    I have honestly had enough Windows Phones (went through 3 or 4 920 and 2 1020s) to determine that the battery life issue is not a faulty hardware issue. Here's a compilation of things I've noticed, or tried on the web that appear to be true:

    1. Background Tasks
    From what I can tell, there is definitely a bug with how background tasks are handled. If you have even 1 application permitted to run in the background, no matter what it is (even just a battery app!), you will often (and likely inconsistently) lose up to half of your battery life (likely 25%). From what developers have told me, background agents might get stuck in the background pretty easily.

    2. Installed apps
    If you have installed a lot of apps that you do not use on a daily basis, you will find that you have significantly poorer battery life. Windows Phone appears to allow apps to run in the background immediately after they are installed or updated until you open the program, then go back to background tasks and explicitly block it. Generally speaking, if you don't use the app, uninstall it. Every week or so, you should also go down your list of apps and make sure you have opened each one at least once (since installation or upgrade). Ensure inside each app that you turn off Live Tile updating (if not needed) and disable any background tasks internally. Then check your list of background tasks in settings and ensure that they are all blocked (see point 1).

    3. Turn off wireless services when not in use, or in low signal
    GPS, WiFi, Bluetooth, NFC, and even 3G/4G data. If you aren't using it, turn it off. The important thing to remember is that it may not be in use, but the device is still trying to use it. It's searching for WiFi networks, searching for Bluetooth devices, trying to connect to an NFC device, etc. Additionally, if you are in a poor reception area for any of these services, battery will plummet. This seems especially true for LTE and cellular services. Starting with the Nokia 808, any Nokia device I've owned seems to have terrible battery life in low cell reception areas. This applies to WiFi and Bluetooth as well, so if you know you are far from the base, shut it off and use something closer if possible.

    4. Always close apps
    It seems odd that if you disable background tasks, then navigate away without backing out that a program might continue to use battery. However, this appears to be the case. If you leave a program running and just turn off the screen, battery will suffer. This seems especially true with apps such as Nokia Camera, Nokia Drive, Baconit, Readit, and a few other normally CPU intensive programs.

    5. Battery save mode
    Definitely leave it set to "When battery is low," which will automatically block anything from running in the background, limit syncing, dim brightness, and likely a bit more when your battery is below 20%. This is very helpful and highly recommended. Also, as a last resort, if you are noticing a rapid decline in battery and don't need up to the minute email notification, switch it to always on.

    6. Glance, Double tap to wake, high sensitivity
    Those nice little features of Nokia phones are great and all, and each one may only use a few milliamps, or even a few fractions of a milliamp per hour, but that all adds up. Disable these when you're trying to squeeze out every last bit of battery.
    (note: there are likely equivalent, and similar tips for other manufacturers, but I have only used Nokia)

    7. Xbox Game synchronization.
    I don't know how many people are that into mobile games, but if you can, turn off all of the options in xbox games settings to disable the highly battery intensive syncing of your game information.

    8. Email accounts and other syncing
    Be very mindful of how many accounts you link to your device. It's nice to get all your email accounts on your phone, but if you really don't need to respond from that address, just forward it to one account and link only that account to your phone. I have only my Live account on my phone, and all of my other emails accounts forward to that account. I get all of my mail on my phone, and my device only has to sync one account (and as items arrive). If you have to have other accounts on your phone to send from, consider adding them as manual sync only, forward to your one account, then send from that email when you have to. Might be a little annoying to switch back and forth, but syncing definitely uses a lot of power. This also applies to Facebook accounts, Twitter, and anything else that needs to stay up to date. Remove them, or limit how often they sync to save battery.

    9. Be mindful of your usage
    If you let your phone sit idle and you're only dropping 1 percent an hour or less, chances are, there's absolutely nothing wrong with your device. If that changes rapidly on days that you use it, then you just use it a lot. Keep in mind that if you browse the internet a lot, keep checking your email, read reddit (big usage for a lot of WP users!), and especially play games or stream media, you will suck your battery dry. If you do any of these for about an hour, it will likely cost up to 25% of your battery (sometimes more with some games).
    Generally speaking, if the screen is on constantly, you'll likely get between 5 and 10 hours, depending heavily on what you're doing. If you're playing a heavy 3D game continuously, it could be even less.

    These are just some random tips that I've found. Some of them are very unfortunate, but it's really not better on Android. iOS I am uncertain about. Also, your mileage may, and will vary, mostly dependent on what apps you have installed, and how you apply the tips I mentioned. Following these tips, on my usage, I can easily get 15 hours. My usage is Reddit heavy, sms heavy, and usually includes a good amount of web browsing, and a call here and there.


    EDIT: Grammar/spelling/added a couple things.

    've done two tests on my 64GB 1020, with the first load up to 100% before bed, put on airplane mode and disconnect the charger, and the next morning it dawned with 100% battery. On the second night I repeated the test, only left with data and wifi connected (plugged into my home network) and all applications that currently use Sundo running on battery back-up and the sun rose 100%. Only during the day I think the consumption is very high. I have whatsapp, an email every 2 hours, a few hits to FB, 1:30 twiter and songs divided into 3 intervals of 30 min. With all this step not 12 hours after taking the decision. Is this normal? My reference is my last phone, N9 with a few more thing that connected a battery and 2 years of daily and lower than the 1020 refills, and lasted the same thing.

    You can either use linking by logging in at outlook.com and configuring the account to sync your other accounts, or by logging into your other account and looking for options to forward mail. For example, in GMail, there is a specific setting to forward mail to other accounts. Yahoo and AOL mail have similar settings. Most mail providers have options to forward all mail.

    Don't expect such good battery life on 1020, it's 2-3 times worse.
    Also it's very unstable, reboots, Bluetooth is crappy.
    It sounds like you got a faulty phone. I get up every morning at 5am and spend over an hour at the gym while streaming Nokia music over Bluetooth on my jaybird xbuds. My battery lasts all day, and I'm a heavy user.
    The Bluetooth sounds great in my car and on my jaybird xbuds. I love this phone.

    Another question is regarding my shipment. With the unit in standby, how long it takes to load the L1020 you?

    My experience was horrible. I live in Sweden aswell and bought it a few months ago.

    Long story short, battery life was really bad. Ended up returning it.

    My symptoms:
    5+% battery drain/hour on idle with everything off. Even no sim-card in and flight mode activated.
    10-20+% battery drain/hour on load.

    I tried giving it several weeks of charging etc, nothing helped.

    Can someone please explain why at the end of my lunch break, even after disconnecting all APPs, my battery continued to have a high consumption even in standby. Stopped only after a reboot.

    first month or so very bad battery life.
    Suddenly it started to go up and now it says 1 day 5 hours on full charge (with no use).
    Current discharge is 2,93%

    When not used for longer period it goes down to somewhere 1%, but it could get up to 20% an hour.
    Since a reset of my battery-app data, it has an average discharge of 4,88%

    Another update here. After sending my phone for repair and not seeing any improvements, Nokia sent me a replacement phone. The replacement 1020 is perfect! All my settings and apps are the same as before: wifi, glance, double tap, 4g data, bluetooth and nfc are all on. Xbox games, location and music services are off. I have skype and whatsapp installed, plus a weather app in the background and one email account syncing every hour. The battery drain is less that 1% an hour when in standby (only drained 4% over night). The drain rises up to 4% an hour when the screen is on for a prolonged time and I use the device heavily. It's now 7 hours since my last charge, the battery is at 93% and showing 4 days and 9 hours remaining. With moderate use I can easily go 2 days on a single charge. This proves my suspicion that my first 1020 was defective and I suspect that many of the people complaining about poor battery life have defective units as well.

    Can you report back after a couple of days? I have experienced very similar results, but after a couple days realized I was wrong. Also, can you go to Settings -> About -> More Info and posts the following:

    OS version
    Firmware version
    Hardware version
    Radio software version
    Chip SOC version


    Thanks!

    It s very awsome. I really want one like u. My 1020 turn on wifi, gps, glance, x2 tab, 3g data, sync facebook, viber, mail. But i turn off bluetooth and nfc (rarely use them). When standby it drain appropriately 3-4% per hour. Is it normal?

    You have a newer Firmware and Radio version than I do (AT&T USA), what country/carrier variant do you have? Also, you said you have the old one still? Would you be able to post the same numbers from that one and see if they match?

    My Firmware is 3045.0000.1325.0001 and Radio is 3.2.04025.1. Considering one of the biggest issues I've noticed is bad battery on low signal, I would bet that you may have better battery due to updated radio software.

    Interesting...I have the Canadian pentaband Rogers version. I'll check the numbers from my old 1020 once I'm home and will update you.

    So I checked my old phone and it has the exact same OS, firmware and radio versions as my replacement 1020. Also, Windows Phone is really terrible at predicting remaining battery life ... the 4 + days remaining I noted earlier was way off. 15 hours after charging and with light use, my battery is at 70% with a day and 10 hours left. Not bad by any means, but I will keep an eye on the performance and post an update in a week.

    This sounds more like what I get, depending on usage. Hopefully the Black update fixes some of this at least, and if not, hopefully WP8.1 does. But definitely hoping for a sooner-rather-than-later release date!

    So its been a week and my replacement 1020 is still performing really well. I get just under 2 days of moderate use on a single charge.

    My settings are as follows:
    Data on (don't have LTE so 3/4G max), wifi on, bluetooth on, glance on, double tap to wake on. Location is on when needed, Xbox game and music services are off.
    I have lots of apps installed (Whatsapp, Skype, Amazing Weather, TuneIn, AudioCloud, MetroTube...list goes on). Only Amazing Weather is allowed to run in the background. Even though Whatsapp is blocked I still get messages though. I also have one email account syncing every hour. Overnight, my phone drains 1-4 % (I sleep for 7 hours).

    My typical daily usage involves an average of 4 calls (3-5 minutes each), 10 texts, 50 Whatsapp messages (includes some image/voice messages), 40 minutes of streaming music, 1 hour of locally stored music, 1-3 YouTube videos, 1-2 app downloads, 2 Skype calls, capturing 5 images with the camera, reading 30 emails, writing 3-5 emails, 30 minutes of web browsing, some bluetooth transfers with my laptop.

    In the past week, I did not manage to drain my battery to 0 . The lowest it reached after a day of really heavy use was 25%. Usually, my phone is around 60% at the end of the day. I can say that I am very satisfied with the performance of my 1020, it has the best battery performance of any smartphone I've handled. I take care of the company phones at my work, and the HTC One, Samsung S3, BB Z10, BB Z30 and iPhone 5 do not last more than 10-14 hours with moderate use. I hope everyone else manages to find a solution to their battery problems, as the 1020 can really be enjoyable when its not switched off.
