Im not sure if this is normal but the cpu temperature after like 5 mins of use always goes up to 30 degrees is this normal? I'm not overclocking and not doign much but you can feel that the battery gets real warm...
Do you guys experience the same?
CPU temperature of what device?
30C is low or normal for most PCs, and though I am not sure about mobile devices in some parts of the world it is room temperature this time of year.
For a better (more specific) answer please write what device you are measuring the temperature for and what software you are using to do it.
P.S.
The feel of the battery has nothing to do with CPU temperature. They often get warm specially while charging.
On my prophet, if I charge it, OC it and use all the radios (Bluetooth,wifi) and do processor intensive stuff like watching a video, battery status tells me it's at about 40... I haven't noticed any damage, but I only do things like this very occasionally. I don't think it should be a problem although if the battery gets too hot it will degrade.
allright im using htc p4350 Herald and I'm measuring with battery status pro...
But it might just be fine if l3v5y says somethin about 40 degrees...
I would try and keep the temp down as it will last longer running cooler, but I don't think it will impact too heavily.
i did not see a topic about VERY slow charging and hot phone issue
first of all, typically for 10% it takes me 3 hours to fully charge my GS2, and it is warm but not hot
randomly it seems to get a bug that makes the phone charge VERY slow like 15% an hour or total 6 hours, and at the same time the phone is much hotter than normal charging
i had Android Assistant running and here is what is normal idle system spec:
CPU
system 2%
user 5%
idle 93%
ram
used 329MB
free 507MB
battery temp 97F
when the bug occurs i go to the stock task manager, close all apps, and clear ram memory, and here are the system specs after:
CPU
system 20%
user 40%
idle 40%
ram
used 460MB
free 377MB
battery temp 114F
i have not been able to isolate the process/app/bug anyone else?
I use Watchover (freely available on the market), which can give you a list of processes and the percentage of CPU they use. You can then identify the processes that eat the most of your CPU.
It's not a bug but a feature
The phone takes about 3 hours to charge when no apps are running.
More, if apps are running and even more if you are using the phone.
Totally normal for this type of phone/battery.
So if you want it to charge as quickly as possible make sure as little as possible is taking power....

but i stop all APPs in task manager and even clear my ram cache, so technically it should be like idle with nothing running
and yet it shows 60% CPU usage and 100MB or ram used somewhere, no idea where

OS Monitor from market to check what is eating the cpu.

Doesn't clicking on battery usage show the same thing.
Do the other apps do something different.

this shows total usage between 100% charges of battery, so what might be the highest CPU % usage might not be what is currently stuck in a feedback loop
i want to see what process or app is "stuck" in a loop or on cycle that is causing the slow charging and hot phone bug
when i stop all apps in task manager and clear ram (which usually kills 19 processes in the background) i should be at 90%+ idle
i need an app that can show me a snapshot of what is running on demand and doesn't show what was running before but was stopped
What does the battery usage screen tell you? After trying to charge, unplug the phone and leave it for 30 minutes. Then open up the battery usage page and check which item is consuming battery power.
my phone was getting hot when i was using custom kernel and had overclocked
check your kernel first

OS Monitor will tell you in real time which process is using up CPU cycles. However, battery usage shows you which app/process is using up the battery, which is what is happening to your phone. It is using up battery charge as fast as the charger is able to charge it. So check out which app has the highest percentage battery usage. If it is Android OS, then you will have to use OS monitor to dig deeper to pin point which Android OS process (there are many) is causing this.
so i identified the problem!
it is HANDCENT SMS (MEDIUM) WIDGET even though i do not have that widget loaded on any of my home screens
this gets somehow bugged and starts to use 30-40% CPU real time, and even after i force-close the process it comes right back in a few seconds
i have uninstalled HANDCENT SMS and my idle is back to 90%
i bet if you have the SLOW CHARGING HOT PHONE bug it is because of this widely popular SMS app, i am going to try GO SMS instead
Hi. I searched the forum for this problem. Just got an GSII three days ago. Experienced this a problem few minutes ago. Started charging my phone when I got home. It was at 36% at 46deg c. Then I talked to my friend on the phone. Checked back 30 mins later and it was at 33% at 53 deg c. It was the hottest the phone was ever. I panicked and unplugged it and shut the phone down. Turned it on 5 mins later and I just plugged it now.
Is my unit faulty?

EDIT: It's back to charging normally now. Temp at a stable 46deg c.
When I didn't rooted my phone, I also was experiencing overheating. Once I´ve rooted the phone and undervolted the phone and used kernel from Solarflare. Since then my phone didn´t overheat.
I wish we had a cpu temp reading as well as the battery temp one, I suppose the cpu usage will have to do, I think most overheating and slow charging is caused by power being used my the cpu as you charge the battery, some fault apps in conjunction with the heat of the battery produces when charging, really starts to heat things up.

I was just going to point this out as well. The same is true for a laptop. Recharging the laptop with the laptop power off will still generate some heat near the battery, but the moment you turn it on and start checking email, watching youtube, and doing all kinds of other stuff, core temps are going to be higher than usual as the battery charging heat adds on to it. So, I wouldn't be overly concerned with the overheating part just as long as it on a open surface like your desk and not wrapped up in a blanket on your bed.
With regards to the slow charging, that will directly be related to how much you use the phone, number of currently running apps, and number of background apps running (syncing, etc). I strongly suggest putting the display brightness level to lowest setting when at home while charging since this is the single largest consumer (50%) of battery power compared to anything else for me. If you do find that there are some less responsive apps stealing cpu cycles when it shouldn't, then I would consider uninstalling it altogether as it probably is also reducing your battery life during the day.
Thanks for the replies. I know the SII has a tendency to work up some heat and I'm just worried about damaging the internals. Does anyone know though what the maximum operating temperature is? So I could monitor my phone or turn it off when it reaches a certain temperature. I tried contacting Samsung about this but they didn't reply (their CS is bad in my country).

same thing, i kinda worried with the internal parts, if it going too hot every time. Even only using wifi for browsing, it made a heat that really annoying

Yeah. I'd really like to know if it's okay that it gets hot a lot and at what temperature the internals get toasted. The manual says nothing about it.

I would say 46c when charging is way too hot, Im even finding 41c already above the expected charging temperatures.
I have noticed Kernels having a lot to do with strange battery drain and overheating. I flashed back to a stock Australian Carrier Firmware and as soon as my phone restarted it was getting hot. I could feel it burning through the back and front of the phone. I flashed another kernel and the problem went away.
I am using G2 F320L. It is very good set. but i have problem that its battery temperature rises up to 45 degree Celsius (centigrade)!
When temp rises, it can observed physically (handset feels hot on palm).
Please tell what is upper safe limit for battery temperature?

Probably that's a reasonable limit - from own experience I have to tell you that if the phone stays hot for a long time you may damage the screen (yellow spots), so try to keep it cool somehow if you are doing CPU heavy things - for example, when flashing it, I keep it on a pack of cheese from my fridge. It works though :silly:
Back on the HTC one x the battery to be classed as over heating with 48c.
So anything under 50 is OK, though I wouldn't want to sit up st that limit for long periods of time.
I've never seen the battery get about 45, and considering I've seen my CPU get up to 92C (at which it turns off the phone) I say its a safe temp.
Just to clarify my phone didn't do that on its own the default is to throttle and keep the CPU below 75. I turned that off and sat my phone on a fan to see what I could push kitkat too in antutu.

Thanks for useful info!
Now i concluded from above comments that temp under 50 centigrade is ok but not for longer time!
Hello, what is the normal temperature for s8 when not using and when actively using it? Mine is around 30 degrees when I unlock it after not using for 10-15 minutes, and 35-37 when actively using (music, browser, etc). Is that ok?
First of all what is your ambient temperature? Secondly is this your CPU temp or batt. temp? Under heavy load CPU can go up to 70-90C before it starts throttling, battery shouldn't go much above 40-45C, but if you live in Las Vegas or Phoenix, this is how hot it gets outside, so phone will reach those temp even when shutdown, if you leave it outside.

Thank you foe explaining, Battery temperature is 37 when I amactively using phone. I live in Moscow, right now we have around 5 degrees Celsius. Don't know how to get cpu temperature.
I would imagine you're using your phone inside a house, with temp. probably around 20-25C. Now I looked at battery statistics on my phone and it seems my phone's battery never went above 40C in the past 2 weeks. I don't think 37C you got is something to worry about yet, but if your battery is 30 even at idle inside of 20-25C room??, you may want to look into why your phone is running, when you're not using it. Another possibility is that your temp. sensor is miscalibrated and it shows little high. In other words, when your phone is not being used, it should be in deep sleep mode and battery should be withing couple degrees your room/ outside temperature, depending where you are.

Can you please advice any app to see what's running when phone is in deep sleep? I have a custom Rom, and I noticed increase of temperature after last update (or maybe I installed some root software that causes it)
Mine does not seem to heat up much at all, it is about room temp while playing games and what not. S8+ ATT
Do you have root? if yes, wakelock detector should show you what is keeping your phone waking up.
If not, 3C tools has whole suite of applications including nice battery manager, it keeps log of your battery charge/ temp etc every 10min, there is apps manager etc.
Have 2 days s8, same settings usage than my s7edge, and it's getting hot, I don't know the previous update, because i update and reset before use the phone.
But with Bluetooth on link to the car, and reading already went to 41 degrees its to much compared to s7.
Maybe I need to change it.
So, I noticed that When gaming (especialy with game offering 60 Fps mode) the phone will freeze and then goes into reboot even when played on cold room
from CPU temp apps, it seems when the temperature hit 40 centigrade. the phone shut down
Anyone else have this kind of problem ?
is bellow 40 centigrade is the safe limit for this phone ?
for all its awesome spec it kind restrictive for use gaming
This is by far the coolest device I've ever owned, no heat no matter what I throw at it. What does your setup look like? (ROM, kernel, etc.)
Its basicly stock one. since I just got it 2-3 days ago
Im testing it to run some CPU intensive games (60fps)
when the temperature reach 40 centigrade. it shut down
on normal usage it is quite cold.
but it seems the thermal threshold were quite low, my old HTC might also throttled down at 40 centrigade
but it dont shut down until 50 or 51 centrigade.
1+ 5 dont thorrtled but instead goes straight into shutdown
my country ambient temperature were quite high due to located near equator (30 centigrade avg, with 35 centrigade being common on daylight)
so without air conditioned room, I found it can become overheated - rather quickly
only had overheat problems using camera related chat apps (kik) and in 110 Fahrenheit degrees in CA USA

Might be a bit of an extreme solution but try doing a factory reset and see if that helps. If not, contact OnePlus support and see if you can get an RMA started. I say that because my device stays cool even on the hottest days of where I am.

I agree with the RMA solution, something isn't right because I can do anything on this phone and it never gets hot. Even when it's 99 degrees Fahrenheit with 70% humidity here in Ohio.
I've done some seriously intensive gaming and crap on this phone, and I cannot get it to overheat.
The snapdragon 835 is the coolest phone processor, you don't have any overheating issue, it must be something else. When you say 49° are you talking about the cpu, battery, skin temp?

both battery and CPU were at similiar temperature (+- 2 degree)

Cpu at 40° while gaming is really low, some phones hit 85°, of course they will throttle after that.

yeah. Thats why when the phone shut down after reach 40 centigrade.
its confusing since the thermal threshold should not be that low
same problem here
freez then reboot in heavy games
temperature around 40-50
factory reset doesnt help
