my macbook pro battery runs down very quickly since updating to Yosemite (and the newest Yosemite update). I have reset the SMU and the PRAM. I have an app that shows my battery health and it says it's good - however, a full charge even when I was using Photoshop etc would last all day - now I find myself charging the battery twice a day. Also, my computer is running really hot...guess that's another discussion issue. Any suggestions?
