The problem is, no matter what program I use, if I set the Tab to downclock at 100/200 or even 100/400 when the screen is off, the phone will freeze in sleep and force me to reset the tablet pressing the power buttornfor 7 seconds.
Anybody else have this issue?

do you use SerCPU?
I set is 100/400, it sometimes work but my phone was getting random reboot.
So I disabled it...

same issue with me , if I set the cpu to 100 to 300 it would hang or crash coming out of sleep mode . I ended up removing setcpu and going back to stock . i expect the Cooked roms will resolve this later on .
Probably kernel related. If i select the Set On Boot option, after a reboot both min/max freqs will change to a min of 19 and max of 500. Probably best to leave it until we have devs working on it.

there's really no need to underclock when the screens off, you know that right?

Get an app to graph the cpu use, and you will see the cpu spike when sleeping.
So, in short, yes: downclocking with the screen off really help the battery life

It doesn't make much difference as the cpu scaling does a more than adequate job, but whatever wets your whistle
Hi guys, I asked my dad to buy the TF700 (this would be my first tablet) in my home country because the model hasn't been released in the UK (it should be today) and it's cheaper there. A friend of mine will be bringing it to me when he comes back from summer holidays.
So I've had him do the proper inspection on my tablet (according to this thread) by alienedd), and so far the tablet has passed most of the tests. But just now he noted that the tablet feels a bit warm (in particular at one of the corners of the tablet), considerably warmer than the iPad (he has been reading blogs and watching youtube HD videos using the tablet).
I wonder what kind of normal temperature should I expect for this tablet? and whether I should be concerned with what my dad noted.
Thanks in advance!!

What sort of tests was he running? High performance activities like certain games will push the temperature up. it could feel pretty warm, but will cool off before damage is done.
Just web surfing, and typing this, my TF700 is running at 25C.
My top left corner of the tablet (where the power button is) gets a bit warmer than other spots while watching youtube videos.

Just have him install Cool Tool @ playstore. You can set it as a floating widget. It monitors everything that you choose it to monitor. I have it monitoring battery temp. CPU speeds and WiFi signal strengths. This will help you determine much more accurately if your temp is getting to extreme. On my daily use with my Infinity, my temps never go above 100 degrees unless I'm pushing it with heavy gaming.

With brightness set to ~20-30%, I normally see room temperature + a few degrees, basically 24-27*C, sometimes more, sometimes less.
With brightness set to max. and in some sunrays at it, I was getting as high as 41-47*C.
Edit: I meant the battery temperature, as this is what I have monitored in the tray.
The tab I have shows 120.07F degrees right out of sleep.
Then after browsing it ramps to 140.00F degrees in balanced mode with nothing forced.
Never seen the temp above 140.00F
I use system tuner to look at the CPU temperature.
I guess SysTune is accurate...I wouldn't know if it was lying anyhoo.
My previous Acer tablet was returned because it was showing temperatures in the 195F-225F degree range with below normal use.
That thing started crashing all over the place.

Sooo if my tablet is at 102F right now just from browsing websites (5 tabs open) do you guys think i should try to exchange it for another? It got pretty hot yesterday when i played zenbound 2 for maybe 15 min. Brightness on about 2,% performance mode to get it to stop altering screen brightness ( auto is off).

I just played ShadowGun for 10 minutes then quickly checked temp and found it was only 93F in ~80F ambient temp. Highest I've seen on my tab (outdoor use) is 118F during the hottest part of Midwest summer when it was 100+F for days on end. Based on my experiences, anything above 120F would seem a bit abnormal.
Just checked mine using System Tuner and it was at 120F after short use of Tapatalk, etc... I believe this is completely normal - its not even warm to the touch on the outside...
For those that say it theirs never even reaches 100 degree F, what are you using to check the temperature?
EDIT: Ha! Cool Tool reports 95F while System Tuner reports 127F! Obviously, one of them is wrong - or one is monitoring CPU temp and the other is battery temp. Guess we need to clarify which tool is reporting which temp...

That doesn't sound right. Your tablet would literally be smoking and smelling if it were that high wouldn't it?! Having it functioning alone with such high temps shouldn't be possible. It will literally be too hot to touch and would definitly fry your cores? Mine when it reached 104 degrees F. It was hard to hold due to the amount of heat. I can't imagine temps going 140 and above!

I don't know what to tell ya...
It's hit a 140 a few times as reported by Sys Tuner.
I've done some resetting in System Tuner and have gotten the temps back down.
Out of sleep I'm seeing 103 degrees now.
It still hits 140 occasionally.
I can tell when it's cooking because the area under the back camera gets warm.
Like I said in my original post I wouldn't know if Sys Tuner is lying to me or not.
Yeah, I think Sys Tuner is reporting the temperature wrong - like I said, when SysTuner reports 127F, Cool Tool reports 95F, so something is way off - probably Sys Tuner is wrong is my guess...

Blah guess this one is going back to best buy.. I was using Cool Tool. The back was burning hot and during the middle of me editing my last post to say I was using Cool Tool the tablet crashed and went through a few boot loops until it finally loaded back up.. The 102F temp was just from have 5 tabs opened on browser, using the tablet indoors, almost full battery (just turned on), 20% brightness. I switched it back down to power saving mode just to see and the past few hours it's been at 93-98F from just 2 tabs opened on browser. No games being played since then. I also had it fully off for a few hours in between.
P.S. Do you guys know what serial number your units start with? Mine is C7. At the best buy besides the other C7 I opened the day before (had scratches) the rest of them were C6. Wondering if the batch makes a difference.
I don't think 100F is out of bounds for this device - like I said, mine was at 95F just using tapatalk. Having 5 tabs going in a browser would certainly make it run hotter than Tapatalk...
EDIT: Just out of curiosity, try loading Dual Battery Widget and see what temp is reports...

makes me miss my original prime. I could have 2 browsers with multiple tabs up, checking gmail, playing games, on performance mode (to get away from screen changing brightness even though auto brightness off) and it would only get warm. Now if their updates didn't break my gps and make my screen bug out all the time..
What does dual battery widget do besides monitor battery? I installed it but it just logs battery right? CoolTemp is still at 91F right now. 100F was whatever for a powerful tablet since my laptop burns my legs normall, but once it got to 102+ it started going through boot loops from overheating.

How do you get it to show the temp? On the bottom right it just shows a battery icon, and when you click into the widget it just shows a line graph of the current battery % of the tablet.. while the system menu on bottom right shows the dock %.

Umm how to do you create a widget? It's not listed in the widgets tab on app screen.
I've been searching around for a bit and cant find a definitive answer on the affects of performance mode on the infinity (Not rooted, running stock). I wanted to get everyone's opinion on how exactly it affects the OVERALL performance of the infinity.
Is the trade off worth the decreased battery life? Does it alleviate some of the lag we sometimes see in battery saving and balanced mode? What areas ( browsing, app draw animation, switching between home screens etc...) do you see the greatest increase in performance?
Also i don't really care about the different benchmark scores that are out there. I want opinions on EVERYDAY USAGE, not benchmark results. Thanks in advance guys!

Battery life is still great and I get really good performance with Dolphin and good performance with Chrome.

Good question...
I don't see much difference tween performance and balanced.
Gaming is a tad better in performance maybe because it pushes the GPU a bit.
As far as everyday use and battery life not much more speed in performance.
Just another button to push versus a root tweak.
Hmmm, OP - why not just try it yourself and see?? Who would be a better judge than you, on your own device, using the apps that you use??
Everyone uses these tablets differently and just because someone else gets better results with their setup, doesn't mean that you would see the same results...

I have tried it, but obviously im not the only one who owns a tf700, nor is my use of the tablet the same as everyone else. Also there have been obvious differences in individual tablet performance regardless of performance mode. Hence why im asking everyone's opinion. That way i can compare my results to those of everyone else and see if there is a correlation. Cant do that by just looking at my own individual results

If you want good performance you need to at least root your device.
as far as cpu speed goes, all performance mode does is kick up the max from 1.5GHz to 1.7GHz. in power saving mode the max is 1GHz. not sure about gpu changes.
i tend to use power saving mode unless im playing a resource intensive game, which honestly doesn't happen all that often. i don't really see a difference between the modes as far as changing between home screens, launcher drawer, etc.

I appreciate the response. Very informative. What do you usually use your tab for?
Sent from my ASUS Transformer Pad TF700T
If its like the 201 which I assume it is then:
Performance mode has higher maximum speed and is more aggressive with powergating. It also has higher contrast and I think faster bus link speed. 3d speed is best at this setting.
Balanced will scale to quad core but will be more hesitant to hit high speed and ungate cores compared to performance mode. The net is a slight stutter. The contrast is lower. 2d balanced performance is the same as performance and powersave is about half the 2d speed.
Powersave is more conservative with speeds and gating. Is good for video playback if you can get over the dynamic contrast which is higher in this mode.

I've had noticeable lag in balanced mode while watching 1080P video. I get zero lag with performance mode. I also notice the graphics frame rate is smoother and higher on performance mode as well. Especially when you play games that totally utilize the tegra 3 chip set.

Most of the time I've spent with the tablet so far has been flashing roms (stock based and cm10 testing which tends to be very time consuming lol) and tweaking stuff. When I do actually USE it, it has been for media consumption most of the time (displaying photos for friends that are over, reading ebooks, looking up something on the web, reading XDA, etc). Nothing really resource intensive.
Stock, non-rooted, not unlocked, no tweaks, turned off most bloatware. Running a Live Wallpaper (Steampunk Droid). Have had it since about a week before the release. (yes yes, the store cheated.)
My everyday use is mainly: checking mail, typing documents (books), watching videos (tvshows, films), working in Photoshop Painter and Sketchbook, reading pdf magazines, playing (non-casual) games, reading 9gag, vlc remote, design presentations, playing music, webtesting layouts.
From what I've noticed:
Power Saving:
Delay in loading apps, changing screens, scrolling and swiping (4-5 seconds to load the icons on homescreen). Typing (120wpm) on the dock keyboard drives it completely insane, I have to wait about two minutes for it to finish catching up, and it usually ends up as complete gibberish; Highly amusing, but not very useful. Videos of any size pretty much won't render properly at all. Websites take quite a while to load. Saves the most battery in sleep mode (+-1% loss over 10h wifi off)
Balanced:
Smooth screen transition, appscreen loads (almost) instantly. Lags slightly during intensive use (typing with keyboard, video loading, heavy games, multiple browsing tabs). Videos work alright, anything over 720p won't work properly, Tegra3 games lag (fps of about 5). Ordinary games run fine.
Performance:
Bit more snap-responsive than Balanced, by a fraction of a second. Not vital, still noticable if you're looking for it. Blurays run (more or less) smoothly (ICS isn't designed for it) (tested with Timescapes 4K bluray 1080p mp4 in VLC Béta, it ran the video for 8 hours on high brightness&ips+ with dock connected.). Heavy games (MW3, NOVA3) run fine. No delay between swiping, switching screens or launching apps.
There is no difference in screen contrast or brightness between Balanced and Perfomance as far as I can see.
Personally, I use Battery Saving when I put the device to sleep or on idle (the occasional email it can handle just fine). For normal use, I go for Balanced mode. If I notice it is a bit sluggish in games and videos, I switch to performance for the duration and then just swap back once I'm done. Using performance for anything other than when it has trouble rendering is a waste of battery and power.
Hope this helps.

I want to start a bounty (if there is even any interest for this?) to disable the screen brightness throttling.
Now of course I understand people say "oh it will damage your phone" but you know what, so will overclocking your processor and graphics etc.
My problem is that whilst not even doing intensive tasks, my screens maximum brightness lowers, apparently due to temperature throttles. It is really frustrating because sometimes the phone does not even feel hot, and I'm not even using the phone intensively.
Even if there is no interest in this, I'd happily pay someone to increase the temperature throttle for brightness reduction.
Many Thanks

Maybe you have it set for automatic. I have have my auto setting turned off and set to full brightness. It has never changed or become dimmer and I play a rather demanding game for an hour or more at a time.

It happens on the Snapdragon model 9005 when auto brightness is off, brightness is set to max and under heavy load. Even worse if you are charging the device at the same time.
There are other threads confirming brightness throttle.
Hell, I even got a message in brightness settings to say it.
Sent from my SM-N9005 using xda app-developers app
yes, brightness (and CPU) throttling on ALL N9005 devices is fact, although some perform better (later throttling) and some not, which maybe has something to do with CPU-binning (search for that, the higher the number the lesser the voltage, less voltage means less leaking current > lower temp under load) i'm sure this is kernel related, so theoretically it should be no problem to disable it with a custom kernel!
due to "display problems" i switched through 6 devices, 2 of them were noticeable better in regards of throttling... as always with consumer devices: it's a bit "luck of the draw" which device you get...
I have to agree with the others, I have never seen that message in normal use. The only time I ever experienced that message was when my phone was in a car holder on the windscreen and it was 34 Celsius outside on holiday. For example, I could play a game in my home (in the UK where it is currently much cooler) on full brightness and never have any noticeable problem with brightness throttling.

The throttle will only activate if you have the screen brightness at 100%, a quick workaround would be to set the screen brightness to 99%.

Well I guess the issue her is that mine is not a 9005, but a 900A.
So that might have some bearing as I run mine at 100% brightness all the time and at nigh as I am going to bed i play Valkyrie Crusade on the charger and have never seen any flicker or dimming in video brightness.
I just this weekend played NFS: Most Wanted for more than three hours straight with at least 2 hours on the charger and all at full brightness and never saw this. I am sure because I usually use auto brightness but don't like it shifting brightness whilst playing a game and changed it back as soon as I was done. The thermostat in my flat is usually set at 23.
Also like I said, its not like I have never seen the message, just in vastly more strenuous situations than you are describing which again makes me think you have a hardware fault making this problem occur more frequently.
Let's see if someone else can replicate your problem in similar circumstances to see if it is a more widespread issue.

I was using a LG optimus G pro before this one, in my opinion the bright is poor in this phone vs for example S4 or LG. So , will be very interesting get a solution meaby by kernel or similar to get more bright. I offert another 10$ if anyone can developed any thing in this direction.. thanks in advance

I want to start a bounty (if there is even any interest for this?) to disable the screen brightness throttling.
Now of course I understand people say "oh it will damage your phone" but you know what, so will overclocking your processor and graphics etc.
My problem is that whilst not even doing intensive tasks, my screens maximum brightness lowers, apparently due to temperature throttles. It is really frustrating because sometimes the phone does not even feel hot, and I'm not even using the phone intensively.
Even if there is no interest in this, I'd happily pay someone to increase the temperature throttle for brightness reduction.
Many Thanks

Buy the n900 (exynos).. it doesen't have that issue
I've read many threads about this issue and I guess that it persists only on SM-N9005 Snapdragon devices. I live in Greece and in summer when temperatures are really high, the thermal throttling issue becomes really annoying especially when gaming, because thermal throttling affects screen brightness, CPU clocks and GPU clocks too! For those who don't believe this, here's a screenshot of my N9005 when overheated.
maybe this...?
I'm in the US, with a rooted N3, 900t. stock kernal and ROM, and have also experienced the brightness flicker/throttle.
I've noticed it under varying circumstances, but yes, most frequently when plugged in and surfing web.
I have Xposed framework installed, with a CPU temp display module. Based on what I've noiticed, the dim happens around 146-150 degrees farenheit. Most games, however, will not allow the dim to occur.
There is also another Xposed module I have been using with mixed results called DVS disabler. It will randomly keep the screen from dimming at temps as high as 167 degrees farenheit! (at that temp, i can feel the heat coming off the screen at almost an inch away)
Side-thought::: I have a 'tempered glass' screen protector on that may/may not be affecting the whole temperature thing. not certain.
I get this issue too... Sometimes not even doing anything that intensive... Hopefully it's a simple kernel tweak.

Hello everybody,
I opened this thread so anyone experiencing this problem (overheating and lagging in heavy games such as: Real Racing 3, The Amazing Spiderman 2, even Candy Crush, Asphalt 8 and so on) can discuss it here and maybe we'll get a better perspective of the problem, and maybe find a solution for that.
The Problem :
The phone would heat up, sometimes to the point I can't touch the phone, and the game FPS drops significantly (the games start to lag).
It happens for me after about 5-8 min of gameplay.
From a little google search, some users reported that the problem was caused by the constant running of the IndexService(this process is responsible for Indexing files both on the internal and external sd card) process, some users formatted the sdcard and reported that it has stopped, some users reported that the problem is still there, some users replaced the sdcard with another.
For me, I'm still trying to figure out if the sdcard is the problem by running some monitoring apps like System Panel Pro, and waiting for tomorrow to see which process/apps uses the CPU more than the others.
For anyone commenting this post, I would like you to ask to state if you are on a stock or custom rom, as well as the kernel.
Hopefully, we can identify the cause and help the Note 3 community and finally enjoy the full power of our AWESOME phone.
Happy discussion!

From my own experience, the cpu clock and the brightness of the screen has most to do with overheating. I have the same problem on a rootex X-note v13 (and all other xnote versions before 13), the cpu temp would reach 60 degrees celsius after 5-10 ninutes of gameplay on max brightness and stock cpu clock. BUT if I were to lower brightness to minimum and lower the cpu clock to 1.7ghz (left it at 1.7ghz since then out of laziness), it would last at least 25 minutes before reaching the same temperatures. Still, I would be curious if there is any software trigger that creates this overheat, not just the cpu and brightness. I had my phone unrooted for a very short period of time so i cannot really say, but it did feel like stock unrooted did not overheat so fast. Or maybe it was just a placebo, I do not know

Not sure what could cause that problem but i cant confirm that i dont have the problem, i usualy play RR3 and Clash of clans for long periods of time, 2+ hours and my phone wont heat up at all. i do have the lastest RU official firmaware do, but even with the other ones i never got that problem, i use to hate my s4 for that but i cant be happy enoght with my note 3.

I will be sending the device for repairment to see what the problem is, and will report back here
Maybe there is a problem with some Exynos devices ...
Will be interesting to find out what's the cause for the problem with our high-end phone.
Update: installing other ROM + Factory reset in that ROM gave the exact same effect: overheating.
Disabling DVFS completely fixed this issue for me.
Either use the DVFS diabler app or Wanam exposed to do this.
FYI I have the n9005 so this may not work for you.
I think everyone has the hot screen issue but for me it seems to happen in certain games only.
This isn't limited to 4.4.2 either, it happened in 4.3. It really seems to point to a software issue rather than hardware.
The weird thing is its the upper portion that gets hot on my phone while the battery portion is just normal.
I have temperature software on mine and for what it's worth I've never had a warning about overheating yet.

Disabling DVFS does not Solve the problem unfortunately...
The heating is where the cpu is...
It gets to the point I can't touch my phone...
I've tried different games and it kinda happens in every single heavy games... It is very annoying that I have such a powerful phone and I can't fully use it as I please...
Will try to send it to Samsung and see what they will do...

I managed to solve the problem !
Opting out google's location based ads in Google settings , disabling Samsung DVFS , formatting the phone and SD Card (with data included), installing a custom Rom (Dr.ketan K7 ROM with some options from the AROMA installation) ,
All that has managed to solve the problem .
Now the phone just get warm , as I think it should be for such a thin and powerful device.
I hope that now everyone that have the problem can solve it and enjoy his awesome phone!
Have a great day guys!

What CpuTemp is normal while phone is being used?
My temp fluctuates between 35-45 C (95 F -113F) while web browsing, using Tapatalk etc.
Is it something abnormal ?
My top 2 battery drains are Android OS & Android System.
Thanks
Mine overheats aswell especially on YouTube (56 celsius). Few times I discovered the minimum CPU frequency change to 1.5 ghz.

If you have SD card, it might be causing heat and lag issues, so try to remove it then try phone, if yes then format it, if its not the cause then perhaps you have an app causing problem, so do full wipe from recovery mode, after that try phone for couple of days without downloading any app.
The problem was DVFS. SD has nothing to do with battery drain

The temp seems about right.
My phone got up to 80C when I tried to play it once for more than 10 min and then it just did a reboot...
Within the Android OS and Android System services there are a lot of processes going on... You should try and pin point the exact process that causes Android OS and Android System to be active.
I'm here if you need anything else!
