I'm running on Android 8.1. This does not annoy me as often but when the phone is charging while feeling a little bit warm, it shows a high temp warning then slows down the charge. A second later, it shows a normal temp and resumed normal charge speed notification, then it shows the high temp warning again..
It's annoying especially when I connect my phone to my laptop and use it because the repeating high temp low temp warnings keep popping up.

Sounds like an issue. Try different cable. Also factory reset. If those do not help, you should bring it to where you bought it from. This might become dangerous (explosion scenario). Also, you are degrading battery incredibly quickly while having it at high temperatures.
This is a common thing, it's because it's charging. It's also stated in the Support app that comes with the phone. It's normal it's heating up when using while charging. Nothing is wrong with the phone.
It was annoying me too, so I just disabled the app. Or maybe I had it backed up and uninstalled with Titanium backup. Either way, no more stupid warnings.
Yeah I only experience this issue when I was playing heavy games then after that I'll put my phone on charge while using it or playing games

I've noticed it previously during usage (like on the internet while having MSN running, or while playing games)
but I just got off a phone call which lasted about 20 minutes, and the front (and back) of my phone was just too warm for me to ignore. I would have suggested that it was the heat from my cheek against the phone but that wouldn't explain how the phone was quite noticeably warmer than my cheek.
The backlight wasn't on (i doubt the LED backlight would cause much heat anyway).
Does the mega have any internal temperature sensors like PC's have? And any software to read them?
My previous phones NEVER got this hot on even hour long calls,
and mix this with the fact that at my work one of the PDA's blew up a few weeks ago (was the battery), it just makes me that more paranoid!
I am going to Hard Reset soon anyway as things started running a little slowly recently, I hope it will also stop any hidden processes that may be running in the background and overworking the cpu. But I would still like to know of any software

I think its pretty normal to heat up during long conversation. Their manual also says "Using any function for long time will heat up the phone", but only upto a level.

i've never experienced warming of the phone which is coused by operating it , well maybe just a lil utube watching for an hour but it was warm of my hands , i'm only worried when i leave it charging and after 15-20 mins LOL ! the phone is HOT i know that is normal , just sharing opinion
Heat comes from 2 sources in general external and internal.
External is from sun, your hands or phone in your pocket. On longer run this is not good for battery life.
Using navigation in your car during summer can run your phone real hot and feels quite uncomfortable! From a 20 min call it should not. But this is subjective.
Internal heat is caused when your processor has to work hard; like when several programs running and processes in back ground. You can check and kill them with task manager (FDC soft task manager) and batteryguard. Also soft reset kills most "unwanted" processes. A good indication for high level of processor activity is when your battery level goes quickly down.
Its normal mate, on mine when i use GPS for long time it does the same, processor works hard and battery gets hot.
Not sure if navigation alone causes your battery to run hot. Since navigation can run on 200Mhz processors and Mega processor has much higher clock speed it is overspecified.
The influence of phone close to windscreen and therefor impact of light/sun may be much bigger. When I run navigation (TomTom) in winter phone stays nicely "cool".
Not sure if it could help but once i noticed the Mega too warm and discharging instead of charging, after i connected it to the notebook via usb cable!
Rebooted PC and HTC and everything luckly returned normal...

Indeed a soft reset in most cases solves this.
Yeterday I had multiple shutdowns and reboots. 1) maps. First use after update.froze,shutdown,reboot.2)Google Nav.shutdown,reboot. Great cause I was in Williamsburg and didnt know where the hell I was 3)web browsing in Skyfire reading Google reader plugged in to charger. Froze shutdown,no reboot, battery icon comes up with overheat warning. Thermometer warning triangle. Phone was warm but didnt seem burning hot. One more for good measure later. I have had a random shutdown here and there, usually after running maps after an update but never successive ones like this. Anyone have any thoughts? I'm not overclocking not using set cpu, had some freezes with it so I'm at a loss.
Vibrant vibrating nicely now,Kthx!

Sounds like the hardware is overheating to me. May want to take it to the store and get a replacement.
I am charging it using the provided USB cable and adapter, but the phone is almost too hot to touch when I wake up some mornings. It quits charging because of it, but it still remains very hot. It happens irregularly and I cannot pinpoint the problem.
I am running completely stock AT&T.
Can someone help me figure this out?
Edit: some more info: The cell radio has turned off with this issue at least twice. It turned back on after a restart. Airplane mode was not enabled, so I am not sure why this would happen. When charging at night, I run the Sleep As Android sleep tracker, and it's on my bed, but I run it every night and I am not sure why it would only give me problems occasionally (every ~10 days or so). It's possible I bump it in my sleep, but would that cause this issue? When I wake up it is fully plugged in and too hot to continue charging.

Is there any wakelocks keeping your device running? Look into it. Something could be keeping your device running in the background. Or perhaps something is turning on your device.
Worst case scenario is that you have a defective device in which I suggest you go see an att repair center or call att so they can exchange it due to defective issues. The replacement will be free.

Well put, reminds me of a scenario I had on my SG3. When I had first gotten my SG3 awhile back it would give me temperature warnings every so often (2-3) days. I found the problem to be that a couple of my applications were running background processes that were very cpu extensive and keeping my device awake. This caused the CPU to ran at nearly max frequency throughout the entire night, thus over heating my phone. I wiped every application I had and reinstalled and set background permissions to not allowed for a majority of them; this resolved the problem.
I haven't experienced this at all on my SG4, but I still disallow a lot of my apps to use background processes unless necessary. I did read online that some of the SG4 devices did have a defective heat sync though, however I'd try removing all your applications until you're down to bare minimal stock and reinstalling and keeping an eye on what could possibly be running your CPU up when your phones locked.

I'm guessing that it has a spike in temperature, it turns off the charging, but it still is plugged in so the temperature keeps going up. Hottest I saw on it was around 65 deg. Celsius.
I attached a few graphs of this happening on different occasions (one portrait is the same day as the landscape). The fast drop-off is where I unplug it and let it cool and reinsert the charging cable, and it surprisingly does not get hot again. No restart is necessary, so I doubt there is much to do with the phone's CPU but I could be wrong.
My phone is rooted with xposed installed. I've been like this for a year and half now with no issues. I am running Kernel Version 3.10.84-perf-g6898f68.
The last few months I have noticed apps being super slow. I never really connected it until now I just realized that it's mainly when my phone is plugged in.
I have installed CPU-Z just now to see what is possibly going on but the only thing is that I hardly ever have RAM.
My CPU usage goes from 8-20% when unplugged to 25-90% when plugged in and stays that way. Maybe I just need to update my build?
they are slow because u are using turbocharge that makes phone temps go higher than normal, and cpu is throttling.
As fliperpl said, that's correct. Also do not use your phone when it gets hot, especially this phone because I've read multiple times the area near the navigation bar starts getting dead if the phone/screen is pushed to higher temperatures.

Increased CPU usage during charging, assuming your hands on usage is the same when not charging, could be several things. By chance do you have anything at to run only when charging (i.e. pictures/video backup)? This could use cycles while charging.
I flashed crDroid then used TIB to restore all my data. I had to flash an old version of TIB because it would crash upon startup every time. Anyways... my phone is like brand new again. I love it!

No I didn't have those settings on. The only weird setting is that I don't auto-update apps. I want to do them when the time is right, not just whenever I'm connected to WiFi.

Yeah my phone screen started turning yellow in the top left portion of the screen. I didn't know what it was until just a couple days ago. Thanks for the heads up. I will remove my phone case when in heavy use and be careful not to overheat it any more.
Hi guys and girls,
I've got my A5 a few days back, and at start it worked great. I've messed up with a lot of software, tried everything out, and instead of uninstalling everything I thought it'd be best to do a factory reset. That's where my problems started.
While I set up the phone and installed all the apps (updated) that came with the phone, connected to a 100Mbps optical internet via AC wifi, I lost about 15% of battery. Okay, who knows what the phone needed to do, lets move on.
Next day I was just using Whatsapp, messaging with my gf, and the phone was a bit warm with 20-25% brightness (auto-off). The battery temperature was 32-33C, and I used an infrared thermometer and measured 33.5C on the back of the phone at the Samsung logo. Then I just browsed the settings, setting up my phone a bit more, and it was still getting warm, getting anywhere between 31 to 33C on the battery and around 33C with an IR thermometer. I still can't say much about battery drainage but the phone is getting pretty warm even while browsing the web or doing non-intensive tasks.
Does the A5 2017 get warm or is it just me? Should I RMA it?
Have a520f, 33C is near average. But it's also dependent on the weather. Fast charging or charging with the screen off will raise it. If it wasn't always like that, maybe something in the background is using the CPU, checking for updates or notifications. The CPU/GPU is like a car engine, running at various 'speeds' and 'weights it is carrying', and it does get warm. Only if it gets hot, then it's a problem. Many apps could do those checks once the screen is turned on. Uninstalling/changing settings will only help with battery life (percent drain), the temperature is ok. The a520f (and a510f) also has touchboost, temporarily raising the CPU clock when the screen is touched. Might be noticeable with background tasks while using a keyboard.
Thanks friend. Didn't know about "Touchboost", you opened it up for me a bit there.
While the screen is off, It's perfectly fine. Once I take it in my hands, it starts to get warm around the Samsung logo. It's probably screen + apps + nowhere to dissipate heat, but I wasn't noticing it at start. I've only had it for a couple of days now. I don't know about the battery drainage, with a charge lasting me ~40hrs with 7h SOT I wouldn't say it's draining at all - though my screen is at low brightness, 1/4 max.
Just wanted to see what you other guys are getting as I thought it was high. My ambient is around 24-25C all year long. I've seen tests where people weren't getting more than 30C at all, but as you said, it's the ambient that dictates that.
Idk if this is only with mine but sometimes I turn the phone off completely and put it to charge and it happens that it can reach like 35°C without touching it. Now the phone is plugged, I only browse with chrome facebook.. and it is like 37°c. That can happen when it is not plugged too. Using wifi seems to be better though.
I dont think I have an important battery drain because it can last about 6-8h SOT normal usage.
Onr other thing, when I turn on the mobile hotspot, the battery drains way more than usually and heats up too.
