There is a very nice article on the performance of high end Android phones at

See Attached pictures. The major blow is that there will be no joy in upgrading stock to A2.2
The memory speed in SGS is superior to the competitors. The processor is basically the same ARM 1GHz. But the overall performance lags 4 to 6 times depending on how you account performance. Respectively, the battery drain will be inferior and the lags continue to drag on.
Most likely, the infamous time lag issue that is related to "inefficient" memory management plays the role. There was no official Samsung reaction upon the issue. Considering how memory management is done now (the device -most likely- minimizes memory triggering, doesn't close unused apps despite significant battery drain [200+ hours after boot up, wifi, 2G cell, no apps touched vs. less than 24h if you use apps along the way]) and the deliberate ignorance of the situation on Samsung's side, one can conclude that there is a reason. It could be a short life time for the memory cells, i.e. trade off speed vs number of write cycles. Or something else of the sorts.

I agree, it's a decent article that helps explain some of what composes each benchmark. I do, however, believe it missed one key point regarding the 2.2 beta benchmarks. From everything I've read, the Froyo beta ROM hasn't even enabled (muchless optimized) the Dalvik JIT compiler that accounts for the huge differences in CPU performance shown on Page 2. Essentially, the graph shouldn't show the 'Froyo / beta ROM' result in green quite yet. We're also not shown the great benchmarks resulting from lagfixes. I don't know if that's also true with the Froyo Legend, but it certainly discounts the full potential of our Galaxy S phones.
Seeing how well the Galaxy S ranks otherwise leaves me thinking it remains the best Android hardware available today. And with all the positive feedback I'm hearing about software fixing both the lag and GPS issue, I'm quite excited. But only time will tell and I, for one, can wait for the devs to finish tweaking and testing things for us. Now if there were a port of Quadrant for jailbroken iPhones, we could compare those too. (There are a few Linpack attempts but they don't seem to be reliable.)
Error all over the place
First of all I didn't like this article at all.
Also, someone should notify them that their conclusion is wrong. The Hummingbird is 45nm, not 65nm
Yeah, I think it's weak they're comparing a Galaxy with an unofficial Froyo install versus ones that have had matured Froyo for a while. And it's their only data point for claiming that the Snapdragon cores benefit from Froyo more than the OMAPs or Hummingbirds... kind of a weak claim before we have some more data.
Patience,and time, will show what the Vibrant will perform much better with actual 2.2 vs. the builds used in the review.
I have never been an Iphone user so this statement comes strictly from a third party observer perspective, but when I see my friends using their iphones I do not notice the same lag that I get with the vibrant. I have implemented the lag fix but I still have some lag. I had the same problem with the mytouch 3g...hopefully it's not an android issue. Is there significantly more lag on the vibrant than there is on the iphone? Just a question....

I have never been an iPhone user either but speaking as a vibrant owner who is in the IT industry ( which is over dominated by apple fanboys), I have to say that the Vibrant has an equal ammount of "lag" to that of its fruit derived cousin. My comparrison is stock Vibrant vs stock iPhone 4. When comparing my vibrant to previous models of the iPhone I can clearly see a difference in performance in my favor... My cube-mate used to lord his iPhone 3gs over my G1, and now he is waiting for his contract with at&t to expire so that he can get some galaxy s love from verizon. Lastly, I break lag down into a simple definition of: the difference in time from when you initiate any given action until that action comes to fruition. Useing that definition I look at browser load times adressing a null http page, the refresh of the home screen from an unlock swipe, and the click of the settings option. On all three tests the Vibrant preforms on par ( if not slightly better on the home screen from lock) with the iPhone 4, and gennerally much better than previous models ( i dont hold previous models as relevant as they are not direct competitors to the vibrant). All in all the Galaxy S line of handsets not matter the carrier flavor, are powerful devices and if you are looking for something to be the iPhone.... get an iPhone.
If you really watch you will notice it. They use animations for transitions more than Android does. The time to launch apps is usually similar. That said, the galaxy s series has lag with programs at times do to a crappy file system. I haven't tried it, but people say the Voodoo lag fix works wonderfully.

Hey guys!I'm planning on getting the Samsung Galaxy S soon.But now I'm actually stuck between this and the Samsung Galaxy S.I'm aware that the processor aka the 'Hummingbird 1Ghz processor' on the SGS is faster than the Snapdragon processor on the Nexus One.I'm not really going for the looks but I've realised that the SGS has a lagging problem and I believe that rooting and using the one click lag fix can fix that but I'm not planning to root my phone and I'm going for the SGS mostly because of the large internal memory that can keep lots of apps and the bigger and clearer screen!While the Nexus one only has 190mb available and I believe the Nexus one has some hardware problems like dust under the screen and something wrong with the touch screen.So please help me with this!And lastly,I may also choose Nexus One because its gonna receive all the updates in the earliest time and that's a big advantage!So,please help me with this!
My wife has a bone stock vibrant. It has very little issues with lagging, at least not more than a non-modified nexus one. If it were a lag fest, she would've asked me to get her something else. There are areas the nexus doesn't lag that vibrant does, but many more areas the vibrant runs through that the nexus stutters.
Stock for stock; vibrant. The nexus does get more overall support, but you've already said that's not what you're in to. Heck, even mod to mod I'd keep my vibrant. Lag free and fast.

You could get the Nexus S and get the best of both worlds. It's a Galaxy S (upgraded) with 2.3 Android right now. And since it's another Google phone like the Nexus One it will get OTA updates faster then other phones.
Its actually the Samsung Galaxy S I9000 I'm taking aboutAnd the place I'm buying from,Nexus S isn't available yet.So I'm now only stuck with those 2 choices!
I've played around with a friend's Galaxy S ... to me it's terrible. I can't get over the BACK button being where it is, or the slowness due to it being packed with Samsung and BELL junk, or just the fact that it's plastic... terrible terrible phone.
So its just the placement of buttons or did your friend really mention that its a bad phone?
The funny thing is, is that I actually own a Vibrant and hardware wise I have to say it's an amazing phone. It's definitely better in hardware than an N1. What I love about the N1 if definitely software support and that it has a camera flash/flash light. It depends on if your going for hardware vs software or if you really need an LED flash. As far as lag goes, I used to experience lag till I upgraded to the new unofficial Froyo build released yesterday (12.20.10) by T-Mobile/Samsung. The phone is very fast/responsive now. Maybe not faster than an N1 out of the box, but you can modify it to be just as fast if not faster. My phone is unrooted running 2.2 JK5. Although I might trade this guy in about an hour who has an N1. The only reason/reasons I want to trade is because I love having flash on my phone and all the Dev support from google and the N1 community, although this is my first time ever being in the N1 forums. I hope if I do decide to switch today or tomorrow that I am welcomed by you guys.

If your phone is ' un-rooted', how are you running a custom rom? (2.2 jk5 is a custom rom, I'm guessing). I know I had to root my Evo in order to flash roms. (as opposed to 'unroot', which is how it comes out of the box).
I would suggest nexus 1, even just based solely on hardware and build quality. Samsung phones have this terrible cheap plasticy build/feel. HTC phones have a much better feel and build quality, in my opinion. Also, it sure sucks to have a camera and not be able to use it if it's the least bit dark.
Just my .02¢

I definitely value your opinion. The Vibrant was able to upgrade to the unofficial build because its similar to an ota, but you just have to manually push it to the phone. You can check out the Vibrant forums for further explanation. If anyone is wondering, guess who has an N1? Lol. I traded the Vibrant just now and I must say I'm impressed. It does feel solid since its actually made out of metals in opposed to the Vibrant's plastic body. Only thing I miss so far is the Super Amoled display and lightness (weighs less of course since its mostly plastic) of the Vibrant.

unless you're heavy into games and multimedia it really won't make a difference. with the nexus 1 you get that fast google support. And it's a great phone.
If you are into games and videos hands down vibrant. Especially now newer graphics intensive games are coming out.
I own a vibrant with nero 3 voodoo on it. it's ridiculously fast and gps woes are a thing of the past. The support is there, just not directly from sammy. So there u go.
i LOVE my galaxy S and would never trade it...go for it
Has anyone noticed that the Galaxy Note is not as fast as it should be? I compared it to a Galaxy S II and the SII was just buttery smooth in terms of speed compared to the Note. The more I played around with the SII the more I noticed the speed and smoothness difference, and it confused me because the Note has a faster processor so it leaves me wondering why the Note is slower.
EDIT: I don't know if anyone else has noticed but there seems to be a very slight lag between input and the phone responding, for nearly everything. From swiping/scrolling to opening up apps, there just seems to be a bit of lag. The SII does not have this, that I can see. Everything is almost instant on it, as soon as you give input to the SII it responds.
Also, for those of you who are lucky enough to have upgraded to 2.3.6, is there a noticeable difference in terms of general speed and smoothness?
Exactly.........
Same i observed as well with d demo piece kept in the shop.
Note is bit lagging than the galaxy s2.
Please answer the question. Did firmware update 2.3.6 improved performance?
Can ICS update make it as smooth as s2 or nexus?
Thanks in advance.
I dont know wat u guys are talking about.. My notes smooth.. And i had owned a s2 before..
And relax, its the initial days of the note... More updates will come. And ics is only gonna make it better
Sorry but I have to disagree. I would say my Note is buttery smooth, insanely quick & responsive...
I've never owned the previous Galaxy S2 but have tried it in the shop and it's no way any quicker, infact it was choppy at times...
I take it it depends what apps you are running since certain apps are buggy and cause problems such as the device being sluggish at times?
My note has never lagged or been slow. I'm running the stock launcher. I tried others but did not like them.
List of installed apps:
Flash Player
File Manager
Viz Battery
Wallpaper Wizardrii
Smart Keyboard
Beautiful Widgets
Angry Birds (all three)
Yahoo Messenger
Msn Messenger
Skype
Barcode Scanner
MixZing
MX Video Player
Adobe Reader
Opera
Equalizer
I notice that the Android OS uses about double the display. Also when typing fast there is lag. I know about freezing apps, but ill just wait for custom ROMs.

i am so pleased to hear this.....
i have not yet bought it, yesterday for the first time i saw a demo piece.
Dont know why but i found it bit laggy. Maybe beacuse the expectations with which i went there.
anyways will need to see another demo piece b4 so that can buy without a doubt...
Bare in mind the note has ~3 times the resolution of the sgs2 and is only ~14% faster, presumably that accounts for the difference in experience some users have.

of course we know that.........
i just want to know is it really slow than S2? (whatever may be the reason)
I still got 2.3.5 I'm very picky about speed in my phone, one thing I have noticed is that whenever memory gets really full the device suffers, say for example you launch the default browser and it's choppy, just try this: launch the task manager and do a clear memory from the ram tab.relauncb the browser and compare the speed, lighting fast!
I belive that it somehow loses the hardware acceleration at one point, so next time you guys try one specially at a demo stand, just clear the ram and give it a go.
Input lag is something I haven't noticed, what's more typing using SwiftKey is truly an experience! Zero lag and lighting speed! So I wouldn't worry much about it I'm pretty sure it has more to do with the early stage of the firmware than the lack of hardware to do it.
I truly belive speed is not an issue on this device,it's by no means perfect but it's definitely an experience using this screen with this power under the hood
Also I totally agree about the underrated s-pen people still don't realise that this is not just a piece of plastic with a fine tip, the pen is not crappy one like the horrible stylus on windows mobile phones, this pen uses a magnetic technology developed by wacom, what this means is a mix between accuracy an speed of capacitive touch also let's not forget that it can detect and separate between a normal finger press and pen press it had the potential of doing mouse hovering, not yet implemented on gingerbread drivers, also it finally brings pressure sensitive to the artist so it truly can be used as a sketched on the go!
Download if you want to try the app
Multitouch visualizer 2, so you can see how accurate the pressure and the pen itself is!

The only reason S2 is faster is because it has a laughable super low res WVGA display. Low pixel counts = faster rendering time.
Hi,
Please check the attachment. It is the screenshot of my version on my galaxy note.
I bought my phone yesterday. I connected and and updated firmware using samsung kies software. Now the screen is lagging while scrolling. Please check and suggest something.
Thanks

I just updated to DTB PDA KK9 and it feels smoother. Launcher Pro is not stuttering as it was. Battery life infinitely better. Still 50% after a long 16hr day of quite heavy use as opposed to 15% after 8hrs.

Isn't the Note pushing twice the resolution of the GSII?
It doesn't take a rocket scientist to figure this out folks
No lag on mine. Justas fast as any other device

Probably because it was a demo unit.
I'm running exact same setup on both SGS2 and the Note (Launcher Pro, Widget Locker, etc) and SGS2 definitely is noticeably smoother than the Note in UI operations
Hey Guys,
ever since i use Android im kind of annoyed by the responsiveness of the tochscreen. Even with state of the art smartphones like the S3 (ICS version) there is substantial lag. (compared for instance to an iphone)
I was really excited when JellyBean was announced because as it seems, it addresses the issue.
However when i tried an S3 with JellyBean i still felt the lag.
My question is whether the Nexus 4 actually matches the Iphone in responsiveness.
(I do not mean the stuttering when opening for instance the app drawer, i mean the pure relation of the finger touching the device and the quickness of the response of the device.)

It uses the same new technology as the iPhone 5 which brings the touchpanel closer to the front glass meaning responsiveness should be significantly better. It's called In-Cell Touch display if you want to Google it.
You'll get a real answer when the phone comes out. Or check video reviews. We know as much as you do at this point.
Thanks for the answers enviii and ralexand!
The thing is, this input lag issue is very rarely adressed. It seems to me as if most poeple dont even notice it. It may be that im kinda picky there but its definitely a very important feature for me...
As the device has been released I would appreciate someone talking about the mentioned issue, who actually posseses the phone.

lol... that's just not true. It helps viewing angles, but has absolutely no effect on responsiveness.
The thing is, It could be or could not be,I think its just what peoples definition of smoothness and response is. Never know until the phones out. IMO

Well for me the scale is definitely the iphone. (even still the 3G when scrolling homescreens) Also top notch Windows Phones offer very good responsiveness.

I guess it would be better for you to stay with iPhone.
EDIT: Deleted
iPhone relies on a system that basically delivers all or much of the available resources to the graphical interface when scrolling, which slows down or stops whatever else the phone is doing at the time (ie stops loading a web page when you start scrolling or momentarily pauses a download). This, along with a very strong GPU, is much of the reason for the smooth interface. (note: this info was taken from an interview with a Google employee, probably about a year or less ago. Could be outdated, but I believe it's still true...)
4.1 ramped up graphics rendering FPS to 60fps. This, a long with a strong GPU, S4 Pro processor and (mainly) 2 gigs of ram should result in an incredibly smooth UI. Also, the curved glass on the edges of the screen have been noted to give a much smoother feel to scrolling, whether it's a placebo effect or not will just have to be determined over time.
Long story short...yeah, this thing should be smooth as butter (pun intended)
Also iOS is more optimized since its on for few devices.
Sent from my Ally using xda premium
actually the big main reason for smoothness of ios vs android is that...every single application (basically everything) runs on virtual machines on the android unlike ios.. so it is true that the beefier the hardware the smoother the device..and thats y ios is able to run smooth even with lesser hardware..

Thanks for this in-depth information. I have already known some of this from posts by google employees on their google+ pages.
I hope the changes introduced in JellyBean and the sheer performance of the Nexus 4 can overcome the innate performance issues of Android.
When someone has made first real life experiences with the device please let me know

I have a Nexus S (awaiting a 16GB N4) and I can tell you that Jellybean offered a tremendous improvement in smoothness.
As for the lack of improvement with the S3 and Jelly Bean, do keep in mind that is not "stock" Jellybean, Samsung may have avoided using any of the "project butter" code for their own GPU rendering.. Only Nexus devices are guaranteed the advertised improvements listed by Google, once an OEM touches there's no guarantee.
Only the framerate is high. There is MASSIVE input lag of 100-200ms on every Android device. As evidenced in every video of the Nexus 4 the screen lags behind your finger by 1 inch or more when swiping. This makes it feel extremely sluggish and unresponsive in apps like Facebook and games like Canabalt are unplayable.
I noticed this too when I first started messing around with my N4.
A test I like to do is use the calculator, and see how many numbers I could hit before they would be highlighted (which I assume means the device starts registering the command). For some reason I was getting 2 (almost 3) punches before the device would see it. On my Wildfire S and my iPod Touch the input lag was never this bad.
Amazingly, I actually found a solution. I don't remember if I turned it on myself or if it came on by default, but my phone had the "Magnification gestures" on. You can find them in the "Accessibility" settings. I turned it off, and BAM! The input lag has practically disappeared. I don't know why it was doing that or how it's related, but this has effectively fixed it for me. There may still be a slight input lag, but it's small enough that I can ignore it. Before it was easily over 500 ms.
Hope this helps.
I've made sure that's off on every Android device I've tested. The input lag is still considerably worse than the iPhone.
