Sensor causing battery drain? - Samsung Galaxy Note 8 Questions and Answers

Hi all,
I know that there are hundreds of threads already about eeking out more from the battery.
I can just about get to the end of the day without charging most days, but not always so I'd appreciate your help.
Using gsam battery monitor shows that TMD4906 proximity sensor has had 294 wakelocks so far today (1h 58 mins cpu time) since I unplugged 4 hours ago.
Battery is down to 69% for just 1h 17mins of SOT today.
Happy to send Gsam screen shots if that helps, but it seems a huge amount of drain is from the above.
CHeers,
Andy

ah sorry, forgot to mention that I've done a factory reset and manually installed apps one by one.
Same problem

You could try with "force doze" app, has an option to deactivate sensors, there is a thread about it

I'm having the same issue. Try leaving your phone with the screen down over the table. It looks like the proximity sensor wakelock disappears according to GSam Battery Monitoring.

Where does it show this information on gsam? All I see under Android system within gsam is tmd4906 prox usage 5 hours since 1D 7HOURS.

Gsam reports tmd4909 prox using only seconds, never more than 14 or 16 of use, I find it strange, because I use gravity screen app which uses prox sensor all the time!

Think I figured it out. Last night I didn't close my wallet style case and the figure remained low.
Basically it seems to be the wallet style case covering the front of the phone causing increased proximity usage it would appear. Will run without wallet style case for a while to verify.
EDIT : THIS WASN'T IT.

AKMD at 37%

Phone has been idle for some hours. I was checking the battery usage and the AKMD was at whopping 37%..
Is this really normal? any sollutions to this?

I have the same issue now... After installing the new market. :S
That is the rotation sensor. As a test try disabling screen rotation. This will turn off the sensor and you should no longer see that item appear in battery stats.
For the actual fix, I have no idea why this would suddenly start misbehaving like that.

So, I kept installing older and older versions of the CyanogenMod nightlies... I know that 124-129 all cause this issue.
I decided to drop all the way back to 113 which I had previously installed without seeing the issue. Issue is gone now.

Android system sensor usage!!!!

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.

Change Shake to Wake Sensitivity?

My gear turns on every time I move my arm it seems. Is there a way to adjust the sensitivity of it?

You can sideload the shake app (available in the playstore) and use this instead of the Samsung shake to wake motion.
In this app you can adjust the sensitivity. You also have more configuration options.
However, there is significatn baterry drain which in my case is comparable to what i have with the original shake to wake motion.

In my case when i have the official shake to wake motion enabled i have a battery drained that is comparable to what the shake app costs.
What about you?

I get a whole lot less than 10% battery drain an hour using stock wake up gesture. What do you get?
I have stock wake up gesture 7 sec ON time, screen brightness 3, and at the end of the day (7 hours of sleep + 15-18 hours of activity) I have around 50% of battery.
If You have substantially less - check in full setting what is eating your juice....
Install the fOmey ROM... wipe etc.
Thanks guys keep the ideas coming. I am going to try the shake app and see how that goes.

Maybe smth is wrong with my watch. Cannot explain it otherwise.
If i have Samsung shake to wake, 7 sec ON time, screen at 2 i may make the whole day. That is 15 hours of (low) activity.
I have null 10.1 and have wiped.
Is there a way for me to discover what the battery hog is? Someone has proposed the wakelock app but i cannot get any useful info out of it.
Can somebody help me?
Thanx

I am using stock wake up (sorry earlier post may have been misleading). GO to full settngs and battery to see what is consuming most... are You using custom watch faces maybe? Try to minimize amount of bright pixels on the watch face - make background black, use thin fonts, do not use GAAPS if you do not need it, do not use teethering... that what I can suggest.
In my battery stats screen consumes up to 60%, screen ON time for the day can be like 1 hour, I end up the day with around 50% of battery

No custom watch face, black background of course, thin fonts of course. Tethering very rare and gaps the same.
This time i had 25 hours of operations (now at 10%) with samsung shake to wake always off and the shake app active for about 4 hours.
Here are my stats:
screen 34%
phone idle 23%
andorid os 17%
android system 8%
shake 3%
bluetooth share 3%
nova launcher 3%
google services 2%
media server 2%
I will post again the stats with the original shake to wake on and compare.

[Q] WTF is up with my battery life (Sprint m7)?

Hey guys:
Here's my latest problem. Have been using BadSeed's 4.4.3 ROM for my Sprint HTC One m7 for more than a month with no problems with battery life (in fact, my battery life was really great after switching over to the ROM with the custom kernel. However, I am now seeing terrible battery performance. With very little usage, the phone is dying within 8 hours. Here are some images for you to check out. Hoping I can get some advice on whether I have an actual battery issue or this is a software problem. I'm afraid it is an actual battery problem, but I also have noticed some pretty big drain on my battery in BatteryStatsPlus. I ran a battery test using HTC Function test a few days ago and it passed with flying colors while in airplane mode Dropped only 10 percent with the screen on for an hour, well above the 70 percent cut off. I just looked at my battery stats and notice the HTC Function Test is eating a lot of battery. The thing is, I haven't ran any function tests for at least 3 days. Why is that still showing up?
@clsA: Any idea?
Anywho. Two images are attached for your viewing pleasure!
OK. It looks like my phone isn't ever going into deep sleep mode.

No. Now the top two are showing up as Fused Location (59%) and Google Account Manager (33.3). Ive noticed lately the phone barely charges while screen is on. Under Wake Usage, it shows Google Account Manager as being responsible for 6hrs and 18 mins of wake usage.
In Wakelock Detector, Avast is showing x2804 as top CPU Wakelock item.
Uninstalled Avast and wakelock has stopped and entering deep sleep again. Will see if this resolves the issue.

yeah I'm not to keen on AV software
My understanding of AV software on Android is that it is only needed if you utilize custom roms. I installed AVG and it doesn't appear to be causing any issues.

Note 5 bad battery life gsam?

Hey guys , i am using this phone for the last one week and so far i am not impressed with its battery life.its almost similar to my xperia z1.
I lost over 24% battery in the past 2 hours just listening to music and surfing a bit.
Please have a look at my gsam screenshot and tell me if something is wrong.
Any help will be really appreciated.
Thank you.
Friend, take sshot from you apps usage and screen. Add sshot from stock battery manager too.
Thanks for your interest in my post.
I have attached the necessary screenshots.
I was having 3-3.5 hours of sot with my 2 years old xperia z1 and almost same with my note5 .
Not happy at all.
Today i left my phone at 41% went to lunch and returned after 90 mins and found battery left is 30% doing absolutely nothing.
Just taking the sshots and posting it here used 4% battery!!!!
Is something wrong?
11pm to 7pm off charge....looks fine to me!
I come off charge at 6am and it generally lasts to 8/9pm without a mid day charge.
Your screen is a big hog. Is brightness set too high constantly?
I don't play games but you clearly do - clash of clans....again another drain.
Big screen = big battery usage!
I've resorted to plugging mine in while I'm sat at my desk for a few mins here and there.
MM is poor though. The deep sleep / doze seems to work randomly.

Yeah i get your point
Brightness is about40% and i do play coc frequently
But my concern is suddenbattery drain. 11 % drain during lunch doing nothing and now 3% drain just opening xda and replying to your comment
Is that normal?
Also screen awake is almost 2 hours doesnt seem like doze is working
Check any apps you've recently installed....or start in safe mode and see if the problem continues.
Clear cache....
I've set up a greenify process - when I tap the home key on the home screen it puts it into deep sleep. I don't think MM doze works very reliably. Also my screen is at about 20%. Can easily whack it up when you go outside temporarily.

I have used 2 full days with just whatsapp and stock apps installed still the problem persists.
Please look at the sshot ,2 hr 14 min sot is absolutely ridiculous
Try the following:
- Uninstall Facebook
- Amplify
- Greenify
Has helped my Note-5 battery life greatly.

An App to control how often your wakelock & alarms fire off - https://play.google.com/store/apps/details?id=com.ryansteckler.nlpunbounce
Also, worthwhile alternative = Servicely (need to be rooted) - https://play.google.com/store/apps/details?id=com.franco.servicely
Try de-bloat script too by Battlehero.
Its funny how you and i used to own a z1 lol what a coincident. Anyways i think i commented about your battery life before. Regarding to the amplify im mot sure if op has root. I suggest you not to root if you want to exchange it saying its a defective battery.if not then go for it root it and see if it will change your battery stats. Pretty normal things to do is factory reset , boot in safe mode, maybe reflash firmware through odin and check any mysterious apps draining battery. Also maybe try greenify non root way for afressive doze. It shortens the time needed before going into doze mode. Im currently testing it right now.
