TriciaH,
Several posts back you said you thought "media server" and "media" are two separate things, and I believe they are.
I found media server keeping my phone awake exactly the same amount of time that I have IHeart Radio running.
Media was giving me smaller useage and wake locks.
I'm no pro, but I had two things that I changed a couple days ago, and have seen an improved battery life. I was ready to do FDR 2 days ago, and now I may not.
Keeping an old theory in mind;
Apps and their respective settings on GB, may not have been set up optimally for ICS, and possible the same for the ICS to JB upgrade.
I uninstalled my eBay app, and IHeart Radio, cleared cache, and reinstalled them.
I chose those two because I use them both a lot.
I'm sure you don't use either one, but have you tried uninstalling/reinstalling any apps that you use? Even if you don't use them during the day when your battery is draining...
Even if there are apps that you don't use much would be worth trying a reinstall IMHO.
If you try, you may want to go to Settings-->Privacy
and un-check the "automatic restore". This will allow the app to be reinstalled without old settings (and data too).
I remember many threads last year suggesting that the ICS upgrade over GB, with apps left setup for GB was a possible cause for so many issues.
