- macbook pro absurdly small battery life 3 answers
I have recently bought a very expensive new MacBook Pro with 8 GB memory and now I am frustrated by its very fast battery drainage. Often I see only 2 hours left on full battery charge!
Right now it is only 2:22 hours with no process above 200MB except 1 GB for kernel_task. Also 4 GB memory is free after a "memory clean" (I am also disappointed that Apple does not properly clean memory by itself).
What are possible causes of that low battery performance and how to deal with them?
Any help is greatly appreciated.
EDIT. I do memory clean with this app, hope it does what it says and not spreads a virus or likes.

UPDATE. I restarted Mac today in the morning and closed all applications - still only 3 hours. In the afternoon I have closed all applications - and miraculously I saw whopping 8 hours! Then launched Komodo and Chrome and back to 4 hours. Really puzzling...
