Battery life getting better with a few charges, it seems

    (11-inch, to clarify)

    It seemed before when I tested my battery, my computer would read its % life going down pretty fast. I'd hit 90% (from 100%) in about 15 minutes. Which amounts to (if held true through the entire charge) a 2 hour and 30 minute battery lifespan.

    Now I've been testing again:
    - 35-40% brightness (switching between 5 & 6 bars brightness level)
    - backlit off
    - app store in background
    - constantly browsing
    - 1/3 of the time (exactly 10 minutes out of every 30 minutes) running a youtube video

    I get just under 12% battery discharge over 30 minutes (rounded to the nearest quarter percent I'd say about 11.75% based on watching the % drop and time move). 10% would be exactly 5 hours. Pretty decent.

    Overall I'm much more happy with the battery life. The battery life counter absolutely blows though. It's reading 5 hours and 23 minutes left on my battery, with 86% charge remaining. I know in a couple minutes it will likely drop down to 3 hours and 56 minutes, or something like that.

    Would anyone else like to share their battery life observations? Start from a certain percent (I started at 98%), and start at a certain given time, and record your battery life over say 30 minutes / 60 minutes / 120 minutes, etc, etc. I'm testing through right now (since I'm within a 2 week return period and just want to be 100% sure everything is proper... which it appears to be).

    I still wish they could manage to put the Macbook Air 13-inch battery into the 11-inch!!! :D

    I'm trying to get a different perspective on battery life, how about looking at how much power being used by looking at the CoconutBattery?

    I started this thread earlier anyway, it'll be great either contributing here or on my thread (sorry for the hijack):
