Greetings, xDevs,
As it is stated in the title, I have noticed, that the battery is the most drained by "Phone Idle", which usually eats about 20% of all juice. Have you encountered this on you devices and how have you dealt with it?
I have LG G7, with V10k-EUR-XX ROM, Android ver 8.0.0. Always-on screen is enabled and usually I have Cellular/Data - ON, Bluetooth - ON (connected to Garmin watch), Wi-Fi & GPS - OFF. I am using Rootless Launcher instead of a stock.

I bought a Tab Pro 8.4 and decided to install Cyanogenmod 11 on it (currently on M12).
When I check my Battery usage under Settings after leaving it alone for several hours, "Android OS" is shown to be using over 60%. I tried using the Wakelock Detector app, and that didn't show any rogue apps. The "total wake time" in WD also closely matches the "keep awake" time for Android OS in Settings>Battery. There's even been a few times that my device didn't go into deep sleep at all.
Restarting the device didn't help as the problem would come back after an hour. I've tried several fixes including turning off auto-sync, using Greenify to freeze apps, and wiping my external SD card. None of them worked, but now I think I've found the source of the problem.
If I turn off wi-fi, "Android OS" no longer shows up at the top of my Battery page. Turn wi-fi back on and the problem comes back. Turning sync off doesn't change anything, so it seems like the issue is with the wi-fi itself and not with syncing apps. I even went into advanced Wi-Fi settings and changed it to 'turn off wi-fi during sleep' and still had the battery drain (though not as much - around 30% but still more than anything else). Changing the "Wi-fi Optimization" setting doesn't do anything either. I do notice sometimes when using my tablet that I don't have as many bars (on the wi-fi symbol in the status bar) as I do on my phone.
Does anyone have experience with this wi-fi issue? My GS3 doesn't do this. I assume that the problem is that my tablet device has a bad wi-fi connection and is always scanning or something, but I have no idea where to go from here.
EDIT: I might try downgrading to a previous milestone of CM11. I was reading in another thread how some other people were having wifi issues on M12 as well. My GS3 has been stuck on M10 because later updates broke stuff, so I'll try M10 on my tablet.
Hi,
to make sure I have a "clean" system, I reset my KK to factory and flashed the full 6.0 image via adb.
Now after doing my peronal settings I experience serious problem with battery drain during sleep ~2%/h related to WiFi.
I tried "keep WiFi on during sleep" at "always", "only when connected" and "never" which makes no difference.
On the battery graph I can see that WiFi is constantly on, allthough it is reported with 2% only.
Only if I switch to flight mode I can see that WiFi is off and the battery drain comes to an expected low level.
I checked with GSam Battery Monitor that there are no wakelocks and in generall it looks like MM just ignores the WiFi setting, still I can't image what uses the WiFi so extensively during sleep. On my Lenovo I have to keep the WiFi active to not get extensive battery drain and still have only 6%/day battery drain in sleep.
Anyone with similar resuts? Hints? Tips?

Hey, about 2 weeks ago I noticed weird behavior from my battery.
When phone is locked battery drain is too fast.
It seems that the "android system" keep the phone awake for long periods,
And that the "android os" keep using the cpu.
I've been trying many thing - wifi, location, sync etc but nothing helped.
Used system panel to monitor my battery life,
Here are the results from the last 8 hours (100% at morning till now)
Attached photos - Overall battery usage, Screen on, Android System, Android OS, System Panel and More detailed system processes,
In the first 3 system processes there is high cpu usage even when screen is off..
(Top one, System, attached)
I know the overall battery using seems to be good,
But it's only because I've been using the phone the whole day.
The problem is when I'm not using it - it drain very fast with no reason.
I don't remember any change I've done (didn't update the software, maybe an app),
And before that the battery life was great (and so they are now if I'm using the phone continuously without "putting it in my pocket".)
Any help?
I have a brand new lg g3 d855 successfully updated to lollipop. The reason is still unknown i was having the same problem. But then in a video at youtube i saw an app known as "qualcommn snapdragon guru" download it use its feature to stop apps and all that stuff and battery will be very improved.
Well if i look at your screenshot i could say it was normal, the one that draining your battery is your screen (based on your ss). But in other way you can download some apps to control your kernel (e.g kernel auditor) and swipe to "kernel samepage merging" tab, look if its on or off, if on just turn it off and see your battery life then, it happen to me sometimes.
Hi, got problem with battery drain with bt turned on.
I'm using miband 1s, baterry drains really fast when bt is turned on.
miband does not use bt all the time (battery works almost 30days) but it happens only on MM (checked stock 2 times, all resets done few times, after that checked fullmics 3.5 and 3.7).
here are screens.
Any ideas and questions are welcome

drive.google. com/file/d/0B4rBUUVDHHYQdXdhT2dSTDRtWGpzWFpFemNJbzI0dEthRkFn/view?usp=sharing
At those screens battery info reports Bluettoth settings, but usually it's just Android OS around 20-30% when bt is on.
Ofcourse doze does not work when bt is on, when turned off - works great.
Is there any app that checks wakelocks in MM?
Hi,
(I'm on Ressurrection Remix 5.8.5 / Nougat 7.1.2 final, rooted; installed O+3 OB24 firmware)
Recently (around mid-Feb) I started having problems with battery life on my device. I haven't changed anything (significant, not that I remember) but it was annoying me so on the road to figuring out which app/part of the system could cause the battery drain I ended up with pure Resurrection Remix rom without any Gapps (or any other apps for that matter) and... battery was still draining like crazy (which only annoyed me more). And with helpers like WakeLockDetector it say that my device was in deep sleep less then 50% of the time (and it was mostly laying on the table!)
The other day I noticed that if I disable WiFi all of the sudden device got decent sleep time (about 10-25% of awake time, which was consistent with my use case). I check the settings of wifi and had "keep wifi on during sleep" set to 'always' (however from performance and battery drain perspective having wifi on and even having idle TCP connection open shouldn't drain battery that much). I switched it to 'keep on only while charging' (no effect) and then to 'never' (also no effect).
Then I turned to old friend - 'llama' aplication and configured it to disable wifi the moment I turn off the screen and then when I turn on the screen activate wifi. With that setup I went from having 20-25% by the end of the day (unplug the phone around 6-7am, check around 6-7pm, i.e. after 12h) to still having 70% left with the same usage/timeframe. Generally this could be it, but! This is still kinda semi-automatic and I would loose notification if I don't explicitly wake device.
I was under the impression that this should be handled by doze - i.e. if the phone is lying on the table it would force device into deep sleep and then periodically wake it up to allow apps to refresh it states. In my case it looks like something is preventing doze from working correctly and placing phone into deeps sleep. I wan't as low-level as my (current) knowledge let me and I'm kinda stuck and don't know what to check next or how to fix it.
After using llama to disable wifi while screen is of the wakelock by 'PowerManagerService.WakeLocks' went down significantly as well as awake time.

I would be very thankful for all suggestions.

Is wifi/BT scanning on in Location? If so switch it off.
Also check whether the firmware you use is correct or requires updation.

I have BT off (haven't used it in my life…)
As for wifi scanning - you mean notification about available networks? yes, its' off.
What do you mean about firmware? Could that affect radios? in that case - which firmware should I install with RR 5.8.5? I'm not sure if "the latest" is alwasy the best idea (problems with compatibility)

Go to Settings>Location then click the three dot menu at top right, then click Scanning and disable wifi and BT scanning.
If that doesn't work, check on the ROM thread which firmware is recommended for your version of the ROM and flash it.
That one is also off.
As for firmware - I have (it seems) latest recommended one.
