So since the battery is not replaceable on the SP3 i was thinking its even more important to try to get the battery to last as long as possible. And there is a ton of info on the internet, the problem is that they all say different things, so it´s hard to know which one is the correct answer. I´m thinking first and foremost about the charging procedure, what is the best way to charge the battery in order to get it to last as long as possible? Some people say that when you are home near a power outlet you should let the charger be connected to the SPx at all times while others say that is not good for the battery. I know that heat is the number one enemy to batteries, but theres only so much one can do about the heat in the SPx. Also i have been reading that the battery should not be charged full and not discharged below 10 percent. That leads me to my next question, so is there any way on the SP3 to set the max charge for example to 60-80 percent or something like that? I know this can be done on certain laptop brands that uses their own power management software, i think on Lenovo and Sony this can be done. Can this be done on the SP3 as well? Maybe this setting is available in Windows 8.1? I would be glad to get some answers to my questions so that one can try to preserve the battery life as long as possible.
