Some Overheating 3GS iPhones Glow Pink

Hugh Pickens writes "The Telegraph reports that dozens of users of the recently released iPhone 3GS have reported overheating issues, with some iPhone owners unable to pick up the device because the handset gets so hot to the touch, while others say the casing turns pink with the heat. 'I am definitely experiencing issues with the iPhone running warm and quick battery life lost,' writes Tom Goldstein on one discussion board. 'The phone seems to warm up almost immediately if I am doing anything that pulls data over the network.' Some users have said the device has been too hot to put to their ear while making a phone call, and others say the overheating seems to occur when owners are using the iPhone's mapping software, which uses the handset's built-in GPS technology. Melissa J. Perenson writes at PC World: 'I became aware the handset had become very hot. Very, very hot — not just on the back, but the entire length of the front face, too.' Some gadget experts believe faulty batteries could be the cause of overheating and poor battery life. 'My guess is there's going to be a whole lot of batteries affected because these [iPhones] are from very large production runs,' said Aaron Vronko, who fixes iPods and iPhones. 'If you have a problem in the design of a series of batteries, it's probably going to be spread to tens of thousands [of device], if not hundreds of thousands, and maybe more.'"

  2. Android G1 also heats when using GPS by Simon+Brooke · · Score: 5, Interesting

    My Android G1 - normally cool (in the thermal sense) heats quickly when using GPS for sustained periods. It doesn't become uncomfortable to hold or to use but it's definitely noticable. My bet is that the iPhone problem is also GPS related.

      When I truck a lot of traffic over 3G to the G1 I also seem to have some overheating problems, albeit not as severe as those being discussed above. Notably trying to watch TV in beebplayer seems to cause overheating which may or may not be why the video often halts for me in that application. That might tally with those proclaiming general traffic as being a problem too. PS. No idea why you've been modded off topic, since a comparison of similar issues with other phones seems highly relevant to me. Had I mod points I'd have corrected that.

      My bet is that the iPhone problem is also GPS related.

      My somewhat ancient Garmin GPS runs for somewhat over a day continuous on two AA batteries. It has a nice full color screen about the size of a iphone although much lower resolution. It is an inch or two larger than an iphone in all dimensions but that's mostly empty space... its engineered to be less dense than water, so as to float.

      So, thats about 3 volts at about 1.5 amp-hours equals about 4.5 watt-hours.

      Dividing 4.5 watthours by a pessimistic 24 hours, gives 188 milliwatts.

      I'm sure a decade or so newer engineering results in much lower power consumption. Checking out the technical specifications PDF for the first google I found:

      http://www.latitudetechnology.com/gps_module.html

      You're looking at about 23 mA at about 3 volts, for a whopping 70 milliwatts, almost a third less for an "april of 2009" GPS module. Technology marches onward I guess.

      1) A quarter watt dumped in a case that large is not going to be detectably warmer, but it'll probably be almost enough to stop dew from condensing on the surface, most of the time. Dew will condense on the surface of my powered up GPS in extreme weather conditions. To get "warm" with a quarter watt, compare the tiny volume and tiny surface area of a typical quarter-watt power resistor to an iphone.

      2) Considering handheld cellphones are allowed to transmit 600 mW and I suspect the overall RF section is less than 50% efficient, the phone probably dumps at least 3 times the heat from its RF section than its GPS section. Then probably about half the emitted RF gets adsorbed by the users hands, figure about a watt of total heat in the hands just from the transmitter. GPS or no, will not be noticeable.

      The problem is not the GPS module. Now a GPS application could "require" a multi-core GHZ class pentium processor at full blast, but thats a software engineering problem not a "GPS" problem, since obviously a "real handheld GPS" does the same task without turning into a handwarmer. A bad enough programmer could make a tetris that would burn your hands, but that doesn't mean tetris is the problem.

    Apple can just deal with this like everyone else, right? You know, send a whole bunch of batteries to the retail stores, and those affected can come in, pop off the back of the phone, replace the battery, and drop off the old one. No need to send the phone back or anything.

      Some people on Palm boards or literally on their THIRD PRE because its so poorly constructed, yet a handful of iPhones get hot and Apple is this awful company.

      I realize that in Macfanboyland this probably isn't true, but in the real world, it's possible for two companies to be bad at the same time.

  5. There's definately an issue of some sort by Cyberllama · · Score: 5, Informative

    I think there is a software issue that causes something to start draining power at a crazy rate non-stop. I turned on the percentage battery indicator on my 3gs and one day I noticed it was running kind of hot and I looked at the indicator and saw the battery % had gotten crazy low really fast so I just set the phone down and watched.

    I was losing like 1% every minute while running nothing other than the OS itself. WTF? That's like under 2 hour battery life while doing NOTHING but staring at the home screen -- you're supposed to be able to watch video for 6-7 hours, right?

    So I powered my phone off completely, then let it reboot. Whatever it was, it went away. After that it ran smooth, no extra heat, battery indicator stayed at the same percent as I stared at homescreen for 5+ minutes and it was perfectly fine for the rest of the day. No clue what happened there, but something was draining power non-stop until I rebooted the thing. I assume it wasn't the processor, because it wasn't locked up -- so perhaps it was a modem issue.

    It's quite possible that had I not noticed this issue and rebooted my phone I might have ended up with a pink one as well.

    How could I figure the huge CPU load? Simple, battery went hot and died in hours. It is like old fashion way of figuring CPU load.

    What I mean is don't eliminate CPU immediately, they are portable devices running portable CPU which was never designed for 24/7 full CPU load.

    What we need is, some heroic blog hack the iPhone 3G, install standard UNIX tools (ps) and run ps -aux (or top) whenever it gets hot. I am NOT suggesting it to actual iPhone 3GS owners.

    Look at it this way. The device was nearly certain to be huge. However, prior to it's actual launch, who would finance a massive facility to make tens of millions of devices America had never seen?

    Apple has "rolled out" their iPhone in the same way the did with the iPod.

    They're STILL building new facilities to handle the market load of ther device. Same for their Macs. They COULD be a lot more popular, but Apple simply doesn't have a CAPACITY to build enough fast enough if the device was actually 100% perfect. They also don;t have the staff to support a user base growing on that scale. even with their slower adoption they're having major staff issues, even 2 years in...

    Oh, and it does multitask, allways did. Wuit the "background" argument already. I'm sick of it. Short of them needing a "plug-in" system for the iPod interface, so things Like Pandora can use it's functions as a background app, i can't find a single reason why suspend (sleep and resume without using resources) and notify (same thing as backgrounding in my opinion, and easier to code for) functionality isn't equally as good. The only thing they're missing on top of an iPod plug-in is for multiple web pages to be loading, or downloading docs, concurrently. But Mail downloads in the background, SMS runs in the background, so does the phone, name any one app you background on another device that we can't do exactly the same thing with on the iPhone without "requiring" backgrounding... No one has yet given me ONE, not ONE.
