Is anyone else having issues with the built in battery use monitor with the extended battery? Mine doesn't seem to want to refresh or track use in real time. Mine still shows the battery use from yesterday. Not a huge deal with the extended battery as I make it through the day no problem and even had to try very hard to get the battery down below 20% yesterday just to test it out and that was after 16 hours and lots of game playing, downloads, audio streaming etc. Not sure I'm even going to use the extended battery on a daily basis since I now have a charger in my office (it does add a lot of bulk), but looks like it's going to be great for traveling or times when I'm going to be stuck in a lot of long, boring meetings and needing a distraction.
