Battery Life
The OMAP 3430 delivered an interesting mix of battery life conclusions. It's interesting to see how much of the battery savings is implementation, radio chipset, and OS. Thankfully, we have the opportunity to do so here with the N900 and Motorola Droid.
Of course, the Motorola Droid is on Verizon, meaning our call test uses a CDMA 1xRTT '2.5G' network for voice, and '3G'r EV-DO for data. Our N900 came with an AT&T SIM, and unfortunately I don't have any T-Mobile SIMs laying around, so the call test used '2G' GSM voice, and '2.75G' EDGE-GPRS for data. That makes direct comparisons a bit tricky - though in practice it's easy to get a feel for what 3G calling and data on the N900 will be - it will be less than what we measured here for the 2G case.
I was shocked when I saw the call time numbers for the Motorola Droid, and ran the test 2 more times - all with the same outcome. If call time is what's important to you, the choice is a no-brainer. On the other hand, the N900 easily bests the Motorola Droid for WiFi browsing time, though 3G web browsing isn't a good comparison because of the EV-DO versus EDGE difference.
It's clear that battery life is very much an OS stack and radio stack dependent problem, even though we're running the same SoC. Remember that the N900 is running the 3430 at 600 MHz, and the Motorola Droid is running at 550 MHz.

sweet Jesus, that Nokia phone is huge. Does it double as an ice cream sandwich cover?metafor - Sunday, June 13, 2010 - link
Cortex is the CPU designed by ARM. This is available as a hard-macro (layout already done) or soft-macro (just the functional RTL). Some companies license this in either version. For those who license the soft-version, such as TI, nVidia and Broadcom, they can do a customized place-and-route along with clock-tree optimizations and voltage partitioning to try to make the design run faster.However, the micro-architecture is the same.
A few companies have ARM architectural licenses (Apple, Qualcomm, Marvell) and instead of licensing the Cortex line of processors, they design their own. The micro-architecture is developed independent of what ARM did in their Cortex series albeit there will often be similarities.
Scorpion inside Snapdragon was developed in the course of years and while it has many similarities to the A8 from a power-point standpoint, the micro-architecture underneath was designed from the ground up. Everything from the branch predictors, the cache controller, exception handling, execution units and most notably, a partially OoOE scheduler and retirement buffer.
There's also the 128-bit, fully pipelined, partially OoOE SIMD/FP unit.

Well, I find it very strange, that "incidentally" iPhone is never shown in bad light. Could you please update your side to side comparison?Impulses - Wednesday, June 16, 2010 - link
Personally I think there's better things for you guys to do or test with your time... Who cares if a phone's screen colors are more or less accurate, as long as they aren't outright flawed or ugly to look at it shouldn't be a big deal, not like anyone's gonna be doing any pro content editing work on their phones! (I don't even own an AMOLED screen so I'm not particularly biased one way or the other, I own an EVO atm)mojtabaalemi - Saturday, June 19, 2010 - link
I hate the design of nokia mobile phones . in my idea an iphone is far far better !paihuaizhe - Sunday, June 20, 2010 - link

I was just wondering if the author had installed AdBlock+ and then run the browser speed numbers or without it being on. If it was not installed which is what I am guessing from the photos, did you notice an improvement in the render times when it was installed. I actually bought the phone recently after seeing it on sale for 380$ and wanted to know the details. Also, I have heard that the current build of the OS allows potrait mode even for the browser(although it has to be activate through some setting) and not just the phone.drwiremore - Sunday, July 4, 2010 - link
Amanda, delighted to have found you. Given the issues in the title, affecting 20~50% of MOTO Droid users, was surprised to see no mention of it. The MOTO boards are alive with disdain and some feel an in you face attitude by Motorola Droid 2 and X announcements. Would you do an iPhone like analysis of voice, antenna and signal issues across Verizons Droids: HTC incredible and MOTO Droid. Your scientific analysis would be welcomed.
