[Q] Safest Max Battery Temparature?

Many users may find their phone gets quite hot, thankfully Aluminium is a heat conductor and dissipates the heat in the cold air but Sensation owners may find the phone can feel quite hot at the back and possible the screen feeling hot too.!
So far while gaming for about 10-15 minutes, I have had my temperature reach 46 degrees celsius.(~115 Fahrenheit)
I think the failsafe temperature maybe around 52 degrees Celsius(~125 Fahrenheight)
Anyone know what the failsafe temperature is or what should be the highest safe temperature?
how hot has your device gone?

Highest temps i got was around 41 degrees Celsius, this was while playing gameloft games (heavy 3d graphics).

could be charging and gaming same ime causing 45.9 degrees celsius

1 hour gaming (galaxy on fire ) and at the same time charging and i guess wifi was also enabled and the highest which I saw was about 45.8

Spoke to HTC
normal operating temperature is 30°c to 40 °c
Anything upto 50°c is safe and erl not harm the device

I managed 46.4 last week.
Anyone think they can beat that? If not, what do I win?

was charging the battery and concurrently doing a large file copy (about 5Gb) to the SD card - on my widget monitor - temp went up to about 50C, phone body was getting noticably hot and there was some distortion on the screen (multicolour "snow" on some of the widgets).
finished the xfer - shutdown phone for about 15 mins to let it cool down - haven't had the same problem since (altho I haven't done such a large file xfer again either)

Well, i'd like to keep it below 37 at all times. After having mobo in Desire replaced which had heat issues (just look up desire overheating and rebooting), i'm very cautious regarding temperatures.

Had mine up to 48 degrees while it was in my pocket, best thing is I didn't feel a thing till I took it out and damn... way too hot =S

Mine was at 55oc whilst charging overnight once. Still fine though, although I suspect there is something wrong with my battery. 4/5hrs mild use took me down to 55%!

You should check battery information in spare parts. Check if it says battery health overheated instead of good.

That was a few days ago, battery health now says good but at the time it said overheated :S.

[Q] cell phone cooler

hi..
when playing ingress my battery can reach up to 50 -52 degrees celius, while my CPU can go to 60-70, sometimes the phone shuts itself down.
are there any packages i can use with heat sink or something similar to vent off the heat ?

Is your phone in a case? Many of them would act as insulators, trapping heat inside. Running without a case will probably help it stay cool. Also, I think the unit will run cooler with the keyboard open.

I've got nothing to productive to contribute to this conversation other than I've noticed this too.
The phone will be unbearably hot to hold. I've tried to see if any application were running in the background, eating up resources, but there's nothing consistent that I can report. Some days my phone will go all day long without any problems. Other days, the phone just drains the battery really fast, gets really hot, and displays an over-heating message. The only thing I've been able to do is shut the phone down and remove the battery and wait a few minutes until it's cool to the touch, then put it back in.

Same and this is a relatively new issue.

I used to play Ingress about 6 months ago on my old Cliq2 and I can confirm it uses a lot of resources. My phone used to crash all the time due to, I guess, not enough memory. And it was rooted and fully debloated.
You won't be able to easily extract the heat from inside your phone. One thing you could try is to play without the back cover. Just tape the battery so that it doesn't fall. You'll have to be careful to not damage anything that will be exposed on the back though.
Another thing you can also do is slow down your CPU using some app. If using CM 10.2 it's very easy to do. Go to the performance settings and choose a lower maximum frequency.
Finally, the last idea I can offer is to tether your phone and play using a tablet. The best setup I've seen is some guy having a tethering cell phone in a backpack, with a large extra battery connected to both the cell phone and the tablet he was actually playing from. He could play all day like that.

Well we're officially supported on CM so not bad I suppose ;p

CM-10.2 will run cooler than stock due to use of AVS. This dynamically adjusts the CPU voltage levels to reduce power consumption and heat, even when the CPU is running full out.
Also note that not all CPUs are created equal. Some require significantly more power to run stable than others. If your bootloader is sending sec_pvs=fafa as a kernel commandline argument, then it means that somebody up at samsung or qualcomm has determined that your CPU needs full on maximum power, which basically means that it will be un-nice on battery and heat. PERIOD.
To reduce heat levels, run it connected to a >= 1 Amp wall charger (to keep it from sucking off the battery -- note: NOT a USB port), keyboard open (more surface area = more heat dissipation), and BACK COVER REMOVED (reduce insulation).

I've noticed that the phone can get warm, but the only time I've had overheating issues was either a) during a long rsync-over-SSH run on Wi-Fi, or b) phone left in car on a hot day with GPS and navigation (either Google or Sygic) running. The latter was fixable by running the air conditioning.
In my experience, it has just been hot enough to shut down charging, not the entire phone.
I've just ditched the case, mostly because the plastic tabs don't work very well. I'll have to see what this does to thermal behavior.

S6 heating!!!! help

Hello guys.
So i bought the s6 non edge 32 gig model 3 days back. The phone is awesome no doubt but i had heating issues from the very first day. First i thought it might be the battery drain. did factory reset and i was getting 4hrs+ SOT with 5.0.1.
Now i am on 5.1.1 and the battery seems to have improved giving 5hrs SOT. But the phone heating issue remains the same. The phone gets warm about 92F above after 5 minutes to 10minutes normal usage.
Using the phone for 30 min the temperature is near 100F . is it normal? Cpu spy shows normal activity.The phone only heats while using it is cool with screen off. The heat is felt on the left side of camera and spreads around after more usage. Due you think its because of the climate. i live in a place where summers are always above 93F . But even in AC phone gets pretty warm.
Do you think my battery timings and phone heating is normal. Please comment i am quite worried about it i spent a lot of money on it.

i think if you're worried about it you can bring it to Samsung Service Center to get it fixed.

i donot have samsung centre in my area. infact i have to ship it to dubai to get it fixed. can you tell me does your device gets warm after using it?

wow that's pretty bad, sometimes, when using too long for battery consuming applications like gaming or such, but when i put it into my pocket when it's warm, it gets hotter.

you can try downloading CPU Spy Reloaded to check your CPU state usage, get better battery stats as well to check what is consuming your battery the most

okay so i downloaded both apps... the cpu spy shows no sign of abnomal cpu usage... it is in deep sleep for most of the time. better battery stats show no app draining battery... i only use fb/messenger and gmail app. today i got 5 hrs SOT with 22hrs usage time. i think the battery us fine but why the phone warms up so much. My question is how oftenly do you feel that yous phone is getting warm?

Maybe brightness is too high causing the phone to heat. Cases also make phones overheat.

he could be using auto brightness, which also causes the phone to spike the brightness and heats up faster

Hey, I had a similar problem with my Galaxy S6 32gb and I would only get roughly 10 hours battery life out of it with 2 hours screen on time and as soon as I turned the screen on, it would be so hot on the right side, you couldn't actually hold it. I just ended up selling it and didn't think to contact Samsung or anything because it did it every time I turned the screen on so I just thought it might've been normal. I always had everything turned off with just wifi and auto screen brightness on and just 1 Google account synced too. :silly:

that's a sad story you shouldn't contacted Samsung to get it sorted out

Figured out it was a hardware issue... there are two ways to check if you s6 heating issue is software or hardware related. install gsam battery monitor and see if kernel or android OS (apart from any third party app draining) is draining most battery than its a software issue.
otherwise its a hardware one. i got mine replaced and the new one works fine.

this phone gets hot!

damn, gets hotter than my note 4! what's the max temp you've reached? I'm at 100 degrees f now just browsing around on my lunch hour. kinda annoying, honestly.. part of the reason I hated my Moto X Pure Edition was bc that thing would regularly hit 113 degrees and be annoying to hold. hopefully this snapdragon isn't as bad as the 808 was!

I would say that this is not normal. Mine does not get hot... only warm during gaming. Also the tests confirm that the phone does not get really hot. Maybe it is still in the set up phase?

could be! battery sucks today too haha. I'm also not using wifi ever.

Are you out in the sun when this happens? I have yet to see this phone get more than warm.

I have hotspot on and I am using a wireless QC2.0
The phone gets super hot until it reach 90%, then it becomes lukewarm.
At 100% charged, its very little warm.
Is this normal?

Yes, wireless charging heats up the phone a lot. The phone automatically slows the charging speed to prevent the phone from overheating.

nah. i was inside at work at lunch from like 12-1 browsing stuff. hangouts tends to get phones hot for some reason, and i was browsing other apps for like an hour straight. but yea, she didn't hit 100 luckily, but yeah, pretty damn warm.

Mine got really hot, M9 hot during the intial install of apps etc but only gets warm afterwards

This phone is by far the hottest I've had so far

Its not good to use the phone while charnging. Especially fast charging. Maybe very little use at most.
My phone has only got slightly warm, and that was while playing a racing game. Everything ells is room temps

Heat test.

I don't feel any particular heat from mine, even while running intensive games or benchmarks, then again, I am using the Exynos variant.

A littlebit warm after 1 hour of Real Racing 3. Not hot at all. Htc one m7 was hot phone. .

Mine is charging right now with the fast charger, while streaming radio over bluetooth. Its warm, but not what I would call hot. My LG G3 got significantly hotter. Even playing with my Gear VR the other night it only got pretty warm, but I've no idea the actual temp, I just know it isn't as hot as my G3 would get sometimes just playing games.

Mine doesn't get really hot like my S5 or M9. The hottest ive experienced is like warm to the touch. Not HOT. Mind you, I'm wireless fast charging constantly.

Yeah at first I thought my S7 was cooler than my S6 Edge but even with just Web broswing for an hour or so the S7 is averaging like 90 degrees F. Current temp is 94. It's warm not "hot" but still annoying.
I think the Speck candyshell plastic case made it worse... trying to use bare now but still a bit warm.
I may have to go back to a flip case or something.
I hope I can get used to the warmth (tho I'd rather not have to -- def. annoying). Other than the warmth this phone completely rocks. I think I'll probably have to adjust because it's so damn amazing. I doubt any other phone can compare.
Name an Android phone as powerful as this one but which stays cooler... is there one?

Mine gets quite warm as well would sit around 32 degrees Celsius from browsing the Internet. I'm just worried if it's a defected device or not cause I have the exynos and some people don't even go over 25 degrees.

Yeah, I'm seeing this as well. Qualcomm variant. Just web-browsing for half an hour causes a pretty good bit of heat at the top of the phone, though I haven't checked the actual temperature.
I don't mind the heat itself, but the phone clearly start throttling and even just scrolling around in Chrome becomes laggy. Annoying.

lately mine has been ok surprisingly. not once did it even hit 90 today on lte all day. battery has also gotten a bit better. it's been a full week today since I got the phone, so who knows, maybe it really does take a week to settle which is kinda crazy lol

Brand new S6 feels warm in light use

Hey guys. I'm from Brazil and I have just bought a Samsung Galaxy S6 (SM-G920I). My previous smartphone broke almost a month ago, so I may have gotten unused to a high end smartphone. It turns out that it is feeling warm during light use like browsing or Facebook. I can't tell if it started after the firmware update because it was one of the first things that I did when I turned it on for the first time. The temperatures that I am recording hovers around 38 °C to 44 °C. When I switch from Facebook to CPUz it is recording around 52 °C but starts dropping right away reaching around 43 °C. It is not hot, but it bugs me since it doesn't seem right to an octacore smartphone feel warm when browsing.
*I've just recorded a 1 minute video in ultra HD and when I switched to CPUz the temperature was at 70 °C, but also started to drop, stabilizing a little at 51 °C.
I've already cleared the cache and did a factory reset.
Do you guys think that I received a faulty smartphone?

I have the same problem on SM G920F which i bought several days before sometimes it goes around 36c battery and 63-64 cpu with no good reason for , like light usage(like messenger,snapchat) it works fine but its heating up and feels quite annoying for hand did anyone experienced same thing, and will buying a case for phone at least make feel better for hand?

Well, my phone was at 48 °C - 54 °C when it was in my front pocket and running only 4 apps on background (WhatsApp, CPUz, browsing, and outlook). It is not even hot in Brazil right now. Honestly it doesn't seem right!

It is normal. The CPU is just too powerful for heat to not build up.
Rest assured I played Walking War Robots on my phone for an hour and a half until my phone was hot enough for me to not be able to hold it comfortably. Nothing happened, I let it cool down for 10 minutes before Fast Charging it.
If it does not show any overheating message then it is not a problem.

Well considering it was built to be premium model its kinda dissapointing , like being 5 minutes on snapchat or 10 minutes of light usage makes him warm and a LOT of worse phones cant heat unless you like play games 10 minutes or really load them.If i put a case its heating like 10-15 % more.
I m suspicious because i havent seen a lot of people complaing about heating verry few people complainted about this.But phone is really great only problem (for me) is heating.

Thank you, I appreciate it.
It makes sense that such a powerful CPU would generate some heat, but at the same time simple processes like these
shouldn't cause any level of warmness. I also checked the battery temperature which could be damaging for the phone
and it didn't raise the temperature as much the CPU. My phone had just 2 days of use, so I sent it back and I'm waiting for
a replacement. I will keep you posted.
