    I downloaded the CoreDueTemp App and find my temperature is around 150 - 162ºF.

    The Information on the Apple Batteries page says "Your Apple notebook works best from 50° to 95°F".

    Is this relevant for the MacBooks?

    Do I have a very hot computer... or is this normal?

    By the way - I have 3 applications open - Dashboard, Mail and Safari. The computer is in "Better Battery Life" mode. Currently I can only get 1 - 1:30 of battery life - although it used to manage 3-4 hours comfortably.

    If it is very hot and the fans are running all the time - will this be having an adverse affect on my battery life too?

    The room I'm in it's about 18ºc (64ºF) - maybe a bit less.

    that isnt normal..

    I'd go to an Apple store asap.

    EDIT.

    I just checked my PB's temp. CPU is at 61°C (141°F)

    Those temps you're getting are similar to my G5 when its underload

    If that scale is for the G4 based laptops (which I'm sure ran cooler anyway) then I'm not too worried.

    What I am worried about now is that my battery shows 50% full - yet only 0:44 minutes remaining on the clock.

    Please note that the BATTERY and the SYSTEM temperature is different. Your system (CPU) is recording a higher temperature, but that doesnt mean your battery is at that temperature. CoreDuoTemp is only reading temperatures from the CPU.

    To specifications, Apple will only replace your MacBook if it reaches ABOVE 100ºc because that is when the system is TRUELY overheating. CoreDuo chips are able to operate properly until is reaches past 100ºc

    Although, compared to mine, yours is hotter if you are simplying idling there. My MacBook idles at around 50ºc

    Did the OP actually calibrate your battery within the first day or two ?

    There must be something else in these MB that some get more hot.

    Mine idles at 35C, and would rarely get above 65C.

    Thanks for clarifying that - I was getting confused between the two.

    Still not happy with the battery life - so a trip to the Apple Store for me.

    Can you check what your current maximum battery capacity is?
    Your battery life is obviously too short, so it's probably a defect battery.
    However, since you're going to the Apple store anyway, you might as well mention how hot your 'book is.
    Also, before you go, better recalibrate your battery, just to say you've done it when they ask.

    Current max capacity of battery is 4971mAh, from an original of 5200aAh. That's 95% of the original capacity.

    Thanks for the tip about the re-calibration, I will do that tonight.

    you should check your CPU usage... if a application for some reason is using alot of resources, that can be the most likely case of why your battery is being drained so quickly.

    There must be a mistake here. It can be that low. At the temp. the case would feel cold (cold).
    Or maybe you did the test just the second you turned on the MB and you had it in a room at 15 C.:rolleyes:

    My Macbook has averaged around 122 F while lightly surfing and running video off of CNN. Tonight it ran up to 165 F but I had it on my bed, so I do not think it was getting enough air flow. However, It would not get cooler than 153 F. and the fans were running full throttle. A friend had suggested that I remove the battery and power it down. The rational being that the firmware update will sometimes cause static build-up. I have had the sensor replaced a week ago for the RSS issue amd it still ran cool after that.

    I'll let you know more after I run it through the weekend.

    Cheers

    CoreDuoTemp gives wrong readings on some MacBooks. Install the newest version of smcFanControl to see your real temperature.

    CoolBook voltage?

    I use CoolBook when I'm doing processor intensive tasks. I lower the voltage to 1.0V, this is on a 1.83GHz MacBook. Great results, much cooler.
    A friend of mine has a MacBook Pro 2.16GHz. His CPU is runs fine on 0.95V up to 2GHz that is one really CoolBook!
    Apple must have gotten Intels very best CPUs.
    If someone is using this app, what are your numbers, voltage and frequency?

    Yeah, that doesn't sound right. Though I dispute that 16c would feel cold - the room temp was about 16c and the table didn't feel cold to me.;)

    Tried downloading smcFanControl and it gives a temp of 51c. So that makes more sense. Anyone know how to make CoreDuoTemp read correctly?

    Will apple replace/repair if if it gets too hot? Or will they just leave it as long as it's "within spec"?

    I have a white macbook (week 31) and a black one (week 23) I just got. At idle, using SMCfancontrol, the temp for the white one is always around ~60C while the black one is at ~50C. I can feel the black one is always cooler as well. The white one has 1.1 firmware. Would apple fix it?
