[Q] Maps battery use

I was looking at my battery use stats for the past couple days, and I noticed that Maps is the #1 user of battery on my phone. Funny part is that I never launched maps, and haven't used anything with a map since I last rebooted my phone. Is it possible that Maps is in reference to the GPS being used, or is there a way for another application to be using the Maps frameworks, thus causing it to show up under battery usage?
It's not necessarily causing terrible battery life, but I find it hard to believe that an app I haven't used is using more battery than the screen.
Thanks!

I'll keep an eye on that. Speed test had been number one on mine lol

I think it's in reference to the GPS. I have mine on so my weather is as accurate as possible and maps is a big user on my phone.

I've had the same exact problem. I can't figure out what is turning it on.

I think I am also having this issue.

Wi-Fi power drain?

Maybe just new to the tablet but.. Wi-Fi sucks battery like no tomorrow. Maybe it's the battery monitor built in that doesn't read it right but when Wi-Fi is using 70-80% of the battery (by far bearing screen). Just curious if anyone else has the same thing. Get great battery time with it as long as I'm not paying with it, and in standby it uses next to nothing. Just when on the Wi-Fi goes into overdrive.

My understanding is that the built-in battery monitor just isn't accurate....

Ok cool. I figured that was the case just as it is with my phone. Just had an older phone that was really accurate so just use to that.

Google Maps Wakelocks (not Latitude)

I've been noticing higher than normal standby drain on Synergy for a while now. Using BetterBatteryStats I noticed Google Maps is the culprit. Currently, I have 9 hours since charged and it's been sitting idle next to me while I slept. AlarmManager accounts for 2m23s of wakelock, but a staggering 1342 counts. Under alarms, com.google.android.apps.maps and com.google.android.location are the top two, accounting for 315 wakelocks (everything else is another 150 counts). If I'm on Wifi, these numbers blow up and I can see tons of wakelocks even on the built in battery graph. Oddly my battery life is about the same in both circumstances. I notice most of the Alarm events are unaccounted for, so whatever is causing them must be hurting the most. Also, when on Wifi, most of my Partial Wakelocks are caused directly by Google's location services, usually with tens of minutes of wake time and hundreds of counts in ~16 hours. It doesn't sound like much time, but it's the counts that are killing me, I think. I end up with ~90% deep sleep when I don't touch my phone. I lose about 1.2% per hour or so, and I know the phone is capable of less than half of that.
I've disabled Latitude, made sure my CPU was set back to 1.51 GHz (it defaults to 1.9 GHz on Synergy), and my GPS/Location options are all enabled. Switching to a different maps/navigation app isn't really an option for me.
I've found posts discussing this, but typically it's caused by Latitude or just gets chalked up to a bug in Map. If it really is a bug, it's been around off and on for about a year and I have a hard time believing Google would leave a battery draining bug in one of their main apps that long.
TL;DR Is anyone else getting lots of wakelocks cause by Google Maps? Does anyone know how to fix it or narrow down the cause?

I'm seeing very similar, haven't seen a good explanation yet.

I am having a similar issue. I am starting to think that it is related to Google Now. This isn't meant for ICS and I think it is causing issues. I am going to turn it off for a few days to see if anything changes.

Yea it sucks I had major battery drain from maps for no apparent reason either on wifi at home

I noticed the same, I kept Google now off with this last nightly I installed and I'm getting a little under 1% an hour with screen off and wifi on. I think my battery is also better without juice Defender or green Power.

Yea, +1 on killing Google Now, although I just killed the location history option (under latitude and google now, if I recall) and saw a big decrease in battery usage/wakelocks from maps.

I decided to just freeze Google maps. So far so good

For me, I narrowed it down to the Facebook app. When I uninstalled it, my Maps Wakelocks stopped right away.

Good tip. I just installed Facebook for the first time last night, so for me at least, it's not the cause. I do remember seeing a location option in the settings, so you may be able to solve that issue without resorting to uninstalling.

If u think it's Facebook u can download friend Caster if I'm not mistaking that app doesn't use gps every time u open it like Facebook does

I've seen this when I have the Google location service option enabled. It seemed better when I disabled that.

My standby time is now amazing compared to before with maps unfrozen

Why is wifi killing my battery

I'm on stock jelly bean and only getting just under 3 hours of screen on time. This is horrible and besides screen drain I'm getting most of the other drain from wifi. Anyone know whats going on? Any help would be greatly appreciated
Edit. After Google I see it's a known issue

Try killing off Google maps if it's running.
Shut blue tooth and GPS off if not using them.
These couple of things might help.

One thing to know and remember: The percentage mentioned is not how much of your battery it uses, it's how much of the current battery usage belongs to the app/component.
Running any live wallpapers? Auto brightness? Which power-setting mode? Location services?

i am having the exact same issue, balanced mode, 35% brightness, no gps, bluetooth on etc and having only 3 hours on screen? Unfair because this tablet is perfect other then that

I would assume it's normal, it might use more than it's supposed to but wifi and screen will usually be the worst sinners, depending on what use of course.

Thanks bud. It's definitely not normal. After doing research I come to find out its a problem with Asus code. Wifi should never be anywhere close to being reported by the battery use stats. Hopefully we will see a fix sooner or later

If I am not mistaken an update came out either yesterday or today that had the WiFi issues noted in the changelog. Check the ASUS website.

Android OS eating battery?

No, i'm at 6%.
something you are running is causing the activity to spike.

Percentages like this are meaningless without something to compare it to. 40% isn't unheard of if you never use the phone, for instance.

I was having this issue yesterday. I installed FAUX kernel and it went away; screen: 28%, mediaserver 16%, rocket player 13%, android os 10%. Yesterday at this time my battery meter was 40% ; today 67%.
That could be coincidence and not correlation though. If you are up for the challenge, a custom kernel could help.
However, like vincent law said, it's all relative. If android os is 40% and your battery is at 95%, that's not really so bad is it...

When android os is high... It's an app keeping your phone awake 90% of the time

Reboot when you see this happening.
I've seen it once before... I didn't think to check OS monitor before rebooting to see exactly which process it was though.

I have this problem. Anyone got solutions to it?

Try disabling some location features in Google now. I found the traffic cards to give big battery drains in Android OS. Or you can check which in settings - double slide down from top > location, to see which app is using the highest request. Google play service was usually high when I had huge android os drain.

+1
I have also noticed that at times google play services has a huge drain on the battery. I was wondering if play store setting had anything to do with it. I have mine set to " do not automatically update".

I have both facebook and google search on low battery use. For Google location reporting, I only have location history turned on. I don't know if this helps.

I start getting the same issue since yesterday.

I've also been experiencing the same issue. Started a few days ago. Checked tonight right before I put my phone on the charger after a full day of use, and Android OS had 9+ hours of awake time. It's driving me crazy and I can't figure out what is causing it.

I am so disappointed!!! I have the same bug. I had it on my old Phone (Samsung Galaxy S). I flashed 3 different firmwares on my i9000. Nothing helped. Now I bought the Nexus 5 and after one day it starts again
I went to bed with 97% Battery. Woke up and it looked like this:
It is stock Firmware with no changes. Maybe it is because of my google account? I am using the same google account for my nexus5 and i9000.

Check your WiFi connection. I don't really know why (yet) but sometimes, being connected to certain WiFi networks increases Android OS usage. This happens a lot in my college's network so I believe it's a problem with that, because it does not happen at my home's WiFi. You could try disabling WiFi in the different networks you use and check which is draining.
Hope this helps.

Yes I had this problem. I flashed factory image and enable high accuracy location AND reporting. My problem I pinpointed was Google Now NOT refreshing.
It would hang there trying to update and without location it didn't have anything to report and it would eat battery. I would force close the launcher and notice the wakelock stopped shortly, to return to Now not updating.

I found a way to prevent the Play Services and the Android System from eating my battery.
First I noticed that it was only happening, when the location services were enabled, and then I found the App Ops App for KitKat.
All I did was disable the rights for those two Apps to use location and to keep the device awake.
I'm having the location services on - and working in 4sq, Maps, etc,.. - and no more drain.
Maybe you can verify this?

Try this
My Android OS is at 3% after 19 hours.
Google services not enough to even show.
Battery 75%.
Light use 55 minutes screen time.
Google auto sync off, i sync when i need to.
I don't let play store check for app updates .
I turn location on when i need it.
I use mostly wifi some LTE
Unchecked wifi scanning always available.
Keep wifi on during sleep
Minimize battery use when wifi is on is checked.
I refresh my email accounts when i open them so it's not being checked automatically.
No battery or services complaints (Google services is so low it doesn't even register), give it a try?

The problem is definitely caused by the Wifi! I am using my College-Dorm-Wifi over night. When turning it off, the battery life is normal.
But turning off the Wifi is no solution! I don't have data so I am only using my phone in college networks
There musts be another way.
