I cant tell if it's always been like this. Or if this actually isn't normal because I'm always concern with battery life. Im a very heavy user in the sense my phone will be on and im texting, xda, social apps i.e google +, email check every hr, and twitter.
However, i started feeling like my battery has been draining alot faster when the screen is on. I have no problem with the phone sleeping. I was experience this on Calk rom and now acs ics rom. I literally can look at my battery percentage drop 10% in like a half hour. Is this normal if screen is on the whole time? I've used better battery stats and system panel I can't find anything causing the drain. I see the suspend and events but doesn't that effect the phone sleeping?

Are you on the new modem? Looks like you have weak a signal. EG31 might help a little if your not on it already. I used the full EG31 tar right when it dropped and have been getting great battery life (it may be to early but so far so good)

not sure if its going to work but hoping it does thanks for the response still
turn your display down to under 50% you won't see a difference except outside in daylight and kill this app every time you reboot the phone hit Settings>Applications>Running services then hit DRM content > stop > ok
I get over a day on one charge.

Ok ill try the drm content stop..however my display brightness is already down at like 10%.
Also, kill the Social Hub as well, that drains the battery significantly.
You might try one of several roms available in dev. They address most of the aforementioned issues.

The biggest battery drain reason is the location by wireless network option. Make sure its unchecked. Ever since I did that, my battery life has been awesome. I get to keep my brightness high, Bluetooth on, etc...

All the basics (brightness and all that stuff) on top of the stuff you have running. The darn task killer/manager I see in the icon top left of your screenshot is a HOG on resources check the caching... You can literally **** with these phones for half a day to set it up the right way to conserve. I think wireless is hogging too but I am talking primarily about the first part of your rapid loss, the left part of the graph so to speak.

I purchased an extended battery and was still getting crappy battery life. SpareParts always FC'd on me... but last night I found Badass Battery Monitor in the market and in my opinion it's even better than SpareParts!
It helped me find that the Hotmail app was keeping my phone awake for almost an hour every day even though I had it set to download email only once a day. Removed that right away.
Plus it gives a great % readout in notification of the battery level. I think it's a fairly new app, but it really is worth checking out especially if you're having battery drain problems.
Just killing Social Hub has increased my battery life significantly. I'm at 11 hours now on battery, with 62% left. This is from last night when I unplugged the phone at 100%.

I'm on the Sydnicate Rom there isn't even no social hubb app. He has alot of the mods like noCiq and everything. My phone sleeps well its just when I start using it I can see it basically draining like 10% every half hour. I'm a heavy user I know my phone will drain fast while I'm on it I just would expect it to last 8-10 hours on heavy use.
Right NOW:
I'm at 4 hours 12 mins 22 secs at 37% left.
Display Time is 50% 2 hrs 41 mins 51s (Brightness is set all the way down)
Android OS 10%
So I'm assuming in 2 more hours my phone will die. If this is just normal for a heavy user then I guess I have to deal with it?
I was very disappointed with my Epic Touch when I first got it. I was getting a dead battery in about 6 to 8 hours no matter what I did or did not do.
Calibrating the battery seems to have fixed it.
I'm at 73% battery with 8:32 hours up time and I've made about 12 calls ranging from 2 to 10 minutes.
I've also checked voice mails, emails and other stuff.
I just charged the battery til it was full, plugged and repeated until it stayed at 10%, popped into CWM5 and cleared the battery data and then used Battery Calibration from the market (free) and it's like a got a battery upgrade!
As far as wake lock issues, I've not having any of those. I took my charger off the phone around 3:30am this morning (100% charge) and when I left for work at 6:50am, I had 98% battery still.
When I got to work it was down to 96%, I checked my email on the drive there.
I'm trying this out, wish me luck.
There doesn't seem to be any possible way to charge my battery to 100%, unplug it and not have it immediately drop to 99%.

If those screens are both from the same charge, I see nothing wrong with your phone.
you have 17% left, and you have 2.5 hours of screen on time. So you're on target to get just over 3 hours of on screeen time which is completely in the norm for these phones. AND you're over 12 hours. I don't understand what else you could ask for?
People get all caught up on total charge time, but, to be honest, it's completely IRRELEVENT.
If I dont use my phone I'll get easily over 48 hours out of the phone... Screen on time is what matters. And from a full charge, if I were to use my phone for 4 straight hours without stopping, it would be about dead. When the screen is on, you're using the phone, and the display is the biggest battery suck out there. When I do all the tricks to conserve battery, and I set it up right, I get 4 hours screen on time, which is pretty incredible with these phones.
Now, If you WANT to get better then you have right now, a few things are coming into play.
1) Your signal is weak, this will suck power no matter what more then it should, so get better signal if you want some more time out of your phone.
2) If you installed a new rom, and you didn't calibrate your battery properly, you're losing battery life.
to calibrate properly:
a) download battery callibration app from market
b) charge to 100%
c) unplug battery charger and REPLUG IN and wait for 100%
d) repeat step c a couple times
e) while plugged in hit the calibrate battery button in the app
f) unplug phone and use til dead and recharge
This will yeild you the best battery life.
3) De-Theme. Although I use a theme, every theme I've tested, for one reason or another, drains my battery faster then running the stock phone theme.
4) If you haven't done the basic battery saving things, you should do them to help yourself out. Here's a few I use.
a) Turn off background data, you only need it on to use market
b) Turn off, or set sync for all email and social apps at as long intervals as possible
c) dont use any widgets
d) download watchdog lite so you can see when apps are acting up and using extra battery
e) when you're done using your phone, open task manager, kill all apps, and clear memory
f) always leave the brightness off automatic and as low as possible
g) download SETCPU and run your phone at 800mhz, and undervolt as much as possible (50mv most all phone can take)
h) use black or dark wallpapers, on LED screens back means the pixel is off which uses less battery
G will be your biggest battery save. I've also tried using the SUPERFREEZE thing in the dev section and, besides in sleep mode, I saw no adverse effect. If you wanna kill socialhub, fine, but I dont see any noticable difference on my phone with it off.
If you do all these I promise you'll get better battery life.
Wow, I did a proper calibration today and I'm getting great results already. I've calibrated before but I never had cleared stats in CWM or did the unplug then replug charging thing.
Anyways, I after 12 hours I'm still at 35%! The longest I've ever gone before is 12.5 hours. Screen on time = 1 hour 30 min, but some of that was a battery intensive game (puzzle quest 2). Also i'm running calk's rom, so i'm sure that helped.
Thanks kdoggy, i didn't expect to see results this great.
Those are good tips too Jermzz, thanks!

Wondering if anyone else has had any battery issues? I went to sleep last night with about 85% or more battery, and 5.5 hours later my phone was dead....when i plugged it in for like 5 minutes to call my work and tell them i was going to be late...when i got to work my phone said 45% phone idle and 45% cell standby for battery use
none here - took phone off charger about midnight, this morning after alarm rang for the full 10 minutes, it still showed 100%
i've been watching it and am really impressed with battery life - is it possible you've got a program running in the background? - i had Startup Auditor to stop apps in the background but had that from before, on my Vibrant
on the vibrant,running a predominantly black wallpaper, screen brightness at 13%, putting phone in "airplane mode" when i sleep, keeping GPS off, data sync off etc, it'd be down to 17-22% at end of day before going back on charger
this G2, running live wallpaper (thunderstorm), no efficiency moves (ie GPS off, etc), screen brightness at 50%, phone still had 34% last night before going back on the charger - and the battery has not "conditioned" - i noticed on the past 2 phones batteries life got better after the first few weeks of use.
Nothing different than my nexus...and i was thinking maybe it was a game but that should have been killed automatically and i dont think it would say phone standby and cell idle if it was an app would it?
tonite you might try putting the phone in airplane mode when you go to bed, and turn off GPS
see what happens to battery drain overnite - if it diminishes then i'd look at what apps you've installed. there was an article on engadget not too long ago that some researchers had analyzed the 358 most popular apps, and found 30 were reporting data to their "mothership" that had not declared it or asked for permission to report data.
hope that helps
well another weird thing is, that when i bought the phone and brought it home, usually it comes with half battery and thats what it showed but i had to charge it quick with no apps really installed on it yet...Im charging now and will test to see what happens with battery...i just removed off alot of my apps.... to see whats up
I'm getting about 10 hours with regular usage though I wish I knew why Photobucket keeps starting everytime i kill it.
I hope you guys charged the phone fully before you used it first. That can play a big role in battery life.
I got my phone yesterday and haven't done any calibrations yet. I've been playing with it like you normally would if you buy a new smartphone. I took it off the charger around 9pm last night and at 7:32am right now I have about 60% left. So roughly 10.5 hours later and I've only lost about 40%. I'm very impressed by that. My vibrant would have been dead by now, it rarely lasts through the night if its not on the charger.

What's your time with out signal, sounds like the 50% bug to me, google the airplane mode fix, if not you might want to look into a new radio, and you should allways recal your battery after you flash

So like everyone else my battery life sucks. No big deal. I bought the extended battery from Sprint, and I can see the battery diminish in front of my eyes. I mean dropping 1 percent per minute. Is there a way to test the phone to see if it is the culprit?
Sent from my PC36100
ther are lots of ways to check things. does it drop 1% a minute all the time meaning you only get 100 minutes? does it only do it when you take it off the charger at 100% where ti will drop to any where from 99-90% in a matter of minutes?
if the later then thats normal and is because the phone doesnt have a trickle charge. this means that the phone charges your battery to 100% then stops however the indicator on the phone will not change it will still show 100% once the acctual power reaches 90% the phone then charges again up to 100%. what this means is once you take your phone off the pwoer if it has been sitting there even if it says it is at 1005 it can be any where from 90-100% which the battery quickly changes to over first few minutes.
If it happens past 90% and all the time then something is wrong and you likely have at least 1 if not more apps running wild on you, you have things set to sync constantly, and you have everything under the sun turned on for your phone.
for apps the paid version of system panel is very nice for monitoring you can go to monitor top and top apps and see which apps are using the most battery/cpu.
witht he information you have given that is aobut the best i can tell you. I would not say everyone has crappy battery life with the evo as i have slowly gotten my phone set up and now with moderate usage i can get 14-15 hours and at least 8-10 with very heavy usage(stock battery) which i dont consider to be crappy battery life.
I appreciate the response, and I forgot to add that I'm running stock unrooted sense. This is not my first Android phone so I know about battery managing. I don't have everything sync every two minutes nor do I have everything turned on. It does drop rather quick even past 90 percent. I think it might be the phone it self. I doubt I got 2 bad batteries, one being extended. I'll see if I could get a device swapped out.
Sent from my PC36100
My first EVO was like that. It drained quickly shortly after charging. I could never figure it out. Till one night before going to bed, I noticed something weird about the bottom keys on the phone. They were " very dimmly " lit. The home, menu, return, search were all dimmly lit. It was I believe a defect in the phone. I got it swapped out. No problems like the 1% drain since then.
I have had my Nexus for almost two months now and the battery life on it... well I get maybe two hours of usage on it (screen on, auto brightness) and i came from an iPhone which gave like 5 on full brightness.
All the reviews I read about the phone talked about great battery but really... When i get home everyday the battery is almost dead and i'm talking light usage.
This does not sound normal. I'm on a GSM nexus and I can typically get close to 4 hours of screen on time without trying too hard. On a typical day, I go to bed with about 50% left. Check the battery stats in settings and see if your phone is constantly awake. Sometimes rouge apps can do that. Sitting in a dead zone can also use up battery quickly. Its possible you have a bad battery, but I bet something else is causing poor battery life.

That is dependent on a lot of variables. You could be listening to a lot of music, preventing the phone to go in deep sleep, an app could cause a wakelock, preventing it again to go to deep sleep, are you on Stock? Do you use a dark or a white wallpaper, are you in an area with bad phone reception etc. etc.
If you could give us some more info (preferrably screenshots) we might be able to help you. Screenshots of the battery usage during the day, the apps that consume most, the diagram which states how battery usage is combined with network reception etc.
Besides that you could install CPU SPY to see how much your phone spends in deepsleep. If that isn't looking well you could install betterbatterystats to find out if there is an app causing a wakelock.
I don't listen to much music and have a black background. It is running stock 4.0.1 and for about half my day I have no service but the phone is in airplane mode at that time so it doesn't kill the battery using the radios.
I'll update with screenshots of normal usage
guys i want to know if the battery life of your lumia 900 is good? mine sucks, I got the phone about 10 days ago, I find the battery drains very fast. normally the first 3-4 hours are good, but then it will drop like 20% within 30 minutes, then drains very fast, after around 10 hours it's only 20%ish. I use the phone in normal way, check emails as they arrive (about 20 emails a day), text 10-20, phone call 20-30mins, that's all.
I live in UK. first time I launch Nokia Music it stopped response, I had to reset my phone for it to work properly.
is this normal? what should I do to improve the battery life?
I found the battery life alot better on the 900 than my Titan and Lumia 800, I have 2 email accounts on sync every 15 mins and just a weather app running in background, I have tried hard to run the battery out in a day of heavy use and just managed it, It can depend greatly on how strong your signal is from your Network provider as if it has to struggle to find 3G or keep switching then this will drain the battery more, Maybe change email sync to either every 15 min or 30 min to see if that helps, Screen time-out at 30 secs and dark theme can also help conserve power, Check background tasks in settings and switch off unnecessary apps, Also a new battery will need several charges/discharges before it reaches its optimum capacity, Try not to run the battery out completely, Normally just after you get the low battery warning is best then charge overnight.

thanks for the tips mate. i've changed the sync to every 15mins. I also manual input apn option and turn of the location service. hope this will help...
Are you connected to a MicroCell anytime during the day. They are known to drain battery quickly. I have a lot more running than you (email & background) and my average "screen off" drain is about 3.5% per hour, or 56% per 16 hour day. That leaves me about 4 hours of screen on time before my battery is nearly drained (screen on/data/calls drains another 9-10% per hour). Pretty impressed with my battery actually.

How do you guys measure the % drain per hour on the lumia? I know android does like a graph and stuff is there an app for it?
I have
Four email sync
Twitter
facebook
weather app
and take photos
and a few calls.
lasts me anything between `12 hours - heavy use to around 19 hours of mild to normal use and am actually quiet impressed with the battery.
Suggestions :
Turn off WIFI when not in use as it uses power to search for signal
Poor Network coverage will DRAIN battery as well.
Disable any Background tasks which you do not need.
And I charge my phone every night regardless of the battery percentage even if its 50% left
Search feature of the forumn... is it good?
thread in this forum all about battery life.
If you are in a known WiFi area, like home or work, no need to turn off WiFi. Uses less power for data transfer than LTE, but of course, may be a bit slower. Out and about and have your screen on a lot; might be a good idea to turn of WiFi. WiFi uses almost 0 power when your phone is sleeping.
Just finished a series of Background Task tests. Comparing drain with tasks enabled/disabled. About 0.5% per hour or 8% per 16 hour day. That's with 8 tasks running; USA Today, Fox News, Weather Channel, Mehdoh, Urban Dictionary, Network Dashboard, Clever-To-Do and Battery Meter. Btw, Battery Meter is a homebrew app, but you can check percentages on the Settings>Battery Saver screen.

I do know about the diagonistic mode... but uninstalled it as there are rumours it eats battery as well
Why would the Diagnostic App, which can't be uninstalled, as its part of your ROM, have anything to do with draining your battery. How do these rumors start. Guess this is another "truth" I will have to prove. Running a series of articles on Mobility Digest to squash all these urban legends. So far, push email, battery saver and background tasks. More to follow.

I don't think it does, I loaded it up yesterday to check what my battery drain was, since then my phone has used 27% in 22 hours. Perhaps it uses a lot of power while you're using it, but surely not just by having it installed.

It can be uninstalled as I have installed and uninstalled it quiet a few times now, probably it on a hidden partition of the ROM, but you can remove it.
Just for the sake of it I kept it all day today and my battery life was not affected as such,, so rumours are rumours after all
No, all you are doing is making it visible or invisible. Its always there. Do you actually see it installing like a Marketplace app, or does it just magically appear when you type in ##634# (or whatever it is). Oh, never mind.

Got the phone brand new yesterday so below are the first discharge stats with wifi ON only and cellular data off and max speed set to edge.
Remaining battery: 57%
Time since last charge 7 hours.
I've been playing with it from time to time since I unplugged it. 2 emails fetching every 15 minutes, whatsapp, downloading and testing apps.
How does it rank for a first discharge?
Difficult to say. The first thing you should do is dial ##634# on the phone keypad which installs the diagnostic app, then you can check the battery discharge rate. It usually jumps around for a few seconds and then settles down to around 90mA - 110mA. If it's higher than this, something is draining the battery.
I'm finding that sometimes various apps seem to start up some sort of process that continues to drain the battery even when it's not doing anything, and the best thing to do in that case is a soft reset.
Doing this I managed 60 hours between the last two charges, and since then I've gone 80 hours with 29% still left. That's with very light use and no apps installed though.

My drain reads around 100ma so I guess I'm good.
i'm not getting good usage with the battery now, on my 3rd charge, and so far only able to last 1 day, and i'm not even consider as a heavy user, no text, only few whatsapp (around 10) 15-20min calls and little browsing and market downloads. i didn't even on the auto update for emails... hope that the battery will improve after a few more charge...
I have had this phone for about 2 weeks, and the battery life has been great. However, today, my battery jumped to 90% within 6 minutes! I was doing nothing different today than I have been. Why has my battery suddenly gotten to be so terrible? What can I do about it? How can I tell the health of the battery? I have attached a picture.
I also calibrated the battery within the first week that I had the device
From what I understand about li-ion batteries, the top 10% charge is usually not accurate. Since it's not good to fill li-ion batteries to the max, they're set to display 100% when they're not actually a 100% (since people would complain that it's not charging fully).
Here's some info about these batteries http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries/
As for your specific issue, I've heard there's a problem with the idle (a lot of ROMs claim to have that fixed). As for helping save battery life, if you idle then looking into JuiceDefender is a good idea. JuiceDefender combined with FreeSG3 ROM have helped me get at least 4 hrs of extra battery.
I completely agree with what you said. Now, in just 45 minutes, my phone has 82% battery left. My phone says that it has been in use for the last 30 minutes, but I haven't touched it - the screen has only been on for 15 minutes total. Does the battery drain seem a bit excessive?

So I think I see where part of the problem is. Sprint Automatic Connections Optimizer turned Wi-Fi on. I am at my house, but it wouldn't connect to our home Wi-Fi at all. It knows the network and the key, so why wouldn't it connect?
Hmm that's weird... I've had some problems with the Wifi at home too, but so does my Linux machine.. so I think it's something with the router and not the devices themselves. On mine JuiceDefender takes care of it though... if it doesn't connect within a specified amount of time it turns it off and tries again later.

Running stock with no root yet on my Spring Samsung Galaxy SIII I know that I had my % being displayed when charging my battery and the light went "green" pretty much as soon as it hit 90%. When I unplugged the device it showed 100% for a brief moment and then quickly came down to the 90% that I thought it should have been at all along. Did you have it charging for a long time after it turned "green" or did you just take the device off as soon as it changed from red to green on the indicator light? I still have good overall charge times it is just the top few percent that are kind of wonky.
Hope it helps as a possible reason why that happened to you. I know when I wake up and have had it charging overnight it tends to stay near the 100 mark a lot longer still as well.
I'm happy as can be! I use CM10 nightly and KT747 kernel w/stock battery and I'm a pretty heavy user, no games on these stats but definitely suggest this setup for anyone that's having issues w/ battery. Also the fastest.. Literally secs to open web pages and flies through everything..
To see what's keeping your device awake, open terminal emulator & type: su (push enter) type dumpsys alarm (press enter) this will give you a list of what's waking your device. I use better battery stats app which there's also a forum on here for that's a great reference. Sounds to me like you should drain it to 0% and charge back up. This should solve any calibration issues you may or may not have. What's your signal like where you've been getting mass drainage? That does play a large roll in drain as well..
