Linux-Based Phone Lasts 200 Hours on Standby 187

An anonymous reader writes "Motorola is showing off a Linux/Java phone with a claimed battery life of 200 hours on standby, or 200-250 minutes when talking. If those figures prove true, Linux sure is improving quickly on the power management front. That kind of battery life also suggests that the E895 might be the first single-chipset phone ever to run a complex OS, whether Symbian, Windows Mobile, or Linux. Other features are user-upgradable memory, 1.3MP camera, video capture, multimedia slideshows, and more. Hopefully a more U.S.-friendly version will follow, as happened when Mot's Linux-based quad-band A780 came out a year or so after it's tri-band forebear, the A768, shipped in China."

  • Oooh, that's nice, and I accept a plethora of comments to stream past about how we don't need this in a phone, and that a phone is a phone... But don't you just look at this and think "wow... we've come a long way". I know I do.

    A great phone by itself, with the addition of lotsa power, i'm liking it :)

      I remember thinking that my Nokia 5165 was really great at the time, but this is really revolutionary. I mean, just 5 years ago, monochromatic displays and bulky designs were the norm. Even my baseline Sony Ericsson T237 is a massive leap forward. With Linux on the Motorola phones, it really makes you think about where the industry is headed. Now, if you can access X-terminal and run OpenOffice, then I'd see about getting one. How many phones can you go rm-r on? Not many.

      The point is it only needs 1000mAh battery. Sure, if I have four batteries, I have standby time _four_ times as long as you.

      Iff you checked the capacity of your battery and decided that your phone indeed must have lower consumption then the new phone then you have to check whether your phone runs an OS that's in the same category as Linux and _only then_ can you claim it's not impressive.

            Don't think you will be able to get a BASH prompt on this phone. It's a closed phone; customization will be in Java; and yeah there may be a Java ogg player but thats little advantage over most other devices.

            Linux is "interesting" here, but not "friendly".

            Also, note that the phone is upgradable to 10MB -ooohh! Woww!!! 10MB!!; I wonder why they bother to release such a device, some of their early models had 96MB which is something but low for a multimedia device.

              While I agree with your fundamental point, I'm a software engineer at Mot, and you can get a BASH prompt on the thing - you can also telnet and ssh into it. Granted, this isn't available to the average customer, its still cool. In addition many of the system services are run with SysV style init script. I don't know that anyone's actually done it, but there is speculation that we could make the phone software run on a regular PC, if we did a little emulation of a few hardware components. This is very useful for testing and debugging.

              I actually think that having a 'real' OS on the phone is a big step. If you could see the code for the current OS used on most Motorola phones today, you would appreciate what a step forward going to Linux really is.
              • Cool.

                I was a software engineer at Orange, mostly doing MS Smartphone customisations, and swiftly got depressed when I learned it was a closed Java phone.

                The 10MB is a poor limit though? However getting a bash prompt is what I want, and maybe installing squeak (scheme) or ficl (forth).

The point is that if the OS is Linux, Windows or Symbian, then I can probably get an email program that can do those things and copy it to the phone and run it on the phone. So the fact that it runs a proper OS does matter to some. Yes, I agree the fact that it's Linux is not that important.

    This isn't the first linux phone Motorola has released, and I've previously tried to get a hold of one of those babies, but it seems they are only available in Asia.

    Again, TFA says:
    The E895 is expected to be initially introduced in the Asia-Pacific region in Q4 of 2005.

    Does anyone know why Motorola keeps doing this? Isn't there a viable market for linux-based mobile phone in Europe or the US for example?
    • At this time, The American market is slowing down. All the tech toys go to the far east as they have a much better economy. Sadly, our economy has been in stall for 5 years and not looking better due to the oil price instabilities.
    • "The E895 is expected to be initially introduced in the Asia-Pacific region"

      AsiaPac simply has a bigger more dynamic mobile market than the USA.

    • The 'Asian market', taken with just China or all together is many many times larger than the US. the US is comparitively tiny. Second largest is the EU, which is also larger than the US. There will be distribution branching, but likely they want to collect revenue and analyse market performance before exploring smaller additional markets and (most of all) language ports.
    • I'd imagine that it would be because of the mobile phone standard. IIRC Asia-pacific mainly uses GSM and to a lesser extent CDMA. Probably Motorola has itself geared towards GSM production or something. But really, I'm just speculating. These things probably arn't as much of issues as they used to be.
      • It's a combination of market size and mobile phone standard. The Asian and European markets for GSM phones are much bigger than the US market (which still is mainly CDMA based). But this still doesn't explain why most Linux based phones aren't available in europe neither. (I'm from Germany and Motorola Germany doesn't list any of the Linux based phones on its web site).

        Bye egghat.

    • Its simply that new phones are better received in Asia, and Europe, then the US. Americans are more reluctant to adopt the new technologies, and more likely to stick with an existing phone.

      In the past Motorola has had trouble shifting phones when the took new tech to the state. Having learnt the lesson they now sell them first in more responsive markets like the other phone companies.

      • You also have to consider that most phones in the U.S. are bought through one of the service providers, and U.S. service providers require extensive testing to work out any problems a phone might cause with their networks.

It would seem so, but my knowledge of this frontier is limited to say the least..

    While power management can be performed by an OS, the majority of power savings can come from efficient hardware design. Being a chip designer, I know that the power consumption of my device is not highly dependent on the OS I am running, but on how many fast switching transistors I put in the device.

    Linux has nothing to do with the power consumption. Good hardware design along with good software (regardless of OS) to switch the device off when not in use is the key to long battery design.

    The real problem is any battery life measurement depends very much on how strong a signal you are getting from the basestation. If you're a long way from the nearest basestation and have a mountain or two in between, you won't get much signal, which makes the phone use up the battery much more quickly during calls and really eats into your available talk time.

    Cellphones with better battery life than Motorola's existed even four years ago. For instance, the Sony Ericsson T65i [virtualibrary.it] was the market leader in 2002 having a standby time of 300 hours and a talk time of 11 hours. In practice, I found that phone never lasted more than 200 hours standby and 6.5 hours talk time even with a brand new battery in an area with good reception close to a basestation. In areas with poor signal strength, standby was ~80 hours and talk time was ~3 hours. I expect Motorola's battery life figures fall off similarly quickly with signal strength.

  • by Anonymous Coward
    Spelling matters.
  • My cellphone from Motorola advertised 250 hours on standby. After the first full charge, it died within 10 hours, on standby. Now, after over 6 months use, it comes very close to lasting half as long as promised, when charged for 3 nights in a row.

    Such inflated specs are about as misleading as hard disk MTBF ratings.
  • Can people owning Motorola A7xx 'linux' phones request to download (at least) the linux kernel [patches and all] running on their phone?

    The GPL does offer the right to anyone using the software (on the phone) to read the code. The distribution and apps from Trolltech (and others) may not be licensed so. Either way there's got to be enough GNU tools used, so the non-average user can try and tweak it the way they like it (voiding warranty of course.)

    If there are such possibilities than calling out "linux

    In other news, the new Linux phone lasted the same as the best Windows phone when the both phones were powered off..

    What a bunch of fucking bullshit!

    >If those figures prove true, Linux sure is improving quickly on the power management front.

    It means Motorola's drivers and other code have improved.
    And so fucking what anyway? Am I supposed to ditch my current phone just because this piece of shit can standby 200 hours?

    While reading the article I came across this quote:

    "Such stellar battery life suggests the E895 might be based on a single-chipset architecture, "

    If I read that correctly it sounds like they don't know if was built on the single chipset or not.

    I appears that the "author" does not have access to anything more than publicity manual. I would think that they could claim that this thing cures cancer, stops wars and ends world hunger...and no one would really know.

    That being said, I would love to see this thing reviewd by someone who has kicked one of these things around for a couple of months. Which brings on my second gripe --

    "Availability

    The E895 is expected to be initially introduced in the Asia-Pacific region in Q4 of 2005."

    I guess it does not really matter, because it will never make it to our shores -- and if it does, it won't be until we have flying cars and they find some way to increase the price and reduce the features. This is about the 10th cool gadget I have seen this month that I will never get to purchase in person, or as the case with cellphones, even if I could purchase -- I would never get to use without moving to Tokyo.

  • now if only it didn't have the fatal flaw of that freaking hinge.
  • This doesn't have anything to do with the power management schemes APM and ACPI that typically accumulate complaints when used with Linux. All this means is that Linux is an efficient general purpose kernel, which we already knew.
  • WTF is a "complex OS"?
