I have two apps on my phone that have caused a drain: GMaps and Whatsapp. I really need both as I can't live without Google Maps and Whatsapp is the number one mobile communication method in my country. After many tests I found out that disabling the compass in GMaps stopped the drain caused by it and that using Stop The Music after exiting Whatsapp stopped that drain.
I don't know what the compass has to do with GMaps draining the battery when I have the background task disabled in settings and the live tile and latitude disabled in the app, but it works for me. I just noticed that GMaps would always say that I have to recalibrate my compass when I started the app, so maybe it starts a process waiting for the compass to be recalibrated, I really don't know. With Whatsapp the drain is much clearer. They stream a sound via the music API so that WIFI doesn't turn itself off when you put the phone in standby, so it's logical that it drains the battery. Stop The Music kills the stream and therefore the drain will stop.
But like said before, it almost looks like everyone has a battery drain with a different app, so it's definitely an OS problem which Microsoft needs to fix asap.

Since I've gotten my lumia 920 and experiencing heat/crazy battery drain I said to my self that it has to be a bug. A process is stuck that is jamming the CPU and causing the battery to drain.
Part of me wants to send back my lumia and get a replacement. The other part of me wants to keep it and wait for a software/firmware update. I'm torn right now and don't know what to do. I have about 24hrs to make a decision :(
I get no other issues with my phone. Would hate to get a replacement and suffer from other problems like the proximity sensor/vibrate rattle/dust under FFC/poor build design etc.
If Microsoft/nokia would say something. At least that an update is coming soon. I would wait :(

I have excellent battery performance (2 days on a single charge with light usage), however, I have found if I accidentally leave certain apps running it can kill my battery. Dungeon Stalker for one killed my battery in less than 2 hours (not that it's a bad game, I love it and have the paid version). I don't have it enabled for background but regardless it kills my battery.

i totally agree on that. i dont use GMaps but i use whatsapp. i can feel the phone gets hot like within 5 mins of whatsapping. use the camera for more than 3 mins you can start feeling the heat. using twitter and opening random links from the twitter posts also makes the phone hot. playing a pretty basic game like wordament also heats up the phone and drains the battery.
Did anyone tried to use the phone setting the "higher connection speed to 3G" under the Settings-->Mobile network? if so.. what noticeable changes you found on the overheating issues? May be i will try using the phone under 3G settings for a day and see what i can find.
As of now to me these are the serious OS issues that microsoft needs to address asap to make customers not regret their decision to get an windows phone.

Stop the Music! | Windows Phone Apps & games Store (Nederland) Just download the trail, it's fully functional. Pin the Stop The Music button from within the app to your start screen (that will stop the music immediately without entering the app itself)

Not sure if my battery life has been "fixed"
I've had it idle for an hour and it's still at 100%. I had the network on 2g, bt off, nfc off, wireless off, no backround tasks except extras and info and screen brightness was set to low.
Have a look at my sky drive folder with a couple shots.
Now the first one shows the 100% after an hour. If you look at the other three.. Look at the time stamps in the top right hand corner. And look at how the battery is draining. This is also being idle. In addition, it is in airplane mode, so cellular data is switched off.
Edit. Before I posted this up, I put on my wifi and checked 2 facebook notifications. Battery dropped to 99%
The time in the 100% shot is 1:57. It's 2:13 now and i'm down to 98%. This was witth the phone being idle, but wifi was on. I just switched off wifi and will continue to monitor.
Man. This is annoying..

That's really crazy. I charged my phone 2 hours before going to bed last night, I didn't use the phone from then till I woke up (it was connected with 2G and WIFI, but nobody called or Whatsapped me and I didn't browse the internet) and when I woke up it was still at 100%... 12 hours later!! I've had this happen before and in the end I didn't get more than 2 days of usage. The battery saver information is just nuts and you can't trust it a bit.

Totally agree. That's what I have been doing. I think it's an OS issue. there are some apps causing it...but in general, it's the way the OS is handling the opening & closing of apps I think. On my 900 overall the battery was an issue, but I never had to rest the phone or had any freeze issues. WIth WP8 it's very different or the 920 manufacturing is an issue.

I was getting amazing battery life before the update. I think it could be gMaps causing my battery drain. I opened gMaps 4 hours ago and my phone has drained to 56% with very little usage. Rebooted my phone 30 minutes ago and the percentage hasn't moved. I use gMaps for Google Latitude, just to see where my friends are. Hopefully a real Google Latitude client will be coming soon.

So here's something I was surprised by. Shut down my phone for 30 minutes with 43% battery juice left. When I turned it on, it increased to 53%! Going to settings -> battery reveals the screenshot below:
I've just unplugged the charger 35 minutes ago and yet it is saying otherwise. This is a huge WP8 bug.

I purposely charged my phone 100% and let it sit all night while i slept.
After 6 hours, it was 75% without no use at all. After checking people hub some and went back to sleep, after 2 hours, it was 53%. Im in afternoon and have to recharge again.
I saw something about alpha jax, i had a 920 phone that had no battery drain and I had alphajax installed and running 2 games at the same time with notifications, so i'd say it is not alphajax.

I haven't read through all of the posts yet, but I wanted to share what happened with my phone.
I think you're on to something with it being the GPS. I changed WeatherFlow from using Location to using a specific city, and MyBattery app is showing 2 Days, 2 hours, 36 minutes of runtime left at 82%. Since I made the change approximately 5 hours ago, I have only lost 4% battery. Previously, I would lose 10% an hour, and considering I had WeatherFlow set to update hourly, it would make sense why I had such a battery drain. Friday between 9:30 and 4:30, I went from 100% charge to critical (5%), and that time includes when the battery saver kicked in from 20% to 5%.
Thanks for the heads up on the GPS.

My battery life has been really bad the past few days, and I haven't been doing anything different, which I find a bit off. The other night, I forgot to put it on the charger, but it was at 70% - should last through the night without any issue. It didn't, it burned down fast and died. Since then I've seen pretty crazy burn rates...no good. Making me yearn for the 8x...
