I noticed that the longer I keep my 920 on the charger = the longer it can last off charger.
On Friday, I charged my 920 for a couple hours and got it off charger as soon as I saw it had 100% of battery. But then with very light use, mostly on stand by, it dropped around 5% or so. I decided to put it on charger again when I went to bed, because I was going to a road trip on Saturday and I didn't want it died on the road. So it was on charger for around 8 hours, and I pulled it off charger around 8:30 am on Saturday.
Here is what I did with the phone: I made several short phone calls( less than 5 mins each), played games for about 5 mins, took pictures( not a lot pictures, and they were uploaded to my skydrive), emailed back and forth for a little bit, surfed the web for some info, and some chatting on apps and texting as well. And now, my 920 still has more than 40%. I am very satisfied with this battery life. Let me know if this helps your battery life as well.
