[Q] Mi2S High Idle Drain (wakelock?) - General Questions and Answers

I have a Mi2S and I'm running the latest stock ROM 4.4.23.
Ever since the 4.4.11 update I've had poor idle battery life.
Before that when I look at my battery usage, as long as I have good signal and the screen is off, the battery level graph is flat.
Now, almost always when my phone is idle, no matter what there is some heavy drain, it was approximately 25% over 12 hours.
I've tried all the MI2S updates since then and they are all having this issue. I have not installed any new apps or changed anything on my current ones.
Attached are some wakelock detector screenshots.
Sometimes 小米服務 has many wake alerts, but sometimes it does not. Weather app is disabled, and autosync is disabled too. Occasionally 小米服務 does not have many wake alerts but that doesn't seem to reduce idle power draw, and I think it had this many wakes before as well.
Also the 3h wakelock app is the music player; the idle drain happened when the music player was off.
Thanks for reading.

Bump...

So I spent a night in airplane mode, and voila! 3% drain over about 12 hours!
I'm still trying to figure out exactly what it is, but whenever I get the chance to I'm going to spend another night in airplane mode with wifi on.

There is a nice little utility app called power tutor, which shows you exactly which app drains your device. Maybe the problem isn't rom related...
You can find it on the play store.

[Q] Battery draining and high CPU load when idle

Hi everyone here
I got a concern about my TF101 Tablet.
When I switch my Tablet screen off and set the WiFi as turn off when screen off, my battery still drains extremely fast. From the pic you can see, my battery is running out from full to 10% in only 1day and 6 hours without any use. My GPS and bluetooth are also turned off in this period. From the pic you can also see my CPU load is over 30% at most of the time.
From the second pic, I can see the process "System" uses the CPU very hard
Can some one figure it out and I will appriciate it very much!
Here I have to bump...

I am seeing the exact same problem, not sure what the cause is either. I read somewhere about "wakelocks" where some app will try to keep the CPU awake when you try to go into standby and it results in high system usage.
Thank you for this thread, I am also having this problem. I think the problem for me may be because of Google Maps.
Basically, I'm running some tests now. I had massive battery drain overnight while I slept. The tablet would go from 90% down to 50% in an 10 hour period (4%/hr). It didn't matter if it was docked or not docked. I was running Google Maps v5.8.0 and saw some people post that the new version is eating up the battery. So I removed the updates for Google Maps and tried again.
Now I'm running v5.6.1 of Google Maps and the battery went from 100% to 42% in a 17 hour period with absolutely no use (3.5%/hr). I checked battery usage, and Google Maps is at the top and it's taking up 41% of what was used. That's ridiculous.
So now I'm going to install the latest Google Maps and see if this helps at all. I've also attached some screen shots of my latest tests.
Other details:
Wi-Fi is set to sleep when the screen turns off.
MobileDock Battery saving mode is checked.
Use location for Google Search is unchecked.
I did another test last night after having updated Google Maps to v5.9.0 (latest). I got the same results. Google Maps is eating through my battery when the tablet should be sleeping.
Here's the results:
The tablet was undocked, and fully charged.
I didn't touch the tablet for 15 hours.
The battery went from 100% to 55% in 15 hours = 3%/hr drain.
Google Maps was largest user of battery at 75%!!
I also did a reboot after I updated Google Maps to v5.9.0.
WTH is going on here?! Anyone have any ideas??

Try turning off all location services (WIFI/GPS) and see if the problem goes away. I did something similar and the sleep mode CPU utilization dropped back to 1% or so. I haven't yet enabled the settings one by one to see which one cis causing the issue.

You are correct. I am able to turn the Airplane mode on and see virtually no battery drain at night. But this is rather annoying to have to turn on airplane mode every time you are done using the tablet and turn it back off whenever you want to use the tablet.
The best option would be to locate the source of this issue and fix that. Tonight I'll be testing Google Latitude turned off to see if this fixes anything.
As a test I turned back on location services (GPS/Google) but unchecked the use WiFi for location and found the problem went away overnight. Only a few % CPU use. Not quite as good as leaving in Airplane mode but close. Lost about 2-3% CPU over 7 hours. WiFi use setting is to disable with screen turned off.
So after my test last night, I still had massive battery drain.
I turned off Latitude as best I could last night and still same result. Google Maps is chewing up my battery like no other: from 100% to 52% in 15 hours with zero usage by me. Anyone have any other ideas? Any other apps that might be causing this?

I had previously logged out of latitude and saw the same high drain result as you, so don't think it is that. When I disabled the WiFi location the drain stopped (leaving gps on). I agree it may be Google maps related since it uses the WiFi location services (since maps uses that service to locate the tablet along with gps).
I have a similar issue, but my problem is not with Google Maps. Instead, the main battery drain is "Android System." I usually leave my Transformer on standby 24/7 and used to only have to charge once a week. This problem appeared out of the blue a few days ago.
Google mail is the only thing on auto-sync, and this setting has never caused any issues in the past. Thus, I'm not sure why Android System is now suddenly waking up at random when asleep. You can see in the plot that System constantly requires 30% CPU usage once it happens, until I actually turn the device back on.
In addition, my wi-fi sleep policy is set to turn off when the screen is off. Recently, it seems it is always on, even when the device is asleep.
EDIT: The graphs from the OP suggest that our issue might be related, but the problem appears to manifest much more frequently for the OP. Crossing my fingers that next week's update somehow fixes this problem.

The system process was the same issue on my system as well (didn't show up as google maps). I confirmed that turning off the "Use Wireless Networks" under Location and Security stopped the constant 30% cpu usage when in standby.
After freezing Maps, which is the biggest culprit for me....i noticed, System Process' was way high now.
28%
After doing some searching.... came up with this
http://forum.xda-developers.com/showpost.php?p=16828183&postcount=605
At least for my case.
Google Maps battery drain Solved!
For me, I figured out the issue was Latitude.
I was getting bad battery drain overnight and Google Maps was the largest user by far. I finally signed out of Latitude completely. Battery drain dropped to around 2% (total) overnight! This is acceptable!
As it turns out, Latitude wakes up my device while it should be sleeping in order to update my location and therefore draining massive battery overnight. I'm going to post this as a bug with Latitude/Google Maps because this is causing waaaay too much battery drain.
So it looks like I won't be able to leave Latitude signed in. Once I'm done using it, I will have to sign out of Latitude. This way I can leave Wi-Fi on and set to turn off when the screen turns off. Thereby I get really good battery life again.
On a side note, my phone has the same behaviour, but I never noticed it because I'm usually charging my phone at night. So Latitude...basically...sucks (battery).

Suddenly getting crazy battery drain

Anyone else get stupid fast drain while its sleeping? I have wifi sleep policy set to turn off wifi when screen is off, and using the task manager nothing looks to be running that i havent launched myself. But usually i'd have the battery last DAYS and DAYS if i wasn't using it that much, but the last few charge cycles it's been nearly dead at the end of the day. Is there an app I can get to monitor stuff while its sleeping to see if something is keeping it from deep sleep? I can't remember what i've installed recently that could keep it in wake-lock or whatever. Thanks guys.
There's a build in feature in the settings menu to tell you what uses battery
Check that the wifi is actually sleeping when the screen is off. Tap the power button to wake up the tablet then look at the notification bar in the right hand corner to see if the wifi is turning on and connecting. If its not doing that then I dont think the wifi is disconnecting and turning off when the screen is turned off.
For battery issues, two "must have" tools are "better battery stats" and "cpu spy"
gary's right. download better battery stats here:
https://market.android.com/details?id=com.asksven.betterbatterystats
and since the developer of that app loves XDA, there's a free version for us!

Try loading the free util Auto Airplane Mode which has helped fix the SOD issue and the related battery drain during the SOD.
Sorry to push the old post up again.
Recently im suffering from the weird battery drain, i didnt play/use my phone much on sunday , the idle battery drain is huge. like 8 hrs from 100%-40%.
I've installed both betterbatterystats and cpu spy already.
From battstats , it shows that kworker/0:1-3 and kworker/u:12-13 etc using up most of the batt , secondly is the doubletwist music player.
From cpu spy, most of the time is with 200mhz even i didnt use the phone at all, rarely goes to deep sleep mode.
for the process kworker it didnt show whats the process/app is about , anyone else know wt to do now ?
Same problem here :-(
Fully loaded at 7 o'clock and now I'm 34% - this really sucks!

All you can do is to check the apps you recently installed or updated. They might lock you from sleep. No easy way to control this
For me it was the "samsung-keyboard" - I froze it and now everything seems normal.

[Q] About Battery Life

Hi,
I have a question regarding battery life of the OPO. I'm still not sure whether I have a defective battery, or some apps drains my battery like crazy (or both?). I hope you can help me with this.
In the first 2 weeks since I got it, I use my OPO for mid to heavy activities (a lot of Whatsapp, Youtube, streaming music, etc). I always start the day with 100% battery and I thought it was normal to see the battery drops to at least 20% at the end of the day. To be honest, I didn't check the battery stats in Settings even once in this time frame, and due to my heavy usage, once again I thought this was normal.
Until one night I decided to plug the charger earlier than usual, unplug it around 11pm (w/ 100% battery), then I fell asleep. I was shocked the next morning (8am) when I saw the battery has decreased to 65% with no activities whatsoever. I check the battery usage in Settings and then saw Google Play Services (GPservice) at the top of the list with 45% usage, with "keep awake" time almost identical to total time on battery. I did some research and found some advice including 1) denying GPservice abilities to "keep awake" and "wake up" via privacy guard (from this thread http://forum.xda-developers.com/oneplus-one/general/guide-google-play-services-battery-t2832525), 2) turn off location, 3) turn off sync, but none of them seems the solution to my problem. Since then, I always check the battery usage and reset it, to see if GPservice still at the top. Sadly it still there. After I reset the stats, go to sleep directly and check it about 1 hour later, GPservice uses 40% - 60% of the battery usage, draining about 6% battery / hour.
With screen on a few minutes, it easily drops to 5th or 6th place with ~7% usage, with screen and main apps I use on the 1st and 2nd place. When I googled about this using Firefox, that's when I start worrying about something else, the battery itself. With wi-fi and low brightness (less than >20% if I convert it from the slide bar), browsing with Firefox decrease the battery 1% in 2-3 minutes, no or low usage drains 1% in about 5-6 minutes. In contrast, charging increase the battery 1% in 1 minute. Is that normal? IDK, usually bad battery increasing faster when charging and decrease significantly when in use.
Please help, especially about the excessive GPservice battery usage. And if it's possible, I prefer non-root solution for it. Thanks and sorry for my bad English.

Definitely sounds like somethings not right, what apps do you have that access or could potentially access your location? If you're still not having any luck, as a last resort you could try a fresh install of CM11S and install your apps one by one to see if you can determine if any are responsible for sucking battery.
Give the below app a try:

Maps, Google Fit, Google Now, among other things.
CMIIW but I read somewhere that GServicefix does the same like privacy guard, denying some service to keep awake, wake up, etc.
So I installed Gsam and run it about 1 hour. Interestingly in there, Kernel (Android OS) is on the top the % list with 60% usage (mostly phone in idle/sleep). When I switch sorting to Kernel Wakelocks, it shows event0-798 & event2-798 as the top 2 wakelocks with around 7000 wakelocks. I'll update in few hours, thanks.

Hi, sorry for the late reply.
It seems reboot the phone a few times solves the problem. Battery usage now seems normal when idle, even with location & sync turned on.

Terrible stand-by time

I have a serious problem with stand-by time of my galaxy s7.
I have updated my device to Nougat and i am using ForceDoze to put the phone to sleep (without root, with adb command), although i am not sure if it is really working.
I lose about 3-4% battery every hour when idle.
With idle i mean always on display on, wifi or data on, gps and bluetooth off, power saving off.
When i check better battery stats and accubattery, it shows the phone in deep sleep most of the time.
I think this amount is ridiculous. It shouldn't consume more than 2% with this setup, assuming AOD consumes 1% per hour.
I don't have a problem with screen-on time. Only with stand-by time.
Do you have any suggestions for me? What could be the problem?
Find out what is running on your phone by going to running services. Disable the apps you dont need running, turn off always on display and see your battery times then. Clearly something is running in the background and this is up to you to find out what is running....
Second option root your phone, uninstall the bloat and install greenify.

Hi mate
Most of times is configuration issues or a rouge app , install a an like BBS let it run for a few hours and check the log to see who is keeping the phone awake.
review your settings wifi , location email, FB ........
I think i found what the problem is. It is always-on display. Last night, i turned it off. With only wi-fi on, i lost 1% per hour.
Apparently, AOD consumes way more juice than i thought.

I found AOD prevented Doze from working, which in turn used way more in idle, so it's not specifically AOD draining it, it's because it's not at it's lowest power state during idle

Stop wifi drain on standbyI

I just got an LG V20 which is good on battery when in use but sucks when not in use. The culprit is always wifi. I just discovered the root cause is Location services that is using wifi to get locations even when wifi is off.
To stop this, go to settings->location->scanning.
Uncheck wifi scanning. For good measure, uncheck bluetooth scanning.
Go to wifi menu ->advanced-> keep wifi on when screen is off
Change to never or "only when plugged in"
Hi,
thanks for your helpful tips..
So out of the 3 tips you have:
1. Uncheck wifi scanning
2. Uncheck bluetooth scanning
3. Turn wifi off when screen is off
Any idea how much does each option save (if you've quantified)?
I'm happy to follow points 1 and 2. I'd only do 3 if it really helps a lot, because most apps would use data if wifi isn't available to periodically phone home.
I have always been dissappointed with my V20 standby time.. I had all of these settings on.. so i'll see how she does now they are off.
Thanks!
My standby time is from 0-4% over 8-9hrs. I really cant complain.... but the phone is facing down.
I wasn't aware of the wifi location scanning, and the bluetooth scanning. Giving it a try as my standby time has been horrible lately.
I am also facing severe battery drain on my LG V20. Battery easily drains by 5-10% per hour even when the phone is lying idle with screen off. Major culprits are 'Phone Idle', 'Android System' and 'Android OS'.

Try what is mentioned here
Post your screen shots here and tag or quote this post
As a side note, I've found that using wifi and cell data to help location services causes maps to scan these options and slow down (maps keeps saying every 5 to 15 seconds "searching"). By using gps only, the maps app is faster and less battery drain.
Obviously if you are indoors you need the help of wifi or cell data. But in the car or outside it is unnessary.
Thanks for your tips it's very good for my life battery. :good:

- see the cpu running, userspace wakelock & screen on lines. They seem to match. Screen is on, cpu working with userspace wakelock. Close to 7pm the screen is off but the cpu is running, because you were listening to audio. I don't see a problem here. Looks normal
- you screen off discharge rate is 2.56%/h which seems a bit high. If you were streaming audio this might add to it. Do you have the second screen on when the main screen is off ?
- somewhere around 12pm you are using data for about an hour. Mobile Signal strength isn't very good, mostly yellow. What i don't understand is why your wifi is also on ? and this is in an area where wifi signal is bad. Both of these will add to drain. And in two hours your battery dropped from 70 to 40
- little after 1pm you're on wifi for a couple of hours but the signal is weak
- around 5pm you're back on data streaming audio and battery takes a nose dive here. Down 30% in like an hour. Were you moving ?
- then you charge up to 85%, doze kicks in which is good, if there was app drain doze would not come on, for the next 5h without use, you lose about 5%
- the part i don't understand is between 1am & 6am, battery drops 10% yet full doze (blue) is on. So there is some activity going on there. What ? sync ? updates ?
Not sure about the aggregated stats as you've recharged up and run down fr a second cycle so it could be your off screen drain is twice as high because of that
charge up again, go through your day and save log when you're at 5% and lets see the two screenshots from just one charge cycle

- see the cpu running, userspace wakelock & screen on lines. They seem to match. Screen is on, cpu working with userspace wakelock. Close to 7pm the screen is off but the cpu is running, because you were listening to audio. I don't see a problem here. Looks normal
- you screen off discharge rate is 2.56%/h which seems a bit high. If you were streaming audio this might add to it. Do you have the second screen on when the main screen is off ?
- somewhere around 12pm you are using data for about an hour. Mobile Signal strength isn't very good, mostly yellow. What i don't understand is why your wifi is also on ? and this is in an area where wifi signal is bad. Both of these will add to drain. And in two hours your battery dropped from 70 to 40
- little after 1pm you're on wifi for a couple of hours but the signal is weak
- around 5pm you're back on data streaming audio and battery takes a nose dive here. Down 30% in like an hour. Were you moving ?
- then you charge up to 85%, doze kicks in which is good, if there was app drain doze would not come on, for the next 5h without use, you lose about 5%

Thanks a lot! Please find my answers in sequence.
- I listen to music while going to work. But, that is, till 8:30 AM only. Yes, I have 2nd screen ON when the Main display is OFF.
- I watch stored videos during lunch (12-1pm) for around an hour but it shouldn't be using data as I am playing stored videos.
- Around 5 pm, I leave for home. Again while going home I listen to music for half an hour.
- I have no Idea of what is happening during Night because I just leave it and don't use it until morning. In fact, I have scheduled the 2nd screen to be off between 11 pm and 6 am
I will try to run a proper cycle as you have suggested and will recapture the logs.
I understand the battery dropping while I am using the phone (listening to music/watching videos/browsing/anything else). What I don't get is the battery dropping insanely when I am not using it. For example, once I reach the office, I stop the music, kill the music player and just keep the phone aside. After 1-2 hours, as I check my phone I find battery dropped by 10% or so! It's the battery drain while my phone is just lying idle that is troubling.
Also, I have noticed that once I charge my phone and then leave it (Not using it) the battery drain is minimal like 1% per hour. But, once I run some app (music/browsing etc) for a little while and then leave the phone, the idle battery drain is pretty high.

- When you have the second screen on, is the phone facing up or down. What i notice with that second screen is it ignores any brightness settings. If the phone is face up and pointed at a light, the second screen becomes very bright. If its facing away from the light then it dims. Depending on how your phone faces you will either have more or less drain here, without doing anything and phone just sitting there. Typical overhead with second screen on and normal brightness ie not too bright is around 1% per hour. This could be adding to your off screen drain. Why not try a couple of cycles. One with second screen off and another with second screen on. Just to see how your off screen drain rate is like.
You say you listen to music only upto 8:30AM, take a look at the audio line. Can you see audio triggering ? there's little blips there after 8:30AM which continues till 5:30PM where its solid. This is your ride back where you listen for an hour. The 5:30 audio is ok but the blips in between are not leaving aside lunch video. Each time there is an audio blip there is a wakelock. Pay attention to the duration of the audio blip, if its a few seconds it could just be notification, but if its longer, does it correspond to your use.
Now look at the top app line, try to find which apps are running when audio triggers. To do that hover over the top app line which coincides with audio when you were not listening to audio. You will see a popup screen with a list of apps. Or check History Stats - TopApplicationSummary for a table, screen shot that and post
Do you use a lot of widgets that update in the background ?
- something was using mobile data when you were watching stored videos at lunch. Take a look at the'mobile radio active' line and you see activity there around lunch. Your wifi however is off and not running. If there were any apps running they were using mobile data, this is extra drain
- take a look at the line that says 'foreground process'. it's pretty solid right through both your runs. The only time it stops is when you recharge. This is a hint something is up. If you hover above it what does the popup say ? try moving along the line and observe whether the information changes
There shouldn't a foreground process running when you're not using the phone. Maybe if you can screen shot, the table that displays under History Stats - Foreground Process Summary
Scroll down and under the graph and on the left you will see three headers with twisties, System stats, History stats & App Stats
Hold on to your bug report files and they will be useful to verify if any changes you make take effect or not
- 1% per hour corresponds to second screen on, with it off your drain would be halved. However having drain after leaving a music or browsing app isn't good. It means a wakelock was caused and its not releasing so doze can't kick in. So battery will drain. If the phone is shaking, say in your pocket as you walk around, full doze won't kick in either
Which social media apps do you use.
Stock launcher or other if so which
I've found just buying a new battery off of ebay for $10 is the the easiest way to gain back that extra hour of on screen time and extend stand by. That's why the phone was made with a removable battery. I have 3 of them and don't need to touch a charger for a week. and when the time comes to charge the batteries, just put them in the charging docks and done.
