Can you fry the phone doing so, and is there really much speed increase?
I still havent fried my G1, im running the latest sensehero and using bill cui overclock widget. I did notice a little change in speed
My phone has been overclocked for about 11 months.
Nuff said.
It's physically impossible for apps changing the clock speed to damage the phone because they don't clock the chip faster than it's advertised speed or change the voltage. The chip is factory clocked at ~175mhz to save battery life, so the chip is simply re-clocked to 528MHz (which it can run at all the time with no problems).
does overclocking kill the battery faster?
Yes (10 char)
I use set cpu for overclocking. It has nice exceptions list for better battery life
it cant fry your CPU because your never actually over clocking it, the CPU max is 528Mhz.... so your just clocking it, but by the time your CPU is done on your phone you will probably have smashed the screen or dropped it in water or gotten a nexus one so it wont have any real affect on your phone
Hi guys,
What is safe Tegra 3 temperature? I tried SetCPU stability test for 20 minutes at 1.6GHz and System Tuner Pro showed 72C. I'm correct, 80C is bad? I also suppose SetCPU stability test is more aggressive, than games or any other apps.
I user to run v10a firmware which often ran to 80° with no ill effects. I would be concerned if it rose any higher. The phone is built to shut down at 90° so I wouldn't worry too much, it can handle the heat

i had my device shut down twice while running werewolf with no skin throttle. i put the shutdown temp at 80 degs celsius. this happened after an hour of gaming. so yeah, it could probably run even more. i think default nvidia's shutdown temp is 120(!) degs celsius. not sure where i read it though.
I have throttle set to 75 and shutdown to 85. This is more than enough for me.
I wouldn't let my device go anywhere higher than 80C... It might be able to handle more than 80, but I'm not willing to risk it

I saw it from a kernel's changelog (don't remember the kernel's name), it said in the changelog "Tegra 3 default safe temperature : 85 C"
but I wouldn't recommend going above 80 C, it would reduce lifespan of your phone, not even mentioning the battery.Since battery is pretty close to tegra 3 chip, it gets effected by the heat chip generates
The main problem with high temperatures is not the chipset-temperature but the battery shouldn't get too hot. Li-batteries will be destroyed on high temperature. It's around 50 °C.
Did you hear about bloated or exploded phone batteries? This were cases of high temperatures.

Strange thing. Hot in the SoC area (top), not at all where battery is.

Because it is actually the SoC what gets hot. Look at temperatures in Trickster mod (or any similar app).
Better be careful, be careful burned out CPU

It's just one thing - Tegra 3 chip is awful. I watched a lot of review of Optimus 4X HD, but not in one was talked about awesome hot, sadly. Though Tegra 5 are looking very nice now with Kepler GPU, but I'm furious on nVidia and when I will buy phone next year, it not will be powered by nVidia chip. I'm crossing fingers on next gen Intel Atom SoC.
What's the lowest has anyone been able to under volt the Moto X? I just tried -75 mV set globally and I haven't had any bad experiences so far.
My question is why? Not many reports of overheating on the X and that's all undervolting is good for?
You won't notice any battery life increase. That's a nasty myth.
I'm at -125mv for 384 and -100mv for 486. Then 50 or 75 for the remainder. Have noticed absolutely no battery life difference. I'd be careful with -75 with overclocked frequencies if you're using faux ultimate kernel. I can't do more than-25mv at 1.944.

your statement is a myth. it doesn't improve dramatically but nonetheless it helps. when I undervolt I am more looking for my CPU to stay cooler these add longevity and not letting the battery heat up as much. out of all my undervolted phones, there was a noticeable improvement on my galaxy nexus with battery life and heat. my note3 isn't dramatic, but I do notice my phone rarely gets above warm now. and depending on the bin of your chip, your undervolt can have more desirable effects if you have a great bin. my moto x had a 3 out 4 bin but I never flashed a custom kernel. my HTC one m8 has a bin of 9 out of 16. decent. but the guys who 13 and 15 bins should get great undervolt. undervolting is worth it. adds longevity to the battery itself the less it heats up.

Pretty sure I mentioned it keeps heat down.
And I could have posted a huge long reply the first time....but "generally", undervolting to improve battery life is barking up the wrong tree. YES it should have minor improvement....but not anywhere near what some people hope when they do it.
At best you may gain a couple total hours and maybe 20, 30 minutes screen time.....if you tweak other kernel settings as well??? Hopefully we can agree on that. And to me, the possible instability from guys pushing the limits is not at all worth those small battery savings.
As far as longevity of the battery.....all I know is my oldest device is 3 years old...and battery life is as good as it was when I got it. But sure, it might help.
Heavy gamers or anyone with heat issues....yes....undervolting will help.
Guys with "bad" battery life.....you will at best go from "bad" to "still pretty bad".
Hey guys,
can you share your CPU stats - usage and temperature? ~45* and 21% on 1300MHz seems weird to me, especially I only used a launcher and a browser. Note is in a Protective Cover, but I don't think it should make any significant difference in temp. Maybe I'm wrong or these temp and usage are quite normal? (phone is new and I still have a few days to return it in a bad case, that's why I'm so curious)
If i'm not wrong, Cpu Spy app only shows A53 Cluster's frequency.
Try using CPU-Z or AIDA.

A53 cores run on 1300 mhz basically whenever you touch the screen. But you can also experiencing fingerprint problem.
Ok, but what with temp? Now I'm jumping between Chrome, Messenger and FB and temperature is ~55-60*C. My hand feels that pretty well...
I bought a Note 9 last month and I am noticing the idle temps are around 34-35°C. I live in a hot country where the avarage ambient temps whole year are around 33°C. With moderate, non gaming, work the temp goes to even 42°C. God knows how high it will go if I gamed.
I have found some people saying that anything above 30°C will lessen the lifespan of the battery. So I am bit worried after paying a lot for the phone I wont be able to use it even 2 years. I aim to use this phone for 3-4 years.
I was under the impression that Note 9 had some water/carbon cooling system, which seems to be useless here. Are these temps normal? Should I be worried? Will it have some long term effect? Are there any tips to make battery cooler?
I used Accubattery for these temp readings.
I wouldn't think 35°C is too hot.
No.matter what claims Samsung make for their improved cooling the ambient temperature is always going to effect the battery and cpu temperatures.
Whether we're discussing cooling a phone or a vehicle engine unless using some kind of refrigeration the coolest temperature is going to be above ambient temperature, so higher ambient temperature will cause higher internal temperature.
I wouldn't think it will have a significant detrimental effect on battery life although as you state gaming or other high power usage such as Sat nav is obviously going to push the temperature higher, I expect battery and soc management will keep things in check if temperatures get too high.
I wouldn't be worried about battery life unless sustained temperature of in excess of 45°C.
Lower temperature does tend to benefit battery life a little, ideally around 20°C should give optimum battery life in terms of charging cycles.
My advice would be enjoy using your phone, don't worry.

Thx for the reply, I don't game much so thats not a problem, I have noticed phone does get hot when using GPS which I have to do more frequently to navigate; but I am in the car in AC, so I think it would be manageable.

just the sun hitting it can push the temp. but it might simply be a rogue app or something.
if freshly resettedþfactory wiped its under 30c, you know it was an app that you installed that caused it.
