Battery sometimes not loading when it is warm

After a heavy usage and when the computer and the battery is warm, I realised, that the battery will sometimes stop loading and after a while of inactivity it will start to load the battery, again.

So is it right, that there is a algorithm running in the background of OS X, which will stop the loading while the battery is warmer than it should due to a heavy usage of the macbook? So that the software is regulating the loading to improve battery life and this should not be a hardware issue?

Lithium Ion batteries have an ideal window of charge when you try charging the battery outside of this window the charging logic is designed not to temp fate!

So depending on your ambient temperature, the battery state, and the usage that is currently under all affect the temperature of the system and if the temperature is in the window space of chargeability.

To improve the temperature so it is more likely to charge you need to have a cool place to sit your system on, as well as the ventilation of the system is not blocked and if you can change the temperature of the environment, that will also help so using the computer in a cool room can make a big difference.

So you would rate this a normal behavior, right?

There are no issues with the fans or so on, but sometimes it gets warm as I use apps which have a high energy demand and in warm places it is not possible to get it cooler after some hours of work. Best

@hirsch75736 - This system is running way too hot!

What are you running for processes? What is your environment?

This series was the start of Intels downfall as the CPU’s process Node that was expected to offer the needed thermals given the chips design was not used. Apple’s ultra thin design needed the better chip Node, they gambled hoping people wouldn’t push the system, but of course they did !! And it looks like your one of the many that have.

You will need to alter your use or need to jump to a MacBook Pro that offers an M series chip as Intel couldn’t produce the chip and even today is not able to produce chips that keep up with the others.

Hi @danj , so It's a problem by design, as I read your comment and as long as I can use my Macbook it will not cause any harm but sometimes the Macbook has to cool down a little bit, before the battery starts to load again, right?

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

@hirsch75736 - Intel's and Apples wishful thinking this series could be a Pro's system, it was not a true MacBook Pro, it's nothing more than what a lower end MacBook should have been.

While on the short term your approach will work, the batteries chemistry will be harmed from excessive heat damage shortening its life. That is if you run the system as hard as you appear to be doing. Make sure you lessen the number of open tabs in your web browser, don't rum heavy graphic games that over tax the GPU & CPU, and lastly don't process (render) or create images with lots of objects or layers.

@danj o.k. but it is not caused from a bad ifixit battery, right?
