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.

two weird issues?

The two weird issuse I'm having are when I touch the screen in the center a little more than half way up iget a circle ripple kinda like when you push on a laptops LCD screen. The second issue is when I use my camera or place a game even with full battery the phone shuts of after five min? The rom that I am useing is the latest typhoon rom this has been going on for like three weeks both issues started around the same time. Any help or suggestions are greatly appreciated. Thanks Kevin

The 5min shutoff sounds like its overheating... or the batteries going bad
As for the Screen Ripple.. I'm not sure... If you still have warranty consider restoring it to factory default and sending it in for a replacement.

the screen issue is weird indeed.
if you have SetCPU installed, make it notify you if the phone gets hotter, somewhere between 40-41 degrees celsius is fine, you can make it underclock the CPU to somewhere between 500-800 MHz so it would cool down, and you won't get that issue if it's an overheating problem. if it keeps turning off then I agree with the post above, it might be your battery.

yep overheated , screen ripple is caused from overheating.
Had a friends like that but luckily had a spare mainboard & he just got a screen assembly..
He too was on android but has decided to go with WM6.5.5 & see if device lasts longer on this OS.

Anyone running Android Auto ?

Hi,
I'm experiencing some problems when using Android Auto. I think that my device is overheating.
Maps becomes very slow after about 30 minutes driving. Sometimes the phone is going very hot and is unresponsive during few minutes. I checked the cpu temp after a drive today and got values close to 60c. I'm running LOS 14.1 right now. I was using CM 13 previously and the heating issue wasn't so huge.
So I wonder if anyone else is running Android Auto successfully on this device ?
update : I disabled thermal throttling using Kernel Aduitor. Android Auto is running perfectly fine now. Phone is heating a lot (80c for CPU but 25c for battery) What is the thermal throttling ? Is it a kernel feature ? Is it the same as thermald ? Is it tunable ?

I would be careful with turning that off. Thermal throttling basically checks how hot your phone's internal components get, and when they reach a dangerous level it forces the device to slow down.
Turning it off means that your device WILL work at hotter temps, but you risk damaging the CPU, screen, battery, etc.
The reason the phone was getting slow is due to 1. the screen being on all the time, 2. the GPS constantly updating.
The N4 wasnt meant for such tasks, so it overheats.
One solution: get a mount that sits on top of the airvents, so that cool air blows over it.

Well the screen is off with Android Auto. But of course the GPS is working. The battery temp stays low at about 25c. The screen is not hot. Only the back of the phone (the upper part close the camera) is getting hot. Thermald is still active and there is still a protection against battery overheating.
I really think that the Lineage kernel is too much aggressive regarding thermal throttling. I tried other kernels but unfortunately they slow down clocks too much when the screen goes off.

Yep, I have the same issue. I was originally using slickrom stable release, then switched to weeklies and the issue showed up. Slickroms is based on lineage, so switched to lineageos and I've been seeing the same problem. Haven't found a solution to this problem (using Android auto with nexus 4 and lineageos).

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.

heat issues

Is anyone experiencing heat issues? My phone gets warm to the touch from light web surfing and twitter use. Yesterday my phone overheated when taking pictures and went into some weird safety mode and disabled some features until it cooled down.

Already a thread for this....
