Samsung Galaxy Nexus & Ice Cream Sandwich Review
by Brian Klug & Anand Lal Shimpi on January 18, 2012 1:34 PM ESTBattery life remains the other big axis on which smartphones are judged, and here we've turned to our regular 2011 suite of battery life tests to see how the Galaxy Nexus shakes out. Our battery life testing consists of a page loading suite which loads through a few dozen pages endlessly on both WiFi and cellular data until the phone dies, with the display set at 200 nits. For the cellular tests, we're always careful to test in cellular environments with decent signal (at least -75 dBm or higher) as well, since that's a factor. Next is a simple call test where we play music at both ends of a call until the device under test dies, and our final test is a WiFi hotspot workload which consists of four page loading tabs and a 128 kbps streaming MP3 station that runs until the phone dies.
First up are the web browsing tests over cellular 3G; this means EVDO Rev.A for the CDMA/LTE version, and WCDMA T-Mobile for the GSM/UMTS device.
The Galaxy Nexii both do surprisingly well. I'm actually very impressed with how long the devices lasted subjectively on 3G and this definitely backs that up. Of course, both devices include beefy batteries, but Samsung has done a nice job thus far including big batteries without making devices bulky or heavy.
Next up is the same test, but on 4G LTE for the CDMA/LTE variant.
The Galaxy Nexus doesn't post numbers very far in front, but manages to come in the top of the pack on 4G LTE at just under 4 hours. This is a pretty impressive result, honestly, considering that CMC221 is likely made on the same 45nm manufacturing process as CMC220. Again, I'm impressed with the Galaxy Nexus' longevity even on 4G LTE.
Surprisingly, the Galaxy Nexus can't break past that 6 hour mark even on WiFi, however, which does lead me to think we might be constrained by driving that display.
If you ever wanted to see how much difference having a different cellular architecture makes, see above. The GSM/UMTS Galaxy Nexus lasts impressively long on a voice call, at over 11 hours, yet its CDMA/LTE brother lasts just over half that.
WiFi hotspot on 3G tells the same story - I'm not sure what Via Telecom's CBP7.1 draws in its active state for EVDO or 1x voice, but it seems to eat up more power than the XMM 6260 (X-Gold 626) in the GSM/UMTS Galaxy Nexus.
As a 4G LTE WiFi hotspot, the Galaxy Nexus loses its edge over the Revolution, but does come in just ahead of the rest of the 4G LTE herd.
The story of battery life on the Galaxy Nexus unsurprisingly depends on which variant you're talking about. For a phone with a 4.65" display, I'd say I'm impressed with the battery life on both devices - remember that the area that needs to get lit up goes as r^2 - increasing that and not killing the battery is a big feat. In addition, I'd wager that using the OpenGL ES renderpath (and accelerated browser in 4.0) definitely helped both Galaxy Nexus devices post impressive scores. As for the two variants, the GSM/UMTS device has impressively long battery life pretty much across the board. Playing with that phone, I was rarely wanting for more on my regular use schedule (I charge at night on my nightstand). We've seen XMM6260 before in numerous devices where it seems to be a pretty good citizen.
The CDMA/LTE variant, on the other hand, depends strongly on what air interface you end up using most - on 4G LTE the device comes in at the front of the pack usually, and its 3G web browsing test is above average. However, if you make a lot of voice calls, the phone might not cut it. Unsurprisingly the CDMA/LTE Galaxy Nexus does nothing to dramatically change 4G LTE battery life - for that we're still waiting for upcoming 28nm LTE basebands.

Interesting. I originally picked S5K4E5 family as being the likely choice - as it's the BSI equivalent, and though that was what was inside until I decompiled/dug around inside the ducati-m3.bin file as noted in the review.You'll see numerous references to "S5K4E1G" and none for "S5K4E5" which is the BSI version. EG:
"CSI.COMPLEIO ¿F¿MSP.NEW_SENSOR ¿S5K4E1GA ¿F¿S5K6A1GX03 ¿MSP.NEW_LENS ¿F¿VM149C ¿MSP.NEW_CSI CSI2A ¿FCSI2B"
It could very well be BSI since they've x-rayed it.

Official Samsung site says SGS II has quad band 3G and Galaxy Nexus has penta-band 3G, so there's a difference in GSM connectivity:http://goo.gl/gvIWV

I appreciate the thoroughness in this review, Anand.Interesting, however, how I find so many things about the software completely irrelevant to someone who just can't leave things vanilla. Browser performance and features, launcher scrolling, screenshots, on-screen keyboard, etc. None of those things are in their original Android form on my phone (SGS2). Some issues have been addressed by Samsung, some by XDA developers, some by myself. As a result, I believe I have the perfect phone on the market (for me). Reading every section of this article, I kept finding myself thinking, "Heh, my phone doesn't have that problem," or, "Mine does that even better," or, "would suck to have that phone instead of my Galaxy."
I always thought advancement in tech = replacing devices sooner. However, after reading this review, I have no desire whatsoever to replace my current phone with the new flagship. I always get that feeling when I read a video card review, CPU review, SSD review, etc. But I feel like my phone lacks nothing, and I will stick with it for a long while. Customizing and tweaking software to your own taste, making it feel just right is the most important aspect of an electronic device that provides so much interaction. I guess that's why I almost feel handicapped on a stock Android phone or, especially, iPhone. The devices just feel so clunky and unrefined.
Thank you, if nothing else, for helping me see a different perspective on things :)

1. Can you re-check and confirm if swiping tabs off in the task menu, actually KILLS the apps, or it just takes them off the list? Because I've heard before that it doesn't kill them.2. The battery tests, especially the Wi-Fi ones, were they done with 3G and LTE on?

"At 720p, which happens to be the GN's native resolution, the OMAP 4460 is a bit faster than Tegra 2 but not significantly so. The more important thing to keep in mind is just how much faster Tegra 3's GPU is by comparison"I don't understand this remark. The chart that's posted for the 720p offscreen renders don't have a Tegra 2 device. In the RightWare charts the Galaxy Nexus scores much more than "a bit faster" than the Tegra 2 devices. And to my knowledge no Tegra 2 smartphones are offered at native 720p resolution.
I also checked the AT Bench database and couldn't find any Tegra 2 benchmarks to compare. Do you guys have some unposted numbers?

You guys do a great job. Love the attention to detail in your review. Thanks.DrKlahn - Thursday, January 19, 2012 - link
I found this comment interesting. I have had the phone since launch day (VZW) and have yet to notice any lag hitting the virtual buttons. Perhaps I am just not as sensitive to it or some other process on your test phone is affecting it. I have got the phone to lag doing some very intensive tasks on occasion, but it's very infrequent. My chief complaint has been the volume which I remedied with a free app (Volume+ with the +2 setting). Otherwise I give the phone very high marks. I have no real desire to root or tinker with it yet, the stock experience is excellent.peokuk - Thursday, January 19, 2012 - link
for the font comparison, why not 'the quick brown fox jumps over the lazy dog'? using cat and jumped leaves out the letters 'g' and 's'...http://en.wikipedia.org/wiki/The_quick_brown_fox_j...

No one has actually said it yet so I will. Good review guys, in depth and informative as always.Thanks for your hard work.

Actually, someone already has! Seems the internet is not completely populated by haters. :)
