Since the RAZR Review

The Droid RAZR and RAZR MAXX as of this writing have been both pushed the same “6.12.173.XT912.Verizon.en.US” update, which makes a number of changes and improvements that mitigate some of the things I complained about in the initial Droid RAZR review. The core Android version is now 2.3.6. I’ve re-run our performance tests, and nothing has really changed here, unsurprisingly.


First, the update changes the Settings page aesthetics slightly, including some icons that weren’t there previously. There’s also a change to some of the other icons on the home screen, and the cDRX features I’ve written about before.

I noted some frustration with the RAZR’s camera app in the original review, this has been significantly improved in the latest update. Stability is much improved, UI items no longer completely disappear and the camera app hasn’t crashed at all. In addition I no longer see the RAZR miss focus entirely like I did before, which was a big problem at times.


Some other OEMs have written about GLONASS support on their hardware, and I forgot to note in the initial RAZR review that this device also includes GNSS (GPS+GLONASS) support the same way courtesy the MDM6600. Until recently basically all satellite based location has used GPS, which consists of a constellation of 27 satellites. GLONASS is its Russian cousin, with 24 satellites. The two can be used in conjunction to get faster 3D fixes, better coverage, and greater accuracy. We'll see more and more GNSS solutions start shipping in 2012 as well.

GLONASS satellites are used here, circled in red

If you fire up GPS Test, satellites numbered 65-88 are GLONASS. Qualcomm’s GNSS only uses GLONASS when there either aren’t enough visible GPS satellites for a fix, or SNR is bad (basically an urban canyon or indoors scenario), so you’ll often see a set of bars pop in or out depending on how good the normal GPS SNR is. This implementation is the same for all of the Qualcomm SoCs and MDMs that include GNSS support.

Final Words

If you want a smartphone that’s uncompromising about battery life and also includes 4G LTE connectivity, the Droid RAZR MAXX is a no brainer, especially over the Droid RAZR sans MAXX. There’s just no other device out there right now that lasts as long and isn't a feature phone or crippled in some way, and in a world where everything is being fabbed on a 4x nm process, battery life at the high end is entirely a function of battery capacity. Until 28nm SoCs and basebands start arriving in devices later this year, things aren’t going to change much, either - you just need a big battery to post the kind of numbers the MAXX does in our battery life tests.

The RAZR MAXX is a device after my own heart, as I almost always end up buying or seeking out whatever extended battery option is available for whatever device I carry. There’s just nothing more frustrating than constantly worrying about having a dead device with no charger in sight. On trips and visits to cafes with intermittent or barely working WiFi, hotspot battery life ends up being probably the most important thing to me, and remains the big battery life equalizer. 

Right now on Verizon the top tier of Android phones in my mind really is a two horse race. On one side is the Galaxy Nexus which is awesome purely because it’s running Android 4.0 with no customizations. On the other hand, the RAZR MAXX is a device with very similar specifications (and the same CPU, GPU, and clocks), but with a much larger battery. That's a big simplification, but superficially those are the biggest factors. As soon as the RAZR MAXX gets its Android 4.0 update, I think it’ll be hard to argue in favor of the Galaxy Nexus over the MAXX for most customers, though the former will continue to be the platform that gets updates first, comes with an unlocked bootloader, making it the obvious enthusiast choice. For people who don't find themselves presented with a charger at the end of every day, or can't charge the device on a regular schedule, the MAXX is also a no-brainer. 

If anything, I hope that the RAZR MAXX sets a new trend for devices with internal batteries, which a lot of recent devices have started shipping with. If you’re going to make a device and seal the battery inside, at least make it huge.

Battery Life, Tested

    Thank you for another great review.
    As I was browsing through the phone benchmarks in the database the other week I noticed that this phone was listed there. Just out of curiosity, why was the benchmarks uploaded there before the review?

    Best regards

    Our backend is completely integrated, in this case our Bench system is tied into our graphing system. So we'll typically put a new product in Bench and then generate graphs from that, in which case if we don't set it to private mode it will show up in Bench before it's in an article. Reply

    I see.
    Thank you for the reply.

    Best regards

    When will Motorola release a GSM version of this awesome device?? Waiting with my fingers crossed! Reply

    I really hope they do as well, but there's no official word on when that device is coming.

    Well, its a start anyway. The device really isnt that much bigger. There is no reason why every device cant have at least 12 hours of web time. Unfortunately this translates into only two maybe 3 hours of playing a game that uses a 3d gfx engine after you've had the phone for a couple months. Reply

    I assume still no update to the device or firmware to get rid of the rediculous neon green push? I took mine back as I couldnt stand the colors on the RAZR. I doubt they have any plans to change, though. Reply

    They seem to have taken an existing device, improved it dramatically with no real drawback, and addressed one of the major flaws with 4G Android phones.

    Great job Motorola.

    I've went through 4 batteries and 2 handsets on the Rezound, and *never* got that battery life.
    4-5 hours with 1-2 hours of screen time on LTE was a MAX.... it would eek out 12 hours of standby time with no data sync (LTE on, why have the phone if LTE wasn't running?) ... and my LTE signal strength was often very good... Co-workers with a galaxy nexus sitting next to me, doing the same stuff, would *easily* get twice the battery life.

    Would be interesting to see if you got a hand picked review unit or not...

    "Unsurprisingly we see an almost perfect 1.8x scaling here and get very close to the expected 21 hours of battery life you’d expect." Reply
