Tab stays at 216mhz instead of Deep Sleep - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

Hello, I have installed the app CPU SPY to monitor the Deep Sleep of my tab. I have left it alone for about 2 and a half hours but only 4 minutes is gone to Deep Sleep.
I have WIFI OFF, Flight Mode ON.
How can I check these things ?

There exists an app that you can download which will show you what is keeping your device awake, and as a result, running at 216mhz. The app and a lot of documentation about it can be found here:
http://forum.xda-developers.com/showthread.php?t=1179809
There is also a separate app which puts all but one of your CPU cores to sleep when the device is not in use. I've installed it on both my phone and tablet and it works great.

Thank you for your reply.
I have installed the BetterBatteryStats, please let me know where should I focus mostly to find what is causing this. Thank you.

I notice if I go into settings, sound, system- and turn off the touch sounds, the screen lock sounds, and vibrate on screen tap that the tablet goes right into deep sleep. It helps the battery a lot but it's still a bit worse than CM9 roms.

[Q] cannot wake up from sleep

Hi,
my new archos 101 often cannot wake up after sleep (deep sleep or screen timeout).
tried many methods: wifi disabled, battery booster, flight mode, sounds disabled... no luck.
i installed new fw, 2.1.8 and arctool with markets and google app and some games.
uninstalling maps and disabling wifi location didnt help. whats strange, is that sometimes screen turn on after 30s+ seconds..
i am new, but is there any way to check what's a process blocking it?
write to logs or connect via usb and check?
help very much appreciated
I'm having the same problem...
I just keep pressing the on/off button until the screen turns on. Didn't find a fix yet.
>>> i installed new fw, 2.1.8 and arctool with markets and google app and some games.
those were my 1st steps with archos, so dont know if it works in previous firmware.
right now, i dont want to do hard reset.
There is allready a discussion about this.
It seems that after the press, the archos is waking up, but the displaylight itself doesn't come up.
If you switch the display to abough 30% ( Settings/Display ) this doesn't happen again.
NOT kidding: the Archos has trouble turning on when cold. Try warming it on the radiator if its <15 degrees celcius.

success!
turned out, it is TRUE... 30% solved it!
btw, pretty ridiculous bug..

30% of what? Increased brightness? I went to settings/display and couldn't find percentage level
As i don't have an english version, i can't tell you what you should read there,
but which other setting in display has percentages?
no % displayed, but just set if for 1/3 of the progress bar.
Jeezus, i cant believe it, but i can confirm that it's a brightness setting issue. It's so ridiculous but it's true. I have been frantically trying to find a solution to this problem for the past 30 mins, and turning the brightness setting to 40% worked to restore the screen after the soft sleep mode, when previously i had to keep rebooting the damn thing by longpressing the power button. THANKS A MILLION, GUYS!
Ohh i see i am not alone = ]
Thank you for the Workaround!

[Q] High Awake time and no explanation why, only few wakelocks and alarms?

I don't understand my high awake time. I posted some samples. I've much more awake time than my display is on, but I don't understand why.
Kernel wakelocks are about 15 min total, Partitial wakelocks are about 7 minutes, only a few alarms. My Processes consume only seconds of cpu time.
How can i find out what is reponsible for this high awake time? Are there other tools than BBS, CpuSpy and Elixir2?
Is there any way to monitor the phone during sleep/standby what causes awake time?
Your pictures didn't come.
Is sync on, running a location program? Installed any apps recently?
Sent from my GT-I9300 using xda app-developers app
Pictures are now available. Sync is on, no location Program running. No New Apps
Your WIFI is running all the time. Might want to turn on option in advanced settings to turn off wifi automatically after screen is off few mins.
Yep, WiFi. And is your GPS on? If your network provider doesn't offer fast dormancy, you should go on and disable it also.
Sent from my GT-I9300 using xda app-developers app
are you using apps like screen off or something like that?
Wifi off has no effect on awake time, GPS is only active when used. VF provides fast dormancy.
What causes awake time? I see nothing in BBS?
I use a screen off app. But i don't see any difference when using power button, screen off by app or timeout

I've no problem with battery drain. Overnight with wifi connected (no 3g data) consumes less battery than 3g connection.
My problem is the awake time because i dont' see any cause why this is that high.

That is the culprit
Screen off app dont put your phone into deep sleep but instead it turns off your screen but still awake, meaning use physical power button if you want to put your phkne into deep sleep. And also make sure you close all apps in the multitask or recent apps

I tested it. There is no difference beetween power button and my screen off app (force_lock permission). Both shut down the device and enter deep sleep.
Any other ideas?

I supposed your using BBS? You told me that when you shutdown the device it enter deep sleep? So how in the world you have high awake time if your phone is in deep sleep?
Here try this:
Make a BBS widget in your homescreen bcoz it is more understandable than entering the app itself. You will see deep sleep time and awake time and screen on time in there. Then try to shutdown using power button then after 5mins check if your deep sleep counter goes up, then try your screen off app then after 5mins check if deep sleep counter goes up if not then its different.
Or maybe your wifi or mobile data is on gps is active.

Long Battery Life Fixed for all ROMs

Think I have a solution for short battery life for Nook! (Really for any android device)
The problem has been that the Nook Tablet does not go to a Deep sleep (even if they say its fixed its not). Every night I have to charge the Nook battery because it goes from 100% to 90% overnight. If the Nook sits all day with no use the battery will drop to 85%. Almost a 20% decrease in power in one day of no use. By the second day battery is down to 50% and forget it if I use the Nook.
This app seems to solve the problem!
I downloaded a free app (Google App store) called “CPU Tuner (rooted phones)” you need to be rooted but for most of us here this is not an issue.
This app allows you setup CPU speed, WiFi and other settings for different states the Nook may be in.You can setup several triggers but I only used 1. The problem is not just having the Nook go into Deep Sleep but to turn off other functions that hit the battery e.g. WiFi and sync. With this app you are able to tell the Nook to go into Airplane mode as well as turning off all other features that may consume battery life. Below is my setup and findings.
State 1: “On Power (Plugged in)” WiFi on, Sync on, airplane mode off and CPU set to 1020mhz Governor set to interactive
State 2: “On Battery” WiFi on, Sync on, airplane mode off and CPU set to 1020mhz Governor set to interactive (same as above)
State 3: “Screen off” WiFi off, Sync off, airplane mode on and CPU 600mhz Governor set to conservative
State 4: “Screen Lock” WiFi off, Sync off, airplane mode on and CPU 600mhz Governor set to conservative (Same as above)
With these settings (and having 3 nooks with CM10 to test) here are my numbers
test stared around 10pm
Nook 1 started with 76% batt (CPU Tuner not installed)
Nook 2 started with 85% batt (CPU Tuner not installed)
Nook 3 started with 90% batt (CPU Tuner installed)
checked battery life at 8am next morning.
Nook 1 65% batt
Nook 2 75% batt
Nook 3 91% batt (Yes it went up 1%)
Later in the day with no use 8pm still 91%
Loaded CPU Tuner on all three Nooks started test at 10pm. (Day 2)
Nook 1 started at 96%
Nook 2 started at 74%
Nook 3 started at 83%
Checked battery life at 8am next morning.
Nook 1 ended at 96%
Nook 2 ended at 75%
Nook 3 ended at 83%
As you can see this is a big difference then losing 20% power overnight. Since I have Screen Off and Screen Lock as the same trigger I don’t lose power if I am just checking batt level or the time.
This is a MUST HAVE APP. easy to setup and makes a big difference.
You can also setup it up so that if you are on the battery the CPU is at 1008mhz which will save battery life while in use and when plugged in CPU can go to 1020mhz giving you full power.
Sorry for such a long post but I felt it was good info for the users.

Terrific recommendation. Was easy to set up and works like a charm. No more finding my Nook with a flat battery after ignoring it for a couple of days.
Gracias! :good:
Thank you for the tip! I will make a note of it so I can use it if/when I need it! It seems very handy to be able to set upp different user schemes!
However, I do not agree with this comment:

I do know it's a problem in some ROMs, and often a problem along the way during development. I think it's grocely unfair to suggest it's a general problem though.
I'm running a CM10 build from 1231 and I have not problems what-so-ever with battery life! I hardly loose anything while on standby (wifi off). I do turn it off manually, and I understand that with this app I can have it done automatically which is very neat, so might use it because of that. The processor speed adjustments works just fine anyway in the ROM i use.
It's great to know this thing exists and does work if I want to try a "work in progress" ROM more extensively. So once again :good:
The "battery-drain while asleep" problem got fixed since early December (e.g., Succulent's v12/08 build).
Also, I simply turn off WiFi (using a WiFi on/off widget) when I am not accessing Internet, and my NT's battery consumption while asleep has been well below 1% a day (comparable to that of my Google N7).
Finally, for those who are interested in battery consumption management tools, I find Battery Juice Defender (which I use on my Samsung GS-II phone) reasonably effective yet easy to use.
Sorry it was not meant to be a dig or insult!!!
I love ALL of the work that the developers have done and I think I have changed my ROM about a half a dozen times because I can't figure out which one I like best. But compared to my wife's Nook with just the B&N ROM her battery could last days where my battery only lasted 1 day.
Please; I did not mean anything insulting with the comment and the fact that these developers can put together such solid ROMs is saying something about their skills.
How I found this App was from posts here where users were saying that they had to turn off WiFi. Trying to make a WA or KA (WA = Wife Approved and KA = Kid Approved) I know that going in and turning on and off WiFi was never going to happen.
When installed the CPU Tuner and found that it was going to do this automatically and on top of this battery life goes from 1 day to several days I had to make a comment. Only after a few days of my kids using the Nook with the CPU Tuner they made comments about how long the battery lasted. Using these ROMs and CPU Tuner made the Nook 100% WA & KA and now wife is using Nook with the Hashcode ROM and I have heard no complaints. Happy wife, happy life.
Again sorry
Can you post screenshots of your settings from the start, there are some things in your OP that i can't get to setup for testing purposes, indeed the battery of my nook using @succulents ROM 4.1.2 final drains battery considerably while sleeping.

V;
I have uploaded the screen shots. All settings can be changed after loading so if you select the wrong item its not a problem.
I try to keep it simple, You can have more then 1 configuration but as you can see I just use 1. I set my user experience to Normal which can be changed in the settings.
Once you start CPU tuner you will see the current state of the Nook. You can select a different state. (Note the battery was at 52% which has been at 52% for about 2 days and just charged it this morning.)
Next you will see triggers; here you set what Profiles you want for different states of the Nook. Just tap in that section. I forgot to take a screen grab. But I have battery at 100, "On Battery" = Normal, "Screen Locked" = Powersave, "Screen Off" = Powersave and "On Power" = Performance. "Battery Hot" = Powersave and "Call in progress" = Performance. I really only need two profiles Performance and Powersave my Normal has the same settings as Performance and my Screen Off (which I don't use) has the same setting as Powersave.
Next are the profiles. tap the profile you want to edit. See screen shot 7-10 these images have my profile settings. I don't trust airplane mode to really shut off all that I want off so I make sure that things I want disabled are disabled and when I go into Performance I disable airplane mode and enable WiFi (Not sure what Background Sync is or if it even works on the Nook most times I keep it off especially for the "Screen Off" and "Powersave" profiles)
For the governors I leave it as interactive for "Full Speed" and "Normal" settings and conservative for "Save Battery" and Extreme Save Battery these may be the default I am not sure.
If I wanted to really go crazy. I could set my Normal CPU speed to 1008mhz to save battery life while on battery. I could also setup it up that if I have 100% battery use Performance Profile and when the battery level drops to 70% use Normal profile (with CPU at 1008mhz) and when the battery goes to 60% then create a new profile which lowers the CPU speed even more. But with my current setup I am very happy and the fact that after a few days of no use the Nook still has the same power level from when I last had it on.
That's about it. If you have any questions let me know.

Is there any way to delay (eg I want it to wait 5 min before turning the WiFi off)? Or should I use tasker or automateit for something like this?

You can setup a profile where if you press the power button the CPU speed is reduced and turn off all features except WiFi. I believe that after 5 minutes (or what ever time you have set for "Sleep" I believe the default is 2 minutes) the Nook will go to sleep and all features for Sleep will take over e.g. No WiFi.
This will give you two Power options:
1. let the Nook go to sleep on its own after 5 minutes (Screen would be on during this time killing battery life)
2. Press the power button and screen turns off but WiFi is still on and after 5 minutes sleep all features off.
You can monitor what it's doing by pressing the power button and waiting about 6 minutes. Then go to the CPU Tuner log (shift pages to the left until you see the log page) What you would want to see is the following:
11:08am ALL-> Performance
11:07am All-> Powersave
11:01am All -> Screen Off
11:00am ALL-> Performance
Please note that since the time is only shown as hours and minutes it possible to see settings with the same time stamp.
Good Luck.
If you have any questions please let me know.
Fantastic, exactly what I am looking for :good:
I must say that the OP was very good, and CPU Tuner is a great app ....
but times, and apps move on.
currently I use the free "Battery Doctor" from Google Play which does what Tuner can do, but in a much user friendlier way.
my tablet only loses 1 to 2% overnight and still has 80% or so left if not used for a few days.
the developer also has a great file cleaner utility which i also use, and the Task Killer, and memory cleaner widgets you get.
in my opinion they are MUST have's, and I no longer even use the paid version of Juice defender that was my favorite app.

I'm running CM11 Snapshot M3 and haven't been able to find a user friendly way to automatically get wifi off during sleep.
The built-in "turn off wifi during sleep" setting does not seem to be working.
Battery Doctor (Battery Saver) doesn't seem to work well on this ROM. After installing, it would seem to let me change the screen brightness (the slider would move), but then it would revert back to 20%. The app then crashed, and attempting to run it again after rebooting results in a black screen of death.
I've tried a couple other apps like WiFi Auto-Off and Advanced Battery Saver - Free, and neither succeeded in shutting off wifi during sleep.
Granted, I did not try CPU tuner with this ROM. I've tried it in the past and found it very unfriendly.
Anyone have a user friendly method to automatically get wifi off during sleep on CM11?

I just use the available quick toggles in CM11 to manually (1) switch off WiFi and (2) go to sleep.
Yes, there is a quick toggle for go to sleep.
I've pretty much have gave up on ever having great battery life on my Nook. Just the nature of the beast Still a great little tablet
Since all those apps automate disable wi-fi when system sleeps and you won't get any notifications if android apps. try to poll data from internet, I just set wi-fi to automatically turn off in android wi-fi advanced menus, there is no need of any of those apps since android system can do the same thing.
Nookt Tablet goes Nuts less than 50% Battery
Currently running CM 11 snapshot 5
Whenever my nook gets below 50% battery it goes nuts. apps open themselves, then shut down, windows open, if I am watching a video it stops then begins at the beginning. Weird.
Have had this issue before and was hoping with the upgrade it would stop, but no dice.
Help?

Does Android Doze work differently on the S9+?

With my Note 4, it would wake up from Android Doze, or simply not enter that state if there was movement of the phone. I felt stupid needing to pick up my phone every 10 min to give it a small shake, but at least it seemed to work. I keep my phone in my pocket when I'm working outside and that always kept the Note 4 from falling into Doze mode. Not so with the S9+. It drops into Doze even in my pocket. Anyway to stop that from happening? Like others here, I feel frustrated needing to activate my screen to find out if there are notifications.

That's not Doze mode. Doze is when Android puts apps to sleep that are in memory not being used. This is done to save battery (and processing time?).
So what is happening here, if I understand, is that your phone display is going blank when you pull it from your pocket?

Doze was originally described as putting your phone into a power saving sleep mode after 20 min of "inactivity". The issue that caused me problems back then was not about the apps, but that notifications pushed to the device were queued up by the system until your phone "woke up", then the notifications would come rolling through. This happened at the system level regardless of app.
Perhaps in the latest version of Android they have changed the definition of Doze, but another poster was having a lot of issues with notifications (mostly email) and the culprit was deemed to be Doze.

No. My display is blank (as it should be) when I put it into my pocket, as well as when I pull it out. I always shut the screen off before putting my phone down, or in my pocket.
If I put my phone in my pocket, and 5-10 min later I get a notification, it comes through loud and clear and I pull my phone out and check it. If 20+ min has gone by without me having a reason to turn the screen on, then I stop getting notifications. When I pull it out to check the time or send a message, suddenly the notifications come rolling through.
Again, I was used to this if the Note 4 was put down, but this behavior is new to me if the phone is moving about.

I concur. Same happens to me.
I don't have this issue at all. I have my phone in my pocket most of the day and don't need to "wake" the phone up for notifications. I can leave my phone unattended for hour or 3 and it still receives the notifications without issues. I don't know if I have turned on a setting that mine works different, but I must say that my battery life isn't that great....as if the phone never sleeps/doze at all

AoD could be keeping your phone awake, preventing Doze. The power saving features talks about putting apps to sleep, so unless you use them, that could also be disabling Doze. I could try changing the power saving settings, though it seems like a shame. I have zero interesting in AoD for multiple reasons, so it's not worth it for me to use that to solve my problems.
Thanks for the information!
Doze changed in Nougat, I believe, so that motion no longer prevented Doze from working. Since most men, at least, carry their phone in their pocket Doze hardly ever kicked in, greatly limiting its power saving capability.
You can exempt specific apps from Doze if you want to get notifications from them even when dozing.
Settings / Apps / 3 dot menu / special access / Optimize battery usage. Select All Apps from the drop down. Turn off the toggle for any apps you don't want to Doze.

Doze was originally described as putting your phone into a power saving sleep mode after 20 min of "inactivity". The issue that caused me problems back then was not about the apps, but that notifications pushed to the device were queued up by the system until your phone "woke up", then the notifications would come rolling through. This happened at the system level regardless of app.
Perhaps in the latest version of Android they have changed the definition of Doze, but another poster was having a lot of issues with notifications (mostly email) and the culprit was deemed to be Doze.
No. My display is blank (as it should be) when I put it into my pocket, as well as when I pull it out. I always shut the screen off before putting my phone down, or in my pocket.
If I put my phone in my pocket, and 5-10 min later I get a notification, it comes through loud and clear and I pull my phone out and check it. If 20+ min has gone by without me having a reason to turn the screen on, then I stop getting notifications. When I pull it out to check the time or send a message, suddenly the notifications come rolling through.
Again, I was used to this if the Note 4 was put down, but this behavior is new to me if the phone is moving about.

Yes, I am confusing Doze with the Samsung power saving options. Blah!
I know the battery life will decrease with aod, but I have noticed that even without aod on my battery drop 2% per hour, so I leave it on...There are days that I can go 1 day and 8 hours before charging, but then my sot is only 2 hours....In general I'm happy with the battery life

Thanks!
It seems oddly redundant needing to do essentially the same thing in two places. One well advertised under the battery settings, and the other one hidden under settings/apps/special access.
Hopefully this will fix my problems. Glad to know there is a work around.

The two settings really are doing different things. Samsung's (in the battery settings), puts apps to sleep after 3 to 7 days (depending on your settings). The won't wake up again until you use them. Doze (the pretty much hidden option in Apps), lets the apps wake up on their own, when you start using the phone, even if you don't access those particular apps.
I'm not sure why the Doze setup is buried so deep in settings, though. I guess Google (or Samsung?) really doesn't want you interfering with it.

I made a mistake of putting an app to sleep that I use to keep my screen awake. It uses a widget to toggle it on/off, but will shut off along with the screen if you intentionally shut your screen off. After putting that app to sleep, the widget stopped working. I had to go find the actual app, start it, then quickly flip back to my home screen and click on the widget. I couldn't undo my "sleep" action on that app. I changed it to "unmonitored", so that the S9+ would never put it to sleep. I rebooted. I shut off the power saving options. Nothing worked. Everytime I would go to the widget (unless I just started the actual app), it wouldn't react to clicking on the widget.
I finally gave up and uninstalled the app from my phone. Rebooted. Reinstalled it and now it works fine. So I'm not sure I agree with "puts the app to sleep in 3 to 7 days". Maybe 3-7 minutes...
Well, 3 to 7 days is what Samsung says, and the optional range you can set in the app. Don't know what specifically happened with that widget, though.

Where is the setting(s) for optimal range? I don't remember specifying that. I thought it was more of an on/off thing. White listed (unmonitored resource consumption) or black listed (never let it run in the background). Then apps in neither list it reports to you and you can force them to sleep or not.

Samsung does bury things....
Settings / Device maintenance, click Battery at the bottom.
Then click the 3 dot menu at the top, and Advanced Settings.
Tap App power monitor (the text, not the toggle).
Tap Put unused apps to sleep (again, the text).
You can set the slider anywhere between 3 days and 7.
I spent several days just wandering through every settings option I could find after I setup the phone. Discovered all kinds of hidden things. Sometimes I can even remember where I saw them.
