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.

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.
