You were right the first time Stigy :) its called speed binning. 4430 and 4460 are from the same wafer.

I read that as: "right FOR the first time Stigy" and was in the midst of typing something sarcastic back to you until I read it again.

That's good to know though -- didn't know they were from the safe wafer though. I'm gonna do some reading on the processors tonight -- seems like some very interesting stuff going on in the mobile space with these processors.

As it's an aramid, it's actually a good heat insulator - it's used in brake shoes, for example.

Hence the reason it isn't a good heat dissipator...it keeps the heat inside whatever is contained within it. So you have Kevlar on the back of the phone, that kevlar is keeping heat from escaping the device through the back. The heat has to go somewhere so twice as much heat is escaping through the screen because it can't escape through the back.

Wrong attitude with American politics.

I don't want anyone voting, unless they understand the issues, understand where the canidate stands, and vote for who they legitimately think will improve things. To many people just go out to vote and don't give a rats behind about the issues.

Popularity contests are for american idol. Electing someone to run the future of this country should be done by intelligent individuals.

Mods: Sorry for the rant, feel free to do what you will with this post. But I did have to say it.

Early, is there anything you don't know? Or do you just Google these things on the fly and then post in order to seem smart to us? :D

I was a weapons scientist for decades - gets you lots of cross-experience on all sorts of arcane things. ;)

Until people see me talk this way in person, it's pretty common to just think I'm like mr. Google. :D

Hey - either way you want to think of me, it's okey dokey by me. ;) :) :)

That is just seriously disturbing, all the way around.

I don't recall AMOLED screens running that hot, and I've said how to expect reasonable coolness based on my dual core.

There were a lot of initial complaints on high heat when the SGS2 came out, people without the problem were starting flame wars on it (no pun intended, implied, or made).

Known top sources of heat in a cellphone, in no order: processor SoC, 4G radio SoC, and battery.

4430 being overclocked + thin phone = less distance between hot stuff and screen, Yeah I am not surprised.
Click to expand...

This is what I was thinking. Having all those components crammed in that close together has to make for a pretty solid heating system. I wonder if the battery not being removable has anything to do with it. We have heard of iPhones catching on fire, right?

Please reconsider.

As I designer, please permit me to re-express that:

The designers fully expected that they'd just built a handset where they were so careless in heat sinking that it was unfriendly to the human hand.

I think someone had better be surprised somewhere, just my opinion.

Um, not really sure what you are trying to say here... Am I not supposed to be unsurprised that when the aspects of the phone are considered together, its really hot? I do understand that you are saying they didn't do this on purpose or by design, but as someone with more experience than I would like in heat dissipation design, when you make internal components run hot, and don't give them the distance and/or mechanisms to cool, its going to be hot. Thats all I'm sayin.

No no - it wasn't a criticism at you.

Taking exactly what you said (either post) - isn't it surprising that some manager somewhere didn't send them back to the drawing board?

Sure, I hope it's firmware or something fixable - but "too hot" is an unacceptable condition for shipping something - therefore my plea - let's all get surprised when anyone does this.

If they think we're not surprised, they might keep it up.

That's my concern.
 
This is probably one of the worst designed phones I've seen in a while. I have a feeling they will have a lot of warranty returns on this one.

Im posting from my droid otherwise i would hook you up with some links but yes gooogle speed binning. Same wafer just stable at 1.5 and 1.2. Im assuming they clocked it down to 1.2 for heat issues. Wafer may only be able to operate at that speed without heat. No idea thats above my pay grade.
 
svt_gEEk said:
Yes. Eventhough they wouldn't admit to sending out an overclocked processor, the 4430 was designed for 1GHz. 1.2 GHz is overclocking that processor series, stable or not. It will produce more heat. But, also, like I said in an earlier post, Kevlar on the back is probably contributing to the heat escaping the device through the screen causing the screen to heat up.
Click to expand...

If it requires stock voltage to maintain 1.2 GHz clock speeds, then it's not getting overclocked. It shouldn't generate any more heat than the 1.0 binned SoCs.

More than likely, you're right about the Kevlar though. That, combined with the thin profile of the phone are what differentiates it from "non-hot" phones.
 
drbugsmn said:
This is what I'm wondering, that there isn't much at all between the SOC and radios and the screen? Plus, what is the thermal conductivity of kevlar? This is something that the engineering effort identified early!

I can tell you from wearing a kevlar vest 5 days a week that it retains heat very well,It does not breathe at all.

Oh, ok I got you now:). Yeah I AM Surprised they would design a phone that is hot, but I am not surprised this design is hot. If you get what I am saying.

I'm sure you meant "without excessive heat", there is no way the processor will not generate heat ;)

Well we do need to wait and see after more reviews come out. The heat complaints are anecdotal at this point. A couple of folks are reporting it, including our intrepid Steven58, but it could be a localized or explainable issue.

Let's face it, we're all SGN fans in here for the most part, but a defective RAZR that has been hyped to hell and back would be bad for the Android ecosystem as a whole.

Yeah, you are right. Just because it doesn't say 1.2 GHz on the spec sheet, doesn't mean they are overclocking it, that statement of mine was not correct. However chances are it will run at the higher end of the heat tolerance. So even if it is speed binned it will most likely run hotter than average, but not outside tolerance.

My intent of "dont care who you vote for" was merely to not drum up political arguments. This isn't a big popularity contest election cycle (around here anyway). Mainly local town/city positions that effect us the most.
