[Q] android os battery drain

I have i9500 cm11 ROM nightly. Version 20140105 and it drains battery. 43% is android os. 7 hours and 5 hours I didn't use the phone. What should I do?

When I had issues, I installed GSAM battery monitor and got more details. Shows when it was using more data, was awake, was using phone signal or wifi, battery temperatures..... For me it was some media files that were not processing well, so I had to drop in some .nomedia files.

Try to download Wakelock Detector from the Play Store and see the root that causes it. For example, the last time with stock rom, I have issues with Google Play Services with NIPcollector issues that keep on waking the phone without letting it to fall into deep sleep causing a huge battery drain. The solutions, Wakelock terminator, can be download in Play Store aswell. The free version of wakelock terminator only let you terminate 1 services which is just enough for my case. If you have more than one services causing lots of wakelock, consider getting the donate version.
Do use Greenify to hibernate unused apps aswell, it does really helps. :good:

if u are looking for low battery drain then stay away from custom roms especially cm based roms.
not only they drain the battery fast because they are badly ported or whatever but also they are missing samsungs energy saver mode which does save alot of battery. (only enable cpu and u will never notice its on)
so if u really want to use a custom rom then atleast get a tw rom.
my best experience for best battery on my s2, s4 and note 3 is original stock rom with bloatware removed, energy saver mode on (cpu only) and xposed+xblast module.
that way i got best battery on my s4 (almost 6 hours on screen time or 3 days standby time), all tw features and all features i want from a custom rom.
also on every android phone in my house i had a battery drain while having wlan on in standby mode.
i noticed this not when having the screen on... only like at night when the screen was off.
this took me about 1 day standby time... so ihad only 2 days standby and not like now 3 days.
lost like 10-15% every night while doing nothing. now its 1-2% every night.
this wasn't the fault of any apps installed or anything else. only thing which help me with this was buying a new router.
after researching which one would help me with this problem i decided to buy this one. cheap and also very good and alot of settings.

other then that NEVER use geenify or any other battery tools. they will not help at all...
only app that could help is betterbatterystats.

I'm glad you are speaking only from your own experience, because many people have had different experiences. I get as good as or better battery life with CM11 over TW on my i9500. Many others have said the same.
BTW, CM for the S4 is not a "port."

1) Download a newer nightly. Lots of progress has been made on CM11 in 4 months.
2) Backup your data, do full wipes and a clean install.

cmon man. it's ok if u like cm and all. thats ur thing.
but don't say u got same as good battery like on tw rom... then u ain't know what u talking about.
if u say something like that its clearly that u never had a good running system and probably cm on ur phone since u bought it.
but i agree he could solve that high android os drain due a fresh clean new install/full wipe (probably even with the same version he has on the phone right now)
battery would be still alot worse then on tw roms with stock kernel

Check this. If it is the same issue, it doesn't depend on the ROM, but on the carrier.

thanks for helping guys. I have found out that the music player doesn't give the phone to fall into deep. i want to move to be not system app and to put it on hibernate. how can i check if the app "/system /app mover" works on rom cm11 ? cant it break my phone?
thanks

Clicking the battery in settings will give some information.
I had the problem in past week (i9505 S4 running stock 4.3), where Google Play Store inexplicably was unable to connect to the server. As a result, it kept trying to connect and fail repeatedly, and draining battery severely. Tried all the fixes to reconnect Play Store with server to no avail. Ended up doing a hard reset, and this fixed it. Battery consumption now back to normal.

Note 3 and Gear 2 Battery Life

I just purchased the gear 2, however im getting ok battery with the gear. However my note 3 battery is draining like there is no tomorrow. Any ideas or suggestions that could fix that.

I had similar issues with battery for my n3. What I did was rooted and installed a rom I went with alliance rom because I have the best battery life and no issues with stability. Also I keep my brightness off unless I'm outdoors and use my phone. Also recalibrate your battery helps I installed battery calibration app it removed the battery.stats.bin file for you. So you charge 100 then hit calibrate and your done it only needs to be done after flashing a new rom. If you need instructions on root and other things I mentioned just ask. Plus there are tons of useful discussions on xda on this very topic. Hope that helps.

Do we really need Greenify on a phone like this ?

Hi guys,
i've been using greenify since as long as i can remember, especialy on my Galaxy S3 it helped me out pretty good.
i bought the donation package for the note 4 so i could hibernate system apps to.
but now ive been thinking.. do we really need an app like that on our phones ?
i've been experimenting with S voice and when i enabled greenify service it doesnt give me a voice feedback and i have to say Hi galaxy 2 times.
so now i disabled greenify, but i would like to know if someone know's if greenify really makes a difference on a phone like this.

I installed Greenify and bought a spare battery for my Note 4 when I first got it. I've since uninstalled Greenify and only switch my batteries once in a while so they stay fresh.
I get such great battery life that my old battery-savings methods from my S3 don't really apply anymore.

Okay thanks ! that's the same i was thinking.
after a full day of using the phone (16 hours) i still dont get under 40%
how many SOT do you get ? assuming you are not rooted

Hi,
I dismissed it because this is the first smartphone that give me enough autonomy till the end of the day. If I need more autonmy with the two options that Samsung pro ide natively, power saving and ultra power saving its enough for me. I see other mates who also unistall it after using it because the difference is residual almost goes worst using it. That's what they say.
Greetings.

I personally don't use greenify on my note 4, used it on every phone earlier, just don't feel any difference anymore..i usually charge every night, and almost all the time the battery is >30% With this much battery left, greenify would just be an overkill.
All in all, I am in love with this note:angel:

I also uninstaled it didn't see any difference

I have a Samsung S5 Prime that has same hardware as Note 4.
I was wondering if remaining on KitKat for using Greenify and Amplify or just go to Lollipop.
You say to go to Lollipop without any doubts??
Can you please explain why in the deep?
Thanks so much.
Cheers.

Hope that i can help yo uwith this.
You could also install lollipop to see if you like it first.. but im going back to Kitkat !

I had the free version of Greenify on my Note 4 and didn't find that it gave me any better battery life. After a while I bought the donation package so I could stop system apps as well but I found that made my battery way worse because those system apps would always restart themselves. Greenify would keep stopping them when they restarted and it really ran my battery down. Currently I do not even have greenify installed and I get over 5 hours screen time so I'm happy.

I too would love to know by an expert does greenafly help or not.

Install better battery stats and post a dump file after it sleeps for a few hours.

Could be a lot of things. Do you have weak signal? It could also be apps syncing and what not, I'm not sure that would get attributed to the cell network though, it's still worth checking. If you figure it out let us know but otherwise post the dump after it idles for a few hours, that will tell us for sure what the cause is.

System service drain

I was convinced on the forums that my system service drain was regular until I took a look at my buddy's phone , he has a le s3 with 2 sim cards and his system service doesn't normally go past 80 mAh on a full charge . Something has to be wrong

This is a screenshot of my sot when I first got the phone

8 hours of SOT is really good. You can try installing Wakelock Detector to get a different perspective. Also, anything that uses accessibility services may harm battery life. Another thing you can do is go to settings-permissions-autolaunch and disable autolaunching of apps that don't need to be running all the time. You can see what apps are currently running in settings - app management. One last thing is that your signal strength isn't that great, so it may just be how it's supposed to be.

I'm in the same boat as you, only I'm running OmniRom. But yeah, had 8h sot, can barely make 6 now, android system is my second biggest drain, with 2+ hours of cpu usage.

I have tried and I have found that 7.1 to 8.1 do not have the best battery life.
I personally have been aopk 6.01 and been getting great battery life.
I did do a stress test I did gaming and blasting next radio 21 minutes use only 6% of battery.

I've tried everything , disabled all apps in auto launch , tried it with airplane mode on , enabled background resource control . Never go past 7 hours max screen on time . My screen brightness is usually very low throughout the day

What are all of these services ? My buddy has none of these

You are running stock I take it.
Different ROMs are going different services like you show.

Turned on battery assistance at about 80% , battery life drastically improved

This is now ridiculous

All eui is in the rom.
I have no problem with custom roms. (Omni,Aicp,Lineageos etc.)

I don't see the big deal you have 3 hours 57 minutes on screen time and 50% battery left you will get almost 8 hour screen time on that is well above average!

Went through a hard 12 hour process , finally unlocked bootloader , installed twrp and running lineage . Going to be testing battery life

I have the same problem with Eui rom. As long as the display is turned on, the system service will exploit the battery. Nobody knows that?
There are no such problems in custom roms.(Aicp,omni vs )

Flash Magisk and try Greenify4Magisk. It's gotta be some third-party app you're running, or you have a bad cellular connection. Are you getting full signal on your phone? Do you have LTE running as well?

I haven't installed many apps , just the basics like Snapchat WhatsApp Twitter and Instagram . I tried to flash magisk but that would mean uninstalling super su . I normally get around 3-4 bars but I don't use cellular data . I have Greenify but it doesn't seem to be doing much
