Not just another "battery issues" thread - Nokia Lumia 920

I have been meaning to post in here about how great my battery life has been, especially after seeing all of the threads complaining about it. I have been going home after a 9 hour day with 70-80% and even with extreme use, I have had no issues.
That being said, today my battery drained inexplicably fast for no reason. I checked my background apps and closed a few, but the battery drain persisted, so I rebooted.
Anyone else having this issue or know what causes it? This is the first incident I have had in almost a week. The last app I launched before this happened was Inrix traffic. Battery life has been beautiful, otherwise.

That's the fix I use. I now call my 920's battery life non-deterministic. It's great, except when it's not. When it's not, even if it looks like it should be because nothing is running, a reboot fixes it. Until the next time.
I would be shocked if there weren't an OS update to fix whatever process is going rouge and running away with the battery. Because it's something in the OS. Or at least its something the user cannot remedy, short of taking off and nuking the site from space.

I've noticed this a lot too. I killed a whole load of background apps and the battery life got a lot better. Then it got much worse again.
I believe my main problem is that I live in a low signal area. So I drain the whole thing in about 10-11 hours, even when out working the majority of the day.
One thing I have found is that the radios in the handset are very badly shielded compared to my previous handsets. This does mean that I can hear when the phone is sending out signals/utilising the radios. It does this a lot, even when it does have signal. It must consume a massive amount of power.

I get roughly 5-6 hours or so. Charger I bought on Amazon no longer does the trick (it's one that plugs into the cigerette lighter in your car and two USB outs). I have to bring with me the power cord and an inverter to keep it charged up so it makes it through the day.

I've got NFC and Bluetooth turned off, Wi-Fi on and the phone set to 3G mode. I get pretty solid battery life out of it.

When I feel the back of the phone getting warm, I reboot and it's good for awhile. I too would be surprised if there isn't an OS update to fix this issue.

I am heaving same issue with battery. Phone worked fine first 10 days and it started to be warm on the top back. Life of the battery can not last a day and i am a heavy user.
As somebody mentioned in comment to turn off this and that- i don't think so. I did not buy phone to keep everything off on it.

If in airplane mode. had couple pictures and few other things, this is what you get out of your battery.

Excellent. I'll just keep my phone in Airplane mode all the time! What was I thinking, leaving the cell radio on?

I've just had 2 great days life out of mine. Off charge at 6am and currently sat at 58% at 4pm. I've been streaming a podcast from the internet via bluetooth for 90 minutes and I've been tethering too, as well as all the usual stuff, so it's not like it's been sat idle all day. I've even been using Nokia Drive to get to work this morning (I teach at many different schools) whilst streaming media off the web and bluetoothing it to the stereo and it's not hit it bad. Seems very power conservative where internet streaming and GPS is concerned.
I have battery level for WP8 installed and it has a graph so you can see when the battery level is dropping off. I've noticed solid battery drain from running the Audible app which continues after the app is closed. Rebooting solves this. I have been working in an area with excellent signal recently though, that may have made a big difference. I get 9-10mbps on HSPA at the moment. I do, of course, have NFC turned off.
Hopefully Portico will be here soon and solve some of these power problems.

Am I the only one impressed by the SGS2's battery life?

After reading through so many threads about owners having issues with the battery life, I thought I'd start a happy thread!
I've had my SGS2 for almost two weeks now and I've always been happy with the battery life because it seemed to last a while.
I'm not up to the stage where i can just leave the phone alone (because I always want to play with it!), but I did an experiment 3 nights in a row to see how much power the phone drains in standby mode.
Each night, I'd charge my phone up to 100% and take it off the charger and then wake up to see how much power is remaining.
I left all the settings as-is and DID NOT turn anything off (eg 3G, etc).
The first night, I didnt touch my phone from 11pm and woke up at 7am to see that there was 97% battery left.
The second night, I left the phone alone at 11:30pm and woke up at 8am with 96%.
The third night, I slept at midnight and woke up at 8am to have 97% left.
If I average it out, it means that the phone on standby drains a lot less than 1% per hour. At that rate, the bettary seems like it can go with minimal use for at least two or three days. But it's something that I haven't been able to test just yet because I'm constantly surfing the net, testing out apps, etc during the day.
Admittedly, I don't have all that much installed on the phone that could possibly drain battery:
Friend Caster
Kakao
Whatsapp
Crazy Colours Live Wallpaper
Seekdroid
Official EBay
Battery Solo Widget
"Standard" clock
"Applications Running" widget
(I've got more applications, but the ones listed above are the ones that might have some sort of network connection and/or widgets that may need to update during the night).
I'm also using stock Vodafone Australia firmware in Melbourne city (in Australia):
Baseband: I900TDUKF4
Kernel Version: 2.6.35.7-I9100TDUKF4-CL331615
Build Number: GINGERBREAD.DUKF4
Does anyone else get battery life like this?
I'm not sure how big a role the network plays in these stats because I'm based in the centre of a major city.
As much as I hate the Vodafone bloatware, I've been reluctant to flash other firmwares like I did on my previous HTC Aria/HTCHD2/HTCDiamond because this one works so well with the battery.
3% battery over night ?. I get under 10%, with all off what can be off, with no funky widgets, no data, no wifi, no nothing. Still phone wakes up in the night for unkown reason and 80% of battery is taken by mysterious Android OS process.
I had Optus bloatware and I kept it for a week or two. I wasn't unhappy with the battery life but wanted to customise it and get root.
After flashing Lite'ning it was obvious how much less battery drain there was. I have since moved to Cognition and I am very happy with how it's going. I charge nightly, but I've never had the battery drop below 50%, and I do use the phone quite a lot. I wouldn't say I'm a heavy user (it's all so subjective) but I would have to be at least medium if not more.
I also love the Black Theme by Nitrozk and Pele, which is why I moved from Lite'ning to Cognition to begin with.

That is a problem with the 2.3.3 firmware mate. Best switch to 2.3.4 ASAP!
To answer your question, yes, I'm hugely impressed by the battery life.
Here's my latest and I'm still at 15%. I'm bone stock on KF3 with all the syncs set to every three hours and using Exchange push.
People blame everything (Wi-Fi Sharing, AOS) for their issues except what they do to their individual phone. Network signal strength plays a big role so does the individual router used for Wi-Fi access. But outside of that there's no other explanation other than individual configuration when identical phone's from the factory get such different results.
I don't participate in battery threads because they're pointless. Dozens of different people using the phone differently with different apps and settings on different carriers all talk in circles when there's no common basis for a legitimate discussion.
I'd call 3% overnight something impressive.
I'll try it out tonight.
I'm running 2.3.3 (No updates avaliable here in Brazil) and i'm not about to root it now. I'm getting a generic 7" tablet to mess around and learn how to do it properly.
So i'll be running minimalistic UI, Snowstorm, Battery Monitor Widget Pro on the desktop, with 2 screens.
HSPA+, bluetooth and wifi disabled.
Let's see how it turns out tomorow morning.
One thing i wanted was to flash in Samsung's oficial fw for Brazil, mine's a carrier customized one, and that's sort of pissing me off since i wanted to uninstall 75% of the garbage Claro has installed here.

I agree with you BarryH... having put the great battery stats in the first post, I wouldn't expect anywhere near that sort of level had I been playing with the phone or I had a thousand apps that run constantly in the background.
Having said that, it seems that there are the people who do have legitimate problems and then there are the people who simply have unrealistic expections of the battery in such a powerful phone. Kinda like buying a big truck expecting it to run on the same amount of fuel as a little car.

Let me know how you go Unreal... I saw on a thread a couple of weeks ago (not sure exactly which one now because there's so many of these "bad battery" threads) that someone had said that their phone lasted more than three days with minimal use.. and noone believed him! lol
How strange, I was about to make a similar thread. I had just gotten 3 and a half days out of my battery earlier tonight, no connection to charger since friday night. Minimal use of course, few phone calls and general tinkering, but still impressed with the standby. It was at 1% battery left so time to charge her up again. I charged my phone till the 100% alert came up, then charged it for another 45 minutes as I heard it stops it dropping immediately to 95% as some others have experienced. I've experienced similar too.
So after unplugging it, I pressed the power button to turn the screen off and haven't touched the phone till just now, about 6 and a half hours later. I pressed the power button and battery widget shows me 98% on the battery. If i was to leave the phone completely in standby and not use it, at about 1% drain per 3 and a quarter hours, that's about 13 and a half days standby!
I'm on 2.3.3 btw.
2-3% overnight drain is along the lines of what I get with KE2 and KF3. Data off, 2G. I get about 20-30% of drain a day, 30 mins usage, 30 mins talk.
I get great battery life on mine, although I have not made a valid experiment using quatitative data
Hopefully, this will be the NEW TREND for all the Android Gingerbread dual core phones.

We have one guy who went five days supposedly. The majority of posts in that thread are just like ours, a combination of moaning and pleased. It all comes down to how the phone is used and what's loaded on it.

Im very happy with battery life. Froze a couple of apps and I was good to go.
First phone I've had that didn't need to.be flashed on a daily basis.
I think anyone that's needs more than a day from a single charge needs a blackberry or a home to charge daily.

I have owned a lot of androids and my sgs2 has the best battery life.
I guess you think it's ok, probably because coming from another android phone, it is.
For me is a pain, every half day have to think about charging, my whole usage of this phone although brilliant, has been taken over by thoughts of how I'm going to next get it charged aposed to what I want to do with my phone.
Something I didn't expect was just how much this phone discharges whilst playing music with the screen off.

Im not impressed, it just met my expectation coming from an SGS1, but the first one impressed me so ergo Im also impressed on the SGS2
I have had this phone since pretty much near release date. I have been and still am very impressed,by the battery life.
I'm currently on KG1 2.3.4, but since before this past Saturday I was always on 2.3.3 (KE2). Even on 2.3.3 with the AOS bug I was still very happy with battery life.
Now with KG2 out, I'm sure ill be even way more impressed.
I love this phone, and I have been a religous iphone user previously too!

On my phone with 3500mAh battery. With yellow arrows, the behaivour during night.
KG1: during 4 days ( no drain at all)
KG2: during one night
I must agree, this is my 3rd Android phone (out of a total of 37 phones since 1990) and it's by far the best battery of any smart phone.
My best battery usage is 3 days 13 hours with 25% battery left. That was with wifi on all the time, over an hour of screen time (I was working at home, so no need to play with the phone) and over an hour of phone calls. I'm sure it would have reached 5 days. BTW, I'm running 5 pages of widgets, firefiles wallpaper and GMail is updating all the time.
During the 3 days time I switched off 3G as this is the biggest battery drainer I have seen. I live in a 40 floor tower which is made of thick concrete and the 3G signal in my home office is terrible, the phone is constantly hunting for 3G. When I'm at home, I don't need 3G as I'm using Wifi.

[Q] Need help figuring out battery drain

Hi everyone, I'm relatively new to using android devices, i've played with some of the devices my friends own as well as a tablet my brother owns but this is my first personal device.
Anyways, I've had the phone for around 3 days now? It's going great but I feel like the battery is draining a bit fast and I'm not sure if I'm "normal" by standards or if my phone is slightly problematic.
I've attached the two screen shots below
Man things I do on my phone are Gmail, Push email for work, browsing, WhatsApp, Gchat and occasionally music and maybe 20-30 minutes of video.
As you can see from the graph there were two very short moments where I was charging the battery as well due to transferring some files. Finally, I've had a chance to completely drain the battery once but haven't had a chance to do one of those long charges people talk about but have through multiple charging occasions gotten it to 100, although right when I unplug it it goes to 99%.
Thanks!
EDIT: My phone wakes up quite a lot I think because I quite a few work emails a day, around 80-100 in addition to another 20 or so gmail emails a day. Thanks.
I have my own problems about the battery life too. Specially on standby mode all turned off (wifi,sync,gps,data,etc) 93% when I sleep then when I woke up battery goes down to 80%
are you too experiencing this as well?
haven't tried that yet, I attributed my battery drain to email, could be another problem then.
Start with Better Battery Stats from the market and look for wakelocks .
jje
There are a few posts on battery issues.
I too had battery issues and in my case it was a couple of things.
I put the screen onto auto brightness and put wifi onto off when phone asleep.
These 2 things fixed my totally. I know lots of other people are having issues and its neither of these things but these are what helped me.
I also got an app to stop apps starting up. There are a suprising amount of apps that start when your phone starts up that you dont need to be running.
I think having wifi on constantly and getting 19 hours out of a charge is darn good for android.

I have experienced this after about a week of use. I left the phone when it was 95% and after an hour in stand by, it drops to the 80 something mark, b/w 84-86% any more people who experienced this?

Yup, I had WiFi on pretty much on at home and at work and it certain does chew through your battery! Started at 7am at 100%, back home by 8.30pm and at 20-30%. By 10-11pm, it's on charge again.
Usage is fairly average, x2 30 mins of music to and from work, emails on push, send and receive texts, a couple of calls here and there.
I didn't save snapshots of some tests I carried out, but I'll try to recreate the situations again and upload them.
It seems if you have your WiFi settings, Keep on during sleep to Always, it's constantly draining your battery, even if your handset is on standby. I've left mine to Never, but have found only a small improvement to battery life.
Attached is my current usage WITHOUT WiFi as much as possible, there are a few power spikes where I've had to use WiFi and to connect to PC to transfer some documents, download some Apps. Also I'm NOT at work for the last two days, so usage has drastically dropped. Loooking good at 2D 1H 50M, battery at 45%
You can see for most of the first day where I haven't used WiFi there is a slow, but steady drop, the first major drop was when I was playing a game on the way home, then it's steady again. The biggest drop was when I used WiFi to download the odd app or two, then I turned it off again.
Hope this helps the OP in answering some questions about finding out what is draining the battery.

[Q] Battery Life?

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!

GSM-Modul eating battery

My lumia 920 worked for about 48 hours dropping battery to 70% then i went to work where the signal for my provider is very weak and it dropped the hole 70% to Zero in about hours. has anyone experienced that or just better has anyone a solution for this?
Have you checked what apps are running in the background? It's likely not the radio causing your drain.

for me it seems to be the radio what's eating the battery
I nearly uninstalled everything and put the phone to batterysavingmode. So it was unplugged from power Saturday in the morning and till monday noon it used nothin more than 26% of battery while listening to music surfing, checking mails and making some calls. Then i went to work and i did nearly nothing with it. at 9 o'clock the battery was dead.
No whatsapp or anything else on the phone
Also I encountered this problem with my NL920 but it's not all the time encounterwed; very strange...
Yeah, definite link between poor reception and poor battery life on my device, too. Hopefully we'll see a fix in the meantime, use WiFi where you can though, it helps me a lot.
This is normal. Every phone is like this. When the signal is poor, the phone must consume more electricity in order to maintain the connection. I think Nokia designs their phones to stay connected at all cost though because they're famous for having good reception haha

Crazy Battery Life on 920

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 ?

don't judge a phone's battery life until a week later.

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.

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.
