Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the Nextbit Robin stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.

Can get hot if using Quick Charge and playing a game at the same time, with the hottest point being the back near the cloud logo. It's noticeably hot, but doesn't seem any more so than other phones.
Getting quite hot for me during general use. On occasion barely doing that much as well. I think the CPU could do with some custom kernel love to try some undervolting and governor tweaking to help.
I think it might have to do with the fingerprint sensor. Mine gets hot with screen time.
My Robin used to get hot but not much anymore with the newer updates.
Mine gets really hot when playing Pokémon go, but I think it's because of being a bad optimized app.
My Robin gets hot no matter what ROM I am using. I have tried stock, AOSPA, Lineage and Omni. I emailed Nextbit customer support about this issue when I first got my Robin (when they still did email support). I went through the battery tests they suggested (FCQ (*#*#6721#*#* on the stock ROM) and Ampere) and provided them with screenshots. They stated that the temps I was showing in the screenshots of the battery tests I performed were 'normal' for the device.
I have found that the Robin is really sensitive to the temperature of the environment that it is in. On hot days, under mild use, the device gets very hot (like battery temps around 110-116 F).
At this point, it is what it is. I think that the excessive heat is a combination of a processor that is known to run a bit hot, combined with the materials that the phone is made of.
I had it to film a concert (sound is ruined on any videos, pictures ok..ish) But the thing, it was incredible hot, i had to stop using it during the concert and it felt like it burned a hole in my pocket for a bit after i turned it off, and it also gets reallly hot around the fingerprint sensor, and the display itself was like a pocket warmer.
Might been cause i used a Thick and robost phone case, cause i am afraid i break it anytime i put in my pocket....
Send it back to amazon and got my money back now. (Bought it just when it dropped to 100$, now its gone from amazon.de.. lol)
I use mine as a coffee maker

Agree it has been the coolest phone I have owned. The other phones I have owned have both got very hot which has made the phones very slow (CPU throttling?). The Axon 7 has stayed quite cool to the touch even when using things like GPS and camera.
Nexus 6p (toaster)
Oneplus One (hot)
HTC M7 (hot)
iPhone 5s (mild)
Axon 7 (cool)
Warm/Hot
Got my Axon 7 today been using it for a few hours was warm throughout my usage, gave it a charge and was really warm/hot. Battery life wasn't all that great either, people are getting 5-6 SOT with a full charge, it came with 85% out of the box and used it for around 2~2.5 hours and it was down to 20% with brightness below 50% wasn't impressed. I'm hoping it'll get better with more use as this phone is pretty great
If you play all day of course you wont get 6 hrs of SoT.

Yup and Yup....
Comparing the Axon 7 to previous devices, A7 win by a long shot.
I play PSP Games (this is hard on CPU+GPU) and doesn't transform into a toaster.
I've gotten 6.5 hours of screen on time, but this is with conservative use: web browsing/video watching with extremely low brightness settings.
When playing Star Wars KOTOR, I've only gotten ~3.5 hours of play time. Brightness heavily affects the drain speed.
it gets barely warm enough to notice it working at all.
Got hot in pocket while doing nothing, GSam showed 38-40 celsius. Started today, exactly after 1 week when I got it. While using it it gets warm a little, but nothing serious compared to my old phones.
Axon 7 Battery Temperature
Hi guys my Axon 7 is running the latest update (7.1.1) and my battery's temperature is 29°c when idling and the room's temperature is also 29°c, but when I start using social media apps like Instagram and Snapchat ,it gets around 37° and if I use Chrome for web surfing it gets around 40°c, so is this normal for Axon 7? And also if I use so heavy multitasking like downloading over mobile data, watch online videos , two sims both activated , and ten other apps open at the same time but no games , the temperature sometimes goes up to 45°c. What is your Axon 7's battery temperature in different situations?please also mention the room temperature that you're in. ( to see the temperature go to settings/ power manager/ battery cooling)
With Gsam Battery, it says 43 celcius when charging or reddit/games...
It was under 35c a few weeks ago
It is normal for many phones.
And the temp alert settings of the axon7 are very useful as I sit in sunlight very often and most times forget about phone temperature
My Axon 7 heats up fast when I used aze
The battery monitor reports overheat warning after 20 minutes of using the GPS app called Waze. The temp would reach 46°C easily. I don't get this issue when I use the Google Map.
I have seen temperatures in excess of 50C when in direct sunlight in my hot car while using GPS (no A/C in my car).
Playing Hearthstone in my warm room can exceed 40C, which is where I have the warning set to.
I hope I'm not slowly killing the device or battery...
My A2017G gets a little hot (but definitely usable) when charging. Unplug it and it'll cool down pretty quickly.
But then that might be because I keep the phone on all the time (got an always-on screen app running just for screen-off OK Google)
This phone doesn't get hot. You guys don't know what's hot until you have used a Xperia M4 Aqua
My Xperia M4 Aqua could reach temps of steady 82C while gaming and 74C while watching Youtube
I've been getting issues using mine as a GPS with here maps. Battery heat warnings and yes, it felt hot, not to mention the app is causing navigation problems a lot.
Installed TomTom, see if it works better. It has some better UI and settings already.
If it doesn't run cooler I might buy a dedicated GPS but really don't want another device in the car.....

That's really weird, my phone never gets hot while using GPS and driving. Are you sure you're not putting the phone in direct sunlight?
Yeah, of course it had sun on it. You need it able to access GPS signal reliably for good navigation.
It was in a screen mount. I was using it heaps today on TomTom app with much more success and less heat. Seems there's something not right with Here Maps.

You don't need the sunlight directed onto the device.
I got a mount on my with a shieldscreen to protect it from sunlight so it won't get cooked. I am guessing you're enjoying a cooked phone while driving
when using wifi/4g in my house, i watched video, browsed fb and even shared internet and all. below i'll give my observations:
in wifi:
watching video, fb and browsing, whatsappin: the phone get very very slightly warm like not warm just the bit different from the phones usual temp like it hovers around 33-34.
when gaming in wifi it goes arounf 36-39 (NOVA 3) battery never crossed 31..
4g in my house, battery arounf 32-33, temperature around 37-39 for all.
but when i step out of my house, like when i'm operating my mobile in train/bus and the ambient temperature varies from say 28-32, my phone gets considerably hot and today, i was travelling in Bus and the ambient temp was around 35 and i was just browsing , watching videos and fb, my phone became hot like it even would have touched 43-46! i felt it hot to touch, is this norma(it's making me extremely paranoid)l!!??? if this is the case what happens if it's summer here, the phone would become blazingly hot, coz in summer ambient temp would be around 36-44 and all!!
Is this normala or am i unlucky for the second time ? I'm getting paranoid!
Just hit them back up

Are you serious.... When the ambient temp is 35 degree what else would you expect... Every phone on the planet will get that temperature. Can't believe you had a phone returned for this. You know the front of the device is black and absorbs light... When the sun hits your phone it's gonna heat up also. This phone is the best Android phone when it comes to thermal throttling.

With heavy multitasking, I hit 60+. Not regularly, but it has happened. The temperatures you're hitting are normal for me. I've had zero issues with the device. I have an OtterBox case, so I don't feel the heat as much. Honestly, I barely even notice heat at those temperatures. Considering the fact that the body of the device is aluminum, it's going to easily get hot to the touch.
Also, my One would almost always run between 45-70, and I've had that since launch. Used it heavily daily for years, and I still use it regularly as an app development device. No issues.
These devices have extremely powerful processors. They get hot. There's not an easy, efficient, way to cool a processor in a device like this yet, but they're designed for heavy use, so I wouldn't worry about it.

Hi first of all thanks for the reply.. I'll tell you what really made me paranoid.. Every evening I travel in bus and train and the ambient temperature would be from27-28_29.. I use 4g jio.. I just browsw/fb/insta.. In minutes my phone near the earpiece on the screen gets warmed up and it'd go around 40-41. Then I lock it it cools down fast but when I unlock it in seconds again starts warming up... My friend using same 4g in moto g4plus but his screen is cooler than mine... Please my one last doubt...
This is nothing lol. I live in Scotland so just now ambient temperature range from 5-13 °c and in my house 21-23°c and my Z3+ hits 60-70°c easily on heavy use. Benchmarked it one day and hit 90°c. The joys of the 810 chipset. Anyway away to upgrade to the OP3T so i should see and feel a massive difference.

Install a custom ROM and kernel and limit your background tasks. You may just have a bunch of things running using your CPU.
Thank you all!
Hey all thank you guys very much for replying to my thread! i'm really feeling okay instead of getting paranoid with my phone.. although i'd be very happy if you guys just clear me this last doubt!
today I was playing NOVA 3 connected to wifi in an ambient temperature of 25C, 5-10mins into gaming, CPU reaCHED A MAX OF 41c and at around 20 it maintaining at 43 but jumping sometimes 45.. this is gaming, but i get the same temperature just browsing in knda same ambient temp while I'm travelling. and also browsing in wifi/4g(fb,insta,chrome) in my house in ambient 25-27 gets the phone phone to 35-37... and the rest of the pat of the mobile is cool, even the back side is normal, only the small portion between the earpiece..
why is this happening? is this normal(it'd be great if you guys clear this)? if yup y so? and why phones like oneplus x and moto g4 etc have relatively less temp than OP3..
I know it'd be irritating to answer kinda same question again, but this would my help paranoiac freaking out for my mobile will go down..
thanks in advance for your replies

Because the Oneplus 3 is a lot faster, the Temps you are giving are n even close to hot... This has been one of the cooler phones so far.
Like others said, those temps are completely normal. Hell, I'd even expect them to be higher with your fairly high ambient temps.
About comparison with other phones - it all depends on internals and design. OP3 is made of aluminum so it'll dissipate more heat into the case - you'll feel it better. Other mentioned phones are plastic, so they'll contain more heat inside (you'll not feel so much heat, but the cpu may even run hotter).
And OP3 has cpu located just below the camera, so it's normal that it reaches top temps in that upper center part of the device.
P.S.: You talked about loads and ambient temps, but didn't mention screen brightness - that also plays a massive role in running temperatures.

for me mostly brightness bar will be in the middle... i never use it with high brightness..
Just get a case and maybe a screen protector so that you can't feel it getting hot.

hey ya !! sorry to disturb you again and again.. just a urios doubt.. what'd be the temperature of the phone or how hot can it gets, when u use 4g and fb app in ambient temperature of 29C and 33C..
mine got arounf 38-41 for the 1st cse and around 43 for the second case..
I know i'm being paranoid, ,but please, clearing tis would help stop worrying a bit
All the temps you posted are normal
About Moto g, it has much weaker SoC. A Ferrari's engine gets much more hotter than a toy car. Doesn't mean there is anything wrong with Ferrari
4G /3G active usage can get hotter than gaming. That's also normal

Nothing much to worry here. Even I use Jio all the time. My OP3 get a lot hotter than any other device I use before. Reasons I knew are these.
1. OP3 rock with a high end processor. Say SD 820. Other phones you mentioned are consisting of relatively lower end processor. So internally they might heat up more that OP3 while doing high processor intensive tasks, but the plastic casing keep the heat inside, as OP3 is made up of Aluminum that being a metal heats up so quickly and and u feel more hotter in hands than the other ones and also it cools faster.
2. AFAIK the processor is situated just below the Camera bump. Hence it heats up very quickly at that area. Irrespective of outside temperature.
3.While using 4G network it's obvious that the phonehave to communicate with the network at a very high rate than 2G or WiFi. So it's clear that it will heat up. Also using high processor intensive application like Facebook gives the processor high stress and it heats up in no time.
Remedies
1. Use a case. That somewhat helps in insulating the heat.
2.If possible use WiFi rather than 4G network. That will considerably helps your battery life.
Conclusion.
Don't worry about the warmth of the phone.Its normal. Just enjoy using the phone.
Never Settle.
Cheers.
Clearly never experienced a SD810 device. I'm sure Snapdragon took there name too seriously with that chipset. I could hit HIGH 80°c in seconds playing basic games, using the camera and under heavy usage. Had to tailer my use around my Z3+ but now I have the 3T I can do what I want and it never goes past 50°c so far.

Got the phone today, and it feels very cold to the touch. Most of the heat It gained was from my own hands... though it is winter. I then put a silicon transparent case, and after setting everything up I did some google cardboard vr for around 30 minutes and felt a light warmth through the case... barely noticeable.
Mine is getting pretty warm after rooting, making a nandroid backup, and flashing xposed. Not quite uncomfortable, but very noticeable.
My phone has only heated up a couple of times, and that was when I really used it, games and such.. Otherwise it's really "dead" to the touch.
If you want to heat it up, use some benchmarks, or if you want to be more productive, use mapillary outside and photomap your area around.
Yes.. it's getting heated very often even I use for 5mins.. I got phone today only(23-12-2016). Please suggest a solution.

For me its exact the same thing...
Of course its gonna heat up if your cpu and gpu are working at max speed all the time.. its normal
First day when I flashed custom rom, installed all apps, rooted, twrp and all that it was hot to the touch because the reason above but now when I use it in a normal way its actually cold to the touch most of the times and I love that
I rooted mine and installed a rom really got hot then I changed to a different rom and it is very cool now.
OnePlus 3T is a really cool device. I suggest users to buy it. It has very cool features like Fingerprint access, Camera etc.
But if anyone gets Official TWRP for Android 7.0 for OnePlus 3T, Please tell me*
Never felt any kind of heat through the case (Orzly 2-part case).
Never been an issue.
i have noticed it's evenly warm when it shouldn't be. try enabling "Auto close high power usage apps" battery options.
the description makes me laugh. engrish.
"When it runs, the system auto clean up background power-hungry apps , prevent phone from getting hot."
It doesn't warm up much, if at all, for me, but I am using a rom that underclocks the CPU which could be the primary reason for this.
On 3.5.4 I would have occasional heating after a phone call. Battery stats would show that the phone was using the CPU for extended periods after the call had ended. Usually a deep clean of the ram would solve it. Sometimes it didn't solve and then a reboot would solve the problem. Phone was completely stock.
It was comparatively very cool throughout with the CPU temps being in the mid 20s or low 30s even during charging at 3.4A with the dash charger!

Heating issue
Got my phone few days ago its heating when i am playing clash of clans but otherwise no issues in normal mode.
Nvm
The phone stays cool to the touch even under heavy gaming. (Max 35C on cpu)
Heating hasn't been an issue so far. Had an app causing constant 70% CPU usage and the device was just slightly warm
my phone getting hot sometimes idk why
Any manufacter could make a super cool phone by just setting an agressive thermal profile. Oneplus 3/3T doesnt throttle at all, not with gaming. The phone gets warm, but you have to consider that it's using his full potencial. I prefer a hot phone (not the case) than a cool phone with half of the power the soc offers.

Mine has not yet heated at all! I have used Zarchiver to zip and unzip, several large games (modern combat 5, order and chaos 2 etc). Even in direct sunlight, the phone only became luke warm!
same story...this phone remains cold. in every condition.
for me it it the coolest phone i have ever had
I live in a tropical country, so the ambient temp is high most of the time. Despite that, my phone only gets really warm, but not too hot. Very impressed with the thermal management on this phone.
I just got back from Mexico. Jumped in the pool and didn't realize I left my phone sitting in the sun. According to GSam Battery Monitor, the temperature of my battery was at 50 degree Celsius and it was only luke warm to the touch. Very impressed. I was scared for my battery tho lol
i play Clash of Clans on my XZP and see the temps getting as high as 106 degrees. It's pretty warm in the back. Not sure how anyone is really able to say theirs is "cool" all the time.
PC is not cool when playing games. Why would be XPERIA XZ Premium cool when playing games?

Because its cpu's tdp is under 5 watts with the integrated gpu while a pc's cpu could easily go over 100 and have additional gpu and other heat inducing components around?
Don't get me wrong, many phones get hot during intensive gaming and that's not a huge minus considering they don't have cooling. Sony's done good job with it and it's on par with other flagships with sd 835 considering it's a pretty efficient chipset. It's just that the comparison you made was out of place.
Mine does get warm sometimes, but that's it. Just warm.
My old G3 used to get really hot near the Power/Volume buttons when gaming or running VR apps.
It's the kind of hot where you notice it, but it doesn't really bother you. Unlike my G3 where I had to move my fingers away from that area.
More importantly, it hasn't stopped an app or lowered the brightness due to heat yet.
Omg 50.7 dc
My phone can get hot doing VR stuff, but otherwise it seems near impossible to get it hot unless it's a very hot day and I'm out in the sun.
Then it's possible to get the camera app to warn about heat, although this has never actually progressed on to the point where the camera shuts down. Not like my Z3 where 10 minutes of photo taking and that was your lot.
The phone is amazing, I manage to record 4k videos more then 30 min and phone didnt need to turn off cus of heat, like on Z5P.

Mine only gets warm when viewing 4K Youtube HDR video
Never had this phone overheat. Even when video calling over 4G.
pretty cool always, can get warm but only warm
in love with it, snapdragon 835 does the trick to prevent overheating.
although when viewing 4k content or in 4k mod it does get hot, but hey which device wouldnt showing 4k? im impressed
i live in Jakarta,Indonesia and my XZP only gets hot when the signal is weak.other than that the device is around 30 celcius to 37 celcius.
Well to add to this conversation , Got this phone and regarding heating it heats for sure in some situations, but not as much as Z3 dual in same situations (my previous phone) and I am not worry about heating as Z3 dual heats a lot when playing pokemon go on sunny days during summer and never had heat warring except playing same game in background while recorded HD video of car crash in front of me, that is only when I got heat warning on Z3. On XZ premium same situation I could feel some higher temperature in hand, but not even close to Z3 , and another worst situation is game pokemon go and mass evolving in game (who knows what is it) it brings Z3 to very high temp, while XZ premium gets up to with temp enough to be able to feel it. Zip large files with password 128 bit encryption or unzipping does not produce any heat on Xperia XZ premium, overall it is very cool phone.
My phone does heat when playing games like Shadowgun Legend and Modern Combat 5 but I didn't notice any throttling.
Mine was hot while i was filming 4k in a 34 degrees outside in the sun.
i simply solved it by dipping the phone in the pool voor 10seconds and it was fine again. made nice videos
