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.

High brightness = freezing

While using phone (longer) or while playing games with Brightness set to 70-80% the phone tends to overheat and freeze.
But when brightness is set to automatic (in my current enviroment its mostly low brigthnes) the whone doesnt overheat or freeze.
Is this behavior normal for HD2. IM using it for 4 days now.

Freeze on heating is an issue with the HD2. Mostly when batt-temp goes over 45 °C.
Gives a lot of fun in high summer

either send it in for repair or replace your battery. I use my phone constantly when plugged in at night and it has never frozen on me dispite 100% brightness and being in a silicone case..

Nexus 4 battery life problems and possible overheating

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.

battery drain

was wondering if anyone notices a significant battery drain with 4.4 on dalvik.rebooting with ART to see if there is a difference.

looks like ART is holding up the battery nicely so far.

I had massive drain with Google Play service keeping the phone awake 98% of the time. This is no longer happening after reboot.

one thing i've noticed with ART besides the hopeful battery improvement, is i cant play games when using ART.that sucks. bsplayer also will not open,just lock up my device.

No problems here. 5 hours screen on time... Loving it. :thumbup:

I flashed factory image of kitkat and I noticed that my phone is getting very hot while charging even when I was not using it.
So I started investigating and I noticed that the processor,which should idle at 384 mhz,is actually staying at 1 GHz(only 2 cores).
I know it can be because of mp decision but then I changed screen off time to 1 mins and still it hovers between 1 Ghz to 1.1 Ghz(only 2 cores) which in turns increases the battery temperature (around 42 degrees centigrade) and may lead to slow charging.I cleared the stats and let system monitor record fresh stats for 30 mins and result was same. I think it could be a bug or some kind of background task which gets triggered only on charging(maybe processes like trimming etc) . I was not able to identify the process as most of the wake lock detector and process monitor apps are not compatible with kitkat.
I used system monitor app to monitor all this. Anybody else facing this issue???
Thank you
NOTE: I restarted after all this and battery level was at 70% and temperature was around 43 degrees after restart everything seemed normal and temperature gradually went to 35 degrees (checked when battery was around 95%).

I experienced a hot phone with my first 4.4 flash but don't have that after reflashing. I get really quick charges. And a nice batt. Life. Still with the same problem though.... I can't play zombie tsunami in ART mode. I'll try uninstalling then reinstalling to see if it works

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.
