If you Galaxy S device has overheating problems then you might wanna take a look at this.
There are a few reasons why this could be happening.
If none of these reasons are your problem, then I suggest you go to the nearest Samsung store and / or to you carrier's store and ask them for help.
If your fast charging is on, your device may overheat, but only during charging, so don't worry about that (it even says in Settings).
1. Battery has been through stuff
Your battery may be failing or has not been treated well. This often happens when your device has been exposed to direct sunlight at the high temperatures (I say over 30 C). The other reason could be that your device has been in a very cold place (Idk if you put you phone in a refrigerator LOL), but that's very unlikely to happen.
2. Water, water, water
Some Galaxy S devices are waterproof / water resistant, but some aren't. You see, I have a Galaxy S6 and it fell in dirty water. I had to change my battery. If this happens to you there's a 50% chance nothing will happen, but there's always that other 50% that may occur every time, every day.
3. Software problems
There may be a software problem, but that's very unlikely to happen. Although I have something to say about that. So, my friend has (still!) a Galaxy S3. He had some kind of a kernel fail, so we had to reflash his kernel.
4. Left on for too long
I know this usually happens with iPhones, but can also happen with an Android phone. If you leave you phone powered on for too long (and I suppose charging it), there may happen a software failure that keeps overheating the device.
5. Xposed
This is happening to me when I have any, but seriously any Xposed module enabled. I noticed also if you have to much, a similar thing happens. I would buy another phone if I'd use Xposed.

Hello! Long time lurker, although I rarely post.
There are some rumors floating around most posts that pertain to charging about the fact that if you leave your phone charging on android you can destroy the battery. I feel this is a VERY crucial issue and have yet to see a firm answer supporting either side (done LOTS of searching )
I think there should be a dedicated post to informing people of whether or not this is true because its a very key issue.
Side note: Been using android exclusively for 2 weeks now, and leaving it charging overnight and dont think anything bad has happend. Thank you so much to all the devs, especially to cortulla and darkstone. Youre the best. <3
UPDATE: The general consensus so far is that even though the battery kernel may or may not be fully functional, the hardware should be capable of keeping anything destructive from happening. :] a professional opinion would be greatly appreciated
i always leave mine connected overnight next to me, havent exploded yet...
In my opinion, even if kernel will be faulty (im not saying it is), charging cirquit still have hardware protection, which will block overcharging battery..
^^^ my sentiments exactly.
Plus, my hd2 gets slightly warm while charging, but seems to cool down when charging reaches 100% (or 91%, or 98% or whatever Android decides is a full charge today )
either way, it seems like the either the kernel or the hardware overcharge protection is doing its job for me.
(That being said, I have just 5 minutes ago, unplugged my hd2 when it got to 100% just to err on the side of caution lol.
now - 5 mins of standby later, its down to 96%! WTF? lol)
'Charged' from 96% to 100% in about 30 seconds though
So maybe, charging/battery status shouldnt be fully trusted just yet
I don't think so. But it's bad for your battery if you let it completely drained.
I've got a second battery. So I don't care if they get damaged Android on the hd2 is worth it.
sent from my hd2.
I don't know think that it would explode, but there is reason for concern. I did exactly that, and the next morning I woke up my phone was hot to an extreme. I posted a thread in the Q&A's about this yesterday morning. Now after I found the phone in that condition, nearly 3 hours later the phone booted on its own to my suprise, I was ready to summon HTC lol. So yah I think there's something there are mechanisms that protect the device from such peril, as I witnessed this myself.
There are hardware measures in place to prevent this from happening. Google ds2745.
I leave my phone on charge all night anyway, never had a problem.
I have always charged my phones overnight. Never had any issues, although between work and personal the phones generally need a charge by bed anyways.
switch it off
unless I'm expecting a phone call i always switch off the phone then charge it.
it won't get hot that way, and when you switch it on its a nice clean reboot no matter what os your using
I noticed that there have now been reports of the S7 and S7 edge exploding in the same way the note 7 has even giving a guy 3rd degree burns. This got me thinking about the two s7 edges I've had and the quality control issues that may be plaguing our devices as well. My first s7 edge had great battery life, 6 hrs+ SOT, and ran cool all day. I then returned it because a better promo came out within 14 days of my purchase and got a new one. The new one has never made it past 3.5 hrs of SOT and runs hot all the time. This is with the exact same apps installed, the same settings, and initially the same firmware. I've tried running 100% stock, FDR's, freezing apps, rooting, and tweaking just about everything with little to no success which makes me wonder if this is a hardware related issue with the battery. Maybe this explains how some people are getting 8 hrs of SOT while others cant make it past 3. It's a definite possibility in my mind that we have the same or similar manufacturing defect in the s7 edge as the note 7.

I've never gotten anywhere near that much screen on time. Mine's more in the 3 hours range maximum. If the screen is off, my battery seems to decently, but I've never seen the crazy high numbers that many others have.
My SOT is rather high, but I only experienced battery issues after rooting the first time with the 935V kernel. After moving to 935U, I went back to VERY cool CPU & Batteries, and better SOT.
Hot S7
Try turning off all of the Amazon crap if you don't use it. They tend to use up a lot of battery time when they are running in the back ground, and by default they are installed and set to run always. That might help a little bit.

Google any device and you'll find cases of a few burning. That's just the state of LiPo technology at the moment.
The Note 7 has had upwards of 30 cases in a very short period of time, and a known quality issue from a particular manufacturing partner. What you'll find with the S7/S7E is nothing near that severe, and on par with contemporary devices like the iPhone 6/6s.
Update: I called Samsung and I'm not even kidding here's how the first part of the conversation went:
Me: Hi I have a galaxy s7 edge and I'm a little concerned because it is draining quickly and the phone runs very warm and sometimes hot.
Agent: That is not good! Are you hurt?
Me: No I'm okay
Agent: Thank god! Please power the phone down and send it to us. We will fix it or send you a replacement within 5-7 days. What is your imei number and email address?
I got an email within 5 min with a return authorization and then called verizon because I don't want to be without a phone for 5 days. I told them the story and they are sending me a replacement and I just have to send the old phone in. Either Samsung is being super cautious or they know there might be an issue with our phones as well. Either way I'm looking forward to seeing if the replacement is any better. I saw that a couple of people have reported getting referb phones that run cooler/better.

i believe theyre over 90 now lol.. i doubt theres a defect in the S7/S7E, ppl are just wary now after the N7 recall even though unless you do anything crazy theresasmaller chance of it atually exploding..
i actually take my phone off the charger for a few mins if i feel it burning up lol
My phone has been doing this. Getting super hot and the battery goes from 100% to 0 in 2-3 hours. I'm gonna call them

If I remember correctly they had a factory issue and had to outsource like 10% of the note7 batteries to a different company. They didn't do that with the s7e to my knowledge so if there is an issue it's probably not related to the note7 issue.
I had this issue earlier this week.....phone wouldn't even last a normal 9 hour shift at work and I was down to under 15% by my lunch break. Lost my mind going back to stock and reflashed stang Rom 3 times...the third time I forgot to install greenify and the problem was solved. Reinstalled greenify and my battery drained like it was a countdown clock. Went back stock, reflashed and didn't bother with greenify, just rolling with forcedoze and have 0 issues. Currently at 32% and I've been off the charger for close to 12hours and even had to use my flahsight for a solid 10minutes
My original Samsung Galaxy S7 Edge ended up literally melting all USB cables and chargers that I plugged into it. This was roughly after 4 months of owning the device, it always got really hot while charging, but one day it started smelling like burning plastic. I successfully got a warranty replacement on that device, my current S7 Edge still gets hot after charging, but nowhere near the original device.
I would venture to assume that 'fast-charging' is the culprit behind overheating, as you are pushing 2 Amps to the battery (compared to your usual 700mAh - 1 Amp standard USB charger).
As the Doctor stated -- you will always have SOME defects in a very small percentage of devices. As the S7 Edge has been out longer, I would say we are okay
TL;DR: can overheating affect life of phone?
Hey all! I previously owned a lg g3, and it used to overheat as well. After about a year or maybe year and a half, one day when getting hot it rebooted and then wifi/Bluetooth stopped working.
A few forum searches suggested the chipset warped due to the overheating over time. I haven't actually opened that phone to verify but makes sense.
So as we know, the camera throttle issue got fixed on the Moto g4 (at least the camera works flawless for me even when overheating to 120F). But my concern is less the camera performance now and more so the life of the phone after constantly overheating. (I have kids so I'm constantly using video / letting them play games, so it's overheating once every day/two days)
The chips are rated for very high temperatures - like 90C internal. That would translate in something like 70C external, you cannot held the device at that temperature. What you are calling "overheating" is actually normal temperature for this kind of electronics, it doesn't affect the functionality.
But sure, things can and will break sometimes - regardless of the temperature. I would use the phone intensively while in warranty period, if an electronic part is to fail, is more likely to fail at the beginning of device life.
Hello, I just bought an S8 as an upgrade from my beloved S6E+. when I firt turned it on the phone was on 55% I started using smart switch to transfer stuff from my old cellphone over WIFI (over 10gb of stuff) while the phone was updating from the playstore and downloading a software update and updating galaxy apps (too many stuff) I felt the phone getting really warm then it became HOT not uncomfortably but very very noticeable.,I downloaded an app to see the temp. and it reported 59 C for the CPU and 42 for the Battery. then it jumped to 69C for the CPU and 47 for the processor. I waited till everything finished, updated the sofware and reststed. it idled at 42 - 45 C.
I live in a hot country and the outside temprature was 38 C. but my S6E+ never reached such temperatures, and I don't want to bring any drama but the whole Note7 thing is making me paranoid about using the phone while its hot like that. so is this normal??
1. The fact that you're living in a hot country matters. Its a factor. Coz apparently ambient temperatures affects the feel of materials such as glass or Aluminium. So take note of that.
2. You've said it yourself,you made the phone go through a hell doing stuff all at once. Let it settle. Give it days,maybe weeks.
3. If after all that you're still experiencing the overheating,then it could be;
a)Just a software hitch which could be fixed by a simple factory reset or software update.
b) If someone else report the same issue,then it could be a common issue with the phone
c) If no one reports similar issue and yours persist,then you probably have a defective unit,and you should consider replacing it.
Hello.
Today after i was back from town, I left my S7e in my pants pockets while i changed clothes and opened my pc. I tried to check whatsapp web from my pc, and it told me your phone is out of range(out of battery in this case). and i was like oh well ok, its ran out of juice. Tho i was a little suspicious about it, as it was at 20%+ while i was at town, out of experience i know that 20 lasts a long time. But, i forgot about it and was too lazy to get my charger out of my backpack.
Now after about 2,5 hours i quit the stuff on my pc, moved up and got ready to charge the phone again.
And HEH HEH its bricked. Or optionally the screen is totally dead, wich i think is not.
Have not flashed ANY roms on the device, have had a stable root and stable xposed and stable everything since note 7 launch. Never had any issues.
So, what do yall think?
If the battery dies can it cause this? Havent had any water contact or anything with the phone today.
its dead even when charging?
if yes thats not battery fault.
there is a sticky thread for bricked S7 edge, try that.
or maybe you hit your phone and it died?
Lithium-Ion batteries don't like having less than ~40% charge. You said that out of experience you'd knew that 20% left charge lasts a long time, suggesting that your device has been run below 40% of capacity quite often.
For me, this indicates a dead battery that is no longer capable of delivering/holding a sufficient current.
it should work on usb even without battery, like notebooks.
dead battery just dont hold energy and capacity

Not necessarily. Most, if not all modern smartphones will not turn on with a malfunctioning battery.
I tried it out of curiosity. I have a few devices lying around.
Trying to turn them on without a battery:
LG G4 - negative
LG Nexus 5 - negative
HTC One M7 - negative
HTC One M9 - negative
Samsung Galaxy S3 - negative
Samsung Galaxy S4 - negative
Samsung Galaxy S5 - negative
Samsung Galaxy S6 - negative
Samsung Galaxy Note 3 - negative
Samsung Galaxy Note 4 - negative
thanks we learn every day.
mostly devices that I repair turn on just on cable, but I dont ha e a lot of experience with modern smartphones - mostly lcd replace.
I had the same problem, I was sending a TX message on my S7 Edge and all of a sudden the screen just went blank. The phone wouldn't turn on or off and it was getting hot. So I booted into safe mode, now the phone is in safe mode and won't boot back into a normal operating system mode. Now my S7 Edge is stuck in safe mode. I can move through the different options, but the phone will not act on any of the power options
