Using mobile phone as an internet radio

    Not being able to find a small internet radio to buy we liked, we got mobile
    phone with which we link with wi-fi to a modem router, and use it as an
    internet radio.

    Keeping the phoned plugged into its charger all the time, we are using it to
    play *all-day* background classical music through an amplifier and speakers.

    Since the phone has no 'moving parts' unlike a computer, we are wondering if
    this continuous playing all day of the phone is going to shorten its working
    life ?

    Using anything shortens it's working life.
     
  3. Not so. There aren't any obvious failure mechanisms in solid-state devices
    (other than dopant migration in high-power output transistors).

    It's also true that most mechanical devices "like" moderate use. Letting
    anything mechanical "sit" most of the time will probably cause it fail
    sooner than if receives regular use.

    It's now possible to build computers without moving parts (other than the
    optical drives). My new computer has a solid-state "hard disk", and you
    wouldn't believe how fast it boots up, or how fast programs start to run.

    There are many factors that cause something to fail. I you don't use it,
    it has no working life. I don't wish to play semantics but if you use it
    you are using up it's working life.
     
  5. There are many factors that cause something to fail. I you
    Not so. With mechanical devices, regular moderate use provides a longer
    useful lifetime than using the device only rarely.
     
  6. These, if flash memory, do have a definite wear out mechanism, although
    they do try to avoid writing to the same spot, even if the software
    does, to mitigate this.

    I don't agree but will say no more.

    The battery may not like being plugged in forever.

    How much did you pay for the phone? Would it bother you greatly if it is stolen or if the battery fails to hold a charge, did you get it fairly cheap, did you buy a new mobile phone for regular use and this is an old phone from a previous cellular plan, etc.?

    I used to use an old cell phone (well, it was "old" in the sense that I changed cell phone carriers) to play music from the internal microSD card for my plants in my office (a Mythbusters episode showed that plants like music), until the repetition of the songs drove *me* crazy. =)

    Not sure if my News server supports x-posts to the entire Usenet, but
    I digress.

    An incandescent light bulb is a good example, If it lasts 1000 hours
    when run continuously, its life will be considerably shorter if run
    (say) 4 hours a day and the time it is on added up.
    Equipment with lots of thermionic devices like very early computers
    were, as far as practical, never switched off because of the
    likelihood of failure.

    I believe turning the bulbs on and off can induce thermal shock which causes
    premature failure.

    http://en.wikipedia.org/wiki/Thermal_shock

    See also: http://en.wikipedia.org/wiki/Thermionic_valves

    "The common wisdom was that valves—which, like light bulbs, contained a hot
    glowing filament—could never be used satisfactorily in large numbers, for
    they were unreliable, and in a large installation too many would fail in too
    short a time".[13] Tommy Flowers, who later designed Colossus, "discovered
    that, so long as valves were switched on and left on, they could operate
    reliably for very long periods, especially if their 'heaters' were run on a
    reduced current".
     
  13. Correct. SSDs are an exception. They contain "leveling" software that makes
    sure the disk is written to evenly. The Crucial disk I use is spec'd at
    about 40TB of total writes.

    ** Bollocks it does.

    There are many applications where incandescent lamps are turned on and off
    constantly and their life span is the same.

    The OP's hypothetical example ( don't ya just LOVE them) is typical of
    domestic lamp use.

    Fuckwit.

    No Phil, that is not correct. If he only listens to Rap , its lifespan will
    be shortend greatly.

    He is right, the stresses involved in the turn-on of the bulb each
    time is equal to several hours of continuous running. If you cycle a
    bulb on and off every few seconds, the total on time before the bulb
    fails will be only a few hundered hours for a 1000 hour rated bulb,

    Seems to go against the whole ethos of exercising. Never get out of bed and
    live forever ...

    You'll have dropped it well before it wears out :). BTW, a cheap PC
    speaker set might be handy if you want a little more volume. And you can
    probably find a decent streaming client if you have your music sitting on a
    PC somewhere.

    Just like not using it does in fact.

  20. It would be a strange way to rate the life of a lamp - on constantly,
    since this pretty well never happens.

    Do you find the 'flasher' lamps on your car failing more quickly than
    similar lamps which don't flash?
