[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.

[Q] How hot is too hot?

Yesterday my G2X was really hot it was over 110 because of the weather... So how hot is too hot and what to do to protect the phone when you have to be in sun? Any advice?

I have same problem. Its 110 in Vegas and there is not much you can do.
G2x with CM7 and faux kernel. NONSENSE!!!!

I was at a outside event and my phone was at 119°F.

Mine was at 120f sitting on my desk at work. Considering a swap.

My phone gets hot sitting in my truck dash mount streaming music, then again I live in Florida. On a side note it doesn't get hot at all playing drag racing for 4 hours straight.

Here is what LG says:
Humm... Max Storage temp is about 122F, so I'd be careful about leaving it in a hot car during the summer, especially in direct sunlight. The Operating Temp is about 113F ...
There is Thermal protection built into the phone so if the heat gets excesive, it should shut off, But personally I wouldn't push it to that extreme. I use a little app called "Battery Indicator Pro" that makes it easy to see what the reported temperature of the phone is.
If the phone is uncomfortable to hold, then it's too warm... Remember, Heat is NOT a friend to Electronics of any type.
If your phone is getting too hat to hold, I'd contact T-Mobile or LG Support about getting it repaired / replaced. LG can be reached at (800) 793-8896.

I noticed mine was warm (about 40c) when using my data and just surfing. When it went up to 45c, I turned the data off immediately. I let it sit for a little bit and it went back down to the 20s.
It was the first time it got that warm so I'll chalk it up to the weather.

I had mine in my car while I was driving around running some errands 2 days ago. It was 101 degrees outside, and the phone shut off...when I turned it back on, it said it was 125 degrees...I"m guessing that was too hot. I haven't noticed any indications of permanent damage, so I guess the safety feature worked.

I hit 122°F today and phone lock up. Keep phone out if heat. LOL

[Q] Battery overheated. Single phone issue or major issue?

I received a samsung charge yesterday from Asurion (Insurance through vzw) and after installing the latest 12-11 release post ee4>ep4 ota and odin, while phone screen was turned off in my pocket, I noticed the phone starting to get a bit warm. Next i noticed it starting to get hot as hell.. pulled it out, and yes it was excessively hot. Pulled battery, allowed it all to cool down, water marks were clean, no bulging to the battery or burns to the device. I then put battery back in, and turned it on. Noticed battery went from the 38% it was at, down to 7%. Has this happened to anyone else or just me?
Thanks guys,
Drew

That's definitely not normal. I'd flash back to stock, see if it happens again, and if it does, exchange both battery and phone.

It could be a phone problem, but it sounds to me like there is (or was) something running in the background that was causing drain. Any app that grabs the GPS and doesn't let it go could potentially cause this. Facebook is an occasional offender for me.

are you using the official fb app? and I had gps turned on for a bit last night, but cant remember if it was on during this time. Since that happened, it has been off, along with wifi
EDIT: Asurion just called back and one of the ladies in the asurion client relations dept will be overnighting me a NIB charge. We will see what happens with this. Had nothing but problems with em so far, so I expect something to happen to the new one as well. We'll see though lol

Have you had an app cause overheating like that with the screen off? The only time I've had my phone get really hot was when I was oc'ed, with the screen on and sitting in the sun for an extended period while I was using navigation.

My phone heats up with the screen off if i have no service.

I am using the official app, though I haven't had the new one long enough to really make any observations of it. It was hit and miss. But, no, I can't say that I've seen temps like that, ever, except maybe once or twice when running in a car dock, in the windshield on a hot day.

How warm do you guys let your phone get?

Hi everyone,
I'm about a week-long user of the M8 so far, and I'm loving it. I've been a fairly long time HTC user as well - I started with the Ozone, then fell back to a feature phone until I picked up the Incredible 2, which lasted for a long time.
At any rate, I'm no stranger to hot phones, literally. During my commute back and forth to work, I would use my Inc. 2 to record the drive with Dailyroads Voyager, while simultaneously monitoring road conditions with Waze. My good old Inc. 2 would power through those tasks like a boss, while at the same time burning up, and usually unable to pull enough power from the car USB charger. The only way to keep my phone stable was by running my car's defroster to blow cold air over the phone.
Now that I'm up to date hardware-wise, the M8 is no exception in the power house category. It can even keep charging while it's doing these things, although it does still get pretty warm. It's currently in a protective case which seems to dissipate the heat pretty well.
My question is, how warm do you guys let your M8 get? (Note: I'm rooted, but still running stock with no sort of overclocking involved.)

The only time I've ever had heat issues was when I mounted the phone to use as gps. And this was under direct 90 degree heat. Other than that, I've had no problems with heat whatsoever, even on prolonged lte usage and video watching.
My experience might be isolated though. I'd say, if your phone is uncomfortably hot to touch, you should probably ease up on it to be safe.

Yeah, always with the GPS navigation it seems. I wonder if this is something that can be fixed software wise (I.E filling a bug report to Waze/DRV), or if it's more on HTC's end for software/hardware...

I would assume it was just the metal body absorbing direct sunlight but I might be wrong. My HTC rezound used to double as a portable heater the way it used to get hot with extended usage. This one doesn't seem to be like that though.

Usually only heats when running tether for a period.

That's been my experience from the Inc 2, as well. So it seems like the mobile radio may generate quite a bit of heat...

I recently accidentally let my M8 get too hot while listening to music with it laying in direct sunlight face up. Didn't think about the black screen absorbing so much heat, got so hot it went into safety shut-off. It was almost too hot to touch, but after a couple minutes off it was relatively cool and turned back on fine with no problems or battery issue.

Low 40s Celsius is when I start to get uncomfortable. It's still safe, I just simply don't like it that warm. I get mad when my OC'd Intel cpu hits 60c even though 75+ is fine. I'm just anal about temps I guess

I agree that the only time (and it was only once) my unit got hot was while I was using it in its car mount and GPS was on. Otherwise I have seen none of the heart issues that plagued my Rezound and my Incredible.

I usually put it in preheated to 400 degrees and flip halfway through at 10 minutes.

If you're rooted, install XPosed and than install "CPU Temp in StatusBar" to keep really good track of the temps. Mine doesn't ever get over 110F, even under hard WiFi and streaming use. I've never used it for GPS in the car. At idle, it sits under 80F.

Thank you, I've been looking for a CoreTemp-like feature for my phone. I'll give this a try!

I've been hammering on my new m8 (swapping roms, installing massive amounts of apps, running tests, playing games ) for over a day and the phone has never gotten beyond lukewarm. Nothing close to what my m7 used to do

I never look at the temp. It will auto throttle if it gets too hot anyway. Just use the phone how you want and don't worry about it...

Well, I gave the temp monitoring thing a try (very cool!) and I don't think my phone ever passed 65 degrees Celsius, which I guess is ok. So no worries it seems!

That's a hundred and forty nine degrees F. Lol you need more ac.
