Seems like this is happening to more and more people. I'm assuming its in correlation with us downloading more apps as it seems some of them don't "turn off" when we close them. I've had this problem for about two weeks now. Don't really know the culprits and to be honest I only have about 8-10 apps on the thing so I'm worried about downloading more.

I can definitely see that there may be a problem but that said, why exactly would you go to sleep for 7 hours (or more) and NOT plug your phone in? I know other people who do this and I just don't get it. Even if the phone doesn't go down to 0%, it just seems silly not to plug it in. One can assume that after you wake up, you're going to be awake for a while and need/want your phone pretty much at 100%. It will always go down some amount when you leave it sit that long. I always plug my phone in when I go to bed regardless of how much is left on there simply because I know I will want it at 100% when I wake up. P.S. Also never understood anyone who depends on cell phone alarm. To many things can go wrong there.Connie L - Windows Phone 8 always

There is a bug with Gmail accounts constantly syncing. This killed my battery life.
What Are the Gmail Exchange ActiveSync Settings? - About Email
See what happens. It took my battery life from 5-6 hours with normal use to 1-2 days.

1) Plug in your phone at night
2) hammer the back arrow repeatedly to exit out of all apps before you go to bed
3) Settings->Applications->Background processes - find out whats running, decide if you need it running in the background, turn it off if not.
Those are the first three, let me know if you need more solutions.

Back to the issue, is the battery draining repeatable? Occasionally I notice the battery seems to be draining much faster than excepted but never seem to be able to reproduce it. Perhaps I should be more patient and not reboot it at that point.

How dare OP assume his battery isn't going to die when his phone is at 70% when he goes to sleep.
Here's something useful OP, check the threads for improving battery life. Also do a back up of your phone and consider restoring it. I did the same and found better results with my battery.
Hope this helps.

I agree with the tip about the back arrow. Back up till you cant go any further.
I had a similar problem. I think that the Draw Something game (which is a well-known terrible port) was eating my battery. This is because it shows tile notifications even when you turn them off, and turn off syncing with xBox. So I'm 99% sure there are some apps out there that were coded poorly and don't follow the rules.
I resolved my issues by taking the following steps. Now I drain at 1-2% / hr.
1) Hard reset phone
2) Before installing any 3rd party apps, go through every crevice of every setting and app. Disable anything (WITHIN REASON - For example, do you really need WiFi on all the time?) that you suspect would eat battery or connect uselessly to the internet. After you get a baseline of your new battery performance, you can re-enable things as desired. Make sure to enable battery saver mode for when your battery gets low. That's a good failsafe.
3) Set up all of your accounts (email, Facebook, etc.)
4) Set email to SYNC "as items arrive". From my experience, this actually uses less battery. Defies logic, but it definitely seems that way. I use 2 accounts: Outlook.com and corporate Exchange. So I don't know if Google sync is an issue, but I'd be willing to guess ;-)
5) Install 3rd party apps (no games yet), one at a time, and tune the settings of each one after you install it, before moving to the next one. Make sure to check if each one is running a background service, and disable it. I only have one background service active (My Stocks Portfolio live tile).
Charge it and use it for a couple of days. Things should improve greatly.
Then you can go install games and see if that's killing you. I'm going 36 hours between charges. The point is to start with a fully optimized system, and not pile on all of your apps and games at once. Optimize the settings, then install apps one at a time, allowing enough time between the killer apps to adequately gauge battery life. It requires patience. But it's the only way you're gonna figure out the real culprit.., slow and methodical process of elimination. For me, it was very well worth it.
I don't think there's anything wrong with blowing up your phone a few times (i.e. hard resetting) in order to figure out the configuration that works best for you. But I came from the wild wild west (a.k.a. Android), where I was hard resetting every 4 days to try to figure out a way to get my battery to last over 5 hours. I don't miss that.

I'm sorry, but there is absolutely no reason he should have to plug in his phone at night if he doesn't want to. Anyone suggesting that he should somehow have to worry about his phone idling from 70% to 0% at night is an *****. From 70% to 55%, sure. But NO ONE using a modern smart phone should have wonder if their alarm is going to go off when they leave it unplugged at 70%.

I would try just cycling the power of the device, i.e. power off in the normal way and then power on before going to bed and then put it into stand by.
I have noticed that when my battery has been draining faster than usual (occasional) then power cycling works. It works very well if you power off, allow the device to cool down and then power back on.
I think that there is some sort of feedback loop/thermal runaway thing going on here. The hotter the battery is the quicker it discharges, the quicker it discharges the hotter it gets, and so on. Getting it cooled down seems to significantly reduce discharge rate.

The only time my battery had abnormally drained was when I accidentally hit the Nokia Drive app, then hit the windows button, and forgot it was running in the background. The GPS polling killed my battery in 4-5 hours. That's one app I removed from the start screen so that I don't ever accidentally hit it. I love the drive app, but i'm also very careful to back back back out of it when i'm done.

Yeah, no reason to turn off your phone when it's at 70% prior to hitting the hay. I mean, I get 2 full days out of my phone with minimal use, so that also implies I'm not charging my phone when I'm going to bed.
Though I still have to reboot the phone after it comes off the charger. Simply because it will have an unusual high drain otherwise.

I'll chime in with some of my discoveries. I had a weird volume issue with my first 920. I exchanged it, and my new one does the wonderful locking up, but only every 3-4 days. Since this phone likes to lock up when left on the charger, I have been experimenting with different charging times and watching battery life. On to what I have learned.
I installed battery sense on this phone, and uninstalled it to try to eliminate the locking up. When I uninstalled it, I realized my battery actually lasted much longer. So, my experience tells me, the battery apps while nice, they do chip away at your battery.
Also, I installed bringcast to catch one of my favorite podcast that I can't get through the marketplace. This app sucked my battery dry. Like 10% an hour or more while idling. The app is allowed to run in the background, and the phone won't let you control it (under the advanced section of background tasks). There may have been a setting in the app that I missed to solve this. Once I realized how it drained my battery, I uninstalled it.
Last thing here. I worked a night shift last night, and to start the night off my phone was losing battery life quite quickly. It lost 15% in less than 2 hours, with very little usage. The strange thing is, it didn't act up yesterday. Well, I ended up charging my phone fully while I was driving. I took it off the charger at about 9 PM, and a little while later, it locked up a little differently than usual. I did a soft reset, and since then, it has been fine. The phone is currently at 42%, and I'm typing this long message on it. Honestly, I'm amazed at the life I can get out of my phone. One day I had my Bluetooth headset on standby for 8 hrs, I talked for a little over an hour during that time, I played about 15 minutes of games during the day, when I got home I used my phone like normal (surfing the web, reading WP Central :), and playing games) and I went to bed with over 40% battery left. I'd say don't be afraid to experiment. Check the advanced menu in the background tasks area, and try to eliminate the pigs that are unnecessary. Also, you mentioned that your phone gets really hot. Whatever is causing that, is more than likely the culprit, more than anything. That heat is just wasted energy. Hopefully the new phone will serve you much better.

Plug your phone because you never know when your phone will go down from 70% to 0%. I've had it happen to me with an iphone, focus s, ..
Plug my phone every night no matter what unless im testing to see if there is an idle drain.
Whether he shouild or not have to plug his phone, if he wants to be safe, plug the phone. Not everything happens as you expect it to happen.

My battery life was crazy good. I would only lose like 6-7% over night. Then out of the blue I could lose like 60% or more.
To the jackasses who say "PLUG IT IN DURRRR" - shut up.
Nokia, Microsoft or the devs of whatever app is causing this drain need to fix the problem. When the hurricans ripped through my state we didn't have power for days. My cell stayed charged for 2 days with minimal use. If that happened now my phone would be dead within 18 hours tops without being used at all.
I am tempted to hard reset my phone and only install what I need for apps (I am an app horder) but I shouldn't have to do that. The battery should be better - end of story.

I just want to say Holy S***, some of you cats are real Blowhards.
Sure I usually charge my phone at night, like to keep it above 50% [battery university], but it is anyone's prerogative to choose to do as they please with their.
Consistent 920 battery issues are ridiculous. You users should not settle, high battery while idle is crappy. WP8 need to better regulate background processes?
Nokia is not new to smart phones. 1~2% battery loss over 8 hours is excellent, 3~6% acceptable, 10% high, and going dead abysmal. Why rationalize that?
And confirmation bias in the air is freaking astounding.
My 710 has poor battery life, if I had waited and preordered etc to get a 920, I'd be pissed.
Snow, you tried any sync adjustments?
