can changing cpu speed decrease phone life?

I just downloaded setcpu and as I was setting the profiles, I wondered if the frequent changing of CPU speeds could damage anything. For example, when the screen turns off, I set the speed to a low value, because I won't be using anything at that point. But when I start using the phone, it scales up to a bit higher speed. When the phone is charging, its at max speed, 995mhz. When the battery drops below 20%, the speed drops really low to conserve battery. Will these different scale values damage anything?

under clocking the phone will not have near the possibility of damaging the processor as over clocking. The main thing to worry about is the thermal specification of the processor. If you ride that limit too long, or surpass it, then you risk greatly reducing the life of your phone. But under clocking as in your case does not normally present that same form of danger.

bravo bravo!! /clap
if only we could install a xigmatek dark knight cooler on this thing. we could oc to 3ghz lol

LG G4 heating

Hi,
How much does your LG G4 heats up? is it constantly warm even with low-moderate use?
Please share your experiences so far!

Mine idles around 30C, hits maybe 35 under heavy CPU load, and gets up to 40-45 while charging (especially when using the fast charger). It's warm enough that I put a small fan in front of it while it charges (heat is bad for batteries) but otherwise I don't really notice. This is Canadian model (H812), rooted and XPosed, but no mods to thermal systems.

Mine (LG H815-AR) does not seem to overheat on idle or charging but when I play a game it heats a little bit. Specially on Smash Hit, that does not runs smoothly as it should (a slight frame by frame lag sometimes). That is incredible, on my LG G2 Smash Hit was a real Hit! No heat and no lag at all... Software update needed or Qualcomm problem?

mine gets to 42-45 when playing (pretty fast) , usual is 30-34 . living in a hot country though

Mine is @30-35 in idle, in games (Dungeon Keeper in particular) can get to 60-65 which is hot, but nothing to worry about...

I had same issue, so after trying all the available internet fixes including factory reset, I decided to mail to LG, PFB their reply (guess heating up is just fine unless you want to burn your skin )
-----------Reply to Customer Enquiry------------
Dear Customer,
Your phone is an electronic device that generates heat during normal operation. Extremely prolonged, direct skin contact in the absence of adequate ventilation may result in discomfort. Therefore, use care when handling your phone during or immediately after operation.
If your phone sometimes heats up than usual, there isn’t cause for concern since the device is functioning normally. For example, your phone may get warm when you’re using on Wifi Or Unstable 3G network Connection.
The Reasons why your device may get warm are
(a)Playing videos, games, or other media apps.
(b)Tethering your device or using it as a Wi-Fi hotspot.
(c)Using the phone while it’s charging.
(d)Downloading or uploading a lot of data over 3G or Wi-Fi connection.
The Ways to prevent your device from heating up are
(A)Keep your phone away from direct heat or excessive sunlight.
(B)Avoid keeping your phone in enclosed or poorly ventilated areas where heat can easily build up.
(C)Don’t use a case or cover that isn’t made for device .
Or
(A)Try by Simply closing the applications that are running in background
(B)Pause resource-intensive features or apps until your phone cools down.
Your phone is an electronic device that generates heat during normal operation.The actual reason for this concern is the extremely high resolution LCD used in this phone.
The Quad HD IPS display provides with four times the pixels of HD with a superior pixel density. You can see sharp, detailed imagery on screen with an advanced pixel structure that provides a near infinite contrast of deep blacks and bright whites as well as more accurate color reproduction.
Due to this Quad HD LCD, battery drainage will be more as compared to other models & hence battery backup will be lesser & due to high data processing , more heat will be generated.
Higher resolution results in increased data processing and speed of GPU, CPU, DDR memory and etc. All of these factor in power consumption increases the temperature of device also.
This heating is absolutely normal & will cause no damage to the phone.
Also The phone has a inbuilt thermal protection, which reduces the CPU usage, brightness etc when the temperature increases.
Do register on their site and ask them all the queries to be sure its not a defective piece. Mine seems to get fine with the day by day usage, not sure why though
Regards
SK

In Taiwan, someone used this way to preventing the heating:
link.
But I used closing 2 cpu core to prevent it, because the warranty...

I used to do that disabled 2 Big Core and or lower clock to 1.5Ghz.
But since I installed CTT Mod....I don't have to do that. Its Run Cool.

Are these temperatures normal?

I've had my M5 (E5603) for about a month now and my CPU temp peaks at around 60-70°C (140-158°F) according CPU Monitor during heavy use (eg. intense gaming or extensive 4K UHD recording). Not once has my device thrown a warning at me or shut down, nor has the performance been affected in any way. During normal use, temperature stays somewhere between 40-55°C (104-131°F). Battery temperature always stays below 40°C (104°F).
So, I was wondering, are these temperatures normal? Could any harm befall on my device? Besides being a tad bit too hot to hold on the back and also the front, it doesn't seem to be causing any problems.

Anybody?

Yes these temperatures are normal. Don't worry.
If cpu temperature is above 65 celcius it is little bit not good. Temperatures of cpu between 55-65 celcius perfectly normal for a waterproof phone.
Don't worry.
M4 aqua heated to 65-80 celcius in it's intial firmware.
This forced sony to release the m5 to cover up the problem in the m4 aqua. ? ? ?
So overheating fixed on m5.

Basically, this is why it is waterproof, so you gotta put it inside water to get colder
(as I have fount everything is normal)

Normal temperature range for OP3

What are the normal temperature for oneplus 3, when playing games, using fb,messsenger,whatsapp in 4g and watching video and doing all the same activities in an ambent temperature of 29

I don't think many people actually measure temps of their phones ... Suffice to say - it can get pretty warm, but not too hot (maybe max around 45°C on surface). Internal (cpu) I guess could easily achieve 70+.
P.S.: Stop being so paranoid! This is at least third thread you opened about temperatures and people keep telling you that your phone is NOT overheating ...

This is the reason
I posted a pic using cpu Z... It was when I was uploading a video in Instagram.... See sensors Reaching 50-55???
I was tethering and using Instagram.. Is this normal for this

With light usage i get about 30°c and on heavy load the cpu goes up to 70°c, those temps are pretty normal

FFS it's a metal backed device which conducts heat but also passively cools faster. Devices are getting very powerful. I came from a Z3+ which hit 80-90 °c on the soc. This device is no where near being "hot" and that's from running consistent synthetic benchmarks and gets to 50°c but cooled very fast.
If it hits 80°c + on the Soc not the individual cores as they ramp up and down very fast then maybe you can repost.

Holy crap I'm tired of this... Those sensors are for the CPU, the CPU throttles at 85°C and here you are asking us the same question in which we've already answered you.. THERE IS NO PROBLEM with your phone. Now stop asking these questions and stop being so freakin paranoid. It's hot outside your phone will get hot.

Question Heating up from basic usage

Is it normal for this device to heat up from basic usage (such as browsering and social media).
By heat I do not mean overheating but it does make the hand feel quite warm.
This worries me alot since I get annoyed by phones who get hot with basic usage.
Would this be because of the sd870 chip?

For me it does warm up a little bit during normal use but it's way better than my previous phones, idk maybe my standards of phone temperature is different than y'all. And if it was running a SD888 it would be even worse.

I think mayb the issue is me comparing it to a snapdragon 730g

This was my concern also but in my case hearing was mostly during charging. I replaced the device and so far things are a tad bit better

Charging especially fast charging produce heat.
Charging is an electrochemical reaction that requires a certain amount of heat to charge properly. Oddly Li charging is a mildly endothermic reaction but resistive elements in the cell produce much more heat than is absorbed.
♤Do not use phone while charging as it will skew the charging curve.
♤Listeners to music (no internet streaming) on bt with screen off is generally ok.
Best start temperature for fast charging is 82°F or higher (85-90°F seems optimum on my N10+).
Do not let battery temperature exceed about 101°F while charging, cool as needed.
♤I use a fan and/or a damp microfiber cloth to keep it cool, works well.
Li plating will permanently degrade your battery and can cause outright failures.
Never charge a Li polymer that is near freezing temperatures.
Charging below 72°F or in high temperatures (exact value unknown, some say >140°F but this may not apply to Li polymer) My Note 10+ will stop charging at about 102°F so hence the 100°F limit. In any case temperatures higher than 90°F aren't needed for fast/optimum charging and only shorten the lifespan of the battery.

Nope, miui is chock full of bloatware and make these phone warm up even some basic task. Tried several custom room in our forum, no heat up at all

I think it has to do since its summer too, debloated through but it still gets warm using social if I'm outside or if its under the sun.
From my logic this has 100% to do with a higher end cpu since as I said my sister samsung a71 does not do that.
Mostly worried that the xiomi build quality is **** that's why I asked

Use manual brightness control. Try to avoid going over 50%... and don't use in direct sunlight. High screen brightness increases current drain/heat a noticeable amount.

You're on to something when it comes to brightness... Newer panels that are being used in the latest Chinese devices all have very high sustained brightness. Which is nice and all but no1 had considered how that will play in combination with the newest chips,
If you compare F2 and F3 the earlier model only had sustained brightness of 500cd/m2 whereas the newer model can sustain 900cd/m2 of brightness - that's a huge difference
Then what about chips? Both snapdragon 888 and 870 are dumpster fires ( Even the dimensity chips ) , while the performance gain is insane compared to last gen so is the heat output... And sadly even the gaming devices with cooling fans struggle to keep the chips from throttling. Take black magic 6 pro for a shameless example (snap 888), it reaches upwards of 55C on the phone body itself during benchmarking with no signs or intention for throttling down to save your hands- that itself should be illegal but no1 ****ing cares since how else are they gonna reach those benchmark numbers.... ( 54C can cause full thickness burns in a matter of 30 seconds or so )
I don't have poco f3 to check but from looking at stress tests on YouTube you can see that they are much more conservative when it comes to heat. It reaches only 42C during benchmarking then starts to throttle down and basically hovers around that temp 42C-44C.
The chips are already insanely good when it comes to performance but the cooling is pacing behind... So yeah it's pretty normal that your device is getting hot - so is every other device on the flagship market rn. Most you can do to solve that would be in this order > Get a peltier cooling device like blackshark fun cooler pro > Lower the brightness to what's usable for you and hope it's enough to somewhat delay the throttling > The last one would be messing with the phone itself like downclocking it or lowering the voltage. It's a cat and mouse game , the throttling will come eventually , the only way out I see would be the first option or the last one if you're capable enough to mess with that and are lucky enough to get a chip that undervolts nicely.

Cooling?
Simply use a damp microfiber cloth.
