[Q] Malfunctioning Device? Internal Damage?

Well, to sum things up, my phone has never been so slow and laggy ever since flashing Faux's ultimate kernel (v0.0.6u). (Not blaming anyone other than myself, just sayin)... Anyway, I have the feeling something internal went horribly wrong. Seeing that no other kernel other than Faux's ultimate had GPU turbo boost @ 320/220Mhz, I thought it would be nice to try it out with BeastMod 4.2. After using OC Daemon to set my CPU gov to ONDEMAND and stock clock speeds, I did the usual and tested the rom throughout the day. Battery live was insanely awful. The phone seemed to draining at a rate comparable to using YouTube on 4G, EVEN WHEN THE SCREEN WAS OFF!. Oh, and it got pretty warm, not hot, but noticeably warmer than usual. Knowing I would not be able to flash a new rom/kernel till later that day, I simply shut my phone off for the time being. When I got home, I discovered the problem. Even after switching back to... let's say Bullet w/ Juggernaut, I noticed that scrolling through anything, playing a game, running a benchmark (especially this one), caused the phone to slow down, hiccup, pause, lag, whatever you want to call it. In Quadrant, the fps for the 2d test was hitting high 20's before, and now, it jumps about the teens goes as low as 8fps. Score: 1801...2130... Am I running a dual core? Not anymore it seems... Feels like the second I touch my phone, thermal protection kicks in or something else is choking it and preventing my phone from being smooth like it used to be. Even tried underclocking to sensation speeds (1188). No help at all. Still craps out on me. I'm beginning to think I fried something inside. Broken Adreno? Hope not... Any ideas?
Note: Yes, I followed all ROM and kernel flashing procedures. I may be a noob (literally), but I do know how to flash properly.

Maybe try a factory reset and Odin back to stock to start from scratch.

I'll give it a shot. Hoping Christmas Eve is lucky this year.

galaxy nexus cpu throttling on jelly bean?

hi there i got a used galaxy nexus from someone and installed android me 4.1.1 (version 1.6)
now my problem is, when playing intense graphic games (GTA III or dead trigger) i notice the fps drop and rise in the game.
At first I thought the game itself was lagging due to too much happening on screen (such as more characters) but it was not the case.
The game would be silky smooth for 10 seconds then choppy fps for the next 30 seconds... rise and repeat..
it seems the cpu keeps underclocking/overclocking itself... i even tried force closing all my apps before running the game and it helped with the fps a bit but the throttling is still there....
anyone had any similar issues and knows how to fix it?
edit: forgot to add, does your phone get really hot behind the LED FLASH when gaming? Mine gets really hot even on the screen too (On that side of the phone away from the battery)

Stock rom? custom rom?

sorry its custom rom (android me version 1.6 july 29th)
although i briefly remember this happening on the stock rom too so I don't think its a rom issue...
hard to say i can't post in the developer section yet... so i guess here to find out if people are having issues with the stock?
stock kernel if that makes a difference

Wow am I the only one with these symptoms? Hot screen and lagging frame rates? Since no one is replying maybe my CPU has cooling problems? Bit there is no fan haha

Any news about your problem? I have the same problem with jelly beans stock. Playing the game agent dash when the nexus is cold is fine when it is warm slows down, like a drop performance. How did you solve it? excuse my English

Try putting the graphics for the game on low

same problem also there are many persons with this problem.I'm on stock 4.1.1

If the CPU runs hot ( > 64 degrees Celsius), thermal throttling will kick in by reducing CPU clock speed. Works as designed.

You're not the only one who faces this problem - I face it on the stock ROM. The only way to alleviate this issue (not entirely, but to quite an extent) is to overclock your GPU - which means using another kernel that's clocked at 384mhz... which, for me, seems to break VPN (at least it breaks it on Air Kernel - Faux works for a while, then stalls... I don't know the nitty gritty, but that's what seems to happen - YMMV).
I had a thought: what if we enabled GPU acceleration in the developer options and then played it - do you think that'll make a difference? It does, generally speaking, make a difference to the other programs (apart from breaking some )

[Q] Decent CPU Temp (Heavy Load) For Nexus 7 2013 with Root & Stock 4.4

Hello everyone! I am very, very happy because i bought a Nexus 7 2013 a week ago. That same night I got home from the shop I knew it was getting root permissions. So i did the rooting method with WugFreshes toolkit and it worked like a dream I must admit. TWRP and Superuser installed in a flash.
After root permissions the fun started - Custom Rom's, Mods, Tweaks you name it. I am currently using Stock Kitkat 4.4 ROM with many tweaks:
PureGraphic HD
PurePeformances
AwesomeBeats
PureAudio
I have the Franco Kernel and it's great. I have had no issues what so ever so far. It's smooth, fast and responsive. Games run extraordinary fast, I can amp up the graphics without to much frame drops, this includes games like GTA SA, GTA VC, Modern Combat 4 and N64/PS1 Emulators (and yes i own the roms :highfive. Back to the Kernel. All Wireless adapters are working (bluetooth, wifi, nfc etc), and wifi seems faster. Battery doesn't drain very fast at all, even with intensive load. But here is where my question actually is ...
I do understand that this question has been answered somewhere else in the Nexus 7 2013 forum, however can someone tell me my question in more detail? Thanks. :good:
Q. My question is, between what cpu temperatures is safe for my nexus 7 2013 to play intensive games at (etc emualtors, gta series, MC4)? What temperatures should i be alerted at. I am currently running GTA Sandreas and emulators at around 50-65 Degrese celcius (yes that's right celcius us auzzies use the metric system :silly: . )
Also if i overclocked it to 1.7GHZ then what would a stable temp be while idling and heavy load? (thanks!)
(last minute edit... Also what CPU is really used in this? People say it's an undercloked s4 pro or something? So if overcloked back to 1.7GHZ it'll be fine? Right?...)
Other information consist of:
.All the mods i said i have, stated earlier
.Franco Kernal
.Wireless devices faster tweaks
.Use 4x MSSA
.Warn at 65 Degrees Celcius
.Other small mods i can not think of...
.Stock GPU & CPU clock speeds
If anyone can ask my question A.S.A.P it would be greatly appreciated, i am currently new to XDA but not the the Android OS. And to all of you whom think Android is a terrible OS go get one of the most biggest fails since Apple Newton the iPad.
P.S The XDA forums is great, and everyone on here deserves a good old beer. If this thread violates any T&C please go right ahead and delete it. Thanks so much,

How come nobody has said nothing to this question?
Btw, my cpu hit 91º C this morning while I was playing nova 3 and I was using an overlay to see my gpu frequencies and usage. I think is too much.

I personally wouldn't worry about cpu temp that much. All the developers of custom kernels will set the thermal limits to whatever they think is appropriate. A much bigger concern than the cpu temp is heat being conducted to the battery. I would make a point of keeping the battery below 120F and I personally don't want to see over 110F (around 45C).

The overlay thing I was talking about earlier was the cause for that cpu temp, it used like 2 entire cores to function, without it, temps are more stable, can you believe that the tablet actually kinda burned my fingers if I pressed too hard? That's insane.
Now, I understand that the battery's temperature is something important, so you don't ruin your battery lifespan, but how come cpu temps don't matter as much as battery's does? What's the max temp for these devices?

I'm going to "guess" and say somewhere around 100C for the cpu. Just a guess. 60C for the battery would absolutely be bad news. 50C would make me nervous. Also the cpu will start to get throttled (underclocked) once it gets up to a certain temp, And once it reaches the max temp the cpu will get shut down and you will have to wait for it to cool down before it will boot back up. I would worry about the heat affecting the motherboard and the components on that before I would worry about heat damaging the cpu.

Theorically speaking, the safe working temperatures would be the where the thermal limit is which is around 105ºC.
However, it doesn't work like this because heat spreads to other components and more importantly, it spreads to the battery and we all know batteries don't like hot temperatures since it drastically reduces their life span and charge capability.
On practice, I would say keeping your CPU below 70ºC which will result in a colder battery aswell is the sweet spot.
On the Overclock matter, I have mine at 1900'ish Mhz and my GPU is at 490'ish Mhz and I haven't experienced any abnormal temperatures while runing benchmarks. Infact, the temps were kept below 50ºC which is more than fine.

I think the battery burns like hell when you're playing and charging it at the same time, am I right? I wonder, if the cpu and gpu are underload, the battery will drain quickly, does this mean that this produces more heat to the battery? How does that work.

[Q] Just a few questions about The Tab Pro 8.4 (SM-T320)

So I just reinstalled Cyanogenmod after a few tweaks I didn't like - Basically decided I just wanted to start fresh.
I booted up into TWRP, and clicked Wipe > Advanced Wipe > Checked Cache and Dalvik Cache, and wiped it.
Then proceeded to install my CM Mod zip file, followed by Gapps.
Well after it installed and booted up, It crashed and rebooted by itself. Now it's very hot in my room, which i'm sure plays a factor.
So I underclocked to about 1067ghz to be safe.
Im not sure what is going on, but using Cpuz or whatever that app is to monitor the temperature, almost all of the things that show up under the Thermal tab are around 40 celsius. Im wondering, is this normal? It definitely should not be that hot, especially underclocked, right?
Just looking for some answers, and possibly solutions.
Thanks in advance, guys.
Ps, I might post some random posts after this one to get my damn post count to 10 so I can actually start using these forums efficiently. I hate the way it is set up where I can't comment on other threads until I hit 10 posts, and my replies get sent to some random ass forum that nobody looks at lol. Plus I have to wait 4 minutes in between each, which means it will take at least 40 minutes to just actually get up and running on here, lol. You guys should use a different method for human verification, especially since I registered my email.

40c seems about right at 1Ghz and if its hot out, I checked mine but it's cold here and cpu is at 300 mhz (idle speed) and I am at 34C-ish (stock firmwmare)

Thank you, but do you have any ideas as to why I get random rebooting? It kinda scares me, I hope nothing is wrong with my tablet. Do you think it could be something incompatible or whatnot?

Okay now it is up in the 50s and I have no idea why. Nothing is really running that intensive. I think that's why it keeps rebooting, from overheating. What could possibly be going on?

It could be overheating does the tab feel hot to the touch?
even so the CPU should be operated by a governor (usually interactive or on demand) so when it's idle, it's supposed to turn off unused cores, and throttle back the cpu0 to 300~ mhz , and then increase the mhz or active core(s) depending on system load (the GPU does this too from 200mhz to 400 mhz), the CPU is not supposed to operate at full speed all the time if it is you either have a rouge app forcing the cpu to do lots of work or something else going on..
Other then that I have always only run the stock firmware in my tablet (to keep knox at 0) so it might be something wrong with CM build you are running

Someone help me please!

OK I'm new here and just made an account because I've been up for three days trying to figure out what's wrong with my phone. I have a LG G3 D855 and I've rooted it and flashed recovery (twrp) and two different kernels and a custom ROM(XenonHD) and I just can't seem to get my phone to not reboot while running antutu benchmark or really doing anything else for that matter. I've installed 777kernel and I use Lionheart and zen and I have it oc'd to 2.8 and the GPU to its max as well. Here's the thing though, I can play games (dead trigger 2 and unkilled) without it shutting off but doing other things it'll shut off randomly and it drives me nuts. Sorry if this is long but damn I just want to game until my thumbs bleed, without lag. I appreciate all the hard work you guys do here so I hope I don't sound like a fool. Also I'm running xenonhd right now and I have my daily one that's stock 5.0 v20i sea xx and that one does the same thing just with navel kernel. I don't care about battery life. I just want to be able to enjoy my games smooth and not have my phone shut off when browsing the internet. Btw its not heat related because I've been testing it. The games get up to like 90C and it doesn't shut off but chilling at 60C it will. Doesn't make sense. Sorry for long post..

Run it at stock frequency, or 2.6 max. That's too high in my opinion. And it can be rom/kernel related so i suggest installing a stock rom.

So i should clock it down? Can i keep the gpu turned high?
