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.

At the time I turned off the wifi thats when I stopped using the phone. About 54% battery when I went to sleep and about 7hrs later 1% left.
Your device did not enter into a deep sleep due to some program still running actively in the background. You should use another battery usage tracker for better tracking on specific applications that are running in the background causing the drain.
I should have a bar on the awake portion right ?

Not sure what you meant. Background sync and many applications are classified under Android System so there is no way to tell who is the culprit.
My own usage stops at the part where Awake and screen of bars stop, if an app was keeping the phone awake, I should have a bar on the awake section and none on the screen.
Hi,
This issue is familiar with me. So in wifi settings you have a special option which can be bring up by pressing the menu key which is left from the home button and there is a menu special or something.. and there you can turn on to switch off the wifi when the screen is locked! and do NOT forget to SAVE your changes by menu button!!
Hope this will help u
This issue seems to be going on and off but now its back again.
4hrs since unplugged dropped to about 92%
Just to be fair, it does show that in 4 hours you have used your screen, so much so that it's the 2nd thing on the list. I'm still playing with my SGN but on my SGS2 my screen is always #1 or #2, depending if I use it a lot or a little that day. And Android OS is always #1 or #2 as well. I'd say in 4 hours, 92%, that equates to 2% an hour, which isn't bad, while still turning on your screen every once and a while. At that rate you'll go over 2 days (50 hours), which is pretty good as I recall.
I forgot to take a snap on the screen time, it only has less than 7mins of usage.
My Tablet lasts 2 days before its totally dead with ZERO USE!
Updated to 5.0.2 as i hoped this would fix it. No change
Lost 10% battery while in power saver mode in a few hours!
Lags all over the place when scrolling, the play store is horrible when scrolling apps.
Right now my S6 has better standby on 4G and more life in use than my tablet has with no use!
Any ideas?
Can't speak for Lollipop, since staying with 4.4.2 and disabled auto updates. I only lose 2% in ten hours and the best Android tablet I have owned- especially in regards to low sleep bleed.
clearly something is not right have you factory reset it? That would be the first thing to make sure no apps are doing anything weird.
I flashed a whole new OS... should i wipe it?
You need to install a wake-lock checker, it will show how much time your tablet is actually in deep sleep mode, which uses the least amount of power, mine shows 97% time in deep sleep.
Some application can keep you tablet from going to sleep, alarm clock and sync can also, and apps/software you downloaded.
Do you get still get major battery drain after a reset, dont install any software/apps and the charge to 100% and then leve it for a few hours and then check how much power you have lost.
John.
Over an 8 hour period (avg) with wifi on, my screen brightness set to 10-20 range (that is the brightness I prefer on my tab s), and with greenify I lose maybe 1-2% battery. You definitely have some program or service constantly running or waking up your tablet, and due to the interactive governor that samsung uses your tablet wakes up at 1.9GHz each time to be more responsive/save battery by handling what ever is needed as fast as possible so it can sleep again. Unfortunatly if some app keeps going "hey, hey, I am here, I need you tablet, hey, hey, ect........." that battery saving governor will murder your battery.
So i wiped and its still 48 hour batter!
Battery %bleed
Losing around 30% battery over night idle.
*wifi & sync on...

Do you need to have your wifi and sync on for business or something, if not turn them off, of use an app to to mange them like the free juice defender ect.
Just install it, make sure it is enabled and then make sure the icon is on your taskbar so it has not been killed, and them forget about it for a week and see how it goes.

for some reason on this tablet, wifi murders battery in standby. if you turn it off it lasts much better... but this tablet and this tablet only, leaving wifi on kills it horribly. but problem is, when you wake it for teh first time in hours and wifi activates, all of a sudden everything syncs and it's so damn laggy those first few minutes of use. it sucks. only this tablet. never had this issue with my nexus 7. that thing gave me 7 days stand-by time.

Try putting your tablet in airplane more overnight and see how much power it consumes. I lose 3% over 8 hours when I put it on airplane mode and disable wifi.
Im sorry but this is BS.
Its clearly faulty. its going to samsung. i demand a refund.
How much power wifi uses depends on the distance to the router and how much interference it has to try and break though to get a good connection which means using more power, that is why wifi uses more battery power on some peoples tablets than others do.
John.
disregard.. just realized my screen shots were messed up. I'll post my standby time tomorrow.
Here is a very simple stock no root mini guide to getting 1-5% loss over an 8-10 hour period while sleeping or at least while the tablet is asleep.
1. Install greenify even if you are not rooted and even if you do that have the donor package there are many many apps that do not like to sleep, greenify will fix that for you.
2. Unless you are a Doctor, CEO, or someone whose very life hangs on getting the latest cute cat post while you are asleep try to adjust your sync times from under an hour to as high as you can. (If you are turning off wifi then it might still matter if the app wakes up your device just to see it can't sync)
3. Samsung has given you a very nice QHD screen. It is high resolution, Amoled, and other nice rhings but while you sleep you can not see it so turn the brightness down before you touch the power button to 5-15. If you wake up in a dark room and need to use your tablet that level of brightness is far kinder to your eyes and even kinder to your battery.
Just doing this generally kept my battery usage down to only 2-4% per night, of course then I rooted my tablet and installed TW detox 3.0 and now it is closer to 1-2% per night. Try any or all of these and I hope it works out.

losing 48% per day... screen brightness wont help will it when screen is off all day
Screen brightness is for those times that an app wakes up the tablet and turns on the screen to tell you something (new email, facebook wall post, new cat video, ect....) and yes it helps.
If you are losing 48% a day then you have some app doing something that is keeping your tablet awake for a good portion of the day. Or you have a defective battery/tablet. I can surf the web for a good portion of the day and maybe lose 48%.

Are you rooted. It's sounds like you have some wakelocks? If rooted you should use greenify and a wakelock alarm to fix the problem.
i'm curious to see what apps and how many you have installed. Can you post screen shots of your app drawer?

what email apps and cat video watching apps are you using that turn the screen on? no app that I have EVER turns my screen on at all. the only app that does that is on my phone, and it's from textra, an sms app that isn't on my tablet.

i got my device updated to B133 it said it increases battery performance but it seems my battery is draining fast...anyone having the same problem??... can anybody give a better solution
I have a "similiar" problem - my devices starts rebooting or bootlooping (not sure whats exactly is happening) when reaching 100% Battery (I'm currently trying to finger out).
In my Screenshoot you can see, that the phone is totally offline about 1-2hours at night while charing.

i didnt observed something like that cz i never charge overnight... but the phone heats quicker in the day light and the battery drains faster than before
This is just my personal experience.
I own Huawei P10 UK variant with carrier bloat (Three) firmware version: VTR-L09GBRC555B150.
Since I got update I had really terrible battery life.
The phone didn't last me a day with on average 2.5-3h screen on time. To improve my battery I dived deeper in settings and here is what I find.
Turn off auto brightness in notification menu.
Go to settings>battery and click on" lock screen clean up" close apps that you want to stop using WiFi /data when device is locked - is amazing to see how many apps actually use data when screen is off.
In same section turn off "Remaining battery percentage"
Also go to settings>more>mobile network and turn off "mobile data always on"
In settings>wifi unmarked wifi+ option.
After these adjustments your phone should really improve in battery department.
Also if you receive any update from Huawei it's a good thing to do factory reset to stop apps from using extra resources from before update.
Here are some screen shots
My Gear S2 operates as normal as it should, however even at idle, the battery drains rapidly. Once the unit is completely dead, I then dock it and it will say 60% charge, which I know is wrong given that the unit will not power on undocked, meaning the battery had been completely depleted. Unit charges normally but I think a bug is preventing it from reaching actual 100% since it believes 0% to be 60%. Is there a way I can fix this without tearing apart the unit or replacing the battery?
same issue
I'm having the exact same issue, did a factory reset today updated all apps still same. I use a basic watch face, turn brightness to 2, everything off except Bluetooth and can get about a day of use . Is anyone else having this issue and has a solution?
Battery dead
So update on this issue, (on the Gear App on the phones most updated version) I went to the basic watch face in gray scale, then turned off all notifications, under gear connection, I unchecked sync wi-fi profiles, and under about gear I unchecked marketing information. I'm not sure which of those if any made the difference but at the end of day one 16 hours of use I was at 70%. So on the second day I tried a colorful watch face with animations, and 16 hours in I was at 63%. So one of those changes I made may have fixed my issue.
I did uninstall and reinstall the app on the phone, as well as reset the watch itself, neither seemed to work until I did the above changes. Hopefully that will help someone, or at least help to find out what is causing the massive battery drain.

With all that I have done with my gear, most I was able to get was about 10 hours. Though today it did to something odd. It died completely like it normally does, (it dies anywhere between 3-10% ish, and when it does die, its completely dead) so I placed it on the dock. Two minutes later I check and it reports 34%, "thats odd" I think to myself so I undock it and power it up thinking I would get no more than 5 minutes battery life on it since it couldnt possibly have that much charge in two minutes. I also expected it to report a low percentage but it didnt. I placed it back on my wrist and it continues to run about 10 minutes later down to 25% and still going! I find it odd. My current leakage issue I think remains and might be why the watch doesnt last as long. I might end up getting a new battery and see. My top battery user: watch faces at ~45%, even if the face hardly came on, and I am using one with a custom background that is mostly pure black.
Drain
That does sound pretty weird. I had a custom watch face installed "Mr Time" and started with a brand new install and I'm slowly adding things back in.
I would suggest a fresh install of the phone app, and the watch, using the classic face black and white. If you can get similar results to what I have then one by one start customizing it. I tried a lot of things to get it to work, over several days and that's what worked for me. I even uninstalled all of the watch faces I want using from the app"i felt that Mr time was still running in the background, even though it probably wasn't.
Good Luck
