[Q] TF101 Prime 1.9 Wifi Sleep

Since I don't have permission to post in development forums, I will have to ask here. Just NVFlashed to Prime 1.4 then upgraded to 1.9 and everything works great except now I notice that the Wifi to shutoff when screen is off does not appear to work. I know this was working in the stock ROM. Is this a known issue or something particular with mine?

Was about to ask the same question. Happening to me as well. I notice my tfiner goes into deep sleep and still the wifi is on. I have to turn off with the screen.

I have the same problem and I have checked the sleep policy multiple times. I have even changed it to never turn off then back to off when the screen turns off then proceeded to reboot the device. I still have the issue though.

Yep, seems i am getting this same issue seems wifi is on all of the time.

Yep last night the battery in kb went from 65 - 3% in 10 hours while in sleep. Says 43% of battery use is wifi. I did read somewhere that it was said to be the latest google maps update causing it but I uninstalled those and it still does it. It does appear to be going on and off like some other people have describe. I am pining it from desktop and every other time it starts with 3500 ms ping time then the last 3 are normal.

And Today I fully charged both KB and Tablet then turned on airplane mode and left in standby all day. Its 8hrs of uptime and only 4% battery drop between both. Not a deal breaker or anything just want to let someone know before 2.0 comes out to see if maybe theirs an easy fix. I will ty to run fix permission in CWR and recheck.

[Q] No Deep Sleep on CPUSPY

Hi
I wonder if someone can help me.
After the recent firmware update cpuspy was showing that my Transformer would go into Deep Sleep for 90%+. Was obviously happy with that
I got prompted that 12 of my apps had updates so updated them. Thought that would be OK as I was having no problems with them at that point.
However, it never goes into deep sleep now and the lowest it goes is 216MHz. The battery drain when I'm not using it is therefore greater. 2% overnight on standby is now 15%. Not OK
I had taken a back up using App Backup so thought I would use the (only) one I had before the recent updates. The problem is that I have not restored before and have forgotten the password I used. :Muppet: Anyone got any ideas how I can roll back the recent updates and try them one by one to find the culprit. Or any other solutions of course.
Thanks in advance
Alex

I had a fully charged Transformer and dock this afternoon and now the dock is dead and the tablet is at 3%. So I saw this thread and downloaded CPUSPY and what do you know, 60% of the time it's at 216mhz, 23% it's running at 1500mhz and deep sleep is only 11%.
Anyone know how to fix this? My dock is a B70 model and pressing keys while putting it on standby doesn't wake it up so I don't think this is a dock battery drain issue is it?
BTW: Running Prime 2.1.1 and roach2010 kernel.
Viffer, does your touchpad wake your tablet? Mine does. The keyboard doesnt but the touchpad does and it may be related to why it won't go into deep sleep.

Is your Sensation Deep-Sleeping?

Why do you ask?
I’ve used a few different ROMs where the device fails to enter deep sleep.
What difference does it make?
It’ll hurt your battery life.
Can I replicate?
Yes, charge your phone until the led turns green. Remove the power supply.
This prevents my device from deep-sleeping a lot of the time. It can only be resolved by rebooting. The active wakelocks are DATA5 and DS
How do I check?
In the terminal type
Code:
toolbox uptime
You should get an output such as this
Code:
up time: 08:33:26, idle time: 06:32:08, sleep time: 03:04:56
Alternatively, if you are a Tasker user, you can use the deep-sleep-detective profiles to give you real time sleep stats between each screen on/off state – A 7-day free trial of Tasker is available here.
Alternatively, install system tuner from this thread. In the CPU tab, the sleep time is detailed.
How do I monitor?
After a period where your screen has been off, make sure the sleep-time has increased proportionally.
What is supposed to stop the device from sleeping when the display is off?
Media playing
Charging
Active call
What do I do if I have the same issue?
Please post your ROM and Kernel and we'll go from there...

This doesn't happen on CM7.

Are you saying that because you've had it happen on other ROMs, or because you currently monitor it?

CM7 a10 here and I have sleep issues when Bluetooth is on (paired on not).
I have tried various faux and bricked kernels.

Just tried overnight from a full charge and I lost 3% in about 10 hours standby.
Never saw the issue before.

Thanks - deep sleep detective or an app called better battery stats will identify the problem wakelock. If you track it down, please post it.

Thanks, keep an eye on your sleep stats next time, as it doesn't happen every time for me.

I have the same issue too on ARHD 3.6.7.
Wondering how many users out there experience the same thing.

Checked on my CM7 / Faux123 config, no issues here.

My Sensation seems to go into "deep freeze" instead of deep sleep. Tested on both ARHD 4.1.8 and Hypersensation 1.2F. After the device has been idle for a while it's not possible to wake it up. No reaction to hardware buttons whatsoever, even if the charger is plugged in the LED won't turn on. Pull out the battery - and it boots fine.

That's a different issue and unfortunately not something you can solve with the methods in this thread. It has happened to me before and if volume up and down and power button held all together didn't reboot then it was a battery pull for me too. I can only suggest you check and maybe increase your display off cpu settings.

Thanks for your suggestions brandall. I have been able to track down the cause of the issues. Turns out, the radio that I flashed recently (the 11.59.xx version from this thread: http://forum.xda-developers.com/showthread.php?t=1178143) was the cause. Rolled back to 10.58 branch and all is good.
Checked if the phone is deep sleeping using your methodology and turns out it is. Battery life is still not great though, but whatever, I guess. :]
Cheers.

Thanks for sharing - I must admit I've haven't tested different radios... Thinking about it now, I probably should have done! I must have too much faith in 'because they are stock they can't be broken'... I am already using 10.58, but no harm in testing others to see if this is the cause for me...

P6210 - Huge Battery Drain on ICS

Anyone experiencing battery drain on ICS? I upgraded, rooted, and removed some of the bloatware to help. Thought it was fixed but my tab is dead again. Says the Android OS is taking up my juice. Was never a problem before. Could leave it on standby for days with HC. Now its dead in a day or less.

I initially saw similar behavior, but once I killed the cached processes once, and since have shut down to charge and started new, I haven't seen that behavior.
Do you have WiFi on? Could it be you have apps that are checking to be updated? I know in the past on my phone my Amazon Appstore has a habit of starting itself up and continually checking for updates for itself and for any apps I got from Amazon.

Tried it both ways...wifi on and off.

Try using CPU spy (free in market) or betterbatterystats (free- search for it here on XDA) to see what is eating up your battery exactly.

I noticed that I had a conflict between "Power Savings" settings and the "Display" settings. Putting them both at 1 minute resulted in an always on screen I had to disable the Power Savings to correct the problem.

I did have something odd happen yesterday that seems to have kept my screen on for 4 hours. When I got home and opened my case the tab was very warm, and shut off. And all but entirely out of power, before that it has used about 10 % in 17 hours of standby with about an hour of use, or so.
I think it is possible that an app that previously didn't keep the screen on is now for some reason keeping it on, and I didn't notice when I closed the leather cover.
No issues today, but I am going to try and see if I can find some release notes to tell me about the new download for ICS for the P6210, perhaps this is addressed?

Just to update I installed the betterbatterystats. I showed a couple of things that were keeping my tab awake. Once I fixed those I thought that would be it but it was still draining. I then installed juice defender and had it turn wifi off every time I turned the screen off. That did it. Was never like this before the update but at least its good to know I fixed it.

i suggest checking better battery stats for AudioOut_1 Partial Wakelock. its been draining my phone fast when i upgraded to ICS.
check it here: http://forum.xda-developers.com/showthread.php?t=1629346
now my battery is working great.. i just left my tab for 10 hrs in the locker when i got the tab its still have 97% battery.

for me i just checked and changed my wifi sleep policy from never to when screen turns off and its fine now. :highfive:

I thought about this very issue; I decided to wait.

Did you download the ICS as opensource? Myself, I am deciding to wait for the OFFICIAL verson to be released.

I had the same problem. i even went back to HC to make sure
the issue is not there (it wasn't) and upgraded to ICS
again (full wipe all the time). No luck something keeps
my device unable to go to deep sleep.
Now i'm back at HC again

The version is OFFICIAL .
It's just available only for some countries.

i had the huge battery drain issue while in stock ICS..
the tablet simply refused point blank to go into deep sleep.. in HC it would but not in ICS.. i would take the tablet fully charged to work and not use it much there.. by the time i was travelling back it would be 60% drained in not using it througout the day...
recently flashed to aorths CM9 build and all my battery woes are gone.. now when i get back from work the battery is at 96%!!
battery drain during usage is the same but the CM9 build has awesome battery conservation stuffs for when you dont use it..
would suggest everyone who has these battery issues to move to CM9.. really helped for me.

My battery usage on CM9..

Early results show Juice Defender is helping a lot with mine too. Thanks for the tip!
Next morning: Just the free version of Juice Defender using the default profile took me from 35% overnight drain yesterday down to 3% overnight drain today. That's not bad. It should be even better tomorrow because I've turned off all location services after seeing that BetterBatteryStats says Google location is the worst single offender at keeping wifi going overnight.

Could you tell me how you "killed cached processes" please?
I am having similar battery drain. I am in the process of completely charging battery after it drained 40% in sleep mode last night, wifi off in sleep mods, notifications off, sync off.
I have already done a reset to factory, tried draining battery, and recharged in off position.
Nothing is helping so far. I have installed better battery stats, and CPU spy this morning, and will have data tomorrow morning.
thanks for any help

I had the same exact problem ever since the stock ICS update. My Tab Plus is all stock, no mods at all. The battery would completely drain after one day, and I have very little on the Tab Plus. Nothing helped at all, so I finally bit and did a factory wipe. The battery drain stopped immediately, so I started changing the settings back to the way I like it.
Then, next day the battery went completely dead again! I back tracked and figured out exactly what it is which makes absolutely NO SENSE - turning off wifi in sleep was what was draining the battery! See my screen captures. Notice on the first screen shot, as soon as the wifi stays on the battery drop bar stayed almost flat.
I observed a similar behavior on my 100% stock AT&T GS3 phone also, turning wifi off during sleep causes more battery drain.

I'm getting "suspend backoff" under kernel wakelocks which is preventing my tab going to deep sleep when unused. Everytime I wakeup in the morning my tab is dead. The only solution I found was to turn off wifi if I'm not using it. Anyway fixing this?

Juice Defender. The free version of the app, using the default profile, should take care of this.

Problem with my nexus 5

Hi guys, last night I flashed elemental x .38 kernel paired with my slimkat weekly 4.6 build and a weird problem occurred...
so i went to bed with 93% battery left and I woke up with 82% (i never had deep sleep issues before with any kernel) and then when i turned on my phone, it was EXTREMELY laggy... I thought i was a kernel setting, it was not... I reflashed the kernel and tried franco, and used stock slimkat and they were ALL laggy. I don't know why as to it is laggy since it has never been for my phone, I didn't do any tweaks overnight and the kernels are all pretty much stock settings.
Can anyone help!?

Use this app
http://goo.gl/Ba3W4M
Observe it for few days
Looking at what is causing battery drainage
Just make sure that NFC, Background wifi scanning, Auto syc, bluetooth, wifi, data are off when not needed
If there is no result, post that app screen shot here

I think I found the error. Only my Nova launcher was lagging so I thought my whole phone was lagging while scrolling..
However the battery is still draining quite quickly than normal...I'll take a look for a few days with this app.
