Bottom area gets warm/hot - everything else is great?!

This is odd but my Sensation is perfect from a hardware perspective right now (no guarantees on dust under screen in the future!) but for some reason the bottom area where the capacitive buttons are and the backside in the same area gets pretty warm/hot at times. Strangely no other area of the phone gets warm and the battery remains pretty cool. Also the phone doesn't exhibit any weird behavior or instability. I haven't had a single reboot or crash with this phone and I've been pushing it quite a bit.
So my conclusion is this heat is normal and how it's meant to be. Am I right?

I have the same occurrences with my phone. Great performance- I have YET to have it freeze/lag up bad or reboot.. and that is just amazing. Like I said in the other thread, the back of my phone will get warm, but never hot. I do think its normal, because it only happens after I have been using it constantly for 20+ minutes. (Still frightens me though)

I don't know about the bottom area but my screen gets pretty warm while charging and I am using it to play games or whatever but for normal use I never noticed anything else getting warm.

Just as a theory, the bottom there could be the location of the CPU.. I have yet to know or see a dissection of the device but i think maybe either CPU or memory is there.

CPU, cell radio, and charging/discharging circuitry is down there. The screen getting warm is just heat passing through from the before-mentioned stuff. Pretty typical from a beefy phone like ours. Good stuff!!

My phone gets noticeably warm too, especially when transferring a lot of data.

Mine gets warm when charging it at the same time I'm playing a game. My G2X is the same exact way. I really could give two ****s less how hot it gets. These processors were made to burn and if they burn up. Get a replacement.

Amen brother!

This happens to me too. It gets really hot when I'm charging it and doing something CPU-intensive.

all my touchscreen phones back to SPV's have got warm when in use for a while, so I wouldn't think this is an issue.

I think the reason why it gets warmer than other phones is due to the aluminum case. Aluminum is a great heat conductor, and the way I see it it's a good thing in this case. I'd rather have the heat spread to the outside of the phone, vs having all of those internal components burning up. With plastic shell phones, the heat builds up internally with nowhere to go. Hooray for heat.

If im charging and playing games for many hours, it gets a tad warm. A far cry from my other phones and unlike my iphone, the sensation does not lock up when. warm

I have same issue.I just buy sensation from tmobile store in full price and one day later I found when I am using phone for more than 10 mins the phone getting very very warm (hot) on the bottom of phone even more hot than hd 7
it is normal or not?? if not normal what can I do? can I call tmobile to exchange ?or htc ?

I think it's normal for our phone. and to be honest i'm sacred of using the phone for a long time either for gaming or web surfing it. well i just wonder would there be any water cooling solution for our phone like the one the pc. hahaha

Yes heat is normal. The CPU is in the bottom front of the phone. So that's where it gets hot. Heavy surfing and gaming will make for lots of heat.
For liquid cooling, place in ziplock and use under water

Is it the processor or radio?
Every HTC Android phone I have had (G1, MTS3G, G2, MTS4G) gets hot at the bottom of the phone when I am online with it, regardless if it's network or WiFi...they always get warm when I am online. Today every time I touched my phone it was warm at the bottom, as if I was online. So I force closed pretty much everything, especially things that may transfer data...but it stayed warm and my battery started was at 75% after 3 hours of pretty much no use. No calls, no internet, no texts, no games...just me shutting down programs. So I turned off my network. After that, the phone cooled off and my battery lasted longer than usual. But even then it's almost dead already.
Either the processor is simply too much for this battery, or there are things running in the background that are constantly streaming data. Either way root needs to come quick, or this thing is going in the box and the G2 is coming back out.

weird that only happens while i'm charging and doing something it at the same time.

Yeah, i've noticed it too. I also noted that it's right over where the battery itself is.
I chalk it up to how quickly the battery is being used, and these types of batteries aren't so great when you drain them fast. The inefficiencies start to show and they heat up.
I think getting a larger capacity battery, like the ones being talked about in this thread, might help lower the temperature. If the drain remains mostly constant at high output like that, spreading the load over a larger discharge range won't tax the battery itself as harshly.
Anyone with a higher capacity battery then stock notice it not getting as warm?

Device getting way to hot!!!

I've gone to using my spare xperia x10 mini pro now cause I've found while i'm out an about with my sidekick it will randomly get really hot an I don't mean like kinda hot i mean like feels like someone poured a cup of hot coffee onto thigh! The device hasn't been abused or dropped an its always had a tendency of getting warm at random it seams on all firmware versions. The only thing I can think of is possibly a issue with the phone connecting an unconnected often with the Bluetooth in my kia soul.
Now before you ask why I'm bringing this up now I had a none android samsung memoir befor this phone an it would get warm while GPS was enabled. Though in the sidekicks case it does it no matter what things are enabled or disabled x.x
So anyone else notice thier sidekick getting warm? with mine it seams like its something in the actual phone getting hot that in turn heats the battery up cause its around the DEL key on the keyboard.

are you running a 1.2 ghz kernel?
are their any wifi connections/bluetooth connections or any data transfer in the background that could cause your phone to clock itself @1ghz or above?
do you have any apps that run in the background (beyond the stock rom) while you are not using your phone?
your cpu could just be getting hot from background app usage while running @ the max cpu clock speed or overclock speed if you're on a overclock kernel.

The phone has never been overclocked an its done it totaly box stock with no wifi,gps,bluetooth activated an no data being used an has done this aswell with any connections enabled or doing transfers over blue tooth though since day one i do get a FC buzz when it first starts up but doens't say whats FC'd also notice when its getting hot that the battery amount is getting discharged by 10/20%

Hopefully it never got overcharged, or undercharged...
Have you ever turned it on after it turned off from 0% batt (or done this multiple times), I know that Lithium Ion batts have issues (I think it is 15% on the battery, but as 0% to the phone) if they go below 15% (0% in the meter) they will loose the ability to work correctly from then on out...
Calibration ever done at "NOT 100%", so it might think that 100% is 90% (or more) and try to keep charging?
Do you not charge it every night? (I have always charged all LiIon batts every night [mostly] and I have yet to run into issues with ANY batt.)

best to charge the battery with the cover off takes heat away from it

the odd part is that the battery never is warm while charging stays at normal operating temp for a happy battery. Now what I'm thinking is the battery is actually getting warm from something in the phone itself an transfering the heat towards the battery. An this phone has gotten warm like this even when it was less then a month old on box stock none rooted firmware of all types x.x

[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.

Question Pixel 6a overheats only in first few weeks, or indefinitely?

Many complain that the Pixel 6a gets hot or overheats. I have also seen videos were people claim it's only in the beginning while the phone "learns" your usage habits and how to optimize itself accordingly. But later on it doesn't need to run all of its processes like in the beginning once it figured you out, so to speak. (The exception being when you record a 1080 video at 60 frames, which even later on can get problematic.)
Can Pixel 6a users chime in here and recount their experiences? Does the overheating last past the first few weeks after purchasing it?
Bonus question: are the signal issues some complain of widespread, or not?
-----
I really want to get this phone, but I hesitate due to these two issues.

I didn't have overheating issues since I bought the phone 3 months ago.

Yup

I have my 6a 2 weeks and I don't have any issues with overheating or bad signal.

Thanks.
Anyone else?

Overheating in the sense that it shuts down with a warning? No, never. But the phone does get annoyingly hot, especially when charging even if I'm not using it at all. That's the phone plus the weather in my country isn't helping. Phone regularly touches 40° according to battery guru, when charging can go up to 43°.

On WiFi things are very normal. Mobile data however is a very different animal. It you have poor signal especially expect this to get pretty hot. Like stated above though, not shut down hot just hotter than what I consider normal. 35-40c battery temps on stock with those conditions isn't unusual.
Initial setup for sure gets toasty as well.

For whatever reason (latest updates maybe?), I've noticed recently that not only does my 6a not overheat, but the battery consumption has dropped significantly. At my admittedly low level of active usage I can easily go two days and still be over 50%. I might try for three full days soon.

I dont have any problems with overhiting , i have phone about 30 days. Playing games recording at 4k no heat problems at all.

Damn bruh...another 'overheating' thread?
Yes. The 6a may get fairly warm in some specific use cases, but it doesn't actually overheat as in start throwin' out warning messages and start throttling or worse, crash/reboot that I've ever witnessed. Actually mine seems to run slightly 'less warm' since A13's beta 2 & 3...just before I flashed a custom kernel. A few things to consider besides differing usage scenarios. If you're using a case, it may not only hinder cooling a little but probably 'feels' less warm due to the insulating properties as well. I try to go with a minimalistic case...it may not provide a lotta cushion if dropped but I'm hoping the improved grip offsets that point. And ofc the thinner the skin to less it retains heat. I went with a grippy Spigen Liquid Air or something like that.
Above all, I keep in mind that the 6a has the same processor as the [email protected] P6 PRO and that also helps me to forgive n forget that it can get toasty at times...plus thst resulting Tensor 'grin-factor' tho...
...just my 2 centz ofc

If you're using mobile data or using the phone as a hotspot thing gets very warm.

Normally, I've only experienced the phone getting very warm when I'm playing a game and charging the phone at the same time. However, on a recent trip to a foreign country, my phone (and its camera) stopped working because it was hot outdoors (around 80°F) and I was outside for 30min or longer. My friends' iphones didn't overheat though.
I haven't experienced any signal problems.

Mine never overheats. Its just warm enough to be a hand warmer, but not enough to damage anything

...and it displayed an overheat popup warning? 'cuz it was 80F outside? I've been out with my 6a dozens of times in 80F+ weather and NEVER had my phone throw an overheat warning much less shutdown or lock up. You might have something wrong with ur phone if a warm day kills ur phone...js

No overheat warning. Phone felt very warm, froze up and apps would barely respond or it would keep on rebooting. Tried a few times to power off, wait a minute, and then power on to get that last photo, but didn't work. After I got out of the heat for a short time, phone went back to normal. Felt hotter like 95 degrees, but weather report said 80s.
Nothing wrong with my phone per se. My guess is that my phone was in direct sunlight for 30 min. I myself was dying from the heat. And before that, I was already taking pictures on and off for an hour (in the heat but not direct sunlight). I've used the phone before in hot weather without issue, but this time around, it was continued use and in direct sunlight.

My 6a definitely overheats and shuts down sometimes without warning. This has happened numerous times even when the phone is having light use (chrome or connected to android auto). I would say there are 2 factors. When the outside temperature is hot (35c or hotter - which currently in Australia is a daily occurance) and when the signal is not strong (also a very common occurrance here) - when this happens the phone can overheat and shutdown within minutes even with little use.
From my exp. signal strength seems to be the biggest issue. The pixel seems to literally burn through the power when signal is weak and get hot.
Generally I have had a 50% chance of getting a 'Your phone is hot' warning - other times it just turns off.

You should RMA the phone. Sounds like a faulty device to me.
Also, just hot ambient temp does nothing to a phone. If it gets direct sunlight, thats unsafe for the device because of how hot it can get (if you measure temp in your car, it gets up to 60-70C+ easily.) If I use my car in hot sun, I aim an AC vent to its back and then the phone is super chill all through the ride.

Yes, I think I will RMA it. - I don't agree re ambient temp. My phone certainly seems to shut down more often when the ambient is hotter. Also, re the car. I had the phone in the glove box which is separately cooled to 21c and even then it would overheat, - I suspect related to poor signal. But yes - will RMA it.

Try safe mode first. You may have an app which is misbehaving. I've never had my 6a overheat, it will sometimes get a bit warm when charging, but that's it.
