Battery drain from a non-running app? - Nexus 5 Q&A, Help & Troubleshooting

Hi. Its been a few days since my Nexus 5 battery has been drained pretty fast. Lasts only about 4 hours after fully charged with little use. Since I recently started working in a really poor reception area I figured that was the problem, my phone constantly trying to find a signal, but when I go to the details, I see that Instagram is responsible for using up 40% and it wasnt even running!
Im no developer, or even experiencied android user, but, how is this possible?

Welcome to android and app permissions. It's accessing a number of things on your phone with location probably being the number one. Get something like xposed and app ops to tame what the app is allowed to access. You should also get gsam or BBS to get a closer look at what is using your batery.

This happened to me last night with a messaging app I used to replace hangouts. It dropped about 12% overnight with data and WiFi all off.
I looked in battery use and messaging sucked most if it up. I cleared data in the messaging app and that fixed it. Later today I switched back to hangouts until I download another messaging app. I don't trust that one now.

Thanks for your reply. I'm guessing I need root for Xposed and those other apps ? Like I said I'm just an ex iPhone user who just converted to Android. So haven't given myself the time to tweak around.

you dont need xposed. looks like instagram had a stuck process or was stuck syncing. a reboot usually fixes that. there are other ways to fix things, other than installing xposed(as xposed could bring in its own issues). there are many apps out there that help, greenify being one of them. also, there are a few great apps to help you stop wakelocks that are out of control.

[Q] [HELP] Draining battery

Hello,
I need some help with my evo...i have it running on the fresh 3.5 ROM and netarchy-toasts kernel, latest version and all. I am overclocking as well, but nothing to drastic. Until recently, the battery life on my phone went into the ***** literally. Before it went 24 hours plus with medium to heavy usage. Now i can leave the screen on and literally (no exaggeration) watch the battery drain sliver by sliver. I just did a complete data wipe and reflashed the rom and kernel both in hopes of resolving the issue, but its still draining. Any help would be greatly appreciated, I really need this fixed but cant figure it out on my own :/
edit: the only time this happens is when the screen is on, when the screen is off it STILL DOES drain more than usual, but nothing compared to what happens when its unlocked. My though is that an app is running in the background eating up my batter life, but i have no clue what it is or how to locate it.
This is what the battery usage is looking like. Always Android system up at the top

Disable your mobile connection when not using it turn auto brightness off off auto sync but the main factor is.the mobile connection turn that off when not using and u we get better battery results
What's gd for these kind of things is juice defender

I forgot to mention that i have juicedefender installed already, and set cpu with profiles as well. one of the profiles is for when the screen is off, set for 300/300 (not accurate, but is set around that)
If its going as fast as you say (literally draining in an hour or so) I would say check your batter, try a new one. Otherwise you already have juice defender (which I tried and it really didn't do much else) so everything should be covered. Try wiping Dalvik cache, also try wiping batter stats (both are in clockwork recovery under the "advanced" tab.
Good luck and sorry if this doesn't help
Hey,
Download Juice Defender and AutoKiller fro the market and watch the Magic. me and you have the same phone and same rom. Note: delete any tsk Managers ou have because they will interfere with juice defender..

mm-qcamera-daemon battery drain

Destroying my battery life. Never had this before but recently my battery has been utter crap because of this. Always have had the same setup with every ROM I've had with Franco kernel. But this is ridiculous; at this time by 1pm I'd usually have 85-90% but I'm already at 68%. Anyone else have this?

Looks like an issue with Yahoo! Messenger's voice/video plugin
Have you tried uninstalling it or configuring it?
Or do you have any other third party apps that use the camera?
It happened to me multiple times, this is caused by an app using the camera wich crash. For me it was Snapchat, it told me that it could not access the camera so I stopped the app but some hours after I saw that this "mm-qcamera-daemon" killed my battery. After a reboot everything was ok : Snapchat working correctly and no drain.
I think that if you get an app saying that the camera is not accessible, immediately reboot your phone.
it also shows up every time you take hdr photos
Seems like it's snapchat guys. It wasn't able to access camera. Reboot fixed it temporarily but this is annoying as I notice it happens a lot now. Thanks for the info.

Yes. I have this issue, since a few days, too.
There is maybe a bug or something. I found a thread where lot's of people reporting the same issue: http://code.google.com/p/android/issues/detail?id=60058
In another Thread here, I found some solution possibilities like uninstalling Google Goggles. But it didn't help me.
So if anyone founds a solution how to (manually) fix it, please report. Not using the Phone and have a battery drain of about 50% in ~5h is annoying.
Maybe someone can make an app that detects which app is causing this problem or which can kill the process!?
€dit:
I have neither snpachat nor Yahoo Messanger installed
Google just announced a fix for this bug. Android Central: Google pinpoints Nexus 5 camera/CPU usage bug, fix coming in next Android release. http://google.com/newsstand/s/CBIwzPD-ihI
If this post helped you, feel free to click "Thanks"... Thanks!

I've had my phone ever since 4.4, this only started happening recently. Instagram is always at the top of the list now. I used to get 4-6 SOT now I only get 1-2 hours. Anyone else having this annoying problem?
I sometimes get it, a restart fixes it. Though it can be annoying because you won't notice that it's doing it until you realize your battery is going down faster than normal.

Pretty sure it's been the last few updates since it happened on my n4 too before the n5 came out.

Do you use the camera inside Instagram? If so, then stop using it.
Try clearing cache/data of instagram and reinstall it after a reboot.

The problem is that when a camera app like the one that allows users to click pictures or Skype is used, it continues to run in the background and uses CPU cycles. This not only leads to the battery drain but the phone also heats up.
Instagram uses the camera.

It doesn't seem that the latest update to Instagram has helped things.

This isn't right surely my phone gets way too hot as well and I'm only browsing social media so far I'm really not impressed with this phone as my sms texts crash too and I can't delete conversation or it takes way too long to open a conversation.
In the first screenshot what is your screen time?

Probably not even an hour mate, it's ridiculous
Strange... Your phone came with Android 5.0.2 preinstalled? Now I see you're using 4g ... For example now I have 54% batterry with 2h 40 (music,web browsing on 3g+). I heard the Android 5 is a major battery drainer (especially if you re staying on 4g). Try to make a few full discharge/recharge cycles or try a hard reset.
For example I don't have a battery problem even that I'm running Android 5. But I've manually flashed it( from Android 4.4.4) . This is my usage for today:

Ahh I see well I'm running the 5.04 I think, I can't update the software so im presuming it is the latest one, and sync where would I find this? Sorry I'm new to androids. You see yours is on about 50% and you can still get 10hours+ mine is on 67% at the moment and it's saying it won't last another 4 hours. I think I'll let it run completely dead them put it on charge
Settings->Accouts-> and uncheck auto-sync data. And about battery predictions they are not so accurate,at least at the first 1-2 weeks... Trust me this is a great phone in matter of battery just give it time. With proper settings and medium usage(4 h 30m screen time) you can get something like this:
This is my usage data that I had 2 weeks ago . Medium usage,web browsing,fb and some pictures .

Ah I see, that's the dream right there lol. This is the second day im using it, it's lasted longer then it did yesterday but it's nowhere near yours lol. I really hope it adjusts it's self by the end of the week.
Also do you find you're phone becomes warm to hot just browsing the Web?!
Depends... On chrome after 20-30 min but I also listen music and it's not that hot . Also it's summer and the screen stays almost at maximum light and that heats it up too .

Battery life

So I came from the note 4 and thought I would see better battery and screen on time. I see the posts in the note 5 thread that people are getting 7-10 hours of screen on time and maybe the most I can get is 5. Is this from the sprint cell service or something else. I have a lot of apps disabled with package Disabler and I am not rooted. What are your battery stats?

Just about the same as yours. I get about 3 hours of screen on time. However, I do leave wifi, gps, and Bluetooth on all the time. I have a bluetooth headset connected for the majority of the time.
Most I get is about 3.5 SOT so I would say you're getting pretty good battery life.
Confused about the Office apps.
My battery life is good so I can't complain but I find that the pre-installed Microsoft Office apps are taking up quite a bit of my precious juice. Since I have not rooted yet I can't freeze these apps. Is anyone else consistently noticing these apps at the top of their battery usage?
You can use package Disabler to freeze apps.

I get great battery, just deboated and used an app called kernel toolkit.
I get 6-10 hours on screen if not more and all day battery with screen off, but my phone is seriously deboated and most apps stopped from starting.
I get over 3 hours in a 16 hour day. It's not great, but more than enough to get me through the day. The fast charge also helps for the heavier use days.
