[Q] battery overheating question

hey all, maybe its just my paranoid self, but i just want to be sure;
i was charging my phone, and at the same time, i was playing slice it. suddenly i realized that the back of the phone was getting really hot, and i checked the temperature. it was about 45c, and i was gettin freaked out, so i took the batttery and put in the fridge for like 10 seconds, before realizing that was a stupid mistake. after about 5 minutes, it cooled back down to 30.5c. i believe that perhaps the battery was around 45c for about a minute or so.
I was just wondering, do you think my battery life will suffer from my idiotic antics? Im a bit worried that itll have a significant impact, even if it was for a few minutes? Did i 'burn' out some of the lithium ion cells?
much help appreciated!
thanks alot!

Just curious, does only your battery get warm, or does the top half of the phone (above the battery) got hot too?

Phone only overheated when I had bluetooth and wifi running while charging

its just the back of the phone where the battery is located

Mine did the exact same thing last night with fruit ninja of all things. I also put my whole phone in the fridge for one minute and it dropped the battery temp from 45c to 38c. The battery condition also said "overheated" instead of "good" which it has said since then.

nice to know that im not the only one :]

Can anyone answer my question about if the short amount of overheating damaged my battery?

Mine got to 53c while doing absolutely nothing, any idea what causes this?

I don't think anyone really knows and begging for an answer is a quick way to get flamed.
I know that if you were to rapidly cool metal or another material in that same manner, it would crack. I don't know if that same issue would apply to batteries. I definitely wouldn't put anything overheated directly into a frozen environment like that.

+1 not a great idea, just take battery out and let it sit

Mine had the same problem. Whenever i put it on charge it would heat up within minutes and then upon unplugging it would cool down. I read somewhere in the forum to discharge completely and then recharge to full. I did that and its been 1 week since that and no problems with overheating and battery life is also improved. My battery`s health is still GOOD i checked using * # * # 4 6 3 6 # * # *
Hope this helps.

I undervolted the cpu. Overheating almoat stopped. I swapped battery and has been better since. Usually running two quadrants i would start feeling it get hotter and hotter. On new battery i run four an don't notice any major change.
G2x with CM7 and trinity kernel

out of the blue overheating
My phone was awesome...but now it overheats....??
I am going to try and undervolt and see if that helps my problems but my phone just goes crazy hot when it's asleep and idk what to do, even w/ a new warranty phone, and i could tell it's new cause it still had the green tap by the buttons and stuff...the old one got crazy hot, but only after cm7 build33....and this was also after i changed the recovery to 3101 ext4 supported one....can a recovery affect your roms (overheat it) i would't think so, it only loads on command idk how it would....hmmmmm my vibrant would be a dead cold 28-29c when on idle/sleep but w/ this phone it just gets hot and is about 37-43 when doing nothing.....i'm going to try the undervolt thing w/ cm7 latest build and faux123's kernel 0.1.1 and try to undervolt it, i'll search thru that thread for good undervolting starting points...and play w/ that......idk i'm just confused why it is just now happening and not before, i had it on launch day and no problems till last week....i'm lost..

[Q] Is yours getting warm?

My sensation is getting warm @ the bottom while using (normal tasks: messaging, mail).
It's not hot it's slightly warm. Anyone else having this issue?

Yes, although it doesn't seem as bad today as it was yesterday.

apparently if you turn off Wifi, you problems will disappear! Lol. Joke.

Mine has only gotten warm never full blown hot. Usually cools right back down. I figure it was just the dual-core working .

Mine gets a bit warm during moderate/heavy usage but I would say it's normal..

yeah, i was about to post.
Mine is very warm, as soon as i use it, it begins to heat, up to 109°f (43°C) when i use internet.
Using only mobo player, it's a stable 103°F (39.5 C)
it's very hot, i do not understand.
I stopped a lot of background sync, no difference...
any idea?
edit: btw, big battery consomption...

I would call for a replacement battery if it's that bad.
I haven't had any issues...though keep in mind I'm coming from a G2X that would burn my hand off.

My Sensation has been running very hot right out of the box. I have had it for a little more than 26 hours and it concerns me how hot it actuallly runs. Also just a few minutes ago I started getting a notice that the device had reset in an improper manner and asked if I wanted to report it to HTC. This has come up twice in the last 2 hours. I had the device setting on a table in a restaurant and thought i heard it do something now I know it was rebooting itself. The very high temps continue. I have a G2x and have not had all the issues other are reporting although it does get a little warm 96 degrees at times. I am at the point where I am going to take the Sensation back and wait for a short time and see if more kinks are worked out. The Sensation is a marvelous phone and will be almost untouchable if there are a few software updates to fix issues. Just do not want to wait like I have and did with the G2x and try to put up with overheating etc. I do really like the Sensation though.

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.
Sent this sensational message for my sensation

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

How hot gets your battery?

Mine, after about 25 mins of use - gaming and surfing on the net - reaches 44 degrees celcius and bottom of the phone gets really hot.
This happens in normal use not while charging.
Is this normal?
What temps do you get?
Also I am experiencing signal drops for the gsm network, but I do not think this is related to heat issue.

Same here, it gets too hot to comfortably handle. Tmo is sending me another as soon as they get them in.

Doesn't get that hot for me with hours of use gaming, surfing, playing music, etc. But yesterday when streaming music via 4G, charging in the car in the sunlight (N1 dock power cord), without the ac on on a 90 degree Fahrenheit day the thing was easily 100 degrees F. Hope it's just an issue with the charging cable and heat of the day combining.

mine has reached 113 degrees F just from playing peggle for around 20 mins...

Around 87F on average usage unplugged...

got to 110 degrees playing Cut the Rope

Mine reached 50°C while charging and an active app that kept the screen on. Outside felt cooking hot when I picked it up.

Mine got to 113 deg after only 10 min of playing fast five...really worries me as this is my second unit, first one was perfect built, no batt issue bt the power button was crooked than a MOFO lol..if this continues i mite return this one too, bt then I worry about getting another unit that has another issue...its like u can't win with this things

My wife's got hot enough today to shut down while she was using it.
I'll be playing with it tonight for a while and see if it was a one time deal, mine doesn't have that problem at all.

your new phone doesnt have the crooked power button? i thought everybody had that

Had a file transfer going while playing some games - ended up at around 50c with the bottom of the phone extremely hot.
When i stopped things and tried a reboot - phone went into a reboot loop - so went to pull out battery to hard reboot. With cover off -- very hot - not just battery but area with SD card / SIM is too hot to hold.
It would definitely burn my fingers if I tried to hold there.

Dammit, mine is also getting pretty hot. I wasn't even playing games on it when I noticed how hot it was getting. I was showing my family a few pictures on it, and in 5 minutes the lower part of the phone became really hot. Never had that happen with any other phone before. Hmm...

haha i thought the same too until someone posted a pic of their "normal" one and i was like hell nah, im returning mine for a diff one, which now has a perfectly level power button...problem is though that first one had no problems and the batt never got hot. this second one's issue is the batt gets really hot after a few minutes of usage in which the phone gets uncomfortable to even handle.

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.

I still think it's normal as I've seen the same thing on two different S6 Edge phones.

My S6 overheats too , it's annoying and sometimes even scary.

I've just received a replacement phone. It heats up the same as the old one. It would be so much bad lucky to receive two broken phones. I will assume it is normal and live with that. But I'm not happy with it...
