[Q] Optimum "LOW" setting for performance based overclocking

I am loving my Android experience so far coming from and iPhone 4. I am running LeeDroid and have been playing around a lot with SetCPU. At this time, I am not concerned about battery as of yet. I am asking this question in regard to optimal, blazing fast performance with minimal hiccups.
I have done Quadrant testing at various min/max CPU levels. I had excellent results at 1804 high 904 min. However I had to yank the battery after not being able to unlock the device.
For profiles, real basic, again I am not concerned about battery charge life ATM. I have it set to revert to stock performace (1036/245) if the battery temp reaches 100F.
With the screen locked, I have it set to 499/245. All of my settings are using the "ondemand".
I would like to know what an ideal minimum is for PERFORMANCE as well as ideal max (1804? Highest might not always be fastest?). I got amazing results with Quadrant full benchmark with settings of 1804/499. This also caused a lockup when trying to unlock the device though. Maybe because there was a conflict with my lockscreen max setting? I would think the app would put priority to the lock profile though.
Also, does this phone have a built in CPU temperature sensor that I could utilize with a CPU temp widget?
Thanks for reading my lengthy ramblings.

Thanks for your excellent A, B, C format response. I'll head elsewhere.

What temperatures are acceptable for overclocking?

My sensation is currently overclocked at 1.73ghz, and according to a temperature widget I have it seems to hover between 25-45 degrees. I can only find the one temperature reading, so I think this will be the battery temp. I've set setCPU up to run at 1.73ghz below 35 degrees, then come down to 1.5ghz above it. If it gets to 50 degrees, it's then set to drop to absolute minimum and play a warning sound. I've also set it to drop to minimum when the screen is off to save power if the phone doesn't sleep, and to not exceed 1.2ghz when on charge or during a call. None of them are fixed, they're set to intellidemand or whatever it's called.
Do these settings sound reasonable? What sort of temps would be deemed as normal? I don't want to shorten the life of the phone if I can help it.
Also, if this temperature reading is just for the battery, what would I need to monitor CPU temperature too? Is there an app available so I can actually log the temps to see what happens when playing games, etc?

Cheers, I'll give it a try.
What sort of temperatures are acceptable before I risk the CPU's lifespan?

Why do you need these over clock speeds? They will only ultimately increase temp, burn excessive battery and reduce the life span of your device.
Use common sense, these speeds are only worth using for bench mark tests
Personally anything above 43 is to hot for my device, although not same as yours, you can use set CPU to throttle down at this temp

I mainly wanted to overclock since the normal sensation was underclocked in the first place, the sensation xe runs at 1.5ghz and the CPU is the same. So I wanted at least that. What I'm wanting to do now is find how quick it can be before it starts running too hot. Just wondering what's considered too hot in the first place.
Sent from my HTC sensation using Tapatalk

My web browsing is much better (faster and smoother) at higher clockspeeds and performance governor. So that's why I run higher speeds. I use my phone for internet stuff more than anything else.
matt

Mine seemed smoother too, for normal use and for my emulators. I found a problem though, setCPU wouldn't let the phone sleep so my battery went from 85% to dead overnight! It also seemed a little unstable even when turned back down to 1.53ghz, so I've uninstalled it and it's now running 1.53ghz just from the kernel. Runs perfectly now and battery life is back to normal. No noticeable difference in performance going from 1.73ghz down to 1.53ghz either, but now the battery temp seems to top out at 35-40 degrees or so, so about 5-10 degrees less than when it was set higher. I'll still give that app a go though so it can monitor and log temps while I'm playing games, etc.

Q)? Pyroice kernels

I saw. 3 kernel.
Slightly. Uv
Midle. Uv
Extremely. Uv
What are the differences. Between. Those. ????
Sent from my myTouch_4G_Slide using xda premium

Saw that too - exciting!
UV is undervolt, which means running the device with less voltage (electricity). Uses less juice, battery lasts longer, and doesn't run as hot.
Depending on what you do with the device and how it's implemented the results could range from awesome battery savings without a reduction in performance to brownouts and having the processor work harder to get the same job done.
If you do a lot of processor intensive stuff ( resource heavy games, for example ) undervolting becomes a harder thing to take advantage of because the processor has to work harder when it gets maxed out.
The fact that tbalden lifted the artificially low 1.2 clock speed and bumped it up to it's rated 1.5 offsets that somewhat.
For most people undervolting is a godsend, because they don't miss that top % of maxed out processor performance.
Also, the greater range of speeds allows you to regulate the speeds of the device using apps (setcpu maybe) which can't set speeds outside of the range the kernel allows.
Tbalden got into what I was trying to before my crazy work schedule hit, and he is doing a whole lot for this device - now I'll be following the trail he's blazing instead of the other way around - win for the MT4GS community when people have time to make fun stuff like this for us to play with.
Haven't had the chance to read up on what he's done with it other then seeing it was there, so this is some general info to get you started with, there's a lot more to be said and I'm sure others will swing by and add to this description.
Sent from my Bulletproof_Doubleshot using xda premium

Slight is slightly undervolted, meaning it saves less on battery
Middle is around 5% undervolted, meaning around 5% saving in battery drainage
Extremely is 8%
Depending on the quality of your cpu material, it can work on your CPU well, or if it is made of a silicium chip that is less clean then your CPU will say voltage is too low, and phone might reboot. So depending on your device it may or may not work out.
UVing the cpu means no performance decrease. You should find out which kernel is best for your device. Safe is to go from Slight to Middle and then to Extreme if the Middle works out well. If you have reboots, fall back this way: Extreme --> Middle --> Slight
Also, if you dont want to use the Overclock frequency range, use SetCPU or an alternative cpu tool to cap it to your like.

Thanks guy. Now I understad why my phone s batt last longer . I flashed the extremely kernel . And I'm using an anker batt. And adding profiles with set cpu
And I noticed. My battery. Last way longer then before . Even though. I set the main profile of the set cpu to 1.5 hz max. 1.0 hz min. Wich makes the phone run as. My loptop. . Thank u developers

Best battery Saver

Idk if this goes in Q/A or not I never had a Q/A section as I came from the amaze but anyway. What battery savers do you guys find best? I Use Batter Defender but doesn't seem to really extend it. Would i be better of not using one at all?

I use 3 programs to help me maximize my battery life.
1) Badass Battery Monitor to figure out what's sucking juice, how long I've left, and how long until I'm full.
2) 2x Battery to manage background data. This probably saves me the most battery by disabling that data transfer a lot of the time.
3) Lux Auto Brightness to tweak my screen brightness. It's pretty much on "dark" now all the time aside for when I'm in really bright light.

JuiceDefender
I use the free version and it's very good!

I think the most effective battery saver is to flash a kernel that has become voltage control features and undervolt the cpu.

I'm not a fan of under volting the CPU. Mainly because if my understanding of Ohms Law is correct, it's pointless. And my personal experience with it seems to corroborate my feelings.
Under volting the CPU in my experience just introduces stability and reliability issues. I've personally never seen any battery savings from it, especially since the CPU should, theoretically, just draw more current (I) to compensate for the lower voltage (E). It's watts (P = ExI) that matter, and the CPU, if I understand correctly, is going to demand the necessary P for the frequency requested. So under volting either starves the CPU (it can't get enough P), or over currents it (it draws more I to compensate for less E). There are slight variations in each CPU, obviously, which may allow for a margin of under volting to be possible without issue, but the battery savings of this, I feel, are so small, any you notice are most likely a placebo effect. Your screen, and apps constantly polling the CPU or network are your biggest source of battery drain to worry about IMHO.

I use Power Controls widget.
Unless I'm actively using internet, I make sure to turn 4G data to 2G. That alone saves so much battery. If I want further battery saved, I disable internet completely with a touch of a widget. Now my phone will last a week just by what phones do best: Making phonecalls and texting.

I'm on 2.1 GHz overclock processor and when battery goes below 30% it goes to 1ghz I can see the battery being saved

With an higher frequency the phone will use more power, like a pc processor when you overclock it so this is natural, but overclocking/downclocking has nothing to do with undervolting, MadJoe is right.
With JuiceDefender for example you can set your 3g/4g to shut off when you don't use the phone, it activates 3g/4g when you use your phone and at regular intervals in backgroud so it can fetch emails etc.
All automatic so you don't have to switch off and back on network connection every time.
As network connection is one of the services that consumes the battery a lot this is really effective and really improves battery life!

I've read a lot of complaints about these PowerManagement Apps using more battery life then they safe.
I don't know if this is right.
At the moment I'm running CM9 with modified auto-brightness options, auto-sync and 2G/3G/WIFI always on.
I'm really happy with the battery life I get, so I don't see why you would need a Battery Saver app with this phone.

Tips for Best Battery

So guys, its a fact we have a small battery for our phone but I was wondering, how do you get the best battery life?
Just post anything! What ROM your using, what kernel, your kernel settings or maybe a tweak you found.
I want this to become a help center for people who suffer from bad battery
EDIT: Also, have you guys expierenced a difference with unfervolting?
-Sugardaddy

Try Greenify in the Play Store. It seems to help for me.

I use a Tasker profile that will disable mobile data when my screen is off and when it's not being used. Don't know if it helps or not I don't worry about battery because I have a a portable battery pack charger thing

Pretty sure there is already one of these.
Elementalx kernel, greenify to hibernate Google maps, use WiFi as much as possible.

I wholeheartedly believe in Greenify! I have it on my tablet and phone. I've seen a jump in battery life by about 30% since installing it. Not sure if you will have the same type of luck or not.

There's many factors that can be affecting your battery. More importantly it depends on the type of rom you are using, assuming it's sense based... Try using elementalx 6.6 kernel, it'll help your battery; tweaked with the right settings. Power saver also seems to help a bit.

This probably isn't what you had in mind but my best tip is to keep my old iPhone with me and use it for media consumption. That way my android always has a full battery for actual getting work done.

I've noticed on CleanRom that maps uses a lot of battery %. I've never looked into it, but I'm guessing you've found the same problem.

Why not just Greenify maps as suggested by others. Did wonders for my battery life, used to go to 15% in the evening, now regularly above 60%. I also use autostarts to kill some other processes that are launched by default

I'm using the stock Android 4.1.1 ROM unrooted. With my normal usage, I can get through two full days. I make sure to toggle off WiFi and mobile data when not in use, as well as toggle on the "battery saver" built into Sense. I also turn off sync for everything (Facebook, Twitter, etc) except for two Gmail accounts which only check for email. It's about on par with my old Nexus One that I moved from. Keep in mind, however, that I just got the phone and these might change, but this is what I've noticed thus far.

A combination of 2xBattery (toggles data connections when screen off) Tasker (toggle data in different times/locations) and Greenify.

When it comes to battery life, the basics really are the most important.
here's a couple:
1. Don't use auto brightness. It tends to keep the display super bright even when it's not needed. The display may very well be the component that draws the most power in the entire phone! Look for widgets that let you select manually (I use "Brightness widget - backlight" from Google Play and even manually, I set the brightest it can go to 79%) or apps that still let you have auto brightness but more controlled (Try "Yet another auto brightness" from Play Store).
2. Use a setup as stock as possible. I know some people are going to disagree with me , but having your phone as close to stock as possible will have the best proven battery life. I think some of the developers here do amazing work on custom roms and kernels, but when people report good battery life you should keep in mind that are so many factors involved that it's hard to replicate it if you want to. Carriers test their phones extensively to ensure good battery life, and while I am NOT saying custom roms and kernels is a bad idea, I AM saying that I believe a stock experience is a more proven option.
3. It also has been proven that undervolting does NOT help with battery life because not only the difference in millivolts is negligible, it may cause instability and finally a reboot, which just happens to be the biggest software-related power drainer.
Hope this helps

im running clearrom 6.5 but i havnt been able to get greenify to work really. when i install it, it only shows a couple apps that i dont really use to begin with. correct me if i am mistaken, but greenify will hibernate/shut off running apps and the apps that the greenify app shows are apps that are currently running?

Correct. If the app you want to hibernate isnt running you would have to run it to add it to the hibernate list.

I don't know if I agree 100% on that one. Undervolting can reduce the amount of heat discharge caused by too much voltage being provided. A hot battery affects battery life both in the short term, and the long term.
Yes, not all phones can handle undervolting (because they're already receiving a good amount of voltage out of the box), and will glitch and reboot, which drains battery.
But, for phones like mine (which I can generally UV by about -75mv without adverse effects), the reduction in heat can only be a good thing for my battery life.
Sent from my Evita using XDA Premium

Heat itself should not cause your battery to drain quicker. Heat is moreso an effect from the cause of something causing the battery to drain rather than heat causing the battery to drain faster. Heat can damage the battery which would cause it to drain faster... so what I mean to say is heat will often accompany the battery draining quickly but not be the cause of it. Hopefully this post makes sense.
Sent from my HTC One X using xda app-developers app

Yeah it's the damage caused by heat that I was talking about. I've heard a hot battery will discharge quicker though. But heat is also a side-effect of the battery providing the CPU with too much voltage, that extra voltage being provided has nowhere to go so that energy ends being dispersed in the form of heat. Which in turn damages the battery.

That is mostly incorrect. The voltage options we can tweak are not enough to make such a big difference, so you can and will still experience heat even with an undervolted cpu, provided the load is the same. And that's my point, that the difference in undervolting in millivolts is negligible yet one reboot can wipe out an entire day's worth of battery life "savings" from an undervolted CPU.

Ok well all I can say is UV'ing definitely decreases heat for me, particularly when playing games (which is when it heats up the most), and I can safely operate without reboots. Before you say it's a placebo effect, I check my temp regularly to verify it.
