Hello,
I recently got my nexus, and rooted only two days after receiving it. I installed cyanogen's latest. I am getting low battery; in only 5 or so minutes, the percentage goes down by at least 2 percent (while using). I looked to see what may have been draining the battery, and found that the display alone was using 62% to 75% of my battery. I tried undervolting, but the display seemed to still be in the same draining range...
Is this a hardware related problem, or is this a common nexus thing?

same here, really starting to piss me off when i see people talking about 70% battery at the end of the day while my phone dies in 6 hours
Cyan?
Woah, I think this might actually be cyan's Rom.
I flash enomther's rom and i got display percentage at around 15-16% ...
I think cyan will look into this soon enough...
But for now... I guess I'm gonna wipe... :/ and stick to enom's or some other ROM...

C´mon....see my signature!
More than 10h now, Wifi on all the time -> 70% battery
This is not that bad

I think the problem is only with a few people, but I know others are experiencing this. This might be something with the "latest" nexi. But idk, it's a mutual issue, a fix should be coming
Probably you are right...
But, I would like to know, what settings peolple use: like updating wheater every hour, emails, widgets,..ham many apps are running and so on, ... perhaps connected to...sometimes people dont even know that
Edit: I got my Nex in january.
The change in the display usage percentage is just due to the way the powermanager works. Its not using more battery, its just displaying how much power it is using more accurately.
have the same problem.
100% airplane mode ON no WIFI, in 5 hours 72% battery remains . (PHONE IDLE took most of this - my G1 could go 1 month with this settings)
IN 12 hours in was 6% and with LOW use of my N1.
Yesterday I removed numbers in my battery and it was a litle better, not much but a little. (about 8% better)
I had 5.0.5.1, 2 and 3 and everyone had the same problem!
CM please take a look at this. What do you need any LOG info or something!
Have you tried wiping battery stats, then charging to 100% with it off, then booting into recovery and wiping battery stats again, then charging to 100%? The few times I've had battery issues that's taken care of it for me.
I flashed cyan again with a wipe (again), but got the same thing.
On enom's rom, I get beastly battery. I think we just have to wait for a fix for the people who are affected.

Do you need root to wipe battery stats? how do you do it?
Well I did the wipe battery about 3 times and in OS it was already green light 93% full.
I WIPED and put the power in on NON POWERED PHONE. It took 1 hour more to come to the green light . than I wiped again and went to boot up.
at 11PM i had 100% battery went into airplane mode wifi OFF.
And i did one other thing. Some of you had the battery drain issue with trackball wake. So I disable it.
7 hours of this and I got 97% - beautiful
before that I had 72% so there is a difference.
Now I have to see if the wakeup trackball is the cause of this or the wiping the battery stats.
Will eliminate one and other and keep you posted
I took my phone off the charger at 4:30am and the next day at 5:30 am i had 12% battery left. i used my phone a total of 3 times. most of the time it was on standby. i have setcpu with my phone UV and UC to try to save battery with profiles set up. in battery information 85% of the phones battery went to cell standby. Any suggestions on how to improve this?
Try wakeup trackball OFF in spare parts and battery % OFF in upper taskbar.
I have now from 100% to 59% in 7 hours. wifi ON all the time.
I have tried to wipe battery settings and charge fully with the phone off, but after the full procedure, I still get the same end result. I attached a picture of my battery usage.
Im pretty sure i saw a post online about the newer nexus's that were released having a better display. If this is true then wouldn't the phone's hardware alone be using more battery?
I can confirm I am having the same problem. I wasn't sure until I checked battery usage overnight. It used to be that with my phone on airplane mode I would use about 2% while I slept. Now, it's 9 or 10% with "Phone Idle" taking the lion's share of it.
I have tried deleting batterystats.bin after a full charge; powering off (while on charger); charging up to full again, but this has not solved the problem.
A few notes:
When the phone is idle (but not in airplane mode) it uses about 1.5% per hour (compared to about 1.1% in airplane mode)
I am using setcpu profiles to keep cpu usage right down when idle
Around the same time I upgraded to 5.0.5.3 I also started using the himem version of fastboot. And yes, if you suspect I don't know what I'm talking about here, you are quite right
For my next trick, I will try resetting battery statistics via recovery. What fun!
I've kept the cyan rom, and changed some settings to increase battery life. I turned off the battery percentage icon, and turned off the trackball to wake. I still got that the display was using a lot, but the battery still lasted pretty good. I guess there isn't too big of a problem on my side. It probably is the "newer displays" on the "newer" nexi. Maybe there really isnt a big problem
I changed now from CM to Enomther's TheOfficial Nexus1 1.8.1 and battery now works great.
I unplugged the charger at 12.00 am at midnight and with quite good use, not extremely havey but a good use I had 30% battery left at 20:00 (08:00PM) that day.
I lost only 2% from midnight to 7:00AM in my airplane mode and with Gmail check 10 min of phone calls wifi ON all the time checking web pages and showing off my live wallpapper at my work I had at noon (12.00PM) 70% battery left!
I LIKE IT!
now I'm thinking to push Kernel - .32 & .33 to see if there is any change with my battery
http://forum.xda-developers.com/showthread.php?t=653598
After resetting battery stats in recovery, I still lost about 10% overnight while on airplane mode.
For my next trick, I'll use a task killer like "Process Manager"* to keep everything unnecessary switched off overnight. Maybe I'll be able to narrow it down to an application if it's not something integral to the actual ROM.
*Yes, I know it will use up the battery too
My battery drains ready and if I unplug it at 6am it won't last me past 4pm. I use my phone lightly mainly just texting. On the battery usage app it says 92 percent beside the display. I use the lowest setting for brightness. I currently have andromeda 1.0rom on my rogers captivate. Previously I had the cognition 3.04 but still the same problem. I've tried deletingbattery stats through recovery menu. I also tried calibrating the battery. Wifi is used instead of mobile network. Gps is off. Bkuetooth is off. Emails set to push (i read somewhere that push is more energy efficient than autosync)
Could this be a hardware issue? Any idea on what I should do about my problem?
How much actual usage does your phone get? 10 hours of battery life is abnormal unless you have like 4 hours of screen time.

Well you can check your screen time by going into the battery stats then pressing Display.
Other than that, it'll tell you how long you've used voice calls and stuff as well.

You can check your actual screen time by tapping the "Display" entry in the Battery Use screen. That will tell you how many minutes your screen has actually been turned on.
I have a similar problem: My screen seems to use a TON of battery power, and it's almost always over 93% or for battery draw. I don't see a huge difference in power use between minimum brightness and automatic.
I tend to use the internet and text/email heavily, but I'm wondering if even that could account for the insane battery use. Today, I unplugged my phone at around 6:40 am. By noon it was at 1%.
Before I started using custom ROMs, I could usually make it to 4 with what I considered heavy use. Now, I can't make it past lunch time. I've done the battery calibration, bump charging, deleted battery stats, and discharged the battery to shutdown before charging fully. The screen power draw has persisted through two ROMs and three kernels. I'm wondering if my usage pattern has just changed this much, because I can't find any hardware or firmware issue to account for this.

Yea our problem is pretty close, if not then identical. I'm using it moderately and its at 10% right now.unplugged it since 6am. Ive tried a lot of different methods to try to fix my issue to but still nothing.
A few minutes ago, I checked my battery use. Here's how it played out:
Unplugged for 58 minutes
Screen on time 28 minutes 3 seconds
84% battery left
92% of power used by the screen
Do these stats look normal for screen power draw? This is what I'd call heavy use (I've been reading forums), but should the battery be draining this fast?

I have no idea. thats what i want to find out. heres mine...
66%battery
9h27m52s since uplugged
display - 76% --- time on: 1h23m22s
wifi - 13% --- time on: 9h26m51s
cell standby - 8% --- time on: 9h27m42s
phone idle - 4$ --- time on: 8h4m29s
any idea? i slept at 3am and woke up at 930, but didnt charge the phone.
Before i slept the phone was around 72%, and when i woke up it was around 70%. from the time i unplugged it to the time i slept it went down from 100 to ~72% under moderate use.
are these numbers right to you?? the only thing i am worried about is my display consumption that seems to be killing the most. Also, wifi uses less battery than 3g/edge right? so i shouldnt have a problem leaving that on. even when im not using it.

That seems like regular battery life there. If your phone is reading your battery accurately, that means you would be getting almost 30 hours with pretty decent usage before it dies.

Here is another update. tell me what you think.
29% left
13h13m49s since unplugged
85% on display -- 2h 52m 44s
7% on wifi -- 10h 7m 44s
6% on cell standby -- 13h 13m 40s
3% on phone idle -- 10h 21m 4s
It doesn't even show me my voice calls and 3g usage. weird.
also, do you know if the timestamp on you batterystats.bin is supposed to change? is that normal? or does it mean my batterystats is wiping on its own?

I believe the timestamp is supposed to change with batterystats.bin being updated. The only way it is wiped is if the file is deleted completely.
And still, that seems about right to me. 3 hours of display is a fair bit. In a regular day I normally see about 30 minutes of display usage.

wow really? 30 minutes of display is like bascially not touching the phone at all.
Is there a reason why the battery usage does not show my voice call usages and my data uses (mobile data, not wifi)
I feel like my battery life is... Less than ideal.
I'm going to be doing a few tests, unfortunately, it seems like my battery dwindles very quickly in 30% chunks, according to JuicePlotter.
One thing I've noticed that helps a lot is disabling your data network in general, unless you plan on using it.. You can still send/receive texts and phone calls, and that's primarily what my phone is for. It helps save a significant amount of battery.

Unfortunately, because I am waiting for some emails i cannot turn off my data network. my data network is on when i cannot get a wifi signal. I also feel that this battery is not ideal. I cannot last for more than 10hrs unplugged time if i unplug it when i wake up. if I unplugged it before i slept it would be a different story for obvious reasons
again, any help is and will be greatly appreciated
Here's more stats (running Cog 3.04, Gen X 1.14 theme, stock kernel)
Unplugged for 16h 22m 40s
69% battery life
38% display: 41m 24s
23% voice calls: 29m 39s
21% wi-fi: 16h 22m 40s
13% cell standby: 16h 22m 40s
7% phone idle: 15 h 41m 16s
It seems like I can easily get around 40 hours of battery life here, but obviously I'm in the light usage market, although I do use my phone to make a lot of calls.
In the past, I found that running different modems and kernels (specifically DG's Firebird 2 kernel) drained my battery life faster. While I loved the extra power and features (Voodoo sound specifically) the drain on my battery life was not so hot (see above specs but my battery percentage would be closer to 30% than 70%). I recommend returning back to stock via ODIN, see what your battery life looks like, then adding a custom ROM, seeing what your battery looks like, then kernels, then modem. That way you'll find the source of your problem. If your battery still drains heavily on stock, try a different (possibly new) battery. If its still doing the drain, it's gotta be hardware related and you might need a new phone.

Interesting, I was at 18% battery after 2 hours 45 minutes of screen time. 93% screen, 3% wifi, 2% cell standby. I'm starting to think that a) the screen really does just use a lot of power and b) my battery is becoming deficient.

I was actually thinking about returning my phone back to stock, unfortunately i do not know how to do it. I came across the odin3 one click downloader, but i was told by some to not use it since it is for AT&T. I am from canada and I use Rogers. Any ideas?
ok....am totally depressed with the awful battery loss that i am left speechless!!!...
here's what i did
3 and a half hours on standby....45 minutes of music playback on headphone in LOW volume.
1/2 hour of angry birds @ full brightness.
15 minutes of surfing @3g with full brightness.
rest the phone was idle.
tried battery calibration, wiped battery stats, using task manager regularly. nothing helps.
v20? mine draining batt as well..
Im on temasek P20-32 and using Wi-Fi more than usually and battery is droping down every minute. Ill try kernel nova 11c and hope that this is my last chance.

cyanogen sucks for battery, it will drain like hell with wifi on
Mine also drain battert very fast! even in my sleep time. but the strange thing is even battery reached to zero, it doesn't turn off! i think it has a problem with battery level indicator.
Ps. now i'm using V20N kdz. considering about turning back to V10E Thai but regreting the smoothness of gingerbread
same here with V20N when i sleep i put`it in plain mode with 90% when i wake up the battery was 0% and now i`m back to V10F in battery monitor say`s at a certain hour/min the battery from 70% was gone to 0% and about activities that drain nothing strange , seems normal like battery monitor say`s
I have some tips for the battery:
- use your phone till it drops to 1%
- reboot you phone
- charge it till 100% (don't use your phone while it's charging)
- then turn it off
Believe me,it'll last for a week

Maybe you just have ****ty ( malfunctioned) batteries ? Buy new ones and test.
I am NOT sarcastic.
OP where are you? I am using CM7 #39 stock kernel, with no simcard, dropped 6% in 8.5 hours idle. But if there's data connection available and sync turned on, you only need 10-15 minutes to drop 6% (idle).
We need a good kernel, redy2006 told me if anyone could port Nova v3 kernel into stock GB/CM7 all in one it would be great.
Like universal Siyah kernel i am using right now on my SGS2 (MiUI ICS), very great sleep setup and reasonable wakeup battery use. I can managed up to a day much better than my OB (CM7#39-stock) that can only managed up to 10 hours with the same apps and behaviour.

now i hv 94% left!!!
Does anybody experience a 3% to 5% battery drain just a few minutes after charging the battery to 100%? It has already reached 100% so I already unplugged it from the charger, but then I noticed after a few minutes, it went down to 97% already, and then in 10 minutes, it's already down to 96%. In 3 hours, it's down to 84%; in 7 hours, it's down to 38% and that's just on standby mode with Wifi/Bluetooth OFF, 3G OFF, GSM only. I've been experiencing this problem for the past few days now. I've already conditioned my battery, charging it to a full charge (100%) after draining the battery until it shuts the phone off. I only charge the battery while the phone is off and usually it takes about 3 to 4 hours maximum to charge it to 100%.
The longest time it reached was 12 hours (battery unplugged from charger) and that is with light use, such as Wifi is only on for a couple of hours, so basically just 2 hours web browsing and skype, 10-20 text messages and 30 minutes to 1 hour browsing the photo gallery or watching videos. No phone calls and 3G is off. The rest of the day, the phone is just on standby mode. I only have at most 10 widgets on the home screen. I have Avast Antivirus running in the background.
I am currently using Easy Battery Saver, Easy Task Killer, GO Task Manager and Battery Monitor Widget. I've uninstalled Juice Defender since I don't think it helps that much when it comes to the battery drain. Currently, the power saving option (available on Note) is enabled at 50%.

Any feedback or comment on this matter would be really much appreciated. Thanks!
From a personal standpoint. Your screenshots shows that your phone had never ever done a deep sleep at all. the 'Awake' mode is continously consistent as well. I guess the probable reason for that is you've installed ''Avast AV" on your phone. It's always running in the background (whenever the phone is ON). From my experiences, Any background application running would always cause wakelocks and the phone would never enter into deep sleep at all.
How bout you try uninstalling some of the background apps your using esp. Avast AV and give it a day to observe if your still having that battery drain issue. (Don't forget after uninstalling or removing those apps, try to wipe dalvik cache and battery stat and restart your phone after.)
and Oh by the way, I am using Juice Defender and contrary to your saying it doesn't help.. IT DOES HELP save battery as I my Note is able to reach 1.5- 2 days of normal use.
Cheers!
Yeah and download betterbatterystats and do some searching on it. With it you can discover what is causing those wakelocks. Search the web for more info on your wakelocks.

I'm using avast and never seen a drain like that. Only time I have is because of background processing. First thing I would do is turn off Background Data
Then as others have said - check batterystats to see where wakelocks are
Plus a rooted phone is a good thing. Titanium backup allowed me to freeze wi-fi sharing which also made a big difference
Finally - clear all caches from Applications menu and reboot

Only picture that shows that is the one with 1 minute 56 sec discharging time, so it was taken shortly after taking charger out. No suprise of it being almost 100% screen on time there if its only 2 minutes
Also installing "cpu spy" will give the cumulative time that your cpu spent at each frequency including deep sleep , mine is showing 88%
John.
Anti virus app is battery hog, I had avast before too, and I uninstalled it after 2 days using. Also that Juice defender, from my test before, it use up more battery than it saved. turning on and off those 3G/Wifi thing is using up alot of battery. and you know what? even the betterbatterystats use up alot, at least to me, becoz it scan what is up frequently.
Hello! Thank you all so much for your response. I've installed both BetterBatteryStats and CPU Spy and here are the results (please see attachments). Upon checking CPU Spy, it shows there that phone did went to deep sleep, maybe? I'm not quite sure, but it shows on the screenshot that it went to deep sleep for 19%. So does that mean the phone really went to sleep?? I'm sorry to ask this question, since I've never really encountered this problem before with my previous Samsung Wave phone, how will you know that your phone went straight to deep sleep mode?
Also, after 46 minutes or so, the battery went down to 96% already after charging it. The battery drain was already 4% in less than an hour.
@letters_to_cleo: I have not uninstalled Avast yet, since I'm still hesitant to use my phone without an AV. But I will try your suggestion for 1 day and see if there's any battery improvement.
I'm looking forward to your response or suggestions. Thanks again!
i am having problem too with new battery original samsung ( made in japan, finished in korea) previously i use samsung battery made in china, finished in korea. charged it over night with power off. it only last 13hrs. my wife phone can last 30hrs.
i've used batterymix to check the battery usage graph, the usage graph drop very fast compare to my wife phone. i'll post some screen capture of the graphs.
another issue is i used once wifi sharing. after turning switching the wifi sharing off, the wifi sharing service always at the background even after many reboot. how to turn that off??
You might need a new battery. Any rechargeable battery has a finite charging cycle. Just a suggestion.
Hi, all! I just noticed that the battery drains still even during deep sleep mode. After 3 hours or so (during sleep mode according to CPU Spy), the battery went down to 92%. It drains even faster when the phone is in use, especially when Wifi and Bluetooth are on, maybe 2-5% drain in 1 hour.
Maybe there's something wrong with the battery?? It's still a new battery and I can see some improvement each day though, but that's because I use it less each day. Before the battery can only last for 8-10 hours, then it increased to 12 hours, and then to 16-17 hours. BetterBatteryStats' current estimate to empty is 24 hours as of today, but that's because I only used the phone today for only a couple of hours, with 20 minutes Wifi and Bluetooth ON and most of the time, it's on deep sleep mode according to CPU Spy.
What do I do with the results from the Partial Wakelocks? Do I have to disable those apps?? The Kernel Wakelocks didn't show any reference apps running. The screenshots for the Partial and Kernel Wakelocks that were taken a few hours earlier still show the same results after 3 hours.

That would be really bad luck. I got my Note via preorder in Germany at the first day it was sold and since then I charged it everyday, sometimes even twice and there is no difference to the first day. If I get told by Samsung after 6month of normal usage the battery is dead that would be the last Samsung device I bought and I use a lot of Samsung stuff.
@ebichan24
Your last screenshots show between 9:35 and 13:35 5% of battery drain. That's not really a good value but ways lower than before. Did you delete some Apps or what did you change?
And since when occurred this issue? Did you install new Apps before this happened?
On my Note I had this issue sometimes without any changes but it was gone after a reboot.

Agreed with Kanalcommander.... try a reboot in the first instance.
Others have also noted that it takes a few refresh cycles before the phone more accurately reports battery use. Perhaps what you are reporting is because the phone and battery are new (new ROM or Kernel loaded?)
What I have done in the past is to reboot into CWM recovery then clear the battery stats (in the Advanced menu option) Recharge the battery to 100% until it says to remove charger and then use normally until battery down to around 20%, then recharge the battery to 100% again. Do this over a few days and that may help.
thanks, it is new battery two days old.

I was having similar problems with my new note and finishing full charge in 12 hrs but fixed some things and my last charge gave me 2d6hr seriously..few things i did were stop using live wallpapers! Get badass battery to thoroughly monitor stats and then use zdbox to extend life even much eg. I put phone to auto flymode using that app when its sleeping time rest i am more than satisfied even if on GB LC1 fw..waiting for official premium suite for ics since i recently upgraded from sgs2 using ics i miss that smoothness and much better bat life.. Let me know if can be helpful.. Good luck

That's what I'm currently doing right now, well, actually, what I do is I discharge the battery until it reaches 0% and turns the phone off. And then I charge the phone for 3 hours while it's switched off, I turn it back on again to check if the battery is fully charged and then I unplug it from the charger.
@Kanalcommander
**Did you delete some Apps or what did you change?
I haven't deleted any apps yet since I don't know which app/s to delete. Most of the apps I downloaded in Note were the same apps that I used in my iPhone4 and Samsung phone before.
**And since when occurred this issue?
This issue occurred since the first day I bought the phone, which was a couple of weeks ago. How long does it take to condition a new battery and new phone?? I'm sorry if I have to ask this question, it's just because I never really experienced this problem with my previous smartphones.
**Did you install new Apps before this happened? On my Note I had this issue sometimes without any changes but it was gone after a reboot.
I only installed recently CPU Spy and BetterBatteryStats and that's it. The drain of 5% from 9:35 to 13:35, the phone's just on deep sleep mode. And then from 13:35 to 23:44, it went from 92% to 74% while the phone is on deep sleep mode at 90% according to CPU Spy. That's 18% battery drain. It's just an unacceptable number for me. I tried rebooting the phone already, but every time I do so, just a few minutes after I turned the phone ON, there's already a 1% drain in the battery.
Also, does the battery really drain faster when the Wifi is ON? I've read in other threads that there might be some problem with the recent OS update that Samsung needs to address. Is this true?? Because as you can see on the screenshot below, the battery was still at 74% by 23:44 and then after I turned ON the Wifi and used it until 01:26, the battery went down to 54%. That's already a 20% battery drain in just less than 2 hours. I was only browsing through the Android Store and Skype.
Calibrate your battery in case you flashed any roms and for first usage I got my battery to 0% 3 times then everything is running great for example its at 47% now its 22 now and I have had it off charge since 7 morning..... i have wifi gps and 3g always on and use music player bluetooth and made some calls

My battery (also only a week old) drains quickly too. Can anyone tell me if widgets draw a lot of current? And then is it only the ones on the visible screen or do all widgets draw juice all the time?
I will ask such thing, did you guys check the battery expiration day ? Mostly sibce you got your phone almost a yeae after it was announced you nay get a bad battery, as for widgets the ones that are always active and asking for informatiom. Like location or weather over the internet yes they do eat your battery kinda fast.

Recurring battery drain? - Caused by memory of using app to drain battery?
Hello!
I used a battery drain app when charge left was 30% to accelerate drain to "die out" stage. After I completed the calibration process for unrooted phone as suggested in various sites (charge fully, switch off and charge etc.) I started using it from a 100% stage.
This afternoon when the battery showed 30% I saw in BMW the current flow was in -10ma to -15ma and it started spiking to hundreds. There was no change in settings or usage. From the 30% level it dropped to 10% in an hour and I had to charge again.
Was puzzled why the battery which was dropping around 0.5%/hour in standby earlier to the 30% level suddenly went down hill. My first guess was it was possible some file in the system remembered the previous usage history and replayed it out.
Any suggestions? Anyone faced this before? Everyone says LiOn batteries dont have memory so if anything it has to be the phone.
Thanks!
Hi
I think I might have an issue with the battery on an xperia sp which I got a few days ago. When idle with stamina on it's loosing between 1-2% per hour. I've used Gsam and recorded some stats to show what's using up the battery when the phone is not in use. Hope it makes some sense
loosing ~2% per hour phone in idle screen off
Stamina on, GSM only
Tried airplane, not much difference
Tried Stamina off, no difference
Charged to 95%
61% @ 10:16PM
34% battery use - of that
screen 56.3% (1hr 47min)
phone radio 6.5%
wifi 3.7%
apps 33.3%
TOTAL DRAIN ON BATTERY
-------------------
19% screen (avg 0.18% per minute)
2% phone radio
1.2% wifi
11% apps
____________________________________________
13 HOURS IDLE LATER - 17-20% BATTERY GONE
____________________________________________
44% @ 11.04AM(QUICKLY DROPPED TO 41% in around 2
minutes)
51% battery use - of that
screen 49.8% (1hr 48min)
radio 13.1%
wifi 7.4%
apps 29.6%
TOTAL DRAIN ON BATTERY
-------------------
screen 25.4% (WHY THE INCREASE of 6.4% when OFF all the time?)
radio 6.6% (+4.6%)
wifi 3.78% (+2.58%)
apps 14.8% (+3.4%, not sure why, stamina turns off all apps?)
6.4 + 4.6 + 2.6 + 3.4 = 17%
Why are these using up so much power in idle with stamina mode on?
Hello,
remove your simcard, reboot, got in to flightmode and let Wifi enabled.
now let phone unused for 8hours. its all Ok then accu should drain only 0,05%/h.
This is my XSP which i use only as alarmclock an every day 1 hour as Musicplayer.
I have tried without the sim card but it didn't do anything.
I notice in your screenshot though that there is no connection to 'mobilfunknetzsignal' ... mine is there even when the sim card is out, how did you get rid of it?

You must enable the flightmode under "settings->network->more" .
and then please install BetterBatteryStats to see if you have wakelocks and your device go in to deepsleep after turn of the screen.

Ah yes.. I tried flight mode one night and it still lost 15%
I have also used wakelock detector and it says phone is in deep sleep 99 percent of the time but still the battery is draining 1-2% per hour
Right now the battery is 27% down from 44% 2 hours ago... and I have hardly used it. I'll recharge and try again without turning screen on at all and see whats using it up.
Is there any explanation why the screen used 6.4% of the battery overnight when it was off all the time?
I'm too having about same problem..and am really interested in answer/solution,,,
Please, anyone?
I think I have fixed it but not sure. Phone was charged 24 hours ago to 99%, now its 94%. Definitely not using alot of power with stamina mode now but the screen was only used for 5-10 minutes, I've yet to test if it acts the same after screen has been used for a long time before going idle.
What I did was run phone setup again and update all apps
Now 88% after 40 hours, screen on for 25 minutes. Xperias battery monitor and gsam show completely different usage, android system takes up the majority in the xperia one but only 10% in gsam (under apps)
I checked wakelock detector and something called 'syncloopwakelock' was on for 4 and half hours. Is there any way to disable this? I already have auto sync in settings turned off.
A phone is meant to be used. Using it only from time to time to have as much standby time as possible is just a waste of a good phone.
I can get two days with heavy use. A lot of music, whatsapp, facebook and XDA Premium app..

I know, but there was a clear issue before as the battery was draining 20 percent overnight reducing the time I can actually use it. I was getting 5 hours screen on time one day, and only 2 hours the next. Just trying to make sure it has stopped, seems like it has
Would like to solve this syncloop thing though. I have no interest in syncing any accounts as I don't use them.
Simple fix
Change your rom, stock rom eats so much battery and has so many bloats, apps keep running in the background all sony apps.
MIUI is on jellybean and it gives me average of 1 day 20hours on normal use with wifi always on and sim card inserted..texting call and stuff
Problem has returned, woke up today to find battery under 50% and it was at least 75% when I went to sleep. Wakelock detector doesn't show anything and says phone was asleep all the time. Sony's battery graph though shows the phone was awake most of the time, but I can't find the cause in GSam or wakelock detector.
i think i have a idea. it can come from WiFi. there is a bug in all android 4.1. Set Wifi to allways on and deactivate/delete LocationBasedWiFi app from sony.
you can found it with BetterBatteryStats under Process.
Some screenshots
in this screenshoots the problem is not shown. When it comes from WiFi driver it is not a app that drain the accu, but a process.
The Line with awake in history details you can ignore, its buggy in 4.1.
I have searched through everything in Wakelock Detector and only process I found with alot of time is syncloopwakelock which is 4.5 hours. But this was already about 4 hours when battery was 85%
If I buy BetterBatteryStats will this show the problem? As you an see it drained at slow rate for 2 days then suddenly started dropping faster yesterday. I made no changes to Wifi settings, it is always on ... and I use Stamina mode.
Yes BBS will show the problem as "wifistatemachine", if the error should really be come from. you must not buy it, search on XDA for apk.
but if it come from your syncloopwakelock then i can not help.
Holy crap
I charged the phone to 96%, used it for 30 min (down to 92 percent) then went to sleep. Woke up and it was 28% and kept dropping !!! I've checked BBS, Gsam and I can't find the cause... again. After uploading these SS its at 12 percent.
