Are you having high battery drain with XXJVK firmware, or any other 2.2.1 firmware?
Does your Battery Use shows high CPU usage time on Android OS?
Then, check if you ever had Software Updates logged in! I noticed high battery usage once I logged in for OTA updates. Possibly, the device is retrying the connection to update server (which will always return timeout). You can see the Software Update service running all the time once you logged in.
If you have logged in Software Updates, go Settings->Applications->Manage Application->All->Software Update->Clear Data
Once you have logged out from Software Updates, the service disappears and personally, battery life doubled.
Thanks, i will try it!
It really could be the last chance to solve my idle-drain-prob.
i'll report back.
//edit: cleared data, service automatically stopped. i'll report back tomorrow if it solves my drain-thing.
Yup i had it running too since boot.. cleared data and will report back
Let's hope this is the answer. I've just took the drastic measure of doing a hard reset and now battery drain is pretty much zero and phone is idle when screen is off. I'll keep installing and enabling things and see what takes more battery.
Very interesting, I did check if there were any updates, and I suffered from random battery drain. At first I suspected Google Maps/Navigation, but you could be right. I started Maps, and Navigation, killed en cleared OTA, and I am monitoring the battery.
I have found that when i use the built in task manager to "clear memory" as soon as i have done that the battery drains alot faster and my android OS in battery stats goes through the roof (from 5% to something like 14%). It has been running fine since yesterday and i cleared memory only to find my battery went very quickly from 28% to 9%. I rebooted the device and all is well, i wont be using that option anymore
After installing jvk full I installed jve modem, rooted and did battery stats wipe and battery issues went away.
i lost 25% over night in airplane mode
background & sync = off.
after clearing dalvik cache & battery recalibration using battery calibrator from market i have 5-7% drain per night, and 30-40% per day... last battery time was 2d 19h 14m, with some calls, some games, some wi-fi and some hsdpa & with weather widget update every hour.
info
i9000 + JVK (repartition 512, with bootloader) + CF Root
P.S before clearing dalvik cache & battery recalibration with same use i have maximum battery life - 23h
Clear the data for "Samsung Account".

There's something very wrong with your phone, either your battery's shot or there's a rogue program draining it, you shouldn't lose more than 1-2% overnight in airplane mode.
Same problem here. I hate this device...
Is it just me that think battery life is much better than on froyo?

I have no battery drain since i upgraded to jvk.

I'm seeing huge battery drain like others, sometimes more that 50% in a few hours doing absolutely nothing, wifi & 3G off and OS takes up to 60% of the battery usage. I never activated Automatice Updates since I flashed JVK. I am now on Darky's v10RC3. Only a few people are having such problems, most users say they are experiencing their best battery life ever.
I noticed that this drain always happened to me after I used Maps / Navigation. So I suspect them to create problems, maybe kicking off Software Update in a bad way. And rebooting stops the drain (it once took as long as a full flash for my phone to reboot...?).
So I have bought for $1 this nice app called Autostarts that shows which apps autostart, what triggers them to start and it is then possible to disable by app / event.
When I tap on Software Update, I can see that it kicks in on these occasions:
- After Startup
- Application installed
- Application removed
- SMS received
- Secret code entered
I disabled everything as well as for Map, so now it's no longer showing in running apps / processes.
Will follow this thread !

Spot on.
My Android OS battery usage is down to 3-5%.
Great find guys, Thanks a lot!
Also, a little suggestion here but I need someone to confirm.
Regarding Google Maps, I was having some trouble getting rid of Hotpot and Rate Places processes as they were constantly running for no reason and restart after I kill them. Another 13% drain. So yesterday I updated to Maps 5.3 and the processes are no longer there even though I've used Maps, Hotpot and Places
I upgraded with odin, repartition and bootloaders. Since now the battery life is very good, i can see the difference by eyes.

I'm experiencing a lot of wakelocks on 6.0.1
It's mostly happlens when I disable WiFi and and leave the phone over the night.
The problem is gone only after a restart, and will ocure again if I disable WiFi.
Anyone with similar problem and most importantly - solution ?
How can I find what cause this wakelocks?
(I'm not rooted)
if you are not rooted then how did you find that your device is suffering from wakelocks ?
use gsam battery app to monitor wakelocks.

On the battery page, when I click on graph it shows the detailed graph when the screen was on, when wifi was on, etc. When I noticed fast battery drain I can see that the "awake" graph is continious meaning that device stays awake all the time, even all apps was closed and wifi, and data was disabled.

Reset moto display (clear data and cache) and use the new battery optimization on all your apps. And for extra, use greenify which can also show you the apps that are running in the background and is able to aggressive doze your device.
Could also be an app that screams for an internet connection since it only happens when you disable WiFi.

boot into safe mode, leave the phone for a few hours and see if the wakelocks are still there. if not then it is caused by some apps.

Its part of the moto app. Go to settings>app>moto>storage and clear data and cache. Mine was also giving a lot of wakelocks first few days when it was new, because of moto display had a bug waking up the device every few minutes. I did a factory reset and everything was solved.

it happens mostly when I turn off wifi
any suggestions?
I'm unrooted, just stock 6.0.1 nothing hacked or whatsoever.
Reading this thread it's not actually drians your battery, but it's a bug in the battery statistics showing your wifi was on. Read this thread for more info.

This problem started a few days ago randomly. I never installed a new app or changed any settings. Started out while I was on a custom ROM. I tried another ROM and same thing. Tried fully erasing everything my phone and still no luck. Fully unrooted and went back to complete stock and Android system is still eating away. When I went back to stock I started the phone as new. Did not restore any apps. This is very frustrating cause it started out of nowhere and it doesn't want to go away no matter what I do. My phone is dying halfway through my day with Android system having double the % that my screen on time has

Go into settings/accounts and see if anything is having a problem syncing. You should also turn off Bluetooth and set location to battery saving if you aren't using Bluetooth devices or GPS. Which build of Android are you using? Is the high battery drain when the phone is idle? In use? Both? Presumably you wiped the system cache after going back to stock?

Accounts are all synced good. I have wifi and Bluetooth scanning off. Location is on battery saving. And I'm on latest vendor 7.1.1 and usually it's when I'm using the phone. Idle drains some too but not that much of a difference.

Did you wipe the system cache? The only obvious thing that might drain your phone when in use is having the screen brightness set very high, but that shouldn't make a huge difference. You said the problem began when you were on a custom ROM but now you are fully stock? That's odd. Poor network connection can also cause high battery drain. I think if you reset your network settings it will force your phone to look for the closest available cell tower. Do you have GSM or CDMA service?

When battery is run down, what is displayed under battery>>android system>>use details? Please paste those details here. Are you in an area of extremely poor LTE signal? Have you ever used Better Battery Stats? Install it and run it for a full battery cycle. Your problem will likely be solved by a factory reset from the stock recovery.

Wouldn't high screen brightness go under the screen category and not Android system? I will reset my network settings and see if it makes a difference. I would assume flashing back to stop and erasing all data on the phone would do that and wipe all system cache as well.

I have BBS installed but without root I don't think it's much help? I will post screenshots when my battery goes down to about 15%
Some people have reported that the following works, although I don't understand why it would. Go into settings/battery/battery optimization/all apps/reset app preferences.
A factory reset shouldn't be necessary if you did a completely clean stock install but it also couldn't hurt.

I never use root even with custom Roms. I feel like I have no need for it. I did what was mentioned earlier and reset my network settings and also I disabled chrome and started using a different browser and so far Android system is the same percentage as screen. Not good but way better than before. BSS is also showing 2 hours "awake (screen off)" which is kinda alarming

You didn't see anything odd when you went into accounts and looked at syncing? For Google you clicked on the account and looked at each individual thing that gets synced under Google? If you were rooted you could try the Naptime app. I hated it but it has many fans. Basically it puts your phone in an extreme Doze state when you aren't using it, which might fix your problem. But if you want anything to work with the screen off you have to exempt it from Doze. Screen off in Naptime kills pretty much everything.
Same here. Everything stock. Just checked accounts settings and everything is good.
right now my top 5 is:
Screen 13% (2h:52min SOT)
Android System 10%
Android OS 9%
Facebook 8%
WhatsApp 5%
and in overall I've been around 40 min on Facebook, and you know that this **** consumes a lot, so go figure out how the hell is Android System and OS above it.

They are components shared by applications so that's rather normal to have them high.
I don't care about Android architecture much so only look at my SOT (which is nominal).
Those interested in why system and OS are high, should read the battery stats source code to see what's grouped under these and how it's being calculated.
I locked my bootloader last night and did a factory reset from settings. Right now Android system is at 5% and screen at 4%

Android System tally is the sum total of a number of components. That it is "high" is not necessarily a big deal. The real question is: what are each of those components using? When your battery is run down, what is displayed under battery>>android system>>use details? Those usage details may help you find a problem if you even have one. Short of rooting and running a dedicated battery usage/wakelock app, these details may be the best you will get.
Decided to run purenexus and exkernel with root to get better stats. Battery is a little better but still not even close to how it used to be. Here are screenshots of everything . Woke up with 100% around 5:30 am. Went to work and the gym and wat he'd some YouTube.
The only way I found to fix this issue was to implement aggressive doze as soon as screen is off.
If you're on MM this can be done using apps like ForceDoze
And on Nougat using NapTime
Furthermore , I also implemented ElementalX kernel with Hawktail governor.
Since these changes my Screen is on top of the list in battery and maximizes my screen on time. Nothing else works for me.
The phone tends to stay awake needlessly without all these tweaks.

I really don't see anything wrong here, except awake time and maybe SOT. 4 hours SOT is very good for stock and you are at what 3.3 hours? I use the Hawk Tail governor profile in EX as well and it gives me just a small amount of improvement over stock settings. I use the stock rom, rooted with EX and get 4-5 hours SOT.

I think the 2 hours awake screen off is normal unless you use an App like Naptime to put your phone in Doze as soon as the screen is off. If you are really concerned with idle battery life you might want to try Naptime, but you may need to play with the settings so the phone works like you want, Naptime by default turns off everything that isn't excluded from Doze when the screen goes off. That includes music players and the fingerprint sensor.

My battery usage is around 9.6% an hour. Built in battery monitor must have been altered by my deleting spree. I also got rid of the phone manager too. I've been on battery for 35 minutes and have lost 6% battery. Thinking about going back to stock and taking a different approach as somewhere along the lines I mutated the Android system (using most of the battery).
Please specify what radios you have on during usage and screen brightness and screen on time is a big factor. I didn't go crazy and delete stuff other than AT&T bloatware and apps I don't use, and I'm quite happy. Maybe good idea to go back to stock after making a TWRP backup and do debloat in phases with days in between .
Did you try suggested battery app?
Yes I'm using gsam and now I'm up to ~13% usage an hour. BT is always off. Wi-Fi is always connected. Screen is always at auto so it's pretty dark. I'm going to go back to stock so I can figure out what exactly is draining battery.
Gsam should tell you in apps list. Did it prompt you for permissions to grant via adb pm grant?

It didn't, it asked for root at one point. Android system was chugging it all down. So it must have been a system app or service I either deleted or disabled. I'm back on stock now and we shall see.
I always notice phone lost more battery after rooted. Also removing wrong app can caused it too. When the system look for that app and it's not there. It keeps looking and cause the phone always ON (even screen off).
Going back to stock is one way to fix because you are not sure which app you removed wrong after rooted
That gives me an idea. I would do an "adb shell logcat" and see if it's spewing errors/FATALS if you suspect battery issues. I've seen this when something can't be found by system at startup.
How can I get back to stock?
Flash your TWRP back you made following the root/TWRP instructions . Should work, but don't restore the stock recovery unless you want that. Restore boot, system, and maybe data. Wipe cache and dalvik from TWRP before rebooting. Good luck .

While you are looking for a stock TWRP back, go into TWRP and wipe cache and dalvik, then reboot. Phone will sit on AT&T logo for about 30 minutes. Maybe it will fix the battery drain problem. Before you do that, do a logcat and see if it's spewing fatals or if you see any hints.

Use better battery stats app to see what your wakelock is.
GSam Battery Monitor can also tell you about wakelocks. I'm not sure if it breaks it out by app or not. Are you using free or pay BBS?

Ive always found the the OEMs on die power management better than placebo apps. Hardware based will out do software anyday of the week. My own opinion only.

Hello,
First off, I recently noticed my battery drains fast and I have read countless threads on the device idle. I will be unable to make it to 4 or 5 pm at work without plugging it in to charge a bit before I leave.
In settings, screen is at the top, followed by Android System, Device Idle, Android OS, Cell Standby.
I have cleared the phone's cache, i have cleared google play store and google play services caches. I have uninstalled any possible rogue apps. Not sure if the phone signal is bad causing the drain, but then why does it happen overnight in my apartment on wifi?
What should I do next? Is my wifi at night untelated to the phone signal? I wake up to about 13-15% on average. I have gsam from a while ago, should I take a screenshot of something.
I don't know if is there a definitive guide to battery drain. But there in XDA have some threads that can help you:
