i really laughed at this one. Sadly there are people who believed a rip-off piece of crap will work.
They make useless things and sell it very expensive and unfortunately some people go and buy them.....

At the absolute most it is a very thin and not very useful heatsink, which *could* reduce the battery temperature a little, however the claims that is reduces electrical interference, somehow converts negative ions etc is nothing short of fiction.
A small section of foil tape stuck to the battery would so pretty much the same thing, and probably wouldn't cost $20 or so :good:
The sort of person who buys this product is also the sort of person who believes their webcam is always watching them and they have fairies living in their garden
so if the idea really works its all because this piece of foil is giving a heatsink effect? how does dispersing heat helps at battery life?

The harder the phone is working, the hotter it all gets, including the battery pack as more current is drawn from it or the charge circuits are trying to draw large amounts of current from the phone charger. This is all monitored by the phone to control the maximum levels, and to throttle back various activities as the temperature rises - hot processors break down internally and overheated batteries can catch fire (especially so Lithium-Polymer and Lithium-Ion types).
This is why your 4X HD gets laggy when playing games etc for long periods of time and why it goes into "slow charge" mode when hot.
I don't recommend putting the phone in a refrigerator to counteract this

So after looking at the teardown and assembly info online, I've started to percolate a notion in my head to double the battery capacity of the NC.
My thinking is that if you sacrifice a bit of structural reliability by cutting out the portion of the plate the battery is on, you could cram another NC battery, scavenged from the ruins of a dead one, into there and wire it in parallel. The end result would be a heavier, probably slightly girthier, NC, with 8000mAh of life. I don't care how bright your screen is or how many rooted roms you're using, that fool will last a looooooong time.
My question is primarily for electrical folks here: any pitfalls to watch out for? Do we know if there's any circuits in the battery itself that might interfere or is the battery unit just a collection of Li-Ion packs?
Of course if you think I'm a mad scientist who must be stopped at all costs, please feel free to chime in too. Just stand over there on the scorched X on the floor next to the death ray...
Hmmm if the kernel allows for a charge higher than the one its in now. Like the evo charging issue with extended battery

Like he said: Whaa? I had an EVO [fun] but couldn't stand the less than less-than-stellar battery life. I'm talking dead by 4pm crap. Bought an extended battery and noticed no improvement. Is that why? Finally downgraded to an EVO shi[f]t [less fun] but I'm not getting the kind of improvement I would've expected going from a 4.6 to 3.6 inch screen, after all aren't they the biggest battery sucks?
sounds too scary for me!!! I think I'd rather just replace the battery (if it is possible to purchase one...)
The main issues would be....
1. extra strain on the charging circuit.
2. the possibility of battery imbalance...leading to extra strain on charging circuits...possible overheat...boom
3. possibility of overheating due to combined heat from 2 batteries during heavy charging...boom.
make sure all of those are taken care of and you are golden. Personally, I would source a larger amperage battery with similar dimensions and wire it in.
I like the idea, carry on

I have one of those, and yes it will charge the Nook Color on the go.
Just a little heads up on the topic, android stores battery info in the boot partition I believe and that's what tells the kernal the status of the battery, I.e. a double capacity battery would report as fully charged when only half charged if you didn't Pachelhoffer the is/kernal and such to match the new capacity.
Correct me if I'm wrong!

These are excellent points. I would avoid hacking the internal circuitry and instead get a hold of an external battery, design a circuit to drop the voltage to 5v and use the usb cable to charge up the battery. Trying to charge two batteries in parallel is asking for trouble because of the imbalance problem.

For the price, I got the XP1000 I think (its in my backpack which I left at work) I actually got it for my Epic to charge when I was out and about and moved around too much to use a wall charger. Works on the Nook too, but I haven't tried a real charge to see how much I get out of it. I would guess if I can charge my Epic 2-3 times that I could at least recharge the Nook once completely.
Warning - be careful screwing around with the internal LIPO battery and circuits. If something damages the single cell battery or voltage gets to low, and you try to add voltage and amps to it, it might puff up and if it does its flammable!
Its a single cell LIPO pack like used in rc airplanes and cars! They are very finicky to say the least when it comes to discharging and charging. Let alone if you want to hook up another one to it and do it wrongly! People have burnt down there whole house at night just over charging one and not babysitting the charging progress!
It is a lithium-polymer battery and not a lithium-ion!
They can catch fire when they puff instantly, many videos on youtube!
Correct me if im wrong, but the battery has a built in monitor and charge stopper so if you were to charge both the batterys via the micro usb slot you would need some sort of trickle charge/sbc kernel mod to overcome this which could be a real pain in the arse and not to mention dangerous considering trickle charge has been known to damage batteries on occasion and we do not have an easily replaceable battery.
I have this unit, http://www.amazon.com/gp/product/B0038VQET4. It will completely charge the battery of the nook.

And a lot of other things, I'd gather, judging by the number of "tips" it comes with.
Do you have any idea if it will charge an NC more than once?
Has anybody thought of any cooling solutions for this phone?
The things get stupidly hot when charging and i have read somewhere this can reduce charging performance?
Personally i am thinking about modding a case.

Put your phone inside liquid and it will be LG Optimus 2x Liquid cooling system!!! Haha, JKJK!!!
How i cool my phone is the same theory as liquid cooling system. Just that the liquid(tap water) is outside.
Step one: take a NEW zip-lock bag(You don't want a swimming phone...)
step two: Fill it full of water, as full as possible.
Step three: Place your phone on top of the bag of water.
It worked for me. Cheers

There are 2 ways that we can achieve this without looking too silly like lugging a liquid cooling system attached to the phone.
1) Fabricate a aluminum or copper backplate to replace the current one that is plastic.
2) Get a silicon case, remove the LG backplate, and slip a piece of copper cut into the shape of the backplate, to replace it, with the silicon case hold on to it. This is what I am planning to do, now just trying to find a shop that do the metal piece for me.
...or just always carry a freezer bag full with ice and when it gets hot just put the phone inside for few minutes
(just to clarify, my unit never got extra hot, not even after playing some hd games for 1h nor while charging)
??? Am I the only one that has no problem with the phone getting hot?... Neither during use or charging overnight...
No you're not, this does seem like a bit of an over-reaction to me.
What a stupid thread, never had any issues with my phone getting hot when charging over night.
Only time it gets hot is when i am using it as a wireless hotspot and its also charging.

Agree 100%. Those who are having those issues should replace their phones as it not seem normal otherwise LG should attach noctua coolers to each phone
I have noticed that with my phone in my silicone cover it seems my phone seems to heat up and at times overheat. As a mechanical engineer it theoretically makes sense. Looking for a sanity check.

water cool it.
All you need is:

2) your htc incredible

step two: Remove phone
step three: Phone is now cooler then before
step four: Profit

it's the battery heating up from use, it's normal. if you are using the 1300 mAh that shipped with the phone then yeah, it does that.
all lithium-ion batteries get warm after a period of use, why the hell do you think they have a "flammable" warning on them? however, if your battery does get to hot, your phone will shut off, almost all circuits are wired with a fail safe break that if overloaded will cut connection to avoid the battery frying the phone. sort of like how your breaker box works in your house.
Agreed. I have a aftermarket 2700 mAH with a silicone cover and I only notice it heating up with use. During use I have seen temp with the Batt monitor @ 106° and just charging 88°
no silicone here and zero heat.

I used my phone without silicone and it still heated up, I noticed it less with the silicone case on.
Either way it's nothing at all to worry about, like another poster said it will shut off if it ever got considerably hot. Happens under constant or heavy usage.
I bought a larger capacity battery but with the same dimensions as the original. I would like to know if the capacity stated on the battery is actually 4200 mah. Have any of you guys any experience of these 4200 mah gold coloured battery?
Sent from my GT-N7100 using Tapatalk 2
It isn't.
On most of them you can peel off the label and it'll say its actual capacity underneath it.
I peeled of the gold cover and it was all silver underneath but no text or data. I tried battery monitor widget. No help it reports I have 45 percent left when Android tells me 1 percent left. No battery power left the phone turns on. Then put on recharge and the app tells me 25 percent left but I just put on charge from 1 percent. Definitely feels worse battery life than original.
Is there a larger battery capacity than the original but with same dimensions?

Most likely there isn't..
You can check the N7000 forums, there has been large and thorough research about these "illusive" gold batteries.
I will sum up it to: Gold batteries are most of the time only 60% capasity of OEM batteries. You can check this by using a fysical current meter and compare the currents. Another way to compare is the weight of the batteries
Will try what you suggested.
Sent from my GT-N7100 using Tapatalk 2
I had that battery and tested it using external battery tester. I can't find a thread where I posted about it, but I can tell you it was 2000 mAh, not 4200 mAh. Physically you can't fit a large cell into OEM footprint. Samsung is very good in feeling up maximum capacity per size. So the best you can get with any standard size battery is 3100-3200 mAh. HK brands use unreliable cells and capacity is even lower.
I'm attaching pictures of my setup and final measurement.
Hi Vectron. That looks like the battery I have. I tried it for 1 week. Not great and today switched to original. The original does last longer.

Not sure, maybe the breakthrough lies in the idea.. we might be better off using stuff that recharges the battery during normal use in some kind of way. I'll leave that to the producers to figure out
I don't understand why people buy these cheap @SS batteries
Basically you can purchase a Qcell 6200 for $20 and it lasts 2 days and it's fairly slim - Heck, i'm running a stock battery bumper case that fits 100% perfect

Actually, a few university programs have made recent leaps, however we're probably looking at a few years before seeing them in production.
The new LG Optimus G Pro has a slightly larger battery than the stock Note 2 but only by 40 mah..the LG Pro is the new 5'5 in. Note 2 contender.
Not sure if it fits our Note 2 though ..when I was gonna buy a spare battery I was looking into the LG one but no one sold it.

4800 maH with Stand. I placed an order but yet to pick it up due to low stock. I see other powerful batteries but they add that bulk and this has the stand which I absolutely need
Any opinion
This would add the most bulk to me, it makes the phone another inch longer. Plus that's not really the mah you'll get out of it since it's not replacing the battery just charging already in there.

tx for the reply, so this is not really a battery? all it does it charge the one I have i.e, I got sit there waiting for it to charge
I assume it takes over when the internal dies off?
PS Would you recommend the best extended battery? with case/stand, I keep hearing mugen - any other one?
Yes it just charges the internal battery you have. You can turn it off and on when you please not just when its dying although its ideal to use it when your phone is low on power. As for good battery with stand I would recommend either Mugen or Seidio. Amazon seems to have the battery and case with stand for mugen together but with Seidio looks like you have to purchase the battery and case with stand seperate. Both up there in price but very good. Hope this helps.
