Charging Temperature - One (M8) Q&A, Help & Troubleshooting

What temp does everyone's phone at? I recently got a new cable and i was charging at around 37C-38C the phone felt pretty warm at that point too, and the estimated charge time was practically cut in half from when I used my old charger. I wanna say my old charging temp was maybe 34C.
I know hotter is worse, and the slower the charge is better, but how much worse would it be at that little temp difference?

Well, this temperature shouldn't be a problem, as the cpu temp is getting mostly around 55C and I must say that it's a great device in terms of heating.
The whole metal body is getting warm, but only one spot like in the other phones, so you should care about the temperature.
Just check if m8 supports fast charge, but I think it does.
Please keep in mind that processor in lg g2 is reaching even to 70C, so below 40 it isn't so much.

How hot is to hot?

The other day I had my phone on my car charger I picked it up and the back was very hot.The phone was only on charge for like 20 mins and it was only like 40% battery. I looked at my temperature and it said 44celsius and I then installed battery indicator to see what it is in farenheit and it said like 110. (can't remember exactly) I've never felt it get this hot before and I was wondering what temperature is to hot for the phone? Thank you for your help. Also what could cause this? A short maybe in the phone?
Were you running a cpu intensive app at that time? When I have my phone charging and I'm streaming videos in 4g, it gets pretty hot sometimes.
Personally I can handle quite a bit of hot but Mila Kalunis on Natalie Portman in Black Swan was just too hot.
Well come to think of it I ran smart bench 2010 and speed pi on it and the set it down and when I picked it back up it was very hot. I guess it's normal for running intensive CPU things. I just never felt it that hot before
Yeah it gets hot when your charging it and in a bad signal area.
If you don't want to worry about charging your phone all the time, You could buy those 2 Epic batteries off ebay, There was a huge thread in the other section. Well worth it because it comes with a additional wall charger.
These phones are pretty heat resistant. This past september just after I gotmy epic I left it charging overnight on the window sill next to my bed. I live in phoenix, when I woke up I checked my phone and immediately dropped it because the glass on the front was so hot. The setcpu widget (was on di08 overclocked to 1.2) read 168 degrees F. Phone was still 100% functional at that temp and I've never suspected that it was damaged in any way.

Does your screen get hot after extended use?

By extended I mean 5 min. I can really feel the warmth when I put it in my pocket.
I used my phone today for at least 3 hours straight and didn't get hot at all. Most of the time surfing the net.

This topic is already being discussed in a different thread, but since yours has remained open I'll put in my 2 cents...there has been numerous reports of the phone reaching extremely high temperatures, one as high as 140º and my phone has gotten up to 121º!!! I truly think its a manufacture flaw as all 3x that mine has overheated I wasn't overclocked nor was I doing anything that would have required a great deal of the systems resources. As I've stated on the other thread, I have a Droid Incredible 2 that I can run all day overclocked at 2.035Ghz and it will never lock up on me, let alone overheat!!!...Something that I realized today was that in MENU>SETTINGS>DISPLAY>BRIGHTNESS>It'll say "brightness has been reduce to avoid overheating" or something close to that affect and it'll be scaled down to about 3/4 of the brightness level when my phone starts to get hot, so does that mean overheating was already a known issues before they even shipped out the phone??? And if so, has it been built to withstand these temperature that others and myself have been reaching or did they ship them out anyways and are hoping for the best? I wonder...
I was playing some games (Nova, RUA) and the glass heated to the point it was hot to touch.
Oh, and it drained the battery so fast it died.... while charging.
I'm gonna swap it out tomorrow, see what happens.

Battery Charging Issue when Gaming!!

Hi Guys,
I have been playing Samurai Vs Zombies for some days now and I notice that when I play the game without the charger connected, the phone does get warm but not super hot.
When I connect my charger to charge while playing, for sometime there is no issue and then phones back becomes super hot and the battery indicator ,which is supposed to just give out red indicating charging, will start blinking red greed red green in that order repeatedly...
Does anyone else experience this and why is this?? What does the lights blinking mean???
Does it mean that the phone is overheated???
It means the battery has overheated and it will not charge until it cools down. This has been my top complaint, as it makes HOX unusable for car navigation, car recording or longer gaming (it will just discharge and then die)
WTF!!!!
Then how the hell will we use it for anything while charging.... You open maps and turn on GPS that will also create a lot of heat... Car navigation is screwed up big time...
I think if this is the case the new base 2.05 will serve much better as people have reported that the phone is relatively cooler when compared to the current build..

actually there is a precoution for this by HTC. when your battery is below %20 the CPU clock will be limited to 1000Mhz. the heat comparison between the 1Ghz and 1.5Ghz is 72C and 85C (these are the values i found out after stressing the device in a really hot enviroment for half an hour).. so when the CPU heat is lower basicly the overall heat is also lower and the device will charge itself again..
the good news is you will never run out of battery, the bad news is it will not charge above %20 and something and mosty you will be using your device at 1Ghz CPU speed.. but hopefully this can be solved with a software update (maybe limiting the current or the CPU clocks while charging)
i think the battery choice by HTC was a complete mistake (the one and only mistake the One X has).. it is not producing 5A but or anything, just an average battery but gets hot very very easily without any valid reason.. besides the unibody design is keeping the heat inside of the device.. i wish one day we will be able to replace it with an bigger capacity and more heating-proof one..

One plus 3 heating/warming even after replacement like the old one! is it normal?

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.

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.
