So across all roms I have tried the display literally destroys the battery life of my phone. While the screen is off I get fine battery life. But when the screen is on I can watch my percentage decrease about 2-3% every minute so after a half hour of browsing my battery is gone.
I have an extended battery as well but that just prolongs it slightly. The brightness is about half right now. Is this normal?
Does not sound Normal but display is the largest user of battery( unless one can use the phone with display off
I had as video streaming yesterday for 30+ min from 80% it went to 14%
haven't tried keeping just display on should try that ...test for tomorrow

I have my brightness set to 15% and it still sucks about half of my battery use. The display is unfortunately nearly unstoppable when it comes to battery drain. HTC and others are like "BIG PHONE DISPLAY!!!1!111!" we're all like "I can haz batteries?"
That description is the best description of our issue.
But an answer to your question, drop you brightness to as low as you can stand it and if possible try to limit the amount of times you wake the display in a day the juice it requires to turn it on is greater than it needs to sustain the screen on.
I would say yes for the most part. We have a fantastic and power hungry display...the price for greatness?
That being said, its not so bad dropped down to 25% or so, and easily viewable, except if you're outside.

Alright thanks. I just wanted to make sure my phone wasn't experiencing something that is atypical. Other than that I do love this phone and the developers
It's hard to say. With screen on I loose about 1% a minute even with auto-brightness turned off and the screen at around 25%.
There are others on the forum that have made rather amazing battery life claims so it may come down the the individual device.
I have debated about returning mine for a different one to see if I get any better performance.

I'm not sure I would bother chasing longer battery life with new devices. A lot of those are very optimized use cases -- either all on wifi, all in areas with great signal, or lots of screen on time but they don't mention what brightness. The fact of the matter is the phone has a tiny battery and uses up a lot of power for the display and radios. I get somewhere between 12-16 hours on a stock battery, depending on where I am and how much I use the phone (generally I'm a pretty light user, but I do leave 4G and Bluetooth on all day).
So how about the battery in the Lumia 920.
After the Lumia 800 failed in this area it would be great to know if the 2000mA battery is big enough for this whole Thing

I've been using it for half a week now and battery is phenomenal even in LTE all the time. Will last you a full day off not a day and a half with moderate use. Full day heavy use probably.
You have nothing to worry about this time. Nokia got it right.
More details here: http://forums.wpcentral.com/showthread.php?t=200158
Mine sucks right now. I'm just using it for normal email updates and a few downloads from the app store and it'll be on 40% by 4-5pm. I've turned off a lot of the background updates on the live tiles too, but it's not making a difference.
Screen on time is disappointing.
Mine has excellent battery life. 2 days on a row on my last charge.
Ppl with battery life problems, I would suggest to visit the Nokia support forum.
Important
If you disable NFC (tap+send in settings) you have a HUGE improvement in battery life.
As mentioned above, disabling NFC and background apps will greatly improve battery life. I am more than satisfied.
I leave my data connection on 2G most of the day and it seems make the phone last all day, with heavy use. If I really need the faster connection I switch it to 3G. This seems to work for me
Full day, 3G use (using on a 3G only carrier, no LTE unfortunately). Moderate-to-heavy usage, not a problem getting back home, chilling on the sofa, doing what not, and having enough battery to last until bed time. FYI my day starts around 8-9 and I head to bed around 11ish+.
I hear battery life isn't as good when NFC is on. Don't know though, I never have NFC on anyways (really don't see how useful it is atm).
Battery saving Tips
This battery saving tip has been overlooked since WP7 first generation devices. The reason why some ppl will be having huge battery drain is due to apps running in the background. So, you need to think about the apps that you actually need to run in the background. Make sure all your email accounts are on the highest interval time to be checked and/or "as the item arrives". When you select as the item arrives I believe true push is being used which if you don't receive tons of emails will save battery in the end. The other apps settings are located here start screen>settings>swipe over to applications>background tasks>and block all apps that you can that don't need to be running background tasks. I for instance only have accuWeather app running background tasks. Another thing is you need to be aware of apps power usage...i noticed that accuWeather is far better at using less power consumption than the Weather channel app. Other tips are common knowledge. Disable NFC, use WIFI when available, turn off high sensitivity if you're not needing it, use low time-out for shutting off display and use low brightness. Be efficient!!
Good
Lasts me about 1hr for each 10% increment. About the same i was getting with the S3. While playing music its battery life seems to last longer than leaving it on standby :S Find standby kills battery some reason, just recently turned of nokia drive background app, hopefully that makes it last longer
Battery life has been excellent for me. Mine was fully charged on Wednesday morning @ 8 AM and was at 48% when I put it on the charger Thursday @ 2 PM with moderate uses. Unexpectedly, the battery life is much better while on the LTE network than when I'm using my SIM card not registered for LTE usage. Standby drain is very very good.

That's because WiFi stays connected when you're streaming music, whereas WiFi disconnects when on standby. Known windows issue that should be addressed by ms soon.

I get great battery life unless I enter into an LTE area. When I do, my phone gets VERY hot and the battery runs down in a few hours. Even if I'm not doing ANYTHING with the phone. Strange...

How do you switch the 920 to 2g mode? I only have 3g and 4g in the options on max speed? my old lg wp let me set either 2g or 3g, huge difference in battery life on that devic.
to be honest tho so far i'm impressed easily outlasts my old phone, just tried turning off the high sensitivity on the touch to see if it makes a difference.
also run down the phone till it turned itself off last night, tried turning it on got the warning icon of low battery, did it again then it started, data connectino wouldn't work battery said 0% remaining and it lasted just under half hour with me playing mirrors edge, makes me wonder how accurate the battery % is
Battery capacity seems to have been cut in half!
When I first got the 920, at 100% the estimated battery life would say 1 day and X hours. Now (2 weeks later) when my battery is at 100%, it now says 13-14 hours of estimated life. My battery also drains much faster now than it did in the first week of owning the 920. My use of the phone has not changed over the last two weeks. I'm always in an LTE area, WiFi on and I use bluetooth from time to time. Is this an issue that other people are experiencing?
I'm trying to figure out if I need to exchange my 920. Any help or advice is much appreciated. Thanks!
i found it was using 2% battery every hour whilst connected to a data connection - but not syncing anything, all backround tasks turned off. This seems a bit mental.
So it seems that battery isn't so good :/ Too bad because i was wondering to buy this phone.

After deep cycling the battery, I am back to the correct reading. I am now losing a little less than 1% of battery life per hour on standby!
I've had the HTC One X+ for a week now and it's a really good phone, however, the battery really lets it down. The battery drain is terrible on my phone. The phone is really good in sleep mode, only losing about 2% in 1 hour, but as soon as it's not in sleep mode, as soon as you start to use the phone, the battery drains like hell. For example, when I'm web surfing or using applications, it loses 1% like every 2 minutes and that's crazy!
I don't know why, power saver is on, switched to 2G instead of 3G, disabled Google Now, auto-sync, basically everything I think would drain the battery. Brightness is on it's minimum. I feel so restricted when using my phone! But I've read other people having really good battery life even with moderate use, so am I doing something wrong? Should I factory reset my phone? Is there something wrong with my phone? Can someone help me?
Thanks!!
Have you disabled all AT&T apps? They drain battery as hell especially ATT locker.

Under Settings/Sounds/Ring Tone untick the three options as they just have the sensors constantly checking, then under Settings/Power untick Fastboot.
Then get a battery monitor app like GSam Battery Monitor which pinpoints the power drainer. How many apps do you have installed? Dump the ones you hardly ever use.
Also, several charge/discharge cycles are necessary before battery reaches best performance.

I think losing 2% of battery every hour of standby is pretty bad. How many hours of screen time on do you get from a full charge to around 10%?

Won't lie i got the same problem you are facing right now. The battery life is horrible, in fact it only lasts about 3-4 hours gaming if i am lucky. Before 5 minutes i opened a game called "dead trigger" my battery was 94% after 5 minutes of playing guess what? BOOM 89% straight which is extremely bad from my point of view.
You know, you do have screen with a high resolution, and you're using the max of the graphic and other chips while gaming...and that costs power...most likely NFC is active, as is BT, 4G, brightness on 200%, the loudspeaker blearing some music out of the cloud, GPS on, and 15 apps not closed properly, weather syncing every 5 secs, and 700 apps installed from Happy Santa to FakeYourPhone!
I really can't get it that you complain about it. It is a mobile smartphone that can be used to play games. If your priority lies with the latter, have a charger handy with you! Play, enjoy, and stop moaning...Period!

Bad Battery Drain as well
I'm going to tack onto this thread. I got the HTC One X+ about a week 1/2 ago. The phone is amazing. It has everything I want, but I cannot make it through the day once without always consciously thinking about battery drain and how quickly the phone just sucks down the power. The following Battery Monitor graph is when I have JuiceDefender installed so it turns off the data radio whenever the screen is off or I'm connected to WiFi. I was on WiFi from 7:45 this morning all the way to 5:00pm. The drain on this thing is so fast. I didn't watch a single video today nor any games. This is all facebook data, internet data, and just some general playing on the phone. I also turn on the power save feature for Jelly bean so I turned off vibration feedback, brightness is turned down, and CPU saving is turned on.
Do I have a dud phone or is the One X+ really that awful on the battery? I'm strongly considering taking it back but every single other thing about the phone is great but if the battery on every One X+ is that bad I don't know if it's worth it. Please help assuage my fears or give me some advice on what I can do better.
Do you have Google now active?

I do. I kind of thought it was one of the neater parts of Jelly Bean. Is it a complete battery hog? This is my 1st android phone but I'm a long time Smartphone owner. I'm guessing by your question I should disable it and see how the battery performs.
It is an LTE phone though i'm on wifi 90% of my day. Background apps that run are usually Whatsapp, Facebook, and Linkedin. Right now I'm losing about 2% charge every 10 minutes if I'm using it. I gotta plug the thing in as much as I can just so I can use it. I'm perfectly fine with tweaking the thing, just not sure how much 'tweaking' is needed to get some better performance out of the things.
I'm wondering if Facebook is the problem... Just a thought...
The One X+ isnt that bad in terms of battery life in my experience, I've done 15.5 hours with 2.5 hours screen on time, Not sure what folks are expecting, Thats pretty average for a smartphone... That is with Wi-Fi on, LTE on, Google Now on, Autosync on, the little weather widgety clock thing on.. and pretty much me not doing anything besides closing apps when im done with it, I have Kik messanger and TextPlus on in the background but they arent doing much to my battery life... I dont use the power saver until it toggles at 15% battery life, I have vibration on, and my brightness is fixed at like 33% constantly... I have every ATT app disabled in the app thing.. I also have the "best Wi-Fi performance" thing ticked which says it might use more battery...
Yes, Gaming and watching videos on the thing is going to drain the battery out fast, Just like every smartphone I've ever owned... Its better than my GSM Nexus with the stock battery (Its roughly halfway between the stock battery and the extended one) and better than the S3 I had very briefly (However I will note the S3 couldnt keep a signal at all whereas my One X+ can...) The conversion seems to be that you trade about 2 hours standby time for 30 minutes of screen-on usage in my case
Picture 1 is me using my phone normally in a day.. 15.5 hours is more than enough (I'd say i get closer to 13 or 14 average) with 2.5 hours of screen on time
Picture 2 was me basically doing nothing but watching Youtube and playing games this morning... its really not all that bad, the biggest consumer/ battery hog for me is Mediaserver for some reason, I'm not actually 100% sure why (I know what it is...) or if i could pull even better battery life if there is something actually wrong with it and its draining my battery excessively... But I'm not complaining about it because well.. this was me abusing my phone pretty much
Not arguing that some folks are getting rubbish battery life, Because they are, I'm actually more curious as to whats causing it, There has to be something here and some way to fix it
Follow up to yesterday's battery
Ok in the attachment is my usage today. As you can see it is totally what I would expect from the phone. I got it to that point by disabling Google Now. That kind of stinks however, I can actually use my phone without being nearby an electrical outlet all the time. The other thing that works well is how much cooler it is to the touch under normal use. Normally it was quite hot. I work in a basement(3 bars with LTE) so my guess is Google Now was always trying to utilize location (even if it wasn't immediately obvious) on the screen via the indicator and thus would just kill my battery especially when I would pick it up to use it with the screen. I wish I could use Google Now but perhaps I can slowly bring back some of it's abilities and find a happy medium.
I'd also like to make note that I am still utilizing the power saving features for Jelly Bean along with JuiceDefender.
No offense but I cant read that battery thing you got. I cant see how long you used it or anything, all i can tell is your battery is at 70%...

Yeah my apologies, the timeline is on the X axis at the bottom. Unplugged at 7am, and at 2:32pm it was above 70%. Pretty drastic difference since normally the last week or so I've been hitting 70% at about 9am.

Sounds more in line with what im getting... Though i have Google Now on... Weird.. Very weird
GSam is a bit nicer and free FYI so you might wanna give it a look
how much playback time should I be getting for 720p mp4 files? My phone drains about 10% every 20 minutes with power save on, auto sync and all wireless radios off and minimum brightness, I am quite disappointed, is this normal drain?
I had to open my big mouth, Now my One X+ has developed a little problem It wont enter Deep Sleep so yeah... now the battery life isnt terribly great
You guys might wanna check that your phone is entering deep sleep and not getting held awake by something, because now im seeing similar drain to you guys...
Very new issue though, Weird... I uninstalled an app I felt might have caused it and ill see if that fixes it, Currently recharging my One X+ to reset the counters and everything...
According to BBM, It appears to be my Wi-Fi keeping the phone awake for some reason... Next step if the uninstallation doesnt fix things will be to disable Wi-Fi and see if that changes anything
The first week I had my 920 I was lucky if the battery was at or above 40% by 12 noon. The 920 is my 2nd phone line and I am using it mostly to learn WP8, to surf the web some and listen to a lot of podcasts, usually 6+ hours of them a day. The past 4 days the battery in the 920 is showing insane runtimes. It is currently 11:30pm and it has been off the charger since 8:00am, over 15 hours with overs 8 hours of audio podcast listening. The battery is currently reading 61%. I originally got the impression that LTE was killing the battery, but that is no longer the case.
I have a Share Plan with AT&T with 2 phones, a Galaxy Nexus (GSM model from Play Store) and a Lumia 920. I use my Nexus as my main phone line, to access GMail and Google Reader (a lot of Google Reader feeds). The Nexus has been off the charger the same period of time and is showing 41%.
For me wifi destroys my battery for some reason I get 15 hours with wi-fi on or 28 with it off
Interesting, mine will usually run for 24-30 hours before hitting 15%, including regular usage. 4G gives it a whack but generally I find similar to other phones, if low coverage it chews the battery
Reading all the doom and gloom of 4G LTE on various mobile phones, after my 1st weeks experience, I was expecting similar results going forward. But, after 2 weeks of use, the battery falls in line with the results you mention. And, with that I am not complaining.
same situation here.
It looks like the phone needs some days to warm up and get long lasting.
Also I see that wp8 is heavly optimized for background task in order to not consume a lot of battery eg: my phone lasts more than 2 days with light usage.
I listen to podcast for many hours and it doesnt affect the battery that much, in fact I'm surprised by it because I know audio playing takes a load on the cpu.
Mine.. overnight without charge or using the phone it drained from 100% down to 35%. BS
Two words: Background tasks.
Make sure you don't have unnecessary background tasks running. I have less than 5 and my battery runs more than 2 days easily.
How do you kill or monitor background tasks?
I had really good battery time of 19 hours the first day of installing the new firmware, then I enabled bluetooth again and it drains like crazy. its hit or miss but people seem to think that whatsapp drains battery. I personally would like to disable LTE (its really slow in my area) and just keep bluetooth that seems to give me 12+ hrs of battery.

You can block background tasks for 3rd party apps in Settings->Applications tab->Background tasks. There is no way to monitor these tasks because WP OS doesn't offer any such capability.
Unfortunately there is no easy way to block 1st party apps and if they are misbehaving (like sync something over and over), there is nothing you can do about it.
Turn on Battery Saver can also effectively kill all background tasks. But that's draconian. I still would like my smartphone do something in the background for me.
Don't forget, the biggest battery drain factor could be your cell phone signal. If you keep the phone in a fringe area, the cell radio will drain your battery very quickly while try to maintain communications with cell towers. This is outside the OS and you can't do anything about it.
I had a weird battery drain the day after the last upgrade. No apps running in the background BAR the movie that i had paused.. I lost 80% without using the phone in a 6 hour period (post charging). After a reboot it seems ok. Perhaps i should pause another movie to see if it happens again....
I must say that I have mine 2 days and the battery drains too fast... I dont know what to do .. Maybe because its new ? Some one can help me maybe ?

My battery is pretty inconsistent. MOST of the time it's awesome, and will last like 20-25 hours without needing to charge, but that just makes it especially jarring when every now and then I go to check my phone at 4 in the afternoon and it's at critical, and I have no idea what causes it.
Plus when it does die I have to put it on the charger for like 2 hours before it will let me turn it on.
I found interesting point in the battery life today, if the screen is off, the battery drain is in the range of 3-4% which is good, however, if the screen goes on the battery drops like 15% in just 25 minutes. After thinking I tried to set the screen sensitivity to normal and it solved my problem. I kept the screen on for more than 45 minutes and the battery went down almost 6% only which is good. I still have to test more to give a concrete evidence.

I usually run a battery discharge app Saturday night. Then a full recharge with the phone off. That usually gives me dependable battery life of about 12 hours a day for the entire week. If I forget and not run the discharger I notice it midways into the week when I only get about 8 hours out of it.
AT&T lumia920:
after updating my phone to the 1314 update, my battery life got worse.
I went from 14 hours per day to only 8 hours.
thanks nokia -_-
note: I was not experiencing any connectivity issues on my phone.
let's see how many people here actually have NFC on and Auto-Brightness on... lol
I used the sleep app last night after charging to 100%, and then I fell asleep with it on.
I woke up to find the sounds still going, and when I checked my phone worried that I killed the charge, I found it still had 92% left. That's impressive.
Hi all,
Got my 920 a few days ago, and while it's a beautiful phone, I'm finding the battery life to be awful.
I've only installed a few apps on it, otherwise it's vanilla. With WiFi and GPS off and only moderate Internet usage (mostly Facebook and IM+) i get a max of 10 hours out of it.
My Galaxy Note easily does twice that with the same usage.
Is there anything I need to check/look for, are there apps that show what's chewing through my battery so much?
I love the phone but that sort of battery life means it can never replace my Note as my main phone.
Thanks!
I should add, it's running the Portico update. No crashes or random reboots that I've seen.
I have only had mine for a few days, but I have found with all WP8 devices (and I have tried most) a hard reset made a difference to battery life. Annoying, but true it seems, well, true for me. I have no idea if it is a placebo but might be worth trying if you can be bothered.
For your info, I am getting good battery life on my 920.
You need to discharge and recharge the battery a few times before the battery life gets better. In about a week you should find the battery life improves.
It was the same for WP7 too..... The software will calibrate the battery over time.

I actually did a hard reset when I first got the phone home, out of habit really. I don't mind doing it again, but maybe I'll give the battery a few more days and see what happens.
Also check your background apps.
it'll get better
when I first got my lumia 920 the battery life was shorter than my old NL 900.. but after a week or so and after I did a deep cycle now the battery will easily last for 48 hours... in battery settings it usually shows 4-5 days :good:
battery life is hit or miss, some days you'll get wonderful battery life and others its horrible, I know that its hard to measure battery life because you just cant replicate the exact same usage everyday. I find it hard to believe that the galaxy s3 (basically the same hardware) has better battery life, battery is only 100 maH more.
I honestly believe its a operating system/ application issue, I believe that there are some applications that are cycling and wasting precious juice from the battery. better coded apps/ better OS control will really be a big deal in the next os upgrade.

I've found turning off background tasks which are not required makes a big difference on the battery. Each time I install a new app, I look at the background tasks and see that it doesn't get added. Only tasks I have running are weather and a news reader app.
Also, I will not allow location on apps that don't need to. Searching for location when an app opens also drains a battery somewhat.
That being said, with my use, I easily get 2+ days (48+ hrs) of battery life.
May be it have to be synced
In my opinion, one reason why this phone need the run in for the battery life is in the first few days it need to be synced with many clouds, facebook, facebook photo, nokia drive....etc. As this will make poor the battery life in the first run in. But after one week everything done, the battery life becomes better. Just guess.
I've also noticed that with bluetooth turned off I get substantial more life out of the battery(but I tend to forget to turn it on when getting in my car, then I dont get calls on my cars bluetooth). I agree with disabling push and do a manual poll on your email servers, I dont have facebook or any of that stuff on the phone. Im mainly on twitter and on my email.
from time to time I see the Location services running when I unlock the phone, I've disabled the location service on bing search but that still comes up from time to time. Like I mentioned before I think the OS has tons of pros and like any other OS in its "early stages"(I say this because windows mobile has been out for some time pre iOS and Android, but it will get better over time as the company realizes main stream OS are getting replaced as the go to home PC.
My experience with Nokia Phones is they need 1 or 2 weeks to get the full battery life....
The first 4-5 days they really have a horrible battery live.. But as I said it's getting better after 1-2 weeks...
BTW I'm really impressed with the battery life of my HTC 8S, I'm getting 2-3 days out of it with heavy usage...
My Lumia 920 achieves a little bit more than 1 day..
I've had the phone since it was released(when it really bad battery problems), I was going to go with the 8x but I really love the camera on the lumia 920.....
Ok for the past two days I've been using my phone with bluetooth off and i've been getting really good battery life, a friend of mine has a surface rt and he was having an issue with the battery depleting even when he left the device on sleep for hrs, he noticed that after disabling bluetooth the issue with the battery went away, this clearly points out an issue with the os and the handling of Bluetooth.
Surface RT and Lumia 920 have a totally different OS i don't think you can compare them that easy...
And it well known the Bluetooth deceases the battery life of every smartphone... It's the same with NFC (Tap&Send) and super sensitive touch or Wifi...
Just turn off the things you don't need...
My Samsung Note 10.1 tablet has no noticeable difference with Bluetooth on or off (that is, not actually using it, just having it enabled). It's using BT 4.0 which has very good power efficiency.
Any idea what revision of BT our Lumias have?
It also makes a difference if you switch your bluetooth on to be visible or not...
Ii is the same with Wifi you can activate to be notified when open networks are around... If you do so.. your wifi will use more power because it is constantly searching for new hotspots...
Well, it's been a few days & recharges, and it seems the battery is getting better.
Thanks for all the suggestions from everyone. I was severely disappointed with the initial battery life, and while it's getting better, I hope it keeps improving. Switching background data services such as push mail and chat makes sense when it comes to preserving battery of course, but so far from all the smartphones I've owned, this is the worst performing of all in terms of battery. I don't want to have to manually check mail or log in/out of chat, since that defeats the purpose of having a smartphone imho.
It's the only thing I have against the Lumia so far... even though WP8 is not as customisable as my Android phone, I certainly appreciate the design and how it works. I'll just keep crossing fingers for more battery conditioning
I think there is something like a help app from nokia on the phone...
You can disable the live tiles you don't use and the automatic xbox live sync service...
I wouldn't totally disable email sync... I just reduce the syncing interval...
If you have a lot of email accounts (maybe more) it even makes sense forwarding them all to a new email account and syncing all your emails
with this 1 account...
There are a lot of dirty little tricks to improve your battery life... Maybe every
single one don't make much difference... But all of them do...
With a lot of frustration, I have been experiencing high battery drain also, with the phone staying warm even while idle.
Following various comments, fixes, could be' on various forums, I hard reset my new, less than one week old, phone.
I was kind of annoyed, surprised it took a very long time to recover, with a picture of gears churning on the screen.
Finally it booted up with a message, reset or restore. Wasn't expecting the choice. I chose restore to see what's up.
There was an amazing amount of stuff to restore.
After restore completed, my phone was still having battery drain issues. I decided to check out what this back up and restore thing was.
Pardon me I never read the manual. No need to go into discussion of the process.
I then chose to disable back up and restore, soft reset, and boom. Battery usage is now at -2%/hr. instead of -12-20% idle.
Have any of you tried this?
