    Default Anyone pinpoint reason for battery drain?

    Google blames a faulty camera app which when opened never fully closes. They are fixing it in 4.4.3.

    But different people give different sources.
    In my LG phone, the camera app is perfectly OK. I use it. Yet the battery never drains.
    Somedays I doubted google play services. Then I doubted Internet app.
    All my location services are disabled. Some apps are disabled. I realized none of these were the culprit, since the battery was stable even when these were running.

    The battery graph is perfectly horizontal.
    Yet at some day, the battery magically begins draining. The graph shifts to a 20 degree slope.
    It will mandatorly lose 2-5% an hour even when idle.

    "Android OS" is the thing, the battery blames.
    What is this android OS. What is causing it?
    Any one have any clue? A news? A secret talk? Anything?

    PS:Fellow kitkat bars, the drain stops when you restart your phone and force close every app. This is the only solution working now.

    There is almost certainly no single cause, but different ones for different people's combination of hardware and software. And plenty of people aren't having any drain issues at all. Android OS does many different things to serve many different functions of the phone.

    Then why wouldnt it show who is making "Android OS" do most of its jobs when the phone is supposed to be sleeping.
    Presently, its blaming the kernel.
    If it does not pinpoint which app is making it do its job then clearly it is an OS bug?
    Isnt that kind of stupid.
    Suppose you use window media player for an hour, and windows OS which does stuff like windowing & kernel operations is blamed?

    Most of the drain is for the screen brightness. Don't know why its acting this way ??

    Is this a serious question?

    Android OS is what is running your phone and makes it work. Even if your phone is sleeping Android OS is managing network connections, listening for notifications, managing memory usage, running background processes, pinging for location, etc. All of these things require power from the battery to do. If you want zero battery usage then you need to turn the phone off.

    I think the point of the question was that before the 4.4.2 update there was only Android System, which is still there, and uses very little of the battery. Since the update Android OS is now there and is, in most cases, the predominate cause of battery drain.

    I think the point of the question is that before the 4.4.2 update there was Android System, which is still there, and has minimal drain on the battery. After the update there is now also Android OS which, in most cases, is the predominate cause of battery drain.

    No, I'm not a heavy user by any means, and I personally don't have a big problem with battery life post update. But, I can see where some people could have serious issues.

    Having the same battery drain problem. I didn't have to charge my phone during the day before the update. Since that it drains by mid day without a change in usage. I tried a factory reset but that didn't help. Also I'm having a problem with texts going through. The factory reset helped that a bit but most texts take 30 - 60 seconds to go through.

    Ever since 4.4 update, I have had bad battery issues. I listened to Iheart radio for an hour this morning (w/ the screen off) then exited out of it by selecting exit from the menu. I looked at facebook for about 10 mins, and received 4 emails. My phone was burning up all morning and dead by 1 pm. Any ideas? Seems like this topic never really has a solid answer.

    How about these?

    Can you see the constant straight line slope?
    it causes a 10 -12 % drain in 6hrs while being IDLE
    you cannot call that normal. because there are times when this problem magically stops and I get a straight line with only 1% drain in 6hrs, sometimes.

    android OS is doing something fishy.
    Any one explain

    A 6 hour battery drop of 12% would be 2% per hour, equating to about 60 hours of standby time, or nearly three days. I am not inclined to think that anything is truly wrong.

    Check out the screen shot provided by ejcrossl: They showed a chart that drained the battery 94% in 6 hours. That is a cause to be concerned.

    Seems typical for KitKat. Sometimes something is running that eats up a little battery. I see sometimes 3% an hour drain on idle, sometimes less than 1%.

    How is that not normal? The phone is on and running.. The radios are talking with the tower and staying alive... Processes are running in the background... All of that uses power. As golf said at the rate you're going that's almost 3 days standby time... That is just fine. .

    It could be a number of things, since it's listed under the Android system services..
    • Are you checking an IMAP/Exchange mailbox for new mail?
    • Do you have uPNP software running on your phone?
    • What are your signal strengths? (WIFI & cell)
    • What G of band to you use? 3G? 2G? 4G 3.5G?

    When your total mV usage is so low, something is bound to stick it's head up in the stats.. and besides, >2 days is pretty decent.. I wouldn't worry too much about it.. come back when your phone drains in less than 12 hours and we'll talk.. My Nexus 5 used to last 3,5 days.. now it manages to do barely 2.5 days on a full battery.. but then again, I've installed like 50+ apps.. so I think that's normal.

    @Golf and cappie.
    The reason I said 2% an hour is not normal is because
    1.I have tested the phone in airplane mode and still battery drains.
    2.With the exact same phone and conditions(same position, freshly restarted), I have obtained only 0.1% decay per hour even without flight mode on another day.

    Since the phone was sleeping, nothing must consume power ideally in airplane mode.

    If the same phone behaves differently on two different days. I wouldnt say the decay is normal because it is capable of doing better.

    @Alemuit.
    If the tower communication was the power sucker, "Cell standby" would be way higher.

    @Cappie
    And yes my phone and everyones phone will die in 3hrs if we use wifi for the full time.If I play asphalt then it will go from 100to15 within an hour etc. (No one mentions that they use all that)

    @Golf
    The other guys graph. I dont know which of the two you meant.
    Wifi is way above normal, thus his wifi was "turned on" despite him not using it.
    And his google search app is clearly a culprit. I suspect he has google voice or locations enabled, thus it is contantly using the microphone or pingin location.

    The second guy has bluetooth on. Haptic feedback is probably also enabled.

    Currently for those who face massive drain.

    1.Checking with a friend with same phone
    2.If the phone was ever updated or came out of box with same OS version.
    3.Did many another company phones have the problem.
    4.Auto sync may be enabled, causing massive update downloads during wifi use (plus wifi signal or phone signal may be too weak)
    5.Location services would have been enabled. It must be disabled.
    6.Haptic feedback must be turned off.
    7.Do not leave bluetooth, wifi, 3G data ON. Some people falsely believe that leaving it on has no effect unless you use it.
    7.Google Play Services unwantedly opens upto 5 services. Force close them.

    A solution to such a person.
    Freshly restart the phone with 100% battery. Then begin force closing every single app.(except core) The important ones will auto restart.
    If you have developer option enabled.
    Check >display cpu usage.
    Observe the recurring activities.

    1. The battery will still drain in Airplane mode, just not as much.

    2. There are always too many variables to consider when regarding conditions. Social media, emails, etc, if all are working properly, not getting stuck in a process (Facebook is nefarious for this). My current battery stats are 70% drain in nearly 12 hours (will provide a screenshot in a few minutes). A little low for me, but no big deal.

    The phone will always drain when on. Period. The OS will account for the drain. That is why when a device is left alone, the Android OS accounts for the drain because that is the thing that is responsible for the drain.

    The same phone behaving differently can be due to many things. Cell signal strength is a big factor, which brings your counterpoint to Almeuit; Cell standby doesn't really go up the charts unless the signal is not there for a large period of time.

    The other guys graph I was referring to was the fact that in the graph chart, you can see that the time on battery was 6 hours and minutes with the 94% drain. That is not a good thing. Yes, his bluetooth was on, but how long was it on? I don't know. It could have been on for 5 minutes.
    Google search is not the culprit as it only took about 7% of the total drain.

    How do you know haptic feedback is on?

    Observe the recurring activities.
    1. Checking a friend with the same phone: again, too many variables. Even on the same carrier, there are different quality radios in each cellphone, what does each person have connected to their phone, etc.
    2. Irrelevant. I am on 4.4.3 right now on a custom ROM and I have no excessive drain what so ever. Out of the box I was on Sense 6 4.4.2.
    3. Not sure what you are trying to get at here.
    4. Auto sync for me and many people I know, hasn't affected battery life. Yes this can account for it, but not the first thing I would look at.
    5. My location services are set to battery saving. No ill effects here.
    6. Yes, the vibration is a battery killer, but nothing to the scale of excessive.
    7a. Yes those will contribute to more battery drain, but again, not to excessive.
    7b. Force closing Google Play Services will last only as long as you don't open up Play. And even then Services will re open eventually. Force closing it continually can actually lead to battery drain as the OS will start the application back up.
