    Tapatalk for windows phone sucks. That is why. I am a mobility consultant and I have an iPhone 5s, a BB 9900, a lumia 1020 and an HTC One :-)

    About the Lumia, go to settings/applications/background tasks and disable the ones that do no make sense. I found that some windows phone apps put themselves in there even if it makes no sense...

    Very true. There was a period of about three days where my battery was inexplicably draining faster than usual. It was driving me insane as I was wondering why. I checked my background tasks, and sure enough, Dominos was running in the background, after I opened the app for the first time a few days prior to order some grub. I disabled it and sure enough, my battery life was back to normal. What Dominos was even doing? Beats me, all I know is it was sucking battery and offering me no noticeable benefit.

    Just chiming in on my experience. The battery life is AWESOME as long as you're not taking a million pictures... The Xenon flash uses quite a bit of juice.

    For everything else, apps, calls, texts, etc... It's amazing. My old Lumia 900 would get down to empty on a full charge in the late afternoon or evening with how much I use my devices for e-mails and calls. The Lumia 1020 under MORE usage, usually it at around 60-70% by the end of the day. Sample is from using it for 4 days!
    Ha ha, yup! My previous Lumia 900 got meh battery life. It was enough to power through the day, but like my iPhone-owning companions, I was often in search of a power outlet to avoid my phone dying. Switching to the Lumia 1020, WOWZA! Great battery life, plus I have several hours extra in reserve thanks to my Camera Grip Case.

    About Xenon flash, my good sir, TURN OFF FLASH THIS INSTANT! Flash should always be a last ditch effort, photos are much better without it. Do yourself (and anyone who might look at those fine photos) a favour by turning flash off and instead using the superb low-light capabilities of your phone. ;)

    one thing to test the battery life (for those who think they got bad device) is to turn on AIRPLANE MODE and then turn on WIFI then try browsing using WIFI only and do activities using WIFI only (that rules out calling and SMS).. if you still experience extreme draining even when using WIFI and AIRPLANE MODE turned on then maybe you have a bad battery..

    my own experience showed me that using WIFI only (no cellular connection) accesing a local WIFI AP, my LUMIA 920's battery life is very excellent.. but when i turn on the CELLULAR function , the battery start to drain alarmingly. The test is done at my home and close area surrounding my home where the provider's 3G signal is weak and the phone keep switching from EDGE to 3G to EDGE thus ruining the battery life and making it very hot.. but when i test CELLULAR at my office the phone behaves more like ordinary phone with great battery life , since the 3G signal there are good.

    so before you think your battery is bad, check your device's endurance using AIRPLANE mode only (WIFI)..

    My experience: Battery life is excellent on light/moderate usage with full signal strength. I'll generally be able to get 12+ hours by using the device for about an hour of music over bluetooth, sending about 100 texts, a short phone call here and there, a picture or two, and reddit (baconit). That's about an average day for me. I'll unplug around 6:30AM, and be at about 20-30% by 9PM. Around this time, I have battery saver mode set to kick in (less than 20%), and I'll be able to use the device for moderate usage for the rest of the night.

    However, the good battery life can change rapidly if you enter low signal areas (including low WiFi areas, so best to turn off wifi when you're not near your router). Games, many pictures, lots of streaming, or anything GPU intensive will also KILL the battery.

    The strange part for me is that any phone I've had from the N8 or earlier never experienced the issues with intense usage or low signal. Obviously games and videos drained if faster, but never as fast as the 808 (yes, S60 had the issue too!) or later. I hope its something that can be improved in updates.

    Im curious what other people are reporting for hourly usage while the phone is in standby for a while. Like when I sleep, I seem to get 4% drain/hr. While thats not bad, its not really stellar either. I seem to be upwards 7-8%/hr with serious usage. I always have a strong signal, for reference.

    4% drain while idle is pretty bad. I'm seeing 0.8%. I have wi-fi always connected and an LTE signal present (sometimes weak, sometimes strong). When I see something like 4%, I know it's because I screwed up and some app or something is eating the battery.

    At .8% you can't have many apps running. What do you use? 4% may sound bad, and I honestly dont know for this specific device, but from previous devices I've owned, if you're using apps that update in the background 4%/hr isn't terrible. I have weather and email every 2hrs, FB, Twitter, 6sec & 6tag, WhatsApp and a couple other apps that update data every now and then. My last 2 Blackberry's got around the same and they are known to be fairly efficient. They were slightly better in standby cause I didn't use as many apps though. I remember my old Bold 9000 getting ~2.5% in standby and all I really had updating was BBM, weather and email/etc. That was an average number too, compared to other owners on Crackberry.

    I have not set mine up to conserve battery in any way. I recorded 13GB's data last month, so I use my devices. 😃

    Without doing anything to try and conserve battery, my battery drainage usually hovers around 4% an hour, and I land between 20-24 hour battery life. I have several apps that update in the background, as well as leaving every single service under the sun turned on, so I'm not disappointed. Could I get more if I turned these features down/off? More than likely, but 20+ hour battery is more than enough for me, and as I said, still got a few more hours in reserve, thanks to the camera grip (which I use as my primary case).

    I have 2 Outlook/Exchange-based email accounts set to check every 15 minutes, Weather Wallpaper, Skype, Battery Sense, and a few games that use infrequent push notifications to update their live tiles (a few times a day at the most). I do have FB integrated into the People hub but as far as I can tell it's not doing anything in the background.

    I agree that if you're running a lot of stuff in the background that is receiving updates on a frequent basis, 4% may not be terrible. It's up to each person to make his or her own tradeoff. Hopefully the extra battery consumption is being put to good use, because 5x less idle battery life is quite a big difference.

    hmm its scary how the phone dont drop even 1 percent when put at my home with Airplane mode ON and Wifi ON.. somewhere inside lumia 920 must be a very efficient o/s yet when the phone taken out from home and start using cellular it all down hill from there .. the battery saving mode is a bit help though not much given that the phone keeps changing signal from E to H to H+..

    btw what is faster ? 3G or H or H+

    I used the 920 before this. and I used to have to charge my phone during the day at work. but I havnt charged my 1020 yet at work (although I have only had this for about 2 weeks)
    it takes me about 12 hours to go down to 25%. I am pleased. it is much better than the 920's battery, 920 wouldn't have last me half a day.

    my average battery rate is around -8% / hr, average battery life is 8.5 hours.
    the first few charges seemed like it took forever, after that, it charges super fast.
    I have glance and double tap disabled. but I use alot of camera, music, twitter, whatsapp, and line.

    and oh, I use a light theme. :)

    So monitoring the last 2 days, I get 6-10% drain/hr (recorded by BatteryPro+) when I constantly using the phone for WPCentral browsing, 6sec/6tag, FB, etc. No streaming though. I've noticed Fhotoroom destroys the battery though. I'll try to monitor tonight when I'm at the gym, just playing music stored on my device. Curious if it is worse than just standby. I know it shouldn't really be, but I'm curious.

    I know I use my phones more than most people. This type of battery life is really on target with my past 4 phones. I can easily kill a battery in 7hrs without streaming music/video if I wanted. Admittedly, I was singing praises for this phones battery performance the first day or two but now that I have more apps running and stuff, its just "meh, same as usual."

    When I'm using this phone that much, it gets really warm. Warmer than any other phone I've used. I've read reviews saying it gets warm when you use the camera alot, but any app that pounds the processor causes this heat. Video games, streaming, Fhotoroom, Vine, etc... Frankly, when I'm charging this phone I kind of worry about using it alot cause it gets so hot.

    Yeah, the heat worries me too sometimes, especially the camera sensor (made of aluminum) can get really hot. I've learned to not charge and do processor intensive tasks at the same time. And there have been a couple instances where I've turned my device off as a precautionary measure, to let it cool off (didn't automatically shut down or anything, I just turned it off because it was worrying me).

    Well, it all depends on what your ideal battery life is. The more you expect from this thing, the lower what you define as "extreme drainage" is.

    I thought the battery life was a little poor initially but I've had the 1020 for a week now and it's performing as well as the 920 which in all honesty is slightly better than smartphone average.

    My experience with the battery has been mixed so far. I picked up a 1020 a week ago and was so excited with having a new phone/OS that I began setting it up to get the most out of it. I quickly signed in to my email and social media accounts, downloaded a ton of apps and played around with all the settings and features (all while charging and connected to WiFi). The next day at work, it became clear that my battery was not quite right. I used the Battery Pro + app to track my usage and found that I was averaging around 9-10% drain an hour. My battery was down to 20% by lunch and I ended up charging it a total of 3 times in that one day (I did not let the battery drain completely, I would charge it once it reached around 30%).

    Just to be clear, my usage was moderate to high throughout the day: I had one email account syncing every 30 minutes, made about 6 calls, sent a handful of texts, received around 200 messages in a Whatsapp thread, used the GPS for about 20 minutes, streamed music for about 30 minutes, shot three 30 second videos and snapped about 30 pictures at night with the flash on. With that said, I let the battery drain empty that night and charged it back to 100% overnight.

    The next day, I used the phone much less: I streamed about 40 minutes of music, made 3 calls, and sent a couple of texts/Whatsapp messages. I noticed a slight improvement in the battery drain which was now between 7-8% an hour. I started reading this forum and found that there were a few things I could do to extend the battery's life like disconnecting from Xbox, switching off location services, and blocking background tasks. I followed all of the steps suggested, but kept the double tap to wake on and glance set to peek (these features were too convenient to switch off, and from my experience with the N9 they really don't affect the battery much). Even with minimal usage throughout the day, I was on battery saver by late afternoon and found myself having to charge just to get through the night. This seemed strange as users in the forums were raving about the 1020's battery life, stating that they got 2 days on a single charge and were averaging 1-2% drain an hour.

    The next night, I charged my phone to 100%, unplugged it from the charger, and put it into flight mode. I made sure there were no apps running in the background and went to sleep at 1am. I woke up at 7 and found that my battery was at 70 %. In 6 hours it had drained 30% = 5% per hour doing absolutely nothing. Now I knew for certain that something was not right. Reading further into the issue, I learned that poorly coded applications were likely to blame. However, since I had installed about 20 apps at once, there was no easy way to find the culprit, so I reset my phone in order to start with a clean slate.

    After resetting the phone, I set up one email account to sync every hour and downloaded the Battery Pro + app to monitor my battery. I also blocked Here+ from running in the background, disconnected from Xbox and switched off my location services. The battery improvement has been like day and night. I now average 1-2% drain per hour and for the first time since buying the 1020 Battery Pro+ shows that I have over 40 hours of battery life left. I am now certain that it was one or more applications that were causing the battery to drain. Moving forward, I am going to download an application a day and check to see what its affect of the battery life is.

    With that said, I really think that Microsoft should improve the screening process of apps, as a couple of poorly coded applications are damaging the performance and image of their hardware. I had the willingness and patience to reset my phone and get to the bottom of the problem, but I imagine that many users out there will simply return their phones to the store, opt for a device from the competition and then complain of their negative experience with Nokia or Windows Phone to their family and friends. It's a shame because Nokia is churning out some remarkable devices and I suspect that many of the battery issues reported with the 920 and 925 also boil down to a handful of bad apps.

    Anyways, that's my experience with the 1020's battery life so far. If I can manage to keep the drain at under 3% as I install more apps, this phone would have far exceeded my expectations in terms of battery performance.

    If Microsoft could somehow improve the quality of apps so they don't wreck the battery, that would be great. That is a very difficult problem though. Who judges how much battery use is acceptable? Different apps are going to need different power consumption to do their different tasks. Maybe they could get more strict with hard limits on background activities, but that may have other unwanted results. The restrictions in place now are already hurting the platform compared to others that allow developers to do much more.

    As a developer, I think as long as humans are coding apps there will always be poorly coded apps. Aside from education and testing, there's something Microsoft can do today to make a huge impact on this problem. Make it easy for users to pinpoint what specifically is draining the battery! Right now it's impossible unless you go through tedious testing one app or setting at a time. And what happens after you've achieved a stable setup and something changes? Some app gets updated, or just changes behavior based on some server-side change perhaps, and now you're back to square one, not knowing what's draining the battery without starting over with the process of elimination.

    It's really shameful that there's no accounting available to the user of what's draining the battery. This should've been in the OS from day one. But Microsoft's strategy on this and other usability issues is to bury their head in the sand and pretend everything's ok. This is not a viable strategy for achieving meaningful growth in a competitive space.

    Yes! I completely agree. This is a much needed feature and is probably easier to implement / less of a deterrent to developers than making app submissions stricter. Hopefully Microsoft will introduce it in some future update.

    Just an update to my earlier post. The improved battery life I experienced after the reset didn't last long. With light use, the battery drain went back to 5-7% on standby. I sent the phone to Flextronics in Canada for repairs. After 2 weeks they sent the phone back with a slip saying that they re-installed the software. A rep from the service centre swears they replaced the battery, but even so, the phone is no better than before. I can't squeeze more than 14 hours on a single charge and the standby battery drain is still around 7% an hour. I reset the phone again, switched SIM cards and ran it for a day in flight mode. Nokia doesn't want to acknowledge that I may have a faulty unit and are simply asking me to send it back for repairs again. I'm at a point now where I'm considering selling the phone. I like my 1020, but its pretty useless when I have to keep it hooked to a charger.
