apple supporters don't seem to feel a compulsive need to wander into a non-Apple thread and tell everyone how much Android, Samsung, Google, AMOLED, S-Pen and TouchWiz all suck.

    Either way, yes, a thread that does't feel like a wanna-be gang fight between two groups of 8-year-olds is a pleasant experience!

    As owner of a 5" Dell Streak, I'm looking to replace it with another large phone and Note 2 seems just perfect. One question though: can I use another launcher (I don't like TouchWiz) without losing the S-Pen features? Reply

    I use Apex launcher, S-Pen stuff all works fine. :) Reply

    "we load webpages at a fixed interval until the handset dies, with display set at exactly 200 nits as always. The test is performed over both cellular data and WiFi. The new test has decreased pause time between web page loads and a number of JavaScript-heavy pages."

    What's the pause time?

    In such a test, the system that is fastest to idle will typically result in a lower or lowest power draw through time. One can only interpret the performance of a device relative to other devices when doing the specific test, maybe. No one should be assuming that they'll get 10 hours of wifi/cellular browsing though, whatever time your device of choice gets.

    Do humans really do what the battery life test does? I don't know if we're at the point where we are input saturated on how fast we can web browse, but I don't think we're at the saturation point just yet. So, if a phone downloads and renders web pages faster, I think we would just browse more pages in the same given time frame. The devices that burn more power during download and render times may end up with shorter battery life performance simply because a user is browsing more and faster.

    You guys are definitely promoting the idea of wider "dynamic range" on battery performance. The battery life test is perhaps a light use case based on my gut feel. Minimally, I think, at least for web browsing, the minimum battery life performance should at be established for devices.

    Lighter and lighter browsing workloads would tail off towards standby time. You may want to establish or guess at what the max work rate for humans is while browsing the web, like using an average reading speed or maybe somewhere in the 80th percentile of reading speed.

    Obviously, it's a more than one parameter problem with games, GPS, etc, but maybe that can be tackled later.

    Of all the smart phones I know about, this is the one I'm most interested in. However, I'm a Windows kind of guy, tried Android briefly and I certainly see why people would choose it over iOS, but in my opinion it's not great. Just my personal view, of course. I'm Windows trained and Windows is the most "intuitive" for me, largely because of that I'm sure.

    So, in case anyone from Microsoft is reading - can we get Nokia to make something like this with Win 8 as the OS?

    On Verizon? (I have to say though, Verizon's methodology for keeping their phones up-to-date doesn't thrill me. Of course, cell phones, particularly smart phones, are about as private as a house made entirely of screen doors anyway, so I'm not sure that's all that important as things exist today.)

    Got one this afternoon (not because of the article).

    My local store had them for 200 and also a 50 dollar mail in rebate. I dont think thats nationwide though.

    I like it, made an informal review in the forums.

    Really, you have a Note 2 without split screen functionality? So you cannot see and work with 2 apps at the same time??
    Thats weird! Here in Holland I cannot walk the street without seeing billboards showing off this feature.. those Apple fans don't know what hit them.. firstly iOS 6 wich feels like 2010 version of Android for Android users, now this Note 2 can even show 2 apps at the same time, side by side!

    Really weird the US versions don't have this firmware yet. But like you said in other reviews, US market is totally different. Here we see Samsung phones, in the shops, there you see AT&T or T-mobile or Verizon phones. Although here in NL almost always sold with subscription, and with the name of your provider on it, at least its an actual Samsung phone and not a T-Mobile phone..

    What? They're all still Samsung/HTC/etc branded in the US... What are you going on about? The carriers do meddle with updates and the firmware, but the thing isn't sold as an AT&T Galaxy S or something, it still says Samsung and it's advertised by Samsung (for better or worse, their anti-Apple commercials are almost as bad as Apple's old anti-PC commercials)...

    Hell my Sprint HTC EVO 4G LTE doesn't even have Sprint silkscreened anywhere on the front (amazing show of restraint on their part). AT&T's often the worse about branding, they've put the name AND logo on some Moto phones (centered no less).
