I downloaded Coconut Battery from online, which is freeware app. It's giving me a warning that the battery is too hot on my new Mac. Can others compare what there battery temp is? FYI, Coconut Battery also tells your Macbook's manufacturing date.. mine is April 6, 2015. The battery's age is 72 days. By the way, also used free version of Geekbench (only 32-bit is free) and it showed a score of 6267. I have the Gold Macbook 1.2/512.

Coconut Battery and OCD go hand in hand. Uninstall and enjoy your computer.

The battery on my 2013 MBA is 30.1 deg C in comparison without any battery heat warnings. I just want to make sure my battery temperature is in line with other users or if I have an abnormally high battery temperature on mine.

The problem is that high temperatures above 30 degree Celsius can damage the battery. The heat of the cpu might warm up the battery. This could be a real drawback of the fanless design.
Why isn't Apple's built in heat warning kicking in? Shouldn't his CPU just throttle and cool down or the warning pops up? Unless something isn't working as intended.

OP notice any lag anywhere when you get this warning?

I think Coconut Battery have their threshold way too low.

Sounds like you've managed to land yourself the most powerful rMB in the world, the payoff being that your battery's gonna die by the end of the year. The light that burns brightest, etc… ;)

This is one of the concerns I have about buying the first generation rMB... The CPU can get very hot, even for basic tasks, (but still within its design limits) and its going to warm up the parts of the battery nearest the mainboard. Batteries don't take kindly to elevated temperatures and their capacity will diminish much faster over time.

There was no lag at all, I had just installed Coconut Battery on it so I was just testing it out when I saw the high temperature. It was maybe 10 mins after I had turned the laptop on. It was plugged in the whole time. Upon leaving the laptop on overnight, the battery temp is now down to 29.5 deg C. What is the normal battery temp other MacBook owners are getting?

Why is it most powerful? Is it because of the Geekbench score? I noticed that others are getting around 5100-5400, but I used the free mode at 32-bit. I ran it again this morning and have attached a similarly consistent score. What are others scoring in this mode?

Lipo batteries have a working range of 0-40'c and a charge range of 0-50'c unlike lion batteries which is lower.

Another possibility is that Coconut Battery may be mis-interpreting the sensors on a brand-new MacBook. The battery _may_ tolerate, and report, much more internal heat, because of the distinctly different physical layout (much less space inside) in the new MB.
You might want to contact the developers of Coconut Battery. They may even have a test version that you can download, that might give you better details about a very different internal hardware.

That's interesting, why is mine running faster with the same specs?
I wonder if it has something to do with the throttling in place to keep the temperatures down. That would explain why yours is running hot. Maybe something, hardware of software, was left out on your macbook. It is not throttling like others are.

this is also very possible, but the scores of his geek bench are much higher than others.

But my GeekBench score this morning was the same high score as yesterday, except this morning my temperature was low at 29.5 deg C. The temperature was only high at the time of original posting, but Geekbench scores were tested in both circumstances.

High temperatures of 86 degrees fahrenheit? That's, uh, more than a bit overblown there...

Last I checked, the typical range for charging a LiPoly battery is up to 50C. (And these could have been specced higher, given the nature of the machine.)

I just noticed you're on GeekBench 2. If you want to compare apples-to-apples you're going to have to use GeekBench 3.

You seem really curious about why you posted higher. For 10 bucks you can find out.

35C too hot? LOL! The Core M doesn't hit its max until 95C. I was able to run 84-87C exporting to iMovie for 24 minutes with no problems. 35C is nothing.

In the case of the rMB, the battery is spread out in the case and most of it is not anywhere near the CPU so it will probably not be a problem.

I have a mid 2015 15" MBP and Coconut battery is giving me the same warning. I think the app is junk. Google search brought me to this thread.

The app is ok and has it`s uses, however the battery temperature monitoring is a new feature and it`s potentially not dialled in yet. So far it has not triggered on my 12" & 13" Reina`s, it has trigged in my 15" Retina. If your concerned just turn off the temp monitoring in the preferences.

The other way to look at it, you now have a wanring that the battery temperature is escalating and take action, such as elevating the Notebook. The Dev is simply being conservative.
