    I bought another battery from a different seller, but it shows exactly same life as 7 hours of others.
    I strongly recommend to call Nokia Care to exchange your phone if you have battery drainage problem.

    whats weird is that on the 1020 im using (not updated to wp8.1 yet) is that my battery lost its last 18 % charge in a half hour of using office lens but as soon as i connected it to charger, it went back up to 27% and has stayed around that way 10 minutes after immediately unplugging the phone. any ideas?

    I updated my wife's phone to 8.1 and it started draining battery fast. I tried a lot of fixes including disabling background tasks, wifi sense off, etc. Eventually, I went into every single setting and found that the "double-tap to open" option is somehow enabled; I unchecked that. I also found that Glance had been updated and was requiring a restart (even though I have rebooted the phone many times before). The battery consumption seemed to have returned to normal. However, 6tag/Instagram still eats battery based on the stats from battery saver. But at least I know where the battery is going. YMMV

    Excellent summary matthoms! I can definitely confirm though that low reception (be it cellular, wifi, bluetooth, or anything wireless) will kill my battery.

    I just want to give a little insight into this:
    3. (THEORY)Background tasks are disabled making them constantly try to run but are stopped over and over again, therefore draining the battery. - My battery life has improved since I turned all my tasks on instead of being off.
    I thought the same thing for a while, and I think it may have actually worked that way at a time, according to what they have been saying about background apps, your theory _should_ not be true. Here's why (excuse me for not finding my sources on this, but I'm mostly compiling what I've learned about how the OS works, how it appears to work on my phone, and from speaking with developers):
    When you install an app (some apps this happens only when the app is launched), it requests from the OS the ability to run in the background. If the OS accepts this requests, the app will provide it with a small portion of the application (basically a small function) that will get executed periodically. This small function is limited in terms of size, execution time, and functionality. I don't know the specifics of the limits, but I know it must be very small and only has something like 25 seconds to run and complete. That means the task might get stuck in a loop or fail to connect to a server, but it will timeout and be killed rather quickly.

    When you turn off background tasks for a specific application, the OS simply won't accept the function and will not schedule it to run. So when the application is closed, it is closed.

    There are two main exception to this though (that I am aware of):
    Media - A media application will run in the background and will be able to buffer audio, change tracks, accept input from media controls, etc. I'm not sure what other background capabilities these apps have, but this does not appear to be heavily exploited except by WhatsApp (though I believe they stopped that at this point). This can, and I believe always does, override any settings that say not to run in the background.
    GPS - In order to enable navigation with the screen off, GPS applications are allowed to run continuously in the background. These are the ones that are huge risks to battery life, and this seems to be the "hack" that developers tend to use to get around background task limitations. You'll see a number of apps in the store that claim they require your location, most are for ads, but some are just to enable background privileges. This was more prominent on older released of WP, but it still exists. Prior to 8.1, apps like Waze were able to override being disabled in background tasks. 8.1 seems to have blocked this.

    What this means is that the "blocking" only really occurs when you run the app. Every time you run an app that wants to be allowed to run in the background, it'll send that request to the OS. The OS will say no, and the app should be done with it. Unfortunately, it may not always work that way. The app may get told no and keep trying. That will use more CPU to keep looping this unnecessary command. But if you're seeing an increase in battery life with apps allowed vs blocked, that's why: poorly coded apps.

    On the contrary, if you have several (well-coded) apps set to run in the background that you don't need, they'll still try to run every time the OS has that app scheduled. That means that, for example, every 30 minutes, you'll have the phone wake up (without turning on the screen) to say "hey guys, time to get up! You have 25 seconds to do what you want!" and the apps just all press the snooze button. Unfortunately, each app has to do this. So while it may be .001s each, if you have 10 apps, that's now 0.01s total, plus OS wake up time, plus apps that actually do something, plus poorly coded apps that may take the whole 25 seconds for no reason.

    My opinion: disable apps you don't want running. Let the OS handle it. If it's doing something wrong, you know where the problem is: Microsoft. Then you can file bug reports directly to them because they aren't handling background tasks properly.

    Disclaimer: Based mostly on what I've heard/read/seen/tried. No claims of accuracy. Please correct me where I am wrong!

    EDIT: Just re-read the API doc for background agents and updated my post. It's 25 seconds that most apps will have to run in the background. Apparently there's a "Resource intensive" background agent that can take up to 10 minutes, but those will not run unless the device is plugged in and charged > 90%.

    "double-tap to open"
    Hey, a couple of days ago I enabled that function and its been now 3 times when I noticed my L1020 being pretty hot! (and draining almost 30% per hour! So yeah, i turned that double tap off, lets see if that was the problem! I have a flip cover case with a little magnetic strap, i guess that could be interfering?

    My Lumia 1020, today (1 hour of music, 15 minutes of call, 3G on, WiFi off, Bluetooth of, location on, glance on, facebook and messanger also installed, and everything allowed on background) from 3:45 to 15:55 it used only 3%. At 16:00 I have started to browse internet now is 16:40 battery is 71%. I forgot to say Tha I am on 8.1 preview, hard reseted after. No installed battery monitor app that sucks battery. I think the display is extremely hungry. Also plaing games like angry b. epic uses extremely. Brightness is on minimum.

    I guess I have to count myself lucky... I installed 8.1 preview the day after I received the phone, so I dont have any real experience from when it was on 8.0. But I am very happy with my battery life. I use my phone all day, texting, emails, taking pictures, listening to music, etc. And by the time I get home after 12 hours I still have well more than 50% of the batter life left. I charge it wirelessly every night, and its good for another 12 hours of moderate to heavy use.
    Previously I had a 925 and I would be lucky to have 20% at the end of the same work day.

    I think if the phone has to switch a lot between 3g/2g/lte it drains battery. Some games I have had was using background battery in statistics same amount they used when active.

    I'm very satisfied with my 1020 battery. Battery life is so essential, and it took a while for me to decide on my first smartphone without a replaceable battery. The 1020 battery doesn't last as long as the remarkable one on the 1520, but it is still excellent even on heavier phone, browsing, and photo days. I routinely plug the phone in at night; but, often I forget or can't, and I still can get in a second lighter-use day. (I'm running 8.0, patiently awaiting any auto updates.)

    Every now and then when this site tells me about the new apps I may be interested in, I download it. I since noticed the battery drain.

    I have just removed some apps and like that I have already seen a difference.

    - Bet365
    - Nokia Refocus
    - Istagraph
    - Nokia Video Trimmer
    - Groupon
    - Nokia Glam Me
    - Where's Timmy
    - BitTorrent Remote
    - GasBuddy
    - Movie Moments
    - Slowly
    - TimmyMe
    - Torrex Pro
    - Angry Birds Epic
    - okcupid lite
    - Gotya
    - Translator One
    - Mirror Cam
    - Hotel Tonight
    - Meme Maker
    - Tinder for Windows

    I know its a lot but there is a bug app in that list

    I hope this helps guys

    I have a 720 before I got my 1020 and I can say battery life is really a little disappointing. My 720 can last up to 3-4 days with occasional gaming and browsing. I have to charge my 1020 everyday and it gets really hot sometimes on standby. I came across this app Battery Doctor which you may want to try because it can show you apps that uses battery the most. In my case, the culprit is the airplane mode and battery saver turned on.

    My lumia 1020 battery's draining so heavily ( 94% - 8 hrs remaining ) i tried doing the soft reset, disabled all the background apps, turned off the settings, at last even did a hard reset and installed all the apps again and after two days it still on to the same issue...
    Anyone facing the same issues ?
    Well I have a suggestion for you. Don't use your 1020 as a main phone switch the simcard in any other device for 3 to 5 days. And charge your 1020 to 100% and leave it in drawer with wifi on . repeat this procedure for a week. Actually once your lumia device became habbitual of showing 16 or so on hours remaining after 100% charge. It will show same till ita death. Only you have to change its routine so it can calculate new battery life cycle. I sold my 1020 but when I was fed up with battery life I swapped the sim card to 808 and let the 1020 die in drawer. It lasts upto 5 days ๐Ÿ˜„๐Ÿ˜„ with one charge ..

    I have the same problem. I only have the apps that are related to maps and the camera installed. Nothing else. The battery life was about a day before I installed the upgrade 8.1. Now the battery life is 4 hours even if I don't touch the phone. What changed? All the apps are the same, I use it even less, turned on battery saver mode for the whole time, wifi and everything else is turned off, still the phone won't last for more than 4 hours. I loved this phone till now, but now I'm starting to lose faith. I even tried resetting the phone, no apps installed. And it just won't help. Do you have any other ideas I could try?

    yep, battery is ****e.
    dream back ot the days of the nok5130, with a talktime of DAYS, let alone standby of 'for ever'.
    this is why nokia had to sell out to 'the devil' !

    1. i carry a battery pack to recharge,
    2. also tyr running with battery saver on, as that really dents power consumption
    3. keep blue tooth off unless actually using it


    but why should u have to dance around, the spec is below-acceptable as of 'merchantable quality' in my view

    Same, twice a day charging...and thats on low-med use. Generally i lose about 10% over sleep (7-8 hours) which is below average in my books but acceptable, but this morning woke up to my battery at 69% from 100% (7 hour period). Wow.

    Following up, 12 days after updating to 8.1: My 1020 battery still lasts all day, even on heavier days, which for me means hours of Phone, Camera, and IE use, and not much else. You do have to learn your phone, including the effect of phone and app features you use, and then use it and compromise in line with your priorities.

    You also have to figure out when you've trashed your device, or if you purchased a bad one.
