- I mean, 25% seems way too low....I would not buy the SP3 if I knew I had to go to 25% brightness to get 6 hours
Jesse – This seems to be the most common (and perhaps the most frustrating) reply. I, too, am not singling out Frank here, as his posts have been some of the most informative that I have read. He is a treasure trove of knowledge and I truly appreciate his instruction.
However, back to your original point. Almost every post about battery life is responded to by lower the brightness; yet, MS promotes the SP3 for its screen. Turning down the brightness to 25-40% seems counterproductive. If it's not the brightness, it's another concession of "turn this off or turn that off". Again, why buy such a lovely device only to diminish its capabilities?
All the tests and reviews I have seen state the SP3 will get 7-9 hours on battery. However, I have never got beyond five and I use only IE (mostly in Metro), Word and Powerpoint, and other Metro apps. The first night I used it in class was quite good; but since then, I lose about 20% per hour even at 50% brightness.
I know this forum has a certain disdain for any comparison to Mac products, but once again, I will remind other users that MS made the comparison in promoting the SP3. I have both a Retina MBP and get between 8-10 hours and never dim the brightness below 50%. I do likewise with my iPad mini Retina. (Again, I am using these two as a reference only due to the screen quality, not to get off Jesse's original topic.)
If there is a way to increase battery life without reducing some of the functionality or appeal of the SP3, I would like to know, as well.
