An interesting note...after getting my FREAK on with all of the important updates yesterday....with today's use surprisingly I am getting much better battery life and it is running much cooler..less fan if at all...Since about 9AM this morning I have been using it and I am currently at 51%....normally I would have needed the AC adapter already...I would normally get maybe 3-4 hours use out of it with fan blowing with much heat in the back...also note before the updates I did update the intel video drivers to the current one on the intel site..I had the old november 2014 drivers from microsoft update....I am quite pleased and wanted to share to see if anyone else was affected positively today like I was.
