    Anyone care to share your stats? Mine seems rather acceptable.

    If its an email syncing issue, what email provider are you using? How often do you let it sync?

    I'm seeing about 1.2 to 2% drain per hour, which I'm very happy with. I have wi-fi set to always be connected, LTE, two email accounts (Outlook.com and Exchange Server) set to check every 15 minutes, double tap to wake, and everything else disabled. No background tasks except for Weather Wallpaper which I recently added, and it doesn't seem to cause any trouble. No apps or browser sessions left running.

    I'm currently charging the phone overnight once every 2 days. I was in the habit of leaving my phone on the charger every night but lately I've been wondering if that's bad for the long term health of the battery. I wish there was more solid information about that. In my opinion, devices should be smart enough to charge themselves in a way that is optimal for long term battery health. It doesn't sound like it's the case, though. I guess this is one of the downsides to getting a phone without a removable battery... having to worry about this. Samsung does a better job there.

    I had similar issues with my 920 (mysterious battery drain, 100%-low battry warning in less than 5 hours off the charger, back of the phone heating up substantially, even just surfing the net, etc.) and found that if I restarted the phone every 2-3 days it behaved a little better.

    Now with my 1020 I am having much much better battery life. The phone easily lasts the entire day with plenty of battery left over by the time I go to bed (5am-9:30pm, usually with 35-50% left over). This is with glance on, wifi on, blue tooth on, LTE on all day. I did go in an lock down several background tasks but that is my only concession to battery saving so far. Now having said all that, I will say that this phone also will randomly restart itself from time to time. I have seen it do it in the middle of the night on the charger (the bright screen wakes me up) or just sitting on the desk at work. I can count about 6 times so far that it has done that (that I have noticed at least), but none while I was using it so far. I think the OS does get "hung" on certain processes sometimes and needs a restart to free itself. I would also note that as a computer enthusiast, not all processors are made equal. The same processor can be made in different batches that have different characteristics. Some batches might be great for overclocking because they were actually binned for higher clocked chips but they needed more lower clocked chips, as an example. Anyway my point is that I don't know what type of "acceptability" qualcomm is using when they test batches of these ARM processors. Some may struggle slightly to maintain the required speed, while others may do so with ease.

    Just tossing my theory out there.

    Regarding manufacturing variability, that is 100% Nokia's responsibility. They should have automated tests that stress all components and ensure that every single phone coming off the line conforms to design parameters and acceptable operational limits. Phones that do not pass such tests should never end up in the hands of customers. And if Qualcomm or any other component vendor can't supply parts that are reliably verifiable with such testing, it's Nokia's responsibility to find something else that is.

    I don't know how good of a job Nokia actually does with this, but it is their responsibility. Shifting that burden onto customers would be a terrible long term mistake.

    I am not suggesting in anyway that customers should bear that burden. I am just saying that ARM processors in general are very low cost processors and I rather doubt that they would have the quality control that Intel would use to check their chips with. I am fairly sure that there are tolerances that the processors have to operate within to be deemed "ok" for use in our phones. However we do not now how tight or loose those tolerances are. One batch may be barely acceptable, but still fall within those parameters they are testing them with. Another might excell. The weaker chips might require a small voltage bump to achieve the same performance, but conversely also produce more heat as a result (again perhaps all within the testing parameters).

    It seems as though you guys are having great battery life due to now allowing background tasks. Is there a benefit to having background taks allowed or not allowed? I thought that is what effected live tiles and what not.

    Currrently I have:

    CNN
    Engadget
    Foursquare
    Locksider +
    Metrotube
    MyTube
    Simple Calendar
    Weather Flow
    WPCentral
    YouTube

    All allowed in background tasks and my battery while on low brightness lasts about 8 hours, while on high brightness lasts about 6 hours with moderate use with maybe a game or 2 of FIFA and 3 emails synced once every 30 minutes.

    Modern devices have a deep sleep state in which they consume very little power. To minimize power consumption, you want your device to spend as much of its time in that state as possible. Every background task, by definition, represents an opportunity to leave that state. Who knows what these apps are doing in their background tasks, how long their actions take, and how often they're doing it. The app developers almost never tell us, the OS doesn't tell us, so the only thing we can do is block them and guess/hope based on the resulting change in battery life. It's not a very good way of doing things in my opinion. I'm sure there are many harmless background tasks but, given the lack of information, I'd rather just block everything that isn't absolutely needed than try to figure out what is safe or suffer with poor battery life.

    I only allow apps that does meaningful things in the background, such as updating tiles that I need. :)

    Microsoft should really get developers to prompt user on the app enabling background task (like location), it gets kinda annoying having to check that once in a while.

    I too had the battery issues at the beginning...battery drain of around 40 % on one night on standby after first charge, no apps running and so on.

    but the drain started to get less worse with subsequent charges, and is now holding up fine, with an overnight drain of around 6% (glance set to peek, all background apps disabled, battery saver off), and I am getting around 25 %battery left after 12 hours of use (light surfing the web, taking maybe 10 to 15 pictures (max 2 or 3 with flash on and maybe 30 secs of video), brightness set to automatic, background apps disabled, checking emails every hour or so, and making maybe 5 to 6 calls of around 3 minutes each, texting, and of course browsing for apps for maybe 30 minutes)

    i did change the sync settings to every 15 mins for my most important mail account and to 30 minutes to an hour for the other mail accounts and this might have made the difference...but I m not sure if the battery needed a "run-in" period like motorcycles to perform optimally, although i wouldn't know why.

    Hi all, I have just got Lumia 1020 for about 5 days, my battery only last about 10-12 hours standby only
    from a fully charge about 2 hours. Try to improve the battery, I don't use and turn off to test almost
    of everything I could think of, wifi, nfc, bluetooth, double tap to wake, disable background task,
    no live tile, soft reset, hard reset, low on screen, xbox game off, xbox music video off, no vibrate,
    fight mode, power saving, etc all the stuff people suggest.
    My question, is it normal 10-12 hours standby only from a fully charge?
    Or am I still miss some setting?
    Or I got a bad battery should return the unit?
    I love the phone, quality build, great experience,
    smooth, no hang, everything great, only the battery
    Please advice me, Thanks in advance

    Make sure you don't leave any apps or browser tabs open. If you've done that, and all the steps you described, there's probably something wrong with your OS environment or hardware. You might want to also check your battery drain in airplane mode to see if the cellular radio is the cause of your battery drain.

    10-12 hours standby is definitely not normal. With light use I get over 3 days. I've attached my current battery graph (from "Battery Sense" by Vasan). This discharge cycle includes some usage every day including 4 pictures taken with Pro Cam. I have most things disabled except for double tap to wake, and screen is on auto brightness. I use Weather Wallpaper and have two email accounts set to sync every 15 minutes. I'm always signed into Skype with its live tile and notifications, plus I have a couple of other live tiles that update. Wi-fi is set to be always connected, and an LTE signal is always present. Most of the time I have a strong wi-fi signal and a weak LTE signal.

    This is not normal. What is email sync setting? I think there is a weird bug when sync setting is set to download as the message arrive. It drained my battery in 12 hrs. I then changed it to 15 mins. I got 36 hours with this setting. I then changed it again back to download as the message arrive. I don't see battery drain this time.

    I have everything on except blue tooth and i get 60 to 70 left at the end of the day. Only weather and whatsapp running in the background. I turned on Bluetooth also yesterday and last night it was 50% left at the end of the day. I was playing songs over Bluetooth in my car. Occasionally i have this heating up issue and i restart the phone. Nokia gps apps drain the battery very fast

    Hi Chocka, Thanks for the reply
    Currently it is in brand new status, only 3 people in my contact import from sim, nothing else is setup,
    all the app has not setup yet, No hotmail gmail, if I still have to disable mail sync setting, could you please guide me where should I go? And how long does it take you to 1 full charge, 2 hours for me is it normal?

    Hi TGR42, thanks for the reply
    I have tried switch to fight mode, seems no improvement on the battery,
    it still drained the battery within the same time.
    I did make sure exit out properly and disable the background task.
    If it is OS environment, what else do you think is drain the battery?
    If it is bad battery, I am going to return it tomorrow!
    Thanks for your reply again!

    Sounds like it could be some bad hardware. There is one other possibility I remembered. There's a possible bug where if you disable location services in the settings, and some app wants to use location but gets denied, it may cause excessive battery drain - even if the app is not running. For some reason practically every app wants to access your location, which is really annoying. Anyway, supposedly this can be resolved by enabling location, then entering each app that wants to use location and exiting it. In general I don't recommend disabling location because of this bug. (I originally learned of this bug from someone else on this forum and my own experience seemed to back it up, but it's a hard one to pin down so I'm not 100% sure.)

    By the way, I don't recommend disabling wi-fi unless you're going to be away from a usable wi-fi network for a long time. But if you left your phone in flight mode for at least a couple of hours and still got the excessive battery drain, that should rule out communication with the outside world as being the cause of the problem.

    If you don't have any email account setup, then it might be something else.
    I haven't timed my charging. I think it is close to 2 hrs. From what you say, it may be something is wrong with your phone. Return or exchange it while it is possible.

    I think I have tried everything I could, I just want to make sure I have done what I can do before go back to the shop.
    Going back to the shop tomorrow, hopefully they let me exchange for this issue.
    Good luck to myself. Thanks for the help!
    If I get a brand new one, any suggest for the first charge?
    Drain first then charge for 12 hours like old days?
    Or charge straight the way for 12 hours without drain the battery?
    Or drain it and charge until it shows 100%?
    Thanks again

    Charge it 100% and start using it. That is what i did. I was told that lithium ion batteries should not be drained completely very often

    I was initially having a discharge rate of anywhere between 10-20%/hr. Seriously wasn't happy so pocked around a bit and realised I don't live in a 4G area, so switched phone to 3G max. Last night battery discharged at 2%/hr so now a happy camper.
    Seems signal/reception might have a lot to do with battery life, if you can't attribute the problem to a specific app.

    Hi all,

    Got my phone last Friday and I like it but I am worried to use it as it seems to drain battery really quickly.

    Since I've got it, I have let it drain to completely dead and recharge and 2/3 more times when it was just under 10%. I did a soft reset about an hour ago.

    The problem I have is that it barely lasts a day. When it is idle, it hovers between 2-5%. The issue is whenever I do something like Internet Explorer, look at my photos or load up Whatsapp, Twitter etc - it shoots up to 15-40% drain per hour.

    This is how my phone is setup-
    - Network set to 3G
    - Brightness set to low
    - Glance is off
    - One email account set to check every 2 hours
    - Background tasks are now only Whatsapp & Battery
    - Bluetooth Off
    - Wifi On
    - Location On
    - Xbox Live Off
    - Xbox Music Off

    Now my friends who have 920s or 925s don't suffer as much drain as I do. Is there anything I can do to stop it draining so much whenever I want to do something on the phone or is there something wrong with my phone? I've turned literally everything off or low to prolong the battery as well.

    Any help or info would be greatly appreciated. Thanks.

    It's normal and expected for the in-use battery drain to be significantly higher than the idle battery drain. I would say there's something seriously wrong if that wasn't the case. If you're actively using the phone, you have the display on (even on low brightness that uses a lot compared to being off) and the CPU can't remain in its resting state nearly as much as when the phone is idle.

    That said, your idle consumption sounds high to me. I've been getting about 1 to 1.5% per hour. My settings are similar to yours except I use LTE, auto brightness (irrelevant for idle anyway), 2 email accounts set to check every 15 minutes, and double tap to wake.

    Hi tgr42,

    Thank you for your reply.

    I understand that using the phone rather than letting it run idle would use more CPU power but it seems that anything I do on it uses a lot and the battery run downs rather quickly. For example, web browsing with 1 tab earlier on 3G said I was using a drain of 29% per hour, that equates to just under 4 hours of phone usage. I just feel that whatever I do on the device really truly destroy the battery thus making me not want to do anything on it to make it last.

    I did do a soft reset yesterday morning after I charged to 100% and the phone stayed at 100% until around 10:45 (phone taken off charge at 8am) and it stayed around 1-3% idle but whenever I do anything on it, it really drains it. Is this the same for everybody? I thought WP8 was efficient on battery and only using a low speed (compared to other phones) dual-core processor meant it used less battery?!

    The battery is getting better the more charges it gets but I am rather worried that the phone cannot do the tasks its meant to do without running the battery down.

    Nevertheless, I keep my hopes up.

    Thanks

    Edit - forgot to mention that I ran with flight mode overnight, it used 10%.
