Battery Heat fix test

[twolastnames]

So a kind of nutty dude on another place within the Internets stuck a piece of paper under his battery to help shield it from the heat of all the heat producing craziness inside the phone. He was reporting quite a difference in physical feel, and also actual temps of the battery. So I tried it as well at work, and what do you know, so far it seems legit. It's so amazingly simple, that of course it probably will work.

So my phone normally does not get crazy hot like some dudes, but when I'm charging and playing a game\cruising 4g, I'll stay around 40C-43C (104F-110F). Maybe I'll crack 45C. Put a stupid piece of paper under the entire battery, and a bit around the sides, so far have not cracked 37C. Granted, the hardest I pushed it was watching HD YouTube vids for about 10 minutes while charging, but it seems promising. Before, also just while charging the phone, it seemed to get a bit warm, now after a charge from 25%, I'm cool as hell.

I'm not sure why it works so good. Usually I can feel even the screen getting warm, but not so. Phone is staying cool. So I wonder if heat from the processor gets into the battery, and then the battery starts to heat itself up, and in turn, heats the processor up? Just my guess.

So, who wants to try and report back? Would be interested in the guys who normally get close to 120F regularly, just to see if I'm as batty as the dude on the other place.

my phone just started overheating yesterday while charging it using 4g and/or playing angry birds space. 120 degrees F.

i meant to swap to my spare extended battery and see if that helped but forgot when i went to bed.

so today i'm talking to my pops on speakerphone, have the phone on 4g tethered to my pc browsing the web at the same time. doesn't even break 95. then played angry birds space while charging, on 4g. cool as hell.

weird.

i have seen 130?F on mine. this would be interesting.

If the phone is cooler on the outside, with the same processing load, then it seems like it must be trapping more heat inside, possibly cooking the little chips that make it go.

This! Just because you no longer feel the heat does not mean it is no longer there.

Thankfully there are few places in the phone that can trap heat. If this is a fear. Try the "fix" and try to force your phone to get hot. Turn it off, take it apart and feel the pieces(battery, battery hole, LCD, SIM, SD). See if they're hot, that should tell you if something is holding heat. I think the paper trick is keeping the LCD from heating the batt and vice versa.

Personally I'd fear fire more than anything with this "fix"

I happen to agree. Heat is inevitable and the more your phone has going on the hotter it gets. If you have a case it will run hotter. If toy keep it in your pocket more heat. Using a car charger over an ac charger more heat.

Adding stuff to the phone in way of paper and such is to big of a risk for fire imo.

^someone typed that response from their phone

Has anybody's phone been north of 400 degrees? If no, what is going to catch fire? I did play a game that will get my phone around 45?C last night, and I topped out at 41?C, so about 10% less heat. I'll keep a fire extinguisher close in case I start on fire.

This works because:
A. The spacer is blocking the hardware heat from escaping threw the battery and keeping it in.

B. Because the spacer is blocking one exit and making the heat go to another one with increased flow.

A is more likely than B unless the phone is now getting warm somewhere it did not before like the screen. It could now be spreading it out so thin that the temp change is unnoticeable, but I think that is a little much to hope for.

It could be like the cardboard trick on the original 360's, but that was an issue with air flow from fans that we don't have.

The temperature that paper needs to ignite is part of the issue. The other part is that paper is not made to be a heat shield.

A lithium battery is not supposed to be a heat shield either. And a case could be made what is more dangerous at 140?, paper or the battery? Seeing that 150? makes the battery go boom and paper has up to 400?, what's the harm?

So far I think the paper helps for somewhere between 20 and 30 minutes. After that it seems to maybe just partially help. I'm on the side that says it's keeping the guts of the phone and the battery from heating each other up.

I'm sure ground up puppy paste would work better, but I used all mine smoothing out my rough knee skin! Anybody got any better ideas? A passive head sink would rule, but the home made one I saw on a og DROID was crazy.

How about some tin foil that protrudes out one (or both) side(s)?
