Hey everyone,
I seem to be having an issue with the battery temperature sensor. It will always say 30 Celsius even if I can feel the heat of the battery through the case. Is this a known issue with the tabs? Using sensor test, I can see that a temperature sensor works and is constantly updating, showing temps from 30C to 40C. I'm running stock rooted EC02 with KhasMek Voodoo Plus OC 1.4Ghz.
Thanks for your help.

There are 2 main reasons for a constant temperature:
1- A third-party battery is used which have its temperature sensor removed, you will usually see 0.1 variations, like 30.0 and 30.1 at all times. or more often 25.0 and 25.1 (not sure why though).
2- the ROM or kernel is broken with regards to providing temperature to battery apps. Battery apps get temperature from Android OS using well documented API, which have not changed since the very beginning of Android. See here for more information about the API: http://developer.android.com/reference/android/os/BatteryManager.html
Unfortunately it seems to affect a few ROMs now-a-days.
EDIT: Are you using a S3 with CM-based or OMNI (AOSP-based) ROMs?
[Tutorial] [V20x] Disable / Adjust Thermal Protection for Slow AC Charge & Tegra 3
Part 1 - Disabling Thermal Protect during Charging that will result in Slow Charge (USB Current) issue on AC supply
Our LG 4X has an in built function to restrict heat build-up during AC charge, when the phone is already warm after intensive use.
Unrestricted heat build-up will potentially result in damaging chips.
But sometimes even when the use isn't highly intensive under cool envoirment factor the current is still restricted by this somewhat over-sensitive and unadjustable feature. Consequentially when user is using the phone for long duration apps (ie watching movie) while phone is under AC outlet charge battery will still run out, albeit at a slower pace.
Below is the steps to disable this function:
Dial 3845#*880# to enter hidden menu (do not press the green dial button!)
Navigate to 'Module Test'
Navigate to 'Charging Test'
Tick 'Unlimited temperature charging'
Exit Hidden Menu
Charge using AC outlet
If charging cable was already plugged in and in USB current, disconnect and reconnect to see result
Only works on V20x Jellybean ROMs.
Phone restart will return this function to its normal state.
Part 2 - Disable / adjust Tegra auto throttling for thermal protection that will result in game lags during high chip temperature
Besides protecting our devices by controlling heat from charging current, 4x HD also has an inbuilt mechanism to restrict overheating of the chip during intense 3D gaming or graphic heavy applications.
When the heat is detected to have reached a certain level, this mechanism automatically scales down the CPU to prevent anymore excessive heat from being produce. However, scaling down the CPU will also produce significant lag for the user application.
To adjust this function, user will have to follow the guide below:
To adjust this function, user will have to follow the guide below:
Device Requirement: Root, Root capable file browser
Navigate to directory /d/tegra_thermal
Open-for-edit temp_throttle. Set to user preference, typically above 65000
Save
Do the same for temp_throttle_skin
Save
You are now good to go
Settings will revert after phone reboot.
Thanks alekthefirst for his contribution here
USE THIS GUIDE ON YOUR OWN RISK AND DISCRETION. YOU MIGHT DAMAGE THE SILICONE CHIPS / YOUR SIM CARD / SD CARD AFTER PROLONGED USE UNDER HIGH TEMPERATURE CONDITIONS.

i like to take screenshot that it works but how do i take screenshot of heat? lol?
This should show that my phone doesn't switch to USB current when the heat is high
Red = Temperature
White = Percentage
Green = Voltage
Botton yellow bar = charge status
White bar = display on

So thanks for this hint, and bacon joke After all this is MultiPurpose device
is it possible to just increase the temperature ? i think the temperatur protection is very low . Because on v10h never had this prob...
V20B has significantly increased thermal protection activation temperature. To less aggressive user its presense now will hardly be felt.
updated for official V20 release
Do you guys think there's any way to set this, or the changes this implements (it must be changing something, probably in files), into a script or something that could be executed at will (or maybe even through a tool like Tasker)?

on theory there's a file somewhere, but where is it?
The files for that are named temp_shutdown, temp_throttle and temp_throttle_skin found in /d/tegra_thermal, u can change the values, but next boot overrides. Someone could make a script for Script-Manager, which run after boot and set the values new, or sets high and low via widgets (Script-Manager can create widgts I think)...
U have to change the values to about 71000 or more, shutdown should be left as 90000 (setttings in V20a)

doesn't work on charging thermal protection. these settings are for tegra 3's thermal protection by controlling throttle when the heat becomes too high.

I thought we talk about both, disable thermal protection of charging (done via hidden menu) and disable thermal protection (down throttling) on overheating, ur right, thats for more cpu power / less throttling...

ah right, sorry i didn't catch that.
i can add this topic to first post. thanks
updated first post in tegra thermal protection.
i tested
I tested this no change at all as far as cpu mhz cpu still throttles to 1000mhz to one core when playing anything even the gba emulator it starts fine dual core 1400mhz then when it throttles to 10000mhz one core it lags madly after playing for 5 minutes i thought this would work.
edited thermal-throttle to 80000 i assume 80c
thermal skin to 55000 maybe 55c for outer layer of the phone so your skin won't burn.

As i am frustrated with this issue ( brightness falls to 87% and then to 70% after a 10 minutes video playback ) and i am not rooted can you guys confirm that the trick ( Part2) works ?
I ask this because i didn't want to root my phone and this procedure demands root.

for the tegra thermal adjustment you have to be rooted.
btw there's no other phone with easier and safer root method than 4x. and androids are meant to be rooted

I rooted my phone, edited and saved the 2 files at 85000 each.During the procedure my temperature had already dropped to 87% due to high temperature and couldn't go up after the edit of the 2 files.Then i waited for phone to get colder and then i watched a 20 minutes youtube video on full screen and with 100% brightness.The brightness didn't fall !!!!
Thanks a lot for the guide !!!
Hello!
I'm using Z3+ with latest firmware on it (downloaded it with wi-fi). I've mentioned terrible thing, as i suppose. When I browse internet, and watch youtube while charging the phone, the average processor temperature is 55-60, but it sometimes rises to 76 and than drops down.
Tell me please, is that normal temperature for the phone processor? Won't it harm the processor or another phone components?
Thanks!
The heat is wasted energy, most CPU are inefficient and generate heat.
I have a Z2 and a Z3+ (and previously iPhones for 5 years) - the Zs are definitely "hot" compared to the iPhones but the melting point of silicon and solder is quite high (maybe 150C or more).
Remember the days when laptops were too hot to put on your lap? Those machines still work fine today.
So I don't think the device will be harmed from internal heat (aside from more quickly revealing dry joints perhaps) but it may feel warm in your hand compared to other phones. The way I hold mine, I barely notice, all the heat is in an area above my hand. I only notice if the phone was working hard and then I put it straight in my pocket.
FWIW both the Z2 and Z3+ shutdown the camera app after about 30 minutes continuous 1080P recording, however using alternate apps (Better Camera, Google Camera) I have been able to record 1080P for an hour before I got bored and stopped it.
My Z2 records 4K for about 5 minutes, my Z3+ records 4K for about 15 minutes.
It's only the native camera app shuts down to cool off, I guess the image processing works the SoC harder than alternate apps/api.
tl;dr - yes I think it's normal and things won't hurt the silicon and solder until 150 celsius or more - the phone would become unstable first anyway as the CPU mis-computes due to heat.
I think it doesen't matter because it may be occur but if it dont hamper your device then no need to worry about this .Some device like
modem ,laptop and other smart device become heat for a long time use .Thats why dont worry .
Hello, I have noticed that whenever I remove the charger from the phone after a full charge, the CPU stays idle at 1.04 and 1.06 for big cores instead of 576 and 710. It is fixed after a reboot.
Can anyone else confirm and report back the bug?

I can confirm that the bug appears ONLY when I use fingerprints for unlock. When I delete all fingerprints, it is gone. (and in addition, still present in 10.2.28 EEA)

This explains why I got better battery hours after I deleted fingerprints! Not that it was bad before, but now it's ridiculously good!
I don’t think this a bug, it probably must be this way in order to wake up screen just by putting the finger on the scanner.
Having fingerprints registered means that the fingerprint sensor is kept active so there'll be higher cpu usage(shouldn't persist minutes after the phone has been woken) and more battery consumption. Removing all fingerprints( i.e. deactivating the sensor) should give ~10% more battery life but I think having the sensor on at all times even with all its hiccups is more than worth it.

This summer when I started to get the pocket photos, before the .27 was released (yes I was among the ones that got it before it was redrawn) I deleted the fingerprints to get rid of the pocket activity due to the non-existing pocket mode. As .27/.28 came with pocket mode I started to use fingerprint again but discovered that face unlock that I had been using was far more convenient and suited me better despite the somewhat lower security rating. I don’t use Gpay, and do not keep top secret stuff on my phone so I’m happy being rid of the fingerprint sensor. The sensitive economic things are protected by pin-code anyway.
So it was not battery time that drove me to ditch the fingerprint sensor, that extra battery time just came as added value for me!

If you notice, the CPU frequency increase occurs randomly after a period of time, not as soon as you turn on the phone, which seems like a bug to me. In addition, the frequency does not settle down again, leading to less standby time available. So I don't really understand how an active fingerprint sensor affects the CPU frequency after a while, and not since the boot.

If that was the way to be, the frequency should be that high even right after booting.

No, that does not have to be true. I can think of some reasons why CPU speed can't slowdown in order to instantly start the scanner, like for example the more services and apps are started the more CPU power is needed to make the scanner snappy enough. So that may explain why right after boot the CPU may be able to enter a lower idle state. It is in fact true that if you turn off the fingerprint reader you will not have the higher speed at idle state at all, I tested this.
Perhaps there will be a new firmware with a somewhat slower response to the fingerprint scanner that allows the CPU to enter the lower idle state to save battery power. Who knows!
I noticed this as well right from the first firmware update I used (EEA). It's been fixed after upgrading to Android Q's beta modified by Xiaomi.eu, but I don't see much, if any, improvements in battery life, while also witnessing a giant storage performance regression. Hella disappointed.

I get your point but the fact is that in never goes into these lower frequencies again, even after unlocking the phone and idling with screen on, which is strange. I don't get it, really. Plus, you are not able to see in real tilme what process is hooking up CPU resources, as you could normally do in older android versions by using an app.
Ok, if the frequency never locks in the high range again and the scanner starts just as snappy I guess you are right that it must be a bug.

I disabled fingerprint auth, but I don't seen any improvements in battery life.
I notice it on mine as well right now, small cores sitting at 1036 MHz and big ones+super one at 1056 MHz. Can't really put my finger on what triggered it as I've been using the FP sensor all this time and I've checked many times and the cores were at normal clocks (576, 710 and 825). I killed all running apps but it still sat like that until I restarted... at least now I can understand why sometimes my overnight consumption goes from 1% up to 5% even though I always close/kill all apps.

Try rebooting your device and you will see what the actual idle frequencies should be, then monitor it for a day or two! Can't find what triggers it but It's bugged for sure.

Reboot your phone after disabling it, otherwise the frequencies stay the same
I can't be the only but has anybody noticed the phone overheating quickly with moderate gaming or even an antutu benchmark. This is without X mode. When I do the same with my K20 Pro, it doesn't overheat like the Rog Phone 2.
How are you defining overheating? The device throttling? Do you receive overheat warnings?
Just because a phone gets hot doesn't mean it's performing worse. If anything it could mean it has better heat dissipation due to better contact between cooling and cpu. I play dual screen 2 games at once for 3 hours straight and the cpu remained cool around 40C. I kept my cpu speed down because it was overkill anyway

Can feel the heat near the upper left of the back of the phone. Temps were in 40s.
40s is not overheating at all. ROG phone has higher surface temperature than some phones but it's because it's barely throttling even after 1 hour of gaming. No need to worry

Exactly, it's not overheating, it's doing its job. It's moving that heat away from the internal components and to the outside of the phone via the vapor chamber, external vent, and aluminum side body section near the vent. Throw a slim case on the phone if you don't like feeling it warm in your hands, or tweak the game mode profiles to underclock the CPU and GPU and/or lower the thermal limit during games that make it heat up too much in your hand.

Rog phone 2 tencent edition overheating and shutting down
My Phone overheats and shuts down when under heavy load, or while charging while im sleaping. it first happened while playing pubg mobile and streaming my game to youtube. I can feel it gets very hot and after a while it just switches off. i also tried the antutu stress test and when it reaches 5% it switches off, i opened the armory crate to check the temps while antutu was doing the stress test and saw that my cpu reaches 73°c and then again it switches off. this is with xmode off.

Same here. When I play games like ML or any games my phone overheating fast then my screen will turn off ..and another issue when I charge my phone while overheat my phone will shutdown
does anyone knows how to fix this?:crying::
I'm having the same issue. Charging overnight - it gets really hot, and sometimes it'll randomly reset. Not gaming or running much in the background. It happened since the last update prior to the most recent
Keep in mind that Rog phone 2 has a SnapDragon 855+ and + means it's overclocked. While other normal phones out there runs on default speed settings. So that's probably why Rog phone 2 can get hot quickly due to it's overclocking.
Mine gets very hot along the edges. In fact it gets so hot along the edges that it burns my fingers. CPU temp doesn't ever go much above 45 but the sides become untouchable... Is this a feature designed to stop you playing and thus save the phone from melting in your hands? ??

Yep android is a dealbreaker. Extreme overheating cause of the software.
After long time and intensive research, I found the real problem which is cpu/gpu refusing to throttle while on load. Usually the system reduces the clock speed of the cpu to keep the temperature between acceptable working range (room temperature - max of 60°c)
If cpu doesn't throttle, the cpu temperature rises until it reaches the max (i.e 65°C which is critical temperature as per A10s updated thermal framework) and shuts down the device.
I found a workaround which involves reducing manually the clock speed as the temperature increases.
But it requires tasker app(paid) and root to work.
