Running a lil hot?

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.

Overheating and battery life.

I don't know what all your experiences are, but I noticed the past few days that my epic is getting hot on the back.
I also noticed that my battery is draining more so than usual. When I got the update last week my battery life sucked, but now since this overheat thing it's gotten worse. It drops a lot even when in standby.
I do not have gps, wifi, anything else on. I am not rooted. Didn't do any battery tweaks. This is completely stock di18.
This is normal use with 3g. It's getting annoying and I'm hoping someone has an answer. Thanks!

Do you have any email accounts configured in the mail application?

This happened once or twice - I rebooted the phone and all was peachy.

Sounds like you have a rogue process wearin it out.

Yeah my phone overheated yesterday while charging....this phone has a few more steps to go before it really beats my hero...

I partly found out what the problem was, but it seems you guys are ahead of me. I had some process keeping my CPU running at 95-100% nonstop. I still haven't figured out what the process was, as now it is back to the normal 5-15%, but I'll have to keep an eye on it now.

the task manager widget turns red and it shows you what process was causing it...for me it was the xda app...a few times.

I think my problem was not backing out of WordFeud. I didn't notice anything on the task manager though. Hasn't happened since that one time.

this happens to me when i'm plugged in and using gmail. screen flickers and then shuts off. the screen-off battery indicator shows the batt. gauge and a little thermometer sign next to it indicating it's too hot.
wtf?!?! this has to be a defect. anyway, is there any official word on this? any pr from sammy/sprint?

i have read elsewhere about some epics resetting themselves a few times a day which could indicate an issue with heating (at least on a pc). so if you think it might be hardware its possible. otherwise keep doing what your doing, monitor your processes for anything thats eating it up, go to about phone > battery use > cell standby to see your time without signal. the higher this is the more battery use. also, might want to consider a startup manager to prevent the 2 DRM files (search forums) from running as this can affect batt life too
you can also use setcpu even (free on here, search it) to throttle your cpu down when it hits a certain temp.

This is very interesting... My wife and I both have this phone, she has had this happen several times after the last update (I though she was just crazy). Me on the other hand... No problem!
I need to look into this a little deeper.

The only time my epic's battery gets hot is during heavy use or gps. Gps/Nav makes it heat up like a mofo. But other than that... *knocks on wood* Its all good, no problems. As far at battery life, I am rooted and using SetCPU to turn down the processor while the screen is off, helps a ton. Not using anything other than that... was using juicedefender but then I started not getting calls or text...

One thing, I learned, that didn't help my battery was putting my phone in the locker at work. That thing must have killed my TWS and ate my battery alive.

i feel like this thread will start to die but i had a weird somewhat related issue last night. i too have had maybe 3-4 times where i woke up to my charging phone with the red LED and a screen that would not turn on, battery pull, worked fine.
however, THIS morning my phone would freeze like 30 seconds after boot EVERY time. tried a few things to no avail until I wiped, reinstalled my ROM (aosp 0.4.1) and the data from a previous backup (which was the way i got that ROM to first boot successfully according to tips in that thread).
so this worked, but i couldnt figure out why my other steps wouldnt. had to be something in the data partition of my system at the time, since changing that worked. the only thing i could think of is that app watchdog which someone mentioned to track processor usage by apps. anyone else ever experience this?

I have experienced this once when I was playing Robodefense while the phone was charging. My phone tends to get a little warm when it charges, and hot if I run something intensive while its charging. Wondering if this will be an issue when I use this phone for GPS nav while plugged into my car.

"I'm having this problem too...I didn't get any warranty for this either. Any reasons onto why this is happening...I woke up this morning and picked up my burning phone lol the temp was at 50C so I took out the battery and let it sit for 15 mins...it went down to 30C, then after not touching it for another 15..it was at 17C...very odd...what should I do, this crap is going to die within the next hour I'm worried it will fry the hard drive or something. Need help! " - I wrote this on a diff. forum a couple days ago
I dont have anything on, no wifi, gps, or any 4g (lol only if I could find it)...I even got rid of my facebook/twitter/weather updater widgets. The only thing that updates is email, and that's only if I click on it. The battery has been dying a lot faster and I charge my phone next to the window now because its like 20 degrees outside here in Chicago, so that brings down my phones temp lol....and today, my phone's battery life went from 100 to 5 percent in about three hours of barely using it...wtf?!
Also, another problem...sometimes when I lock my phone and unlock it after taking it out my pocket or something, the screen doesn't seem to respond...I keep swiping my finger over it to put in my password and it wont do anything and it only works when I slide up my phone for the horizontal view. This happens like 4 out of every 10 times I open phone.
Very embarrassing especially if your trying to get someones number down, I stopped showing off the phone now ...lol

Galaxy A5 2017 (A520F) overheating issue

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.

Anyone having issues with the High temp warning while charging?

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

Battery drains fast and is always warm even after a battery change

[TL;DR]
Phone battery suddenly drains faster than usual, drains to 0% overnight. Problem still persist even after April update and after battery change. Can't find any solutions. Help me.
Hey, so about a week ago something very strange happened to my Mi A1 and got worse overtime. So what happened was my battery went from 80+% to 0% overnight. I woke up confused and just recharged it and didn't think too much. After a full charge, I noticed the battery drains abit more than usual and had to plug it in constantly. Before going to bed I charged my phone to 100% to see if it would drain to 0% again. It did. As time passes the problem gets worst. The phone started getting warm when charging (around 40+°C up to 50°C) then after a while the phone runs warm even when not charging (never goes below 40°C). My phone always used to run at about 30-35°C even when charging. I changed the battery myself because there was no warranty on it but it didn't fix the problem. However it did help abit. The battery drains ever so slightly slower now but still drains to 0% overnight. It still runs warm but now it does go below 40°C (rarely). Before and after the battery change, the discharging rate is about 700mA and sometimes reaches 1000+mA (used an app called Ampere, not too sure how accurate it is). The phone was also warmer than usual when charging even when the phone was off (before and after the battery change). I tried factory resetting to see if that does anything but had no luck. I also tried using a Wakelock detector app to see if there was an app excessively triggering a wakelock but all seemed normal. I even tried downloading a "battery calibration app" which obviously didn't work. So I feel like it's a hardware problem.
Now here's what I did and did not do to the phone before the problem happened. What I did was I do charge the phone quite alot most of the time. What I mean by that is when it hits about 30% I'll plug it in but I never leave it plugged in after a full charge or charge it overnight and I seldom let the battery drain to below 10%. Even so, the phone never got warm like how it is now. That's about all I did to it. Now what I didn't do was, I never tried to install custom ROMs or root/modify my phone in anyway except for the post about how to enable 4G+ which didn't work for me.. My phone is completely stock. I also didn't install any new apps from the playstore or from any 3rd party sites nor were there any updates for any apps installed in my phone. I've had the same apps installed for a couple of months before this happened. I also haven't dropped my phone for a couple of months. I only dropped it less than 5 times from short heights and I have a very rugged case on. I also didn't use any 3rd party chargers. I'm still using the charging brick and cable that came with the phone. I have tried using other chargers that are 2A but no luck. So basically I didn't do anything out of the ordinary prior to this problem.
Just some extra information
1. The hottest part of the phone is at the top right corner of the back. I assume the CPU is there (?).
2. It happened before the April update. It was the same before and after the April update.
3. Phone is running on Android Pie if that wasn't clear
4. The phone is only 10 months old
5. My phone is the Global ROM version
6. Performance wise, its still responsive and snappy. Doesn't lag or freeze or anything.
6. I always have mobile data on and use it as hotspot for my laptop at uni. I have been using it like that for the past 9 months. However the problem happened when I was at home during sem break so I was mostly connected to Wi-Fi.
Sorry for such a long post. I hope somewhere out there, there is someone who can help me or other people that have a similar problem so we can fix it.
Thanks.

In the upper right corner, should be the modem area.
Try holding the phone on airplane mode during the night and monitor drain.
Also, try changing the SIM slot and do an APN reset. If this fails too, try changing your SIM card or if u can, try another operator SIM.
If you changed any value with QXDM PRO , try and put back the default values.
Good luck
