    I notice in your screenshot in your original post that you were on WiFi...take a look at Settings>tap on the 'Wi-Fi' and on the next screen, tap on the 3-dots lower right (overflow), tap on Advanced>be sure Network notification is un-checked so that the phone won't continually be awake while it scans for open networks. If you ever really want to scan for a short time go in and check it temporarily.
    I only have WiFi notifications and WiFi optimization checked on that screen (and only seldom use WiFi).

    yeah on my phone, the advanced settings for wifi are completely turned off. that does save some battery for sure...

    Here are two screenshots from a day with heavy use:

    Absolutely true. I have a strong signal both at home and at work, and with my usual phone habits I can go two days before having to put mine on the charger. While visiting family recently, however, the signal was poor and it was hard to get through the day without having to charge once and sometimes twice. It made a huge difference.

    My Android OS usage is around 50%, I uninstalled facebook and it dropped to around 30%. After a few days my Android OS usage went back to it's normal of around 50%.

    Seems like uninstalling facebook works but only for a short time.

    Power drain is not straightforward, and the percentage vs. absolute numbers trip a lot of people up (say the OS uses the same amount of power when idle or active, but if the phone is idle it will be a higher percentage of the overall use - not that it used more power, just a higher percentage). I don't think you can compare this to a tablet because the tablet is not as concerned with the phone part of staying alive it has a bigger battery and stronger WiFi, and comparing to other phones is not straightforward since this one is listening all the time for the magic "OK Google now" phrase, pushing up active notifications etc. The phone is never truly idle, unless it is powered off. Also, as many apps move to Google cloud messaging (Where their servers send notifications to your phone via Google instead of directly to their app), you are likely to see the OS carry more of the burden on your phone. For me, as long as I am getting the total hours I expect, I use the battery details to see if I have any rogue apps, or to understand how the phone is being used.

    You on 4.4.2? If so, there is a bug with the camera where if you open it or if a 3rd party application opens it there is a loop that generates high OS. I read this on the nexus forums and it seems that a number of moto x's are plagued with it as well. It has been reported that rebooting the phone at least once a day does fix this temporary. However, I think there are other services like chrome and Facebook that eats battery as well. I am unsure if switching from dalvik to art does help. I think that i read in a different thread that tom switched to art and started getting goof battery. Dont quote me though because im on at&t with 4.4. I do know if I receive a missed call with assist on that the CPU of my phone keeps constantly on. Anyways, I think the problem lies with the android OS more than Motorola's software

    Yes but that should be listed under cell standby... Like I've said before. I think it's a conspiracy to hide cell standby when ur not getting good reception to keep the perception that moto radios are better.... I get about the same reception as I did with my s3...

    Samsung does not make weak radios necessarily. HTC does though. When I had a Droid Incredible 2 the radios were so weak it was crazy. It was a very good phone though.

    Yes I am on 4.4.2. Are you talking about the mm-qcamera-daemon? If so I haven't had that issue and with chrome I just disabled it and still get the 50% Android OS usage. Kind of just gave up at this point and hope Google releases another update that will fix this.

    although my X Hasn't had the notorious sw glitch (Yet) i have noticed today that this morning i rebooted my phone once, and when i was done with work at 3pm today, unlike yesterday , my battery was only drained to abolut 85% battery. The screen shot i am providing shows that my Android OS used about 35% battery which is a little less than yesterday although not by much. Has anyone here ever experienced that before. I mean last week at work. i had more battery drain one day, but the other days of the week i had less battery drain and this as without rebooting the phone at all.. Again, It's just interesting and i'm curious about it....Moto X: Why is my OS usage so high?-screenshot_2014-03-12-15-09-44.png

    The way I read it, your phone used about 15% of the battery's capacity through the course of the day and that the operating system used only about 5% of the battery's capacity between your reboot and 3pm. Looks outstanding to me.

    yes today it was phenomenal.. Yesterday for some odd reason was a different tale ..Explain to me how you get that reading from that screen shot though again please. as far as the difference of what changed, i didn't change anything which , as i've mentioned, is the weirdest thing about it..all i can say right now is oh well, i love my phone so oh well...

    Okay. 85% of the battery capacity is left after about 8 hours and 40 minutes off the charger. That means it used 15% of the battery capacity in 8 2/3rds hours. Roughly, that's less than 2% battery usage per hour. That tells me that during that 8 hours you, generally, likely had a good phone signal (near one or more towers) and didn't use your phone for much. At that rate, you wouldn't have to recharge your phone for over two days. I can't see anything to complain about there. There are so many factors that will use up battery charge at a quicker rate that there's no easy way to point at one thing that pointing at one metric and saying it's the culprit. The day before you may have used your phone more or were in a location that had worse reception or maybe had an app that was doing something that kept the phone at a higher clock rate (e.g. busy). No way to tell without getting far more detailed information than these screens show.

    I am not an Android engineer -- heck, I'm not even an Android programmer -- so I don't know that my analysis is right. However, I do know that the operating system (OS, or in this case Android OS) is always running! It only stops when you power the phone all the way off.

    Oh absolutely and i completely agree with you. I love my phone and the battery and the very clear speaker on the back as well. It was necessarily a complaint, but rather more of an observation of course. That explanation does help, and I had a funny feeling about it, it's just a different way of viewing how to analyze the battery used up on y our phone .. that's' all. Yeah, Usually I'm close to multiple towers, and at work, I don't use my phone as much as i used to. I do use Bluetooth a bit but still that doesn't affect the battery nearly as much. Thanks for your assistance!

    I have noticed that when I have several notification waiting for me to few them through the active notifications, after I go to . Check the notifications, at that point my battery will say 50% usage coming from Android OS... Does that mean the active notifications are what is draining my battery? Doesn't make sense. That's supposed to save tons of battery power.

    The 50% all depends where your battery level is. If your battery is still up high like 90% then 50% would be 5% actual battery used. but if its 50% when your battery is low then you would have a issue.

    If I've interpreted correctly what I've read about Active Notifications, there is going to be some OS "awake" function going on all the time, otherwise it wouldn't be 1)providing you with the notices on the screen; and 2) listening for your "OK Google Now" prompt.

    Yes, AN is supposed to save battery, but relative to what? I'd say it saves it relative to other phones that don't have the dedicated processors for those sensing/notification functions, like the X does. There are apps coming out that imitate AN for other phones, but they likely require the more power-hungry processers on those phones to run them. Or that require you to actively awaken them (hence powering up the main CPUs) to find out what the notifications are about. I may be misinterpreting the capabilities of some of these other imitation-AN apps, so anybody who knows differently please correct me.

    But AN and Touchless Controls are still going to use battery no matter what, and that likely involves some OS processes.

    Haha yeah no i gotcha about that. I don't know, I guess I just find it weird that's all. Its weird, because there are some days when I get a lot of notifications via active notifications and my battery doesn't drain as much. However, today and yesterday and dreamed about the same right but I was at the factor because other day they have amazing battery power that last for a solid day. Oh well....

    My Android OS usage is still high, in the high 40% to low 50% but now it seems like I can actually get a full day out of the battery. Haven't changed my usage, just some apps doing updates. Not sure if that has anything to do with it.
