This is my first post, hope you can understand what happens to my phone (SE X10 mini pro - U20i).
When I connect it to my wall charger, it starts charging normally, no problem. If I charge it overnight, what it is supposed to happen is that it charges to 100%, then it stops automatically the charging process, "waits" untill the battery drops a given percentage, not sure how much, and then charges again, and repeats this process until I disconect the phone. This is the normal process, and usually does this.
But some times, what it does is charging to 100%, stops charging and it remains in the 100%!!! Never drops, and it discharges the battery much more rapidly!! I have System Pannel, and when this happens I see that the processor is allways in the 10%, which is not usual in standby... and as the battery is discharging, the % doenst change, still shows 100%, when it is maybe in the 3800 mV. When I disconnect my phone, the % starts decreasing rapidly, as if it was trying to "compensate", ah in maybe 30/60 minutes reaches 50%... This is not normal, and I think it is some process that stops associating the % of the battery with the voltage.
Ever heard of something like this...? My phone is temporarily rooted with Z4mod, with stock firmware. 2.1
try this:
install xrecovery
make sure your battery is at 100% (let it charge over night)
go into xrecovery (press back while the SE logo appears while booting)
go to "advanced options"
delete battery stats
and drain your battery till your device turns off, doesnt matter how
No go. Doesn't solve it... Going to try to charge it tonight with the background data option turned on. Have it turned off to save battery. Probably won't solve it, but it doesn't hurt to try.
This weekend I've charged it WHILE turned off, during the night. Got it off the charger, symbol in screen appeared with full charge, turned it on, it immediatly shown 18% battery left... This is really weird. Can it have anything to do with not using the original charger? I'm using the original as a travel charger, in my bag, in case I need it at work, and at home I use a Nokia charger, with an output of 890 mA, and with the adapter to microUSB (which actually gets very hot). Do you think it can have anything to do with this issue?
Turn off data traffic and "sync now", you will save battery.
With data traffic and sync on, my phone last just one day ( about 24h ).
With it off, It last about 2 ~ 3 days.
Result: I just turn it on, when is needed.
try turning off data traffic and as ur phone is rooted use SetCpu and auto killer memory optimiser....nd never over charge ur phone....charge it only when the battery is <10% and charge it until it gets completely charged....nd as soon it gets charged disconnect it.....nd set the SetCpu to ondemand and auto killer to optimum...see if that works for u..
lso get ur battery checkd if thats ok...
Hello together,
I'm new on the board and I have a question. I hope somebody can help me with my problem.
I have buy the Samsung Galaxy SII PowerPack and now i see that the Galaxy doesn't change the CPU Speed to Deep Sleep.
The Same is when i Charging the battery with the charger.
Have maybe somebody a custom rom or Something else where the CPU go into DeepSleep by charging.
In Some other forum i Have read that the battery need the CPU to control the loadvoltage? Are this possible?
If i do nothing with my SGS II the PowerPack will be empty round about 9Hours because, the SGS II it's on a charger and the CPU are work bye 200MHZ
I Hope my english is not 2 bad.
Thank u 4 u're help
You should get those 9 hours from the standard battery easily. Have you tried the standard battery to see if you still have Deep Sleep problems?
It's often just some app eating away batterylife.
Hy prodygee,
If i doesn't charge the battery by AkkuPack or Charger my phone works with the deep Sleep Mode!! Test by CPU Spy.
U can test it also. Connect u're phone to the charger and u will the the von doesn't go into Deep Sleep or u must correct me
I mean if the phone and akkupack 100% loaded i have the message "full loading" for 9hours. After this time the Akkupack is empty the message is away and my phone have 100% at this moment. After this time the Deep Sleep mode works fine!!! Because no charging!
That is because those power packs just keep charging the phone. You can't expect it to go to deep sleep.
On a side note since that is just keeping the phone battery charged it is actually wrecking the phone batteries life by reducing its recharge cycles. Which is why you are supposed to unplug the phone when it is fully charged.
For the Samsung Galaxy S1 there was an ON/FF Button.
My Question is, give it a custom Rom or something else what stay my phone in deep sleep by charging? Or is it a Hardware problem
I've posted a comment in a few other threads, but I think this is worthy of its own thread now to track if this is a common issue. Here's is the situation:
Good:
I charge the phone using the wall charger, take it off, reset CPUSpy stats, check it an hour later and find that it has been deep sleeping as expected.
Bad:
I charge the phone using a USB charger (computer, USB to cigarette lighter adapter in car, etc.), take it off, reset CPUSpy stats, check it an hour later and find that it has NOT been deep sleeping as expected.
I have let the phone sit for hours and it never goes into deep sleep, it just sits at the lowest stepping (384 mhz). If I reboot the phone, it's fine, and it deep sleeps immediately. It continues to work until I plug it into a USB charger again.
Some people were reporting this issue with the overclocked kernel, but this is happening to me completely stock. I'm on my second Note and it's happened on both.
Here are some things I have tried to fix it that have not helped:
1. I have rooted using the system partition ODIN method (meaning I am still on stock kernel) and frozen all the bloatware. This has had no effect.
2. I plug it into a wall charger for a few minutes, then take it off, reset CPUSpy, check it a bit later and it is still not deep sleeping.
My next step is to see if it is a third party background app that is keeping it awake, but I doubt that is what it is. I'm going to try killing them one at a time to see what happens. It's probably a core OS process which is why only a reboot fixes it so far. As a separate test I will try flushing the RAM out with the task manager, and seeing if that fixes the issue.
I've also installed Better Battery Stats, so hopefully it will show me a wakelock of what is causing the issue.
More to come....
Hmmm, looks like plugging into a wall charger may have fixed the issue but had a delayed effect. I checked it 5 minutes after and no deep sleeps, but now 20 minutes later and it is starting to deep sleep. I just reset CPUSpy again and will continue to monitor it.
Unfortunately I have no way to plug into a USB charger until tomorrow to cause it to mess up again, so if this fixes the issue I won't be able to test any other workarounds. I don't consider plugging into a wall charger a good workaround because we don't always have those handy.
So before it started to deep sleep I checked Better Battery Stats. After having my phone unplugged for 6-7 minutes, I have a kernel wakelock on sdio_al for 5 minutes. I'm not having much luck finding out what sdio_al is....
Update: It looks like plugging into a wall charger only half fixed my issue. It is now doing about 50% deep sleep and 50% 384 mhz. I now have an 11 minute wakelock on sdio_al and an 8 minute wakelock on PowerManagerService. The phone has only been off the charger for maybe 20 minutes or so and these are the stats since then.
Both of these numbers keep climbing as time goes on.
So after some googling I believe SDIO_AL has something to do with the SD card, specifically with a type of sd card called SDIO. Since this is only happening after a USB charge, that kind of makes sense. When you plug into a USB charger you have the option of presenting the SD card as mass storage to the computer, whereas with a wall charger that obviously isn't the case. So maybe some process that's sitting there waiting to mount the SD card if needed is stuck and keeping the device awake?
I am experiencing the same thing. I am Rooted but haven't loaded DG's kernel.
What I am doing is a battery pull following a full charge and no USB connection to confirm its the USB connection. Checking my wake locks turned up nothing. Even with the deep sleep issue I am getting 16 hours with 50% brightness and 3 hours screen time 2 hours talk time.
I experienced about 5% deep sleeps pre-root, but mostly it sat at 384. That pretty much confirms what you've been finding. Last night I rooted and installed Da_G's non-oc kernel and now my phone deep sleeps usually within 30s of setting it down.

I had an old version of Better Battery Stats that only showed partial wakelocks, and mine was empty as well. I had to download the newest version and look at "kernel wakelocks" to see the SDIO and PowerManagement ones.

After you installed Da_G's non-oc kernel, have you done a USB charge since then? I suspect you have not. I don't think the kernel fixed your issue so much as the fact that it was rebooted.
If you have USB charged it and his non-oc kernel DOES deep sleep, then his kernel fixes a bug that is present in stock.
I'm using Non-OC kernel from Da_G too. My phone is about 3% deep sleep. 97% is at 384Mhz. Not sure what happened

Have you done any USB charging? If so, reboot and see if deep sleep gets better.

Did both wall and USb charging. Same thing, probably wakelocks somewhere
So everything I tried wouldn't stop the wakelocks nor the failure to deep sleep, so I rebooted the phone. And as expected, it is now deep sleeping the entire time and no wakelocks.
I'm hoping someone knowledgeable of this SDIO-AL process can figure out what is going on. does anyone know how to report this bug to Samsung?
I can confirm this is true on mine. Lots of sleep all day long after coming off of the wall charger last night and then cold starting it this morning. Charged it from my combo car bluetooth/charger (which acts as a USB host so it can play songs right from a USB drive) on the way home, unplugged it and reset the timers in CPU Spy. After 10 minutes it was over 90% @ 384 with no sleep at all. Plugged it into the wall charger for a few minutes, unplugged it, reset the timers, after just 5 minutes it was back to mostly sleeping again.
I do not have this problem with Da_G's rooted kernel - I only have this problem with Da_G's O/C kernel. I beleive he is working on this problem - some amazing work he has turned out so quickly.

I am running the O/C kernel and the deoxed rom. I was having the exact same issue as everyone is having with usb and sleep. I wish I would have written down what I have done this evening but, fumbling around in the system, I have fixed it.
What I can tell you for sure if I have it set at 192 / 1.76 using Rom Toolbox and also uninstalled EVERYTHING at&t related except wifi sharing, and EVERYTHING Samsung except S-Pen apps and the Samsung keyboard and swype.
Using CpuSpy, 5 seconds after power / screen off, it will go from 1.7 to 192, then into deep sleep a second later. I let it sit for 15 mins and it stayed in DS until I woke it. i wish I would have made specific notes. But I can confirm that mine will DS using the OC kernel, but I have UN-Installed a lot of stuff that was in rom (and possibly running in the background). Everything still functions, Wifi / Gps, etc and I haven't observed any negative effects yet.
If someone can tell me how to dump my config so you guys could compare and see what I did, if it might have been some rogue process that was causing issues i'll be glad to help. BTW, I am no developer just a geek with a lil linux knowledge and not afraid to tinker..
I can't imagine I could hard brick the device uninstalling services anyway, since I imagine the recovery routine is in with the boot-loader which i'm not messing with, but tell me if i'm wrong...
Edit: one thing I have noticed, that even though the Note is still connecting using MTP, it no longer does the media scan, but I can still access both storage areas fine from the pc. Before my tinkering, no matter how I charged my phone, via wall charger, or computer that media scan would run no matter what, now its not... That's one change I DO like.. usb access seems quicker too.
Ok, I would like to see if I can have someone confirm my test.
Test 1:
1. Charge VIA computer USB or charger to 100%
2. Remove from cable, cradle etc...
3. Immediately open CPU Spy and Reset the Timers and close CPU Spy.
4. Place into Sleep Mode by pressing the Power/Standby Button
5. Wait 10 minutes and go into CPU Spy and note Deep Sleep time.
Please provide the following
1. Charging Type USB to PC, Samsung Cable and Outlet Charger or Third Party Charger.
2. Deep Sleep Time 0 if none.
Test 2:
1. Charge VIA computer USB or charger to 100%
2. Remove from cable, cradle etc...
3. Hold Down the Power/Standby and choose Power Off
4. Immediately boot completion open CPU Spy and Reset the Timers and close CPU Spy.
5. Place into Sleep Mode by pressing the Power/Standby Button
6. Wait 10 minutes and go into CPU Spy and note Deep Sleep time.
Again please provide the following
1. Charging Type USB to PC, Samsung Cable and Outlet Charger or Third Party Charger.
2. Deep Sleep Time 0 if none.
Now try this ;-)
Test 3:
1. Charge VIA computer USB or charger to 100%
2. Remove from cable, cradle etc...
3. Pull Battery for 1 minute and then replace and power on.
4. Immediately after boot sequence open CPU Spy and Reset the Timers and close CPU Spy.
5. Place into Sleep Mode by pressing the Power/Standby Button
6. Wait 10 minutes and go into CPU Spy and note Deep Sleep time.
Again please provide the following
1. Charging Type USB to PC, Samsung Cable and Outlet Charger or Third Party Charger.
2. Deep Sleep Time 0 if none.
It bet I know what you will find but lets see.
Ran another test today. Yesterday after doing a cold start after disconnecting from the charger I went many hours with barely a percentage point drop on the battery. Had lots of sleep time.
Today I intentionally charged from my car charger on the way to work to trigger this problem, its a USB host and not a dumb charger. Phone uptime is 2 1/2 hours and my sleep state is right where it was when I unplugged, about 9 minutes (the amount of time it was on before I plugged it into the car charger). Time at 384 is 2 hours 16 minutes.
My battery is already down to 93% with most of that time sitting in my pocket (wifi and GPS forced off) so that's about a 3% drain per hour just because it won't sleep. Over a 12 hour day that would take away a third of the battery's life!

Just put it on a wall charger for a few minutes, and unplugged, now it is sleeping.

I've basically already done all of this and provided the data above, and others have done the same and confirmed. If you use a USB charger, it will not sleep at all until you either power cycle it or plug it into a wall charger for a bit. The wall charger seems to kill whatever USB charging process is keeping it awake.
Does anyone know how to report this bug to Samsung, short of calling the generic Samsung support line?

Well I my case I haven't had the same experience AC to USB charing also causes the issue. I am searching for similarities and data. This is much more than a hung bit in the code. Before we assume it code we need to confirm there are no hardware issues such as....
Non-Samsung Cable
Third Party AC Charger
DC Charger
PC verses AC
So perhaps you have isolated for yourself if we want a manufacturer to address an issue you have to have replaceable data. So I am just trying to help facilitate that.
I have xolo q700 , and now it has been 3 month purchasing it. In normal usage it gives me 3+ days of battery life with around 95% of deep sleep It works great but due to deep sleep issue there is a battery drain of around 12-15% overnight .
This issue arises when the battery gets below 15% and I get the Low battery notification, and after that, the CPU does not go to DeepSleep anymore, it stays in the 200MHz area.
The only procedure that will stop the "fuel alert" process is by restoring or by wiping cache partition in recovery mode or removing the battery and attaching it back. After that, everything works fine until the next 15% battery notification
After the 15 % battery notification, it never goes into deep sleep and always stay awake
Charging the phone does not help. After the phone is fully charged and after I disconnect the cable, the CPU continues to stay in the 200MHz area according to cpy spy .Thus I will never get a DeepSleep again, no matter what I'm doing.
I have 4.2.1 jellybean && linux kernal version 3.4.5 . I have only 3-4 app installed including whatsapp that all and my WiFi ,GPS are always off
Does anybody has any idea what shall I do. And why is this happening so? Of course I can charge the phone before getting below 15% but this is not always possible.
I have the same problem with Prestigio PAP4500DUO but my phone stays at 1000 MHz all the time. After restarting, deep sleep works fine until battery reach 15% again.
