    How long would you say the avg battery life in a 15inch rMBP using 25% brightness? 3 years or much longer?

    Are you talking total useful life? Screen brightness has little to do with it. I know people who are going on 4-5 years with their MBPro and the battery still takes care of business. Total charge and discharge cycles determine a battery's lifespan along with charging habits.

    I use my laptop while plugged in about 80% of the time but others hardly ever use a charger while using the device.

    Best thing to do is just use your laptop and enjoy it. Charge it when you want and enjoy!
