My galaxy S2 couldn't last a day and I tried my best to figure out what was the problem. Every time I go to class and put my phone in my pocket my battery would drain rapidly from 100->75%. I checked my CPU spy and apparently my phone wont go into deep sleep mode. No matter what ROM or kernel I use, my phone wont go into deep sleep mode unless I reboot my phone every time I unplug it from the charger... this irritates me so much.. Is there a way to activate deep sleep mode right away?
Are you using a sammy charger and cable? Some third-party chargers and cables cause a wakelock. Apple compatible products will almost always cause a wakelock.
I have found that plugging the phone into a running PC USB port, even for just a moment, will usually clear the wakelock.

Hi..I had a similar problem before, Im using cpu sleeper app, and installed CPU spy app to see if it was going into deep sleep. and that took care of it.Phone must be rooted.Good luck
Gsam from play store will help you find out why your phone isn't deep sleeping. It will show you what app or apps are holding your phone awake.

Hello I am running a gingerbread rom. I use cpuspy to monitor what percentage of the time my phone is sleeping. There is a program that is keeping my phone from sleeping but I don't know what exactly it is. Spare parts does not work for gingerbread. I have the phone unplugged and my phone still does not sleep. My phone does sleep some but something is stopping it from sleeping all the time when my phone is not in use. Please help. Thanks in advance.
P.S. I freeze google talk and I believe that fixed my problem.
Hello,
I need a simple app to help with an overheat problem on my EVO.
Let me recap the problem simply, when the phone gets too warm it will shut down and vibrate five times and then blink the green LED. The phone then cannot be turned back on until the battery has cooled down.
I have found a half solution, if my phone is in Airplane mode then it will not shut down even when it is warm. So, to avoid shutdown, I need a simple widget. The widget should be 2x1. On the left side, a simple battery temp monitor. On the right side, an airplane icon to let me know if the phone is in airplane mode or not.
What I need the app to do is to automatically switch the phone to airplane mode if the the phone gets above a user designated temperature. The only exception to the automatic airplane mode should be if the phone is in a current call. Seems like the phone will let me finish a call before shutting down due to heat. Hopefully the app can throw the phone into airplane mode immediately when the call ends. But if that exception is too difficult, the primary functionality would still be worth it.
This is my first app request, so I don't know if I'm being specific enough. I also know that other people can use this app. Hopefully someone out there can help us all out.
Thanks
There is an app called tasker that should be able to do that for you. At least untill someone can build an app for you.

Not sure what your doing to over heat the phone, but I would try to fix the problem instead of usong a work around. It sounds like you have an inefficient kernel or its too far ovrrclocked. I'm thinking continual use in this overheated state will cause unrepairable damage to your phone.
Just looked at Tasker, from what I can tell it does not have Temperature as an event.
And the problem cause is not my kernel, from what I can tell. I've tried a few different kernels on a couple different mods. I've tried underclocking and under volting. Nothing seems to help. From what I've read, I might have a faulty sensor.
I had a hell of a time with cm7 and the jit compiler. Poor battery life and running warm even when browsing the web. Not sure what your running but it may be as easy as tapping a checkbox.

It's a hardware cpu sensor calibration issue, according to Sprint tech Lokifish Mars. Search for my thread in Evo General.
I avoid shutdowns by keeping battery temp < 39°C.
mine overheated when i was charging and using hotspot/tether, somehow after i wiped my sd card and everything else and installed the rom again it never overheated again.
somehow the more apps get installed the more the chanse some of them be are gonna be running in the backgroung, who knows...

Some phones overheat and shutdown regardless of installed apps, rom, or kernel. My Evo consistently shutsdown at 39°C, even when running bare aosp w/zero apps installed.
It's only an issue for me when playing games, using the phone in high ambient temps, and flashing mods. Keeping the battery & cpu cool with a fan or ac vent is the only way I can flash mods or roms.
Elixir is a free app on the market, you can make customizable widgets (1x1 up to 4x1), one for temp, the other to toggle airplane mode.
I use it to monitor temp, battery, cpu freq, and cpu %, and to keep an eye on ram.
Works well.
Tried CM9 RC2 and Full Throttle 7.1, the same thing happened:
I unplug my phone in the morning after browsing for a few things, then left the phone basically idle for a few hours. Then use it for a few minutes of different activities. For the first few hours the phone goes into deep sleep, after I use it for a few minutes the phone will refuse to go into sleep again, awake until I restart it.
I have been using CPU Sleeper to force the phone into sleep, doesn't really help at all.
Any clue?
Install Better Battery Stats to help determine if an application is keeping your phone in wakelock.

Thanks! it's a great app! trying it now!
any luck?
not yet, seems behaving as expected after installing the app. Still deciding between CM9 RC2 and Full Throttle 7.1, so may need a couple more trials to point things out.
Is it normal for this phone not to deep sleep? I installed CPU spy and it shows that it always stays at 300mhz when the phone is idling. I have all apps closed in the recent apps tray and my phone is stock. Just wondering if this is normal. Thanks
I've been wondering the same thing... battery seems fine and none of my apps or keeping the device away, so I'm assuming it's the whole dt2w feature they have on it. Plus, they mention a "sleep mode" on the HTC website, so maybe they got their own thing or something...
Any info would be nice.
EDIT: Apparently, while charging the device, it will rarely go into deep sleep mode. After I took it off the charger, it was going into deep sleep exactly like it should.
Anyone notice problems with the NY Times app recently? I noticed some high network activity out of my Note Pro over the last few days, and dug into it last night. Turned out, my tablet never went to deep sleep, and looking at battery usage, the NY Times app was behind only the OS and System.
I can't uninstall the NY Times, but I can revert to the factory image, and that seems to have put a halt to the network activity, and also the tablet is now going into deep sleep again. So it looks like it was an app update, somewhere along the way?
What's deep sleep as opposed to sleep as opposed to going into airplane mode?? Your posting about the ny times and sleep is difficult to understand.

Not difficult to understand at all, this is apparently a wake lock issue with the application.
Tapping the power button to turn off the screen puts the device in sleep mode but CPU speed still varies as background activity continues. Application processes can place wake locks on the CPU to keep it from going into deep sleep which is the lowest power consumption setting. A device that never goes into deep sleep will experience higher battery drain with the screen off for extended periods than one that does go into deep sleep. Sleep has nothing to do with airplane mode, which turns off all radios and has no direct impact on CPU.
First thing I would try with the NY Times app is turn off all notifications for it. Personally I don't use it and have it frozen so I can't verify the wake lock issue on my device.

Much better explanation than I could have given, thanks! So wish I could root my tablet (a Verizon...), feel like I'm trying to debug things with both hands tied behind my back!
So far, the NYT problem hasn't come back - can't freeze or uninstall it without root, but have removed it from Magazine UI and basically backed out all updates by restoring it to its factory image and clearing its data. BTW, it was set to only get updates every 4 hours. Obviously it had a different idea.
Yeah I hate it when apps get like that.
It's times like that where I'll use Greenify sparingly to push the misbehaving app into hibernation. Otherwise I'll just let android do it's thing.
A few days ago, I noticed the NY Times app only it's you view 10 articles for free every month. I was going to say, why not trash that garbage? It requires root, though, since it's actually a system app. That is just profoundly stupid.
At least Samsung didn't pick CNN as it's news app, amirite?
