Has there been any resolution to the 1 - 2 second wake up lag yet? I've seen several "fixes" like reducing the resolution of the lock screen wallpaper etc but none of these work for me. I've experienced the lag on KE7 stock ROM, Cognition ROM, Villain ROM and now on Lite'ning ROM.
Not sure if I agree that it's being caused by the CPU clocking down when the phone is asleep either. When I use SetCPU to set the minimum clock speed to 1.2Ghz the wake up lag is still there.
Also the lag does not occur when the phone is plugged in and SetCPU is telling me that the phone still clocks down to 200Mhz when asleep and plugged in.
Someone must have some idea what is causing this #$%$## lag.
I use Softlocker Free for this.. Works perfect for me, a bit reduced battery life but not enough to stop me from using it..
Thanks for the reply. I tried Softlocker a while back and found the battery drain pretty heavy. Might give it another go. I was thinking there must be a permanent fix for this lag problem though. Hopefully it's just a matter of someone finding it.
I also noticed the lag on my old i9000 as soon as I updated to GB so know this is across the different samsung models on GB in addition to SGS2. I really do think its the clock going down despite your setcpu settings. Use cpuspy free from market and you will see what I mean. Once its in standby it goes into deep sleep which I believe is lower than 200? But set it to 1200 min and see if cpuspy logs it as going below that just to see
It will happen on every rom right now since they are all based on the firmware. I really think it saves battery going into that clock mode and if someone comes up with a fix the cpu will have to run at a higher clock rate and battery loss will be significantly higher

I am using Lite'ning rom 1.4 right now, when I press the home button til the screen on take around 0.5 second, is it normally?
I've tried this app,and it did seem work. I'll try to see how about the drain of power.
I was using No Lock and it didn't make any difference. What is really annoying me about this is that some users are seeing the lag and others apparently aren't. The lag on my phone is probably about 1 second. This isn't a really big deal unless this sort of thing annoys you. My iPhone didn't have the lag, my Desire didn't have the lag and I feel a high end phone like this shouldn't have the lag either.

There seems to be nearly as many combinations of symptoms as there are phones. Mine has the same 1s or so lag regardless of how I wake it up. I tried SoftLocker again. Not only does it chew the battery, it was randomly causing my phone not to wake up at all, which then required a reboot. Softlocker has since been uninstalled.
The lag definitely doesn't show itself if the phone is plugged in or if music is playing in the background. Also if the phone has only been asleep for 5 or 10 seconds the lag is generally not there.... but not always. This seems to be inconsistent.
Then there are the fortunate users who aren't seeing the lag at all..... unless of course they are failing to mention that they have something running in the background like the music player that is stopping the phone going into deep sleep.
All I know for sure is that it's a PITA that Samsung needs to address. Given that I've read it was an issue with the S, I'm not holding my breath on that one though.

Don't want to fork/derail the thread, but are you guys experiencing only the "Wake Up Lag" or also the lag when pressing the Home button while unlocked. I see some lag when using the home button to go back to Homescreen 1 for example. In case you folks are seeing lag in both the cases like me, could it be that both have the same underlying cause.
There is this other theory about the bundled Voice Talk app from Vlingo having the shortcut of Home button double tap, which causes any Home button tap to wait until the double tap window before doing its thing. I don't see that mentioned in this thread, but it kind of makes sense for the Home button lag, but perhaps not so much for the Wake lag (at least I could not think of a reason for that to happen). What do you guys think about both these problems?

Well well finally users are reporting this problem, good to see its not only me.
Anyway, I don't think the Phone goes to any underclocked frequency when it goes to sleep. Cause if you can test SetCPU by setting it to 200 MHz then you will notice that in 200 MHz the phone turns itself off, you have to turn it on manually. So the problem is related with firmware definitely. And there are no fortunate users, some users don't take this as a problem, some don't notice it and some notice but doesn't agree, but here or there everyone has the bug. I hope the issue will be fixed in future firmware upgrade.
Regards.

It may seem crazy but...
The delay depends heavily on the lock image you choose for lock screen.
With stock image it's instant, with custom background it slows down significantly.
My theory is that custom image is being resized while low Cpu frequency, it takes a while.

I've just tested that, it's the same no matter what background I use.
Wow..
Seems like the thread I can finally count on! Lots of behavior that I experience as well. I have the home button lag and the wake up lag and it's bugging me.
One thing to note.. The wake up lag is worse when you have an SD card inserted -> This scenario was the same for the SGS1 too. Anyone can confirm this?
I'm using No Lock as personal preference but the lag is always there. All behavior you guys mention (abt headphones plugged in, charging, within 5-10secs) are all being observed.
Eagerly waiting for a fix!
I had lag on my first SGS2, but it was worse that yours, at about 9-10 seconds (that's no exaggeration) plus high battery drain (Only getting about 6-7 hours battery at normal use). Went and got a new S2, no lag, and battery lasts 36 hours now.
It may not be the case with yours that its faulty, but I think I fixed the first SGS2 by flashing a newer rom, then doing hard reset and clearing cache's. I now have 2 shiny new SGS2's working as normal.

I did flash a newer ROM, but didn't do a hard reset.. all my apps were intact. Perhaps I will spend sometime on it this weekend. By the way, which ROM did you flash on your first SGS2 that fixed the problem?
Also, I tried SoftLocker and it works!! The only downside is the battery life. I loose about 4-5% per hour while I was asleep. That bring me to say that the delay is not caused by the voice input function, but rather due to the device going into deep sleep (which may be normal). But it's the waking up that's taking long.
Still seeking for more ideas...

Yes, I found that SoftLocker is not really a solution because of the battery drain and some other bugs it introduced.
Anyone who is experiencing this lag should be contacting Samsung. I contacted Samsung Australia and they told me they had not heard of the problem. If everyone who is experiencing the problem reported it to Samsung, I think there may be a far better chance of a fix. Anyone who is annoyed by this bug, please email Samsung via the link on their website. If they are flooded with complaints they "may" act and provide a fix.
So i never noticed this before rooting my phone, but ever since i have rooted it, ive been on about 20 diff roms and finally landed on CM7. when i charge my phone through USB its fine. But if i plug my phone up to my wall charger, my phone decides its going to lag like crazy... I cannot type at all, screen is very un responsive, i have to hit a letter and press down for a good second or 2. ive googled this issue up and down for days and no one has an answer that i can find. has anyone had this issue? if so what have u done to fix it? its super annoying.
If you have your CPU settings where your phone ramps down real low when the temperature is high then that could be the cause. Using your phone while its charging will make it quite toasty.
right now the CPU settings are just as they come stock on CM7 i dont know how to adjust any of that
If you wiped data/cache, performed a completely fresh install of CM7 including the stock kernel, don't have any underclocking or Profile apps (tasker, etc) that change anything on a wall-charge event, and you are still seeing the problem, my guess would be that you aren't using the factory usb-to-wall adapter or the one you have is damaged. This may not be true in your case but I know that using 3rd party chargers causes performance problems (including touchscreen lag) on some devices.
I was having this problem too up until recently. I have been experimenting with setcpu and discovered a change in settings that for me has drastically helped. Open setcpu and click on the advanced tab. Change your sampling rate to 10,000. This causes your cpu to more frequently determine what kind of load its under and ramp up/down accordingly. Next change your up threshold to something in the range of 50. This lowers the threshold at which your cpu ramps up/down. Since applying these settings I have found my phone is substantially more snappy both when plugged in and unplugged. Best of luck
Are you using a cheap, Chinese charger for the phone by any chance (AC charger)
I had a cheap one for my old blackberry...same issue.
Scrapped it and only use HTC chargers now, bought a second one to have at work.
Just throwin' it out there.
I'm stock and my phone does the same.
i had this same problem a while back and turn out it was the outlet i was using. it had a short somewhere and was sending way to much power to my phone. try it on a different outlet
Maybe it's just me, but all of my HTC phones seemed laggy when charging. Just an annoyance for texting, but it makes games just impossible. I haven't really noticed it when running CM7 roms, but I may have just gotten used to it

I make it short:
Yeah another wifi/ battery thread. But the only one with an actual solution for pi poor battery life after 21 update. Some people reported it helped also with the sod.
Wifi sucks battery dead.
Some people let all sorts of juice sucking bat-control apps running to find out that stock app reading is not lying: The bloody wifi never turns off even set to do so in the settings and just kills the battery of the device.
If this is your workaround you owe me a thanks . If you are an Asus employee testing poor battery issue give me credits in the fixing OTA by repairing the 'never' settings:
Go to
settings, w-lan,advanced (click on the three dots in the upper right corner, there it is), keep_wifi_on_during_sleep:
Instead of setting it to 'never', set it to 'only when plugged in'.
Now put your machine in sleep, wake it after 30min or even much less and BOOOOOOM! here we go:
You will see in the battery settings, that your wifi just has stopped pausing. Depending on how long ago the battery cycle has started you will see two shorter bricks instead of a long one as before. While waking your machine concentrate on the battery icon and you will notice the wifi-icon popping up just a second after you have woken the screen.
Of course this works also with shorter breaks but I'm not sure what is the shortest interval. Longer sleep period opens the gap in between two wifi-sessions wider. So this makes the working proof easier visible for the eye.
Sort of really a shame that Asus, Google and Nvidia have hybrid, wrongly programmed and even forgotten settings in their setup. (see my thread about the multitasking of the HTC1X http://forum.xda-developers.com/showthread.php?t=1599214 Maybe helps your multitasking issue.
But as we know, nobody is perfect .... except for xda!!
And then, many report, they don't have this problem at all. Very strange that not everybody is affected by this blind setting.
If this solution doesn't help your device,I am sorry for you. Maybe you have to stick to the bat-control app and learn how to read it, or RMA your device.
Did the job for me.
So I am ready for summer to join in, got enough juice for the IPS+ screen to stun the sun the whole day lun . Rock'n Roll
Edit 121002:
JellyBeans workaround as well.
Edit 120616:
Thank you Asus that the .28 firmware makes my workaround obsolet. Now get rid of this arm5 coding and let the bugger run !!
Edit 2:
Title changed from 'Asus you owe me a blowjob' to something less attractive for trolls.
Should be an obvious solution for everyone. But took me a hell of time to use the next best (second) obvious setting for my w-lan and get the battery saving.
Edit:
Please don't abuse my thread to flame, blame or mob your boss, retailer, dog or whomever. Only confirmation or non-confirmations welcome. If you find another or better or additional solution in the future or the past please feel free to post it. I did not have the time yet to check for the actual amount of powersafe but regarding my normal readings we are gaining the whole lost lot back and don't need to throttle down or ruin our eyes. I reckon the bat is gonna be better because now some of the ASUS optimisation hits some ground.
If you want me to fled off, I have stolen your ideas or you are an ASUS employee with no job-offer, don't PM me.
Thanks
I have been using this setting for a while and while I do get better battery life using the "when plugged in" setting than the newer "disconnect during sleep" setting, in general battery life is still worse in .21 than in previous builds and for me WiFi alone still accounts for more than 60% of my average battery usage according to the battery settings menu. For all of my other Android devices the screen is the largest single user of battery.
It does not happen to everyone. I have it on "never" and as soon as i click the power button, wifi turns off... if i wake the tablet right away (2 or 3 seconds later), i see the wifi reappearing and reconecting. So, for me, the wifi turns off instantly.
In the battery graph my wifi line is nonexistant whenever the tablet is sleeping.
I believe the wifi options are implemented correctly (sort of). But for some reason, it doesnt seem to work for some users.
Another way to save battery is to increase the wifi scanning interval... but that is for when you are using wifi.
I guess, for those experiencing the battery drain, it may be a good temporary workaround to use the solution mentioned by the OP.

another way to MAKE SURE you save battery is turn the darn thing off and shutdown and then when you need it's ready to go. I been doing this more recently and it defeats the purpose of tablet, but hey, when i need to use it, after the boot up its on. not trying to be funny.
Let's not get carried away. While a good suggestion it's far from a real solution for all the people that are encountering this issue. It's kind of like suggesting just turning off your tablet when your not using it to prevent battery drain.

Auto flight mode
I always install an auto flight mode program that will turn off the wifi when the screen turns off since most widgets prevents the system from turning it off and going into deep sleep.

Your way takes far too much time for me to act spontaneous. With my changed settings it's doing it automatically again, just as was intended the 'never' setting. Unless you charge the tablet by cord, the wifi turns off while you put the tablet asleep. I say settings are messed up.

to the OP, have you noticed that when you put wifi to stay on only when plugged in, when in sleep, that it takes a little while for wifi to come back online? meaning if you use the setting you said, then put the prime to sleep unplugged, then wake it back up, wifi doesn't connect back immediately. it takes a few seconds to come back online. that's the only thing I personally don't like about it.

yeah but personally this means to me it's working correctly. For the wifi to come back on instantly it would have to keep a connection and just not transfer data, when in deep sleep it completely turns off the wifi radio. When you wake it back up the radio turns back on, and it needs to connect to the AP all over again. This means the wifi was in a deep sleep (actually turned off the tab is in deep sleep) and it is working correctly.
I really wonder why every thread in this forum sooner or later becomes a trolling/flaming thread....
So guys, as usual (*sigh*) please stay on topic.
Trolling and flaming won't be tolerated but will be rewarded by other gifts like infractions and bans.
@OP: You might think about stoping posting in red: It usually implies a high rate of aggressivity towards other members.
Even if this might not be actually true in your case, other members still might missunderstand you.
On topic: This "fix" is really known since like, dunno, Froyo times? At least this setting is there already for ages.
Apart from that it should be obvious that turning off the Wifi drains less power.
However, you had good intentions so don't destroy them by flaming other members.
If you feel attacked by any post, just report it (obviously this goes for all members)
Thanks for clearing up, Diamondback,
What has been known since Froyo x.x is still worth mentioning. Many user have just started their android career because nowadays the hardware and the software are worth it. And once in a while talking about an old known tip is worthwhile especially since nobody else did.
@ demandarin ;-)
Edit on topic (referring to Diamondback):

I've been using this option since day 1. The problem is not that the wifi doesn't sleep. It's more so that it sucks way too much power when it is on.
I have an iPad2 3g as well which I received as a birthday gift so I kept it and with wifi and 3g always on, I still get 5-7 days of use.
On the Prime its dead under 2 days if always on and 3-4 days if off when asleep.
So it's most likely an optimization issue or driver issue.
Maybe the transmit power should go to low when asleep rather than staying strong.
Who knows. Regardless this can be fixed by Asus if they really look into it.

Actually the iPad has it's SW architecture on the plus side. I think the high battery drain on the TFP (and/or Android in general) is also strongly linked to the number of apps synching in background.
Maybe it can be fixed with drivers. Lowering transmit power sounds good. Could be that Asus optimized to much for the folks complaining about wifi performance....
The setting to turn off wifi while the tablet sleeps makes no sense for my use case. I mean for a wifi only device, it makes not much sense to turn it's connection to the outside off. How will I then receive notifications on gtalk, mail and so on? If I would like to safe power that way, I rather turn it completely off.
For a phone with 3g / edge data connection it might make sense. This applies for the 3g iPad as well.
I agree, it got a bit worse with .21 but for me battery life is still awesome.
Thanks anyway for bringing it to the mind of new users. Although I wouldn't call this a fix but a workaround.

My iPad2 goes ding ding ding all night. Lots of apps syncing. 3 email accounts. CNN app, and multiple other apps.
But I think iOS uses a very low power state for background sync while in sleep compared to Android.

"FAQ
Q: Wakelocks "wlan_rx_wake" wake up my device constantly what I can do about it?
A: The problem is neither Android nor the kernel, but the router and the (Windows7) network. In the network properties, uncheck "IPv6", disable the service "IP Helper", "Shell Hardware Detection" and "Windows Media Player Network Sharing Service", which provide ongoing Traffic. Then they scored again 98% of deep sleep."
And how you disable ipv6 on your phone/tablet is with a script but the value in the file gets recreated everytime you turn wifi on and off. So if you disable ipv6 then turn wifi off, then back on, ipv6 will be enabled again. I got around this by a tasker profile that will run every time my tablet connects to a wifi network. So it disables ipv6 right away again. You could do this in an init.d script(or in sysctl) as well but then you have the issue of it resetting itself if you turn wifi off/on
If you have tasker create a new profile for when wifi is connected, then run a shell script task, and check run as root. This is the command echo 1 > /proc/sys/net/ipv6/conf/wlan0/disable_ipv6
to enable it just replace the 1 with a 0. You can also run the command in a terminal window if you just want to test it. I did it for my phone, and I just set it for my prime so I'll see if it drains less battery with it off..

Yes, I agree about the drain but isn't it probably because of the stylish casing! So nothing we can change there, but Asus could clock it down while asleep as you suggest.
You are right I have already changed the op from fix to workaround.

I would just like to say thanks and let you know that I had SOD problems on my prime (as bad as up to once every day in frequency) for a very long time since .21 came out, after trying your work around (several weeks ago) ever since I have not had a single SOD sleep of death issue whatsoever.
I always suspected it was dock recharging causing the SOD fault but maybe it was a bum wifi stack or something, so thank you very much my tab is much more stable because the suggestion you've shared with me.
Unfortunately it does not help any flickering or GPU bugs I tend to get on occasion. I truly hate .21 it is so god awful for GPU, SOD and storage I/O.
I should just man up and downgrade but meh, sif i have the time do it
But yeah, thanks heaps, your workaround is an awesome suggestion.
My wife's Rezound (.605, ClearnROM 4.5) has been stable for weeks and weeks. Then, in the last 72 hours or so, it suddenly started ripping through its battery in minutes -- fully charged to dead in 90-180 minutes, even if the phone is just sitting on a desk, untouched, screen off. There doesn't appear to be anything running in the background to account for the drain (no Facebook or anything like that).
Any ideas? Really don't want to have to return it to stock, exchange it with VZW as defective, go through setting up a new one.
Thanks in advance...
a silly question but have you tried to over clock or under volt it recently?

best thing to do is go into settings and see what has been using the phone. Go into apps, too and see what has been running.. Finally, an app like better battery stats can really help you see what is killing it.
Often in cases like yours, its a recently updated app that is keeping the phone awake for some reason.

No to overclocking or undervolting. Haven't really had the need to do either since moving off our Droid Xs some months ago. But that was a good thought.
The screen appears to be what's killing the phone. For some reason, it keeps setting itself for Sleep/Never, meaning the screen is on all the time. The last time spent changing that setting seems to be working. Not sure why it keeps toggling back to that setting. May have to reset the phone, reload a ROM and see if a fresh start makes a difference...
Today I noticed that although I have my wifi turned off, from time to time throughout the day it randomly turns on without me doing anything. Has anyone else experienced this? I'm thinking it may be some app or another turning it on, but I'm at work right now and don't really have time to troubleshoot it.

I too have noticed this. Here's a question that may blow away my theory - Do you use AT&T Smart WiFi?

Indeed I was using AT&T Smart WiFi. I just turned it off. We'll see if that seems to make any difference.
I use the dumb wifi (i set it on or off as I need to... need NFC tags now) and no problem what so ever.
Ok, so I stopped using Smart WiFi. I have not seen the wifi turn on randomly since.
Bet your battery life improved along the way...
Yeah, battery life has been improved. Although it's still not great. I'm waiting for a custom ROM to fix it, but Android OS uses like 54% of my battery. Pretty sure that's more than it should.
