    I have a blackberry pearl 8130 and did a battery pull this evening and noticed a small watch battery on the circuitry under my normal battery and I am wondering what it is for, or if it is simply the cmos battery that keeps the clock inline.

    Thanks

    I think he is referring to hardware in the device, not an icon on the screen.

    This is a Storm, but there is a battery in the picture.

    My buddy with a 8310 reported this to me a couple weeks ago.... He dropped the device and the bottom case opened a bit, he said a small battery fell out.... But yet phone works fine

    CMOS maybe? pull the watch battery out, then the phone battery. leave it out for an hour or 2, reinstall it and boot up. Check all settings/messages/etc to see if anything is changed or missing... other then that I have no clue....

    Perhaps it has to do with RIM's excellent device security?

    I don't know. I see one in my 9000 also. I never gave any thought to what it is for.

    It probably is to keep the clock working.

    But that gets sync'd off the cell towers as soon as the device gets powered up, doesn't it?

    Well if you do a battery pull you don't lose your OS or contacts, so presumably the battery is there to keep the flash storage working. I think the flash they use is more expensive (and faster) than the kind you find in memory cards and it probably needs power.

    Just an observation, when your main battery runs to zero, it shuts off the radio, however it can in an emergency call 911 maybe its a backup in this situation.

    I don't think that size battery could power the radios even for an emergency call, much less boot the phone or keep it alive.

    Flash is a possible use for it, my roommate who has a storm suggested that it might be used to power the Java something on the phone, don't recall what exactly he said since it was late.
