Poor battery life and high temperatures on MacBook Pro Retina 15"

I'm having never-ending problems with poor battery life and high temperatures on a MacBook Pro Retina 15"
I took it in for service and they told me it needed a new logic board and replaced it. When I asked why they were vague about the reasons, they said "it just needed one, it failed some test". I now have the computer back and it runs the same way it always did. I bought this laptop because it was supposedly capable of high end video editing in 1080P (or so Apple's website claims) and also photo editing.
"The processor, graphics, all-flash architecture, memory, and display in the 15-inch MacBook Pro give you unprecedented mobile video editing capabilities. Super-responsive flash storage delivers up to nine streams of 1080p ProRes (HQ) content for multicam editing in Final Cut Pro X,3 while the latest quad-core processors on the 15-inch MacBook Pro decode multiple streams of video, and a powerful GPU renders millions of pixels onto the screen. With flash storage that offers up to four times the performance of a traditional hard drive,1 you can even edit four streams of uncompressed 8-bit 1080p HD video, right from the internal storage on your 15-inch MacBook Pro with Retina display.4"
However, when I'm just browsing the web and emailing it runs quite warm and battery life is quite poor. Sometimes doing those same activities I would say it gets so warm it's almost uncomfortable to have on your lap and the fans are running fast enough to become noticably noisy. I'm also driving only one screen at and a time and I heard that the MacBook Pro can supposedly do three screens.
If actually try to do something like video editing with final cut pro the laptop gets really hot, the fans are on full blast and battery life drops to only an hour or two. I think when I rendered just a 3 or 4 minute clip once I got less than hour of battery life. I will have to time again.
Anyway most people (including the sales guys) are telling me no way this is not normal. When I play with demos in the store browsing the web they are not getting warm or hot to the touch. My friend's 2013 MacBook Air is also NOT getting warm to the touch doing the same activities.
I installed iStat Pro so I could check the temperature and fan speeds. I'm seeing temperatures of 70+ on the GPU, 85+ on the GPU diode and 65+ on the CPU heatsink along with elvated fan speeds above 5K which becomes noticeably noisy. I understand that might be normal for the most processor intensive tasks but it really doesn't seem right for just light web browsing and e-mailing. (I also may have viber and skype open but that shouldn't matter). CPU usage is usually running between 2-10% as this is all happening to.
Furthermore, straight from the specs:
Intel HD Graphics 4000
NVIDIA GeForce GT 650M with 1GB of GDDR5 memory and automatic graphics switching
I am assume "GPU" and "GPU diode" are temp measurements on the discrenete NVIDIA video card, especially since MacBook Airs from the same and newer generatio do not have this reading. Since Apple Claims the graphics "automatically switches" it seems all the harder to believe the GPU is reaching 85+ when in theory it shouldn't even be activated. I mean, shouldn't the INtel HD Graphics 4000 be capable of simple web browsing and e-mailing? Especially with only one screen activated (be it it the internal or an external)?
What should I do here? When I asked the repair guys "OK well what is the normal operating temp range for the various sensors" they said "Sorry Apple doesn't provide that info".

Yes I have.
Just web browsing and basically doing nothing I'm hear a lot of aduible fans, I'm getting 85C+ on GPU diode, 65+ on cpu heatsink. I since installed anohter program that shows me not just the CPU heatsink but the cores and the cores are at 90C+.
Seems like a lot of heat for doing nothing. Not only that but I have these problems with no external monitor while on battery power too.
I don't know what to do. They already replaced the logic board. Others seem to get advertised battery life out of Apple products and not have products that get **** near hot enough to burn you while just web browsing or watching a movie let alone advertised tasks like Photoshop and Final Cut Pro.

Latest MBP and high temperature ?

Does anyone who bought the latest MacBook Pro have any problems with is heating up extremely ?

Not sure what you mean by extremely, as that is a subjective term. If you read the manual the bottom, actually entire case being aluminum, is part of the cooling. It will get hot enough to be uncomfortable on your lap. Despite the term laptop, NO laptop computer should be used on your lap.
I have a new 17" MBP purchased July 1, and only when gaming do the fans start spinning fast, even then only occasionally.

Is the device safe as long as there is no high temperature screen?

Sometimes I use the phone in hot environment, a bit worried if the heat could damage internal components.
So how good is iPhone's self protection against high temperature? Can I say that the device is safe as long as I don't see a high temperature warning screen?
If the heat comes from outside, the screen and metallic chassis should have some ability to dissipate the heat and shield it away from internal parts right?
Thanks for your answers in advance!

This is the specs:
Environmental Requirements
Operating ambient temperature:32° to 95° F (0° to 35° C)
Nonoperating temperature:-4° to 113° F (-20° to 45° C)
Relative humidity:5% to 95% noncondensing
Operating altitude:tested up to 10,000 feet (3000 m)

Iphone 3Gs high temperature and low batterie performance

Hello,
This is my first question here, so I'm sorry if I doing something wrong.
About a week ago my iPhone 3Gs is demonstrating very high temperature, at any location (inside my pocket, over my desk e etc...) and situation (it happens even in airplane mode), not enough to a overheat warning dough. And his battery dies in about 1 hour, no matter what I do. I've done a recovery and its came back to normal for 2 days, but after that the heat and battery problem has returned.
Could any body help me?

Recommended!
Hot phone and battery drain, cause of both together, is some hardware defect as a micro short-circuit (the phone dropped in water, as example) or an app who have a bug who let it eat all the energy (keep on localization services, as example).
Let the phone hard reboot, too, to remove any crazy process left in.
If you still have the issue with nothing running on (please make sure really nothing is on, neither background apps or itunes songs or anything else), most likely is hardware defect and you need service, as pointed above.

My iphone shows high temperature last night and today is off and dont want to turn on what cani do?

MY phone shows high temperature and then went off what can i do? Is it damaged?

Here are some troubleshooting steps you can perform to try and get it started again: iOS: Not responding or does not turn on - Apple Support

I had a temperature warning come up on my iPhone 4 and now it won't turn on

I had a temperature warning come up on my iPhone 4 saying I needed to cool it to use it or something and turned it off and attempted to turn it back on as a means of fixing it, but it didn't work and now my phone isn't turning back on and even when I connect it to the charging cable (either to a plug socket or iTunes via my laptop) nothing happens; it doesn't even seem to detect it, my phone is still lifeless.
Anyone know what to do about this and how to fix my phone again? Cos right now, it's nothing more than a nice looking paper-weight. Would appreciate the feedback, thanks.

Try a hard reset while connected to power: (adapter, not iTunes on computer): Press and hold both the Home button and Sleep/wake button at the same time for about 15 seconds and release when the Apple Logo appears.
If this doesn't work: try to force restore: http://support.apple.com/kb/ht1808
NB: the article above will erase all data and content, so make sure you've got a backup
Good luck

Hey, I've got the same problem. Did you find any help or solution by now?

After backup, TM cannot eject itself automatically, and then both my mac and TM get high temperature. why is that, I had the same problem twice.

Are you saying, right now that the TM refuses to work even after a re-boot?
Is the light solid green at least?

Please i need help. My iphone 4s have a temperature warning then the iphone turn-off right away and no matter how we press the power button the iphone doesnt start..please help me.

i already charged it but nothing shows in the screen.. i did the long pressing both home button and sleep/wake button still no result.. please help me..

If it has a temperature warning, you may have over heated it. Keep it inside and at a cooler temperature exposure. Give it some time. Try holding down the home button and the power button at the same time until something happens.

I have a SC-2042-RTD Board and the temperature reading I get are approxiximately 7 degrees high. Every thing is connected as specified in the manual. We are using a 3 wire RTD configuratuion.

I have a SC-2042-RTD Board and the temperature readings I get are approxiximately 7 degrees high. Every thing is connected as specified in the manual. We are using a 3 wire RTD configuratuion. The current excitation is set at 1mA but is actually 1.0035 mA from the board. The Daq card I am using is a DaqCard-A
I16XE-50.

Two quick things to check are: make sure the sensor does not exceed a max resistance of 8.5k ohms and do not leave any current excitation sources unloaded.
Also, check out chapter five of the SC-2042 user manaul (attached) about how to calibrate the device. This may help get rid of the bad readings.

GTX 560Ti Hawk high temperature and noise

First of all I want to say "Hi" because this is my first post here!
Second, I have problems with my GTX 560Ti Hawk! The problems are high temperature and very loud fans! I bought this card less than a month ago and it didn't work properly from the first day but I wanted to give it a chance so I kept it for a while so I could monitor symptoms. I haven't even tried to OC it. I monitored it the way it came from the box.
In idle card doesn't go over 40°C which is fine by me considering the weather but when I play games it goes all the way to 85°C and it's loud as jet taking off! It's is pretty much intolerable to be near this card when playing games! This product is advertised to be very cold and very silent but now that isn't the case. What bothers me most is that the card was running on open bench table which has very good air cooling ( I made it myself and decreased ~10°C compared to my case). That means that my Hawk would have burned if tested inside the case, or it would fly away!! :D
Everything is good until card hits 76°C - that's tolerable temperature and the card is still silent, but when it hits 76°C and goes up, all hell breaks loose!
Card doesn't crash and it runs perfectly (got performance increase ~30% from my GTX 460) but way higher temperatures and noise above advertised makes me wanting to crash it with a sledgehammer! :D
I RMA it today and waiting for answer which should arrive in two weeks tops (quick when taking money but very slow when support is needed)
I wanted to ask if RMA is even possible when card isn't crashing??? I RMA cards with similar problems before with no problems but that was Gigabyte - not sure what can I expect with MSI because this is my first MSI product since 2003. RMA should be possible because card has failed to fulfill expectations which are guarantied by MSI...
If they refuse to send another card or return the money, what should I do???
Computer specs:
AMD Phenom 2 X4 955BE
Gigabyte GA-790XTA-UD4
2x2 GB DDR3 Mushkin Blackline Stiletto
MSI GTX 560Ti Hawk (previously owned Gigabyte GTX 460 768MB which never went above 65°C even highly OC-ed)
Seasonic 620-GM
Patriot Pyro 60GB and WD 640GB Green
Thank you!

Not Charge
- See:
iPod touch: Hardware troubleshooting
iPhone and iPod touch: Charging the battery
- Try another cable.
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic. I suspect this is your problem
- Make an appointment at the Genius Bar of an Apple store.

Crash on iOS with air 3.8 and higher

Hello,
We have an application we are deploying on PC & Mac using the FlashPlayer. We are porting the application on Android and iOS using Air Sdk. The application runs perfectly well in terms of performance. The game runs without any trouble til the end on Android but we are experiencing a crash on iOS.
The crash seems to be related to a memory issue. We profiled the application with Instruments and when the crash appears, the application consumes 90Megs of memory. This is for an iPhone 3GS. On an iPad2, the game crashes similarly around 100Megs of Ram used. The crash log refers to a bad access exception and as we are receiving a lot of low memory warnings, we assume it comes from a malloc that fails.
We obviously don't have any leaks left as the game runs well on all the other platforms. this is especially obvious as the game runs perfectly well on Android with the same sdk. We are rendering in gpu mode. We also tried to switch to cpu without any luck. The garbage collector seems to be triggering well as we can see the live bytes going down regularly depending on the clips being played.
What we don't understand is that the crash log says we are using around 50000 rpages, which corresponds to a total memory of 200Megs (4k per page). This is weird as Instruments tells us the application consumes 90Megs of Ram when the crash occurs.
The only big difference between the iOS and the other platforms is that the swf assets can't be unloaded. Therefore, once loaded, they stay in memory. Still, we tried to use as much movieclip as possible so we can stop them and remove them from the scene when they are not needed. This, to make sure the display data are released as often as possible.
Do you have any kind of advice to solve this issue ? This is becoming quite urgent as the game is finished and this bug prevents us from releasing the master build.
Regards.

Hi Chris,
We found the crash on iOS7 devices. The game native display is 16/9 so depending on the devices screen resolution, we have to apply black stripes on top/bottom of the screen. To make sure nothing bites on those stripes we have a mask applied directly on Lib.current. If we get rid of this mask, no more crash on iOS7.
The funniest thing is that without this mask, we also managed to reach act 6 on iOS6 and lower. Before that we couldn't get pass act 3. We are currently trying to remove all the masks we have to check if this solves our problem.
Does this pop something in your mind ? Could these masks lead to memory leaks on iOS devices ?
Thanks,
Philippe
