    Post usage times and rough usage please.

    Trying to diagnose if I am having issues and need it replaced. Battery is normal condition according to the mac with only ~250 cycles with 4-5 hours usage on most settings optimised for battery life. Uses are not intense and all is turned off unless required with 30% brightness when not plugged in.

    Light to Moderate usage, Safari , Activity Monitor, Pages and Messages running = 7-10 hours
    Moderate Usage, all above running and Steam(sometimes iTunes as well, with video playback/multiple tabs occurring in Safari = 6-8 hours
    High Usage, All above, Mail, Photos, Terminal(Commands executing), Flash Player(Calls for dGPU) = 3-5 hours
    Gaming Usage(Extreme Usage) depending on the game(OS X or Windows) = 1-3.5 hours

    I typically have brightness around 30%, though I vary depending on what I'm doing or where I'm using my computer(10%-80%) and whether I know I will need to count on battery power for a while.

    Current Battery Cycle Count- 99

    Activity Monitor btw will help determine what is using the most energy on your system during usage.. hope all this helps.

    If you've got Flash installed, that'll suck the life out of a battery. I've gone "Flash-free" and have seen an increase in battery life.

    Also, if you're using Chrome, Chrome is a killer on the battery.

    Parallels running win8.1 pro (Firefox only) sucks it dry within 3 hours.

    Barely getting 5 hours with only Safari, Preview, Pages, iTunes (force quit when not using). Normal Condition for the Battery. I have the 2.6Ghz/16gb/750m/1TB.
