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.
Hey guys,
I currently have a Galaxy Nexus and I really love it, but I'm one of those guys that really loves to try new devices and I feel like the Note would be the last device I wanted for a very long time if I got it. I thought the Nexus would be this device, but the Note just intrigues me..
I was just wondering what kind of battery life you guys see? Isn't the Note battery over 2,000 mAH stock? (2,600?)
I guess the huge deal with the Nexus for me was ICS. I've been lurking your development forums and saw that CM9 is pretty much close to functional aside from the camera and some other things kernel related, is this an incorrect assumption?
Lastly.. Is ANYONE using this on T-mobile? Either living with EDGE speeds or even having a mobile hotspot on the side to use for the data?
Thanks guys!
Also, is there CM7 in any form?
Hi there!
For battery life its very dependent on the user, the note comes with 2500mAH of battery power, I find it lacking because of the new stuff I can do with the note as compared to my Galaxy S1 and S2.
For Cyanogen

As EarlZ said battery life would depend on usage pattern.
With my usage pattern, averaging about 2.5 hours of screen on time, at the end of the day, after about 15 hours, the battery is at about 40-50%. I use it mostly for browsing, & watching videos. So I still charge nightly but I find it more than adequate.
My auto-brightness is set to on and I don't use any additional power saving features.
As other posters said, the battery is 2500 mAh. As for battery usage example: today, after 13 hours of usage, the battery still has 38% remaining.
Usage means: data connection active all the time; display on for 2 hours (auto brightness); Nemo Picross played for about 1/2 hour; browsing, email, a few SMS, a little talk (just a little, some minutes); bluetooth on all the time and a MBW-150 connected using OpenWatch for at least 10 hours; WiFi on for about 1/2 hour in the morning. Also, I don't use any battery optimizers, no task killers etc. It's basically a stock Galaxy Note, with Zeam Launcher instead of TW, and rooted.
As for the battery - previous posters are spot on. To sum it up - most likely you will need to charge every day, unless you don't use your phone much (which is highly unlikely if you have such an awesome device).
As for CM7 - I haven't seen any CM7 mods for note. Maybe I've missed it, but I guess it's because ICS will come out soon for Note and there's not really a point in getting CM7 working if CM9 is so close.
As for CM9 and ICS - I wanted to wait for a more polished version and visited the forums multiple times a day, hoping an ICS leak from samsung had come out, but in the end I couldn't wait more and installed the current CM9 build (link a few posts up) and I am now using it daily (for about 4 days now). Apart from a few annoyances, it is absolutely great! Camera doesn't work yet, which is a shame, but I can live with that for now. As I get it, Bluetooth is unstable (I don't use BT so I don't care), battery stats don't work (it still shows the percentage and the graph, but doesn't give a breakdown of the percentage each app consumes). MTP doesn't work, so you have to either use adb to push files or reboot in recovery and activate mass storage there. A bit annoying, but not a deal-breaker for me, since I have a SMB file server at home, so I just put my needed files there and then pull them using wifi with a file manager that supports SMB.
There are a few more slight annoyances, for example:
After the phone goes into deep sleep, you can usually only wake it by pressing power button (as opposed to current gingerbread ROMs, where you can also use the physical HOME button). Some people report rarely not being able to wake the device after it goes into deep sleep, speculating that it might be caused by not locking the screen manually but allowing it to lock via inactivity time-out. Also, some apps show some black artifacts, as if the screen was "rotting away" before your eyes . This can be fixed by forcing graphics acceleration in the settings. Supposedly this can break other apps, but I haven't yet run into one that wouldn't work. Once my battery drained on this ROM about 40% overnight, but that was probably some bad app, since it only happened once. Also, once the screen time-out set itself to "no time-out" so my screen was on multiple hours and drained most of my battery, but this has also only happened once. There are also some random FCs and sometimes the back button closes the app, but you can just run the app again and usually it will be where you left it, so no big deal.
Other than that, it's AMAZING! Very smooth, battery life seems quite good, GPS gets a lock VERY fast (people are saying it's also true in gingerbread, but I was never able to get as fast GPS lock on any non-ICS ROM. All the apps I have tried work fine, with one exception being the CM Music app (the one for ICS). Besides, as soon as an ICS leak from Samsung comes out, I think the CM9 ROM will be in a very stable state very quickly.
So, I would say, go for the Note!
Unplugged it at 8am many phone calls with moderate usage,from 2.30pm continuous non stop web surfing and browser youtubing until exactly 6pm, 31% was left.with brightness auto wifi and gps on.
After updating from Lollipop to Marshmallow (stock UK firmware), battery life was absolutely terrible. With most of Google and Samsung apps disabled along with wifi, GPS, bluetooth and just light usage (1 hour of browsing and whats app, 30 mins calls), the phone would barely last 10 hours. Taking it off full charge at 8am and by 5pm it'd be around 20%. Whilst using the phone, I'd lose 1% every four minutes.
I tried a factory reset, wipe cache partition and everything else you can think of. GSam Battery Monitor Pro showed nothing was killing the battery and there were no rogue apps. The same SIM in my S4 mini running KitKat with the same usage easily manages a day and often far more.
I was going to flash down to KitKat and if this didn't work, sell the phone, I was that sick and tired of it.
Then I tried disabling 4G and leaving it on 3G only.
Bingo!
Battery life MASSIVELY increased. With the same usage, I'm now easily able to manage 2 days. My S4 Mini doesn't have this problem so I can only assume the problem is with the radio part of the Marshmallow firmware. I live in an area with poor reception but all my other phones on the same network have the same weak signal and none of those have battery drain.
Onto the lag then. Since upgrading to Marshmallow, the whole phone felt sluggish. Scrolling was jerky, the lock screen would take a few moments to show and even the smart manager always said I had less than 300MB free of RAM. About a week after upgrading though the phone suddenly restarted itself and upon boot said "Android is Starting - Optimizing App x of xxx". Once this had finished, the whole phone was snappy again and RAM was back up to over 800MB being available.
Bit concerned why the phone restarted itself but happy with the much improved battery life and performance so far. Will give it another week before deciding if a downgrade to KitKat is still necessary or might just sell the phone.
So if you have an S5 Mini with serious battery drain, try disabling 4G.
Well thanks for that, I was skeptical but I gave it a try. I booted in recovery mode, wiped dalvik cache and once optimization is done after reboot the phone was quite snappy. I've not tested battery life on 3G only mode yet.
According to Samsung Galaxy S5 Manual- guideusermanual.com/product-name-galaxy-s5-manual&po=356337&lang=English following guidelines are suggested by experts to fix battery drain:
Stop unnecessary apps.
Replace your old battery with a new one.
Your charger does not work.
'Android system' using too much battery.
Google Play Services battery drain.
Switch off auto-brightness.
Shorten your screen timeout.
Watch out for widgets and background apps.
Well thats unexpected
Coming here after I just got my new s5 and I gotta say this works like a charm. I disabled the 4g and I'm getting huge improvements. IAM on factory's Tom ty for this.
Just disabled 4G and I think it makes an impact, a good one. S5 G900F here.
I have S5 G900F with official stock Rom along with Marshmallow 6.0.1 update and IT DRIVES ME CRAZY!
The phone is usually EXTREMELY slow and sluggish. I cannot smoothly navigate and scroll around the apps, and I can NOT wake the phone up from lock screen instantly. Even waking up from lock screen takes ages. It is very laggy. I tried everthing and not working.
I beleive either Marshmallow kernel has a nasty Cpu bug or Samsung intentionally slows down the phobe just like Apple does.
I hate it.
What are your thoughts?
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).
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.
