[Q] Android System is draining my battery a lot since I updated my phone to Kitkat

Before the update everything was fine. Now if I turn on the screen or listen to music the phone would awake (it would show that it was asleep in jellybean). When I turn off the screen and I am not listening to music then my phone falls asleep. Android system used to be awake under 20 mins over a 15-30 hr span now it can be well over an hour in 4-9 hr span. I did a factory reset yesterday already, uninstalled all of my apps and reinstalled them when I seen that the problem still exist. I googled the problem, but can't find a solution. Is anyone else getting a Android System battery drain like me.

Yes, I am having the same problem. I was told to do a factory reset but I cant even back up my phone with kies because it the MTP driver keeps failing to install and Kies says I have to use Kies 3 even though the Samsung Site says 3 is for the Galaxy Note..
Did you sideload your update or was it OTA?

It was a OTA. I did a factory reset already, but that didn't fix the problem unfortunately.

yeah I side loaded the update and I am on 100% stock no rooting or anything. My phone gets really hot all of a sudden and the battery starts dropping like crazy. I have none of the apps running so I don't know what the problem is..

that is odd. I was reading the forums on the sprint galaxy note 3 update, and people have posted pix of their battery stats. Their stats looks similar to mine. The people there was saying that maybe the problem would fix itself over a week. Im hopping it do, because I am really loving kitkat...minus this issue of course.

oh wow. You definitely have an app that is not liking kitkat. Your phone does not fall asleep when you turn your screen off. Im really trying to figure out why your phone is doing that. Im going to assume that "lookout" and "Malwarebytes Anti-Malware" are the problem. My opinion is that you don't need those as much as you think you do. they are most likely the cause of your drainage. My phone falls asleep as soon as i turn off the screen. Now i have 90% battery life with almost an hr of SOT left, and thats on 4g LTE the entire time.

Heres my stats new stats

I had alot of problems when on wifi, don't use it anymore and sticking with 4g. I'm at 30% left with just over 4 hours screen on. I'm guessing it's something either Google or Samsung have syncing more often on wifi, on wifi I'd be dead at 3 or 4 hours screen on time

Thats interesting. I haven't used my phone on wifi yet, because its a little inconsistent right now. If your phone is acting up while connected to wifi then it got to be something on samsung's end. You can end up with just over 5 and a half hrs of SOT if you stick to 4g and don't want any problems. I would keep testing how things go on both wifi and 4g over the next couple of days if i were you to see if the problems continues though. What problems are you getting while connected to wifi?

Another one of the major problems I am having is that sometimes my apps don't work. When i clicked on the camera it did not show up the app opens but the camera does not turn on. This leads to a major lag and when I try to press the home button it does not work. Then my phone's screen just shuts off and I cant turn it back on via the home button or the power button.
This also leads to the phone getting hot and losing the battery very quickly..
oh and btw the S5 does not seem to impressive to me..

I had the same problem at first. Waited a few days and it still drained badly. Then I went into startups and turned off a few of the apps I never use. Working fine now.

What apps did you disabled, and could you include a screen shot of your battery activity if you don't mind.

Same problem as the op. Android system would take alot and phone wouldn't sleep. But on 4g it sleeps. Could be an app I have I dunno. 4g is fast here so it's not a problem for me

i reset the phone and didn't install any apps and come to find out that its something that is already on the phone. I had no apps on my phone and android system and android os were in the top three that was taking up a lot of battery.

I recently had an issue with Android OS draining a lot of battery. I read somewhere that disabling stuff from Google sync that you don't use can help, so I disabled sync for all Google services except the ones I use, such as contacts, calendar, app data, people details, and play books. I rebooted and watched my battery for the next couple of days. And it worked. My battery life is a lot better, and Android OS is not using nearly as much battery as it did before. Perhaps this will help you guys?

***UPDATE on HOW TO FIX***
I HAD terrible batt drain with nae.. so bad that i left the device on the charger overnight qnd woke up to 35% batt... i got mad and reflashed stockish v6.. but.. batt drain was the same...
so.. here is what i did... i ended up flashing negalite r6 and the batt was so bad my phone would be dead within 1hr.. SO, FOR KICKS, i reflashed the MK2 modem and HOLY COW!, problem solved!!
im currently on negalite r6 ( a nae rom ) but using the mk2 modem and my batt drain problems are gone. in fact im getting great batt life. i didnt change the kernal or anything. i have flashed ktoonsez kernal over it, and it has not effected batt life at all...
in conclusion, if ur batt life sux, try reflashing mk2 modem.. it worked for me.. and yes 4g, mms, calls, and wifi work without any problem...
hope this helps

Battery and Mobile Data Problem

I have encountered 2 problems with my mobile I.e. samasung galaxy s4 i9500 runniny omega rom v20. They are as following:
1.I switched off my phone after charging it 100%, and when I switched it on after about 5-6 hours it had only 80% battery. I don't know how it lost 20% battery when it wasn't even on!
2.The mobile data both 2g/3g keeps ob activating itself from time to time even when I manually switch it off, I think maybe some app is doing this but I am not sure. I do not know how to check what is causing this problem, as this even causes massive battery drain.
I realised the data problem day before yesterday and the battety drain upon switch off yesterday, I can't help but think they are somehow connected but again I am not sure and don't know how to proceed to slove thr problem.
Any input would be extremely helpful, please reply soon as I am losing money over mobile data and am unable to carry my mobile away from charger for significant duration of time.

u can install wakelock detector and check it... whats going on

Hi,
First i dont have any idea about mobile data case.i always use wifi throught my wifi modem,but i can say a lot about battery matter coz i have a lot of case about it.infact my old battery was change at service with new one.
Well when i bought phone everything perfect battery draining i normal even low.but after i contuniuesly install application it getting bad.i mean not so bad but not like first time i use.Especially after i upgrade my android from 4.2.2 up to 4.3 then 4.4 it become worst.Battery drainin like crazy even like u said while phone switch of battery still drainin and without using phone i lost %10 sometimes %15 percent.İf i turn on not use (just on stand by with screen locked) i sleep at 10 and morning 7 already become 35% (From %95).Anyway i went to Samsung service many time.They complain to me that (Android 4.3 and above is take a lot of memory!!!and it effect to battery draining).Sure im not bieleve it.I know very well that Android cant effect up to this point.They change my battery.Still same.Nothing change.A few days later i start to thınk that one of my application cost this draining.Then i start to uninstall my applications one by one (especially visual applications like living Wallpapers,Clock Gadgets,Weather gadgets,dll).Finally i found the application which cost fast draining.It was "animated clock widget" and i never install it again.
So what i advise to you that uninstall all ur visual applications.Yeah maybe with this kind of application the visual on ur phone looking perfect but if u need battery in daytime it will be huge problem for u.For example just think that u install weather gadget and this widget need "GPS on" for see ur current location and giving u a weather data.if u dnt want to uninstall,at least buy one big capacity power bank and keep it on ur left hand as u keep ur phone on your right hand.
Hope it s normal again.Thanks...

That had been my first thought, but after closing all apps and not using phone even when it is turned on it drained only 1% or 2% battery in an hour, this was the case 2 days back. I don't think anything new is there on my phone since then; But still mobile data keeps on turning on itself and battery is draining even when phone is switched off. I am thinking, would a reinstall of rom be more helpful? Or uninstalling all apps one at a time?

You battery probably just needs to calibrate again. That's normal if you change roms. It should stabilize.

This is not only about installing application brother.Just think.U install one widget (Can be clock widget or "animated clock")that widget will only take place in ur widget menu,as long as u not use that widget.but after u place that widget on ur home screen,everything going to change.Like ur cpu,ram and battery usage.And no matter u use ur phone or "its screen lock mode",application still contunie to drain ur battery.(Generally people put some widgets to their Home screen for gettin cool home screen but as i told u,u can find other solution,if battery issue not problem for u.Like power bank.)So coz i had same issue,with my experience all i can say to u that first,try to install all widget application which install on ur system,Second be sure,after use application clear ur ram.
About Reinstall rom...i just did this process yesterday.i mean install room.coz i made a bad mistake while i root my phone and swap my memory.Phone dont wont boot even.and i downloaded Samsung Galaxy S4 GT-I9500 firmware (Rom) and install it with odin.Everything went perfect.I success the install original room than after some steps my phone boot again.it was looking just the day i bought.There is no more root access,not any application before i install,and same widgets and applications which i seen when i bought my phone.For sure it will solve ur problem for a while but it will repeat after your install process for your old application.

(Q) my phone won't go to deep sleep ?

my phone note 3 n900 with official Russian lollipop and with leaked one
i really start to hate the phone and i think of sell it because of this problem
i try factory rest and flash new ROM still the same problem even i try a new battery but the problem still the same and battery live get worst
my phone wont stand a half of day and screen on time in best time 4 hours and sometimes just 3 or 2 hours
what is the problem and how to fix it
see the screenshot

Looks like you've got a wakelock. Tried Wakelock detector? (If you're rooted.)
2-4h screen on time is very normal, by the way.
Have you tried removing the MicroSD for a while, if you're using one?

I donot use sd card and just 2 hours screentime i think it is not normal because i need to charge my mobile twice in one day

You Might Have Bad mp3 Files.Use Wakelok Detector As Mentioned.If You Find 1013 Audimix On Top Of The App Then That Would Be The Prob.Or It Might Be Simething Else.

any help please

Hassan, you can't get any help without posting the required info. Install BetterBatteryStats or Wakelock detector (as someone already said) and monitor what app/process is keeping your phone awake mate. Those screenshots can't tell anything about this issue.

Galaxy S4 Battery Drain

Hi guys, i have the i9500 galaxy s4, the last month the battery started drowning too fast. I've tried many roms, now im using "Resurrection Remix rom 5.1.1". The thing is that i charge the phone before going to bed and in the morning the phone is off with no battery. Sometimes GPSD consumes all the battery, sometimes SO Android, and now "Phone (Telefono)" is appearing.I've tried everything and readed every thread about this, but i still have this problem,and I just wanted to know if someone knows how to fix this, thank you!

It's an app or setting on your phone that is causing it. Your device doesn't go to deep sleep.

Hi,
Your phone doesn't seem to go to sleep like what @Lennyz1988 said. But now I'm focusing on "Señal de la red móvil" (Mobile network signal). So why your phone's battery drain so much? It's because your network signal (mostly yellow-colored), thus caused your phone to always awake with Phone app as the battery killer.
Your phone seems to searching for mobile signal continously. Make sure that network signal on your location is good. You can also contact your mobile network provider for network troubleshooting in your location.

You probably need to go to an authorized service center. But how can it get damaged so fast? Did you disconnect from charging cable before battery reaches 100% and connect charging cable when battery is above 10% frequently?

Really I don't know, I bought it used just a week ago from a person that gave me also the receipt from 01/08/2016. I don't know if this is battery related or any other problem, I'm just feeling to exclude software problems as I tried everything (also rolling back to a previous update or trying it without SIM, apps, sync, AOD etc.)

Can you describe your problem ? Like are you having problems with very low sot or very hot device?

Sure u can. Its just not as easy as popping the back cover. The s7 edge and s7 is actually easier to do than the s6 series. Look at ifixit.com and see if they have oem batteries. They will have a tutorial for the process

Actually it seems to suck away my battery life specially when screen is off. No matter if it's only on stand by with wifi/radio on or in airplane mode, my battery drains like I've never seen before on standby.
Stranger thing, the problem isn't that big when screen is on (obviously battery drains faster, but not by lot more).
Device goes hot locally, specially in the mid-right side, when I use data and I have bad signal; when I'm calling I noticed that most of the times I lose the call, or from a certain moment the other person can't hear me anymore if I still can hear him.
I don't know if it's battery related, a radio issue or any other problem. The fact is that it drains my battery even in airplane mode or without a sim installed.

When i installed an app through apk and i didnt know it was rogur until my device started heating up with no apps in the background. So i used malwarebytes and found malware. After removing it and rebooting it the device calmed after. But then again this might not be your fix.

Hi all,
This is the situation today after 3h10min of battery, -30%, at home with wi-fi (no GPS, no bluetooth, no AOD, no NFC, no sync) and only 50m of screen on.
I also deactivated some bloatware and other apps from App manager and Package Disabler Pro (Google app, Word, Excel, Powerpoint, OneDrive, OneNote, Skype, Oculus, Samsung Gear VR, Knox, Samsung Game Center, Om Customize); also unchecked options to send statistics to Google and Samsung, and all the other stuff I read from the topic "Temporary battery fix".
The situation is still the same. P.S. I'm on latest BPJG (unbranded) with November 1st patch.

Might not be the battery at fault. You have no standby/sleep, something is keeping your phone awake. Your Android System looks to high. If you have the receipt couldn't you send it to Samsung?

have you tried to factory reset it, if that doesnt work try to flash newer firmware like nougat or newer version of mm with odin

I tried factory reset but still problem persists. Now I'll try with Nougat official beta update flashed from Odin to see if I can fix it.
