Oh yes, and now we get to the real stuff. Benchmarks! Let’s start with the CPU benchmarks to see how the 800 MHz 2nd gen Snapdragon matches up with the older 1 GHz parts. All of them implement the same Scorpion architecture, except that the MSM7230 is manufactured on a 45nm process as opposed to 65nm for the QSD8x50. Simple colour coding scheme going on in the graphs here: red for the G2, green for the 1st generation Snapdragon phones, blue for anything running TI OMAP 3 underhood, gold for the Hummingbird  Galaxy S devices, black for the iPhone 4, and purple for the Marvell PXA930-running BlackBerry Torch. 

SunSpider Javascript Benchmark 0.9

The SunSpider Javascript benchmark is very quick on the G2. While the Froyo Nexus One remains the fastest on most of these benchmarks, the G2 is definitely getting there, probably due to the untouched Android build it’s running. So even with a slower clockspeed, the G2 has a better score on the JS benchmark than the NinjaBlur-equipped Droid 2 and the Sense UI-equipped EVO 4G.

Rightware BrowserMark

Rightware’s BrowserMark puts the G2 right between the Droid 2, the Fascinate, and the iPhone 4, and about 20% slower than the Nexus One. Given the 20% reduction in clock speed, this is pretty understandable.

Linpack

The G2’s Linpack score is about 25% lower than the Nexus One and EVO 4G, but significantly higher than the Droid 2’s score, potentially due to the higher throughput SIMD FP units in Qualcomm's CPU.

Android Neocore Benchmark

But the really interesting benchmarks are the graphics benchmarks. We’ll start with Neocore, which is Qualcomm’s benchmark to show off the capabilities of the Adreno GPU.

The score is quite good, at more than double the Nexus One’s. The benchmark is capped at roughly 60 fps which is why we see no real difference between the Adreno 205 and the PowerVR SGX 540. For a measurable performance difference we turn to our old favorite: Quake 3.

Quake III Arena demo four - Native Resolution

In a neutral gaming benchmark like the Quake III Arena demo, we can really get a feel for how fast Adreno 205 is. And though nothing on the market can touch the SGX 540, the Adreno 205 basically runs rings around the Adreno 200 in the EVO and Nexus One and even outpaces the SGX 530 in the Droid 2 and Droid X. So while the Adreno 205 isn’t world beating, it brings about a huge change by making the the 2nd generation Snapdragon SoC competitive as far as GPU performance goes. Qualcomm no longer comes with a GPU performance tradeoff.

3G Web Browsing Battery Life

The G2 comes with a pretty small battery, a removable 4.81 Wh (1300 mAh) Li-ion affair that can be easily accessed and replaced. The Nexus One came with a 5.18 Wh battery, the Droid 2 had 5.2 Wh capacity on tap, the Droid X had a 5.6 Wh unit, and the EVO used a 5.5 Wh battery. So naturally, with a lower capacity battery, the G2 comes with less battery runtime too. Thus far we’ve only had the time to run the 3G web browsing battery life test, and the G2 is way down at the very bottom of our charts, matching the Palm Pre Plus in battery life (which has a 1150 mAh battery). It’s not too bad, it’s on par with the Nexus One for minutes-per-Wh efficiency, but 3.5 hours of 3G web browsing is still not very good.

WiFi Web Browsing Battery Life

Update: We're adding battery life tests as we go, so here's the WiFi browsing test. Again, it's almost at the bottom, again it's about on par with the Nexus One on an efficiency level. It's a small battery, so when compared to phones that have 10-20% more battery capacity, it does look quite poor. What does seem to be consistent though is that the OMAP 3 phones are more power efficient, even on a per-Wh basis.

But given the 3G speeds the G2 is pulling, maybe we should give it a pass. T-Mobile's HSPA+ network is FAST, even in areas of Seattle that have rather poor signal coverage. On average, I'm pulling around 5.5 Mbps downstream and anywhere between 1 and 1.5 Mbps upstream. Interestingly, this is signifcantly faster than the speeds I saw out of Sprint's WiMAX 4G network on the EVO when I had it in June. While I can't vouch for areas that don't have T-Mobile's HSPA+ network enabled yet, the areas that do should see the G2 fly. It's T-Mobile's first HSPA+ device, so it should be able to utilise the full potential of the faster network.

    Battery Life & Build Quality are pretty mich the two most important issues in a phone for me (For a smartphone, add Usability to the list). So it sounds a bit weird to say the phone has potential and whatnot, if you're afraid the hinges will break and the battery only lasts a bit more than half as long as that of its competition... Reply

    Despite a die shrink and an underclocked CPU, it's still down there with the N1.

    No matter what's causing it - inefficient hardware, poorly coded software protocol stack or lack of throttling and power-saving features, Google and OEMs need to fix this.

    If you think 3.5 - 4 hours of 3G browsing is bad, try doing it on a moving train with the brightness cranked up. You're looking at around 2 hours. Not everyone has access to a power outlet or USB port during the day to top off their phones.

    Also reviewers need to weigh in battery life more. It's hugely important.. How "smart" is a smartphone that switches itself off at 3pm?

    OTOH there are people like me who average 20 min or so of web browsing per day but do a decent amount of text messaging. Word on some forums is that the switching between 1X and EVDO on Verizon phones is a major source of battery drain, but they don't test that at all. Some battery tests are going to be more useful for some people than for others. Also, there are extended batteries for those who need them. Reply

    I believe you omitted the Front Facing Camera for the Samsung Epic 4G on the chart. Reply

    Desire Z (and all the new SENSE htc android phones) has 768mb, not 512 like the G2 Reply

    my feeling is that a backup copy of the original android image (or of another T-Mobile-blessed image) uses some of the 2GB left.
    G2 Rootkit in action, anyone?

    Indeed the G2 battery life is crippled by the poor battery capacity. But the result still surprises me because I feel the battery life on my G2 is much better than N1.

    I do browsing a lot and my N1 sucks on the battery life, which I later figured out might be related to the OLED panel on N1, which burns more power on white and light colors. I don't know what web sites are included in your test, but most websites like to use white background. Check out the browser battery test here http://blog.laptopmag.com/android-battery-test-rev... G2 having a LCD panel definitely is a plus for the browser battery life.

    Also, Vivek, did you have Flash enabled in G2? That may make G2 browser battery life worse than the other non-Flash supported phones. That's why I always disable it on my G2 :)

    I had a cable buy come over and say that their company don't even use speedtest.net anymore because how in accurate is. have you tried the same tests with speakeasy.net?

    I'm kinda in G2 Battery Denial because the G1 the number 1 flaw was the battery lasted before the 9' o clock news was over. after I got the extended battery pack for the g1 that came with a bigger back for it since the battery way so huge, i could actually use the G1 finally!

    too bad I ordered the battery and did it only 2 months ago. I"m really hoping for G2 Battery Solutions out there soon, because how could they mess up on this again? Hopefully there you can install programs on your SD card this time now too. that was another Flaw.

    thanks for your time.
