    I had an update last night so I updated my phone but it's still on 4.4.2 kitkat the update was just a stability update but my phone has been fine until now where the android OS is using a lot of battery power & my phone is hot. The battery has gone down really fast too which is not normal. Anyway to fix this?

    Have you done a cache partition wipe? This can sometimes help after a system update. Reset: Samsung Galaxy S 4 | T-Mobile Support

    Yeah I've done that. I turned it off let it cool down for about 15 mins then booted into recovery & wiped the cashe. Had to stick it on charge after that screen shot.

    Is it normal for Lookout to use so much battery?

    No that's not normal either usually it uses between 3-4% or sometimes it's not even on there.

    Maybe that's the problem. Stop it for a while and see If the problem persist. Android OS is related to background processes.

    Didn't no that the android OS is related to background processes. After taking my phone off charge it seems to be acting normal but will see when it reaches about 40% as that's when trouble started.

    Bad wording 😊

    Android OS is the kernel and tons of processes are included. I meant that that the high percentage of battery in Android OS could be related to background processes.

    Oh ok at least I no now. At the moment android system is at 21% but all seems to be ok. Maybe it was a little glitch that android OS was using so much battery.

    An even higher percentage now look at this. Can't believe it's 62% the highest I've ever seen it. Normally it's not above 20%

    This is just an incidental observation, but is your cell signal that bad all the time? That could contribute to your battery drain, but it shouldn't contribute to the OS battery usage.

    Yeah unfortunately my cell signal is rubbish always has been since I joined EE. I think this android OS thing is due to the update I did the other night as it was fine before. Maybe if Samsung hurry up with the 4.4.4 update it will fix it.

    Don't really wanna do a factory reset either. Will loose to much stuff.

    Let's try to find the culprit then .

    You're going to need more detailed battery stats. Download Gsam (free and no root needed ) and have a look at battery and cpu percentages. Check the wakelocks, normally very cryptic but you could get lucky.

    You are going to need to charge your phone after installing the app. Post the screenshots after some use (battery at 20-30%) and let's see if something pops up in the stats.

    Mine is doing the same thing. I used to get a whole day out of my battery with moderate use. Since the update, I now get maybe 4-5 hours. At first, I thought it might be the battery crapping out, so I ordered a new one with no luck. Today, after 2.5 hours with only 30 minutes of voice calls, it was down to 45% so I had to start charging. Ridiculous...

    Glad it's not just my phone doing this.

    Will download Gsam tonight after work then I can charge it & report back here with some info hopefully after I've used my phone normally for the day.

    Same problem here. I uninstalled a couple of relatively new apps, and then a couple more. I did a factory reset Sunday, and now my battery life is awesome again. Kind of a pain to do the reset, but in this case it was totally worth it.

    Factory reset will not help if you are having the same issue as I am, since that leaves the Android update intact.

    It doesn't look so terrible now. Couple of things.

    Lookout is no longer there, did you stop it?

    Signal still looks weak and, as Diddy said, some drain must come from there.

    Do you have location on? High accuracy? This could be one of the possible reasons for Android System being a bit high.

    Are you using an SD card? If so, do you have apps in it or just photos, music ...? Try avoiding having apps in it. Maybe you should run a battery cycle without the card and see if there's a difference.

    How many hours of SOT did you use to get before this problem? I'm not sure if 3:30hs and 20% of battery left is much less than expected in your phone or not.

    No I didn't stop Lookout it just disappeared from the battery stats screen. My signal has always been weak especially when I go to work for the 3 hours it's very hard to get signal at work.

    I do have location on but I set it to medium accuracy as when it was on high it kept turning on the GPRS which I didn't like.

    I do have an sd card in my phone with pictures, videos & music on it but one of my apps moved itself over to the sd card.

    I dunno what SOT is but 3:30hs is about right for my phone before the update. Maybe I need to wait for the OS to play up again then post results.

    Looks like things are settling down on their own after the update. SOT means Screen on time, how long has been on.

    There are lots of people complaining about kitkat having problems with sd cards (battery issues, missing icons ...).

    Try to keep the number of apps using location to a minimum that cover your needs. Check the settings in apps like Facebook and decide if you really need that (I'm not a big fan of the FB app and I just access from the browser).

    Ok thanks will keep that in mind. If i come across any other problems then I'll be coming back on here. Seems to be all good for now.
