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. |

Since we are on the subject of inovative sollutions, here is a link to the TCP/IP Pipe Scrubber, which will improve your internet connection speed by "magnetically balancing the line." Enjoy!
P.S
Due to the difficulties of relaying sarcasm in a written post here we go.... **sarcasm**

Although basic physics does indeed say that energy cannot come from 'nowhere' this very scenario can actually happen. It has been demonstrated on a number of occassions and requires no more than two highly polished metal sheets. As yet there is no satisfactory explanation of this effect.

You are referring to the Cassamir Effect and it is well understood and has nothing to do with this.
The Cassimir Effect occurs when two very flat plates are held very close together in a vacuum. Despite what you may think, a vacuum is not empty. Quantum Mechanics tells us that virtual particles are constantly popping in to existance before disappearing again a tiny fraction of a second later. Quantum Mechanics also tells us that particles can also be considered as waves, and so each has a "De Broglie" wavelength. If the plates are held together with a spacing smaller than the De Broglie wavelength of the particles in the "vacuum soup" then no virtual particles can exist in that space. As a result, between the plates is a true vacuum, while outside there are particles hitting the sides of the plates.
The result of this is there is a positive pressure on the outside of the plates which exerts a force that pushes the plates together. While many people have fantasised about turning this in to a source of free energy, you can't. The energy required to pull the plates apart so that the cycle could repeat would be greater than the energy gain in the first place. No free lunch! |

Fair enough, as I said before my speciality was Astrophysics, not electrical engineering. I am pretty sound with theoretical physics, but not so hot on applied physics. Cheers for the info.
Has anyone asked the manufacturer how they claim it works?

Well, I am not an Astrophysicist, have very little knowledge of physics, electrical engineering or applied or theoretical whatever...what I seem to know much more about than any of you here is practical usage of the battery extender.
My P800 was last charged full on Sunday afternoon and has not been turned off. I am now at 57% and have made at least an hour of calls today, surfed for 30-35 minutes, and all the other bits and pieces without including all my usage on Sunday and monday. I reckon this extender whatever it is made of is giving me at least another full day of use...well worth it in my opinion. You can argue all you like and call it BS or whatever...I took the plunge, bought one even though it seemed unlikely to work...well, to my suprise it has worked and I have no idea why and I really don't give a damn! 
The best way to win this discussion is to at least have experience of the product in question! |

I am aware that a vacuum isn't entirely empty, but I didn't want to go into too much detail to avoid numbing people who don't understand the principles behind it. I am in agreement with you that it is totally impractical, I was merely pointing it out in reference to another post that energy can't come from 'nowhere'.
The Casimir effect isn't the only instance of energy appearing from 'nowhere', depending on the model you are using there are theories to allow for it, but I won't go into them here because;
a:) they have bugger all to do with anyone or anything
b:) I highly doubt they are being employed in this product
c:) I can't be arsed!
Maybe the battery extender absorbs farts and converts it into extra energy? Anyone with good reports on it been farting a lot lately?:P
Cheers
