[Q] what is unsafe temperature for overclocked mytouch 4g? help. - myTouch 4G Q&A, Help & Troubleshooting

I need help figuring out what is unsafe temperature for overclocking mytouch 4g. I have read that overclocking a phone heats up the chips and components of your phone and frys them since there is no active cooling system but I want know exactly what tempereture is specifically bad for the mytouch 4g components and chops. Temperature that can potentially damage hardware permanently at overclocked speeds that way I can set limits on the profiles of the setcpu app

I have been wondering this as well.

Damn, I feel like asking HTC on their website, but last time I asked them a general question they never replied back, and seeing how this is against the purposes this phone was intentioned for I'm afraid I wont get a straight answer. Help ) :

Have you tried looking for a tech sheet on the processor? Possibly available from the processor manufacturer...?

Manufacturers of the processor don't have that kind of information. The one who holds that kind of information is the developer of the phone since they are the ones who limit the processor to fit the need of being in a confined space of a phone with no cooling system. I have checked both HTC and t mobile for detailed information of that in their tech sheets but there is no such detailed information.
I will have to message HTC manufacturers I guess =\

Processor manufacturers typically specify an operating range for their product. The handset manufacturers are then takes with making sure they can maintain the processor within that range, while inside the tiny confined spaces they put them in...
The tiny space doesn't change the processors operating temperature abilities, it just makes it harder for the processor to be kept within it's operating range...

Why does the tiny space change the processors abilities if its not a temperature problem?
I looked for the tech sheet for the processor on the qualcomm website, I couldnt find it. I messaged them so im waiting for a reply. Ill let you guys know what happens.

According to this page, you should try to keep your battery temp between 32F (0C) and 120 F (49.8C). Some copypasta:
As you approach cross 120F on the battery you are actually causing the battery to discharge at a faster rate. Even if the CPU isn't putting a large demand on it.
Getting your Droid's ambient temperature (the whole droid) above 130F for any length of time should be considered a bad idea. The battery itself is the issue. When a lithium-ion battery reaches around 140F, it can enter the state of "self heating" or more commonly referred to as "thermal runaway". Reach this state enough times or holding it there too long and the battery will become unusable as the individual cells of the battery break down from thermal overload.

If the battery is that hot, the CPU is that or more easy.

Awesome find! Thanks for posting this thread, its becoming more helpful than I thought.
Although the specifications for the droid 1 might be different I cant see a new phone like the mytouch 4g being worse in that area. : D
"And remember; my subjective opinion is you don't want to see the battery go over 120F or the CPU going over 135F for any length of time. The reason for this cautious limits reminder? Lithium-Ion batteries can reach thermal run-away at 140F. The CPU can handle up to 170F but the mother board holding it and the components around it are only rated to around 154F. So staying below both will help you stay happy with a working Droid."

crazy overheating

I have had atrix about a week now and I have been having some extreme overheating issues. After about 15 minutes of watching a youtube video, according to temp monitor lite, my cpu temperature rose to about 55 degrees celsius. Is this nnormal? Or should I as for a replacement?
Thanks.
There us several threads about this....
And its normal idk why.
Mine its at 55 or more and battery get like 43+

Yes, it's hot, but apparently it's normal. Scares me when it gets that hot, but I haven't heard of anything really bad happening to anyone or their phones.

Are you people saying its normal .. as in a lot of people are experiencing this?
Or
saying its normal as per Motorola saying its normal?
If its the first option, I would hardly think that is safe. Ever think its a device wide ISSUE? Unless Motorola say that the device has no issue running at those temperatures, then I would really doubt it is normal.
Do you think this phone has some sort of unseen substance in it that prevents it from being damaged at this kind of temperaturewhich no other smartphone has? There is no extra protection for the sim or memory card. Which obivously are not meant to deal with excessive heat

If the phone had active cooling for the processor (like a fan, hahaha.) and it still "overheated" then that would be an issue, otherwise you're looking at a 1GHz phone with twice the cores of any previous phone at the same clock speed. What are you really expecting?
I dont agree that its normal for the phone to get hot regularly, i definitely wouldn't put up with "crazy overheating". And I dont use my Atrix moderately either, I'm constantly on it. TiBU tells me I have 417 system/user apps as an example of my extreme use. There are a couple other threads on this subject, op you should search them out. WatchDog will monitor your apps and let you know if any are misbehaving.

From Motorola:
"It is possible phones will become warmer during heavy use. This is normal behavior especially if you are transmitting data, talking for an extended period of time, or playing games or music on the device. In these conditions, the phone is transmitting and utilizing alot of power on the device which will generate heat.
Motorola phones manufactured in 2009 or later have a "cool down mode" function. This feature is designed to protect the battery and circuit board. If the internal temperature of the phone exceeds 136 degrees Fahrenheit, the device will shutdown all functions except emergency calls. When this happens it will display a cool down mode message. Once overheated, a phone will not regain full functionality until the internal temperature drops below 136 degrees Fahrenheit. Ensure you are not leaving the phone in locked cars, in direct sunlight, on warm or hot items such as heaters or radiators, or any location that produces heat that will heat up the phone."
If it gets hot while charging the battery, and doing nothing else, there is a problem.
Now, please don't give up your day job, because being a smartass isn't working for you! Don't let the doorknob hit ya where the good lord split ya on yer way out!
My phone has never been over 105 degrees Fahrenheit and that was only because I was trapped inside a black car for 30 minutes with the AC turned off and it being 95 degrees out :?/

Ok .. you showed a critical threshold of the phone. Do you think pushing the phone to excessive heats but staying below that threshold is good for the phone? Notice that it doesn't mention how SIM cards and memory cards will continue to respond when being exposed to excessive heat with no ventilation or circulation ..in fact your quote clearly says that feature is for the bAttery and circuit board
Bottom line..
you can push your phone to 130 degrees (since that's below your shutdown threshold ) and I will spread out my usage and keep my temperature down to a minimum ... and my phone WILL last longer than yours and I WILL have less issues with it.
Highest my battery has ever got is 48c
highest my processor has ever been is 63c
was the phone hot? probably.
processor normally sits at about 45-50 in my cardock as per what setcpu says
battery sits between 40 and 45 in the car dock.
Watching a movie in the car dock whilst my kid was in the car setcpu says it hits anywhere between 55 and 60.
It leads me to believe that the max operating temperature for the CPU is right at about 65c, and teh battery right about 55c.

So you are basically talking about the SIM card and memory card on all phones which are going to come out with dual core and no active cooling, cos they are all going to get hot. What Motorola has stated is what any manufacturer would and does. They have given us their safe operating threshold. Now, 136 degrees is a lot, but how much of this heat affects your SIM card and SDCard? I don't know, and you have provided absolutely nothing to substantiate your personal claims. Bigger doorknob needed I guess!
I simply responded to the OP telling them it's normal for this phone to get hot. If you want to continue down this avenue we can, but until you have something from a SIM card manufacturer and SDCard manufacturer substantiating you claims, I'm done.

Considering the memory card and SIM card are not far from the battery and are trapped under a cover... a lot of the heat would be affecting them as well. When did I say anything about dual core at all? I don't think I even typed those words out.
Point is that I don't know if most of these people are even doing enough tasks on their phones to even get TWO cores aggitated enough to put out that kind of heat. All of my other smart phones were pushed much more than this and have remained pretty cool to the touch. Even one with a metal battery cover.
I was more replying to the many posts across the ner and people I know that have the Atrix heat up too much and for too long.
As far as OP goes..
"I have had atrix about a week now and I have been having some extreme overheating issues. After about 15 minutes of watching a youtube video, according to temp monitor lite, my cpu temperature rose to about 55 degrees celsius. Is this nnormal? Or should I as for a replacement?

When you're streaming video the heat will increase, but make sure you dont let it stay hot for increased periods of time. You dont need to request a replacement unless you are experiencing excessive heat frequently.
Also, when streaming - try not to have GPS and other things like that running in the background.

[EXPERIMENT] S4 Overheating and how it affects battery drainage [PLEASE PARTICIPATE]

Dear Community,
In this thread I want to gather a sample to investigate to what extent the S4 suffers form overheating and how this affects the battery drainage/life. I urge you to participate as I am collecting a sample to submit a formal complaint to Samsung to raise awareness to an issue that is widespread among S4 users and to push Samsung to address this issue accordingly. In order to provide your sample please follow the instructions below and report back in this thread with the relevant information. Please first indicate which variant you have: Quad/Octa (i9505 or i9500)
Please download BatteryGraph (it's a great app to measure Battery drainage accurately) https://play.google.com/store/apps/details?id=com.modroid.battery
Run it once after download to initiate logging. Let it run for 10 minutes to allow the graph to built up a bit.
Then please Download Antutu benchmark run the benchmark fully exactly 5 times back to back (continuously). After that please enter the stock dialer (as quickly as possible) and enter *#0228# and post the temperature (external thermistor) after the tests in order to determine the maximum temp that the device reaches under continuous stress.
After that, please enter the app Battery Graph and zoom into the graph to the maximum level. Scroll slowly along the curve at the time when you performed the Benchmarks and tell me if there are interruptions or 'skips' where the battery drops 1 or 2 percent at a time and where the App does not Register a graph for those drops. Sequence/scroll slowly along the graph 1% at a time and make sure that the battery dropped 1% at a time. Please report of the battery has dropped more than 1% at a time. Please make a screenshot of your battery graph in the App and post it here for collection. I will analyze the graphs subsequently and compile it in SPSS to submit our findings.
If there is a drop of 2 or 3% at a time it means that you are experiencing Battery Percentage skips/cliffs which could indicate either a defective battery or defective device which might be the cause for the extensive heat development.
Thank you for your participation. Hopefully Samsung will listen to us and address the issue to give us the perfect S4 that we deserve.
Best,
Thomas from Germany

That battery app polls for battery level changes every 5 minutes by default. I think almost every device will experience a drop of more than 1% every 5 minutes under constant stress testing. You can change it to poll every 1 minute in the settings, which you might want to mention, but even so isn't it entirely possible to lose more than 1% a minute with everything turned on (GPS, Gestures, etc.) and ~17 minutes of constant cpu/gpu stress testing? It's a nice idea but it doesn't sound like it would yield very accurate results, unless I've misunderstood your post.
EDIT: Nevermind, I see how you can step through it 1% at a time now.

I've also noticed that you cannot really zoom in very far and at the highest zoom setting the % is still displayed in multiples of 10. Kind of tricky to differentiate between a 1% and a 2% drop.

You might be right, what would you suggest in order to yield more accurate results? I suspect that the heat is directly linked to a very quick drainage of the battery. How can we measure how much it affects the actual battery drainage?

I'm not criticizing you or anything and I'm not saying it's a bad idea, It's just that obtaining accurate battery results are tricky as everyone's device is different, has different settings enabled and are running different kernels/ROMs/etc. Batteries also seem to get more efficient as time goes on so newer devices might suffer from higher battery drains.
I'll run the battery temp test now though and see how hot mine gets!
I like your critical thinking, obviously you are right it is very trick but I believe the heat test itself could be very indicative. In the meantime I will try to find a better way to measure battery drainage.
So everyone please try to run the benchmark multiple times and submit the temperature.
The most I was able to get was 52C
Thanks
Pre-test: 29.9°C
After 3 tests: 35.0°C
After 5 tests: 37.7°C
After 7 tests: 38.4°C
After 10 tests: 38.8°C
The temperature increased less and less so I don't know how much higher I could get it.
Also, an easier way to poll the temperature is to do "adb shell dumpsys battery" over ADB. The temp will be displayed as something like 388 which means 38.8°C
Edit: It might be worth noting that the top of the phone, around the camera but more so on the screen side (so the cpu?) got incredibly hot. Almost too hot to touch. Kinda worrying, but I have spent the last half an hour stress testing, I guess

Thanks for your contribution Meltus! Really appreciated my friend. Also thanks for the ADB command it does make it easier but I doubt that you've read the correct temp as 38 appears to be quite low compared to what i got. Is your S4 a i9505 ?

It's also the temperature that dialling *#0228# gave me (I double checked they were both the same each time). And no, I have an i9500, running Omega ROM, if that helps.
Might want to mention the elementary precaution of taking off all case covers except for the stock case before testing to prevent insulation effect of case covers increasing battery temperature...
While you're at it you might want to standardize room temperature to 25 degrees C... I know for a fact that my device would never get hot no matter what it does if running in the freezing cold air-con'd metro...
What about brightness settings and whatnot. Should all be the same, so you have to give a standard.
Pre-test: 36.2°C
After 3 tests: 51.4°C
After 5 tests: 54.6°C
After 7 tests: 56.9°C
dafaq right??? im really annoyed at sammy for this overheating S4... after 7 times testing the Antutu, i stopped and LITERALLY put my S4 in the lower compartment of the refrigerator to get it cooled down quickly cause im pretty sure the heat sensors inside would definitely be having some testing errors and the temperatures would be really really higher than that. even when i swipe between different homescreens the phone gets to 47°C which is really annoying.
can someone pls for the LOVE OF GOD provide any solution to this freaking problem? i have been worrying a lot for spending my $730 on an overheating phone...
i have S4 i9500 Exynos version

Are you talking about the battery temperature? If so something is extremely wrong with your unit, my battery temperature never went past 45 even with high stress.
If in case you are pointing out the cpu temperature then there is no reason to freak out because the cpu can handle upto 90c + and can cool off pretty fast
Edit:
And why on earth you ran Antutu for 7 times continously lol? None of the current generation phones can handle it for 7 times on a row afaik

and why would it be silly to run any app 7 times on the flagship device? its made to run the apps as much as people want thats why we pay a huge amount of money for these devices dont we? or else we should buy the low end devices
just saying cause i had heating up issues with devices before infact my last device Note 2 used to get a lot hot but not as much as this S4...

You are not buying a flagship device just to run Antutu n number of times, do you? yes I accept we do pay huge money but that doesn't mean we can push the limit of a mobile and complain about it from a general user perspective . , it can be only done for experimental purposes and to understand the power /thermal envelope provided that it's done in the right way.
But how does running Antutu 7 times matches a real life scenario? Highly unlikely isn't it?
We are already pushing the limits of raw cpu power for a mobile, raw a15 cores are power hungry and often tend to heat faster than previous generation. Hence arm introduced the big little. The mobile heats up during heavy stress, but but that's expected with these powerful cores right? I'd better utilize the power wisely when needed rather than using it all the time. The cpu indeed gets hotter when stressed, it's the same With my s3 too the cpu temps reached upto 80,there is built in throttling mechanisms which will take of the cpu once the cut off temperature is reached. Have seen many benchmarkers these days using freezer test due to the thermal throttling in new gen devices. Yes the s4 heats up pretty quick than other mobiles but also cools down pretty fast and I think that's the way it is destined to work.
Hei one more thing, did you note how long it took to fallback to normal temps?

We were doing it to see if there was a correlation between excessive battery drain and overheating batteries. Mine never got any hotter than 40 and I have pretty great battery life. The OP was seeing temps of 50+ and I'm guessing he has poor battery life.
Could there have been a few batches of bad batteries sent out with devices?

Battery temperature. If someone's experiencing temperatures in excess of 50C and bad battery drain it would indicate a problem.

Hi,
Soon to be RC here, and my first contribution to the nexus 4 world is an attempt to convince you that your nexus 4 isn't overheating.
Some of you replied to my first thread here about what should i worry about in the nexus 4. Some replied that it has a battery drain... that i fixed by removing the google search bar... Others have said that it has overheating issues which some users are scared of.
I'm here to show you why you shouldn't be scared at all.
I was playing Fast And Furious 6: The Game, and 5 minutes later when i ran out of car gas, i closed the game and directly opened Trickster MOD app to see the temperatures of the phone... yes temperatureS.
You'll notice there are two temps in this app: Battery Temp and CPU Temp.
The one you used to check on older devices is Battery Temp, because older devices didn't have CPU Temp sensor.
When i first opened Trickster MOD it showed this:
Battery Temp: 42°C
CPU Temp: 56°C
And then seconds later, the CPU Temp dropped to 49°C and stayed at 49-50°C.
But Battery Temp was decreasing slowly from 42°C to 38°C in about 5 minutes.
Now the reason for the fast CPU Temp drop is that when the CPU is busy, there is so much electricity running through it, it generates heat. But when the CPU is practically resting, the electricity running through it is much less, hence, the Temp drop, which is normal. And also, if you're using a kernel that supports turning off the 3 other CPUs when not in heavy use, then it's better because the less CPU cores active, the less heat.
So the main thing you should be scared of is the Battery Temp... But don't be, because Android is smart:
Android has a built in overheating system which does certain steps to avoid hardware heating damage, if the phone overheats, it takes some steps:
1- If charging, it stops charging to reduce Battery Temp.
2- Reduces CPU speed automatically to make less electrical current run through the CPU, thus reducing CPU Temp.
3- If both of the above failed to get out of the overheat situation, it shuts down the phone.
So if you were playing a big game, and the phone heats up... keep playing that game, android will take care of the rest
OFF TOPIC:
But the question still remains: if I'm charging the phone using the wall charger, and I put it on the wireless charger, will it blow up?
Well, yeah. This is what we have been trying to say since the Nexus 4 came on the market.

i like what you wrote, except for one thing..
"So if you were playing a big game, and the phone overheats... keep playing that game, android will take care of the rest"
the use of the word overheats. its not overheating. its heating up with use, which is the normal way things work. by using overheating, you make it still sound like an issue.

Good topic and solid explenations.
But, Do you think theres a chance the glass back will crack if the phone is at its hottest point(right before it shuts down itself)?
Because I remember that I've read these horror stories before I bought the N4, don't really know if its bad luck or not.

if you drop it in cold water, or stick it into a good freezer at that point, then yes. otherwise, probably not unless it get cooled down extremely fast.

Glass doesn't break/crack because of heat, glass breaks because of the fast temperature variation... in this case 2-4°C max is the variation, so no

Thats true, thanks for clearing it up!
Also android itself doesn't have anything built into it for thermals.
That is done by either a file like thermald or on a hardware level.
It's like saying windows controls the cooling on your pc.
A device example would be the rlod. Lower level stuff. Android isn't even loaded.

you're right, it's not "coded" into android... but so far every android build i've seen has that security system.
but that's not the point, the point of this thread is to stop N4 users from posting "overheating issue" posts, and not worry anymore.
I hear ya. But I am going to rain on your parade. It will never stop.
At best ( which I doubt) they are children that simply don't know much.
But the truth is they are plenty of fools and it will never stop. The level of stupidity I have seen related to this discussion is appalling.
Only way it will stop if it becomes taboo. One thread in general and any new threads about it get closed down and deleted.
Actually it is android that controls temperature throttling. Or to be more precise the android kernel. Which reads the thermald file for it's Max CPU temperature.
There are also hardware cut offs 100°Cpu and 60° battery which will power off the phone.
These temperatures are what I consider overheated. Anything below or throttling is to prevent your device from overheating

[Q] Overheating

Does anyone have overheating problems with their GS5?
Nah i dnt. Mayb u run to high frequencys or do it while charging?
Sent from my SM-G900F using XDA Premium 4 mobile app
When it charges it will overheat, that's standard protocol. How are you charging it?
I have tried both wireless charging and wired and I conclude that the wireless charging heats it much higher than wired. If you think it is getting too hot: download some battery app to check your temperatures and statistics.
Don't ****ing overcharge the phone either.
If all fails: just hold in under the tap a minute, should cool down pretty fast.
Nopes. Barely noticeable when gaming. For usual stuff it's all good and cool.

Highest temperature I've gotten was 97F. When I'm using it hard it will sit around 88-91F.

Sure. Is that all you wanted to know? That doesn't seem like a particularly useful datum, but it's your nickel.
If by chance you wanted more details or information, perhaps you could add more details yourself? Do you think that your S5 overheats? Why do you think that? What actual temperature does it reach? You really haven't provided nearly enough information for us to understand why you are asking.. or what you hope to learn.
It's normal for a smartphone to get "hot" under load. It's also a meaningless adjective without a context or quantitative measure. I don't believe that Qualcomm or Samsung have released thermal specs. But it isn't hard to estimate a thermal envelope.
My S5 idles around 30 - 35C. Light use sees 45C and perhaps ~65C under load. Which doesn't concern me at all. PC processors can see 90C+. I wouldn't worry about a phone that stayed under 75C. The processor will almost certainly auto throttle if it exceeds TDP in any event. TDP is rumoured to be ~ 5 W for the 800 series Snapdragons.

❄ The LG G4 TEMPERATURE THREAD ❄

We all know why LG choose 808 over 810, now let's see the results of their choice:
Here we'll talk about the G4 operating temperature.
Try to indicate your ambient temperature, model, display brightness, app(s) used, your cpu utilization (I use cool Tool for it), and of course temperature (for that purpose I use Cpu Temp wich basically reads bms sensor of Cpu-z in overlay, and Cpu-z itself) ;
Remember to distinguish battery temperature from cpu sensors temperature and if using cpuz remember that temperatures are very sensitive to time so measure it only while performing the task wanted.
Keep it as scientific as possible
*I forgot to mention that CpuZ has an erroneous C to F conversion. So keep it in °C to be accurate
There is an intersting heat comparison HERE on Android Central to begin with
Good idea. Do note that CPU-Z seems to have a bug where it converts temperatures incorrectly from C into F, in the Thermal tab. From what I've seen, CPU-Z should be set to display in C, not F, if you want accurate readings.
To see the issue, check the temps, including in the Battery tab, then in the Thermal tab. For me, in C, the Thermal tab numbers seem reasonable, and the "battery" line in Thermal is close to the temp shown in the Battery tab. But change the units to F, and the Thermal tab suddenly reads the battery, and everything else, too-high by about 30F. The temperatures are not converting properly from C to F, the displayed C and F values are not equivalent. This conversion issue appears using CPU-Z on my last phone, as well.
So if posting CPU-Z temps from the Thermal tab, I'd suggest setting it to C, not F.
Thanks, I forgot to mention it, added
What's the point of this thread? This isn't a PC, it's not like we can do anything about the temps.

That is where you are wrong. It's called we can hard mod the phone for better temps.
Total newbie question, is the temperature you're feeling on the hand the one from the CPU, or the one from the battery, which is closer to the hand?

It should be the battery because I notice my phone getting warm pretty often and I have a widget for battery temperature which tends to go up to around 38 °C often. I didn't check CPU temperatures but I don't think the CPU is heating up too much.
82 F - sitting on the desk doing nothing but looking pretty. VZW, brightness at 0% and Auto.
All these freaking temperature problems will be resolved in a few months when the freezing winter arrive xdddddddddddddf

Lol, no, you can't.
At least LG choosing 808 instead of 810 due to hear issue was the right choice.
https://youtu.be/HltGLYZLySs
Take a look at a link above, SD810 might have upper hands during cooled state but that changes quickly throttling down below SD808 specs. SD810 potentials are pretty much obsolete and probably will never run on full more than 5 minutes.
SD808 is holding its speed even running hot. So I wouldn't really worry about hear part for this phone. But I'm with some users here. Few software updates will iron out some heating problems.

I've noticed that phone is getting hot when charging even if the phone is in standby. I'm getting around 40-44c.

That's low for charging honestly if your referring to cpu temp. Most phone cpu temps stay around 25-35 idling and mid 40s when just doing simple scrolling and small tasks. 60-70c is fairly normal on heavier tasks and games. Kernels usually don't even start throttling until the cpu gets in the70-80c (generally most start shutting down cores at 80).
That being said, my G4 is one of the coolest running phones that I've messed around with. CPU-Z usually says that I'm in the low 40s even on some heavier tasks. I know that my Note 4 gets much warmer, much faster. Heavy web browsing for example will have my N4 in the upper 50s low 60s. The G4 stays pretty stable in the upper 40s low 50s. I'm happy they chose the processor that they did honestly. Stays pretty cool compared to the competition.
you can even mine cryptocurrency on this beast for hours on a normal (here normal) 27-30°C ambient temperature, and the battery gets to 44°C and the CPU gets into the 50s.
This phone has one of the BEST thermal management I've ever seen. I was a nexus 4 user, so you can see how much i was struggling.

Thank you all
Please add which sensor are you referring to and with wich app you use to read sensors

I don't pretend to be rude, but that information is outdated and inaccurate. I don't know how the other manufacturers are doing with the 810 to be honest, the Z3+ is sort of new and I've been checking the threads but there's too early to judge so far, it happens that I do have an HTC One M9 up to date, stock and unrooted and I've noticed several improvements through updates. Considering my daily usage I didn't feel this was matching with what I experience in real life, so I decided to redo the test on the video. I ran AnTuTu benchmark 64 bits version 4 times in a row, and left an average of a minute (sometimes less, once was a bit more cause I took the wrong screenshot) between tests. The attachments were uploaded in chronological order, you can also guide for the hour displayed from the device.
Now besides the video only runs 4 times, I did notice it was holding every couple of tests and then decreases, so I decided to run one more for the sake of pure testing and check throttling behavior, and surprisingly the fifth run gave me an increase on the score instead of lowering it further.
I didn't find a dedicated benchmark thread on the G4 forum, unless LG had improved a lot the 808, and based on the several benchmark results you'll find across the internet, including the ones in that video, looks like even throttling snapdragon 810 holds as an 808 in worst case scenario.
About heating problems, if I'm providing a success case scenario with a more troublesome chip like the 810 is, I'm completely sure the 808 will be fixed in time
phone gets crazy hot when running Periscope
it even shows that hot temp message / stops charging
try broadcasting for 5 mins
Intersting comparison between M9, S6, G4, Droid Turbo heat dissipation HERE
Periscope heats up the phone like crazy!
I too have had issues with the device getting very hot on the top half of the screen. Tried a couple of factory resets but it didn't help. Even reset one more time and kept it stock after a few hours same problem. Took it to the AT&T store and of course it was behaving fine. Luckily the rep knew me and accepted I knew what I was talking about. Swapping mine for one first thing this morning when their new shipment comes in. Will update if issue persists or not.
Wish I would have done it 3 days ago. Might have been snagged another battery and leather case lol.
