(Q) Fast Five App Lags - Epic 4G Q&A, Help & Troubleshooting

Even when i Over-clock my phone and have the governor set on to on-demand.
It lags a bit and seems like its FPS is low but then will go to max FPS but then drag down again its weird.
Im on Genocide right now and its funny if i UV my frequencies by -25 to -50mv for 200-1200. its still heats up to about 100*F and thats with the charger on but if charger is off it cools down to about 86*F?
Why is my phone heating up just because its on charger and why does it lag even when OC'ed?

Its normal for it to heat you like that on the charger. Mine gets real hit too. As far as the other question change the scaling of the kernel. On demand can be like that sometimes. It tried to stay at the lowest speed but it will go up higher if need br and that is why u are getting a little lag at first.

The problem with that though is on-demand is more geared to stay higher whereas conservative just keeps low, and the only other one that works is also performance but that keeps it up as high as you have it set to which will then heat even faster.
With or without the charger

[Q] setvsel cpu damage

hey guys, just wondering will using a lower vsel damage my cpu and/or battery?
i have previously beein using milestone overclock on 1ghz and 60 vsel and am adding setvsel into the mix, also any ideas on starter settings? thanks
also could someone just give me a heads up on what vsel actually IS
I don't believe there are any studies that show effects of long term use of lowering the voltage, which is what you are doing with vsel in order to save battery juice...or you could increase the voltage but that defeats the purpose and also heats up the battery which leads to shorter life span. Many use it without reporting any damage to battery or cpu, I believe it's safe (however, if you are overheating you might fry the battery or cpu, so you'll need to moniter and play with settings to get the desired effect without any overheating issues).
With regards to setvsel, there are reported issues from users with different roms...from what I've read (and you can do your own research to see if this is what you are seeing...this is the conclusion that I've come to by reading a lot of threads), it is better to use milestone to overclock and setcpu to lower the vsel.
With that being said, I've used them all and like setvsel so keep going back to it...but I've been having some issues lately so I've removed setvsel to see if that is what is causing some problems (too early to tell).
Oh, and as for settings...pop on the overclocking/undervolting thread in the development section to see a lot of different settings and remember that what works for one user might not work for you...you'll have to experiment a bit to find your ideal setting.
oh okay i think i might go back to my old settings with milestone overclock and setcpu and just lower the vsel! i was under the impression for some reason that lowering the vsel would heat the battery. Thanks!
I'm no expert to be honest, I'm more of a research kinda person. From what I've researched, undervolting can help keep temps down, and may particularly help when you overclock (as overclocking is stressing the cpu to go beyond it's normal operating design hence it may heat up...supplying it with less power, or voltage, is what helps keep the temps down.
Of course, this is given you find the optimal setting for your phone, and as it seems from reading through these forums, many users have experienced completely different results using the same settings (i.e., one user will have a stable setting without any problems while another user on the same rom using the same settings will have crashes and/or issues like overheating). Doesn't seem right, but it is what it is
yeah ive read through most of that stuff too, i went down to 1ghz at 51 vsel, seeming stable, but i decided to go with 54 anyway
1.1 GHz @ Stock vsel for over a month without any issues...I hope it lasts.

Hi,
I've also read a lot regarding the underclocking 'dangers' but couldn't find anything to prove that there is such an issue. I think that it is an urban myth spread everywhere by people asking if there is a danger with low vsel [but that are never getting a positive answer on it].
The only thing I found using setvSel is that I had to first install Milestone Overclock and load its module prior to start setvsel. There is a way around it, but requires you to copy files in the system folders and change their permissions. I find that my way is much easier.
As far as over-heating goes, it's an overclocking thing; not underclocking.
My Defy is set at 900Mhz and really, I don't see the point of going much higher: everything runs smooth and lag free already.
vsel: 21/300; 32/600; 43/900 - 90% up_threshold
Been like that for about a month now and never experienced any problem at all.
The underclocking is great for saving battery; no exact numbers to give here but it feels like my battery now last 2 times longer. I can easily get 4 days between charges with low/moderate usage and would get to 6+ days "IF" I could stay away from games and having the screen ON for long sessions of browsing/video watching.
I tried SetCpu before but I didn't like the interface; the simplicity of SetvSel is really nice.
i use setcpu for scaling and profiles, and run 18/300, 36/600, 50/1000 stable and smooth as
Undervolting is not a bad thing at all. It means less Watts consumed for running (Watts = Voltage x Amperage), less of your battery consumed.
Ussually companies test a large batch of components and how they react on different voltages and freqvencies, and then they decide for a voltage that works with all components and that is safe for all cases. Eg. when they have different CPU speeds and thus different options for CPU's this is one way to decide which one work at 3GHz and which one at 2.7 GHz (the other one is demand for components).
Phisically you will not have any problems and you can't damage your phone by undervolting, so no problem here, only possible software problems if you go too low.
Advantages :
+ Lower processor temperature
+ Lower phone temperature
+ Longer battery time
+ Longer components life
Disadvantages
- Stability issues (freeze, artefacts, slowness)

You know, I was recording a video and when playing back noticed that there were squiggly lines that went through the video a couple of times (in a two minute clip). This was the first time I saw this...and have recently lowered vsel by 2 on vsel3...could that be the artifacts that you are mentioning?
I just figured it perhaps I was too bouncy with the phone while recording making it glitch...but now that I see this post I'm thinking maybe I undervolted too much...what do you think?
My settings: 54/1000 44/700 28/300
I know what people mean by same settings don't work for every phone even if it's the exact same model. My Defy won't underclock as much as others. I'm using SetVesel, and I've been able to drop 5 points from each, and that's about it before it reboots itself. I only tested undervolting, but I mainly overclock to get as much speed as I can, and give it enough juice to run super fast. I'm current running [email protected], [email protected], [email protected] Threshold at 75%. The highest the temp ever got was 112F, and that was after playing a game for about an hour. Usually it stays below 90F for normal use. I get around 17-20 hours out of it with screen on time at about 3 hours @ 50% brightness. I've been running these settings about a month, and have not had any issues.
If you put something like 100vsel will the phone accept and then burn? Is there any protection? Does anyone know what's the highest acceptable vsel?
Just for curiosity...
im pretty sure 80 is the highest you should EVER use and that'll significantly increase the chances of your phone burning out. @bobbyphoenix you should be able to lower your vsels a fair bit or your really unlucky! i run a lower vsel for 1ghz than u do for 700mhz smooth and stable

CM7, rather non-technical person here. I seem to have a very happy phone at setvsel settings of [email protected], [email protected], [email protected], 86%. Been running this for the month or so since I rooted and the phone feels like it was made for this config. I've never seen the temp above ~32c. My 2¢.

[Q] Is it really safe to keep overclocking to 1GHz?

I am new to android phones. And i have no experience about overclock.
Will my cpu easily break down due to keep overclocking?..
Honestly, i seldom change my cell phone model, i want my defy can stay a life at least 1.5yr.
i think overclocking can't really damage your phone, voltage can. so i suggest you keep the voltage around [email protected] (default is [email protected], so this should be fine), and if the phone doesn't hang or reboot, you're good to go but you could try lowering vsels, you know, the lower the voltage, the lower the power consumption, the heat and the chance to fry your cpu but i'm not sure!
Yep, 1 GHz is safe, I'm using [email protected] as well, and the CPU is capable to run easily at [email protected] continuously. The leaked Gingerbread ROM from Motorola uses 1GHz as well, so don't worry, you just have to find the safe vsel settings.
thanks for replying, i m currently using 1GHz @ 58 .. Everything is alright
Should I make the voltage as low as possible?
yeah, just to lower the power consumption and temperature, but it isn't necessary.
Can you share your voltage setting please..?
I do the stability test and it gets successful run for 5min then this means the setting is okay?
i don't overclock, just undervolt, here are my settings (with setvsel):
800MHz - 45vsel
600MHz - 30vsel
300MHz - 18vsel
up_threshold: 90%
actually if you wanna make absolutely sure your device is stable, you should run it like for an hour. but if it runs for 5 minutes without error that's quite okay, you shouldn't have problems with those settings
Thanks so much, i m trying to lower my voltage setting.
Besides, i want to ask about the battery temperature, what is the maximum temperature before getting damage to the cell? I usually goes up to 37~39 degree celsius.. is it normal?
mine is usually around 29-32 °C, but i have it undervolted, so idk. but 37-39 seems a bit high, that means the cpu temp is way over 40 degrees, you should check it out!
EDIT: tried stress testing for 20 minutes with [email protected], it went up to 35°C, so you should definitely find out what's wrong with your device!
I actually underclocked to 600MHz, since I couldn't see a big difference even at 1200MHz in normal usage. A Pentium3 at 4Ghz will still not perform as well as a slower clocked new CPU for example, CPU design is more important - what instructions it supports.
Battery life is more imprtant to me and heat is very bad for Li-ion batteries too.
Also I found changing the CPU governor to "interactive" made a difference in GUI responsiveness and I have had less stuttering.

so, what's your standby lifetime after underclocked cpu?
I can see the performance improved when i was watching flash video on browser. But honestly, i dont think there are anymore huge difference after overclocking..
But as the battery life still remains quite well, i will still keep overclocking to 1GHz.. Isn't it a good idea?

lol... What happend to HD and THD games... Did u try playing them at 600mhz??
Overclocking to 1 GHz with the right voltage values seems to be absolutely no problem for Defy.
BTW, does anyone know whether it's possible to set scaling governor to "Interactive" mode under Froyo? Gingerbread kernel let me set it, but I haven't found the way under Froyo.
Battery life was a little bit better, the display and 3G always draw a lot of power.
Standby time got better, but I don't use very low vsel any more due to errors in YouTube and dropped connection of radio streams.
Before I used 300-600-800 at 20-30-48, this was very stable in stability test, but for example Youtube would start showing "error playing video". After I increased vsel, it went away.
I mostly did it to lower temperature, optimal temperature for li-ion is around 25°C according to Wikipedia I think.
I don't play 3d games, they would benefit the most from overclock I believe.
Angry birds RIO for example would stutter for a second or two after a level loaded, but it would become as smooth as at higher clocks, when I wait for a second.
I hope flash gets better, when hardware acceleration gets enabled in Quarx's CM7.
I was running [email protected] for a month straight. No issues at all. The highest my temp reached was 112F after playing games for about an hour straight. I now just run it at [email protected], and it's plenty fast for me. I did some "testing" with all the options in SetVsel. It's not science sound, but if you use the Gingerbread Icon in the notification bar, and are running at stock (800 speed) you will notice when the CPU maxes out it doesn't even reach full capacity. I found Words with Friends to really use the CPU, and at 800 it pings the meter in the orange (The notification icon shows green, orange, and red for "zones"). If I overclock it at 1000 or above then the meter goes into the red. I don't know the exact number it switches from orange to red, but being at stock 800 is well below what the chip can really do since it doesn't even max out the meter. I hope I didn't confuse anyone. It makes sense to me.
weird...my cpu at any game reach the 800mhz
yet even in normal situations like browsing through the files on the phone it reaches 800mhz
and also despite the values i use in setvsel are not high(which is:
24 @ 300
34 @ 600
48 @ 800
)
the phone still reaches maximum 38C when i play games and if i set the value in the third vsel the games starts to hang!!
seems like i am the only one who have these problems..but why
anyone have any idea
im running stock arabic froyo btw
if someone can confirm to me that i can keep Arabic language if i installed another rom using custom restore in nandroid then i would be using prays or official 2.3 but no one answered me about that
anyway the important thing is anyone knows why my cpu temp is always high?
Well ambient temperature is important too. If it is 30°C where you live and your phone's temperature is at 35°C I'd say you are good. If the outside temperature is 10°C and your phone is dat 40°C I'd say there is something wrong (unless you were playing games or watching a movie).
in my opinion, it is definitely safe that you overclocking to the leaked moto level.
however, the voltage is still a mystery.
there's no constant conclusion about this.
i'm using [email protected], [email protected], [email protected], and it works fine for me
I'm getting really annoyed. No problems clocking up to 1100mhz with stock voltage (58). But changing the voltage settings, even slightly, makes the phone more or less unstable.

Overheating Question

Often while playing a game, my screen will randomly dim and i will check the brightness option where it warns me of overheating.
The battery temp is only 42C, and the phone isnt very warm, ive felt phones get way hotter.
Whats wrong? is it the phone? or normal? Anything I can do?
Is ur phone overclocked? Playing game does makes the phone really hot even without OC ur cpu.
Sent from my Galaxy SII √Epic4G Touch
I'm not speaking for everyone certainly but I have seen 42c while talking on the phone.
It does get a bit warm, but I never get the warning you are speaking of. I am completely stock.
I now haven't gotten to this temperature (close but not as high as 42c) in awhile.
My brightness always dims and gets limited to prevent overheating. My phone has gotten up to 125F while it was charging and I was using it (nothing very intensive though, like playing games or anything like that. Mostly texting, email, XDA) I have even had an overheating warning on the charging animation while ordnance few times too. I'm actually going to bring it in for them to look at. I'm stock kernel and rom(just rooted)
Just in a few minutes my screen has been on it just shot from 89.9F to 98F. And all I did was write this post.
Sent from my Samsung Galaxy S II Epic 4G Touch
125F is way too high, there's got to be something wrong with the phone. Mine sits at idle around 70F, with heavy use, it never reaches 100F. And I'm overclocked to 1.4GHZ.

***CRITICAL MASS! ITS GUNNA BLOW!*** hahahaha
It happens only when im playing a game, also at Max brightness. Went up to about 44C. Not overclocked, but undervolted.
Is this abnormal? Should I try to get a replacement?

used to get temps around 115F on my evo 3D,never saw any ill effects though
this samsung does get to 102F or so occasionally,and no ill effects so far either

Well I undervolted, which doesnt make it run hotter, it'll make it cooler if anything.
I've never understood the logic behind that. A processer uses a certain amount of power, measured in Watts. Watts equals current times voltage. If you lower voltage, current has to increase, and more current equals more heat. Am I missing something?

T989 turns off at random times..

hey all, couldnt search forums since its disabled. so like my title says, my phone turns off whenever. the samsung logo comes up and turns off. it happens every so often but nothing annoying. to get it back on is either take battery out or plug to charger and turn it on. when i did this, it gave me the searching for battery thing. this leads me to believe it could be battery? it happens whether the battery is 90% or 20%. anybody have this problem? my phone is rooted using juggs 5.0. phone is just over a month old so wonder if i can get a replacement battery to ruled that one? thanks for the help..
Mines does the same thing except it only reboot when its on charge, and all my contacts dissapear
@OP: Try flashing a different ROM.
Juggernaut has pretty aggressive UVing that not all phones might like.
It happened to me just today. I tried opening Facebook and for whatever reason it FCed. So I reopened it and my phone just turned off. I had to hold the power button for 15 seconds before I felt a vibration and it was alive again. Not sure what the issue is but it's safe to say you're not the only one experiencing this

Random reboots are usually a sign of too aggressive of undervolting. If it's not happening under heavy CPU load and is just happening during standby/sleep phases, then you're just barely on the edge of too much undervolting. Download system tuner from the market and go to voltages in the main menu then knock up the voltage one step (+12.5mV). You should be fine then.
For reference, you can compare your voltages to this list of stock voltages to see what Jugs' global undervolt is. I'm not too familiar with Jugs v5.0:

Are you overclocking? If so what freqs/governor? Mine would do this when I would clock it too high for too long. May be an undervolting problem as well.

Your overclocking issue is actually still an undervolting issue. Your phone would reboot after overclocking for long periods of time because the processor wasn't getting supplied enough voltages for those higher clock speeds.
Undervolting isn't a linear process: if you run a global -50mV undervolt and cap your processor at 1.5Ghz, that doesn't mean that you can run a -50mV undervolt at a 1.8Ghz cap. For example, I'm currently undervolted -112.5mV at 1.35Ghz but if I bump my processor to 1.8Ghz, my phone reboots immediately because -112.5mV for 1.8Ghz is way too big of an undervolt.

Thanks for the clarification. I've not really dabbled in undervolting much, and haven't been too concerned with overclocking since the ol' mt3g days. I'm definitely going to read more about it. I've found that for my s2, stock kernel w/ stock frequency set and governor have worked best. Every device is different they say. Thanks your way for the knowledge. Always appreciated.

xperia play overclock

im now using a custom rom with the overclock kernel... i set my phone to "1.4ghz" with AnTuTu... its working great now... no more fps lags on the games i play... and no crashes... im just curious about one thing? will it break the phone in any way? its not heating up or anything atm... i mean i have experienced phone heat on my sensation xe... that phone gets really hot STOCK....
i dont want to break my play... i really like it compared to other phones in the market right now(the only one with gamepads)... its my first time ocing a phone btw...
If its not noticably hot (the battery too) constantly then your fine, just bare in mind try not to push it past 1.6ghz i found my phone didnt last very long at that speed.
The only thing with oc its that it shortens the life of your cpu obviously depending on how much you oc it....and it drains more battery but its not that big of a deal

what do you mean by it didnt last very long? did it break the phone?
Basically, my phone is overclocked to 2.0 GHz with smartass scaling with max 800MHz interactive scaling when screen turned off. It works great! Lasts 2~3 days without gaming (5 to 7 days with airplane mode on) and 4~8 hours of hardcore gaming with full charge (6~12 with airplane mode on). I recommend using an extended battery (I haven't, yet) if you are doing so. And it also involves luck. Even if it is the same model, color, etc. some CPUs are more capable than others.
still testing my phone under 1.4ghz seems stable...

is it normal for the phone to be abit hotter than when it was running stock???
btw how does smartass compare to ondemand?? smartass tends to get lower benchmark scores than on demand

Yes ofc its normal - as each CPU/GPU creates heat based on the load it takes....
So the higher u OC the hotter it gets - thats why in former days OC was quite dangerous
In todays times cpu normaly 1st get unstable, and then has a safety function to shutdown if it gets too hot. (no warrenty that its the same for all chips)
smartass doesnt switch frequencies at once like on demand (e.g. instant from 200mhz to 1000mhz) but it tries to predict the needed power somehow so the whole switching is done in more steps... (as far as I remember)
So yes its performace is a bit below the on demand - but should not be that noticable - but it will also save your battery.
