After the Android 13 update, I feel like my phone is way hotter. I decided to check Thermal Guardian and it always stays in the section and it has a lot of spikes (which means the phone get hot very often). Any ideas on how to reduce the heat?
I'm kinda scared that it'll effect the phone battery, causing it to swell.
Changing the refresh rate back to 60Hz make it cooler a bit, and I also use Thermal Guardian to lower the thermal threshold.
Install GSam Battery Monitor and after a long time, check what causes the most battery consumption.
If it's the Android System or Kernel, the problem could be services that run in a way that's hard to control, so then start e.g. by disabling unnecessary Google and Samsung Services functionality.
ze7zez advice is great, but I'll also recommend full factory reset after any major OS update, a lot of conflict and issue could be cached from the previous OS​

My only real exposure to android has been through my Samsung Galaxy S3, LG G2 and now my N7. While a lot is different, there are many things that are similar. One big question I have is around battery life and what is using my battery. The details seem very limited on my G7 with Kitkat.. Broad categories like Screen, Android OS, etc. No apps are listed though (ie Clash of Clans, etc).
My battery life has just sucked since I bought this and it seems like screen and media server are the major consumers. Not sure if game play is coming under media server or not, but no individual apps are being listed and I can't seem to change the duration that the displayed average is over (like a forced reset to check usage only from that time forward).
Is there something I am missing? Can I get the detailed info per app? What about resetting the stats so I can get a picture over a specific period of time on what is using it?
Thank you for the help.

Unfortunately getting detailed app usage would require a separate battery monitoring app, which none work with Kitkat due to changes under the hood to a service that they all relied on. A possible fix for the media server is clearing gallery data and cache and let it all reload. Sometimes i think it gets stuck and endlessly tries to load stuff ( i don't have much experience on that particular battery drain). The way to reset the battery usage time is fully charge it, that resets the stats. Sometimes just a reboot will reset them as well, but it's usually a hit and miss. If you play any heavy duty games like modern combat, real racing, gt racing, etc, those will eat up a good amount of battery when played a lot. Something else you can check is location services, they can sometimes cause unnecessary drain. I keep those off since i don't use the tablet for GPS.
Hi.
Why is G3 laggy ?
Mainly because of the heat issue it has, at least that's the case with me.
When the phone is at "normal" temperature after using internet and so on,
it gets a little warm. After that the thermat thtottling limits the max cpu freguency
to about 1200mhz. No wonder it gets laggy.
I did some testing.
I ran the Antutu about 20 times in different temperatures.
Before running Antutu, I booted the phone, closed all the apps, in airplane mode and waited 5 min before each test.
When the phone was "hot" I got scores about 32000. When warm, 37000 and when cold, in fridge, I got over 42000 every time.
The fridge also showed that full cpu speed was used, which was not the case when it was warm or hot.
So.
Some of you guys have a good cpu and motherboard, which means no lagging.
Some of us have not so good and that's why we get even reboots because of heat.
Easy fix from LG would be very strict thermal throttling for the reboot problem.
But at the same time we get even more laggy phone, because of lower cpu frequencys.
F..
I can never pick when it will heat up, but when it does the battery just drains (I'm running v10j).
I think it is a screen issue. Something to do with what the processor and screen run. I'm on 30-40% brightness almost all the time (which is a shame).
Benchmarking in the fridge... that is classic...
I'm starting to think it's the LG software on the phone causing the heat and lag, i recently had issues after removing an app (App Updates) then factory resetting after removing this app and factory reset it would break a few function in my phone including making me go through the setup process after every boot and recent apps menu not opening and notification bar somtimes not pulling down (restart sometimes fixes this) and unable to open settings from the notification bar and possibly other things BUT despite these issues my phone was VERY COLD with the screen on!! and MUCH less laggy. but after i reinstalled "App Updates" and factory reset the heat issue came back.
Just to be sure, i tried again with the same results:
I removed "App Updates" again and factory reset and the heat and lag went away again. (but some stuff breaks)
I installed "App Updates" again and factory reset and the heat and lag came back again. (but everything works again)
I'll take up your suggestion and try to freeze App Updates.
How do you freeze app update centre?
With Titanium Backup. In general I don't uninstall any app, I just freeze them. Works the same and I still can go back if something happen.
So. It's only working if we freeze the app then factory reset? After a factory reset it's staying freezed that is?
U don't really need to factory reset after freezing. Just freeze it and it will be as good as uninstalled, but, with always an option to defrost.
He factory reseted because he was facing issues.
Well, I mostly asked because there is no difference.
I'm on stock, rooted, s-off
my device is getting extremely hot during normal use.(i dont play games at all, just whatsapp, facebook, news etc..)
sync is off, auto brightness.no google location reporting and history, no google now or history.
and using bbs to see what is going on ,i have no wakelocks and looking at battery screen, screen on time and awake time are almost identical.so nothing is keeping my device awake.
but for some reason, when the device is idle, the cpu goes nuts!
i installed cpu status bar xposed module so i could monitor cpu on real time, and i see the device jumping allot from 300mhz to 960 and 1000+ for no reason.(without touching it, and no apps running).when i touch the screen it scales to maximum.
it drives me crazy because i dont understand why the cpu behave like that.there is no logical reason for cpu going to max when i'm typing text.
its unbearable, cause its getting really hot while i hold it.
i have tried various kernels(elementalx, skydragon, faux, ionx, hacker kernel, but all of them shows that behavior.
on my old i9100, i never got that behavior, ondemand governor was perfect and i could reach 4 hours of screen on time.with the m8, i can barley pass it , going for 4-5 hours, because its draing too fast.
any suggestions?
*EDIT*
tried a factory reset, and i just installed xposed with cpufreq status bar module, and the device is still going nuts.WTF?
Can I ask... are you sure this is abnormal? I mean, are you seeing ill effects? Is the device laggy? Is your screen-off battery time awful?
All OS's do stuff in the background, and "idle" doesn't really mean anything at all to be honest -- even when you "don't have any apps running" there are apps running, and you'll always see the CPU cycle from idle to low speed to high speed if you're looking for it.

i know there are background process and apps, and i don't except the device to stay at 300mhz all the time, but its quite annoying to hold on to a device and feel its temperature rising to insane levels without doing anything fancy with it.just texting.and every touch ramp the cpu to the max frequency, its weird.and unnecessary.
i don't know if its normal behavior, as i mentioned, my old i9100(galaxy s2) would not act like this. and i could get 4 hours of screen on time, and here, i get 4-5 hours max.it dose not seem logical.
I'm not using lte of nfc or BT.my reception is full(both wifi and cell).
i just want to know if this a normal behavior? anyone else having this heat buildup on light use?
I have a similar problem there on M8S. I killed half the background tasks, disabled syncing, auto backups, and then I open FBreader(or any other app) at 30% brightness and all the cpu cores go to 50 degrees C, heat up my battery to 43 degrees C. It results in loss of 40% of battery charge in just an hour. With screen off my device usually consumes 1-2% an hour. Whatever I do, I have never seen at least one core sleeping, they always work at 600-900MHz.
Dears,
I bought a G3 phone just a month ago and, apparently, the battery was lasting almost a whole day in the first two weeks, but, after that, the battery became to last less than half day. Of course I've installed some applications since then, but it's very strange because the Android doesn't report any abnormal processing load of any application, so I'm presuming the OS is causing the high battery consumption. After I bought the phone, I upgraded the OS to Lollipop almost forthwith. I'd like to know if it's a known issue of G3 with L version and there is something I can do to increase the battery life.
I've installed some applications that utilize the location services, but Android doesn't claim those applications are draining the battery. According to what Android reports, the screen and the OS are main things that are consuming more battery ( 24% for screen and 16% for OS )
Thanks in advance

You should root your LG G3, then install xposed, greenify amplify and powernap. Those apps will control your wakelocks and alarms. This will also improve your battery life.
May I also suggest to reduce screen DPI. Reduced mine from 640 to 534, added about 45-60 mins of SOT
Are you talking screen on time? Or idle battery drain. Because these are two very different things. Quite often it is the way you are using your phone and the applications installed that will cause your battery life to become worse.
Of course you have the obvious things such as disabling data when you aren't using it and wifi and so on. Through my experience I have found amplify to be of little use if you are generally cautious about the apps you install. Facebooks apps are terrible. Any instant messager will be causing some sort of drain. The problem definitely arrises from these things and while you can install many other apps to limit these things. I often find it is best to address the problem at the source. Perform a factory reset. Then begin installing your apps one by one and seeing when the hit comes. Thats my advice. Then find an alternative to the problematic app. That or BBS to find what is causing wakelocks. Remember, if you are gaming the processor is going to eat battery.
To follow up on orcam he is in the perfect rite direction as for reducing the dpi its a placebo effect you can read up on it on many threads and sot is in most case 7 to 12 min longer reduce britghness get rid of carrier iq is a big battery hog debloat the system apps like facebook and all the other bloat that lg uses is bad on battery life
The best way to get better battery:
1. Root
2. Debloat - delete useless app's and files from root directory!
3. 3845*#855# (855 its international model, put your model: 851, 852, etc) and search for Thermal Daemon Mitigation OFF, then click and enable it, and search Fast Dormancy and turn off, and in High Temperature Property OFF enable it too and turn off your phone for atleast 40 seconds, turn on and wait 1 minute with screen on to update those things.
4. Xposed with Greenify
5. TricksterMOD and set the CPU freq. to min. 300Mhz and max to 1.540MHz (if you use the phone normally, and dont play games).
6. in TricksterMOD set the GPU to 330Mhz for powersave.
7. Developer Options active the "Force GPU to 2D graphics"
8. Use brightness according with your needs, not only keep it in 100% (i know in 100% looks beautyful but screen is a battery beast).
This is what i have in mine and i can guarantee if you use moderate it can go up to 3 day's, mine got 5 hours and 20 minuts in On Screen Time so...
I am having a very frustrating issue after moving to the S22 from my S9.
In direct sunlight, the screen is nice and bright and readable.
However, after a few minutes in the sun when the phone gets warm, it is automatically dimming the screen meaningfully - to the point where its really not readable.
I have tried both with Adaptive Brightness enabled and disabled. From what I have read it seems to be something the phone does automatically when warm to preserve battery or regulate the heat.
However it makes the phone unusable in the sun on a warm day once it warms up. Has anyone figured out a way to manage/disable this?
Use in direct sunlight should be measured in seconds not minutes if at all, not recommended.
You can severely damage the phone like this if it overheats especially if the ambient air temperature is high!
More than likely the phone isn't optimized and has a lot of junk running in the background contributing to high battery consumption and excessive heat. Tone it down...
thanks for the quick reply.
the phone is very new so shouldnt be that cluttered, and its having this issue that the S9 never had. Its not even 70 degrees today (although its direct sunlight) so its not like I am at the beach.
Would definitely welcome any suggestions on how to "tone it down" though as I would like to make sure I am having it run efficiently...
It seems strange that a brand new phone with better processor, etc should be having this issue in moderate temperature compared to the older phone I had for years...
Toss any social media apps; they should never be installed or activated if preinstalled like FB.
Try temporarily disabling Google play Services; gmail needs it(use manual sync) and Playstore needs it (enable/reboot for Playstore). Paid for apps that need Playstore; activate them, then use Karma Firewall to block Playstore so they continue to work. Firewall block those apps as well if they don't require a internet connection.
Samsung and Google cloud don't help matters, disable if you don't use them. Google Backup Transport* is a prime offender.
Set brightness to manual and keep at 50% or preferably less... don't burn your eyes out.
Clear system cache, don't use SmartSwitch to transfer from old phone... it can cause issues.
Don't use any of the Device Care battery optimization options as they cause erratic behavior and even increased battery usage. Only fast charging should be toggled on if you want it.
Instead find the power hogs and deal with each on a case by case basis. Set display to medium resolution ie the optimized setting and leave it there. If you run at 60hz that will also save power.
Disable carrier, Google, Google Firebase, Samsung and app feedback. Not sure if Package Disabler works with Android 12 yet, that's an easy way to clean up bloatware and easily toggle apps on/off if needed. Stay with the stock launcher as it's efficient and powerful.
Lol, it's a long list and some depends on your own desires/usage. Once optimized block system updates as they can undo everything... be careful before doing them, wait and see if and what issues they may introduce.
Play with it and explore... it's almost impossible to crash a stock Android
Be careful what you install though, you are what you load. One poorly coded app can cost you a factory reset if you can't undo its damage. Rarely, they can alter hidden user settings and this remains even if you uninstall the app! Repairing this can be time consuming and a pain.
*since you don't have an SD card slot to use as a data drive work out a good backup plan for all critical data or you will lose it eventually. A OTG 5tb flashstick can be used for frequent "dirty" backups.
In addition use at least 2 hdds that are physically and electronically isolated from each other and the PC to redundantly backup critical data!!!
Copy/paste folders/files only, Do Not use SmartSwitch to backup any critical data!!!
Like it's predecessor Kies, it can fail you miserably. Verify folder count and data size after a backup, spot check that the data is readable.
Once lost, data can rarely be recovered... plan ahead to avoid this sad fate.
thanks this is thorough and I will examine these things.
I guess my takeaway based on your response is - there is no way to disable whatever is causing the phone to autodim when it gets warm?
because I think its related to the phone itself physically getting warm from sitting in the sun (although I understand these things can exacerbate it).
I am not having any overheating issues other than when its warm out and the phone is in the sun and it then toggles down the brightness

Auto dimming is a last ditch effort to protect the phone. The display acts as a heatsink for the mobo as well as producing a lot of heat of it's own. The sunlight has a high infrared component to it.
Thermal stress is best kept as low as possible for OLEDs. The increased temperature causes expansion of the components; that could cause a failure by itself. The OLEDs are made of extremely thin layers (microns thick) so they could potentially overheat unpredictable fast as there's very little mass to them.
Best not to tickle the dragon's tail...
Hi there, just got hands on a S22 myself and observing this dimming issue. Obviously it's all about apps using GPS. I notice that the screen goes dim to about 40% max brightness when I'm in Google Maps or Locus Map. And this doesn't matter if Adaptive Brightness is on or off. Going back to any other app, the screen comes back to max brightness.
That's a no go as I'd buy the phone for my outdoor experience with Locus Map.
