Your Cellphone Might Have An EDL Capacitor Acting As A 2nd Battery

This is one of those “The more you
know” moments:

There’s this new story about how Even
Powering Down A Cell Phone Can’t Keep The NSA From Tracking Its Location.
And spyware got installed by your phone lying to you about an “important
woo-woo update v4.0.2934″ and you could care less about what the update
does. Well you’re going to want to care, sunshine!
Why are you constantly updating a phone that has no direct problems for YOU
personally? Back in the old floppy disk days, you could feel free to use
MS-DOS 1.0 for the next 600 years for all we care. But phone vendors wave
their magic icon and have you “trained” to go swipe/swipe,
swoop/swoop to update things. Please stop all that updating.

Cellphones are starting to use what are called
EDL supercapacitors. They hold a charge like a battery, and probably have
70000 μF (or 70000 MFD) of capacitance. MFD stands for microfarads.
Gold
Electric Double Layer Capacitors

Typically you’ll see listings for C-EDLs for
sale (CAPACITOR FOR MOBILE PHONE) as in this Zauba.com link.

Now some people noticed the C-EDL on the
mainboard in their phone leaked.
Which means, the phone can’t keep the right time. And people in forums
complained of resistors near the C-EDL getting fried. Like here:

So the people with the fried-EDLs said:
“Can’t we just pop that EDL out of there and have the phone still
work”? Now the average Joe/Jane is thinking: ARE YOU NUTS? You’re
kidding me, right? Get into the board, and void your warranty? You bet your
fanny. As it turns out, you can remove the C-EDL and have your cellphone
still work. Who cares if the time is right? So maybe you can’t play Fruit
Ninja correctly.

In other worlds, Blackberry mainboards have a
tiny second CMOS battery like desktops do. More daring cellphone DIYers:

resort fix for dead bold (no red led) – BlackBerry Forums at CrackBerry.com

When you see photos of cell phone mainboards,
look for the C-EDL. It’s round and typically has an tiny overhead metal clip.

So none of this news is NEW to people who want
to stay hidden. See why C-EDLs are NEVER mentioned on TV shows? The
“throwaway” concept is mentioned in shows left and right, but NEVER
the dirty secret of leaking C-EDLs.

In the future the Eye of Sauron agency will
have very limited ability to find the actual people they’re after (using cell
technology anyway).
