Screen Battery Usage When Off?

I am trying my best to figure out how I can squeeze extra battery out of the phone. I used to get 3-4 hours of 'screen on' time out of my Galaxy Nexus and now I usually less than 2h with best battery still being less than 3h and that's only when I am around wifi almost all day.
Anyway, in my attempts to identify the drain I obviously saw a lot of the same things other people did: constant wake locks and I know there are threads for that.
However, I have noticed something I do not know the answer to: GSAM reports that my battery uses roughly the same % of battery when the screen is off as when it is on. What the heck? I don't get how my screen uses ANY battery when it is off. Does anyone know why this is reported like this?

I've tried using it but it does not seem to work well for me. I set a custom ref. when I woke up and the battery was at 100% and it seemed to work for a bit but when I checked it 3 hours later after travelling to campus and attending class and it showed no data at all regardless of when I selected it to show me data from (since unplugged, since charged, since custom ref.) Does it not work with stock kernel?
In the mean time, GSAM is providing some good information at least for an initial diagnosis.
Are you implying that it is not correct in telling me that of the 31% of battery used by the screen 17% is discharged while off and 14% while on? It says: Discharge while on/off: 14% / 17%

Device must be rooted so BBS can work. Try going in advance and check alarms (root needed) SUPERSU will popup and ask for permission. Don't forget to refresh time to time whenever you open it to get latest numbers.

I am rooted

Nexus 4 Stock Android 4.3 Screen battery drain

Hello everybody, i bought my Nexus 4 2 days ago. Well, it comes with android 4.2.2, then i updated to android 4.3
But i have a problem, the screen leaves 43%-50% of the battery.
The minimum is 43% of screen battery usage. And the bright is at the middle, its not the maximum.
Can someone help me? If i use 3g/wifi or play a game the battery finish in just 12 hours...
Just wifi + standby sometimes 15 hours..
Thanks to all.

That's fairly normal. Screen will be the highest unless you make a lot of voice calls or listen to a lot of music.

No, its not normal.. I was charging my phone and now i removed the charger (full charged) and the screen was with 81% battery usage but after 2 minutes it down to 51%-55% at the time im writing this answer its 55%
In 10 minutes just with wifi on is 96% now.
Thats so bad.

My advice
Rooted Stock.

hmm its 62%, well, i think its not normal, well lets wait google make a new update..
Now i restarted my phone and the screen battery usage is 7% lol.. this is crazy.

Just disable the: Settings > Location Access > Wi-Fi & Mobile Network Location.

Disabled now. Lets see how it will work.

Remember that disabling that setting means you practically have zero location services working. you're relying on GPS only, so apps like Google Now, weather widgets, etc. will not work.
The analogy I like to use is to solve a leaking pipe issue by shutting off the water main. Sure the leak is stopped, but you're not going to be able to shower or wash your hands. So in the end your water bill is $0 not because you stopped the leak, but because you also stopped doing other things.
I don't doubt you'll stop the battery drain, but we never really fixed the leak. I guess only Google can do that.
Edit: What I also noticed is that if you've already booted up and you disable the location services via Mobile Data/Wifi, then you end up getting 100% wakelocks. I can upload the screenshots after I get off work, but I tried several times resetting CPU Spy and BBS stats and it was 100% wake.
Once again in the water main example, if you turn off the water main while you shower, the water left in your pipes will continue to flow. It's not the same as turning off your shower which cuts off that water to you immediately. What probably happens is you're revoking location services permissions by unchecking the box, but apps like Google Now, Weather Widgets, etc. will continue trying to request for location. Since you've given the apps permission to use location services, it will try, but since there are no location services GPS, it will just continue to wakelock.
A reboot does solve it where I think the app will stop requesting for location services.

I think The main problem is not the location settings
I disabled it and my battery its like enabled.
It drain 5%-10% in 30 minutes or less with just WiFi on.
This is really bad..

I don't think you quite understand what it's displaying.
The battery history shows the percentage used of the battery consumed. So if your battery level states 75% and the screen states 60%, that means out of the power consumed your screen used 60% of it.
In a typical day the bigger percentage your screen uses the better. That means you aren't suffering from wake locks or other battery draining activities.

Yes, but i think the battery is going a little faster than normal.
If im mistaken sorry.

Solved nexus 4 android 4.3 battery drain
:good: You have to disable in Google Now > Settings > Voice > Hotword detection.
This feature turn on the mic all time and try recognize your voice to do a action.
Just disable that, and the battery will take a good life duration

I made this.
But im having yet the battery drain. I wake up and i take off the charge, it was 100% after 15 minutes with wifi and facebook, whatsapp on the battery drain 5% (95%)
After 7 hours (now) with much use (playing modern combat 4 15 minutes, real boxing 5 mins, dead trigger 5 mins) with 3g always on, the battery is now 41% (now i turned off 3g) is this normal??
Or my battery is really going faster than normal?
Edit: I started to play real boxing for 10 minutes again, the battery was 40% after playing 30%. Wifi and 3g off.

How exactly do you update it to 4.3? Mine's still on 4.2 and I check Software Update in the phone and theres no upate.

Well it was on the software update..

[Q] Battery drain issue

Hi,
I got my second android phone (LG G2 obviously) this christmas, and I haven't had time to properly use it (I don't have a micro SIM yet). I noticed that my battery is going empty pretty fast, although I heard this phone has a amazing battery. My friend got this phone too and he told he's been on one charge for about 36 hours with constant wi-fi connection, app downloading, playing games etc. so I figured something's off. I charged the device before going to bed and when I woke up (10 hrs later) battery was on 85% (only 2 MINUTES of screen time!!!!) and I had no apps running on the backround, no nothing. So now I'm thinking is there some easy fix for this or should I return it and get a replacement? Also something weird I noticed yesterday was that even though I don't have a SIM card yet, but 16% of the battery was used by the phone application. I did some screenshots of battery usage today and yesterday too if anyone's interested.

There are literally dozens of similar threads... suggest you start searching.

And I literally have gone through 90% of them so I decided to start a new thead. Do you (or someone) think that a factory reset could help? And the next question might sound stupid, but if I do a factory reset then does the warranty remain? Better safe than sorry I guess

I just played 4 minuts of hill climb racing and lost 3% of my battery, this is not normal. Does anyone even have a solution for this? All I see on other threads is questions and questions, but I don't see anyone saying "That worked and my battery life is normal now"

It's normal if screen is bright. Especially if carrier bloat is still there. Post screens, all you have, and what carrier. The phone could have been sick in a search state.

I don't think my phone is tied to any carrier, it was bought from just a regular electronics shop, but frankly I did a facory reset and didn't realize that all my screenshots will be gone too. Do you really think it's normal that 10 hrs of idling causes 15% battery loss? And it has the stock LG apps (safety care, life square, cell broadcast etc.). What do you mean by "The phone could have been sick in a search state."? My screen brightness is on 70%.

It's normal with bloat in it. They all have bloat stock. 70 is high and can eat at the battery pretty good. I mean it could have software glitched and was struck searching for activation behind the scenes. Use Wake Lock Detector and see what is keeping it awake.

This, almost 20% drop was caused by downloading 3 apps (facebook, facebook messenger and twitter), updating ~10 apps (all done via wi-fi) and rearranging my home screen.

Steamer86, are you sure? My friend told me that he has been 36 hrs on one charge without changing any settings and just downloading apps, playing games and testing the phone.

Your idle is great at that point in time. Facebook is a battery killer. That's a lot of activity with 70% brightness all the time. It's 17% and medium higher side usage and an hour+ of screen time. What are you expecting? At this rate with 70% constant screen and Wi-Fi pushing pretty good you would get almost 6 hours OST. That isn't bad bud.

I hope you are right, but for helping and giving advice I'm going to hit that 'thanks' button

This night i lost 18% of my battery and my phone was almost all the time on deep sleep.

But i did notice something weird, battery usage shows that Android OS is using up most of my battery and when I press on it and then hit the back button then the Android OS changes to something called surfaceflinger for a millisecond (check the screenshots)

Can you try putting your phone in airplane mode and then turn on Wi-Fi? If you aren't using a cell carrier than there's no need to keep that on.
See how this works in increasing battery life for you.

[Q] Horrible battery drain

I'm using CM 11 (4.4.2) and MKernel.
As the title says,I am experiencing massive battery drains for no apparent reason.I charge my tablet at night (because it doesn't only discharge instantly,but also takes forever to charge - even if i'm not using it),at 12,I unplug it at 5-6 in the morning,and when I get back home at 2-3 it has 40-60% battery left.Not to mention how fast it discharges when I use it during the day.(like 1-2% per minute when I am just browsing)This shows in android: http://m.imgur.com/ZxxQZFu and this in gsam: http://m.imgur.com/UecetMU,BEa31nR,azM4kqq,DS5Ts3e,Sz5PQYv (i know,custom kernel,but the stock one was draining almost the same percent).I've disabled some gms services with android tuner but I dont't see a major change.FYI: my location ,location history,sync are always off and thre brightness is almost always at 0% and I don't have any rouge app. Any ideas what could it be?
BTW: Does anybody know what (wrong) service I disabled because no google app is able to connect to the internet anymore.

Maybe,but I have no ideea which one could.I can give you a list with my apps if you want.

Those screen shots aren't the helpful ones. You need screens of held awake time, and times waking device from Gsam. The main Gsam screen is helpful too.
....and you need Gsam root companion installed to see those wake screens.

Standby Battery Life is awful! N910C

As the title says, standby battery is awful.
I have all the bloatware disabled, only things on push are gmail and facebook messenger.
Cell standby is also sitting at 20% battery usage, no matter what, 2nd on the list behind screen time. Note 3 had exactly the same issue where cell standby is concerned. None of my other phones have had this issue, including my S2 with buggy as hell CM11, OnePlus One, Moto G LTE, etc.
No matter what I do, even with everything disabled and on airplane mode, there's a constant 1% battery drain every hour.
In my Note 3's case, this only happened on stock samsung firmware. When I flashed CM11, the issue went away completely. Something like 0.3% drained per hour instead.
So to me the issue is with Samsung's crappy software. I know the battery life was woeful on the Note 4 anyway before an update came in to fix things up a bit. Maybe they're saving the fixes for 5.0?
I know a new update for the N910C was released a couple of days ago too, but not available on European models yet.
Anyone else having these issues?

I dont have this issue at all my friend if i were u id try a complete wipe 1st, some people have had this issue too so returning could be an answer

Same here...

I only lost 4% battery overnight and don't have this problem too

20% battery loss on standby but mobile data was enabled.

^ you may have a bad app and/or bad signal

I have 4 bars lte at home, 2-3 bars at work, wifi always full signal at both work and home, one is ac 5ghz, other n 2.4ghz, no difference in drain either way.
Ive done a factory wipe 3 times now, even through recovery once. No change. Better battery stats and gsam both report no rogue apps, and ive also tested by having no apps installed, with and without bloatware disabled.
Im not really keen on the idea of voiding my warranty to test other kernels etc, and the only other option is to flash the ank5 update to test.
Ive attached another screenshot showijg the issue better. The drain gets noticeably worse after the first 50% or so, but that could be caused by many things, like inaccurate readings.
Like i say though, 1 of my 2 note 3s had the same issue. Could well be a faulty wifi/cellular chip.

Ignore the time its been on, the same thing happens during a day of heavy usage when in standby, same level of drain constantly.
1%+ may not seem that much to a lot of people, but with my usage i should get through 2 days regardless. It should be less than half of what it is. From the curent reporting in the battery stats, im losing almost 50% of my battery in standby over a day and a half or so.

Is location / sync off? Those a major battery drain during standby.

The only things enabled for sync right now are the basic google apps such as chrome, calendar etc. They rarely sync though, and no other phone I've used in the last 2 years has had an issue with them.
Samsung sync constantly returns errors so I leave that off.
Last thing I'll be trying tonight is a full wipe without disabling any built in apps. Its doubtful, but maybe one of the core shamsung apps are trying to communicate with a disabled app or something. I really don't know.

Any update?
My n910c is terrible too. 15% battery loss in 3 hours of standby alone! Wtf! Tried every battery saving trick' no location on etc...

i would suggest u do few thing while u get on bed next time,
Full charge your phone and unplug before you on bed,
1. Restart the phone while on charging,after restart go to home screen and lock the screen and unplug then go to sleep,check it at the next morning u wake.
2.Left the phone with your daily apps running,full charge and unplug then go to sleep,check it at the next morning too when u wake.
this is how i solve those apps running not right.
like the screenshot below,
An apps running at night drained 30% battery within 6hours & 30mins & without switch on the screen or touch anything since i'm asleep *with wifi on*
2nd screen shot shown that cm browser running and consume 94% of processing among 30% battery
while cpu only running 20mins since i had weather & sync on during night.
After that i report to cm team and they send me latest version,
after re-install my phone just back to normal.
now my N910c note 4 is consuming 1% every 1.5hours standby with wifi/3g connected *my area 4g only 1~2 bar so i changed to 3G*
average daily usage were 4.5~5.5 hours screen on time with social apps,browsing infomation,checking e-mail every 1or2 hours,reading news with flipboard,news app,drawing something,watch some youtube video & with auto brightness but indoor most of the time.
hope this would help you

I did a full wipe, installed ANK5 update, unplugged at 10pm at 100%, woke up at 7am with 97%. This is what it should ALWAYS be.
However, after the 2nd charge after the full wipe, it's back to what it was, if not worse. Last night I unplugged at 11pm, woke up at 7am with 92% left. That's bang on 1% an hour again.
There is nothing keeping the device awake at all. It's very frustrating.
I can only assume Cell Standby is so high due to the fact that the phone isn't actually doing anything while the screen is off. After a 20hr day with only 1 hour SoT it's sitting at 72% battery left, with cell standby at 31%, just above Device Idle at 29%. It's a mystery to say the least.

Thanks for your post. I'll definitely try restarting etc again beforehand. I'm also considering another wipe, as S-Voice being disabled seems to cause quite a few errors in the camera app. The battery drain increased after I opened the camera app too, even after force closing etc. That could just be coincidence though.
1% every 1.5 hours still seems like a lot to me, but it seems like you have a lot more apps and things running, so it's actually very good!
Very tempted to just root the thing now and throw on a debloated OS and custom kernel.

Last night i go sleep with 10% of battery left, ( im not force closing any application at all - just exit ) when i wake up ( about 7 hours of sleeping ) phone was showing 8%
No data/wifi/gps etc. If you are not using mobile internet, switch to GSM! It takes more than 30% less battery power than 3G

I'm thinking this is a hardware fault of some sort. Maybe battery, I'm gonna replace and see cause tried from full charge placing it in airplane mode to see if signal was causing the problem, didn't touch it, screen off whole time for 2 hours. Upon looking at it I saw I'd lost 7% battery! Omg! In airplane mode?! In 2 hours?! In standby?!!
In normal use there are no Rouge apps or strange readings in battery stats at all. May be hardware fault.
I've had the N910K exynos, 6 hours plus sot battery life
I've had the N910F snapdragon, 6 hours plus sot battery life
This n910c give me 3 hours sot. I'm pissed lol. Right off!!

Thats really weird, it can be issue of the battery. My 910C has about 8/9 hours of SOT ( wifi only ).

Your mobile signal is very poor. I believe you have full bars but your screenshot ... well it shows us that your reception is poor. It may be one of the causes for your fast drain...

My SoT is fine if im only using it during 1 day. Its usually close to 6 hours. But its not heavy usage, just browsing mainly.
Let me know how the battery change goes. Im likely going to order a spare anyway for when im away from home, so will also report back.

At work its pretty poor, usually a bar or two on lte, but no other phone ive had has displayed battery drain like this in standby.
That still doesnt explain why it drains 1%/hr with nothing happening at home though with 4 bar lte and full wifi signal.
Ive also noticed voice calls are taking up significant battery. A 3min call used more battery than 20 mons of screen time at half brightness apparently, unless thats normal.
If its normal, then to me the cause seems to be battery related. If not, then faulty cellular chip.

Also heres some more screenshots.
This is over the course of the day with barely any usage.
The chunks where its awake, that's just when I'm playing music, not a rogue app.
Note the big standby drop at the start, then the standby drop later, both completely different amounts of drainage, yet both when doing nothing.
