Hi guys! So I got a new Nexus 7 today for Christmas and have been loving what I seen of it. However, I decided it might be a good idea to run it down at least once and then fully charge it again. It was like 5 hours ago now that I plugged it in. When I hit the power button, it shows the battery with lightning thing and the battery filling up. Is something wrong? Should it normally take this long for first charge? Is there a way to boot it and see what percentage it's at? Also, it came with 4.1 and I was planning to upgrade to 4.2. However I read one place that the upgrade results in performance loss. Is this true?

You're charging a fairly large battery over USB, it's not going to be blazing. The Nexus 10 is also apparently pretty bad with its charging times.
As far as 4.2 is concerned, I've heard reports of the N7 being a bit slower, but the fix is to disable Google Currents background updates, setting it to only check for new feeds when you launch the app should alleviate the issue.
Otherwise, I've had nothing but a great experience running 4.2, granted though I've been running CM10.1, a community supported ROM based on 4.2.1 AOSP.
I would take the update to 4.2, if you don't like it then you can restore it back to 4.1 via the factory images on Google's website.

when charging you can boot it up with no problem
and if you need to calibrate the battery then the process just involves running it don to the voltage cutoff point, then charging it non stop to 100% (during which time you can use it just don't unplug it)

I just received one as well, while using, I pluged it in to my PC, it barely charged within 12 hours, and then overnight still nothing, this morning I plugged it into an outlet and it charged within 3 hours, and has been fine since.
