guys ever since the update, i've had a horrible battery life because of kernel and system_server processes. Does anyone knows whats the cause or how i can fix the issue, i've tired "Wake Lock Detector", "GSAM", everything i can think of, even "show CPU" in the developer option, i cant seem to find the cause of the issue. if nessary ill add pictures to show the results that am getting
sorry, completely forgot to mention that am using a S5 Active(G870A) and updated to 5.0 (OC5) using @muniz_ri version http://forum.xda-developers.com/att-galaxy-s5/general/how-to-update-to-g870aoc5-5-0-keeproot-t3083841
If screen is on alot not much help here; However, I am using my deductive reasoning & will suggest deep sleep battery saver. Makes my phone stay in the 90%s if my screen is off awhile. Firefox beta uses battery until you physically exit out I've learned. Last thought for now, kernal tuner. Put 1 CPU governor to powersave. Not sure if it matters which? Mine is CPU1. Hope it helped.
My Samsung S5 Active. Yes I read pages. Thanks
I wish it was the screen but the screen only takes up 3% of battery usage while android OS and kernel takes up about 50% combined and I have no idea what to do because "show cpu" state that system_server and media server is the culprit

Install better battery stats and get an idle dump so we can see what the exact issue is.

I'm getting some fairly significant battery drain from something called "Modality Service." It probably wouldn't annoy me so much if I had any clue what it was. Anyone seeing anything similar? Any idea what it is? My searches on the matter are coming up empty.

On and off through the day.
Interestingly "Modality Service" hasn't shown up at all today, with 7.5 hrs on battery. It's pretty intense when it does though, and I'm still deeply curious.
I saw this on someone's screen shot the other day, googled it and it didn't return anything related to it.
I think the use who posted had data disabled for most of the battery cycle, maybe it has to do with that? Not sure though

I have the same issue. I noticed it yesterday, I had very low usage and it was the top battery user. I clicked on it and it said it used GPS for the whole time my phone was on but I have GPS off, so that was odd. Also I checked into BatteryStats+ and it didn't even have it using my battery. It appears it isn't affecting my battery life because my CPU usage was only about 2s. I have no idea what it is though. I posted this on G+ and a guy replied saying he was on the phone with Motorola multiple times and ended up getting a replacement. I'd prefer not to go that route...
I too just noticed this last night and today. Last night it was showing using 48% of the battery and today using 38%. I found the service and force closed it. Not sure what it does or is.
Do you all have moto assist activated. It's only an issue for me when moto assist is trying to determine if I am driving. If I disable the driving portion, modality service never appears

My Nexus 5 is coming in the mail on friday, and I was wondering if anybody found a good kernel/rom + settings to achieve the best possible battery life? Ive been doing research, and CM nightly + chaos kernel seems like that might work.. any better recommendations?
maybe a certain kernel + stock rooted??
anything? my main concern is battery life... but I also need performance.. not extreme performance but i dont want a laggy interface just for better battery life.
maybe also some undervoltage settings?
please people give me some recommendations or even your personal favorite and why.. thank you.

heres exactly what you are looking for http://forum.xda-developers.com/showthread.php?t=2477889
experiment a little, try out different combos, thats the only way that you will find the perfect combo for your phone, and for your needs. everyone uses their devices differently, has differing needs, and each device reacts differently to every rom and kernel. whats perfect for me can be terrible for you.
Just passing thru....see the post above mine. Thanks

My device is not very old. It's about 1 year now and battery isn't as good as it used to be. When I got it after school I had minimum 50% no matter what I've been doing and atm it's 24% which is disturbing.

Check for battery health in 7378423 to see if it had any wear out in battery capacity. Mine is 31460 (1+ year, when buy it is 32000, Sony is always add more to make the battery last longer )
And check for any apps that run out of battery, malware too (There are some Android malware which mine Bitcoin/Litecoin and make phone hot and run out of battery)
Also check your kernel setting or reflash ROM if nessesary.......
Mine is 1,5-2 day battery life with typical behavior.......
Well, my battery says 31440 when at 86% of charge. I haven't got many wake locks in betterbatterystats either so I'm not sure what could be the cause. I'm on stock kernel. Thanks for the heads up on that mining malware. I had no idea it went over to mobile devices. My phone actually gets a bit hot after some regular usage, but nothing out of ordinary I guess. I did lots of mods to the stock rom on my own so I'm not that keen on reflashing. I'd rather find out what could be the cause of that poor battery life and fix it by myself.
Any other suggestions and things to try?
You can reinstall your Firmware, and see if the battery life would be better. And my Wakelocks have i solved with the App DS Battery Saver.
Strangely enogh my battery was at 2880 after only 140 charge cycles.
Then by accidient it deep discharged (problems with not charging, hard reset etc. until it was fully 100% dead) and now is back at 3130 with only the first charge cycle counted as 1.
Not the case here since your's has a good number, but I wanted to add this information.
Hey guys, my Moto X used to be able to get OK battery,but since the 7.5 update, I lose 15-20% over a five hour period, which is quite disappointing. any fixes?

All of a sudden for me too, GPS is now eating up to 15% of my battery and the Android OS is at 11%... I noticed this this morning. The only thing I installed last night was Greenify...
Quite similar to what I have. Android system and Android os always on top

This is new for me. I normally have pretty crap battery life but services and OS are normally never this high. The battery on my phone is so hit or miss. It 's behavior seriously changes daily. I don't get it.

By the way, it got me to 8.30pm yesterday before I had to charge. As bad and inconsistent the battery is, at the very least I can say it gets me to dinner without too much babying. I'm just concerned when it drains much quicker than usual which means I can't use it as much for it to survive.
I've been wondering about what to expect when undervolting. There's only one kernel for this phone that I know of, the Render one; if there are more, feel free to point them out. Additionally, what kind of global offsets can I expect, and what are your settings?

Does anybody tried undervolting yet ? Is it worth to play around with lower values and save some juice or not ?

i've tryed to set lower voltage setting via kernel auditor on custom Krait kernel but, as i think, had random reboots while CPU loading growed up in short time...
Still testing on new kernel build

No undervolting but try interative governor tweaks. There is a guide how to in Nexus 5X general.
