Undervolt & Overclocking - XPERIA X8 General

hey guys,
just wanna to find out do undervolting & overclocking really does improve the
battery life & performance ?
Share your comment here thanks!

As for battery life, I've noticed no real difference, no matter the version.
As for performance... it's definitely visible in benchmarks, a bit less in gaming

I did see an improvement in HD games, Verry little or no Lag at all

agreed too that the battery life just same as before >.<
if i did not use overclocking,does the battery life is better ?

i see no difference in battery life in either ways.

I´ve just saw difference while changing use of features like wi-fi, 3G and GPS, Overclock to me doesn´t made any difference on battery life. About UnderVolt I didn´t test any

[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

Excuse me, since when does increasing the clockspeed of your CPU INCREASE battery life?!

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%.

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.

Overclocking

Can over clocking the phone can burn or cause damage to the hardware except excess battery usage and does overclock an 1ghz processor to 1.5 will really give a boost or its just a gimmick
Sent from my Desire HD using XDA App
Excessive overclocking really did damage your hardware, depends on the quality.. Overclocking from 1.0ghz to 1.5ghz really give a performance boost, in benchmarking.. In real life, only noticeable in process hungry apps, such as 3d games.. Gimmick? Well, if its a gimmick, it won't give any sudden resets or lock ups.. The processor have a safety switch if the temperature increase because of oc'ing.. If it's to hardcore, for example, 1.0Ghz to 1.8Ghz or even 2.0Ghz, for sure you processor will overheat and lock ups.
Well, mine running at 1.5Ghz, no lock ups or whatever..

You will barely notice the difference in most circumstances. Even if your phone runs fine at 1.5 or 1.8 ghz it will probably reduce the life of the chip over a prolonged period.

Someone Swyped my idea.
I think it will give minor boost at the cost of burning your hardware

it will help in cpu intensive tasks, that which require lots of calculations, math stuff, 3d drawing done via cpu, faster cpu, better...
in other tasks, don't even bother, there are lots of other things far slower then cpu.
downside, heating, battery drain, increased rate of damage..!
Im using SetCPU for saving battery life. Set the cpu for 384 while screen is off. Noticed quite a difference.
OP, your asking if a overclocked cpu will give a better performance or if it's a gimmick? Really??
Of course it will give you better performance, that goes without saying but the question is, are you willing to sacrifice battery life? The chip will most probably last for years and years if overclocked but 1 thing that kills chips is heat and volts.
I only overclock when I need to and when I'm done I go back to how it was, usually.
My phone is fast enough at 1GHz, dont need overclocking, all games and apps goes fine fine
Most OC kernals are also undervolted anyway so I wouldn't worry about it
to be honest, i use mine with "underclocked" at 800mhz, trying to get at least a half-hour of battery life... i don't see the point in overclock a 1ghz processor, imo, even with a speed gain, the bad side effects easily override the good ones...
i truly believe that overclock my old milestone was the main cause of the problem that happens after...

I'd look at other reasons for your battery life, if it's really that bad.
I'm running at just a touch above 1GHz with no side affects what so ever and get 24+hrs with heavy use, 30+hrs with moderate use and 40+hrs with light use, and that's never turning wifi / 3G off unless I'm in bed when I switch to 2G.
At 1GHz the OCUV kernal I have installed uses less voltage than stock kernal at stock speeds so in theory it's actually safer.
It's not that bad, but it's not so great as yours too. I got about 16hrs with 'hard' use, what is enought most time, but sometimes i get in home with the blinking orange led. Quite annoying...
I try my best to improve the battery life, but i was becoming a battery freak, or something like that, always checking currentwidget...
I get 3 or 4ma at stand by, what is considered normal, i guess... and always use full brightness, hate to use anything bellow...

Full brightness is your problem. I bet it uses like 70% of the current while you use your phone.
going up to 1.8GHz still running stable, thats crazy man!

[Q] Does JIT drain battery ?

Most of the Custom ROMs for our phone now come with JIT enabled. From what i gathered, enabling JIT speeds up our phone response and is reflected in Linpack Score. However, even Linpack score viability in practical usage has been debated by some.
What i wanted to know was whether enabling JIT actually saves battery by making the phone work efficiently or does it drain battery on account of faster performance ?
P.S. - And while devs are at it, could they take a peek at THIS POST ?
JIT does not drain your battery. Theoretically cpu is doing less work because manages the load more efficiently. So that means that maybe with jit is a little better.

I think the post you gave is for HTC Wizard which is a Windows Mobile Phone
Ours is a ANDROID phone
And I agree with LarryMetal that it should be better with JIT enabled...
I wouldn't say that it saves or drains battery.
Just read what JIT-compilation (at Wikipedia - can't post links because I haven't got enough posts) really is and you will understand the differences.
Battery usage is nearly the same as without JIT, but what you get is much more efficient.

If a process completes in less cpu cycles will use less battery. But this is in theory, because in real-life usage of a phone it won't make much a difference, nor in speed or battery usage.
And I know what JIT is, better than what you think!
Thank you for your replies & dharam for suitably pointing out that the hack is WM specific.
So from what i understand, enabling JIT is not as productive as it is made out to be - atleast in practical usage of battery ? Efficiency-wise it does make a difference though? Not a bad trade-off considering that there wont be extra strain on the battery...

Battery Saving Apps (4.0.4 Aurora ICS)

Hi there many of you have thought about battery saving apps.
Do they really work?
Are there some apps that instead of saving battery just drain your battery even more?
Do you know any methods that really save battery?
Just post your oppinions about this subject.

Battery saver apps are useless. just turn of data, sync,WiFi, Bluetooth when not in use. decrease screen brightness and screen timeout to 30 seconds. Use 245-806 with ondemand goveror for better battery.

I've read many people saying that using the ondemand governor wouldnt save that much battery because of the continuous search for cpu activity, actually i'm using performance at 1024 and i also have another profile with 806 performance aswell.
I have to test it better in order to see which governor saves more battery.
I think a good set may useful

I used to use 806 on demand, 1024 ondemand and 1200 ondemand... now I'm using 1024 performance, and I dont see any battery difference.. damn thing still drains.
The battery lasts 4/5 days on idle, what more do you want? It's par for the course.
why do you need the phone to stay on idle? for that you could buy a 10$ one =S

Because it's an indicator of battery performance and proves there's nothing wrong with battery life on Aurora, despite what many believe. Having ~1 day of battery life with heavy usage and 4-5 days (or even more) on idle is on par with the battery specs.

Actually we all know that the battery life in aurora its not full optimized. what i mean is what can we do in order to get the best performance without having to spend so much battery life. maybe its not possible but who knows
Fact: ICS produces more traffic than GB. A lot of apps (like browser) use more memory, so background processes die more quickly. You cannot except to get the same kind of battery performance out of an ICS rom and that's the end of it. This has nothing to do with Aurora.
When I dont need to use the phone I put the governor in powersave with a low Mhz and the battery is more safe with little use.
Phone become a little more slow but work.
When I really need to use the phone I change the governor to Smartessv2

[Q] Power Saving Mode???

Please, does turning off power saving decrease the performance of the note 10.1 2014 edition in any way. And also any difference in battery life? Thanks

It will surely affect the performance of the tablet. I'm not sure about the difference in battery life tho because I also turn power saving mode on
Done some quick tests with and with out power savings mode, in short:
Battery life up 20 % better ( really depends on use and settings like screen brightness and so on)
performance impact , well in reality it seems to scale down cpu/ gpu power buy 60 %, but in real life terms the effect is far from that drastic. Most apps run as fin, no real lag increase, games work just fine, even emulator er ok. You do notice a bit of a lag on certain High rez games , with max quality. But so far Still very playable.
tested with
FPSE (PSX emu)
Need for speed
Bards Tale
Youtube app
VLC ( movie app)
Again these are somewhat subjective tests, and lag is somewhat a subjective element. I haven't done benchmarks and such, simply because benchmark rez don't always translate to real world experience
