    Here's what I'm going to do. Dump this phone and OS in a drawer and go get a Note 2 or wait for SGS4. I'm hoping wp8 is like fine wine, just needs to age a bit. I'll revisit it in a couple of years and see how it is them.
    So you are considering dumping a device by a manufacturer that provides regular updates and awesome software releases continually (ie supports their product) for a company that is known for not supporting their products once sold (Samsung) and for a device of theirs that isn't even released?

    You know, I have a 2 yr old Razr Maxx I use for work running latest and greatest version of Android 4.1. And Samsung flagship phones get the updates in a timely matter. Maybe not day of release like Nexus devices. I have the latest, greatest Portico on my 920 and its still one to two years behind what my two year old Android will do with its updates that you think it doesn't get. So, what exactly will I be missing Watson? Android will always be two steps ahead of WP even if Samsung phones don't get an update.

    Another funny thing. I was over on Android Central today and the first post I found on a SGNote 2 was a battery life post. They weren't complaining, they were praising the battery life. I'm sorry but wp8 and 920 bring far less to the table than Apple and Android had two years ago. Hardware and software.

    One thing I've noticed is that if I allow my 920 to charge completely until the light turns off on my qi charger (sometimes it'll display full but the light is still on) it will actually last much longer. It doesn't hold a partial charge very well though.

    Ia there any app that can monitor what app or process is using up so much of the battery? I would pay a few bucks for one such app.

    My battery was terrible when I first got my 920, I was very upset because my iPhone 5 battery would last a day and this wouldn't. Ever since I shut off LTE (since I do not have it in my area yet) and just keep it on 3G only switching wifi on when I need it, my battery will last me almost 2 days. That is with facebook and emails and browsing for new apps and stuff. I can't beleive how long this things lasts me especially with all the live tiles and everything, I love it! I'm reading on here though to let your battery drain once in a while, How often should I do this?

    Surely a CPU monitor would be a great app for WP8? Had one on my old Desire in the status bar, just a little bar graph- when idling would show approx 10% use, when browsing or using Maps would show 90-100% usage. Wouldn't tell you which app was misbehaving, but at least you would know that something was wrong. Happened a few times to me, usually uninstalled a certain app or did a soft reset. My unlocked Titan thankfully doesn't seem to have any problems like this.

    I'm waiting for a battery monitor app that actually monitors the usage by an app or process. I guess based on available API's its really hard to code one... but hoping it would come. My doubts are all on WP8 that is hideously running some rogue battery draining processes in the background. I wish MS gives a Ctrl+Alt+Del equivalent to see the background processes..

    I have done whatever has been told on this forum to improve battery life, removed programs which are accused of being main culprit, soft reset and switching off nfc,location background tasks but nothing seems to help. Now i don't have any tiles acting as active tiles,all are static,reducing the fun of use on this device and battery seems to be ok while you don't use it but as soon as you start using it ,it starts scaring you.. i have seen, before starting to use this device battery showed 3days and 7 hours of time remaining but using browser for 30 mins drained it to critical level and less than 1 hour left .. and it switched off of its own in another 10 minutes. so really don't know how to work around it and make it last longer while actually using it. I really love the device built and wp8 concepts but to actually get in love with all this it needs to work in fashion they claim it to . i have tried contacting nokia and ms but no reply from anyone.

    Amit, I guess you have a serious battery issue and take it to Nokia care... If I use browser I lose about 4-5% at around 20-30 minutes usage on wifi. If you are draining within half an hour you have some hardware issues with the phone I guess...

    Yep, amit, yours sounds reaaaly bad and i'd defs seek out a replacement. BUT! How long have you had it? Give it a month at least (i know its a while, but if you phone has no other issues i'd hold onto it).
    Lazysundays battery seems ridiculously good. I max out at about 10h every day (which seems to be fairly normal on these and other forums) and that is with moderate usage, probs 1-2h of internet usage. Turning off 4g or all data completely makes no difference at all.

    Edit: I've owned mine since release date (3 months) and have factory reset, flashed different firmwares, numerous resets ect.

    Well, overnight my battery only went down 3% so the battery seems to be lasting longer. But now I just had to do a soft reset when it wouldn't respond. This is the third time in two weeks I needed to do this.

    I am getting some odd results, but I haven't really spent much time figuring out what is bad or good. Yesterday it was draining fast, probably 45% down from the morning until lunch, the draining at a rate of 5% per 15 minutes just sitting idle. I did a soft reset (just learned about that above somewhere), then used the options shown in the CNET video, yesterday afternoon. Immediately it slowed down to the point I still had 35% left at the time I put it on the charger, maybe 11 PM. So, dropped maybe 55% in the first 6 hours of the day, then only 10-20% the final 10 hours of the day. After picking up the phone this morning, with a few calls and a fair number of emails, plus running gMaps for 20 minutes in the car with the screen on and no charger, it's now 11:30 in CA, I have had the phone off the charger for 5 hours and it's still at 93%. (I would like the % number to display next to the battery icon in the next release.)

    I have noticed, when I use Nokia Maps (display always on) in the car, even with the charger connected, it drains the battery like an open spigot. I am not happy about that. At least with my iPhone I could run MotionX Drive with a charger and still have it charge up. I just bought a 900 mA USB charger, but it doesn't seem to be any different than the 300 mA USB charger I started with. I have one other option to try, but I doubt it will be any better.

    Man you and lazysunday makes me believe that i got a dud....
    i have contacted nokia and awaiting there reply on it. I have been using it now for 10 days.. but somehow it never holds up the charge. And i don;t see any reason for it to improve if it hasn't improved a little in last 10 days. Update about today... i disconnected from wall charger at 08:15 with 100% charge. checked overnight whatsapp messages(3) emails(5) and sms(2) . at 08:45 played car racing game for 15 minutes,read a internet page for 10 minutes and by this time 09:20 battery was down to 72% . at 10:30 no additional use other than sending one message on whatsapp it was down to 61% .I put it back to charging and at 12:15 it only charged to 71% :( . It takes **** lot more time to charge than actually getting discharged. Now it is 14:05 and it is again down to 59% ,i have only made a single call for about 20 minutes.
    :( :( :( :(

    Hi, when i bought my lumia 920, the battery used to last more than 24 hrs, but then all of a sudden it started this issue of fast draining. All i did was a factory reset. The one which deletes everything and then i had to reinstall all the apps. Now the battery is working perfectly, gives me 24hr + with bluetooth on, wifi on and nfc on.

    Just try Nokia DC-20 (2 x 1000 mA), because there is a big difference, in practice, with different car USB chargers (even they might look the same, with the same output number) ...

    Hi! All,
    I want to know one thing, when i connect to wifi then technically data connection should be swithced off it's own as there is connection to data through wifi but i never see it happening.. wifi and cellular data(3g) both remains connected. so actually it uses which data bearer??? and maybe this is one cause of battery drain as well. Is it a bug or what?
    i have never seen in any of my previous phone connecting like this to both connections.

    Yup, unfortunately, the phone is connected in both modes. While wifi is available, the cellular data is not used, however, it is connected in data mode. Probably reason for such a design is to keep any data streaming to continue over 3g once the phone is out of wifi zone. I have a great battery life the moment I turn off data mode on my phone, probably lasting two days... but what is the purpose a smartphone without always on data. I felt a smartphone should optimize the resources. Your battery drain is also dependent on how good 3g coverage is in your area. I too had a couple of bad days when I was losing charge really fast as the phone was set to 3g and it was constantly trying to connect to poor 3g network instead of strong 2g network.

    Moreover, I guess Whatsapp in the problem in your phone. It continuously streams data to keep itself alive working in the background instead of using push notifications which causes the battery drain. I removed whatsapp and not going to use it till they get rid of audio API's and background streaming.

    i don't think whatsapp is any more culprit after their back to back updates.. it works now more efficiently and doesn't work in background apps,i have checked it. It works purely on toast notification system and once you open the app it fetches the messages. there are certain flaws in the OS like this.. when there is toast notification the message should automatically be in app rather than fetching it after you open the app. Yes you are right smartphone should be optimised to work with all features working atleast lasting good 12 hours of heavy usage.

    Another update for me: I took my phone off the (wireless) charger yesterday around 6:30 AM, and now as of 4:30 PM the next day, I still have 28% battery life yet. This was the level I was at on Wednesday after only about 6-7 hours, with no real difference in use, other than the changes I mentioned above. I can live with this, just need to know how to keep it that way.

    Yes, soft reset (not sure exactly what that did) and the suggestions in the Cnet video. The link is in Post #5 on the first page of this thread. Here is the link again. There was one Nokia app that I did turn off in the background, it might have been City Lens or Local Scout, which, I think, was mentioned in the video. That seemed like a likely suspect as it was constantly looking for surrounding information.

    I know this is one of those 'I left the fridge open and now I have great battery life!' stories, but it's happened enough that I believe it: gMaps pro can empty the battery in my L920 in record time. The worst part: it keeps draining even after I back out of gMaps pro. Even if that's a bug in gMaps, the OS shouldn't allow it. You know, assuming that I'm not imagining all this.

    Also: Mark3dyn, your avatar should be an album cover, if it isn't already.

    That would have been a good album cover when I was in my band in the late 80s/early 90s (electronic/industrial). That is me in my dad's mad scientist lab, probably '69 or '70. It's odd that gMaps seems to make your phone drain, and gMaps seems to not cause me much of a problem at all, Nokia Maps seems to be my battery valve. I still had 20-something % last night when I went to bed, but decided to put it on the charger anyway.
