After weeks of tryna figure our my battery drain on froyo I think I pinned it down. In spare parts under battery history/ sensor usage/ android system is running on my phone 100 percent of the time.I've already wiped and that doesn't help.any help?

Ya I have 17 hours of sensor usage in all time (I guess that's since I did a hard reset a few days ago).
Yea and the only solution I've found is factory reset but I can't find it in cm6 settings nor do I know if factory reset does anything to rooted users
Factory reset erases all user data. It's essentially wiping Data and Cache partitions.
Has anyone figured this out yet? My phone has been unplugged for 1 hour and has 24 minutes of sensor usage when I've used the phone for maximum 8 minutes.

I'd have to bet it's an app doing it... You'll have to figure it out probably.
Definitely it must be some app you have installed. Try nandroid and wipe if you have root and if it solves your problem then nandroid restore back and uninstall apps one by one until you figure it out.
I recommend you to start uninstalling apps which using sensor as first.

My guess would be that the sensor usage is part of the android system, therefore it uses the light sensor to read ambiant light for automatic backlighting for the phone, proximity sensor for the dialer, light sensor for the camera and orientation? sensor for the gallery perhaps???
I would guess that if you turned off the proximity sensor for the dialer, disabled automatic backlighting, etc you wouldn't see the same results. Just a guess tho.
That would be any app that uses the motion sensor. Like the new gesture search that can be triggered by flipping the phone back and forth. Or maybe a Tasker task you set up for some sort of motion gesture. Or a live wallpaper that reacts to 'gravity'.
I'd first look for any programs like those that could be running. They are misbehaving if it is constantly on, even when the screen is off. Or it could be by design 'to shake the screen on' for instance.
I have a similar sort of issue but instead of android being 100%, I have internet at 50% under battery info/sensor usage?
I charged my battery to full last night, set my alarm to wake up this morning, then put my desire into airplane mode.
I wake up this morning and my battery has gone down from full to 88%? How is this possible, and more unusual, how has the internet been the reason when I had my phone in airplane mode?

Same problem
I have a Desire (running CM-6.0.2) and am experiencing similar problems. Mine is actually much worse than reported here; in 8 hours of over-night table sitting, my phone drained the battery from 70% down to nearly 20%!!
I am careful to check which Apps are running, and meticulously shut things down. I always have my 3G data connection turned off, WiFi off, GPS off...
The Testing > Battery History > Sensor Usage frequently seems to be showing "Android System" with times that even exceed what is recorded as "Running"!!
The battery performance isn't always terrible like this, but I've noticed when BatteryGraph shows steep decline, that the Sensor Usage is really high.
I don't know how to try to diagnose this further, but we've got to figure something out.

Sorry for reviving this old thread, but I have the same problem. I charged my phone two days ago, didn't use it much before the first night. The battery in the first morning was about 95%.
I then barely used the phone yesterday and just used a default browser for 10-15 minutes before going to sleep. Don't recall the exact battery percentage, but during the second night the battery had drained a lot more than during the first night.
I have disabled auto-rotation and auto-brightness, gps and network connections and the phone was locked in it's pouch.
Under battery history (sensor usage, since last unplugged) I have:
Android system: 1d 14h 56m 48s
Internet: 11h 45m 35s
I didn't use the Internet for more than 15 minutes.
What could cause so high sensor usage?
Was a fix for this ever found?
I'm experiencing the same issue where "Android System" shows the "Sensor Usage" in Spare Parts as running 100% of the time.
Hey guys --
I did a search and while there is much discussion of deep sleep problems, there is no clear way I could easily find to identify the cause.
I have CM7.20, the MiRaGe latest build on my NC, with the settings listed in my thread (see the sig). Recently I noticed that it is not entering into deep sleep, indicated by losing ~20% battery while it is asleep overnight in about 8 hrs. Battery results tell me it's "WiFi" taking like 30% of the battery, which seems quite odd, since I had it set to turn off WiFi while the screen off unless connected to the charger.
Any clues on how to identify the problem with deep sleep?
As for usage, I am using my NC 99% of the time with the following apps:
Moon+ Reader (probably 70% of time)
YouVersion Bible app (most of the rest of the time)
Dolphin Browser HD (maybe 2% of the time)
Enhanced Email and MailDroid - very occasionally but they are checking mail on 15 min intervals when wifi is on.
I have a ton of other apps installed but I almost never use them except for these.
Any help on how to determine what is causing the NC to not go into deep sleep will be immensely helpful. I have a 2-week Euro business trip coming up next month and I would really like to solve this before then.
Thanks!
Better Battery Stats might help. Try turning off sync before bed and see if you still lose 20%. If so, it's definitely some app that's the culprit. Grab something that will tell you what program is using data and how much/how often and you should be able to isolate it pretty quick.

OK, but it should be turning off wifi, and therefore sync for ALL apps, when it is asleep. Can an app override this setting? That's my guess, is some app is doing this. How can I ID that?

Like envygreen said use that app to track wakelocks. Even if wifi is off, some app may be applying a wakelock to try to sync.

Alright, I'm on it
So last night I finished charging it and read for a couple of minutes, then put it to sleep to see how it went overnight.
My Wi-Fi sleep policy is set to turn off wifi when the display is off.
When I got up this morning I checked it and it had lost over 10% battery over night, and I checked BetterBatteryStats and I think it is going into deep sleep but maybe not shutting off wifi.
I have attached the screenshots from BetterBatteryStats, and I think I need help interpreting them and finding the cause.
ok, so here I am replying to my own thread... If I am reading this right it seems to be looking like my wifi is on the entire time, not only when the screen is on. Is this the right way to read this? In this case, it looks like "Wi-Fi sleep policy" being set to "When screen turns off" is not actually working... right?

It sure looks that way to me too. It says wifi on 8 hours. Did you try toggling the setting a few times? Also you are on Mirage and he may have done something in his tinkering that messed that setting up.

yeah I did toggle the setting on and off, and in fact before I had it set to "On during sleep if plugged" for a long time, recently changed it, thinking maybe this was the cause.
But it does appear that maybe this is what is killing the battery. There doesn't appear to be any network activity when the screen is off, just looks like the wifi radio is powered up.
Any advice?

Hmm. that seems like an extreme step, but maybe ... wonder how much of the snappiness I will lose.
EDIT: OK I switched to CM7.2 stable. Nice I didn't seem to lose any settings. Let's see how it goes. Thanks for the advice, I'll report back here if it still does the same thing.
Also uninstalled beautiful widgets... figured maybe that could be causing an issue.
Oh, and I probably had a SOD kernel patch applied... perhaps that was the problem too
guess I should change only one variable at a time for a good test, but in reality I just want to get it fixed and not really diagnose it.
I was having a similar problem...what I did was run the V6 supercharger script, granted i am running CM9 atm but it took care of any problems I had with battery life and wifi signal.
Question: does having WiFi on keep the phone from going into deep sleep at all?
I have found that my phone is not going into deep sleep. I checked what is holding wake locks, and the time with wake locks is way less than the time the phone has the screen off, so it appears it is not deep sleeping, even though there are not wake locks.
I have an extended battery, so I get good battery life, but always interested in improving it. But I also have this thought that if I have to turn everything off, and only synch when I turn the screen on, that is not ideal either.

Get CpuSpy free on play store. It will tell you exactly how much deep sleep you are getting.
Having wifi on all the time should not prevent deep sleep. Only when things use it does it come out of deep sleep.

I have CPUSpy Free, and that is how I know I am not getting deep sleep. My challenge now is to identify why.
OK, so it seems that CM7.20 stable definitely fixes things. I didn't flash the SOD fix, so maybe the SOD fix was preventing deep sleep before, or maybe something else in the kang build was preventing deep sleep with wifi on when the screen is on.
However the better battery stats still seems to say my wifi is never actually going off. I am not sure I am interpreting the results correctly. It looks like the wifi is on all the time even though it's set to turn off when the screen is off. But I can let the NC sit on my night stand overnight and lose only a couple of % where it was like 10+% before. I still think my problem was due to some app that updated and not the ROM because the problem started weeks after I last updated the ROM.
Hey I have just bought HTC One 2 days ago. Compared to my old Sensation XE battery life completly sucks. I usually use phone without battery saver, on auto brightness and with Wi-Fi/3g turned on only on demand. Today 8 hours after unplugging phone from the charger I only have 26%. Screen was turned on for 2 hours and 45 minutes only and Wi-Fi worked for 3 hours and 46 mins. I might also say that I did not charge my One before usage to 100% as HTC advised. Was that very crucial? Do you think that phone might be broken or I should just give him time to settle baterry better.
That's sounds like what I get. I turn off mobile data when using WiFi and vice versa. I always use power saver unless I'm 3D gaming. Which is only on the weekends.
I've had mine for 3 months now.
I've seen people get 7:00 screen time on stock unrooted.
I think my battery's broken too. I can barely reach 3 hours of screen time. With 2 hours I get like 11 maybe 12 hours of on time. Something's wrong with our phones...
Does anyone have any suggestions?

Your battery stats seem on par with me and the OP. Seems that only a select few phones get decent battery life.
My kernel (android os) has been in the 25-35% range,it has never been that high before.
battery life lousy
I get pretty horrible drain too. I charged it to nearly full around 7:30 last night. I took about 2 minutes of video, sent one text, and checked my email 3 times. After that I went to sleep and the phone sat idle. At 6:30 this morning, I'm down to 9%.

Wow, that's real bad.. When my phone is off during night maybe 7% is gone. Then again I'm rooted and use greenify aswell as battery doctor if that has any affect.
On screen time seems like my battery drains pretty fast too though. After 2 hours of music and surfing and watching videos I guess atleast 40% would be gone.
My battery life became horrible, too. My phones loses 4% per unused hour. No App seems to be responsible for that drain. Flightmode or powersaving mode ain't making a difference. I hope we'll find a solution for our drain.

@Racingmatt your power management services is on for quite a bit. do you have alarms.? i would bet that you either that maps location enabled or something of the sort. cause you also have NLPcollector on for around 40 minutes which is a bit much. also i would turn off GPS if your not actively using it.
@Rachorid how are you setting up your wifi? is it set to always be on? or set to turn off when screen off? you have alot of wifi wake. might be due to that. i know when i'm at home my wifi actively pings all devices connected which will force wake up my phone. yea its a bit annoying but i live with it. otherwise i just keep my phone plugged in.
if you both can get some SS of alarms i can give you a better idea. and when you SS the alarms make sure to click on the ones with the most wake lock so i can see the secondary screen that shows what the actual wakelock command is happening.

Here are the latest stats. As you can see many Google wakes.. removing Maps/Now/GMail/turning of Location (a few days ago) had no impact on my drain. The 2nd app on Partial Wakelocks was used actively.
I also disabled Wifi for about 2 hours.. no impact, too. Flightmode also had no impact (a few days ago).

The reason I didnt give you a alarm ss is because I didn't have any alarms when I went to the alarms section. I also had all locations services including GPS enabled but I just now disabled GPS but left network location enabled I'll give you a screenshot later so you can see the differences
I know exactly how you feel that's what happened to me,u was expecting so much from the battery and it turned out to be the worst..give ya some advice...3g drains the **** out of the battery ,so always jeep it off and turn it on only when you wanna use it...that way the battery will be acceptable...

I had awesome battery life a month ago with Wifi always on, auto. brightness and every app on hourly sync. (I have my phone since 7th of march) Sometimes I didn't lost a percent over night (8 hours) and I just don't know what it could be because I didn't install another app and no app seems to be responsible for that stanby drain. My on-screen battery life is still good. It also doesn't matter which ROM or kernel I'm using.
Here is my latest stats after 12 hours with 5 minutes of GPS use (turned off when not using)and network location on all the time with 3g/4g on all the time(turns off after a period of inactivity) . I can't give you a alarm stat because I'm not rooted.
Lithium-Ion batteries used in today's smartphones need atleast 10 cycles to show optimum power
so hold on until 2 weeks then you will get the full performance
i get 2 days of battery on my HTC One (since i dont have internet on my Simcard)
its 2G connection and auto Brightness and switched bloatwares off
i use Android Revolution HD 12.2

with normal use 3.6%/h is pretty reasonable. how much screen on time was that including?
Hi!
I just noticed that my phone does not go to deep sleep if I have wlan on. Though I do not have any long wakelocks according to BetterBatteryStats, just some minutes total while the device have been awake for much more.
Stock .534 unrooted, newly repaired with _only_ BetterBatteryStats and CPU Spy installed. No accounts added etc.
Wlan/Advanced: "Always on"
Location-based wlan: "on"
Low battery mode: "on"
STAMIN mode: "off"
Location based services "on" / "off" tested.
When I have wlan on CPU Spy reports as Deep sleep unused, and instead most of the time is spent in 300 MHz.
Any of you that can reproduce?
Have the same problem. Is that normal that it doesnt goes to deep sleep ?

No, it's absolutely not normal. Something is keeping the device awake, probably a bug.
I left the device over night,
wlan kernel wakelock for 7h, but no long-standing partial wakelocks. I don't get it, how can something keep wifi awake without actually issuing a wakelock?
Bah I have suddenly been afflicted with this issue since yesterday. Noticed battery drain from 100% to 33% with minimal use between this morning and lunchtime while at work. Currently it is charging off my laptop but only holding its own, not increasing. Only had it a week, very little installed on it.
Battery life was fine for the first week of ownership, today it lost 75% with little or no use in 5 hours, then it did not charge when connected by USB to laptop it merely held the same charge, before quickly discharging again when disconnected.
No deep sleep all day

Hi, can you please verify that you indeed do not have any wakelocks caused by any other third-party programs you have installed? Just to knwo that we are in fact experiencing the same issue. You could also try to disable wlan (and mobile data (I haven't tested to turn that on, as I do not yet have a data plan).
The application needed to test that is Better Battery Stats, available here on XDA (or on Play): http://forum.xda-developers.com/showthread.php?t=1179809

Today's issue on my phone was driven by several hours of a "bam_dmux wakelock."
edit: and no partial wakelocks so no idea of the driver.

Ok. So it might be the same issue then, though I don't really know what the "bam_dmux" wakelock is.
FYI Mine is back to normal today. Lost 3% in 3 hours of light use. Only thing I have changed is I deleted a Wifi network from my preferred list that the phone was having trouble connecting to, may or may not be related.

Yeah seems to be a common android problem, some apps have runaway processes, others prevent deep sleep and I have also seen kernels lock CPUs. Shame Google can't put some effort into fixing it.
It's not an Android or a Google problem, it's the fault of the developer of the App which is causing this...
Since 4.3 I lose 0 % over night and I can use the table 1 hour every day for reading magazines, e-mail and angry birds for at least 5 days! Just great

Google / Android should not let an app prevent deep sleep imo. Or runaway with resources. But yes you are right some responsibility has to be with the app developer for sloppy programming as well.

In some cases it could be useful or even wanted. Think of an emergency app with running bluetooth and GPS. You would not want Android to kill the app in the middle of your tour

You can wathc under "settings" -> "energy management" -> "energy table" which app it is and you can prevent it to wake the device up and to keep the device alive.
A few weeks ago I had a similar but stronger akku draining problem with the google apps but its gone (a pitty that I can´t say what it was: me doing this things in the energy management or google updating its app).
My google play-services still wake the device 869 times in 3 days.
New results. Very strange. No power consuming app seems to be running, but I still got -3%/hour.
Battery statistics shows that 80% most power is consumed by the screen. But it the tablet was in sleep all the time, so the screen was off...

Check in Settings on "Energieverbrauchstabelle" (something like "engery consumption table") from Asus, there you can see the power consumption of the apps without Display. If you click on a specific app you can disable it to keep awake or wake tablet from deep sleep...
If that not helps you you should reset everything and go back to stock. Then you can check without installed additional apps if your "bleeding" still is there. Then install one app after another and wait between every single one to check which is the "bad app"...
So, in fact it was a hardware issue. I took another unit and it works perfectly. For now...
Anyway, thanks for your help, guys
With tablet off (deep sleep) I get 1 % battery loss in 12 hrs.
Best I have ever seen on an android device.

Yep, now I've got the same thing. 1% instead of 30%
With my N4 and now N5, I use better battery stats to find the culprit of battery drain. But you have to be rooted

have you registered a asus account on the tablet?
i did and i got same issue was chewing through the battery like crazy.
go to settings and power consumption and it should say how many times it woke up the tablet or stopped it from sleeping
