Hello XDA,
Are any of you experiencing overheating and throttling on your Xperia ZL's?
I can't be sure that is happening to me, but recently when in 3D, the phone gets quite warm (normal) but then my 3D games start stuttering badly (sign of throttled CPU or GPU). When i hold the phone in front of the aircon and play, this issue doesn't happen (indicating better cooling / no heat or throttling).
The thing is, this is an issue that has only just started happening as of yesterday, despite nearly 2 weeks straight of 3D gaming on the phone (mostly Dungeon Hunter 4).
I've had some success throttling my CPU myself to 700 mhz, but that is only a temporary solution. The phone simply takes longer to get hot and then the game starts stuttering again. My guess is the Adreno 320 GPU is throttling, and it really doesn't have anything to do with the S4.
Any help would be appreciated.

Hey,
i just bought an HDMI adapter for my GNex and wanted to play Crash Bandicoot with the FPSe Emulator, but the performance is like a wave ^^
For some seconds very smooth and then it begins to lag for some seconds and so on...
I also noticed that the warmer the phone the worse the performance, but why does it even go hot?
i mean the PSX has a 33MHz CPU
My setup: Apex 1.0.2
PopcornKernel 7.2
Does anyone have a simular problem?
cheers
I have the same "issue".
Fpsce works perfect on my Xperia Play, for example with Colin 2, always 50 fps, always perfect.
In Nexus i have over 40 fps with hard downs who makes the game inplayable, even with dual core boost marked.
I don´t understand anything, maybe is about the 720p, maybe ICS, maybe GPU....

so when your phone gets warmer it has lower performance?
its probably due to throttling due to high thermal output. regardless of governor, kernel, or settings, if the chip gets too hot it will throttle down to the lowest state, usually 350mhz. causing massive lag. this is normal practice in a lot of poorly cooled, space confined chips. maybe try undervolting to keep the temps down. stay away from overclocks. they are not stable due to this reason. i rather play smooth 30fps then 50fps with constant stutters and freezes. overclocking does not solve all issues, it usually introduces new performance issues due to bottlenecking

okay i will try, but why does the CPU even get this hot while emulating? even my calculator has more power than the good old PSX
Because it have to convert it to a higher resolution + the emulator might not be that good...

OK, someone is willingly to sell me a Tab Pro 8.4 for a good price. Now everything works well, except for small fly in the ointment. He said while heavy gaming sometimes the tablet reboots. SO not sure if this is a software or hardware issue?
I have personally never had this problem, nor have I ever heard of other people getting this problem. The 8.4 can get pretty hot on the left side in the middle, where I assume the processor is located, though. Seems like a hardware problem specific to that tablet though, maybe a bad batch of CPU's.

Nor have I, seller says everything works just really heavy gaming that its rebooted at times.
Shouldn't reboot, the tablet has thermal monitoring and will down-clock the cpu if it gets too hot, it could be a software issue or a problem with knox as that is known to reboot the tablet...
maybe it was a return and someone installed a custom firmware then flashed it back to stock.
Though can't really rule out the possibility of a buggy game, some apps such as reicast will cause this tablet to reboot due to a kernel bug / snapdragon bug (on stock firmware).
I have tab 8.4 and it heats fast when I play some racing or 3D games (example Asphalt 8, NFS:MW,Roblox,Minecraft,etc) or even if I watch YouTube videos on 1080p60 or 4K for about 10mins. And when it overheats, performance is worse than not overheated(on YouTube, not a big effect). That thing is only when I play that game or watch that video. Can I somehow make it not overheat without losing performance?

if you are rooted you can downclock the cpu or limit the number of cores active at one time.
Turning the screen brightness down can help too.
I am NOT rooted, brightness is about 20%.
Poking around with the kernel, and experiencing this myself, the cores are pretty hefty and can generate some heat under full power. The GPU is not so hefty, so can generate heat when overworked (e.g., by playing games). It underclocks itself to protect against overheating, but of it gets to a certain temperature, it will restart to remove the load on the cores and stop the generation of heat. There is nothing adversely wrong with your device. That's supposed to happen. Trust me. I have had the Tab Pro for a while.
Hi,
I recently got an LG G3 and tried every single tweaks to make the gaming performance a little more enjoyable but it's plagued with low framerate with everything I throw at it. I tried to play Dead Trigger 2 (which is not very demanding) on high settings and it's unbearable. Same thing with Modern Combat 5: Blackout. Anyone else out there experiencing similar issues ?
Hi! I guess the phone gets too hot so the SoC throttles down. Try to underclock a little bit because even if you run at lower Mhz you may get better results due to lower heat production and therethrough less throttling.

Hey Guys,
i have a problem with my Nexus 5X since weeks and now I think I have founded the problem. On daily usage, in games or in Benchmarks: the two big Cores are always stopped. Bit I don't know why. I have tested it with some Games, Geekbench and CPU-Z. Can anyone help me?
Thanks

The thermal throttle stops the big cores when they reach a certain temperature. It's "normal" behavior on this cpu.
But they are stopped all time. When I Power on the device and start a big game, when I wake up the device after a while and play a big game... ever! Temperatures are round about 55°C
If you're on one of the Android N Dev Previews then it is probably the well known bug that shuts the big cores off. If you're on Marshmallow then it is most likely thermal throttling. I think the big cores turn off at about 45C.
Okay. But why does my device heat up so fast? I have read a few Tests and the Processor never gets hotter then 42°C.

It's your use mostlikely, e.g. camera (, cpu intensive games, benchmarks etc) takes all the cpu power possible, that'll heat up your device into range of thermal throttling in no time, while one can browser normal websides for hours without any signifcant heat building up.

I think it's a general misunderstanding of how a big.little cluster cpu works. Those aren't 6 equal cores, the big ones are (most of the time) just there for short term boosts and otherwise drag down performance overall, especially when the cpu heats up. I can see a much higher use of the big cores e.g. when loading websides compared to gaming, where it comes down to how the game can run on the remaining cores (little ones) after a few minutes.
But the Cores shouldn't heat up after a few seconds, should they? And they are simply alsways off.
I have tested it with the Geekbench 3, Smash Hit and the Camera App. The results like the temperature and the clock Speed came from CPU-Z.
My Standard result of the Geekbench is 650 and 2500 points. The two big Cores are stopped and the temperature is round about 50°C
The Standard witch I have found in the Internet was 1300 and 3600 points. The temperature shoult be round about 42°C-44°C
Phone is mostly around 38C, it clocks down to 1689mhz while gaming, tested it when it was 25C and dropped to 1689mhz, so no thermal throttling. If im not playing a game while the phone is 38C it stays 2016mhz. Device is Redmi Note 4x rooted. Changing the governers does absolutely nothing. I tried hill climb racing and it was fine. Is this power limit throttling(A task is too strong for the cpu, if cpu cant go above its tdp limit it clocks down. Happens on my laptop, havent been able to increase the limit)? I cant find anything about something like this on android. What could be the problem?
