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).

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.
it runs fine with wm but when switching to android it over heats and just shuts off im guessing with all the programs on the android its causing the phone to over heat.
any idea why it is over heating?
From what i understand it is because the android operating system is being run off the SD card, so the SD card is constantly being accessed by the phone hence the phone getting hot and high battery consumption (even when in sleep mode).

Are you overclocking your Android? Overclocking puts lots of work on your phone cpu, thus causing it to overheat and restate itself.
I'm overclocking. However, I would suggest using Set CPU to make profiles to make sure the phone stays cool. I'm underclocking when the screen is off and just under normal CPU speed while charging. When I was overclocking while charging, it would get up past one hundred degrees! (Of course, I rectified that quickly.)
This is the main reason why it took me so long to switch to android. So far, Shub 1.4d is the only build I've found that doesn't maky my poor phone overheat like mad. It still gets a bit warm unless I underclock it to about 800mhz.
funny my phone never over heats. It only gets warm when I play a game or long lenths of tethering.
So I have the rev11 nexus 4 and it seems to have pretty awful battery life.. I'm running cm10.1 with the latest faux kernel with the faux clock app all set up: min clock is 594, max set at 1.35, intellidemand governor, eco mode and snake charmer on, voltage at -50mV, as well. I can't fit hardly any apps on this phone because I mistakenly got the 8gb version and can barely fit all the pictures and videos and music.. So no rouge apps or anything effecting the battery (I've already checked). The phones battery is at 40c, and CPU temp at 56c. Because of this, even when I have my phone set up the way it is and the brightness all the way down, I still only get 3 hours MAX of on screen time before it shuts off, completely dead. I've had this phone for a month but I'm about to call for yet another replacement (first one was defective but still had really good battery life). Does anyone have similar issues and should I definitely call and try to get a replacement?

Battery drain is mostly caused by installed user apps running in the background and/or sync settings. Have you installed BetteBatteryStatts to see what consumes most energy? Also install CPU Spy for deep sleep issues.

Well as I said in my post there are no rogue background apps. The only apps I even have installed are reddit, fauxclock, cpu spy, and xda. I've looked and no internal processes use up much battery also. It's just the screen which is on the lowest brightness setting that seems to suck all the battery which usually doesn't even last three hours.

Maybe a faulty battery, i get 3,5 to 4 hours screen on time with 50% brightness. Running stock rom and kernel atm.
I haven't had any battery drainage with my N4, but with my previous phone I did. In most cases when I had that type of drain, I would reflash the radio or flash a different one and that would cure it. I'm not sure what would cause the drain, but I was flashing different roms and at some point radio performance would drop off. I have seen some complaints with severe battery drainage with the N4, but I haven't seen anyone trying a fresh radio install. Might not help, but could be worth a shot.

I think what I'm going to do is just flash it back completely to stock and just use it for a week without installing anything. If I still only get 3 hours of screen on time I will try to RMA it. There just has to be something screwed up with this phone though because my last phone with the same settings applied got at the very least 5 hours of screen on time. When I can't even go through half a day on this phone with normal usage, even after tweaking and cutting performance along with always having low brightness then I think there is a problem.
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.
