    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.
    Are you using Cortana/Location services?

    I disconnected her this morning, though mostly because I decided I prefer a standard Bing page. I had detect-tracking and run-in-background off anyway. She's cute and will connect her as needed. I do have system location services checked on, but I screen and monitor apps. I don't have them on for weather, for instance.

    Hmmm ok, I was using location services with weatherflow...maybe that was an issue?

    Hey i too faced the same problem. After 8.1 Update most of our Apps requires "GPS"...so turn off your "location" Serices,Then try out.

    I lose 2% every 8 hours idle (offline mode) every night. Is it convincing?

    I am 100% convinced it is a hardware issue, and it is the luck of the draw.

    My wife and I both have a Lumia 1020 (RM-877), running 8.1. We both have HAD great battery life, even though she was on firmware 40000, and I was on 50009. I brought my phone in for repair, and they changed the phone housing to fix the problem. After receiving the phone back, I've had crap battery life, and I mean crap. I decided to do a test.

    I erased my phone completely, installed no apps, turned off all background tasks that I could. My battery just tanked, maybe lasted 5 hours. Now I thought it was because she was on older firmware, so I downgraded my firmware to match my wife's. We were running the same OS version, same Firmware (40000), and I went through her phone and my phone, and I matched each option under settings and usage, and battery saver. Everything I could think of.

    I at the time had about 65% battery, while she has 85%. We went out, and by the time 3 hours went by, I had 5% battery, and she had 65%.

    She had Cortana enabled, and so did I. She had a tonne of apps, and I didn't. I didn't have Here Drive+, I didn't have Facebook, I didn't have twitter, nothing. She had facebook, instagram, 3 email accounts, BBM, Nokia Glace, High Sensitivity Screen, I only had my outlook account email logged in.

    So there you go, my conclusion is it's a hardware issue, and it's the case housing. I think the battery may be electrically shorting with the case housing, and it's draining the battery.

    Got a 1020 yesterday. Apart from the out-of-box battery life(lost 50% in one night), I love the phone and the camera.

    Restarted it this morning, with battery going from 46% to 34%. Did it once again and went to 37%, so could be early software calibration. If battery life gets decent enough to go for a full day without a half discharge at night, this is by far the best phone I've ever had.

    ya dont worry about that inconsistency so early on, your device needs to optimize with the software over the next 2 weeks or so. I think most of us here have had the phone for a few months at least. Keep an eye on the usage and report back later.

    On topic: My phone has been 'OK' for the last week, battery can go 24 hrs if mostly in idle. Whats interesting is I was at the baseball game last Friday, took off the charge at 5pm...headed down to game. Took a TON of pictures, browsed the web and texted a few people...i got home at 1am with 86% remaining! Very impressed. But then days passed and doing less tasks the battery drained faster.

    It may be HW related but i doubt it, theres too much inconsistency for me to believe its hw specific. I still believe it can be related to poor signaling and OS process hogging when in use.

    Have a feeling 95% of cases is software-related. The 1520 I had before had the same problem after going to wp 8.1. Intensive tasks, such as picture taking and games/videos basically took the same amount of battery juice, but leaving it overnight after updating and generally idle battery use was awful. Something in 8.1 is messing with the battery.

    Tried turning on airplane mode, with the result of going from 86% to 84% during the night. Turned off airplane mode this morning, and in the span of 2 hours, it went down around 10-12%. Could be something hogging the wifi/4g/location connection.

    Today was speaking to a bunch of t05ser5 (a bank) and the call took an hour. i was using loudspeaker as it was soooo boring listening to their crepe. the whole time the phone was on charge and yet the call took battery from 100% to 25% !!

    I can confirm that disabling location services improves
    battery a lot in our 1020. I guess that needs to be explained.

    Many users don't/won't take the time, or seek to learn their phones, particularly how their apps and settings (when provided) work. On topic, many download apps quite indiscriminately, including not checking for active access rights they grant apps, and battery-draining "features" in particular --some of which serve primarily the developer.

    I too have problems...33% over the night with merely no background apps active.
    I'm on 5009 too. Something in 8.1 is causing this as when I've had 8.0 I could get less than 10% loss overnight with much more apps in background

    Those "features" are mostly unique to Windows Phone. On an iPhone or modern Android it's not necessary to micro manage settings. Turning off location services, background services, and NFC (Android) will only marginally help battery life, if it's even noticeable. WP is still "under construction."

    True, but that's not what I'm talking about. I'm referring to micro managing settings to increase battery life. Turning off things like background tasks, location services, and NFC will scarcely make a difference in battery life on an iPhone or high end Android. WP has some serious battery drain bugs.

    We all use our devices differently, travel diversely, and live -and move about- in such different locales relative to towers, Wi-Fi, etc., that comparisons across users are SO limited. I don't have any battery problems on my 1020; mine lasts all day and evening on normal-for-me-only days, and I noted slight improvement, if anything, when I updated to Cyan 8.1. Honest. Best battery life I've had on a smartphone, going back to the original -a Treo 270, and I use this more than any prior one primarily because the camera and tethering work so well and reliably. If it was the OS, all our WP batteries would "drain heavily" -or not.

    There are various answers to why a 1020 battery may be poor. I would know because I've have 5 different ones. But before I do that, I'll share with you what I have set on my 1020 and why my battery life is just fine.

    I have 2 emails set to always sync.
    I have my brightness set to medium auto.
    ALL (yes ALL) my background tasks are RUNNING
    These include: 6snap, Bing News, Bing Sports, Bing Weather, Facebook, Metrotube, Timer, Twitter, WPCentral, and Here Drive+
    I'm a medium usage user but I get a day and 10 hours of battery life easily. I have Bluetooth and Cellular Data always on.
    I'm typically on my phone once or twice every 30 minutes doing various things with Bing Sports, twitter, 6tag, or 6Snap.
    I text about 150+ times a day and receive about 10-20 emails a day.

    Here are the various reasons and my support behind them:

    1. Poor cellular signal - I have poor signal at my girlfriend's house and I get my battery life cut about a third of what it normally is.
    2. NFC is on
    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.
    4. WiFi has poor signal or is slow, therefore working the CPU harder and draining the battery when surfing the internet.
    5. Pictures with Flash - the Flash drains the battery, if you can, take picture without it. I can get just as good picture if not better without any flash. Always test without flash before flash. You'll save battery if you try this.
    6. No closing Apps - Now that we can close apps with the "X", it is recommended to do so. I've noticed over the last week, my battery has improved by closing apps instead of hitting the back arrow.
    7. Touch - Turn touch sensitivity down to normal is you aren't using gloves and also turn off double tap to wake up. By having Double Tap on, the phone is constant monitoring the screen. It's almost like the screen is always on because the phone is always waiting for the touch. Plus, if high sensitivity is on with double tap, then your phone has a chance to open and **** dial someone. Also, draining the battery. (Happened to me when I tested it)

    These are just some things that I've noticed and experimented with that made my battery better or worse.

    After 16 hours, I have 70% battery left right now. I've texted 75+ times, listened to 2 hours of music from the phone speaker and over my bluetooth speaker, I've used all my social media apps, and I've sent out 10+ emails while receiving roughly 15-20. I downloaded 2 apps, used bing weather, sports, and news as well for about 30-45 minutes.

    I really recommend screen shotting all your apps on your phone, then doing a hard reset WITHOUT restoring from the previous back up. Then starting over if you're having problems. Go through my various steps or scenarios to see which could be the problem for you and try fixing them. If you have any problems along the way, let me know, I'd be more than willing to help!
    Dude that awesome battery life with so many running in background. But you are right, you can disable notifications on apps you do not like to disturb you but leaving the background access opened. I will surely try this as my battery life is not good on my 1020, and imagine my email accounts do not even sync as arriving, one is once a day the other is manual.

    Hello guys! My daughter asked me to buy her a Lumia Phone because of the camera. I got her an used red Lumia 920 in excellent condition. I'm an android user and my daughter is an iPhone user. My first impression of the phone was that it looks great but after seen that after so many years Windows Phone has not been able to manage at least having the most popular apps and the ones available are very faulty, they lost my respect.
    I also bought a Lumia 1020 to test it and see what could be done to improve. I'm just starting to play with it but my main claim is the low battery life and the poor app choices. I could life with the limitation of apps but cant with the faulty ones.

    Hello, I'm having a same battery drain issue with my 1020. It was 17.7% / hour after hard resetting - and also adjusted settings. Yesterday I installed Battery Doctor and charged 1020, I found a funny thing. Although charging process finished, the animation in the app was still saying "Charging" even though its "tickled" process was done. I let it get charged further a couple of hours, then it lasted long, and usage rate dropped to around 10%.

    The battery became flat before this morning even though I set to flight mode. I'm charging it now and would let it get charged further a couple of hours to see how it goes. I deleted My Radio, Facebook as well, and haven't installed much apps at the moment. I have one Exchange email account being active.

    "Calibration" method didn't work for me as when it's dead, it couldn't turn on (just showed red battery and it went dead again, not coming back to turn on).

    Just an update - after charge, currently discharging rate is 8%~10% and my setting is:

    SIM : 3G, Carrier: Vodafone
    Bluetooth, Location, NFC, : off
    Battery saver: off
    Brightness: Low
    Screen rotation: locked, portrait
    Backup: apps+settings, text messages - on, photos+videos - off
    Touch sensitivity: normal
    Glance screen: off

    I have one Exchange account which is set to use "Download new content - as items arrive" - just to see how much overall battery drain is going to be. I uninstalled FB, Radio app, health, food. So not much apps are going on. (By doing this test I'm little bit disappointed that I have to consider about battery drain issue when 1020 is supposed to be a smartphone to do many things....)

    In my case i found the solution! I was having 8% /hour in airplane mode.
    I tried everything and one simple thing fix the problem, from 15% to 1% /hour turning off location.
