i was wondering about what temp is unsafe for an iphone....sometimes at work i leave it in my car.....and its about 47-50 degrees outside....does anyone think thats too cold for it to be out there for a while?
thanks
brent
 
im not too worried about stealing...its hidden in the car...and i can see it from the window.....i am still concerned about the temp. though.
 
Extreme heat and cold are not good for electronics. That said...

wow those numbers are pretty poor. I mean people do use their phones in freezing weather and in weather that is about 100 degrees.

Now the car factor is 130 degrees or even below Zero.
Either apple really screwed up or they are just playing it really really safe on their numbers. Mind I will say on multiple ones of my electronics I have gone out side of their temperature range

Your right those number are poor. In vegas its over 113 almost every day in july and august. But I bought my iphone on august 4 and had no problems but i would never leave it in the car where the temps can top 130 in the middle of summer.

Those are standard warranty and performance numbers. Flip open any electronics manual you have lying about. It'll be more or less identical. You shouldn't be using unprotected consumer electronics in extreme weather unless you're willing to bear the cost of replacement. That's all the numbers mean.

You should never leave electronics turned on in a hot (or cold) car. My nephew has gone through many a head unit in frigid New Hampshire mornings by turning on the stereo before letting the car warm up in the morning. I toasted a cell phone LCD on a trip to Palm Springs by leaving it in a rental car for three hours at a conference.

It's a basic "use at your own risk" provision in extreme temperatures.

Most of the time I used to see 110 being the high operation and storage being closer to 140.

Reason I say they are pretty pathic is on a very regular bases the southern cities will get 95+ as there high. Put that over pavement and it easily breaking 100 degree. And this is normal summer weather. While leaving it in your car is one thing but not be able to handle 110 is rather said. This summer I had to work outside the high was 107 for the day. Pavement was measured at 130. That more than likely meant I was working in an area with an air temp of some where over 110. While this is an e xterm. 95 max operating is sad for a cell phone. If the temperature gets 92-93 degree outside (very common) that means those cell phones will regularly being in over 95 degree heat because of the urban environment and being over blask asphalt will push it about 95.
Now leaving electronic in ones car over the summer is do so at your own risk. There are places in a car that the temperature will get over 190+ degrees the over all temperature in the car can easily climb up to 140+. Heck the dash board will get hot enough in the summer to bake cookies.

It is more the numbers can not even handle t he normal weather much less exstreams .

I would like to see a product with this operating range. 35C is the upper end for operating environments on almost everything, with a 45C/-10C ceiling/floor for exposure.

No, it's not "normal" weather, and it's not an environment in which most people spend a lot of their time. It's also not a magical breaking point. Walking outside is not going to break your phone, nor is keeping it on your person if you're, say, a construction worker.

It has nothing to do with what the device is "able to handle." It is a fixed parameter for operation. A device will work outside of that range just fine, but you do it at your own risk. Motorola products come with the warning never to expose the device to temperatures above 45C (the magic 113 degrees), just like the iPhone. Why 45C? Because that's the specified liability limit for batteries used in small electrics more or less across the board. You're not likely to come across a consumer battery with an approved range above 113, and certainly not 140 as you suggest.

I'm sorry, but 100 degrees is not a normal operating environment for anything. Take your desktop, TV, or microwave and bring it outside and see how long it lasts in such weather. The safe money is on that desktop overheating and shutting down long before your phone will. You should generally be starting with a room temperature device, and so unless you spend hours outside on an unusually hot or cold day with your phone, you're fine.
 
32F operating temperature..at that point you shouldnt care much. iphone doesnt work well with gloves anyway. brrrr on the hands.
 
i was just curious...i work p/t at an ice rink and lately its been warmer outside 40s and 50s than in the rink 30s....so i guess its better in the car....i was just afraid of bringing it into the rink because i work near a skate sharpener and i was concerned that the dust from that machine would scratch up the screen

What? Darned Californians <grin>. Yes, of course over 95 is normal summer weather in the Southeast. And Southwest, for that matter. And yeah, some people spend a lot time outdoors working or playing in it.

I think you're right that the battery is the major limiting factor.

"Over 95" almost nowhere happens more than 30 days out of the year, and only for a few hours on those days. The average daily high doesn't breach 95 in the overwhelming majority of the country at all. People have a tendency to exaggerate.

Even on days where the high is above 95, the actual amount of time that a given location will be over 95 degrees is at most a fraction of the day. All together, even in the Southwest, there's maybe an equivalent of one week out of the year where the temperature is actually above 95.

I would hardly call 1/52nd of the year "normal" operating conditions. Even in Summer, temperatures that hot clearly occupy a small minority of the day. It certainly gets hot and stays hot, but the idea that people actually spend a meaningful portion of their year in 95+ heat is a fantasy.
 
it IS normal

I live in Greece and it IS "normal" in July-August to have 36c - 42c and higher some times. I have a iPhone 3G that still works.

Please stop saying "is not normal" it IS normal

It's 102f on where I am sitting and my MacBook Pro is working fine at 125 to 145f and a fan speed of 1657rpm my iPhone is fine using the ipod app.

this is a normal operating environment for Greece in July.

While this is all true, it should also be noted that air temperatures reported by weather stations are taken in the shade. In the sun, it can get a LOT hotter than that. When it is in the 90s, it can easily be 120 or hotter under the sun.

That's why my phone goes into emergency mode where it can't be used if I'm out by the pool in the summer and I don't have my phone covered by a towel or sitting in the shade.
 
an insult

"almost nowhere" well I live in Greece and the daytime temp june-august is 32c/89.6f to 46c/114.8f that's 93 days with temp close to 95f. So by your def of ".....almost nowhere happens more than 30 days........." you are saying Greece is almost nowhere and thats an insult
 
I reside in the Uk so am not concerned with my iPhone 4s overheating ! Lol.

Now extreme cold and wet weather is entirely another story ! Lol.

I agree. When I'm using my iPhone for music or using Waze, it gets damn near too hot to handle. That's some serious operating temperatures.

Playing safe. In case one of the many iPhones they sold breaks down because of an extremely high or low temperature - they want to avoid law suits.

Just going to point out I made that post around 5 years ago now. This is a long dead thread that a newbie brought back.
