I went to bed last night with the battery fully charged at 100%, set my alarm, and locked my screen.
Fast forward 6 hours later. My alarm goes off and I notice that my battery was at 64%... Too tired, don't care...
Fast forward 1 hour later. My alarm goes off again and I notice my battery has gone down another 5% to 59%.
I had absolutely no process running, and I had even did a reboot last night because I was having an issue with my speakers.
In comparison, my iPhone has been sitting on my desk at idle since Friday and is still at 82%...
I should say that this is the first night I've had this issue, but now I'm a little concerned as to if I should consider exchanging it for another or is this a software issue?

Update. I've restarted my phone again, and the issue seems to have resolved itself...
Here is a list of my battery drain percentage the past couple hours. I've only really been texting pretty heavily on it, but nothing else.
Notice at one point it said my battery life went from 44% to 43% then back to 44% again. Pretty odd..

If you replaced the iPhone with your 920, at this point I don't think those are fair comparisons anymore.
I replaced my focus with a 920 and my focus only lost 10-15% in its battery since about 7pm last night. Of course it no longer has a valid cell signal since everything switched over to the 920. Once less thing for it to try to connect to and keep active.
Is your old iPhone in the same boat now? No active cell connection, thus able to save loads on its battery? Doesn't solve the battery issues you seem to/were having, but it isn't a straight comparison anymore...

I just had the same problem last night. I unplug my phone around midnight after it was fully charged. And I switched to airplane mode since I don't want anyone to call me, went to sleep. Woke up at 8 am, and found out the battery was bone dry to 9% only. I put touch sensitivity low. I was shocked. This is the worst case ever. In airplane mode? Unbelievable. I've been noticing the battery issue with this phone for the past week. Didn't survive for 12 hours with little use. 4G, a few whatsapp, no call, several minutes of browsing, 5 apps running on background, nokia drive blocked, you name it. Didn't survive 12 hours. This is just horrible. I might want to sale this useless phone. I love it, but this is just unacceptable.
UPDATE (07/01): I tried a solution posted by cjlim in this forum http://discussions.nokia.com/t5/Noki...ue/m-p/1625890.
Fully drained the battery. turn on again until it dies few times and won't turn again. And then recharge it. I did this a few cycles. And now my battery life is significantly improved (200% and more). It was lasted for only 8-12 hours. Now it can last for 24 hours and even more on average. I'm a happy Lumia owner now. You guys should try this.

I had some average battery life at the beginning, but after several cycles and then blocking background operation on most apps from the settings (for apps I did not need running in the background), I have gotten much better battery life over the last couple of months. I also update all of my apps whenever updates are available. I do not know what has happened lately, I am guessing due to some app(s) updates, but my battery life has improved amazingly this week. I now get a long day with plenty of charge left when I put it back on the charger around 1am. It is 9pm now, and it has been off the charger for 12 hours, and I still have 77% left. Oftern I go a few hours before it drops below 100%. One night this week I still had 65% left at the end of the day. I do not think I have been below 30% in the last week after a full day.

One of the better features of Android is the battery usage screen. It easily lets you find the offending tasks that drain your battery. MS needs to add this to Windows phone as soon as possible.
