Maps has absurdly high number of wake ups, help?

I'm relatively new to android but have a computer background. I'm rooted and have flashed about a dozen or so different ROMS but ended up back to stock for a few of the TW features. I've been keeping an eye on my battery lately and noticing a extremely high number of wake ups from my maps application. Last night specifically I went to bed at 11:30ish with 39% batt life remaining. I woke up and 7am and I have 19% remaining. Phone wasn't in use at all. I had 3 emails and a google+ message come through over night. Looking at GSam Battery monitor maps has very high usage for something i'm really not using at all. it used 15% of my battery coming in below the kernal at 15.4% and the android system at 28.5%. The phone was held awake for a total of 1h 11m in the last 14h by maps alone and had 1743 wake ups.
I have since gone in and turned off location services. I was not using latitude or anything. Not using GPS although I do leave it on. I have google now installed and really liked the fact it would give me driving info when it was my usual time to head to or from work. The alerts for traffic for calendar appointments was also awesome so i'd preferably like to keep those working if possible.
If anyone has any info that could help it would be greatly appreciated!
Here are some screenies to help just in case.

You could try freezing maps with titanium backup. Not sure what effects it will have on anything else though. Just a suggestion.

Well I use maps all the time. I just didn't happen to be using it in the last charge cycle. So far this morning I went into the maps settings and toggled locatoins settings- report from this device to off. I'm currently charging (off my laptop so it's slow) and once I'm at 100% I can run another cycle and see if it's made any difference. So far it looks like the number has stayed the same.

I've seem many posts about this. Its a known issue unfortunately. Like you've already done, make sure location reporting is off and that latitude is disabled.

Yeah i've seen some posts but Latitude was off and most of the other instructions for disabling more services were for different devices so the setting paths were different. Maybe this will actually work. I've noticed a bunch of wakes preventing periods of deep sleep as well. crossing my fingers I solved it myself.

small update, looks like turning off the location history does stop google now from working with the traffic updates. While I really like this service, i'm not sure it's worth the battery life it's taking to fuel it. Could be related to using a port of google now with ICS and not official jelly bean, at least that is what i'm hoping.

Well it looks like I got maps fixed but now the system is crushing my battery. I'll let the screenshots do the speaking. Really looking for someone with some expertise to help me out. I'm lost other than switching to a CM10 ROM.

Turn Off Location Settings
Try turning off your LATITUDE LOCATION SHARING. That seems to work for a lot of people that reported the same issue. Its under System Setttings > Accounts > Google > Maps & Latitude

That's been off. Fixed the maps but now system is going crazy. This just started yesterday. I'm planning on re flashing stock and starting over

Not only have I rebooted, I did a Titanium backup of my apps, factory reset, and only restored my apps. no system settings.
The only thing I can think of is that I installed a few packages to enhance the stock rom. I'm going to flash over a completely fresh version and go from there.

Oh wow, well good luck! I would recommend looking at CM10 tho. Been using it for a month or two now and haven't looked back.

I really liked CM10, a lot. I just miss some of the reasons I bought this phone. Swiping contacts to text/call, motion settings, video playback pip. If they could ever get those on CM10...

[Q/ GSM version] Battery Drain due to Media Server

Hi all!
Recently, I updated my Galaxy Nexus to 4.1.1.
I found that the battery drains. Battery level went down 1% per minute.
I did not meet this problem when I was using 4.0.4
How should I fix this problem?
Thanks a lot

Hmm.. same here. Battery Life was better on ICS, that I agree. But JB is really awesome! Anyway, about your problem, I suggest making sure you kill your apps more frequently (Going into MultiTasking and just sliding them all away). This seemed to help me.

I have been trying to figure this out for days. I've read countless threads with no luck. I've got no mhaic , videos or pictures on my phone and its still using a lot of battery. Willing to offer bounty for a proper fix

Just the worst advice ever. You don't need to manage your tasks. If you've got an app misbehaving that's causing drain, you need to uninstall it and use something that's coded properly.

Well that's true. Sorry if I said it wrong. But yes, some apps are coded horribly like Facebook and cause terrible battery drain. So, just uninstall it.

I don't own this device but my battery was draining so fast and I flashed ,, pimp my rom,, and battery lasts for about 2 days (earlier it was barely 1 day)
Press thanks if I helped you

I've shut my Bluetooth off And the drain seems to have stopped

Search the forums and download better battery stats - you can also purchase the paid version from the play store - Run that for a day or so and it will tell you what is eating your battery.
Also, some more information (screen captions, your 'average' use, ROM, Kernel, etc) could help this thread a bit as well.
If you have a rogue app that is causing drain, better battery stats will help you find it.

After I got a program which tests mp3 files and removed all which had errors the media scanning stopped going on forever and killing the battery. I don't know which program off hand but I bet there are several free pc apps to test mp3's online.

This does not kill apps. It merely removes them from the Recent Apps list. If you want to kill apps, you have to go to the Apps manager in settings and force stop. Or use apps that offer such functionality like Android System Info.
---
I also have this issue, but force stopping the medisscanner (or related apps) resolves it temporarily. I'll try the mp3 validation suggestion

Solving of Battery drain Issue
Please check on your device on app which using most of the battery. I used GSam Battery Monitor so that it will shown me the most usage of apps consuming the battery. Just tap on it, tap "manage" then tap on "Force stop".
This accually required on every charge, restart or playing / downloading a media files. Some people suggest clear data on media storage, however, it clear all your custom ringtone and others too. By doing Force stop, nothing will be affected....
Enjoy!!

Nougat HUGE battery drain

Hi guys
Im having a huge battery drain since I'm on Nougat, and it's because of the android system itself. Not because of an app or whatever. Indeed, in like 3 hours I lost almost 40% only using Spotify.
Here is a screenshot -> http://imgur.com/a/24874
I know there is a ton of posts like that but I believe that battery drain-related problems are user specific, so..
And I'm on full stock. No rom, not rooted
Anyway thank you!

give us more information to help you. Rom? Kernel?

I'm on full stock ! No rom, not rooted, everything's stock

Here's what happened on my 5X, I got mine new about 2 months ago, had 6.0.1 and battery life was great with amazing stand-by time. Soon after, I got the final update of 7.0 Nougat, everything was fine and battery life was slightly better than before. About 2 weeks later, my phone started draining battery when idle with nothing turned on. I tried recalibrating the battery, doing a hard reset and nothing worked, it was still draining battery when idle (I lose about 25-40% over night every time) So I tried fixing this drain issue myself and here's what I did: I rooted the phone, flashed back to 6.0.1 only to find out that that idle drain is still there (I wiped cache and everything) When that didn't work I tried Cyanogenmod 13, the drain is still there. So I read about different kernels, and I flashed back to stock 6.0.1 with ElementalX Kernel and that didn't change a thing. I am currently on 7.0 rooted with ElementalX Kernel and my device is still draining battery when idle. I have done pretty much all that I could to try and fix this but no luck. I tried contacting people on the Nexus forums and the only thing they said is, it might be a software problem. But can't know for sure. If anyone can please help or knows what else to do it would be greatly appreciated. I should also mention that my fingerprint sensor died shortly after 7.0 update and I have no idea why. Btw every time I flashed a new rom, it was completely stock with no 3rd apps installed and still draining when idle. (Side note: I live in Slovenia, there are no google stores in my country)
Also there is no damage to my device, no drops, no water exposure. Should I take it to service to have the battery replaced? What if the problem is still the same? I need some help here..

I'd bet you a large sum of money that it's one of the Google apps holding the phone awake. Get a wakelock detector and find the culprit. All of that Google Location **** that they build into their apps just seems to run away and start draining battery. That's why I've permanently ditched having the Google app or Google Now Launcher on my phone.

I'll admit that I've used those apps before without a single issue. But every once in a while, usually after an app update, Play Services or Location Services would suddenly go rogue and it was infuriating to track down the issue. So I avoid those apps all together now as a precaution.

Same here.

What version of Google Play Services are you running? I believe a recent version (in the range 9.6.xx if I recall) had a genuine bug causing wakelocks.
The latest version (9.8.77) seems OK for me and the phone sleeps as before.

How did you ditch the google app? I can't even disable it. As for the launcher, I use Nova prime.

When I clean flash a new ROM I use Pico GAPPS which doesn't come with the Google App or anything and I just never install it from the store.

I did a fresh install of latest release of CM13 with the pico Gapps package, the only things I installed my self are gmail, drive and chrome, I also disabled all background processes in the developer options, set the animation to 0 and turned off all types of syncing, even before I added those 3 apps I was still getting idle drain. I don't know what to do anymore. I'm thinking of selling my phone and getting something else, but I'd still like to have the battery replaced just to see if it'll fix the problem although I'm not really sure it's just the battery's fault since more people are having the same issue. One thing is for sure, I will never buy the cheapest google phone ever again, my friend's 6p is running better and has more battery life on 7.0 than on 6.0.1.
EDIT: On this latest release of cm13, I got an android system message saying: There's an internal problem with your device. Contact your manufacturer for details.

Yeah I'm running the latest version (9.8.77) and today, out of no where, I started getting smacked with a ton of wakelocks from none other than Google Play Services.

Which cache did you delete? Like you wiped cache in TWRP or did you clear the cache of an individual app?

What kind of drain we are talking about here? Few per cent per hour or more? I had an issue with my old Note 4 recently, somehow it got wet and it was never the same. Battery drains in 5-6 hours. Generally, after you restore the software, there shouldn't be any drain, if there is, very likely it is a hardware issue?

last few days, androidOS battery drain

last few days i have a ridiculous battery drain from androidos - this is new
no new programs installed
on 7.1.1 stock
anyone else have similar experience>?

Doesn't seem to matter what version you're on or what phone. If it has android Google will eventually target you for some data/battery drain. Mine went from 100% to 59% over night doing nothing - this is on a Nexus 6 runniong 6.0.1. I usually only drop 3%-10% at night, but every once in a while i get hit with the google tax.

There is a lot of news around about a bad update sent out by Facebook and Facebook Messenger that are causing battery drain issues. If you use these apps you may want to uninstall, restart and then reinstall to clear out the issue.

Facebook Messenger destroyed my battery yesterday. I opened the app twice and it caused 20%+ battery drain between charges. Guess that really shouldn't be a surprise given the developer...

To my knowledge, there's really no way to troubleshoot wakelocks without root and Wakelock Detector. I used it and was able to identify nlpcollectorwakelock as my biggest problem. Other smaller ones were identified as well. This was all because my device was awake 100% of the time and Google Play Services were eating majority of the battery. I don't know specifically about the drain on androidOS, but the first step I would take would be root + Wakelock Detector.

Battery Drain

Ever since I updated to 8.1.0 with December security patch, I've noticed my battery draining faster than normal. I was getting 4-5 hours of SOT with around 45-50% battery left. This was after being off the charger for 12-16 hours. Now I'm getting about half the SOT at similar numbers. Anyone have any ideas?

Excuse my stating the obvious, but you need to find what process or app is using the battery. You should be able to get a rough idea just using the new features under Settings>>Battery. It will identify which apps are using the most juice. Run the phone in Safe Mode to see if your battery life goes back to normal. It could also be a service like Google Play Service which sometimes wigs out and starts chewing battery. Are you rooted? If you need more detailed information there are battery drain apps available to help isolate the problem (BBS and GSam). These apps require root to give the best results.

Not rooted and currently locked. I've downloaded GSAM and have adb permissions and it simply says things like Chrome, RCS Phone and Play services. If you see from the photos below you can see what I'm talking about. Chrome currently isn't that bad, but yesterday and the past couple days it's been like 9% or more of the battery.

Two things: I've never seen phone or kernel use that much battery. On one page phone usage is 33 seconds, yet it used 9% ? I think RCS is running the background all the time. See if you can toggle it to not run in the background under Settings>>Apps>. High kernel I'm guessing is a kernel wakelock or multiple. You've probably loaded app(s) that are creating the problem, but you need to find out which one is causing the wakelocks. There is a wakelock detector "lite" app that doesn't need root but I don't know how well it works. I know the root version works well. Lastly, on the first screenshot with the battery, scroll to the bottom of the page and see which apps are listed there. I'd be willing to bet if you ran the phone in Safe Mode, your battery drain would disappear, meaning your user apps are causing it.

Well in safe mode my drain is gone so I'm not sure which app is doing it, but to directly answer your question about the RCS it is an overall app meaning it is related to several Google play services. I'll upload a photo of it. I have to reboot into normal mode.
Edit: I'm wrong about that it was the play services.. I'll have to start uninstalling the apps to determine which one is draining the battery I guess.

Well in safe mode my drain is gone so I'm not sure which app is doing it, but to directly answer your question about the RCS it is an overall app meaning it is related to several Google play services. I'll upload a photo of it. I have to reboot into normal mode.

RCS can be a real battery hog, but I don't know why. I don't have RCS on AT&T. Do you use Messages as your primary SMS? Open Settings>>Advanced and see if you can toggle off "Enhanced Features". Open properties and check if it is using battery optimization. If it is not, set Messages to battery optimization. You can always turn these back on later if the battery drain remains.

My battery life has been restored to pretty much the same as it was with 8.0. I also noticed poor battery life after installing the 8.1 update, even though they changed the way battery life is estimated with this update (supposedly). Something just felt off, but now everything feels great! I am fairly certain what changed is installing the Greenify Magisk module and/or the Google play services doze module (this enables battery optimization on the Google play services app). Not sure which one really made the difference because I installed them at the same time. However, there is definitely a major difference!!

In my experience that's really good.
Before 8.1 I noticed about 11% per hour during screen on use and about 0.33% per hour while on stand by in my pocket or a little bit better if it's just sitting on my night stand not moving while I'm sleeping (I think doze is more extreme in that situation) which seems to match what you are getting. Based on that screen shot I think that's like 8 hours screen on time over like 35 hours for a full charge. I've done a little bit better but not much. That's excellent battery life.
Since 8.1 it has dropped. Best now is maybe 7 to MAYBE 7.5 hours over maybe 26-28 hours. In my experience battery life always drops after an update but this case is far from the worst. I remember when my Nexus 5 updated from KitKat to Lollipop. The battery drop was awful and to make matters worse the battery life of the Nexus 5 was pretty bad to begin with.

So in my last reply I thought I was wrong about RCS Phone app being a conglomerate of several apps in the phone. For some reason I couldn't find the information I needed at that time. I wiped my phone and started over after posting this thread. I was trying to isolate the misbehaving app. I thought it might have been greenify actually, but no the drain has returned to a lesser extent though. Here's some photos of this RCS app from GSAM.

I'm not sure what is causing the drain at this point. I've installed Better Battery Stats to locate the wakelocks so I can ignore them through ADB.

Have you tried disabling RCS ? (Post #6). BBS is good for idle drain, active drain not so much. It's best run overnight without touching the phone for 8 hours or so. Pick the phone up in the morning and create/save a log file as quickly as possible. Post the log to the BBS thread if you need help deciphering.

I cannot disable it since it is comprised of multiple apps. You can see it in the pics on my last post.
