How safe is overclocking and how does it affect battery life.

Hey there people. I'll be receiving my artemis tomorrow and I would like to get the most out of it. I allready decided on what rom I am going to use. but I want to know how safe is overclocking. I want my artemis to be able to watch movies without to many trouble. I want to play some games (Age of empires, myst, some of those games) and more. I am willing to charge my artemis every night as long as I can do the entertainment as much as I want
So advice please people. To what could I safely overclock and how long will my battery last then?

Mines currently overclocked to 286MHz and has been since I had it (over 8 months usage now). The battery lasts for well over 4 days without a charge with moderate usage but obviously the more calls etc then the quicker it'll go down. Its device dependent but mine physically won't overclok any higher. If I try then it immediately freezes but 286 is spot on with no issues at all. I've known others who couldn't go quite as high but like I've said previously, it depends on your device so give it a bash.

Yeah but it won't be wise to blow my mobile up the first day

Nobody will tell you what is "safe CPU frequency" for overclocking, but I never heard about Artemis owner who damaged device by going to far. I tried about 270 MHz with my PDA for long time, with higher freq. I had to soft reset device, one even hard reset was necessary, but after that everything was working OK. Remember not to set overclocking after reset
Regarding battery drain - I didn't made tests, but with BatteryStatus and "on-demand" overclocking I noticed no big difference - when you play game CPU is oveclocked, but then it may by underclocked.

How safe is overclocking and how does it affect battery life
Hi,
a popular formula to calculate the dynamic power consuption of CMOS ICs is:
P = (1/2)*C*V^2*f (C - Capacitance, V - Supply Voltage, f - Frequency)
As you can see, the frequency is a linear factor in this equation. So if you double the clock frequency, the power dissipation will also double. But the processor does only has a portion of the total power dissipation of your device. So the battery "life time" will not be doubled.
If you choose a frequency that is to high, the device will not work correctly -> bit-errors -> Softreset. This is not serious, but my concern about extreme overclocking are the extrem temperature cycles -> produces a mechanical mismatch -> mechanical failure inside the processor package or printed circuit board. But this is a long term process.
Kind regards,

Power Saving Mode and High Performance Mode

How much is the cpu downclocked to on power saving mode?(not extreme power saving mode)
What's the high performance mode clocked to? Does the battern drain notably quicker. In a couple hours? Is it possible to keep it on high performance mode always or does the battery life shorten so much that the phone won't be practically usable?

Power saver, not sure, however the device I'd noticeably slower and the battery life is noticeably better. High performance mode as far as I remember keeps the cpu at max.

Oh odd, I read on the android forums that the high performance mode over clocks it to 2.8ghz. I can find the post for the life of me but I remember seeing the posting date in May so it could be old/wrong info.
As soon as I opened the developer settings, and didn't mess with anything, the phone started acting up so I'm afraid to open then developer settings again. Even though I did not touch anything it may have done something else, my phone was mega buggy.

High performance mode does not overclock the CPU and it doesn not keep the CPU at max. It just makes the CPU ramp up clockspeed more aggressively under load.

Htc 10 poor performance

Hello, my htc 10 is lagging in games like hearthstone ,csr 2 and generally all graphical intensive games. I dont know what to do,i even used the high performance mode in the developer options but it doesnt seem to do anything.isnt this phone supposed to not lag at all?what should i do?

1) Check if you got any app that hogs your cpu in the background. CPU hogs = more heat = more throttling = lagging.
2) Check if you've put your phone into a thick case, some of these cases will negatively affect the rate of heat dissipation.
3) If you are 100% sure none of the above is the issue, you might have a lower-tier-binning chip (which means to achieve the same frequency, your chip have to run at higher voltage, hence more heat). Then, wait for some guru to make a custom kernel that supports undervolting. No guarantee though, neither on such kernel being made nor your undervolting potential.
4) Try some custom kernel like this one from flar, which do loosen the thermal limit. http://forum.xda-developers.com/htc-10/development/kernel-elementalx-htc10-0-01-t3385167

I have no performance issues running any game.
Have you tried running the games in Boost+?

CPU Thottling?

Does the Samsung Galaxy Note10+ (Snapdragon) throttle the CPU to save battery life or manage heat? If so, is there some way to modify that?

Of course there would be a way of doing it, but first root must be achieved

i believe so i keep it on high performance mode at all times

I've only seen this happen if you have either of the power saving moves enabled.

I ran a test with the device set to high performance mode, and there is definitely some modest throttling after the 2 minute mark. Root can't come soon enough.

So you want it to overheat instead of slow down? Damn thing says 174 degrees.

Can someone, who has the Exynos version, do the CPU Throttling Test and share the picture, please?

The only rootless setting you can set for it is the moderate power save that fix it to 70%
You need root otherwise.

Every CPU have Throttling. This is about temp. increasing. Have one test in GSMARENA.COM
Flagships vs Gaming phones. After 1 hour hard gaming casual flagships decreasing CPU power on 60, 70 % to prevent overheating. In Gamer phones like ROG or Black Shark decreasing is only around 90%. This is because they have active cooling systems.

I agree. But not only gaming devices. For example, Sony Xperia XZ Premium doesn't throttle that much.
I just wanted to see if there is a difference in Throttle on Exynos and Snapdragon.
If someone could do a CPU Throttling Test on Exynos, I would be very happy!

Exynos is horrendous. Just look at gips. Im starting to believe more and more there's something wrong with my device.

Multitasking/RAM

You're busy and don't have time to wait, which is why you need to stop reading this thread and get back to organizing your Pogs. Rate this thread to express how the OnePlus 8 performs when multitasking. A higher rating indicates that the OnePlus 8 keeps many apps in memory so that they don't need to reload, and that when moving between apps, transitions are smooth and performance is excellent.
Then, drop a comment if you have anything to add!

DDR4X (not DDR4)

In case anyone views this thread and wonders what I was wondering when I saw it, which is: "What the hell is the difference between DDR4 & DDR4X?"
DDR4X has a higher maximum clock speed at 4266 Mbps (DDR4 maxes out at 3200Mbps) aka your phone feels faster as the instructions stored in RAM are more rapidly accessed
Lower power consumption, a rather dramatic reduction from 1.12V in the case of DDR4 with DDR4x operating with only 0.61V of power, which translates into longer battery life under load.
