Scots_boyuk:
I don't remember the name of the effect you are referring to, but it has to do with an electron beeing in two different places at once (it travels through both sheets of metal simultaneously) so it hasn't got much to do with this case.
edX:
In order to dissolve this "resedue", the battery extender would have to do "work", and thus require energy (you know, you always have to put something in to get something out). Since the battery extender has no source of energy, I don't see how it could possibly work.
I'll admit, I am no expert on this, and probably don't know any more then the next guy, but in my opinion for this battery extender to work, it would have to contradict the basic laws of physics. Ofcourse everyone else is entitled to their own opinions, so I will just leave it at that.

No no I totally agree with you Wrath, all I was saying is that in theory there is a possibility of it working in a certain way. The only problem is, such things are very much in the realms of super science and I very much doubt they are being used here, if it was that effect (the name of which also escapes me too!) then surely there would have been a lot more applications of it, if someone had found a way to implement it practically.
The battery extender probably works on a far more mundane principle. As someone has already pointed out though, nobody who has bought it has anything bad to say about it. Perhaps I should just bite the bullet and go for one myself?

what about the simplest theory, that it repells the heat coming from the phone from effecting the battery?
A battery in a hot environment has a significantly lower efficiency.
I believe all this sheet actually does is prevents the heat from the phone from reducing the battery's normal efficiency...

Possibly, though I'm not sure if heat going into a battery is a bad thing, I suppose too much would be, but isn't there millions of pounds spent each year in attempts to keep heat from escaping from batteries?
Maybe the battery extender traps the heat?

I have the Martin Fields version of this battery extender and I have been running my own tests or at least as best as I can. I also used a SPV to test against.
On the SPV, it seemed that it did nothing, in fact it seemed to have reduced the battery life, and we checked this twice with the same result. On average about 10 hours less.
On the P800, my tests are not yet complete as I run them twice (both with and without). I have been writting down when and how long I use the phone with what apps both with and without the extender. I fully discharge the phone, fully charge it and go from there.
I will post my findings when I have finished. All I can say at the moment is this....
The apps seem to run faster then they did before the extender went in. Access is better overall. A bonus of the improved flow of ions?? Perhaps. Don't know. Also it does seem to last a bit longer. Very odd when you look at the SPV result (although it was an SPV and crap anyway ...
).
I am also going to try it on my vid cam batteries and a T68m.

This thing COULD work, to a degree anyhoo.
Think thermal effeciency! The hotter the battery gets the less effecient it is, ie the sooner it will run flat! So if this little metal dubrey helps dissapate heat then it will increase thermal efficiency and thus on a phone which is used heavily then it might increase the operating time!
Just a thought though mind, as i've not bought one myself. I'm just basing it on the warmth the P800 generates if you say play Monkey Island for 2 hours! *and thats with it sitting on a table with my hunched over it, not even holding the unit*

Couldn't it also be doing the reverse? Instead of dissipating heat, could it in some way be capturing the thermal radiation given off and recycling it? Thus providing the battery with energy, which it would otherwise have lost to heat dissipation.
Just an idea, though it would be interesting to find out its effect on other devices.

Erm, no!
There are ways of scavenging energy from heat, and people are working on chips that do just that. But this isn't one of those! You'd need to at least have some connections to the terminals of the battery, to put the power back in.
Removing heat from a battery could increase its life, as the internal resistance of the cell goes up with temperature and the higher the internal resistance, the more energy is lost. However, to have any effect the overlay would need to be a decent heatsink. Also, the effect would only be noticable during high current drain periods.
