S8 overheats - Samsung Galaxy S8 Questions and Answers

It's 950U1 unlocked version. Battery life has been very good and No overheat until today. But today, I charged it to 100% and disconnected from charger and used it for over an hour, then i suddenly feel the phone was very hot - never this hot before. And I noticed battery dropped faster than usual. I then restarted phone and heat went away.
Anyone had similar overheat issue? Could it be Google play services behaving badly?

[Q] Phone got very hot and battery drained in 2 hours???

So my new Note 3 was fully charged this morning and when I got to class I noticed it had heated up A LOT. It was very, very warm. I had all the apps shut down, Mobile Data turned off, Wifi turned off, GPS/location services turned off, etc and it still died in 2 hours. I was concerned because it was heating up very hot too, so I took the case off and as soon as I returned to my room I plugged it in. The battery went from 100% to 2%.
Why did my Note heat up like that and die when nothing was currently running on the device? Help!!! I don't want this to happen again :crying:

That sounds extremely wrong. I would return it personally if something like that happened to me. My note 3 has never felt even the slightest bit hot to me. It could be something you downloaded, or a crazy app doing something in the background. but for a 3200 mah battery to drain 100% to 2% in 2 hours seems like something is faulty.
I cant even drain the phone that fast on purpose if i tried.
Agreed , just return it or warranty it .

There is an anomaly with you phone. I've had this problem before but on a Motorla Droid Bionic. I was tethering while on a custom rom and my battery went from 96% to 2% in 2 hours. Sorry if it's off topic, my JuggerNote3 has not had a battery issue like you mentioned, so far. Best of luck of getting a replacement and fixing your battery issue
Thanks everyone - I am going to try and fix this problem. Additionally, my phone has also restarted 2 times. This concerns me as well. Does the Note3 need to update by restarting? If not, then I definitely have a battery problem.
My phone is fine now
SO I never got around to doing anything about this problem, and it never happened again. I've had this Note 3 for about 2 months and now it's fine. I met a guy who also said this happened to his N3 (more than once) but his phone still functioned fine. So it seems like maybe it got overworked too soon after I got it??? I'm not sure but it's all good now! I absolutely love this phone, and would recommend it to others. Looks like I'll be a Samsung user from now on

98% deep sleep but 48% battery drain? What gives!

I charged my phone for a little bit last night because it was a little low (48%). I took it off at about 77%. I don't understand what happened. Why did it just drop like a rock? Phone is AT&T LG g2, stock 4.2.2 rooted.
Jesus that can't be good.
I have no clue about this one; it's just too weird.
I'd probably let it fully deplete and then completely charge it and see if it ever does it again.

That's what I'm going to do. Unfortunately this is not the first time it has happened. This happened about 2 weeks ago, but then my GSAM showed a HUGE signal decrease at the same time my battery drained, so I figured it was just that.
This time I just do not understand. I've had this phone since August or September and it's been great until this randomly started happening in the past couple weeks.

Well it says 66% of that was phone radio signal. So that is the problem 90%. I had similat problem only it was while charging, so my phone wasnt charging almost at all, when i restarted it was charging fine (from 20% to 100% in 90 min) . What happened when u picked it up, was it still doing that? Or maybe its a some kind of cpu loop if that is even possible. Some people was complaining about nexus 5 rapidly discharging with combo of some lite apps (news readers).

Yes even after picking it up, the drain continued. I've let it die and am charging the phone while it's off but I don't know if the problem will be fixed.
The youtube app was causing a major battery drain for me a few days ago,now I close it after using it just in case . I'm in the habit of checking the phone's temperature at all times :/
it has a great battery life, especially sceen on time, but the standby isn't top notch at all, I think it's poor software optimization on LG's end, I hope 4.4.2 fixes it.
charge till full. then reboot and check battery percentage.

[Q] Heat problem

Hello,
This night I left my phone plugged in to charge it.
When I woke up 6h30 later, it was boiling hot and not just hot like the times I play games on it. It was hot all over, front and back!
I unplugged it and the phone switched off by itself.
I waited 15 minutes for it to cool and then switched it back on.
It's working fine but I'm afraid it's lifespan has been dramatically reduced.
I've attache the battery settings screen after the incident.
Apparently, the phone charge blocked something like half an hour after being plugged in and the overheat lasted 6 hours...
And the security system activated only after unplugging.
My questions :
Do you think the phone could be badly damaged?
Is there a way to check the battery temp history?
If the phone still works fine, should I still give google a call?
Thanks
I've been experiencing hear issues lately as well. I looked into weekdays running in the background and what is keeping my phone awake. Tweaked a few songs here and there. So far it hasn't been getting quite as hot, but it's just my first day results.
A while ago I was using a third party charger overnight from 10% or so. After roughly 6 hours it was only at 49%and screaming hot. Changed up chargers since and haven't had that issue.

Use the charger provided along with the device or one with a similar ampere rating for best results.
and for your above battery issue try to switch off the device and charge, see if that helps. If it's just a calibration issue then it'll be fixed. Otherwise you'll have to get the battery replaced.
dont let phone on chrging whole nght.. it effets btry life.
I had an issue with my battery and heat. The phone was getting warmer every day (or week).
I noticed that their was a little bump on the back cover. After having removed it, i realized that the battery had nearly doubled its size.
I purchased a new battery (original), and i don't have any heat issue anymore.
The old battery was a year and a half old.

6p and 7.1.1, battery life is better buuut

The battery life is waay better. I used to play games on my 6p and the phone would get really hot and the battery would die very quickly.
With 7.1.1 i have just played non stop knight for over an hour and im still at 70%. The phone only gets warm but not hot.
The processor seems to be running slower though, i noticed that it was lagging more often when gaming.
Has anybody else noticed this?
Maaaybe... im like you.
well this is disappointing.. when on 7.0 i my phone was turning off at about 15% battery left. Today my 7.1.1 6p turned off at 15%...
This just started happening in the last few weeks.

Tab E Stuck Overheated. Please Help

Okay so I'm getting very worried here, but I got my tab e about 15 days ago, meaning I'm one day to late to return it.
And earlier today all of a sudden the upper area of my tablet where the charging port, camera, and samsung name started getting very very hot, like to hot to touch hot. And it's been like that ever since, like 5 hours now.
I had it off for almost an hour, how hot it was never changed.
I let the battery drain till it went dead thinking if the battery was empty there wouldn't be power to heat anything up.
Made no difference, or any change what so ever.
I have no idea what's going on here and it's gotten me very worried as I said up above.
Everything still works perfectly, but the battery drains so fast.
Please tell me someone in here knows whats wrong. And please let it not be that my tablet is defective, cause as I said, can't bring it back as of today.
Sorry, I don't know how to solve your problem without more information, [installed battery draining apps, heavy video or screen usage, gaming, etc] but unless you rooted it, you should be covered under warranty even if you can't return it to the store where you bought it. Even if you are rooted you may be able to return to stock and get a warranty return through Samsung.
Same problem
I had the battery replaced done but it seems to be getting hot again
When i let it idle overnight from 91% 10pm and when i woke up this morning the it dropped to 0%.
