I had asked the question before, but had to leave unexpectedly before I got an answer. Belodion had asked me for battery usage stats but I couldn't find a way to respond since it had been 3 hours. The battery is just 7 months old, and I don't use the phone a great deal.
I checked the drainage for parts of 2 days, and found this:
Saturday 6:15 a.m. (the System Power Saving app was the only one on) and the battery 100% At 8:00 a.m. 65%. I turned off the app and the phone was idle until 10:15 a.m. when it was at 20%.
Sunday 2:30 p.m. 100%. 5:30p.m. 38% (idle the whole 3 hours).
Some time ago I went through the apps and deleted all of the ones I didn't use.

It's pretty easy to do.
