[Galaxy S II Q&A, Help & Troubleshooting] qasdfdsaq:
Wake locks never reduced the battery life on my S2 much anyway, but that's beside the point.

Course wake-up lag will never be gone, but what do you define as "instant"? All of the phones people have said so far wake up "instantly" do not wake up instantly.

Every other phone on the market has some form of wake up lag. Nothing wakes up instantly, even while on charger or with a wake lock. They just wake up faster, some more so than others.

The real question is can we get wake lag down to a level people find it acceptable. That's what's being asked for in a "fix". And of course your idea of "instant" may be different to someone else's. Case in point, some people say in this thread the HOX wakes instantly. It does not. Not in my opinion anyway, but instant in my book is zero planck times and nothing wakes instantly.

Other phones also have wake-up lag. People just seem to care or notice less. My S3 incidentally wakes up twice as fast as my S2 so I disagree that it's "even worse". Though the S3 does also have lag even when connected to charger, or on a phone call, yet with a permanent wake-lock I still manage 5 days standby on the S3.

Plenty can be done about it. Just because 650ms doesn't meet your idea of instant, doesn't mean other people won't be satisfied with it.

Solved! Wake up lag on Galaxy S2!

I browsed for a solution to the problem of wake up lag on Galaxy S2 for a very long time. I did not want to root the phone or use any Custom ROM. I had realized that the problem is due to the CPU sleeping to conserve the phone's battery. I therefore searched for an app that would keep the CPU awake without draining the battery. Found many apps and tried them for a few days. I think WakeLock is the best app for the purpose. The app resolved the wake up lag and did not drain battery in almost 2 weeks of testing. It gives four options to keep the CPU awake, along with or without the screen turned on. I used the option in which it only keeps the CPU on. This app has solved my problem permanently. I hope it helps others facing the same issue.

I'm running ICS on my S2 with the Touchwiz UI.
[Galaxy S II Q&A, Help & Troubleshooting] Pfeffernuss:
The S3 wakes up in at least 1000ms, so yes, that's slower than an S2. Your S2 must have been set-up improperly.

Not going below 650ms. Unless you want to invoke battery draining wake-locks . keeping it on the charger all the time.

I never said it was instant. Other people say their phones wakes up immediately. Which is impossible, when it's in deep-sleep. Don't assume things please.
[Galaxy S II Q&A, Help & Troubleshooting] qasdfdsaq:
Stock ICS. Which others have said many times makes it a lot worse.

I never said it could go below 650ms. Don't assume things please, especially when I've said the exact opposite.

Instant. Immediate. Same thing. See dictionary.com. Again you seem to be assuming the exact opposite of what I actually said. Immediate, instant, both remains impossible in any state.

Like I said, your idea of instant clearly isn't the same as everyone else's idea but that does not mean everyone else's opinion is wrong. If some people consider the 850ms it takes the HTC One X to wake up to be "Instant" then 650ms will more than be "fixed" for them, and certainly beats the crappy 2500ms you sometimes get on stock ICS.
[Galaxy S II Q&A, Help & Troubleshooting] Wirelessgirl:
I have the I9100M from Virgin Mobile, upgraded to ICS and it suffers from this lag. I have the Rogers S3 i747M and it does not lag like the video above. The power button and the wake up button, it turns on almost instantly. The Rogers version has the Snapdragon S4 chipset like the US version. So I'm beginning to wonder if this is an Exynos issue.

Forgot to mention, I'm running stock ROM on both devices.
[Galaxy S II Q&A, Help & Troubleshooting] Pfeffernuss:
MY PHONE doesn't wake up instantly/immediately. Never claimed that. Other people do. Which is literally impossible, without having it on the charger/inducing constant wakelocks.

In this thread there are numerous people claiming not having any wake-up lag. That's my issue. All BS.
[Galaxy S II Q&A, Help & Troubleshooting] pulser_g2:
It is an Exynos SoC issue. That's it :) No solution, it's the hardware of the SoC solution that does it.
[Galaxy S II Q&A, Help & Troubleshooting] Eudoxin:
Possible solution....

Recently I switched from Wildfire to Galaxy S2 and I immediately noticed the fu***n LAG! Even Wildfire had 10 times faster wake up time.

I tried WakeLock but noticed higher battery drain and I didn't use it.

Few days ago, I thought maybe I could save some battery by underclocking with MichaelHuang SETCPU (I bought for Wildfire).

I just left all default settings and put max freqv. to 1000MHz and wake-up lag WAS GONE!

So, in setcpu I have:

1000max200min

governor on demand

scheduler cfq

I didn't set profiles nor anything else.

Didn't notice higher battery drain, but using it for just 4-5days.

It also works fine with default freqv. 1200/200MHz.

I have stock ICS (4.0.3 IML74K.BULPD) rooted with Chainfire SuperSU Pro.

Regards.

p.s. this is my first post here and I hope it will be useful. :)
[Galaxy S II Q&A, Help & Troubleshooting] minidou-77:
Sorry Eudoxin but you must have an app running in background which keeps your phone awake with a wakelock.

Install CPU spy from play store and look if you phone goes into deep sleep
[Galaxy S II Q&A, Help & Troubleshooting] Eudoxin:
Hello!

Yes, setcpu is installed from Google Play store. Nothing else changed. Before installation I had lag, and after the lag is gone.

Can you please tell me, what is the other way to check if cpu goes to sleeeeep deeeep?

Is it setcpu itself that prevents deep sleep?

Thx!
[Galaxy S II Q&A, Help & Troubleshooting] minidou-77:
No I mean "CPU spy" it is an app different from Set Cpu
[Galaxy S II Q&A, Help & Troubleshooting] Eudoxin:
Sorry, I misread. I installed cpu spy now and it says that phone doesnt go to deep sleep. Also Better Battery Stats says the same. Does it mean that the battery drain is more than necessary?

I freezed setcpu app and phone went to sleep. So, setcpu prevented phone to enter deep sleep.

Than I uninstalled the setcpu but there is still no lag and phone still doesnt go to sleep. ****. What now. I cannot disable that "wake lock" from setcpu.

Any suggestions?

Regards.
[Galaxy S II Q&A, Help & Troubleshooting] minidou-77:
Try to desinstall "Wakelock" app
[Galaxy S II Q&A, Help & Troubleshooting] Eudoxin:
I did it. And reboot. But no success. :(
[Galaxy S II Q&A, Help & Troubleshooting] minidou-77:
Install Better Battery stats (free on xda) and look at partial wakelock
[Galaxy S II Q&A, Help & Troubleshooting] Eudoxin:
Hmmm, I did, but honestly, there was a trilion entries and I just restored my nandroid backup from the begining of my phone's life. :)

It was easier.

So, SetCPU didn't alow deep sleep, whitch probably led to a higher batery drain.... Pity....

Thanks for help!

Guys im on jellybeam and i noticed the lag decreased very much...definitely less lag than cm9. And phone its deep sleeping very well. its not inatant but i fell it very similar to gb
[Galaxy S II Q&A, Help & Troubleshooting] kewinh95:
sometimes it works !

sometimes when i wakeup my phone it kind of shows a darkgreyblackscreen and it has a bit of stripes kind of xD...

i dont know why that is but some roms doesnt have that issue for me.

any one know anytihng about this ?

I think that the wake up lag problem is from the kernel , so try diferent kernels and diferent settings
[Galaxy S II Q&A, Help & Troubleshooting] :
No offense but I assume you haven't read the whole thread.
[Galaxy S II Q&A, Help & Troubleshooting] trikpa:
great stuff, if I knew about this "feature" I would never buy this crap :D

so, in a nut shell, if you don't have a wake up lag feature, your battery is draining :D:D
[Galaxy S II Q&A, Help & Troubleshooting] abmicyau:
I know this is old, but my phone wakes up almost instantly when my BLN lights are on.. and BLN doesn't drain my battery

Is there a way to take advantage of this?
[Galaxy S II Q&A, Help & Troubleshooting] minidou-77:
As always BLN -> wakelock

Wakelock -> instant wake up BUT higher battery drain that deep sleep

If you want to keep a Wakelock use the app with the same name from play store
[Galaxy S II Q&A, Help & Troubleshooting] lockex:
My phone sometimes takes 5 minutes to wake up, it's a hardware problem I think. Getting wakelock apps from the Market doesn't help either. Can anyone help? My warranty is gone. :(
[Galaxy S II Q&A, Help & Troubleshooting] beston94:
Are you running stock or custom?
[Galaxy S II Q&A, Help & Troubleshooting] matabillions:
No, that is wrong. The Exynos SoC causes only 650ms of lag. The wakeup lag with ICS is much longer (1-2s), which is a combination of the 650ms Exynos lag and a software issue.

The software issue is not present in Gingerbread and it goes away with Jellybean.

Unfortunately noobs like Pfeffernuss are incapable of differentiating between the 650ms hardware issue and the wakeup lag software issue caused by ICS. The latter is the subject of this thread.

I would have liked you devs to address this software issue, but luckily, it goes away with Jellybean anyway. Jellybean reduces the lag to the 650ms Exynos lag we had with Gingerbread.
[Galaxy S II Q&A, Help & Troubleshooting] :
My friend.

First of all this thread was created long time before ICS was even released. So no "wake up lag software issue caused by ICS" is definitely NOT the topic of this thread.

Another thing...I would recommend you to change your attitude. Before you call anybody you disagree with a noob, please tell us about your contribution and achievements that make you feel like an expert in this matter.
[Galaxy S II Q&A, Help & Troubleshooting] matabillions:
I don't need to change my attitude at all, because it has been explained to these people a hundred times that there is a difference between the 650ms Exynos hardware issue and the software issue that comes from ICS.

Yet, they keep posting BS over and over - without their stupid posts causing confusion, we could tell smart people like Pulser_g2 that there are two problems (hardware and software) and mybe they could help fix the software part. But no wonder devs can't care about the real issues, with these noobs confusing them all the time (because they are incapable of understanding it).

Anyway, JB luckily has fixed the issue. Now the lag is 650ms again, not 1000-2000ms (which was the real problem in ICS).
[Galaxy S II Q&A, Help & Troubleshooting] :
Oh come on my friend, it hasn't been you who explained anything to anybody a hundred times :) But don't worry I really don't think anybody has expected you to do that. You shouldn't overestimate your role and duties here :D
[Galaxy S II Q&A, Help & Troubleshooting] matabillions:
I actually did. But I wouldn't have had to, because enough people before me did, too. Then people with no clue who were too lazy to read the thread came, posted BS and confused everyone, even the developers.
[Galaxy S II Q&A, Help & Troubleshooting] :
Heh no offense but....lol Trust Me, developers are not that easy to get confused and especially 'noobs' do not posses such superpower. :D
[Galaxy S II Q&A, Help & Troubleshooting] matabillions:
Well, not even pulser_g2 could figure out what the real issue was, from the posts in this thread. And you can't blame him, because there's so much misinformation in here. So, apparently, people like Pfeffernuss have such superpower to confuse everyone.

I've been saying for a long time that it's a two-fold issue, consisting of a 650ms hardware lag (that can't be fixed) and an additional ~1s of software lag (that can be fixed, cause it was not present in GB and was fixed in JB).
[Galaxy S II Q&A, Help & Troubleshooting] :
I really don't think pulser_g2 or any other well respected developer base his knowledge about the problem on discussion threads where bunch of ordinary users try to exchange their personal opinions. Devs are devs because they try to figure that out by themselves. They perform couple of tests and when they succeed they share their observations with average users (or not). Not the other way round ;) EOT here

I have noticed this too... on every ROM.
[Galaxy S II Q&A, Help & Troubleshooting] donothurtme:
The same happens to me, seldom.

Regarding the lag:

My brother's gs2 with stock ICS seems not to have the problem...does it mean it is always wakelocked?
[Galaxy S II Q&A, Help & Troubleshooting] trikpa:
yes
[Galaxy S II Q&A, Help & Troubleshooting] randomseasons:
I think you are a bit too "detailed", yes I notice there is a delay, but it's like half or one second and for my taste it doesn't bother me, as a heavy rom flasher, I know it appears for a reason, the cpu went for deepsleep and it needs time to wake up, I think it's a must have effect, or else it will cost a lot of battery just to keep the cpu awake all the time, cheers ;)
[Galaxy S II Q&A, Help & Troubleshooting] Pirmas:
I have wake up lag of 7 s. it does not matter what ICS rom. Stock or custom. The lag makes me nuts... Some of you have 1 sec and youare mad, 1 or 2 sec. would be great.

If its normal considering to update from gingerbread
[Galaxy S II Q&A, Help & Troubleshooting] jj_95nano:
I'll answer my question myself... I tried JB and the wakeup lag is much lesser than ICS. Its quite close to 600ms.
[Galaxy S II Q&A, Help & Troubleshooting] garth719:
I'm at a loss when it comes to this subject. I own a Hercules and get this lag But not in stock tw roms or 10-12 jb cyanogenmod. Currently running 10-12 and there is absolutely no wake up lag. But the stable release of this same rom has the lag??... I refuse to believe it has anything to do with deep sleep. After setting the governor to performance it will still lag occasionally. I've tried every trick in the book to fix this and the only thing Ive found to solve this problem is using rrom cm10 nightly 10-12. That uses cm kernel 3.0.43. Something to take note of is that when cm team updated their kernel to 3.0.49 in the next few builds the wake up lag began

I also wanted to clarify that this is for the Hercules Although I thought i could help since this seems to be a common problem on a lot of devices. Also.... my phone DOES go into deep sleep with this build therefore proving that deep sleep is not the culprit

[Galaxy S II Q&A, Help & Troubleshooting] Beefheart:
I find it very interesting that plugging the phone into either a computer or a charger reduces the lag -- I have only just noticed this after reading the opening post. It doesn't get rid of it completely but it definitely reduces it to being barely noticeable.

I would have thought this would have made discovering the cause easier?
[Galaxy S II Q&A, Help & Troubleshooting] danieldeanhodge:
The reason plugging it in mitigates the issue is that this prevents the phone from going to sleep. This doesn't help us find the cause unfortunately.

Read an interesting report/Study today in a German online mag:

Most problems exist with android since it is installed on many different hardware platforms (= different manufs).

Best ist RIM (Blackberry) with 4 % hardware probs

followed by Apple iPhone; 16 %

followed by Android (a lotta different manufs); 30 %

The reason: Android has to run on single cores and dual cores from different manufacturers with different BT/GPS etc. sensors that might have their specifications but still are not exactly the same .........................

So maybe all these little issues are just hardware effects ....................

Hi all

Just to add I am also a suffer of this lag issue, it happens on my SG2 all the time

I have only task killer and set cpu installed but still my SG2 battery drain a lot quicker

Any ideas on how to go about fixing these issues??
[Galaxy S II Q&A, Help & Troubleshooting] Stylee32:
The main reason why there is wake up lag is because the phone is in deep sleep (when there's no cpu usage) - the reason why it doesn't lag when it's being charged is because the phone isn't deep sleeping.

I have already returned 2 phones for the "wake up lag+ Android OS" reason.... I feel that if any one posts that he/she doesn't have the lag should prove it with video running a stock ROM ( along with an optician/shrink paper :p).

So far, I've seen only laggy devices...more than a dozen...

Also, to my deeply horror, I've seen here a post from a well-known developer who was replying/asking a noob why is he so upset about the 1 sec lag, given the device is on sleep/suspend status and telling him about some MS crap...OMFG?????:confused: oh my, my 5 star dev, tell us again how magnets work?

A phone should behave anything else but laggy, from T28 to SGS gazillion , should be snappy as a whip, that's why I have a dual core/quad core GPU ON MY HAND instead of a 3300.

Let's face it, the SGS2 costs now as much as a small fortune for some. Given the time money ratio, it should take me back in time with 1 sec every time I press the freaking button, not make me wait for the miracle unfold before my eyes....

The problem also exists when you come off a call. The screen takes too long to wake up so you can press the end call button. This means you can be caught out if you or someone with you comments on the other caller before you hang up. I found this out the hard way :-(
