N1 Safe?

I know it's got the SAR rating as within acceptable limits and whatnot. But this is the first phone that I can actually feel the heat radiating off where the antenna is. Especially after a bootup where it's looking for the network. Gives me an uneasy feeling.

Where's the antenna? I know many phones have the antenna down by the mouth piece which seemingly is safer.
 
I believe it's down the side. Can't remember where I saw this but whichever site it was has taken the phone apart. Maybe someone can confirm?

Can you really feel the radiation..? Or is it working temperature heat? I'd be surprised if you could. Maybe it leaves a metallic taste in your mouth...
 
According to the documentation it's on the bottom of the phone on the backside. Has a picture telling you not to place your fingers over that area and some blurb about exposure. Really scary that you can feel warmth radiating off that area when there's antenna activity.

You may be just feeling the heat from the battery. A lot of "smartphones" give off heat when thay are used a lot.

Nope...battery is in the middle of the phone. This is coming from the lower section and it's pretty focused right where the antenna is.

Sorry to break it to you, but that heat feeling is entirely your imagination.

I wouldn't worry to much the SAR rating is fairly low when compared to other similar phones;

Nexus One
SAR = 0.37 (Head) and 0.74 (Body)

G1
SAR = 0.69 (Head) and 1.11 (Body)

I'm sure there will be more accurate figures elsewhere.

I saw those numbers before I bought mine as well, and thought they were pretty good...but the owners manual has them published as much higher (see page 26):

0.867 w/kg Head @ 1g
1.39 w/kg Body @ 1g

0.823 w/kg Head @ 10g
1.53 w/kg Body @ 10g

1.6 w/kg is the USA legal limit...so unfortunately this thing runs pretty high on the SAR scale.
 
Are you gettiing the "heat" when plugged in and charging ?

Are you getting the "heat" while on voice call ?

Are you gettiing the "heat" while using phone for long period at a time ?

Are you gettiing the "heat" when the phone is sleeping while sitting on the table ?

Are you gettiing the "heat" in any other way besides at start up ???????
 
Noticed it the most during startup. But now that i've played with it a bit more it very well could be battery heat radiating downward. The reason I say this is that it's warming in that exact spot now that i'm charging it again. It would make since that booting puts an instant strain on a battery and would cause a rapid heat buildup.
 
My BlackJack II gets very warm, quite quickly as well when it is in use, but it is from the battery, which I think is the same as with the N1...
 
There are more sources of heat in a phone than just the battery.... That little thing called a Snapdragon maybe?
 
According to this teardown of the phone: Nexus One Teardown - Page 2 - iFixit

Looks like this is exactly the area where lots of instant heatup items are:

Snapdragon
GSM Power Amplifier
Power Management Chip

All sorts of stuff that would heat up and it's all packed down there. So problem solved and I can now happily use my N1 without fear of baking. :)

Thanks for the info ChrisFix, thats a fairly large jump from the earlier figures.

What is the difference in measurement? I usually only see one pair of head/body measurements on most sites.
