[Galaxy S II Q&A, Help & Troubleshooting] khawarspirit:
I believe it's the overall latency that's bad on these Exynos boards... I was surprised how instantly the HTC Rhyme woke :o

The i9100G has an OMAP processor, yes? Can someone confirm if it has less wake time than the i9100?
[Galaxy S II Q&A, Help & Troubleshooting] ArcticWolf91:
I just switched to this phone from the T-Mobile US GS2 (different processor), and I can confirm that this phone does have a longer wake up time. The T-Mo GS2 was very fast. It'd be awesome if someone can figure out what's causing this.
[Galaxy S II Q&A, Help & Troubleshooting] -Loom-:
The wake-up lag was the first thing I noticed with the SGS2.

I was using the SGS1 before, also with AOKP rom. And there was absolutely no wake-up lag. The phone was on *instantly*, even when coming from deep-sleep.

So Samsung must have designed something seriously wrong here.

But I doubt this will ever get fixed. Not after a year since the release.
[Galaxy S II Q&A, Help & Troubleshooting] IonutP:
Some say that the lag was fixed in the newest versions of RR and NeatRom roms. Others,like me,still have the lag.
[Galaxy S II Q&A, Help & Troubleshooting] -Loom-:
I doubt that. Maybe the just had constant wake-locks running.

I tried nearly all AOKP roms and some stock ones so far, and the wakeup-lag has *never* changed. No matter what.

[Galaxy S II Q&A, Help & Troubleshooting] aydc:
Today, I discovered that AOSP/AOKP ROMs or custom kernels or both have much worse wake up lag compared to stock. I returned to completely stock rom and stock kernel today after a long time, and to my surprise, my wake up lag dropped from around 1.500 ms to 900 ms or so.

So, I don't know if it's the ROM or the kernel or both, but all stock is much better than custom in terms of wake up lag.
[Galaxy S II Q&A, Help & Troubleshooting] minidou-77:
We're almost sure that it's kernel related

Probably Sammy made good changes about this so wait for the next update of kernel sources ;-)
[Galaxy S II Q&A, Help & Troubleshooting] ArcticWolf91:
You know what I just noticed? If the charging cable is plugged in, it wakes up instantly. This is definitely software related.
[Galaxy S II Q&A, Help & Troubleshooting] -Loom-:
The phone is not in deep-sleep while charging.

You could also install some apps that produce a contant wakelock, and the phone will be there instantly. Of course with greatly reduced battery.
[Galaxy S II Q&A, Help & Troubleshooting] matabillions:
No, I tried stock (completely stock) because of the wakeup lag and it was just as bad. Maybe 1500ms instead of 2000ms, but that's not an improvement to me.

Watch this @1:03... no wakeup lag on the SIII with CM9!
[Galaxy S II Q&A, Help & Troubleshooting] aydc:
Maybe the phone wasn't sleeping there.

Watch this video, at 24:40, the reviewer complains about wake up lag on SIII and shows it's just as bad, if not worse than, SII.

http://www.youtube.com/watch?v=tV1tVHrMRN0
[Galaxy S II Q&A, Help & Troubleshooting] matabillions:
I know, but that's with the stock ROM.

My point was that maybe CM9 fixes the issue on the SIII.

One can hope at least... but yes, maybe it just wasn't sleeping.
[Galaxy S II Q&A, Help & Troubleshooting] dzoni_ml:
I got back from ICS to stock GB 2.34 and lag dissapiered! compared with my gf's one witch is all stock and it used to be big difference when i was on ics but now is same. half seconds delay maybe.And it looks like it going less in deep sleep so most of time it wakes up instantly.

So just go back to stock gb,i dont see reason for going to ics,its a not win at all to me.Same ui,just more bugs,and all is smootrher on gb.Talking about official ones
[Galaxy S II Q&A, Help & Troubleshooting] plotinus:
I was on ICS but indeed the lag make me crazy. One time my gf pressed the home button and my phone lasted too much to wake up so she pressed like 3 times... She just looked at me and said hey why is it taking so much? In that moment I realized about the lag and could live with it. Try aokp/aosp and stock but I just when back to gingerbread. Like it's been said. ICS is a no go for me too...

My advise is to get back to gb. Less lag!

Btw I can't believe the wake up lag on the s3! What a disappointment!! I even once thought. I'm gonna buy the s3. I'm sure it won't have any wake up lag... Guess I was wrong!

[Galaxy S II Q&A, Help & Troubleshooting] IonutP:
What stock version are you using?
[Galaxy S II Q&A, Help & Troubleshooting] Pfeffernuss:
Doesn't matter as it's not true. You will have wake-up lag on every Rom, with every kernel, whatever you do. Unless you want to constantly invoke wake-locks or keep the phone on a charger, that way the lag will be gone.

Don't believe all these useless tips/remarks/advice. Wake-up lag will be there, period.
[Galaxy S II Q&A, Help & Troubleshooting] matabillions:
That's ot entirely true. The wakeup lag is significantly less on GB to the point where some users may find it not disturbing at all.

Yes, it's there on every ROM, but ICS has made it particularly awful.
[Galaxy S II Q&A, Help & Troubleshooting] MarekD:
I was testing ROMs for past week. A lot of them in all possible streams: AOKP, AOSP, Stock and MIUI. Conclusions: all ICS based have serious wakeup lag. All GB based have less disturbing lag. GB based MIUI seems to be the most responsive one. One more build I need to check is CM9 nightly… will try it today evening.

I'm curious about your result with CM9 nightly... although I'm afraid I already know the outcome :(
[Galaxy S II Q&A, Help & Troubleshooting] IonutP:
The lag is there too.
[Galaxy S II Q&A, Help & Troubleshooting] MarekD:
Surprise, surprise! I’ve only tested it for an hour or so but no matter how many times I’ve rebooted it or for how long it stayed undisturbed there was no wakeup lag at all! I can only assume that there had to be some background process that was causing constant “awake” state. I would give it some more time but this rom is so basic that there is even no possibility of adding google account or a file manager to manually install applications. I will look for some customized versions of CM9 or try to tweak it myself later.

Edit: and one more thing: this latest CM9 is stupendously fast! It beats all GB rom’s I’ve ever tested!

Edit2: I found gaps update for CM9 so will give it a go again today.

Could you post link to the cm9 you're trying? I tried once but bootloop hehe or pm me the links please!

-Don't smash your face... Let somebody else do that for you"
[Galaxy S II Q&A, Help & Troubleshooting] aydc:
CM9 versions, when first installed, go through a long mediascanner process, if you have many mp3s. That's why after first install for some time you will get no wake up lag. However, after a while it returns, and it's worse than stock.
[Galaxy S II Q&A, Help & Troubleshooting] matabillions:
You can check whether your phone goes to deep sleep with CPU Spy (for example... or Better Battery Stats).
[Galaxy S II Q&A, Help & Troubleshooting] MarekD:
True. I have just came back from complete CM9 installation and lag is still there. I think there is no hope for us other than switch vendor for HTC or, God forbid, Apple... Nah, I'll stick to galaxy :-)
[Galaxy S II Q&A, Help & Troubleshooting] matabillions:
Nah, Apple makes for many more problems... HTC phones are the best but I hate PenTile and the X is too big... maybe get a Sony Xperia P when it receives ICS...

...or maybe someone solves the wakeup lag...
[Galaxy S II Q&A, Help & Troubleshooting] ArcticWolf91:

Strangely, my ThinkPad tablet also has a huge wakeup lag since the ICS update... mybe it's more than just hardware?

Do you guys still have wake up lag with Wake Lock?
[Galaxy S II Q&A, Help & Troubleshooting] MarekD:
No. With Wake Lock lag is gone. But in my case (VK ROM v5.1.2) battery drain is ~10% per hour
[Galaxy S II Q&A, Help & Troubleshooting] IonutP:

[Galaxy S II Q&A, Help & Troubleshooting] xmfpdlemalnz@hotmail.com:
With power wake lock, battery drain about 1.5 per hour which is normally what I get without wake lock anyways.

Think it's worth it.

I love it when the screen just turns on immediately. Feels like a entirely new phone
[Galaxy S II Q&A, Help & Troubleshooting] plotinus:
gonna try wake up app to see how it goes! reporting here later

EDIT* not so good,, from 40% to 36% in less than an hour (from 4:30pm to 5:12pm) without using the cellphone (not even a message!).
[Galaxy S II Q&A, Help & Troubleshooting] matabillions:
Yes that's not a solution.

Too bad none of the developers seem to care... without wakeup lag, the SII would feel like a whole new phone!

[Galaxy S II Q&A, Help & Troubleshooting] Pfeffernuss:
It can't be improved to be less than 650ms. If that's "instant", which for some people it is as the have "no lag", than that's it.

Below 650ms will never, repeat NEVER, be possible.

People who claim to have "no lag" have a lag of minimal 0.6 seconds. Gingerbread, ICS, kernel X or Y, all irrelevant. No lag, without inducing unwanted wakelocks, is impossible,
[Galaxy S II Q&A, Help & Troubleshooting] ArcticWolf91:
650ms would be nice. I am averaging about 1250ms...
[Galaxy S II Q&A, Help & Troubleshooting] IonutP:
And how can you make it 650ms?
[Galaxy S II Q&A, Help & Troubleshooting] matabillions:
You didn't say anything new. It is well known at this point that 650ms is the minimum.

We all know that the people who claim they have no lag just have a wakelock.

From 2s to 650ms is a HUGE improvement however and there is nothing that says it's impossible.

So, no, so far it has not been shown that it is impossible and no, I don't think devs care enough. It has simply not been tried hard enough.
[Galaxy S II Q&A, Help & Troubleshooting] Pfeffernuss:
My phone wakes up within a second with every Rom-version, every kernel, whatsoever. Without wake-locks. Don't see the problem anyway.

Stating that devs don't care is utter nonsense.
[Galaxy S II Q&A, Help & Troubleshooting] matabillions:
If you are on ICS then your phone does definitely not wake up within a second. If it does, then it is wakelocked.

Stop telling nonsnse, we've discussed the facts and details more than enough.

The only thing that we haven't discussed is a solution, becuse apparently devs don't care.

So, please, if you have nothing to contribute but nonsens, just leave. Cause you still don' know the facts and I bet you have no clue about what devs do.

Guys i just noticed wierd thing.my battery went down on 5% and phone put brightness to minimum etc but also lag is gone! Not even it have but little its absolutely zero lag.like when its on charger for example.So does anyine know whats happening with phone when battery is low that also couse lag to dissapier?
[Galaxy S II Q&A, Help & Troubleshooting] Pfeffernuss:
Yesterday got my SGS2 back, the USB port was broken and was fixed. They also flashed the phone as a "service". Got it back with Gingerbread. Of course tried the wake-up lag. It was there, naturally. It was around a second, if I were to guess.

Immediately put ICS back on. Tried the wake-up lag. It was there, naturally. And it was just as long as with GB. Not longer. The same.

So now what, do I have a magical setup? For me the wake-up lag using GB and ICS is exactly the same. Not zero, not 2 seconds, it's just there.

By approximation I would say it's around a second but am not using a stopwatch. Could also be 0.8 seconds, don't know, don't care. It there, live with it.

Approaching 99% now I guess?
[Galaxy S II Q&A, Help & Troubleshooting] solarfusion:
My workaround for this is to prevent the deep sleep via using Tasker and the Secure Settings plugin to keep the CPU awake for a while after you switch the screen off, essentially delaying the deep sleep.

Here's the setup in Tasker:

Profile:

Event: Display Off

(Optional) State: Wifi connected

Task: Plugin > Secure Settings > Configuration: Wake Device - Wake Type: CPU Awake Only, Duration: 15 minutes

You can set the duration to whatever you like and I'm using the "Wifi connected" context so that it doesn't happen on 3G when I'm out and about and generally want better battery life.

Still annoying that the phone has the lock screen / wake lag. A colleague's Galaxy Nexus does not have the lag even though the battery statistics show it's been in deep sleep. Both devices run pure ICS (no TouchWiz)

Obviously delaying the deep sleep is still going to consume more battery than if the phone is in deep sleep but I find it remove the lock screen lag when I'm using my phone on and off.
[Galaxy S II Q&A, Help & Troubleshooting] Visentinel:
The devs aren't doing anything because its a hardware problem, what do you want!? The devs to release a patch that changes the DNA of your organic phone technology to slowly grow a solution within your handset? Yes this statement is as stupid as thinking it can be fixed in the first place.

It is amazing people don't just buy that nice cheap and well fitting official extended battery and put a wake lock on. Sigh...

Before SGS2 i had Galaxy R (i9103), Tegra2, GB - wake up lag (+on incoming calls) even worse than on SGS2. My old HTC Legend - no wake up lag at all (well...little on incoming calls ;)), Incredible S - no lag at all. Even if I consider my sammies much better/reliable handsets than those from HTC, there must be clearly some design shortcoming.
