aye, with that in mind I wouldnt mind carrying a spare battery, but where does it go..hmmm, a solution might be to make jean pockets wireless chargers, charged by walking action hehehe
It?s just an analogy with your house wiring. Your house may have 42 circuits of 15 Amp each, but it does not mean you can use all of them to capacity. You will exceed your panel capacity with few circuits only.I wanted to test this...im sitting here at 11am..all lights are on, every gadget and device is on, ive hooked up my exercise bike with a dynamo feeding extra into the mains...i am getting tired...
Are you in the USA on AT&T? I've read some stuff indicating that there is something about AT&T's implementation of LTE that can negatively impact battery life. Whether or not that's true, I have no idea. I do know that when I spent a couple weeks over Christmas in an LTE area, I was surprised at the impact it had upon battery life. It literally felt like there was something sucking the juice out of it, particularly if I was actually using my phone. But the drain was also rather dramatic when I wasn't doing anything with the phone. Under normal use in a non-LTE area, I can probably get two days out of a charge.

Same with your phone, just because Nokia gives you every feature there is, it does not mean you can run all of them without affecting the battery life.
Once you grasp the concept, do some power management rather than complaining here because I don’t think it’s going to solve anything.

I have been using Lumia 920 since one month..
Heating is there but battery life is around 10-12 hrs
I have heavy 3G usage...some gaming and music..
I keep my NFC disabled, Nokia drive is off and switch off wifi when not in use..
Any smartphone with such a high resolution screen, live tiles, always on WiFi...should have rapid battery drain
This should definitely improve with future updates...I feel being patient and judicious use of your device will help..
Well it has been over 24hrs. since I did this procedure. My battery usage is still low. I got 22hrs. of uptime on the same charge yesterday, using the phone moderately, push email for two accounts and a couple of long phone calls. Battery Sense was reporting -2.2% drop most of the day. Battery drain went up a bit on the evening to -4% playing games. The most important thing I noticed though was the phone was no longer staying warm when idle, an indication of high current usage.With a lot of frustration, I have been experiencing high battery drain also, with the phone staying warm even while idle.
Following various comments, fixes, could be' on various forums, I hard reset my new, less than one week old, phone.
I was kind of annoyed, surprised it took a very long time to recover, with a picture of gears churning on the screen.
Finally it booted up with a message, reset or restore. Wasn't expecting the choice. I chose restore to see what's up.
There was an amazing amount of stuff to restore.
After restore completed, my phone was still having battery drain issues. I decided to check out what this back up and restore thing was.
Pardon me I never read the manual. No need to go into discussion of the process.
I then chose to disable back up and restore, soft reset, and boom. Battery usage is now at -2%/hr. instead of -12-20% idle.
Have any of you tried this?

Not true. My Lumia will get scorching hot and burn through its battery in 4-5 hours. My iPhone will last 12-18 hours. There's a bug in either the OS or the firmware that causes Lumias (maybe other WP8 too, not sure) to spin out of control and run at 100% for unknown reasons. This isn't just a settings issue.
Does iPhone have:
live tiles? NO. really do not think the live tiles a causing any battery drain.
NFC? NO.
4G? only one model has it. No 4G here in Thailand so I can not blame 4G but on 3G the batter life is no better.
so it isn't a fair comparison at all.
even microsoft and nokia says to turn off unneeded background apps.
do you actually use NFC regularly? if not, it should be turned off obviously.
also, always on wifi is available with lastest Portico update. if you're not updated, it's your carrier's fault. I do not have this update, my phone was brought outright so no its not the carriers fault everywhere I blame Microsoft and Nokia for not releasing this update to all unlocked phones at the same time.

I have no background tasks running... Backup Off. I close tabs on exit from IE...
I've made some headway at last. I've just hit 24hr's since the last charge and have 62% battery remaining. That's 2 hours streaming music on the tram (headphones), just over 2hrs voice calls, a dozen texts, 3 email accounts sync when arrive (22 emails total around 12mb), just over an hour with Proshot, perhaps half an hour with Pictomaphone, photo sync with skydrive, time browsing photo's on the phone, and maybe nearly an hour's light browsing on Internet Explorer. Not intensive use by any means, a quiet couple of days as work goes, but it's a marked improvement regardless.
I have no background tasks running, Wifi On, Bluetooth Off, Tap + Send Off, EE network (3G), Backup Off. I close tabs on exit from IE. I have Drive beta uninstalled and Skype is installed.
I've had the phone for 2 weeks, and it's been draining very quickly. The only thing I've changed in the last 24 hours is my constant fiddling with the tiles. After I finally settled on a tile arrangement I really like yesterday morning (while on charge), I did a soft reset. Haven't touched the tiles since (apart from to open applications) and here I am, 24hrs later, apparently over 24hrs remaining. I don't know if that's what's helped the battery, but I haven't changed anything else. Perhaps the indicator is out of sync with the battery and will turn off any minute? I'm suspicious and paranoid. I'll post back if that happens.
I will give this a try today and see if it makes a difference to my phone.With a lot of frustration, I have been experiencing high battery drain also, with the phone staying warm even while idle.

Have any of you made any progress with this?
After the Hard Reset, disable back up, restore, my battery life seems to b stabilized. Most importantly, the constantly device warm issue is gone. Touching the back of the phone and feeling cool gives me assurance the device is not running amok..
I tried posting earlier, was distracted by work.
Previously, my phone, according to Battery Sense, was consuming between -22% to -11% per hour idle. After the applied procedure, power consumption has been at a high of -11% per hour to as low as -1.1% per hour, with the average being around -2% per hour with use.
I am thinking Back up, Restore is the culprit. I does not show up in your idle process and is configured on by default.
