Putting Power in Perspective: Estimated Battery Life of a Moorestown Phone

I wanted to get Moorestown hardware in time for the launch but unfortunately nothing is quite ready yet, so we’ll have to rely on Intel’s data.

As I just mentioned, Intel expects a Moorestown phone to idle at 21 - 23mW. Paired with a 1500mAh battery that’s 10 days of standby time. Intel claims that Snapdragon phones idle at 25mW. If that’s true then Moorestown is competitive.

Audio playback is expected to consume around 120mW of power (for the entire platform, not just the silicon). Intel estimates that’ll get you around 48 hours of continuous music playback. Intel was quick to add that this is better audio playback battery life than anyone else on the market today, although both TI and NVIDIA are promising better battery life than that with their next-generation SoCs (OMAP 4430 and Tegra 2).

Moorestown Battery Life (Figures by Intel)
  Total Phone Power Consumption
Idle 21 - 23 mW
Audio Playback 120 mW
1080p Video Playback 1.1W+
Web Browsing (WiFi) 1.1W
2G Phone Call 550 mW
3G Phone Call 1.2W

Intel’s video playback estimates are lower than the competition, Moorestown is expected to only provide 5 hours of continuous HD video playback compared to 10 hours on an iPhone 3GS. That comes from 1.1W+ platform power consumption during video playback.

Intel estimates that Moorestown based devices will last about 5 hours when browsing the web on WiFi. Talk times are expected in the 4 - 5 hour range over 3G, and 8 - 10 hours on 2G.

If these numbers hold true in shipping Moorestown devices, I’d expect to see anywhere from iPhone to iPhone 3GS levels of battery life. Audio decoding seems good, while other aspects like video playback aren’t so great. Web browsing power consumption really varies based on the test. I measured power consumption on my iPhone 3GS and saw 1.1 - 1.3W while loading the AnandTech front page. That would imply Moorestown platform battery life could be competitive.

As soon as I can get my hands on some actual hardware I plan on verifying all of this data myself. Intel claims that the top 5 handset manufacturers see power consumption in the 750mW - 1.5W range, so Moorestown should find itself right in the middle of all of them.

    Anand, Intel said 3 out of 5, you said one magic device, I think they have one sorted out ... NOKIA is a company needing revolution and this partnership is Nokia's hope for smart phone market.

    Also outside US and to some extent Europe Nokia has a very strong foot hold, combined with essentially free software such as MeeGo the road looks good, only IF and a big if, they can deliver on software front.

    “…NOKIA is a company needing revolution and this partnership is Nokia's hope for smart phone market.”

    Only problem: Nokia needs a polished solution fast—its average sales price is imploding and the shareholders are restless. A solution that would require them to throw away all the development work to date would be suicidal.

    If it takes 12-24 months to implement a totally new architecture, with new software (seems a bit optimistic), only a smartphone maker whose roadmap is in great shape today can afford to make the switch; that'd be Apple. But they have just bulked up with PA Semi and Intrinsity; it'd be hard to imagine much Intel Inside.

    Not to mention that Intel's i-series CPUs seem to have been designed to derail Apple's plans of running with a graphics-centric, well-supported CPU. The extra silicon & design time seems to have kept the i3 out of Apple's 13" notebook, while the 15" and 17" have just-a-bit-rocky auto-switch technology to fire up the NVidia GPUs. It doesn't seem that Intel has exactly been courting Apple's product intentions of late.

    Intel First SoC based on Atom is not Moorestown, but CE4100(codename Sodaville) is: http://download.intel.com/design/celect/prodbrf/32...

    Where is the love for Intel's CE product. Anand you should look into reviewing some products based off these products too.

    Sure, is there a shipping product based on the CE3xxxx or CE4xxxx series?

    I remember there seemed to be something like the Yuixxx from Conceptronix or some similarly named Dutch company.. Did they ever ship?

    I am not sure what products have CE products in it... CE devices typically don't advertise this kind of info.

    Lots of rumors when searching for ce4100 on engadget

    Most of those CE4100 results are Intel announcements announcing platform updates or availabilities.

    The TiVo Premier result, I am not sure why it is even there.... TiVo Premier teardown revealed it is fully Boradcom based, IIRC.

    I am very interested to know whether there are any CE4100 products out in the hands of the customers right now... Any Intel employees / PR guys care to offer this information?

    Seeing that GPU part is descendant of Paulsbo... I foresee similar fiasco with opensource drivers as with GMA500. Too bad, it really damages Intel reputation. Reply

    funny gma 600. Even if intel like improves gm drivers 100x fold, they will still suck...So you can pretty much say it depends on that.

    And there go my dreams for useful drivers for my menlow device...it's a PITA. slowing hardware by deliberatley? making horrible drivers.

    Intel's graphics performance as they begin integrating into the CPU improved significantly, to the point of competitive. http://www.anandtech.com/show/2952/2

    Your view point is strictly from a desktop running pixels number as high as 1900x1200 (too much for even the best IGP from nVidia or ATi/AMD), on a smartpone the graphic intensity is not nearly enough... it does not need to win on the highest FPS, it just needs to get 30 FPS or better for a fluid experience.

    The graphics component should be fine, no real reason to suspect otherwise.

    Given the abysmal Linux support of the GMA500 I foresee a complete piece of crap again that will result in this being used in NO android phones. For me Android is the future of the cellphone and frankly what happened with Paulsbro foreshadows the complete crap that this platform will be on Android and other Linux based platforms (like WebOS). The concerns of the OP are completely justified and I had exactly the same reaction when I read the GPU is based on PowerVR like the piece of crap GMA500.

    Intel cannot succeed in the Phone space if Linux is treated with the same disdain they presented with GMA500.
