[Q] Android OS (kernel) Eating up Phone resources? - Nexus One Q&A, Help & Troubleshooting

Hello,
Below is the message i wrote on the google support forum, but i havnt gotten a single reply yet, so i turn to you guys, in hope that you're able to help me
I have been experiencing this issue on and off for the past month or two. The issue being, that something called "Android OS", in the battery usage list, is eating up all my battery.
An example is, currently my phone has been unplugged for 1h30m(im down to 69% battery life remaining after i unplugged it at fully charged 100%) where the battery usage is ranked as follows:
Android OS: 72%
Display:18%
Wi-Fi: 2%
Cell standby 2%
Android System 2%
and so on and so forth.
The reason why i wrote (kernel) in the title of this question, is, that with the app "Powertutor" i have been shown that the main "app" or proccess eating up my battery, when this "Android OS" is eating up my battery as shown in the Battery Usage list, is the Kernel. Right now is shows the kernel is using 84,3% of the energy usage, Handscent has been using 3.1% and so on.
Often a reboot will bring the phone back to normal and the Android OS issue goes away for a while. A friend of mine, however, who has the exact same phone as I, has this issue, almost all the time, and a mere reboot doesnt seem to do the trick for him. His phone only lasts 6-7 hours tops, where it most of the time is just idle, and he isnt using the phone at all. While mine, when the Android OS issue isnt present, last up to 20 hours on a single charge, when i dont use it much.
When the Android OS process is eating up all the power, the phone grows really hot as well, and the difference is easilly felt. So when i feel that my phone is hot like that, i automaticly think "oh, time for a reboot".
I've been unable to find any info regarding this issue on the internet, and therefore I'm unsure what to do to fix it for real. Tried several factory setting resets on my friends phone, tried not installing many new apps, formatting the SD card, formatting the phone from bootloader (still testing his phone to see if this worked properly)things like that, but always, the issue returned, as on my phone where it only pops up once every other day.
Hopefully, someone will be able to help, or shred some light on the case.
Thank you,
Chris

Having Exchange sync on, by any chance? Try turning it off for a day, see if it helps.

"Exchange sync" being exactly what? The basic sync function on the phone that can be enables and disabled? The basic sync with your google account?
If thats the case, then yea im having that on all the time, so that it may sync whenever it wants to. The sync icon doesnt appear that often though, so cant see how this could be the reason why. But if you come back to me and tell me that this is what you meant, i will definetly give it a try
Thx for responding

No, Exchange sync means - MS Exchange account (in addition to your default Google account) that syncs calendar/email/both with Exchange server.

I'm guessing again that that is something extra you must install / set up, which i have not done. The only two accounts i have that can sync are my facebook and my default google account. I never sync the facebook one though.
Edit:
Update:
Reinstalled Watchdog Lite today, since my phone has been exceptionally sluggish, and SeePU graph keeps showing a full graph on cpu usage. I've had to reboot it twice today, in hopes of it returning to normal state. It does for a while, but then returns to a slow state where Android OS uses like 80% of the battery.
I made Watchdog Lite monitor the base android processes as well, and right now it keeps warning me that the "Base System", "Linux Process" uses up 89,6% of the CPU and 10,3MB of RAM, while nr 2 on the list is Android System, Foreground, with 3,8% and 27 MB.
I feel like the state of my phone is worsening, and I'll prolly do a full factory reset(again)/format of everything within a few days if i cant find the root of the issue this time around.
Please help I love my phone and i want it to be healthy again.

"OS" is an abbreviation for "Operating System". That means ALL of the background stuff that eats battery and CPU time that isn't attributable to a process or function easily understood by the typical user. This includes, yes, the Linux kernel, but also all the other background things that your phone does in order to continue functioning in a normal synchronized state...
Your phone has a CPU. The kernel has a process scheduler, which swaps different programs in and out of the CPU in order to make it look like it is running more than one thing at a time. Each clock cycle consumes some amount of the power from the battery, so if it assigns 10 cycles to process A, 10 cycles to process B, and then waits for 20 cycles for I/O synchronization, then HALF of the power consumed in those last 40 cycles (attributable to CPU) will be "Android OS". Clear?

Alright, I was wondering exactly what it meant when it just said Android OS, just that seemed like quite a broad description.
But what your saying is that it may be other applications that is actually eating up the power, just the kernel assigning the power to the program, and therefore the Battery Usage shows the kernel/Android OS as the culprit?
If its the case that its an app then, that through the kernel is triggering the usage that drains my phone, then how come my friend had this issues with an almost "naked" phone? He had installed just a few apps and still ran into this issue.
Am i understanding what you're telling me correctly?

It's not normal, something is causing it. Most likely some poorly written app or some other weird thing is causing the "Android OS" (which I assume is likely the virtual machine itself) to do bad things.

Today the linux process "init" has been hogging up all my phones resources, as in 77%+ of all the CPU usage :/
Was wondering if rooting my phone and installing/ flashing some custom rom would solve the issue for sure? Or should I send the phone back to the states for at checkup or repair? (dont think this is needed but now I ask anyway)
Is there an app that could track down exactly what is sucking my phone dry? Cus all that I've found are those broad references or processes :/

There is no solution, because you can't track the app that is causing the system to hang.
You can uninstall all the latest installed/updated apps and install them one by one, using Titanium - and that'll pinpoint the offender.

Weird CPU loads and system lag in 2.2 FroYo

I have been seeing odd periods of heavy cpu use and I am unable to pinpoint the reasons. systempanel is not showing any out of control apps, but sometimes shows prolonged heavy use of the cpu; often at 100% use. (also everytime I charge the device history shows 100% use the whole time, I do have dock mode active though) Often times when I see 100% load, the history shows it starting when I open systempanel, but systempanel is not showing heavy use according to its personal history chart. I contacted the dev and he is looking into it, but does not believe it is the app. The system my lag at these times, but does not become unresponsive. After a fresh reboot, systempanel seems to show normal cpu loads even when active and in the foreground, but after a time it shows 100% every time I open it. (and history shows the high use starts when I open the app, but sometimes the chart does show moderate heavy use around 50% before systempanel is even started, so I can not be sure if systempanel is the cause)
I have also been having odd slow downs and lag that a kill all command from a task manager will not fix, but a reboot does. (I am thinking this lag corresponds to random high cpu use, but because of the above unreliability of systempanel I can not know.
It seems to happen over time, like a memory leak but with cpu and system load.
Anyone else having this problem in FroYo?
Systempanel is the only app that I know of that has that level of detail about what is going on in the phone, so I can not check it against another app.
OK i was just curious and downloaded systempanel and looked at the cpu usage. First i have a uptime of 88 hours exactly. the cpu usage is between 277Mhz and 450Mhz. I'm also using Froyo and everythinds is stock (kernel, Rom).
SO maybe there is a app that isn't showing his cpu usage? i don't use any taskiller so i don't kill anything.
I have a task killer to kill any apps that go haywire. I found another app to check against systempanell it does not have logging but I can check current stats.
Guess I'm the only one?
Ok since installing a second active monitoring app, the weird cpu loads are gone; things seem normal. Both apps seem to show the same results. Though I still feel that the cpu load being at 100% the entire time the phone sits on the charger is unnecessary.

Yes, just today my gtalk froze with 100% cpu when switching to it. Had to force power off after waiting about 3 mins (power+vol down+trackball)
I am having the EXACT same problem, I was actually browsing through here to see if anyone else was getting it as well before i started my own thread...
it started yesterday actually and I am wondering if it is the new .0.4.2 launcher pro beta because i just put that on yesterday and i had no problems with .4.1
that is my speculation, can anyone confirm?
its probably not your launcher, I'm on ADW. Will try Launcher2 and see if it is better...

Finding the root cause of battery drain...

There are a number of standard steps to run through to find the root cause of battery problems, assuming the drain is caused by the OS or apps and not actually due to a physically failing battery.
I have been tracking a few battery issues myself recently and this is what I have learned from doing some reading on XDA:
There are two free apps on the app market that are typically used to diagnose battery problems:
Better Battery Stats
CPU Spy
I would recommend installing both apps. The third place to look is in the battery details in the system settings...sorry I can't remember what they look like on Gingerbread because upgraded to Jelly Bean a couple months ago, though I do remember there was less information in the stock battery info on Gingerbread.
IF you are not, indeed dealing with a physically dead battery, then the root of your battery drain is most likely caused by a background process or app that is keeping the processor in a partially active state even though the screen is turned off and one would assume the phone should not be using any power.
Android OS will automatically change the running speed of the processor in the phone based on the demand of the system. If only a few background tasks are running and updating information the speed might be 200 or 400 Mhz. If the system is running full out servicing a graphic intensive game the processor will likely be running at the full 1000 MHz speed. The speed of the processor will directly effect the battery drain.
The expectation is that when we turn the display off (not power down, just put the phone to sleep) the processor should need fewer resources and slow down, tending towards a state known as "Deep Sleep". At this point the processor us using very minimal amounts of power. Any app or process that is active in the background will prevent the processor from getting to Deep Sleep. The CPU spy app will allow you to check how much time the phone runs at various speeds. Once you install it and run it, then reset the timers in the menu and turn your screen off for about 10 or 15 minutes. Then 'refresh' the timers. Normally, you should see most of the time accumulated in Deep Sleep. There are standard background tasks such as syncing with the cell tower, updating time, mail, checking alarms etc. That will engage the processor momentarily but they should be relatively short compared to the deep sleep time. In my case, an errand process was keeping my phone at 100Mhz constantly preventing deep sleep.
Once you know that something is keeping the phone awake in the background, you can use Better Battery Stats to narrow down which process or app it is the cause. This app allows you to track the individual processes that are consuming the most time and preventing 'wakelocks'. Wakelocks are essentially an app preventing the sleep state and are very well explained in this post: http://forum.xda-developers.com/showthread.php?t=1827676
The battery info in the system settings can also be used to give clues though again, I can't remember how much detail was included in Gingerbread..
If your problem only started happening recently, then it could be a new app that you installed recently, a feature or setting you changed recently or possibly a recent update to an app that was already installed. Try to think back at any recent events that could have triggered a change in the system.
Common problem apps I have read about are:
- Facebook - seems to be bad at using lots of background processor time. (Don't run this app but reading several posts shows its a processor hog)
- Google Apps that sync - Gmail, Chrome (syncs browser history, tabs etc.), Google location stats.
The wakelocks link goes into a great deal of detail and is hugely valuable in nailing your issue down.
Good Luck, let use know via a post if you find the root cause...
Sorry, maybe I wasn't clear about it being 'dead'.
The battery is 100% or thereabouts, no problems ever with the battery.
The phone looked as though it was turned off, but wouldn't turn on again with the power button.
I have to take the battery out and put it back again, then it starts on the button.
I've cleaned the contacts, and it still happened.

To me, it sounds more like a rogue process messing up power managing or response, but it's hard to tell what it could actually be.
For instance, you might come a cross a game that leaves your phone locked in max cpu frequency, draining the battery without explanation.
If it was me, I'd re-flash the rom from Odin, perhaps with an sd card wipe too.

Wakelocks

Anyone using battery monitoring apps like BBS or GSam, can you share some of your stats here? I'm trying to figure out whether the seemingly massive amount of wakelocks I'm having is normal or not. The biggest problems seem to be coming from the kernel itself. BBS shows a lot of kernel wakelock time, and GSam consistently lists the kernel as the highest drain in its app sucker screen. Also, the Phone app seems to be waking the device a lot since upgrading to .5.51, which wasn't a problem on .3.374.
I've attached some screenshots that illustrate the problem. I'm already using ForceDoze and Greenify, which have been enabled via ADB, and I've restricted background activity and data for the vast majority of my apps. I'm really hoping there's something I can do about this given that it's impossible to use another kernel (LB and none available for this phone anyway). I've software repaired/clean flashed 3 times.
My battery drain is actually not bad at under 4%/hr (combined screen on/off) and about 1%/hour with the screen off overnight. Today I've logged over 4.5 hours SOT in a period of 17 hours and am sitting pretty at 36%. That's better than any phone I've ever used. But I worry that all the wakelocks are using my phone's CPU, raising its temperature, and might contribute to faster battery degradation.
Also, this is with bluetooth off and my Pebble not paired, but battery drain becomes substantially worse with that setup. My idle drain triples with my Pebble connected. I'm trying to troubleshoot one issue at a time and want to nail these wakelocks before moving onto the bluetooth issues.
If your battery stats looked like mine and especially if you figured out how to fix it, please share!
Given that Sony ended .5.51 deployment prematurely and is currently rolling out .8.49, I think you should update to .8.49 (or wait until your region gets the update if you don't have it yet) then recheck if your problem still persists.
Pouring time and resources into a version that Sony is no longer pushing isn't that great of an investment, especially since it's possible that it was fixed in .8.49.

Everything except the phone app using more battery was the same on .374. And I fixed that after force stopping the phone app and rebooting. I've been trying to troubleshoot this for weeks but just upgraded to .5.51 a couple of days ago. I will flash it when it comes out for Customized UK, but I don't think .5.51 is the root of the problem.
(Oh cool, Xperifirm actually shows .8.49 available for Customized UK now. Time for some flashing!)
Edit: I'm seeing the same degree of wakelocks so far on .8.49.
Update: The battery drain from "phone" is actually Android System. There's a bug in Oreo where sometimes Android System is showing as Phone/RCS in the battery stats. Doesn't explain why Android System is using so much battery though.

So I managed to get a lot of my battery drain figured out, but a few things are still bothering me.
1) Google Play Services and Android System and/or Phone (see my last post) are using the Significant Motion Sensor to wake my device constantly.
2) Sony's smart charger (com.sonymobile.smartcharger) is waking my device. I'm assuming this has something to do with Battery Care, which I find to be a useful feature. But why does it need to continue sending alarms to wake up our phones when not plugged in?
I've attached 2 screenshots from Better Battery Stats showing the first issue (Sensors/Play Services and Phone) and 1 showing the second (Alarms/Smart Charger). Note the "wakeup=true" and long times recorded for Significant Motion. This held true when I had my phone sitting face-down on a table for 6+ hours to do battery testing earlier.
Anyone else who uses battery monitoring apps: have you noticed any similar issues?

I'm with you on RCSService being main culpirt for me. No I don't think it's a bug, it actually does use lots of battery. I listen to 3+ hours of bluetooth music a day and when I saw that RCSService was using more power than my bluetooth, then I thought it was time to experiment. So I uninstalled Carrier Service and RCSService and suddenly my battery life jumped by 20%. There was something in the November update to these services that made them go nuts. Several people have noticed a jump in battery usage, but most people, myself included, thought it was down to the new firmware. Uninstalling these 'features' has made no difference to SMS for me, other than I don't get a read confirmation.
I don't know about smart charger, sorry.
Pretty sure the proximity sensor is always on and that must use some power, but I don't know what that would be called in BBS.

Thanks! I should clarify that when I say it's a bug, I believe something is using a lot of battery, but I don't know that it's necessarily Phone/RCS, because it shows up randomly as either that or just Android System. I think it might be something within Android System but being labeled as Phone or RCS. (Edit: Or the other way around; it could be 100% RCS and sometimes shows up as Android System because the phone is part of that umbrella.) I could be wrong but based my judgment on the links I posted above.
That being said, I disabled Carrier Services on your recommendation in the other thread because my carrier doesn't support VoLTE, VoWiFi, or RCS, I've never seen a "delivered" message, and I don't even use the Google Messages app anyway (I use Texra for SMS and keep Messages disabled). So like you, I don't need these services. And I do think there's been an improvement. Might be time to go through the rest of what you recommended via ADB. The only thing that concerns me about doing that is that I'll have to factory reset if I ever switch carriers and want those services, but I guess that's a small price to pay and an unlikely scenario anyway.
The smart charger thing is just weird. It shouldn't need to constantly check whether I'm charging since it kicks in when you plug in. Yesterday I disabled battery care during the day and re-enabled it at night to charge, and I had the best battery life since I've owned the phone: 4.5 hours of SOT over 18 hours off the charger with 30% remaining. I may have to look at idle drain with battery care disabled. I like the idea of battery care, but if it's draining my battery then it just defeats the purpose.
Regarding sensors, BBS has its own category for proximity sensor; this is a separate sensor for significant motion. Somehow Google Play Services and either Phone/RCS or Android System are using that particular sensor all the time. And not just listening to it, but causing lots of wakeups and doing so while the device is sitting on a table all night. I can only deduce that it's somehow seeing motion when there isn't any.

Do you have 'On Body Detection' enabled in smart lock? That would force the phone to affirm if it's moving/stationary regularly and quite often.

I never enabled that from the start, but just checked in case Google did something, and it's still off.
I also checked my app permissions, and the only ones with access to body sensors are Google Play Services and Tasker. None of my active Tasker profiles require the significant motion sensor. One of them does use the orientation sensor to turn the speakerphone on when it's face-up during a call, but I tried disabling that profile and the stats didn't change.
Maybe I have a messed-up accelerometer...do you know of a way to test that? (Edit: Found it in the Support app - my accelerometer, gyroscope, and proximity sensor are fine)
I think I might head to the Sony Mobile forums with the smart charger issue for that matter. It may be a bug that affects all phones with Qnovo features, or maybe they could at least give me an explanation.

Correct me if I'm wrong, but couldn't you just "reinstall" those services via the same adb commands? Where you typed uninstall, just replace with install?
Maybe, but I don't know where I would be installing them from...? Since I don't have a backup of the package. I uninstalled a bunch of stuff via adb before and it didn't return with a dirty reflash. I had to flash userdata. So that's all I'm going by.
I'm not sure of the actual technical mechanics, but I believe uninstalling system apps doesn't actually remove the package from the system image, so you can reinstall them at any time.
I think it's like taking down a sign on a store, the actual store is still there, just all references to it are no longer there, so to the OS it's not listed - "uninstalled".

I gave up. I still have a ton of wakelocks. GSAM shows a bunch of them even when my phone is supposedly dozing. My battery life is OK, not nearly as great as I hoped I'd have with this phone, but it gets me through the day so I've just been living with it. I have noticed better battery on the latest firmware (July patch) than June. I also got rid of the RCS stuff, which helped a bit. And finally I traced a lot of my drain to an app I was using called "hide running in background notification" which the last few firmwares can do natively.
(Edit: Sorry for missing your previous post!)
Edit: I was sadly mistaken about better battery on the July patch. The battery is only better if I'm not on wifi. I posted in the wifi drain thread about it just now.

Overheating

I bought my first Samsung phone in over 10 years, the Samsung S20 FE 4G with the Snapdragon chipset.
To my surprise the device is heating up very quickly while in use:
With light use, like messaging apps the CPU stays around 37 to 49°C,
While gaming it stays around 47 to 50°C+ (I believe the 60°C was the biggest temperature spike).
I've heard people saying that transferring data from your older phone via Smart Switch may cause this heating issue, but I don't think that should be a issue.
Lastly, I have no clue on how weather affects the phone's temperature.
Despite being winter, we're having temperatures around 40°C where I live, but even when the night comes and the temperature drops to around 20°C (right now it's 26°C and the CPU temperature is around 40°C, while I'm listening to music via Bluetooth and (re)writing this post) my phone still heats up (just not as much as in the rest of the day).
I think it's worth mentioning that the CPU temperature is also changing quickly, I don't know if that's normal or not but for instance, when I switch from one app to another, if the app I'm using to measure the device temperature (CPU Monitor) is to be believed, the temperature jumps some 2 to 5°C. It usually comes back down again, but I really don't know if that's normal.
I went to the Samsung store today, they checked, did some tests, and said that the temperature was at normal range, but they said that the temperature while switching between apps was a little strange.
They also said that their system detected a temperature spike caused by Fine Lock on the day that I bought the phone, which I find weird since it's only a launcher to the Good Lock apps, but nevertheless they advised me to uninstall it and keep monitoring the temperature for a few more days, and that if the device gets too hot (over 60°C), that I should go back again and ask for a replacement.
Anyway, should I give some time, should I worry about it, should I take it back to the store?
I have the same model as you and I haven't experienced any of the symptoms you are talking about. If I were you I'd return it and get another one. At least then you can be sure if it is normal or a defective device.
SmartSwitch isn't that smart especially between different OS's/devices.
I think you better start from the beginning...
Backup your contacts etc to the PC using cut/copy plus at least one other hdd.
Factory reset. Reload from scratch. Run factory loaded versions; do not update any at first.
Avoid enabling any power management at least at first.
See what you got and go from there.
It's likely not hardware at all but a bad configuration. Common with Samsungs and correctable.

Thank you. I'm thinking about doing it. I've talked to some S20 FE owners who live in my country (which is a very hot country) and they said that the device temperatures are basically the same as theirs, but at the same time I'm still worried about it's long term effects since I plan to keep this phone for at least two years.

Thank you, I did what you told me (except for flashing the factory stock ROM since I couldn't find it), I've only restored the apps using the Google backup, but didn't restore my settings. I've also did a mild debloat of the phone (removed Bixby and the Facebook apps) and while using the phone to browse through social media doesn't heat the phone as much as it used to, it still heats up more or less the same during gaming, so I'm guessing that might be normal.
Depending on how CPU cycle intensive the game is, it could normally use a fair amount of power.
Running background apps can make it noticeable worse though.
Try temporarily disabling Google play Services and see if that helps.

It's Honking Impact 3rd, it's not intensive like PUBG or something like that, but can be intensive depending on the game mode. It runs at 53°C max. I found out that one of the apps that I was using to measure the temperature apparently only shows the temperature of the hottest CPU core, that's why the temperature sometimes shoot up to 60°C whenever I took a screenshot for example, and then came back down to around 50°C.
But I'll try disabling Play Services and playing again.
Do you know if those temperatures are safe btw? Around 50°C while I'm gaming.
The battery's temperature doesn't go past 40°C, in fact I don't even think I've ever seen it getting to 40°C.
Anyway, thank you very much.
You're welcome. The Farenheit is scaled better for real world use.
140F is well within tolerance for the CPU/mobo as long as the battery doesn't get hotter than that. I don't let my battery go beyond 103F.
The CPU/mobo can handle up to probably 165F but it's best never to push it that hot as auto thermal shutdown doesn't always work in time to save the components that are running hot and have a sudden additional power usage spike.
Really the phone shouldn't feel hot... it's killing the battery too. Track them down.
If it feels warm when using the browser, something(s) are running in the background driving it up.
Any cloud apps, including Google backup Transport, Framework and Google Firebase.
Ditch any trashware apps like WhatsApp, Twitter, Instagram etc.
I'm using my 10+ in a case at a 75F ambient air temp browsing with a CPU temp of 89F right now. It is stock but heavily optimized.

The phone doesn't feel hot, unless I'm playing a game, depending on the game it gets somewhat hot.
It's been colder in my city these past two days, but tomorrow we'll have a temperature that's closer to normal. If the phone manages to stay in an acceptable temperature range I'll keep it, if not, I'll return it to the store and see what I can get done.
My old phone didn't have a plastic back, so feeling the phone warm is a new thing for me.
Most Google apps are disabled, I only use WhatsApp to talk to my family, I have Instagram installed but I don't even remember when it was the last time I've used it (I put it on deep sleep also).
Thank you very much once again.
Using power management can cause erratic behavior and sometimes increased power usage especially if set globally.
Developer options>standby apps, all buckets should show as active otherwise power management is running.

With Power Management you mean the Background Usage Limits from the Device Care app?

Yeap. I have a 10+ running on Pie.
Your may get different results but it's a known source of instability and trouble.
This is how mine is configured.

I did it but now all my apps under Standby Apps are set as "Active" and I can't change it. Won't this consume more battery?

Once you do that you need to track down the trouble makers and deal with each on a case by case basis. Sometimes simply cleaning the system memory in Device Care can work wonders. Keep open apps to a minimum.
Here's the old version of Device Care. It uses 360° which cleans very well but is CCP junk.
To safely use it use Karma Firewall* to block its internet access. It will still run normally.
Before uninstalling your current version use Apk Export** to make a installable copy, just in case.
*freeware, uses almost no battery
**freeware that is very useful to backup all your apps and updates for future use... ditch Playstore for reloads

Thanks. But I can't uninstall the current Device Care app. Is it safe to do it via adb?

This is normal. Just because their bucket state is marked as active doesn't mean they are running. It simple means Android is no longer managing them by assigning a bucket state to them and so on. Google it... it sounds like a great idea but it never worked well for me in practice. Android still manages the apps with it off less the added resource burden of this system.

Sorry. You are correct.
I got rid of the updated version by doing a factory reset. You can try loading the older version by first force stopping the loaded version. It may worked... try this first.
I guess a adb edit would allow you to disable the current one. If the older one will load is another question.

I'll see what I can do.
I'll also test the phone again tomorrow when the weather in my city will return to normal. If everything goes well I'll keep the phone, if not I'll have to take it to the store and see what they offer me, a replacement, another device, I really don't know how it works in this particular store that I bought.
Anyway, thank you very much, you've been very helpful!
My 10+ was a battery guzzling hot running hog before I optimized it. It took some time and effort
Today you never guess it is that same phone.
If there's any doubts get a refund. It could be hardware, even a heat sink or pipe issue.
That said this is a commonly seen problem that has nothing to do with hardware in Samsungs.
Do some Google searches for that device and hot running issues. See what you find.

I can relate. I had a Xiaomi before this one, and the stock ROM was plagued with app killing and battery drain. I'm glad you managed to work it out, all I had to do was switch to a custom ROM.
I've tested the same game again today since the temperature has gone back to normal where I live, and while the CPU temperatures are in acceptable range, the battery temperature got to 40°C/104°F.
I did some research regarding overheating on this phone and it's always the same thing, some have it like I do, while others say the phone doesn't even warm up the palm of their hands. So I don't know if its a configuration issue or if there are a lot of defective devices out there.

Slow charging and Android System suddenly eating 47% of battery, 5go send (somewhere) and new Seismic option?

Hi, I suspect this is part of planned obsolescence scheme but, for no reason my GS10 suddenly won't fast charge until I have plugged and unplugged several times with no changes in cable position or port. And when it finally goes to fast charge, and I put the phone to rest, it'll eventually stop fast charging for no reason despite having not moved (but won't change the indicated time, it just doesn't progress anymore).
But also and more worrying, I noticed a tendencies for the past few dies for the battery to die even on idle very rapidly, and when I looked at GSAM I discovered that the Android system was using 47% of my battery, had send 5GO of data god knows where (despite common suspect like Accidental Touch, Auto-sync of data or Adaptive battery being deactivated). Upon investigating option I discovered that a new option in Location for "Earthwake Alert" which I never agreed to or activated (which thankfully Europe is about to make illegal).
I deactivated it, I don't know if it'll make things better, but I also still don't know what kind of compressed data the system has been stealing from me without any input or approval.
Any help or information for the fast-charge and the Android system warez are welcome. Thanks you.
Sounds to me like you have some runaway app or setting causing the problem, more than anything else. Maybe you have malware or a virus as well.
You said you have 5GO of data usage suddenly (I assume you mean 5GB?)... that is what also makes me think you have malware or something. If that's the case, you may want to see what apps you recently installed, as one of them may be a problem. You mentioned warez, so if you're sideloading things, that could be the source as well. I'm not saying that all side-loads are safe, but you're likely are more risk if you don't know what you're doing... particularly if you're using pirated software. Not judging on the piracy, just stating the risk.
With a high load, I imagine charging could be compromised as well. If the battery gets too hot, fast charging will be disable to protect it. If you're phone is getting hot, you have a bigger problem and it's not "planned obsolescense" but likely a runaway app/virus/malware.
I'd say, try a virus scanner (I like Avast, in general) and still look through the apps you have. Something isn't right. What do other battery apps tell you for usage? Maybe they'll see what app is the source of the wakelocks (different apps usually show different results, so try Accubattery, for example, and also check what Android reports itself).

Thanks. Well the malware is Google's Earthquake Alerts Location system which stole 5GB of data from me et run my battery to the ground. I don't what happened, it this infuriates me, because they're literally stealing private data from me.
For fast-charging, I don't know, my smartphone is not running necessarily hot when plugged at home, but maybe the exterior temperature could be a factor.
How did you find out that the Earthquake alerts was the issue? Your previous post didn't have much info to work with, so it sounds like you've tried some other things, so it would help to know what you've found.
It certainly could have runaway from you, but I would expect to see other people reporting the same problem if it's a larger issue.
Do you have any "battery saver" apps running? Those often make things worse, and can cause apps to have to constantly restart, which takes up more power. I've never seen it happen this badly, but you shouldn't need an app killing app... Android does a pretty decent job (often too aggressive due to Samsung's modifications, honestly, but not to this degree).
Do you have a stock ROM? Rooted? Modified in any other way?

I have stock rom, with Alliance X installed which doesn't do much, but yes upon investigating what the heck was going on, I very quickly found this Earthquake Alert thing that was there before, it's the only element that changed.
And also the fact that Android stole 5GO of data which is huge, god know where is just one of many absolutely abusive if not illegal thing that's going to make me switch anyway.
I have Gsam running, but no battery saver besides the developper options set to minimizes processes.
Like I said, it's not likely that software, because if this was happening a lot then others would report it. It still could be happening on your phone, so I'm not promising it's not, but that could be due to some corruption or something on your particular phone. You can supposedly turn that off, so I'd try that... if the problem goes away, then that would be definitive proof. At that point, I'd suspect corruption on your system, which you can try to fix by reflashing the ROM (via ODIN, for example).
Hello ogretactic, the alliance X stock rom you found the tutorial on which forum. Can be seen directly with the person who mounted the stock rom, there is surely an update following feedback from members.

I just updated it. Because I am panicked: my phone ****ing did it again: it's eating 33% of the battery, and has sent 5go of data again. It's driving me crazy that nobody knows how to read Gsam system tracking
Hello ogreTactic, you can find your Alliance X rom on XDA.
See if there is not someone who has traced this battery bug which discharges quickly, perhaps a setting in battery and maintenance of the device.
