    I'll get about 22-24 hours (15-20% battery left at that point) before I charge up again. Bluetooth/NFC off, everything else on. LTE/4G signal is typically strong. When I listen to Pandora over LTE, it's about an 8-10%/hour drain.

    My phone has freaked out every once in a while, it'll stay hot after being fully charged and start draining inexplicably. I usually have to restart/recharge before it calms down.

    I've had a lot of WP devices over the last couple years, and ever since the upgrade to WP8 the battery life has been inconsistent. I've had 3 different 920s and 3 different 925s and found that both phones had periods where the battery drain was anywhere from great to disappointing to disastrous. I think this is either a universal Nokia firmware issue or a Windows OS issue.

    I typically use my phone in a light-to-moderate fashion. Lots of email (Outlook.com and Exchange), ~1 hour of calls, couple dozen SMS texts, handful of photos, Twitter, Facebook, Reddit and news apps. Very little IE usage, and zero games and only occasional navigation/mapping. I live in a strong, re-farmed LTE area for T-Mo. I rarely stream media, and when I do it wipes out my battery badly. I typically have BT, WiFi, LTE and Location on all the time.

    With these settings I find that some days I'll get 1.5 days of power. Other days I'm lucky to make it to 8PM. Some days things will go haywire and the phone gets super hot and the battery wipes out completely in just 2-3 hours. I've tried managing my background tasks and turning off WiFi, location and BT but nothing seems to matter. I haven't been able to effectively tie the issue to any one use case. My theory is that the LTE radio sometimes just craps out and starts heating up. Either that or I'll be in a spotty WiFi area and the phone is constantly searching/connecting and failing without falling back to LTE as it should.

    Also, streaming music and watching streaming video are brutal on battery. This is to be expected, but I find that the phone gets unreasonably warm with the video and the phone seems to not cool down after I stop. If my theory about the radio's issue are incorrect, it's probably just a issue with the way WP8 handles task management and tomb-stoning.

    Hi, i bought my Lumia 925 just 2 days ago.
    The first day the battery goes from 100 to 0% in less than 9 hours, with moderate use. I was pretty concerned about this, but i recharged again to 100% and i went to cinema. After 3 hours (i haven't use my phone inside the cinema!) battery was to 70%.

    Really not good, uh?

    I already disabled bluetooth, put touch screen sensibility to normal, disabled double tap to wake, disabled nfc, set max speed to 3G, but it doesn't helped.

    After seen this 70% i disabled the glance screen too and, it totally fixed it! this happened 10 hours ago and i'm still to 70%! (almost no phone using, i sleeped!)

    Glance looks pretty broken on my lumia, it sucks battery as hell, maybe someone in this thread with battery problem can try this too. I have GDR2 with all the latest updates (i'll wait lumia black for GDR3)

    I want to know if there is anyone who has 925 and gets 2 days of there battery?

    i work all day and only use internet for an hour. I don't have any social media apps(fb, twitter,). I have all connections such as wifi Bluetooth, location turned off. All aps disabled in the background as well as xbox sharing is off.

    my battery only lasts around 8 hours . Is this normal? How long does yours last? Is there anything else i can do?
    i watched a Movie of 2 hours duration after its fully charged and then it showed

    I've had mine since yesterday. First day got me worried because i drained my battery to 50% after 1 hour of constant usage. I started disabling settings and now its almost acceptable: today i unhooked from the charger at 7am, and had 28% at 18pm.

    Settings:
    - sun readability off
    - high touch sensivitity off
    - glance off
    - tap to wake off
    - bluetooth and nfc off
    - wifi and mobile data on

    Usage:
    - no phone calls
    - 10 sms's
    - less than an hour of messing around with apps and surfing

    I really like the device a lot, but if this doesnt improve im returning it. Its like an luxury aston martin that stops working after 1 mile.

    I wasnt planning to set my phone to edge today, but i had edge from 7h to 15h, and was surpised bu the battery. The difference in power consumption between edge or 3d is indeed huge. On my previous device (android) this was fixable using an app called "juice defender" which worked like charm. On WP we dont have that, and its impossible to write an app like juice defender, so instead i posted a suggestion to the idea box:

    Separate "highest connection speed" for standby and unlocked. – Feature Suggestions for Windows Phone

    This will allow users to mimick the behavior of "Juice defender" on android and will give an impressive battery boost to all WP devices, since 3G uses alot more power than EDGE (especially on devices such as the Lumia 925)

    It also makes sense: you want the speed when browsing, and while using apps, but it does not matter that much when syncing mails or updating live tiles.

    It cant be more than a couple of lines of code ...


    So if you have some votes to spare ... ;)

    this looks like a good idea.. BUT
    i made a few tries and with my italian operator when i switch max connection speed from 3G to 2G i lose the connection to my carrier, forcing phone to reset it and cut all the current connections.
    i don't know if it happen for all users but it can be pretty annoying!
    I think the real problem is somewhere else.. with my old lumia 720 (2000mah battery too) i can do 2 days of use with one charge and moderate use. I have a lumia 925 from some days and it's hard to get at the end of the day. I'm still making some more concrete stats using "Battery sense" (i love that app) but its hard to get an accurate battery behaviour :( just this morning it lost in 1 minute 11% battery (while in standby) and after 3 hours its still there, without any other battery loss and very light use. Still investigating!

    edit: and i think your suggestion will need some more than "a couple" line of codes :( you must define exatly "when" reduce speed to 2G. Ok, you say when phone its in standby, but if phone is in standby and an app is downloading something? Or when your non-offline navigation software is downloading new area maps? You must find a way to define when an app still need huge bandwith use when in background! You can give developers this possibility but this mean new API and new implementation for all existing app that may need that. Or you can try to implement an "euristic algorithm" to "guess" when you can reduce to 2G without any repercussion to any app, but this mean you must run this check lot of times while phone is in standby and so itwill consume more battery.. well, probably there are even other approach to the problem but its not "that immediate" to implement, debug and release :(

    I just picked up my 925 a week ago. Battery is about 50% as good as my 810.

    It's pretty disappointing. And even more so because charging in the car is difficult if I want to plug in audio. Proximity of those two wires distorts sound.

    Was down to 30% today st 2pm after taking it off charger st 8am. Hopefully battery life improves with use because this could be a problem as my job situation changes.

    i had your same problem, my battery life magically improved with a simple soft-reset! now in standby i lose 1% every 1 or 2 hours with 3G and Wi-Fi on always on :)

    Complex rules results in complex code. If you keep the rules basic the code will be basic and less errorprone. Phone locked: lock-speed, phone unlocked: unlock-speed. Most background processes download tiny bits of data. Some are heavier and download images etc ... but that shouldnt be a problem.

    A connection only appears slow when you're actually waiting for the response :)

    In the meanwhile, im getting a full day on my battery. Not sure why, but i did set my connection explicitly to 3G, although i dont recall what was the default. Could i be that i had 4G selected by default?

    I have Lumia 925 for a about a week now. I am bit worried now.

    In background apps i just have whatsapp, evernote and battery app active rest all are blocked

    Wifi is always on.
    BT is off
    NFC off
    Locations off
    Glance off

    Continues use of whatsapp for an hour or so the battery easily drains 20%. My battery lasts about 5-6 hours and occasionally 7 or 8 hours. The standby time is good, it hardly uses 1% an hour.

    In this 1 week - my battery died twice and i generally put it to full charge when it touches 10% or so. It takes less than 2 hours to charge.

    I am in India. I got my phone from USA ATT. We use 3G here (NO 4G). But my phone shows as 4G. not sure if it is trying to find 4G signals here. Do you guys think this is using up my battery? If yes, is there any option to turn off 4G and use 3G instead?

    Do you guys think my battery backup will increase?

    You should select 3g by going to mobile network in settings and you will see a box with highest connection speed.

    I charge my phone every 2nd to 3rd night. My setting and usage are below.

    What's app
    Bing weather
    Bing news
    Outlook (push)
    Gmail (15minutes)
    Bluethoot on
    Wifi on when awake
    Glance (peak)
    Tap to wake up
    Brightness on low
    Network 3g

    Those settings never change. I find that the battery is on a par with the battery in my Sony Xperia Z1 which I don't use anymore, it has been in its box for the past couple of weeks.

    My battery life is pretty much on par with my old Lumia 920, mediocre at best. With light-medium usage it can last a day. With heavy usage, it lasts a little more than half a day. I've had it for 2 months on T-Mobile USA.

    What's app
    Gmail (15minutes)
    Wifi on
    Brightness on low and auto
    Network 3g
    Facebook

    Nothing more.. not sure why it doesnt last long..

    Is it because i use 3G but the phone displays 4G near the tower icon? do u think it is trying to look for 4G ? Do we have any option to de activate that ?

    I just love the phone.. but it is so irritating that it discharges in less than 6 hours.

    Glad to be back on WP. Just switched from a Galaxy S4 on Sprint to the 925 on AT&T. Overall I'm pleased. I was pleasantly surprised by the battery life. With light use I can usually go three days. Occassionaly it acts up and drains extremely quickly requiring a warm reboot(vol. down and power held until it reboots). But overall good, quite good. Btw, bt off, wifi off, glance screen off, battery saver off, display brightness on low.

    I'm pretty satisfied with my lumia 925 battery life. Is pretty close to the lumia 720 which has the best battery performance from all lumias besides probably the new 1520.

    The phone is currently with GDR2 and with almost 2 weeks usage with:

    -bluetooth, gps and nfc on
    -connected to LTE with 2-3/5 bars of signal
    -wifi always on
    -auto brightness
    -glance screen on (changed to peek option recently)
    -black background
    -high sensitivity touch on

    My background apps are:
    -two gmail accounts syncing every hour
    -data sense
    -skype
    -baconit
    -battery sense
    -facebook
    -myTube
    -bing news
    -twitter
    -viber
    -whatsapp
    -and many others which only update tiles but are not visible (I actually reached the 15 background apps limit today)

    My typical usage is:
    -couple of sms a day
    -short call a day
    -something like 2 hours per day with baconit
    -an average of 2-3 camera shots per day
    -some file sharing to dropbox and skydrive
    -some minutes of internet explorer
    -using a bit of every other app

    Maximum battery duration was 1 day and 20 hours. If I use the camera a lot or pick a game, it gets 1 day and a couple of hours.

    Remember that the phone battery takes 1 to 2 weeks to get calibrated properly. When I got the phone it rarely got past 1 day of usage. Now it gets a couple of hours more to a maximum of 20 hours.

    For the past 2 days i have been getting atleast 20 hours of battery life.

    My usage is high. I am on whats app atleast 5 to 6 hours every day, Facebook, email sync set to 15 mins and atleast 10 to 15 photos, music and few other news apps like weave.

    The old change i did was switching of my data and using only through wifi. There is a massive difference in my battery life.

    In standby i hardly lose about 3% in 7 or 8 hours and on regular usage i am losing about 4 to 6% battery.

    I some how need to get the highest connection speed settings enabled on my phone, so that i can set my max speed as 3G instead of 4G.

    I don't have any issues with the battery until i started using wireless charging!
    i charge overnight using wireless charger
    Few calls of 2-5 minutes and about 2-3 hours of whatsapp/kik
    some browsing on wifi
    And at the end of the day battery gets to 10%
    mobile data is always off. Bluetooth nfc off. Glance set to peek.
    anybody else who uses wireless charger?
