I have an overclocked Samsung Epic and it the improvement in speed in everyday use is significant. Because the processor voltage is set lower than stock there is no sacrifice in battery life. With the Asus Transformer do you get a definite and significant benefit from overclocking? I am not talking about test bench scores but real world noticeable responsiveness. When I skim through the forums it is difficult for me to tell? Some people swear by sticking with stock. I would appreciate others perspectives.
Thanks
The improvements from overclocking vary on the application.
Home screen switching is choppy regardless of overclocking simply because the launcher lacks optimization. Browser performance is improved a little bit, but mainly remains unchanged as well. Games run noticeably smoother, especially Fpse. Task switching gets a small boost, as some applications will be able to load faster.
If you're a big gamer, overclocking is definitely worth it. For everything else, it won't make much of a difference.
I haven't played too many games (mostly Stardunk and Stupid Zombies) on my TF, but I haven't noticed any issues with them. I have also played high profile 720p video with absolutely no stuttering or artefacts.
In other words, I haven't felt the need to overclock yet. But if you are doing heavy gaming and/or video processing of some kind, it might be worthwhile.
For me, there's hardly any need to OC. It all depends on what you wanna do. To many people who play a lot of games on their TF, they report increases in performance (especially with emulators) but on other things I never really noticed any difference. I'm currently underclocking my TF, and have been for about a week, with no noticable stutters or performance issues and have great battery life.
And it's not really an "effort" to flash a new kernel... the hardest thing is waiting for your device to boot up again...
I have a transformer, galaxy tab 10.1, and a xoom. I've used just about every kernel that can be overclocked for each one of them, and to be honest I haven't really seen any improvements from them. I don't really play many games on my tablets though, so maybe there really is some benefit in that area.
Galaxy's screen
How do you rate the screen of the Galaxy Tab 10.1? Is it as good as the Super AmoLED (+)'s from Samsung mobiles?

This seems so counter-intuitive to me. If you overclock a PC CPU there is a very direct correlation with performance. There are always limiting factors such HD acess, etc., but there is a definite and noticeable difference across applications. What is even more surprising is that we are talking about very large % increases vs what people can do in the PC world. People are overclocking these CPUs by 50% plus...You would think you would see a very noticeable improvement but that doesn't seem to be the case.
My main interest is in browser performance. For example, XDA forum pages load extremely slow in all browsers I have tried (stock, Opera, Dolfin) with 5-6s to refresh vs instant on desktop browser. Also flash video tends to freeze and stutter some times. My internet connection is over 20Mb/s down and 5Mb/s up. I was hoping that I would find overclocking safe and provide a noticeable improvement.

So for web page loading you haven't noticed much of a difference? How about flash video?
Thanks.
Overclocking can be a bit like collecting .. 'string' , because it is mostly done for the sake of itself, kind of like the many Ham Radio fans who talk about their "rigs", etc etc.
Yeah, of course if you can get, like in the old old days, a celeron 300 that overclocks to 450, and is dead stable, it was noticeable, and if you had a droid 1, which overclocked (many did) with ease from 500 to 1000+ , then it was again, noticeable, just not a staggeringly 2 times increase, because there are too many other factors.
The number of bus errors, and retries and slowness of the original bus speeds, and other components makes for a not-quite-as-expected by the numbers 'increase'. I would still mess with it, but not for the obvious reasons. I like under-volting more, and over-clocking only the slightest bit where nothing ever crashes or FCs. The moment you overclock, you really shouldn't be asking questions about 'Why does blah blah netflix crash?' because it crashes because you overclocked, and nothing else matters until you stick a kernel back at stock in there.
The other thing I love about alternate kernels is that you've got control of what modules you either compile in or compile and load as .ko files. cifs, tun, ntfs, whatever, it is all very useful, so there are lots of good and not-as-good things about it.
One thing I hate is when a dev insists on creating a kernel that has a 'default' speed greater than stock so that you've instantly got an ordeal if you've got one of the many gizmos that will not overclock to his default (like 1.6 to pick a number out of a hat).. Just make them all start at default, then allow us , the users, to setup overclocking via testing with setcpu or some such thing. Much easier than basically bricking things right off.
I sometimes look at those guys that overclock 'seriously' (by 3-4 times) using a container of liquid nitrogen that lasts for ~5 minutes and it is all for bragging rights, setting records , etc and think they're insane, but that is also part of it. Some are happy if they can just post here that they got 9,000 mF on some test despite not being able to do anything else reliably.

Great post!
+1
Very philosophical ! ;-)
I guess what I am getting at is if you overclock to 1.2Ghz-1.3Ghz on the Transformer can you have a stable system that shows an appreciable improvement in responsiveness? Moving from hypothetical to actual...have you done this? Any specific kernel?
The engineer in me is looking for a definitive answer. ;-)
Thanks.

Yeah, I've done this, just not on the TF yet. I'm working on a kernel right now that doesn't have OC built-in and activated at boot, so that we can use setcpu to screw around with it and find that 'sweet spot' that works for us, also under-over-volting. What I'd really like is to build in all the modules I like, setup over/under-clocking-volting and have it boot at 1 G. I mean, a dual-core 1G is nothing to sneeze at, and then try to ramp it up without screwing with over-volting immediately. I never like other peoples ROMs or Kernels because they have made their own crazy judgement calls. I like my own crazy judgement calls
Here's what I've noticed: When you have 'up-to-date' technology , as we do, in the TF, then overclocking that is totally stable makes a difference and it is noticeable. For me it's the FC's that kill the deal, but this chip and box appear to have plenty of headroom so I'm guessing that 1.2, 1.3, 1.4 are all good possibilities.
Example: My HTC Incredible phone has been overclocked to 1.1 from 1.0G for ~a year or so, and it doesn't FC, and it is faster, noticeably than at 1. It's only a 10% increase and yet it feels much quicker, so go figure. Those things are also subjective, so grain of salt... Example2: A stock droid1 is one I took to a double overclock, 550 to 1000, and yes it was faster at some things, but the underlying infrastructure didn't really support the faster CPU so I really never noticed a 100% increase that matched the clock speed. I left it that way for a year without any damages and it still boots up fine at 1 G.
In another post I started, I was asking what keys were required to boot 'safe mode' which exists in android OSs, and if I knew that, I'd try one of the OC'd kernels right now. IF not, I don't feel like unbricking again.
If you're interested, here's a good link for building your own: (generic android, not TF really:
http://www.droidforums.net/forum/rescue-squad-guides/31452-how-compile-your-own-kernel.html
Thanks for the response. With such a large community of Transformer users I am hoping to find a solid, conservative kernel that I can overclock with. Creating one myself is beyond my current technical capabilities.
I am considering using a custom ROM on the transformer, but is it worth it, I am mainly after performance increases. I see on a few that there are higher benchmark results, but does this actually translate into a real world speed increase?
I remember some custom ROMs for the original i9000 Galaxy S doubled the benchmark performance, but that was more down to "cheating" the benchmark than anything else, although it certainly was noticeable at times.
One of the slight criticisms I have of the TF101 is a slight amount of lag / lack of responsiveness occasionally - not a deal breaker, but if it can be improved then why not? Obviously not at the cost of stability though.
I think the SGS2 has spoiled me a bit here!
apparently there is a big increase (mostly from overclocking). i had the standard firmware for 3 days only, so I can't really tell, but one of my co-workers has a locked B70 and was wow-ed by my TF, the smoothness and speed of it.
Yes, I'm waiting too, to root it and put a cutom ROM on. I read, heard and saw the performance difference. Mainly from the overclock, but also thanks to kernel tweaks and stuff. So If you can root, do it

I've never been that keen on the idea of overclocking, as I prefer to have a bit of headroom, but I guess if it is safe and makes a big difference, then I would give it a shot. What would be a good middle ground for stability / speed ?
1.4 IMO is very stable and doesn't increase heat or use more battery but the real world performance is noticable. I have never run a benchmark so I can't give you any numbers. Just my normal use.
Cheers for the reply.
Is there any one ROM that stands out as being the best performing?
Contrary to what people think they all perform about the same. There is no source so everyone is building of the same stock rom. If you want the same look then go with Revolution. If you want a little tweaked then go with Prime (What I'm on). If you want the tweaks and a nice tools package then go with Revolver (What I was just running). All 3 devs are really responsive to problems
If you start from a clean base and don't restore any system data from other builds then they will all be fast. The real speed difference is in the kernel and those can be flashed seperately from the rom. Clemsyn is really putting out kernels this week. Some good. Some not so good. Go with whats right for you.
EDIT: I have actually installed all 3 roms in the last week and run them at stock and at 1.4 Ghz. They all performed exactly the same for me. They were all equally stable. I don't use benchmarks because they can be fudged.
I've used all three too. I notice huge improvements with webpage rendering. It's almost as fast as my laptop, where as before I avoided using the browser if possible. The ability to hide the status bar is a really nice addition to the latest version of revolver.
Edit: autorotate is also alot faster.

There is no such thing as an overclocking "middle ground" when dealing with mobile chipsets such as the Tegra. It's not like overclocking a desktop computer where the CPU will constantly run at the specified speed; mobile chipsets are pre-configured to utilize only as much power as necessary. For that reason I always ramp up my tablet to the max clock speed it can reliably handle, because then the governor will handle balancing between speed, stability, and battery life. My clock speed can range from 216Mhz to 1624Mhz, and on the interactive governor I can still achieve a good 8 hours of battery life from a single charge.
Of course that's not to say that you couldn't constantly run at 1624Mhz all the time, and I do sometimes lock it to that speed for games. But for much of the OS interaction, it's not necessary to run at full speed all the time, and you won't notice a difference even if it is locked at full speed. It just comes in handy every once in a while for things like loading apps, loading web pages, and playing games.
I'm finally receiving my MyTouch 4G Slide today. I was just curious how the performance is? Is the stock ROM worth wild? Does anybody play N64oid, or PSoid on there phone? If so, how's the performance? Also a personal stand point whats your favorite ROM?
I want to try out the Port of CM7, but Sense 3.0 is pretty neat. If anyboyd is running a Sense 3.0 Rom, or CM7 would they recommend it?
cm7 > sense
The Sense that the MT4GS is vastly superior to previous versions of Sense, but I'm still waiting for a viable release candidate of CM to come out.
Your battery drains pretty fast with 3d games, and if you charge while you play, your phone gets hot as hell, I recommend rooting so that you can keep it underclocked as much as possible while you play. Gaming performance is good enough that you don't need full cpu power

...as I sit here in my car waiting for my shift to start, i'm playing Castlevania: Symphony of the Night on Fpse. You can find it in the google market, and if you have any old ps1 games laying around it's worth every penny.
Works great, when i'm at home I plug the phone into my t.v. and play it that way. If anything I think it runs more smoothly when plugged into the t.v. - the audio syncs just a bit better with the same settings.
Checked my email and figured i'd cruise through here real quick before they let me in to get started.
Haven't had a chance to play with n64oid, I don't have any n64 games around anymore so I passed that one by.
About the stock ROM:
Horribly bloated, full of crap, loggers and other BS...you can find the info in a few threads around here.
If you decide to stick with the stock ROM, freeze, uninstall or kill the zipwhipgroups apk and also flash Undeadk9's security patch. Those two actions should close all known security flaws to date.
I've played with all the ROMs available, and they all offer something fun approaching the phone from different angles.
Play with them and i'm sure you'll find something (honestly...anything) better then the stock ROM.
My daily-driver keeps ending up being my own frankenstein, and once i'm basically out of a job when december hits i'm looking forward to mostly finishing it off.
Performance-wise the phone is fantastic. Even on the bloated bogged down stock ROM it still flies, and once you start flashing some of the more optimized ideas people have shared with us, you'll be even more impressed with it.
Make sure you hit up the battery thread floating around here to see why you should switch away from the stock HTC battery. I use an anker battery, and couldn't be happier - but you should see what siani_8 has to say about the Mugen batteries. Pricey, but apparently worth it. I found my anker battery for just a few bucks on amazon.
The stupid stock battery gets ( to quote another members apt description ) "Stupidly hot". Heat is death for a device like this, and whether you go with a mugen or anker, you should switch for sure if you're going to get into gaming or pushing the devices limits...otherwise you'll burn it up.
Just make sure to cruise through my backup thread, link in my sig, before you go flash happy. It'll probably make life easier for you in the long run, and it's a good review even if you're already familiar with it's contents.
Always happy to see new faces around, and you'll love the device. Best of luck!
Thank you all I read a lot about the battery issue. Considering getting one, but I might just run at 800mhz. I'm coming from a G1, and iPhone 3G. This thing fly's! But I'm having another issue, I can't root. Everything is set up right. But Rev. hangs on Zerging Root?? Or is it supposed to do that? I haven't rooted in a good 3 years. Any help is good help ;D
Also all the Emulators work, even the super buggy NDS one. I kept all my older games so I have the "Legal backup". But the games that needed the expansion pac run slow with sound on. But there on http://slideme.org/ if anybody want's them.
I'm a bit lost on performance with the MT4GS. In all my testing so far I have been getting my best benchmark score with stock rom and stock kernel without overclocking. I've tested with multpile benchmark apps and consistantly get lower scores using custom roms and kernels even while overclocked up to 1.7 Ghz. The whole thing has me baffled at this point. Using quadrant advanced I average 2100 range with all stock, compared to 1800 average using custom and overclocking. To add to my confusion, my original mytouch 4G with single core is averaging 2800 in quadrant while only overclocked to 1.1 Ghz.
I must be doing something wrong, by all rights the slide should be scoring much much higher.
Does anyone have any ideas why I'm getting my bizarre results?
Thanks much everyone.

Usually benchmark scores that are lower are better.
Not always, but in most cases this is true.
Quadrant didn't support dual-core processors, or well, or something if I remember right. I mostly ignored it when I was benchmarking things not long ago - wasn't working right on our phone.
Say what you like about Sense, I'm not a fan of proprietary junk either, but they have the camera right on this one. There's zero shutter lag, and the camera has the features and response of a mid priced point & shoot. It's one of the best cameras in any phone, and would sell for a nice price even if there were no phone attached. And that is largely because of the Sense framework on the back end.
Because of that, I highly recommend UndeadK9's Senseless ROM. This ROM is an AOSP themed ROM but he has kept the Sense framework on the back end, but only where it benefits us. He is very sensitive to issues with the ROM and responds to (i.e. usually fixes) them very quickly. And he posts on here as if he doesn't have a life.
If you use his ROM tip the man, he deserves it.
With quadrant i was getting better scores from my mytouch 4G, but if it is only using one core then the odd results make much more sense.
One thing that has had me confused is with custom roms and kernels on the slide, when I run benchmarks, my scores are about the same regardless of being overclocked or running stock.
Based on the scores, it looks like overclocking is having no effect. I can say that there are definitely performance increases with the slider regardless of what the benchmarks say.
I did try UndeadK9's new rubix rom, so far I'm very impressed.
Sent from my myTouch_4G_Slide using Tapatalk
Imo there is nothing wrong with the stock rom. It has very few bugs and my phone scores 4650 on antutu. I was one of the first people to get the phone, online pre, and I got the anker battery. The new security update from tmo also gave me better 4g signal. I have only three gripes with the phone.
1. It doesn't run at 1.5ghz which it is fully capable of
2. You can't name homescreen folders
3. There is no true favorites
If you want the phone just to run cm7 vanilla don't buy the phone and get a newer gx2
Maybe i am wrong but it looks like there is something weird with 2d/interface performance of my Sensation.
Currently i am running latest Hypersensation with latest Faux's kernel (ADW Launcher) and i have tested a lot of other ROMs and launchers..but on all of them i am getting nonsmooth interface. Kinda laggy.
I mean, in sense, everything is fine (in the meaning of that word, not supersmooth but fine), but when i try Zeam launcher's drawer (with 6x6 grid) which is superlightweight it gets laggy. In ADW (6x4) it's laggy too. In Go Launcher not too much but i am still not happy. And it's the same with Launcher Pro.
And effected homescreen - switching is not smooth at all. I even tried overclocking my cpu, but it didn't help.
Before some time, by sensation has fallen on the floor by left down corner (and now i have deep scratch on the external casing) - could it damage by cpu in any way? I hope not
I am getting scroll lags in some apps (twicca), new twitter app (released today) is laggy as hell (when pulling to refresh, to be accurate) and new facebook.
However in games it's fine and i am getting around 12000 native cf-bench score with overclocked (1,5 Ghz) CPU, so this is indicating that there is no damage to CPU.
Maybe i am too demanding, but this performance in ui (which you are using most of the time on phone) is not what i expect from 1,2 Ghz DC phone.
Is anybody out there experiencing similar issues? Anyway to fix them? Thanks in advance, guys!
I have attached twitter video...30 fps via screen recorder high quality settings:

I suggest using a Sense rom, they tend to have better performance, but switching launchers. The guy who makes HyperSensation also has a no sense rom, try it out, it's really fast and smooth. As for ADW, get ADW Launcher EX, ADW just plain sucks, but EX is very fast.

As long as it's still running, I doubt it. These phones dont have any moving parts, so it's not like you busted a cooling fan or anything. You're not the first to bring performance concerns to the Sensation. And frankly, I've noticed it too sometimes. At times I feel like I'm using my G2, but the good news, ICS will have a GPU accelerated UI (like the iPhone does) so performance should greatly improve soon, hang in there brother.
Thanks, i forgot to mention that i have used all launchers mentioned above with sense rom, with sense disabled via app manager (frozen) and e. g. mentioned zeam sucked. But iwill give ADW EX a try..especially when it costs 0,1 euro
http://forum.xda-developers.com/showthread.php?t=1350492
There's that non-sense rom I recommended. ADW EX is definitely worth the money, you'll notice an instant performance difference over the standard ADW. The only thing thats laggy about it (on any phone) is if you set a transparent drawer, since it's not GPU accelerated, that'll half your FPS. Hope it goes well for you, it's a shame that even with Sense disabled, you're seeing problems.
Edit: Have you tried either the Faux or Bricked kernels?
Thanks for tip with ADW Ex, it is totally smooth now Zooming animation still isn't perfect (when going from homescreen to appdrawer) but its ok. I have never thought that EX is this big performance improvement.
Funny thing is, I have the same issue. I changed the zoom duration to somehting like 300 or 350, speeds it up so it doesn't look as bad, but I can't find a solution. Atleast EX is running good though.
Hello there! I was in the same boat with my sensation. Unhappy with the seemingly laggy interface of my new 2core phone. So I rooted to reverted aosp with 1.7 kernel and this is about as snappy as I wanted it to be from the start , I'd suggest trying it out
I have something to add. I tried multiple Sense and No-Sense roms, and that homescreen to appdrawer animation is perfect on all of them. I flashed the bricked kernel, but I'm pretty confident that that's no required to get that animation smoothed out.
Hi ,
currently I'm running CodenameAndroid 3.3.0 on my Nexus S and everything runs smooth and works perfectly well for me, no doubts. But somehow I constantly get the feeling that the newer our operating system gets our batteries drain faster. Either this or my battery just gets old. However I'm searching for a Rom that has battery saving in main purpose. I dont care about playing games, the operating system or showing off how great my phone is. For this I have my Tablet The best solution for me would be a rom which is very low in batterydrain but as smooth as jellybean (maybe just port the transitions over). I know it might be hard to find something like this but is there any rom which matches my perception? Also a nice look would be cool, too ^^
I'm waiting for your responses!
I think you're looking for SlimBean. I'm on CNA too, the batter life is pretty bad
I tried SlimBean because I used SlimICS before but I miss too many features to change it back. Isn't there something else? Or which OS has the best batterylife in general?
i think gingerbread still has the best battery life.
androxide got me over 4hrs of screen time and a days usage with matrix
the new miui jb is also almost the same
IMO.....ICS's best battery life is on Kangy Ultra Ex 1.3 by DaXmax.
Just as long as u don't use Google talk since that's the ROMs only hiccup.
Then again like most will say.... its all depending on the user so hopefully it will help if u try.
I'm currently using the same developers JB ROM called paranoid Android..... so far it great but again I don't use all the newest features to much yet. I'm working myself slowing into the stuff.
Good luck
Vs Nexus S4G using tapatalk2
There is no ROM with super battery life, some better and some worst, very similar.
Most u can get from nexus s is +4hrs screen on.
And i don't care about those pathetic screen shots with +7hrs of screen on.
Fire up 3g/H stock browser, maps, music etc and we'll find out how good ur battery life is.
MIUI get's me aprox 4 hours and 50 minutes of on screen time. Lots of game playing, instant messaging, syncing, music, and social media (Instagram, twitter, tumblr.) And about 9 hours + when it get's to about 14%
EDIT: This is when using WIFI, not my 3G.

This question will produce every combo under the sun...but in the end no Real answer. Every phone/battery is different and how the person uses their phone. Apps installed, how much you use said apps, are the ram hogs, 2g, 3g, I could go on forever...just like this thread will if not eventually ignored or closed.
Closed, there is no answer to this question, the majority of battery drain will be the screen (depending on brightness) and whatever app you have installed and use.
Generally it's a matter of finding out what works for you.
