I know I'm probably biting the bullet on this one, and it's been asked a HUNDRED times before, but I've tried all of the usual stuff and my macbook battery is still pretty average compared to what I thought it should be. I've heard that keeping the macbook plugged in can make the battery worse, so I try to keep it unplugged for as much time as possible, but I'm a writer so it can prove difficult at times when I need to write for long periods of times. I've got my brightness turned down to the minimum, keyboard backlight is off completely, bluetooth is off, I've quit as many apps as possible (I have the ones I'm using running). Is there anything else I should think of doing? If I turn Time Machine off will it still remember my backups from previous times? I know that having Wifi off completely would probably help in the long run but I have to use the internet a lot so it would be frustrating having to turn it off and on whenever I use it.
