    Don't obsess about battery health. Batteries deplete naturally over time, they fluctuate, they die; it's the nature of the beast with lithium.

    You won't see a real-world difference in battery life with anything from 90% anyway. Delete the battery app, don't worry, and just enjoy your computer as you should.

    The negative number indicates the battery is discharging. You will encounter this if it's not on charge and it's running on battery only.

    Again, honestly, no need to worry about any of this. Ditch the battery app and just use it how you want to! There's little point in obsessing over battery health as there's nothing you can do to ebb the flow. If you've got AppleCare, Apple will replace the battery if it begins to fail within the 3 year period. So honestly you shouldn't be concerned.

    If it's anything like with other unibody machines then it's always a bit inaccurate. The trick to make it accurate, i.e "calibrate" it, is using the battery until it's almost completely empty (less than 5% capacity), shutting the machine down completely and letting it recharge until it's full. When this is done it should show the accurate figure as to the condition of your battery. I've personally had it move by a few percent in either direction when doing this.

    This is accurate advice but please be aware that if you were to do it, it should be a one-time thing only. Frequently running full cycles on the battery will only wear it down quicker.

    However OP, it's not necessary to do by any means. Again stop worrying about the battery, get rid of the app, cut the paranoia and use your machine normally!
