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.

Why even bother posting a review of a phone that is over a month old? If you want to be a real news /review site you should of had a review the next day. There is no reason not to. period.get your shit together

Because they go more in depth than most reviews out there. The ones that post reviews the day after a product launch don't find nearly as many flaws and details as the AT team. There are plenty of other sites for quickie reviews, I like Anandtech for in-depth.Omid.M - Sunday, January 22, 2012 - link
That's unnecessarily harsh. If you're used to the same day "reviews" of Engadget--i.e. NOTHING technical, totally subjective measurements of everything, in the name of being the "first" with a review--then go ahead and keep reading Engadget.Brian and Anand review EVERYTHING in depth: basebands, screens, software, they even have supercurio who is well known dev in Android community for his take on audio processing. Plus, Anand and Brian were covering CES.
Anand, Brian,
Great job as always. I have a chance to pick up a Nexus LTE for $500 (since I don't have an upgrade) but will hold off; might go with iPhone 4S until Krait or iPhone 5 comes out and (hopefully) blows me away.

Why even bother posting a comment if you're not going to read the review? A cursory perusal of the index alone would have answered your question.Anand & Co. take the time required to turn in top-notch, in-depth reviews, and they've been doing it for longer than your favorite gadget review site has even been in business. Anandtech is, in every sense, a *real* review site.
If wholly subjective reviews of devices (provided within hours of launch) are your idea of informative reading, then please return to Engadget or whatever site you strayed from. Unlike Anadtech, sites of the sort you're looking for are a dime a dozen, and you'll find them substantially better suited to your attention span.

Can Brian or Anand comment on why they believe Samsung used an OMAP 4460 when they only clocked it to 4430 levels? Also, devs at XDA are having a hard time overclocking it to the 1.5GHz/384MHz max values. Any ideas? Thanks! -JamieTripp1717 - Friday, January 20, 2012 - link
Ive had it for over a month now and i upgraded from a galaxy s (epic 4g on Sprint). Watching Blue ray movies i put on my phone are simply amazing. Ive never seen anything better and i work in the electronics dept at sears. Its better than the samsung 7000 led screen. Overall it took a few weeks to really get used to Andriod 4.02 but it is an amazing improvment from 2.3.5. I cant think of too many flaws here. LTE is SOOO much fater than WiMax! i get about 25-30 MB/s when using speedtest. Upload speeds are very fast too, ave. is around 10ish MB/s. Battery life is fantastic compared to my epic 4g. At work i set my ohone to data restrict so i only get calls and texts because in my store there is NO signal at all and after 8 hours from 100% it will drop to 85%. My Epic wouldnt make it through the work day. 720p Super AMOLED+ really makes this phone a winner. Google and samsung working together is a great combo. My ONLY complaint is i wish i had an 8 or higher megapixel camera. But with the added features its pretty darn decent. No complaints except there are a few programs that are still not compatible with 4.0+ (HBOGO). I highly recomend this over any phone out or anything slated to come out for awhile anyways.Amit P - Friday, January 20, 2012 - link
I'm waiting for my THIRD Nexus to come in. I had screen problems with the first two. The screen wasn't as bright as my brothers Nexus with the same settings. The colors weren't as vivid either.Bristecom - Friday, January 20, 2012 - link
Thats why I didnt exchange mine. Even though it has a dead pixel, aside from that, the screen looks great. So I fear getting one with no dead pixels but poor brightness or colors. This screen is the best Ive ever seen. Other super AMOLED plus displays Ive seen have off colors that bother me.Bristecom - Friday, January 20, 2012 - link
I have to say, mine has a dead green subpixel and it is very clear to me even from a distance with green or white screens. Regardless, I didnt bother exchanging it. -Sent from my Galaxy Nexusmedi01 - Saturday, January 21, 2012 - link
A question, I have Galaxy S so can't compare.Could you please comment on whether black is actually black on Nexus as it is on Galaxy's?
I'm asking because dear objective Anand managed to make a photo of it that makes it look gray ("Display" page)
