Well I downloaded cpu master (free) to just mess around with my photon, and come to find out, the governor for the cpu is set to performance, but gave me the option to change it to powersave, so I switch it and I'll report back to you guys and see if I've found the holy Grail to even better battery life

Wait until I or another dev gets onDemand governor enabled...
I have SetCPU, and honestly, I haven't noticed a huge difference in battery life with powersave unless I seriously scale the CPU back to like 300 mhz. Then it'll last a while, if I don't do ANYTHING with it. For example, when I'm sleeping, otherwise, it just makes the phone laggy and doesn't seem to help enough to make it worth while. Just my opinion from screwing with it.

The general consensus regarding over/underclocking when I had my HTC Hero was that overclocking would save battery because you could get what you wanted done faster. If you scale the CPU back massively while it is set to sleep, however, you will save a lot of battery.

well, i don't know about your phone or what else you have setup, but my phone didn't lag and it seemed to help, i currently have my evo 3d active so my photon just sits there, so i can give a good feedback of idle time, but i can tell you after switching the governor, it went down 1% in 2 hours, now i say that's an improvement, so when i get back home i'll really give you guys some feedback
P.S. with any phone i had that had a fully custom kernal, i always used conservative governor
Well, perhaps it's just the apps I have running then. As I said, when it's set to sleep, it works pretty well with the powersave mode, otherwise, doesn't seem to make any real difference. Guess it's different for everyone cause of the **** they're running on their phone.

You know, I've never bought into this argument. To me, it is like saying that if I drive 100 mph I will get there faster, so I use less gas....which we all know is not how it works.
Maybe the physics are different for processors then they are for engines, but I think there is probably a happy medium somewhere. And I have a feeling that the manufactures really take this into consideration when they develop the kernels and ROMs. However, I might be wrong.
This is by no means an effort to discourage your awesome work. Everyone gets different results, but stock always seems to have the best battery life for me once all the bloat is gone. However, custom kernels do perform better. That is the trade off, in my opinion.

Interesting...I hadn't thought about using an OC kernel and underclocking it back to stock. I wonder what that does, if anything, to performance.
The other concern that I have is that overclocking typically means more heat, which means more battery use... Just figured I would throw that out there too.
well, the results are in, now granted i already had the photon of the charge for more then 24 hours, so at 1d 15hr 57m and 10s i'm at 48%, but from the time i started the cpu test, 1:30pm, it was at 68% so in 8 horus there was only a 20% drop while idle, i say that's a good score , you guys tell me otherwise

Not sure if this will help but let me explain the car analogy. All motors have an effeciency range at x amount of throttle. So same cars will get better gas mileage at a higher speed vs a lower one. Its getting up to that speed where most energy is used.
So let me move this over to electronics. If you run a faster clock speed while on, your apps will open faster so that ia less on time for the screen and other processes that have to run. So using more watts for less time does not always equal more than using less watts for more time. We just need to fill in those blanks and obviously overclocking will not benefit the nook or internet reader as it eould someone who opens a lot of apps for short periods. Same is true for a gamer .
Hope that makes sense and this is all IMHO of course.

Let me start this off by saying that I am an agricultural engineer by trade. With that said, I would agree that engines have an efficiency range. However, I would not agree that it is at x throttle. Rather, it is a x load. And most cars are designed to be at optimal load at about 60 mph (wind resist, weight, etc. play a role in this). You're right, it does require more fuel to get to that speed because the load is higher until that speed is reached. Furthermore, higher speeds (greater than 60 mph) do NOT translate into higher fuel mileages because the load increases to maintain the higher speed (because there is more wind resistance, among other things).
I know a bit about electricity too, but I don't fully understand the physics behind circuit boards. However, I think the analogy still holds. I can get to 60 mph as fast as I want, but the faster I do it the more energy is required. Therefore, even though it is done faster it still requires more energy, which also creates more heat, both of which use the battery. So, I continue to contend that there is a happy medium that most be found and I think electronic engineers aren't to far off.
Here is a little more reading about car efficiency, if you are interested: http://www.mpgforspeed.com/
I believe your confusing overclocking and overvolting. We are putting x volts into the processor so the more cycles we can get in x volts the better. If we have to overvolt to overclock then we see big battery hits.

2cents, that link is interesting but real world examples have proven otherwise to me. Our saab will do better on mpg at 70 to 75 (30 on cruise control) vs 55 to 65(27 to 28 on cruise). Now the wrx is another story as well. With the old 3.9 final drive i would pull in more air at the airflow meter at 65 than i would at 70 with stoich as the target a/f ratio, and because that motor was doing under 2500 rpms the turbo was out of the equation further taking out efficiency with it. Now with the 4.44 and a better 1-2 gear ratio car gets better at the lower engine speeds and accelerates even better and that was before i retuned it.
Another misconception is bigger motors use more gas, one of the recent corvettes get 30 on the highway proving that there is more to this as well.
I think i have taken this off topic enoigh for now. But in general i think my formula still needs to be applied to see the results as a valid number to compare overclocking and underclocking to running stock.

i'm surprised no one even thought of this topic, regardless if things are getting done "faster" you are overclocking the cpu, making it go faster then what it's suppose to, which makes it use more power i.e. more battery, every phone that i had when i overclocked it, the battery wouldn't last too long, even with my 3500mah OG evo, if i overclocked it, i couldn't get a whole day, so underclocking will have the same effect in a sense since the processor now has to work harder to do what it does at it's stock clocked speed, well, hope anything i said here makes any logical sense, but on another note, the photon has gone almost 3 days unplugged!!!
again it depends on how the overclock is achieved. In most cases overclock is achieved by dumping more electricity into the cpu this will impact battery life, however alot of chips these days can be overclocked at the same volts essentially upping the "MPG" or clocks per volt.

I agree with this for the most part. When it comes to power the end result is watts, which is essentially equal to volts x amps. It is not perfect because of a power factor, but it is close. Therefore, if you lower the voltage, the amperage goes up because the same watts are required to run the processor. The inverse is also true. These processors have voltage ranges that they will safely run in, but in the end, they require the same energy (in watts) to function at a given load. Change one a little bit (the voltage for example) and the other (amperage) compensates. Change it a lot and it likely wont work. Again, this is how it works for your typical home appliances. For a circuit board, it might be a slightly different story, but I imagine the science does not change.

You may be right. Perhaps Saab designed their fuel efficiency at 70 mph. It's possible because many speed limits are now at or near that, but in general, optimal fuel consumption is going to be at or near 60 mph. Obviously gear ratios and such play a huge role in fuel economy. It is like using a custom rom, typically your mods will make it perform better, but the best fuel economy or battery life will come with a stock like setup.
Sure a corvette can have HP and economy. There is a power to weight ratio and lots of aerodynamics involved, which again is designed at a specific speed. But there is no way that a dragster will have a good fuel efficiency. To my point, there is a balance...
I agree, we are off topic a little bit, but the conversation is interesting, nonetheless.
By the way, can a mod move this to general, please?
Hey all,
I've been noticing over the past few times I've been playing GTAIII and MC3 that the internal temp of my phone rises drastically, to a point where I can barely hold one side of my phone without having to let go every few seconds because it is so hot. From where the battery is positioned, I assumed it might be the GPU heating up, but other att gsII users said their batteries were heating up.
So,
1) Is anyone else experiencing these problems
2) If you are, has anything happened to your phone
I'm debating whether to trade it in for a new one, because I'm still under warranty.
Welcome to high performance electronics. If you push the CPU/GPU hard it's gonna heat up. It's like a desktop, if you do something CPU/GPU intensive it'll heat up. It's a simple byproduct of inefficiency.
As to batteries heating up, that could just be because they're close to the CPU/GPU. Batteries will warm up under high current draw as well.
Do you have a case on your phone? Those tend to trap heat in as well.

If your phone is overclocked, the processor will be running at the max clock you have set while playing the game, which is higher than what it's supposed to be running at, i.e., the stock clock. Prolonged usage at this higher-than-normal clock will generate excessive heat.

Yeah I don't play GTA3 anymore because of this kind of stuff. It doesn't get to the point where I have to literally move my hands because of the heat though. I simply don't like my phone getting even remotely warm. I'm just really anal about stuff like that. I fear that doing it will shorten the life of the device and I love this phone way too much to let that happen.
I'm sure it's designed to run at these higher temps since mine is completely stock with regards to cpu speed and voltage. If I can't play a game due to this, then I simply pass on the game. Same with my computer but I digress...
Download an app to check the temperature. Yes, ideally cooler the better, but the phone is designed to handle a certain amount of heat.
From what the op is describing, that is definitely too hot. Over time the components life can be shortened. But what you'll see first is your battery life going down, even quit working all together.
Underclock the processor. That can help keep the heat down. Even as low as 500mhz can pay many games. 800mhz should be plenty for most high end games.

download the diagnosis app and set it to check your batt temperature, if that gets above 45c I would be worried and think about underclocking/undervolting.
As long as your phone is cool enough to handle, don't worry. There's a lot more to it, but the electronics can take a lot more than most people credit them for. The battery is the most sensitive to temp, but so long as it's not for terribly long periods of time, you shouldn't even notice any additional degradation over the long run.

Average day to day operating temps are between 30° and 40° celsius.

If anyone's interested, I have pretty much eradicated the heat problem while also boosting battery life and conserving performance. This was done through setCpu: http://forum.xda-developers.com/showthread.php?t=505419
The problem was that apps were just running the processor like crazy on the 1.2 GHz speed setting, and it used a considerable amount of juice that was unnecessary, heating up the battery to a ridiculous amount.
But anyway, here's the profiles/voltage settings I use:
Main Governor: 200 MHz - 1200 MHz on demand
Profiles:
- Charging, 800 max, 200 min, ondemand, priority = 100
- Temp > 44.1 Celsius, 500 max, 200 min, conservative, priority = 100
(this is a conservative temperature, but most place the *dangerous* amount of heat at 50 degrees before battery life starts decreasing, the CPU/GPU components have solder that melts at 70 degrees)
-Screen Off, 500 max, 200 min, conservative, priority = 75
-Battery <25%, 800 max, 200 min, powersave, priority = 75
-In Call, 800 max, 200 min, conservative, priority = 50
Voltages:
(I was able to undervolt by 50-75 mV for each and still remain stable, these are tested btw)
1600 MHz - 1400 mV
1400 MHz - 1225 mV
1200 MHz - 1200 mV
1000 MHz - 1100 mV
800 MHz - 1025 mV
500 MHz - 950 mV
200 MHz - 875 mV
and that's it! It's working great, I don't have the heat issues I used to, now I can play graphically demanding games and the temp doesn't rise past ~42 degrees, pretty solid improvement. I also get 24-28 hours of battery life with 2-2.5 hours of screen on time per day.
No need to worry about this. That's nowaday phones designed to be. Just normal heat.

My S3 heats up really fast when playing Clash of Clans... 5-10 min of gameplay.. and the bottom part of the phones gets really hot... somewhere around 50c or more
i can play other much more resource extensive games like brave frontier or Knight and Squires or sometimes watching movies for hours and the phone barely Heats up
btw.. what's on the bottom part of the phone that's causing the heat ? the ARM SoC ?

It's the CPU, your game is probably coded to use all four cores at the same time -others may only use one.

You're right, whoe SoC is at the bottom, you just have to deal with it, i mean, phones don't have coolers
Also, it's way smaller heating than on S2, it's SoC was at the top by the camera, and the camera cover was metal, and when it heated up it could be so hot it just burned and your finger stuck to it, so, be happy, our S3 is 'cooler' than many other phones (atleast what i know).
Cheers.
Ok thanks guys... wow that 50+ c isn't considered hot

This.
combine that with a badly configured cpu governor that boosts the frequencies to 2+ ghz even for simple tasks that do not need all those cpu cycles.
In addition to the whopping 1.5ghz touchboost frequency (WTF google).
After rooting and fixing the last two points, I experience high temps only when playing games.
Blocking Ads also tremendously helps temps while web browsing.
I wouldn't consider it a problem. I also doubt you have a bad unit even though its getting hot. Chances are if you do the exact same things on 100 nexus 9's the temp will be very close. I've been looking through the kernel code for tegra throttling and doing some tests. The tests show it starts to very lightly throttle starting at 70c in my tests. I believe I saw in the kernel there is 3 throttling states basically, light, heavy, and one other I can't remember. Shutdown occurs at right above 100°c.
As far as the governor, I'm sure if it made sense gooe would have lowered it. But, if I remember right this was part of project butter to make the ui smooth, as well as some other things. I don't think touch boost is killing battery too bad, and I'm willing to sacrifice some for a smoother ui anyway.
Thisbis just a hit running CPU, no way around it and its not a defect, its just a side effect of a powerful CPU in this design. I also noticed although it heats up quick, it cools extrememly fast. Like dropping 15-20° in seconds, literally- so overall I don't think this is a huge problem, but if they can make it better, more power to them.

All phones with good cpu/gpu get hot when gaming for long time.
There is not any thing wrong with that.
Exynos phones get very hot ingame, cpu temp can go up to 70c.
If your note 10 don't get warm after 1h asphalt 8 there is something wrong with it like low fps and or trottle.
Batteri temp in heavy game around 40c
Cpu temp in heavy game (Exynos chip) 60c-70c.
Your phone will be warm..

No.
107 F is too hot*. This isn't a desktop cpu; running an LI battery this hot will greatly diminish its lifespan.
Some of the CPU heat plus the extra current drain heat the LI bat up. I never let my battery temp exceed 103 F when in use or 100 F during a charge. >85 during charging is better.
Put a damp rag around it or on the backside if in use to cool it if the ambient temp is too high...
*43 C is fine for CPU temp as long as the battery isn't getting baked. F is easier for real world temp measurement.
My cpu and chips are running at about 104 F while the battery is at 95F; the ambient temp is about 90 F, acceptable.
This with a light cpu load with brightness at about 40%
For heavy cpu usage at these temps for more than 10 minutes would drive the battery temp unexceptably high without external cooling.
Monitor the battery temp. Lol, if the phone feels very warm/hot it's damp rag or shutdown time.
F is easier for"real world" ? F are only used in ONE country! Which, by no means equals ALL the world, science, real science uses metric system

The hottest my phone has reached playing games was 45°c. But it mostly sits at 43°c when gaming. Is that good?

The Fahrenheit scale is centered around the temperature zone most used by humans.
A 10° F isn't too much a of a change but modest amount.
A 10° C change is huge.
It's ackward to use in real life... suffer.

The heat pipe system in it works very well... this phone should never run hot. If it does, something is wrong.
Mine needed extensive optimization to run cool... it's my favorite phone now. Like having a laptop in my palm. Avoid "upgrading" to Q, it's a nightmare.

All phones with good cpu/gpu get hot when gaming for long time.
There is not any thing wrong with that.
Exynos phones get very hot ingame, cpu temp can go up to 70c.
If your note 10 don't get warm after 1h asphalt 8 there is something wrong with it like low fps and or trottle.
Batteri temp in heavy game around 40c
Cpu temp in heavy game (Exynos chip) 60c-70c.
Your phone will be warm..

No.
107 F is too hot*. This isn't a desktop cpu; running an LI battery this hot will greatly diminish its lifespan.
Some of the CPU heat plus the extra current drain heat the LI bat up. I never let my battery temp exceed 103 F when in use or 100 F during a charge. >85 during charging is better.
Put a damp rag around it or on the backside if in use to cool it if the ambient temp is too high...
*43 C is fine for CPU temp as long as the battery isn't getting baked. F is easier for real world temp measurement.
My cpu and chips are running at about 104 F while the battery is at 95F; the ambient temp is about 90 F, acceptable.
This with a light cpu load with brightness at about 40%
For heavy cpu usage at these temps for more than 10 minutes would drive the battery temp unexceptably high without external cooling.
Monitor the battery temp. Lol, if the phone feels very warm/hot it's damp rag or shutdown time.

Good thing you don't have the Exynos version.
The idle cpu temp is around 50c with about 20-25c room temp.
What program to you monitor cpu and chips with?

122 F is really hot for a cell phone... a very expensive hand warmer. When a phone feels hot; it's already too hot. This will greatly shorten LI life especially if above a 90% charge.
Current drain* at idle with 50% brightness level should be below 220 ma. Typical idle current on this one averages at 140-200 ma.
If it's running >400 ma, something's running in the background sucking the life out of it.
I use different temp apps. Been playing with the Gitlab one.
It's 26.6C (80 F) ambient temp here and the CPU is averaging about 35.5 C (96 F) as I'm using the Note.
Battery temp is the only one I need to really watch.
I monitor that and battery current drain.
*AT&T variat, not rooted but heavily optimized.

exynos is running hot, there is not mutch you can do.
Here is one example
https://m.youtube.com/watch?v=LfZUNL5hyVw
If you pause the video when he start antutu you can se the cpu temp of the s20 ultra (about 56c without any massive load).
My old s8 with exynos got warm and it worked just fine for 2 years, sure i lost a few % on the batteri.
After 2 years just get a new batteri and enjoy.
I know snappdragon is running mutch cooler, but make sure you get a app that show the right temp. 35c in a 26.6C room sounds like idle temp at best.

Meh... I'm liking my Snapdragon a little more.
Samsung design engineers are like a box of rabid gerbils...

For you Fahrenheit may sound "logical" as you grew up with it. For us - the rest of the world - we grew up with Celsius. We don't need a scale "centered around a temp zone used by humans", we know what effect a 10°C drop in temperature has on us...nothing ackward about it.
Yes well...

What do you mean, exactly with"west" ?
There is just one country using that retrograde Farenheit scale, and despite that, scientist there use metric

Unlike the metric system of temperature measurement it is uniquely centered in a range where most living occurs... 96.8° is a better way to index human body temp. One degree matters.
It's Jim Morrison's quote... America, to find yourself.

I think we should leave it, his mind is limited to "west" only and he has not learned to see beyond that.

Update...
Trying out this temp apk:
https://play.google.com/store/apps/details?id=com.novelmatrix.temperaturemonitor
It will display in the corner of the screen real time. Low resource usage. Some ads on set up but liking it so far.
At 96° ambient I'm seeing the CPU, GPU typically going between 102-118 F depending on usage.
Browsing it's running between 100-102 F
Internet vid jumps to about 114 F at this ambient temp.
Obviously higher for cpu/gpu intense apks, haven't benchmark it yet with this running.
The battery is at 96.8 F and typically runs cooler.
The heat pipe seem to work well; dissipates heat rapidly from the cpu and helps keep the battery temp down.
