I know this issue has been posted in forums for other devices, but I haven't seen anything about it for NC. I did try to search the NC forums but couldn't find anything that seemed to address this problem.
I am using MIUI 1.7.22. I have noticed significant battery drain due to Android OS (in battery stats), suspend (in the systempanel app), and event/o (also in systempanel). I have disabled auto-sync and any apps that appear to be likely culprits (those that might attempt to download data). This problem seems to appear with wifi on or off, and when on, I have tried both setting it to never turn off and to turn off when the screen is off. Initially I was experiencing battery drain due to cell standby, which I took care of by disabling the telephony provider, phone, and mms apks. I know many don't believe this has an effect, but I did it anyway. The cell standby drain is gone, but now I'm fighting the drain due to these other factors. Has anyone found a fix for this?
After scouting around for info, I have tried some suggestions seen elsewhere: rebooting and wiping dalvik cache. So far today I haven't had any Android OS, etc. issues. Standby life with screen off is as it should be (for now and hopefully forever)--very slow battery drain.
This is with wifi set to never shut off, which I prefer.
Suspend etc. came back last night although not as extreme as before. Hopefully some other folks will have things to add to this thread. I will continue posting progress info as I learn more about this.
From the code.google.com forums:
Confirm heavy battery drain with enabled Location & Security -> Use wireless networks / Use GPS satellites. I've disable both options and now my battery life is normal.
With enabled "Location & Security" options battery eaten by "Android OS" process (about 40-55%).
I will try this and report back.
Disabling WIFI and GPS in location/security had no effect. There appears to be a google process that prevents the system from sleeping.
I was still experiencing random battery drain due to Android OS, suspend, event/0 after switching to cm7. One suggestion I read was to disable calendar sync, as this appears to be a runaway process that attempts to connect to the server constantly without allowing the device to sleep. Doing this allowed me to get through the night with very little drain and the Android OS, etc. processes were finally behaving (within normal limits).
I'm not sure if anyone is reading this thread but I will continue to update until I figure out the solution, as I imagine this problem will become more noticeable to others who are equally frustrated with this issue.
Having same problems on my galaxy s2. Lots of people have this problem and think it's a problem with the os. What os version are you using?

Right now I'm using cm7 (2.3.5) but I was using MIUI before. Turning off calendar sync has worked well so far.
I had bad battery drain in the past and no deep sleep. but what worked for me was not to use any live wall paper. this fixed my deep sleep issues. for the battery drain, re-set your battery stats and re boot a couple of times for the stats to settle down. also check google map and latitude. in latitude just log out. un-checking sync in my yahoo email app also helped with my battery drain. my wifi is set at, off with screen. I went from 20 -30% drain in 7hrs to now 1-3% in 7hrs
I hope any of this info can help

Thank you, boxcar. I had tried all of those things (froze live wallpaper, reset battery stats, reboot, froze maps and latitude) but the only thing that worked for me was unchecking the box for calendar sync. Email sync and wifi appear to be non-issues--no difference between off or on. Evidently this google calendar sync bug is a known issue (that very few people seem to know about!). I hope google will fix this soon.
I also have same problem on my Galaxy S2. These two(events/0, suspend) drain many battery, 14% one night, without WIFI, GPS, Bluetooth.
I'll keep on tracing this issue, and share the result in this thread.

Turning off autosync seems to help the most (although setting WIFI to turn off when the screen turns off appears to help, as well). I tried using an autosync toggle but just turning it on at all seemed to result in a gradual creeping up of the Android OS, etc. problems. Manual sync of calendar and perhaps gmail and contacts seems to be the way to go. For some reason, exchange mail set to push results in no problems. The other trick I've found is to go to applications, then calendar and calendar storage, and force stop, delete cache, and THEN manual sync of calendar (reboot, recovery, wipe dalvik, fix permissions are good ideas, too). When I flash nightlies, I go through this process and the offending processes work as they should. If I don't, problems appear sooner or later.
I've had my nook on for 9 hours now, WIFI on (off with screen off) and 30 minutes of display on time. I've lost 9%, so I think I'm on the right track. This is how it should work, I.think. Of course, the results SHOULD be the same with autosync on, but manual sync for good battery life is an acceptable small tradeoff in my opinion.

Menu, settings, accounts and sync (I leave background data checked).
I found part of the root cause, maybe some old application - can work on new version, but drain many battery. Today I uninstalled the 'Android photo widget', then only 1% battery has been drained within 2 hours when standby. Not totally solved the issue, but seems OK.
I guess you can also try this, find another 'bad' application which drains your battery.
Well guys, I'm not sure if I'm the last Nook Color user to continue fighting with this super annoying headache (I know SGS2 users are, too), but I think I'm on to something. I thought calendar sync was the culprit (and perhaps it was), but the Android OS drain (featuring nemeses suspend and event/0) would not go away and the arrival of this problem continued to be (apparently) random. I had an idea that, if the calendar sync kept alternating between suspend and event/0, perhaps this was due to old events that caused the sync process to continue longer than it would normally. So, based on this idea and logic, I changed my exchange e-mail account settings to sync email from the last month rather than to sync all mail. Looking at my work e-mail history, I realized I had e-mails in various folders and sent mail from as far back as 2001! Although it's nice to be able to access all e-mail history, perhaps the polling services were constantly monitoring the activity of super old emails and folders, which caused the suspend and event/0 processes to flip out. I don't know if this is the way Android actually works but it seemed logical to me. Well, for the last 24 hours, I have intermittently checked my cpu activity through systempanel, and what do you know, when the device is not being used, suspend and event/0 work as they are supposed to and Android OS stays low in the battery % list. PLEASE let this be the fix! I know there are other factors that contribute to the acting out of these processes, but on a stripped down device with no autosync or widgets and no out of control services identified in systempanel or watchdog, there can't be many other explanations. I'm curious if others with this problem have similar settings on their email accounts. In all the forums on different sites (and I've read a ton of them), I've never seen anything like this mentioned.

Please vote there, and, may be, Google will fix it.
For those still following this thread, here's a tip. Use Gemini app manager (in the market). This has been one of the best tools I've found for managing wakelock issues and battery drain during standby. It allows you to identify apps that start up on their own (more than you think) and prevent them from starting randomly. In my experience this has been a huge cause of the standby drain problem showing up as Android OS, suspend, and event/0 in battery monitors. I'm currently sitting on 81% battery remaining with over 1 hour of screen time after 21 hours since my last charge. I know it's not a lot of usage but it's the standby time that's fantastic.

I've a Galaxy S2. Tried everything, except disable autosync. Was losing 30-40% battery at night. So far since turning off google sync I'm getting about <1% battery use an hour. Will see if it continues. Thanks.
Hi, I have an issue with the stock Android 4.2 clock app and its alarms.
I have an unrooted Nexus 4 running stock 4.2.2. The clock app usually stays in background, inactive and using 0% CPU, measured with apps such as SystemPanelLite or Usage Timelines Free. However, when setting an alarm, stopping it and exiting the app, the app stays in background but consumes between 1% and 5% cpu, when should be consuming 0%, being supposedly inactive. It doesn't prevent the phone from going into deep sleep mode, but when awake, the app wastes some battery, unless you kill it. It only uses CPU after you stop the alarm, not while waiting for it or after using the timers. After clearing the app data, the issue still exists.
Does this happen to any of you? I wonder if it is an issue with my phone ot it is a bug of the app.
Thanks.
BTW, it also happened in 4.2.1. Doesn't happen with other alarm apps.
Have you noticed significant battery drain due to this? If not don't worry about it

I haven't quantified it, but I guess it will cause a small battery drain. But it's something shouldn't happen at all, and if it happens to everyone it's a bug that should be fixed, well behaved apps don't do this.
For now I have switched to another alarm app that doesn't have this issue.
So, yesterday I noticed a sudden battery drain on my nexus 4. After checking battery it showed that AndroidOS takes over about 50% of the battery usage. It also showed that time awake was pretty much the same as the amount of time since I unplugged the phone, even though I kept my phone in sleep mode for the most of the day. After some research I downloaded better battery stats and it showed that from the moment I turn the screen off a process called suspend_backoff runs pretty much the entire time. Eventually I got it down to wifi. If I turn off wifi there are no processes running after the screen is turned off (or if there are they are 30 seconds tops), but the moment I turn wifi on suspend_backoff runs pretty much the entire time screen is off. I tried removing all of my apps, as well as doing factory reset but nothing helps. The moment I turn wifi ON this suspend_backoff consumes pretty much all the time during screen off period. Is anyone experiencing anything like this ? I have 4.2.2 on the phone and I havent' seen this extreme drain until just yesterday.
I experience the samething. Android OS would drain as much as the screen time.
I narrowed it down to the suspend_backoff. But the weird thing is that when i'm at home on my home wifi, suspend_backoff doesn't seem to drain anything at all. But when I'm at school, suspend_backoff kicks in.
Anyone help?

how did you narrow it down? Im having the same problem!
This is caused by a kernel wakelock. A bad mobile connection make battery drain worse... using WLAN nearly fixes this problem.
Thought this problem has got fixed in 4.2.2, at least battery life got improved and the wakelock reduced.
If it is appearing since yesterday, it is triggered by a app often waking the phone up using mobile data (that's why fixed with WLAN) and prevent the phone from getting into deep sleep as fast as it should.
hope i could help.
I use Greenify to hibernate every single user installed apps, then I release them one by one to see which one cause suspend backoff. But suspend backoff still occurs. So I think it's the kernel itself.

Yeah, definitely not user apps. I did full reset on the phone to factory settings, no user apps. Even tried disabling Google Play and Google store after the reset. Still the same. The only thing that gets rid of it is disabling WiFi.

Yeah, it's clear that it's the wakelock. What's not clear is why. Also it's not the msm_hsic_host that the forum link you sent refers to. I don't have a problem with msm_hsic, that one barely takes any time during the day (maybe 30 seconds during several hours of standby). The wakelock causing this particular issue is "suspend_backoff" wakelock which supposedly happens when there is a sequence of sleep/wake calls too close together so the system decides to keep it awake. I was unable to find what exactly is causing the issue, even after restoring to the factory settings I kept seeing the same problem.
Anyway, I was able to "resolve" it by installing JuiceGuard app and setting it so it disables wifi when the screen is off. wakelock is gone now and my battery usage is back to normal.
I only get the suspend backoff wake lock when I'm connected to the university Wifi. When I'm at home, everything is fine, no suspend backoff. So my guess is that the Wifi encryption at university is different and causing a succession of close "awake" and cause wake lock.
I did factory reset like 3 times and it still there.
I'll try disable Wifi on Monday and see how it goes.
Same here, when wifi disabled the wakelock doesn't occur.
I have tried almost all of the kernels and non of them seem to help.

Interesting... Maybe it is encryption. One thing with my Wifi is that it doesn't use password, but MAC list instead. It may indeed be an issue with different wifi encryption types.
OP do you have maps 6.14 on your phone? Mine kept switching on location reporting for a while and it woke my phone 344 times last night. I've been struggling with the same wake lock issues. I'm going to recharge (again) with maps disabled and see if that helps.

Check your Google account sync settings... In settings
The clowns may have left you a lovely gift there without telling you or asking any kind of permission.
The latest Maps was giving me horrible battery drain, on WiFi. I'd sleep for six hours with a fully charged phone and wake up with 10% left. it even enabled itself when. I disabled it in settings. I converted it to a user app by moving it to /data/app and greenified it. Seemed to have solved all of my issues with the suspend back off wake lock.

For some weird reason, I was also having serious battery drain suddenly since yesterday.
Turned out it was maps, and disabling Google network locations hugely increased battery life

Hello, I am the new owner of the LG G6. I noticed a fairly large consumption of the battery in this phone, especially during idle
That is why I would like for myself and others to gather in this topic all the ways to improve the G6 performance in terms of battery life, which do not require rooting and are safe for the phone.
First, disable LDB (MLT in older versions) in hidden menu (LG 24/7 tracking of phone)
Search for "LDB function LG G6" in Google, there should be a theme on Reddit about MLT with exact instructions. Maybe someone below will drop the link, because I do not have such a possibility
What else can we do in the hidden LG menu to improve the battery life?
Second, turn off bloatwear
The easiest way is to go to settings > applications and disable (uninstall) applications that you do not use. However, this way you can not get rid of all the bloatware.
What are the other methods for improving the battery life of the LG G6?
Battery standby drain on my G6 (H870DS) is also poor. I lose between 1.5-2.5% an hour when the phone is just sat on the table. I have tried many things to reduce this without success. I have AOD off, battery saver on, gmail sync off, aeroplane mode on (no mobile/cell signal at home), Bluetooth off, WiFi off when screen off. I have removed/ hidden most of the bloatware using ADB commands and experimented with apps such as greenify and forcedoze but nothing seems to make any difference to the high battery consumption when the phone is idle. I have done 2-3 factory resets and nothing has improved. Gsam battery app tells me that a lot of battery usage is caused by android os, kernel and google play services. My conclusions are that android 7.0 Nougat has poor battery idle drain. LG will only update this to 8.0 Oreo eventually which might improve battery efficiency. Some people are reporting better standby performance with their G6’s so it might have something to do with which model/regions firmware you have. I also have the latest TWN firmware and this improved idle drain slightly. I shall wait for android 8.0 Oreo then factory reset and probably be disappointed. Great phone apart from poor battery standby and not having a notification led.
The most amusing thing I've noticed is that the Always-On Display has virtually no battery consumption. Whether it is running or not, I had the same high consumption on idle.
Tomorrow morning I will check whether turning off LDB (MLT) gives something.
I am afraid of updating to Android 8.0, because reviews of other phones after the update are extremely different, some say that the battery life has deteriorated, and others that have improved slightly
I too have my doubts that android 8.0 will be bring any improvement to battery standby drain so will be waiting to see other people’s experiences before I update.
This is also fun, because for the same type of device people report different effects of upgrades. So usually Android upgrade is a high risk game
It seems that turning off the LDB (MLT) feature has reduced the battery consumption in idle 2x, now the phone uses about 0.25% per hour.
Very interesting, that's the first time I've actually heard or read something about MLT/LDB. I wonder what both stands for and also what's its literal function. Polish forums are flooded with threads about "LG's spying app!".
I gave it a try and turned it off. Also I've turned off logging services too. After rebooting, I've removed two apps that are mentioned here and had to force-reboot again as "MLT has stopped" started popping up after a minute or two and it prevented me from doing anything on the phone
Hopefully it will improve battery life... even slightly, but improvement is improvement. For me, battery life is the weakest point of this phone (damned Android 7.0 and its idle battery drain bug)...
RAM is not so important for me, 4 gigs are enough and I've never experienced any slowdowns even with 30 tabs opened in Chrome
Someone on Reddit suggested disabling background running services for apps that use it for no real reason. This can be done by following:
Device settings > Smart doctor > Tap Memory > Tap overflow menu > Tap conserve memory
Selecting the apps that you want to not run in the background and setting the toggle to ON will help. Maybe. Ish.

Manually turning MLT off should be enough, I removed these apps just in case but I don't think it makes MLT "double off" as it's already killed in service menu.
I will do some checks and report in few days, stay tuned.

I don't have my phone with me but as far as I remember the steps are almost exactly the same as for MLT/LDB disable.
Only you click the button about logging instead of MLT, one or two rows below. Then you have to tap "disable" button until every logging service below is set to "Disabled".

This option is called Log Services above the LDB function in the hidden menu. Unfortunately all these services I have already disabled :/
Another hint. Make sure that the built-in flash does not light when receiving calls and messages. You may not notice it, because the phone is always on the back.
This can be turned off: Settings> Accessibility> listening> Alarming flash
Tomorrow I will check how much battery I saved
My idle drain was over 60mAh per hour and over a day this was more than used by the screen. The Greenify aggressive doze helps, as does restricting mobile data in the background plus disabling all the bloat. Adding in the LDB hack has reduced idle drain to less than 40mAh per hour, not perfect but much better. To me it looks like LG thought the larger battery meant they could turn on all their rubbish and we wouldn't notice...
Going back to the subject, disabling the flash, acting as the notification light, did not bring about much improvement in battery life.

Thanks for the link. Some interesting information was in this video. The most interesting, because I've never seen it before, was to turn off Bluetooth scanning, which works even when Bluetooth is turned off.
To do this, go to settings> location> three dots> scanning> Bluetooth scanning
It seems that there are no hard and fast rules about this. Without any modification whatsoever on my G6, idle goes about 1% every 2 hours or so, even with light use. I'm running the v11d update of Oct 21. The update improved battery life that was already good. At the end of a workday, with bluetooth active and light to moderate use and a trip with Waze I typically have 75% left. It may be a regional issue with firmwares running slightly different apps in the background depending on where you are, or maybe difference in cell tower distances-- with a weak signal the phone radio powers up higher. Maybe LDB isn't used in my region (Middle East/Israel)
Are people using apps such as greenify, force doze, hibernation manager or clean master and if so what benefits in standby drain are they experiencing? Are these apps any good and do they create any problems of their own? From personal experience removing QuickMemo using adb commands improved my battery standby drain a little. What changes should be made in developer options to improve battery life such as animations or limit background processes etc. Nougat is set up to manage battery life in a certain way, so I just want to make sure I don’t make any changes or install any 3rd party apps that make my battery life even worse. What I have come to realise is that the G6 and the snapdragon 821 are not set up for efficient battery standby. Previously, I had a vodaphone smart ultra 6 (rebadge zte blade) with a 3000mah battery on marshmallow that would last upto 4 days on a single charge!
I just can't seem to get there. I'm on stock, latest, unlocked, not rooted. I can go to battery|battery optimization and turn off battery optimization for apps but Bluetooth isn't listed. I can go to apps, show system apps, see Bluetooth, it shows battery is being optimized, if I click to change it takes me to list of apps like above where I could do it but Bluetooth isn't listed.
It's kind of important, I'm a diabetic and wear a glucose sensor but the phone loses touch with the sensor too often. I have to carry my old phone just for that at the moment...
Thanks!

This workaround may help.
I experience the same with my OnePlus 7. I think I deactivated all battery saving options for xdrip+ and even disabled the "sleep standby activation" in the androids battery > battery optimization > advanced optimization settings. But still one hour after falling asleep my device doesn't get any more readings until I wake the screen. Could you find a solution? Perhaps we have to flash a custom ROM to get rid of some unadjustable system settings?
I will try the workaround from Glaux. Needs another night.

Advanced battery optimisation
Hi
There is an advanced menu accessed from the battery optimisation page, the one with all the apps.
You need to click the 3dots and select it. It seems directly related to bluetooth and the other radios sleeping.
