[Q] Real world noticeable benefits of Over clocking G2?

Hey,
So I'm on the fence about perma rooting and over clocking my G2, but i have a few questions:
1) Will my battery life suffer greatly due to over clocking say to 1Ghz or 1.4Ghz?
2) Are there any real world noticeable real world performance gains besides benchmark scores?
3) Will perma-Rooting it decrease performance? (Back when i had the mytouch 3g, the phone never felt as snappy after i rooted and installed custom roms, as compared to stock).
Thanks

1) battery life is the same if not better when overclocked with setcpu in ondemand mode at 245/1100mhz
2) there is a definite performance increase
3) custom roms can decrease performance depending on the rom and ui (sense is a bit heavy). Just simply rooting will not decrease performance. Also, CM6.1 is super snappy, especially using Launcher42
DO IT!

Launcher42? that's a heck lot of upgrade from Launcher2 I'd like to check it out
but he's right overclocking is not going to eat up your battery much. Heavy graphic ROMs do however suck up battery and performance. I personally like to stick to rooted stock roms and tune up here and there to fit my personal needs.
You should however read carefully and make sure to understand every steps you're doing if you want to root your phone.

Alright I'm going to give it a shot later tonight probably, i forgot about the SETCPU profiles where you can have the phone under clocked while the screen is off. That should definitely give me better battery life. Ill be back to post results

Good luck and I'm sure you will enjoy your G2.
Oh, and don't forget to show it off to your friends. Let them see how this thing "Fly"

I oc to 1.4+ with setcpu and a few profiles set up i get much better bat life then stock. Im also running a sense rom which feels sluggish until you oc. At 1.4 it runs smooth as can be with live wallpapers plus all the pretty sense animations. The only problem i have is i hate the sense dialer and msg system also i want to change the "personalise" tab....do people really change theyre settings everyday that they need a dedicated button for it? Anyway i digress

No, that's not entirely true BUT with SetCPU you can profile it with different mode which can benefit the battery life.

I don't notice any difference in battery and I have the 1.9ghz kernel. I normally keep it at 1ghz though. I enjoy it overclocked. My games run incredibly smooth, when navigating my phone it literally almost feels like it knows what i'm pressing a split second before i do and benchmarks rape the face off anyone else I know with an android phone. It's just sooo smooth. It really boils down to being the kind of person who likes to hold a powerhouse of a phone in the palm of their hand. (Literally) with even just the 1.4ghz OC you'll never have to ask yourself "can my phone run this without being sluggish?" because the answer is yes, it can probably even run two or three instances of whatever made you question yourself in the first place without being sluggish. Any if you're worried about custom roms from the past, just remember how outdated your old android is compared to this one. No offense because I can relate, I used to have a G1 that is now a hand-me-down to my brother and whenever he asks me to mod something on it, I'm just amazed at how slow it is and really don't know how I tolerated it for the last 2 years. I mean I'd score a 150 quadrant on the G1 (on a good day) but with my full OC on, the G2 scores 3000~3100. That's roughly 20 times faster...
Bottom line is that you won't need to worry about "will this make my device sluggish?" for quite some time.

Hey
Alright guys i got the phone perma rooted now, but i havent installed an OC kernel yet, two questions.
-Which kernal should i install if i want 1.4Ghz? there seems to be two threads with 1.4ghz kernels
-Do i need to install Bacon Bits for the kernel?

just install cm6.1 and setCPU and you will be fine, then you can tweak it up to 1.42 if you like or whatever you want it at

Any heat related issues? Let's say I get into a zone and play some graphics intensive game 6 hours straight on USB power at 1.4Ghz? Wouldn't that put out more heat then the G2 was design to handle possibly shortening its life span?

It doesn't. However, overclocking is misnomer. What we really mean is over and UNDER clocking. For example with SetCPU is can create a profile that greatly slows down my CPU when the screen is off. This saves the battery a lot, since my screen is nearly always off.
Also, I can create profiles that slow down the CPU as the battery lowers in order to offset the fact that I overclock the CPU when the battery is fuller.

Probably could shorten the life span. I keep phones for a year or two, though, and shortened life span for me isn't an issue. The phone becomes outdated before the CPU gives up.

^This.
I've gone a full 10 hours with my battery still reporting 100%.
Sent from my HTC Vision using XDA App

my default sense rom does not feel sluggish at all.
this oc is not really required from my point of view. and it also does not increase battery. the thing what increased is the underclocking when screen is off.
and this you can do even without overclocking. and THEN it brings even more gain.

an example of "real world" for me is how well my g2 plays PSX games on the emulator. I have it overclocked at 1.5 on setcpu and it runs chrono cross pretty much flawlessly with no noticeable slow down.

i use setcpu for underclocking since i don't do enough just yet to overclock, i haven't noticed any battery increase just yet and i've been using it for a few days now. i almost questioned my self if i was losing battery life due to my system mhz always fluctuating? is this a possibility? i just added a profile for screen off 245/245 but i still had to choose on demand? what should i put there. thanks for ur help everyone

I installed the bacon bits 1.4ghz kernel and setup some setcpu profiles.....battery life is much better now.

[INFO] Custom Kernels & Overclocking - FuguMod Ultra Pre Release

After reading through the Thread for the Pre Release of FuguMod Ultra in the development section of this forum I thought I would post some info up for people who are wondering why it doesn't work with their phone, and just some general info on overclocking.
- First off, not all phones will be able to run at 1366MHz. Every CPU made has a range of freuqencies it will work at, and it is different for every single one. So some may be able to handle 1366MHz and above, others may max out at 900MHz. If you are getting black screens, freezes, or random behaviour, then your CPU doesn't like the frequency you have it at, try a lower frequency.
- Always keep an eye on the temp of the CPU when testing overclocking, if the CPU gets too hot, and fail safes don't work, there is a chance you could fry your CPU.
- With the FuguMod Ultra kernel, you must also be aware that gpu bus frequencies have been changed, so if your phone is not happy with that it will black screen. (as bus speeds are like cpu speeds, every different device can handle different clock speeds)
- plls values have been changed, and these may cause problems on your phone.
So if you want to have a go at overclocking your phone, back it up, and then give it a go. Select a frequency, and test with something pretty cpu intensive (3d game, multiple quadrant passes) and see if there are any bugs/overheating during a 15min time period. If you notice any problems/too much heat, try a lower frequency, and try again. And if for some reason your phone doesn't like the kernel, you can reflash with your previous kernel or a new ROM as you have already backed up your data.
If you have any other questions about overclocking, feel free to post here and I will try my best to answer them.

How can you check the CPU temperature? I thought it was only battery temperature.

The battery temp is a good representation of how hot the processor is getting as it is right next to the battery (only a thin sheet of metal seperating it) If the battery rises in temperature by a few degrees, then you can summize that the cpu is probably getting a few degrees hotter than that. I really wouldn't recommend letting the battery get above 55degrees (celcius) as this means the CPU may be getting up close to 65degrees (celcius) which is a very bad thing.

Good post.
Note that if you want to make some stress-tests, you have to put "PERFORMANCE" governor and set the max freq you want to test.

How have you got your phone set up? i.e. what ROM are you using etc.

I am using stock jpq with app2sd, swap, zipalign, ramhack and stuff. Setcpu is installed with default min/max freakquency, No profiles in use and undervolt a bit.

Ok,
This may be an issue caused by XXJPQ, as it is a new release there may be some sort of conflict. Have you tried asking if anyone else has this issue in this thread? http://forum.xda-developers.com/showthread.php?t=1132697
I haven't played around with JPQ yet so don't know what the bugs are yet.
Also, are you running a stock kernel? Have you confirmed that the phone has been rooted properly as well?

It's definitely a bug in Kernel. I tried three different roms and i wasn't able to check time in state in any of them (I am talking about fugumod ultra prerelease kernel here).
With previous versions of fugumad kernel everything is fine. So definatly a bug in kernel.

Ok cool, I'll report the bug to the developer so that he can have a look into it. Thanks for testing and proving to the kernel.

Little bit of info some might find helpful. After some recent testing, I have found that some people might experience a black screen freeze when phone is in standby for a while with 83MHz min setting and on demand governor. I am not sure of the exact reason for this, whether it is a bug, or that the processor just doesn't like going that low for extended periods of time. If you experience this type of error, just hard reset the phone then open setcpu after phone has loaded and change the "standby" profile minimum to at least the next step up on the slider. Personally I use 223 setting as it provides a smoother lock screen animation, and no significant difference in battery drain.

[Q] setcpu and evo battery life

hi
i have a htc evo 4g running android 2.3.5 and kernel 2.6.35.10-g4b48446 [email protected] #1 and i have a few questions on setcpu. its a stock rom and it is rooted.
I shut off my profiles and disabled the perflock - it said success. So i ran the long bench test and only got 2078 ms, not 5000. so i dont know if its really working. I reengaged the profiles and i think it works with the screen off. the rest of the time i am not so sure. in fact it seems to still drain fairly rapidly unless i turn on some battery saver or something. I have the following settings on my profile all are set to ondemand except charging which is set to performance. the only other setting i can choose is user
in call 998 max and 245 min priority 91
screen off 384 max and 245 min priority 88
charging any 998 max and 245 min priority 85
battery <25% 460 max 245 min priority 81
bbattery <50% 883 max 245 min priority 65
Temp> 42 C 614 max 245 min priority 50
what am i doing wrong? I have it enabled and i have notifications off
i have system panel to try and monitor but its not recording and it also drains the battery like crazy so i think thats set wrong as well but i dont know why.
i also tried juice defender but it doesnt work right because it says the AOSP file isnt found in the system/app folder. I looked there and also in teh data/app folder and its not there. So i dont know what to do about that.
thanks

stock sense is just not all that efficient really. (well thats my opinion) profiles seem to look ok but also finding a different kernel with different governors (smartass v2 is rather efficient and changing around the frequencies as needed)
auto sync settings as well? turning some stuff of that you dont use or look at and so on can help too
and calibrating battery a bit can help aka a full discharge a full charge and full discharge will sure help (also what i have found personally)

kernels
thanks for the reply. You mentioned different kernels. I understand about rooting my phone but not so much about how to load a different kernel or different rom. Where do i go to learn about that?

look around in the development section as there are some great kernels available right now...Ca1ne just released a new version of the underworld SBC v6 that i personally like with great battery life ...Mason kernels are also great with great battery...just make sure u read the threads completely to make sure u are using the right kernel for the rom u are using...ie there are kernels for ics...sense....and so on......also the kernels load through recovery...just load kernel to sd and wipe cashe and dalvik and flash zip...hope this helps...Carp

Hi another question about kernels. I am a bit of a newbie other than rooting my phone so i want to understand what advantages/disadvantages different kernels have. You mentioned smartassv2. i have seen others like
chopsuey kernal
freedom kernel
golden monkey kernel
savaged-zen kernel
tiamat kernel
all of these i think support sense roms.
as i understand it , you have to go into the recovery screen and load hte zip file off the sd card and reboot with the new kernel. What are the risks/rewards of doing so? I guess i am trying to understand which one would suit me best.
i have the current sprint lovers rom i guess since it is factory stock so should i also be considering changing the rom? Maybe i am getting ahead of myself here.
thank you again.

which rom are u wanting to run....this will help us steer u in the right direction
im sorry your entire post didnt load on my end i see ur running sprint stock....that is a fine rom but i have not ran it myself....
---------- Post added at 01:53 AM ---------- Previous post was at 01:36 AM ----------
i personally have switched to sbc kernels when they came out with a sense version...i am addicted to sense 3.5...just my personal likings...sbc is superior battery charging whichcarp will give u better full charge on your battery so when the light turns green and u unplug it it wont drop down to like 90% battery in just a few mins....i can squeeze another couple hours out of my battery with sbc and even more depending on light usage....but u will stil need to play around with different cpu speeds like 786..921 and so on to see what your individual evo can stand....what works for 1 may or will not work for another....lags and bootloops etc...

You don't need to change Roms, you can if you want, but changing kernels will unleash new features. Some features are:
Full hdmi mirroring
The ability to over/under clock CPU
2 way call recording
Improve battery charging
Enable swap space
Improved performance of phone
Some kernels allow under volting CPU to further save battery (this can cause some stability issues so start slow with undervolting)
You may want to take a look at Lionfish kernel also, just note first boot may take a while.
Also ditch the profiles in set CPU, I tried profiles and it never seemed to work right. A good governor will handle all your profile settings.
I like smartass, and intellidemand the most on my set up.
As an idea ok the battery life I am getting, I streamed Pandora over 3g for about 8 hours not much other phone use, screen off most of the time, and my phone was at like 20 %. I thought that was pretty good.

thanks detcup4evr for helping out explaining that better...i blew out my back and between no sleep and pain meds the brain just dont want to fire...thanks for stepping in bro....carp

smartassV2 vs InteractiveX ... which one giver better performance AND battery life??? currently I am running LIONFISH 1.8 with interactive X

Using profiles in setcpu actually uses more battery life. Because it has to be running all the time and monitoring phone state to know when to change to a different profile.
interactiveX vs smartassv2 all depends on how you use the phone and really which kernel it is. I've noticed little things like on mason's I got better battery with smartassv2 but on other kernels I get better battery with interactiveX. As far as performance, you won't realize a difference.

ok so it sounds like i should try the sbc sense 3.5 kernel with the smartassv2 governor. Did i get that right? i will look around to see where i can download that.

Were you refering to this kernel?
Underworld Sense Kernel v0.6

yes this is the kernel i run with ODJDub HD Bliss!! Sense 3.5...if u choose to run this rom it will give u alot of different options of kernels and apps and other things from the installer....if i can help u more just feel glad to hit me up....carp

Ok so with lionfish 1.8 kernel and interactivex, I should not use a profile? What does CPU go to on screen off? also where does it mention profiles use battery? I'd like to read more into this..

Sense rom with Underworld v 0.6
At Carp -
thank you for the advice. I was thinking maybe i would use my ROM still (its a sense i believe) and load the underworld v0.6 kernel with sbc and see how that goes. I havent done very much research on ROMs so i dont know that i want to get that deep into this just yet. It seems like underworld has alot of nice features. One thing that i am wonderig though is with the new kernel would have any further ability to unload some of the sprint bloatware or do i need a new rom to do that or is there another way to do it? Things like qik video , gmail, accuweather blockbuster etc all load themselves periodically. I kill them but then they come back like weeds. Even programs i do like , like pandora, wheres my droid etc come back also. But i dont want them to.

no u will be fine getting rid of apps and bloatware u dont wont...u wont need a special rom....i use a free app in the market called root uninstaller to get rid of useless bloatware,apps etc...then u can go in and manually uninstall what u don't want...be careful not to uninstall anything which the phone needs to boot and operate such as android system...you will see the things u are looking for when u load the app...hope this helps...carp

I actually did something unusual.
I have universal aggressive lionfish SBC 1.8, swagged out stock N, and smartassv2
I set the ideal, sleep, and wake freq for smartass v2 to 128, while setting the up rate to 245. I used set cpu to lower the min freq for my device to 128. I set max load to 100, and min load to 85, and down time to 0. I then set a profile for "ondemand" during screen off, of 128-384.
I actually have pretty awesome battery life (I'm an uber heavy user).
Sometimes it reads that I spend over 70% of my time at 128mhz.
I feel no lag. It clocks to 998mhz maybe 15% of the time, mainly when loading web pages.

flashed underworld v 0.6
Hi Carp,
well, i flashed the underworld v 0.6. So i see in set cpu that i can underclock to 128 and overclock to 1228. however, i slid the slider over to 1228 by accident and it froze the phone even though it says its still at 998 mhz. then it rebooted by itself. so i guess that wasnt a good idea. Anyway, theres a ton of governor choices now in the profiles section. i am not familiar with alot of them but i was wondering which of those would provide the most benefit. they are as follows -
ondemandx
interactive x
intellidemand
smartass
interactive
conservative
smartass 2v2
performance
along with ondemand and user space from before.
thanks

Good to hear....u will need to try different settings as each evo will be a little different...ie.. some can take alot of overclock and as u said when u went to high it locked up......my evo likes min 245 and i dont go very little over 998...mine does not like high overclock....i run between 768 and 998 or until i can see a lag or slow down in performance..depends on which rom i am running...i like ondemand x and smartass 2 on my evo but there is a good read in papa smurph's smurphed out v6.6 thread in development on governors and such...go to post #2....i wish there was a perfect setting i could give u but u will have to see what your evo can take...part of the fun of android.....carp

Governors
Thanks carp. I guess experimentation is the only way to know. i charged my phone last night ad i noticed that it does take alot longer to go from 100% charge to 90% but i also noticed that the phone temp was at like 110 deg F and a voltage around 4.263 or so. i have read some thread where they claim its bad for the Lithium ion batt to be over 4.2 V but as soon as i unplug it it drops to 4.1 something usually. I am using battery indicator app to measure it. i am using the underworld w/sbc kernal currently but the voltage being higher has me a bit concerned that i am damaging the battery kind of like pumping water into a jar with the the lid on tight til it bursts. Or in the batteries case - too hot i guess or until it plates.

Mahdi ROM Kernel Tweaker & Battery Life Thread

Hey guys.
I have a clean Mahdi ROM (the latest from like 1 week ago) and have the feeling that the battery drains slightly faster than in stock. Apart from other things I started trying different kernel tweaks and I discovered the following:
The governor, although showing explanations for a whole 7 different modes, only allows me to either pick "interactive" or "performance".
Since I never really need the CPU settings from interactive mode, I actually want to use conservative.
How can I realise that now?
Please feel free to post your battery life stats, I'm really curious.
Sidenote: I have "transparent weather clock" on my homescreen and it seems to need a lot of battery. Does anyone have a recommendation for a lightweight & goodlooking homescreen widget?

The kernel for that ROM only contains two governors, please do not use performance because it only uses your max frequency, which is bad for temp & battery life.

Ok, thanks for the info. I wondern why it only contains those two though.
I'd never use performance, interactive already provides more power than I need.
I'm just looking for a way to actually use the conservative mode.

Something weird just happened to me: my phone was at about 38% and when I looked 1h later, it was pretty warm and powered off 1min later because battery had dropped to 1%.
I think this is pretty weird. I did not use the phone in that hour and had no apps running.
As illogical it might sound, my first suspect was the energy saving mode I enabled. I dont know why but I think it messed something up.
Does anyone have similar issues or any useful advice for me?

The developer believes those to be the best choices, I have no clue why. Interactive mostly stays near the max freq & makes my phone uber hot like an oven. Feel free to use Render kernel, its in the general section.

Speed and Battery tweaks.

So I've been following this section for months and just got my a2017u 2 weeks ago. I'm rooted with tenfars tool still locked on b20. I've noticed in the last few weeks a tapering off of new and useful info for this phone and would really like to see what and where everyone is with it? LSpeed? Kernel Auditor? Or any tweaks that have helped either performance or battery life!!! Looking for anything to make this already great phone better!!! TIA

I have been using EX Kernel manager to tweak the settings as kernel auditor was not working properly with the big.LITTLE arrangement. I have upped the readahead value and underclocked the cpu to 1036mhz on the little cores and 1401 mhz on the big cores. working still as snappy and getting +2h SOT. I'm a heavy gamer and Asphalt 8 still plays as fluid as before, even better tbh due to less heating.
If you don't like to underclock, you could try these:

+2h? That's really good! I know overclocking can/could/might damage the CPU. Does underclocking have any of the same risks? I'm rooted and unlocked atm. So no warrenty anyway

Overclocking can't really harm anything. The excess heat might but it would take a long time and really high temps (you couldn't keep the device in your hands). The only thing you risk by overclocking is a system crash. Just reboot, lower the clock values and voilà ! So no, underclocking can't hurt anything. Overvolting however poses a real threat to the integrity of the components. It's quite the same thing as in computers (except for the heat, you don't always realize it's too hot in a computer).
That being said, is overclocking still even possible on smartphones nowadays ? Just for the fun of it because it's not needed in the least on the Axon 7 .
That's impressive results ! Not sure those hours are needed since the battery is doing well with the software power saver but still a good thing to know.

Still any extra sot is welcome. I'm not a gamer, don't really have any apps that truly need the full power of the sd820 so might give it a shot. Greenify does wonders for standby time.
Not sure if the built in 'intelligent country control' does anything tbh

I'm on my phone most of the day whether it be YouTube play music, texts,calls,etc.. I'm just hoping to find a balance between battery and my multitasking ADHD LOL

Mine keeps switching back to 'normal' modes with CPU full on. Any idea how to fix that?

Yup, I had that problem too initially.
First, I made system changes persistent upon reboot by running this command in Terminal emulator(you can also use adb shell):
reboot disemmcwp
Secondly, you have to disable smart power in the quick toggles.
Once this is done, set your new max values, select the arrow next to it to make it applied on every boot and then reboot your device. It should work.
Note: Everytime you open the EX Kernel manager you will see the speeds jump to max for like 1 sec but if you actually check the cpu statistics you'll see that your settings are sticking and the max clock speed was just for everytime you open the app.

The smart power! I forgot that thing controls the CPU.
So that round arrow thing means apply on boot? I selected that, figured it meant something like that.
Cheers!
