I'm on the verge of returning my G Flex 2. Maybe someone can convince me otherwise. It's missing features that OG Flex had, the battery is short lived, the processor heats up. Check this out:
http://www.androidauthority.com/snapdragon-808-vs-810-overheating-test-605273/
The throttling is unreal. Not only that, but the tests just weren't on the 810, it was on the G Flex 2.
Well the overheating is real, but I don't feel it in performance. I play a lot of games and although the phone heats up everything is running on stable 50fps. My oneplus one never went above 35 fps on the same games and heated up as well.

This phone doesn't seem to get nearly as warm as my nexus 6 did. I also do not have any system lag but I don't play many graphic intensive games. I did run antutu 5 times in a row to try to get it to heat I'll but it still didn't get that warm. What games are you playing that really gets it hot?
Sent from my LG-H950 using XDA Premium HD app
I play world of tanks which is rally demanding for the processor. I discovered that the overheating comes from tasks related to radios. See my post in the v10e update thread.

I play Hearthstone a lot. I also play CoC, Boss Monster, Subway Surfers, Smash Hit, Osmos, handheld emulators, Minecraft PE, etc. So basically all medium-intensive games. The device gets pretty damn warm on all of those games and drains the battery at 1% every 1 minute. It even lags occasionally. But, you're right, FPS doesn't seem to be affected too much.
But my problem is that even when it's not games, it still gets hot. Just watching netflix or youtube videos this thing gets warm. That's kind of sad. Maps and other data intensive apps will also heat it up.
Idk, I'm having a real tough time deciding on returning. It's got a higher resolution, a more manageable size/weight, and better looking software. But at the same time, it has a throttled CPU that heats up, a smaller battery + more battery drain, and what looks to be no support for any modding (no custom recovery, no back-to-stock method(for H950), no xposed (that might come later), and no ROMs). The forums just aren't thriving like the first Flex did.
There's other smaller factors, but battery and CPU are big factors for me...
For me the software update solved most of the basic overheating. But yes you are right this is not an ideal setup at the moment. Perhaps you are better off with a 2014 flagship.

And maybe I should wait for that software update. Because I'm still on 5.0.1. Is it supposed to get 5.1?

I heard nothing regarding 5.1 but it should be fine N the pipeline for a 2 months old phone.
But sadly you newer know how it goes with LG
Yes. It is supposed to get 5.1... Updates will fall in order of phone age. G4 to G Flex 2, then the G3 and finally the G2

just curious lol I love to push my devices to the limit!
I'm pretty sure a 50% increase in CPU speed on a dual core processor is more than enough for this guy. Why would you even need to go higher? You'll just end up breaking your device and come here complaining to the devs that it's their fault..

I had mine set to 1.5 and it was very smooth and fast. But I noticed that if I was watching a movie, my xoom got pretty hot in my hand. Maybe not such a good idea to go that high or much higher than that perhaps?

Exactly. Same here!
i think if it was totally safe motorola would have been the one to do it and brag that they have the fastest tablet in the market with a 1.5 - 2.0 Ghz Processor. if you want you device to last, leave it with the stock speed, this thing is pretty fast as is, and if you do have to overclock i think the max would be what others have said 1.5. there is no other benefit, and i doubt you will notice any difference. other then your battery lasting 2 hours and your web pages loading a second faster (not important), and maybe apps opening a little faster(won't notice) and then your device getting hot as other have said, which can bcome an issue with other things on the the motherboard becoming hot. and in the next few months you'll end up with a Motorola DOOM
Hey everyone!
Sorry if I do or say something wrong or in a wrong place, as this is my first post here and I really need your help.
I have just received my Nexus 5. I was loving it so far, but I have recently noticed a weird problem - the youtube videos in HD were really choppy. That is when I have decided to get AnTuTu and test my device with it. 23k!? That is barely more than Galaxy Note 2. Something is definitely wrong with my device and I can't seem to find what. Please help!
I don't see a problem here.

Is it supposed to score that low? I may be missing something, but shouldn't it score higher than SGS3?
And what about the jerkiness of the videos on youtube?

mine score around 22k, and work awesome
I did 3 runs of Antutu.
Run #1 22k
Run #2 29k
Run #3 26k
Just ran it again after making sure every app was closed, 29k.
Hit your multi task button and swipe close every app then try it.
No idea why its random.
YouTube is buttery smooth here. I don't see how it's normal if it's choppy on one of the fastest CPU. I would try a factory reset.
Most people including me have noticed good performance in everyday usage, but poor results with benchmark such as Antutu.
My investigation involved monitoring soc (cpu) temperature and clock frequencies.
I observed that the standard kernel that comes with Kit Kat has thermal management that aggressively throttles CPU clock frequencies when the temperature exceeds 63°C.
This will cause the clock frequencies to be reduced in an attempt to lower temperatures. With a benchmark like Antutu that causes all four CPU cores to be heavily loaded and run initially at maximum clock rate of 2265 MHz this will lead to clock frequencies dropping as far as 1100 MHz occasionally, with substantial drop in performance.
I have been unable to determine if the Adreno 330 is also subjected to similar thermal throttling.
Custom kernel will provide the way to overcome this for those willing to modify.
The highest Antutu score I've seen on their website is 30000, which is some way below other Snapdragon 800 powered phones, and most scores are below 25000, which can be bettered BT Snapdragon 600

Thank you for your responses. I am not the only one then.
But I would still like to find out what exactly is wrong with youtube. Every video's choppy, there's a lot of stuttering and frame skipping. Launching videos from Chrome feels better, but not much.

Don't forget the recently documented "optimizations" that most manufacturers are building into their devices. Benchmarks are beginning to mean less and less as manufacturers have discovered their use in marketing.

Yeah, I get that.
But mine still performs horribly in videos. I have just done the factory reset - to no avail. Youtube is completely unwatchable. I have tried to plug the charger in (just to rule out some weird power-saving issue) - same problem. Haven't tried to launch a video from the device itself yet though. I have also tried Real Racing 3 just to test the performance, and I guess it's OK. It's not prfect, as I can feel some framerate drops, but it is nowhere near as bad as the Youtube jerkiness.
No idea what's going on. Seems like no one else is having such a problem. Probably gonna have to return the device.
I generally get great battery life using regular apps throughout the day. But many games seems to eat up battery life quicker than I would have thought. That coupled with how hot my phone gets, I'm a little worried there may be an issue with my phone.
The two games where my phone feels like it is burning up are Plants vs Zombies 2 and Anomaly 2. After playing a session, a quick look at the battery graph shows an extremely steep drop.
Is this normal? Maybe it is, but it doesn't feel or seem right.

its normal. cpu and gpu intensive games will warm up your device to a toasty level. but that why they make the phone have a thermal throttle. when it hits a certain temp, you phone will automatically reduce the cpu speed to cool down a little. but the heat from gpu/cpu intensive games is more than normal, its expected. btw, the safety shutdown temp for the n5 is 100C, which youll never reach because of the thermal throttle, only if you have root and disable thermal throttle, then it could hit the safety shutdown temp
I know about the problem with Plants vs Zombies 2, it eats through battery like crazy. I don't think that there is an issue with your phone, because your battery doesn't drop like that at any other intensive game, does it?

I've noticed the exact same thing with PvZ 2. It's addictive as all hell, but chews through my battery.
I really wish they would release it on the Amazon Appstore so I could put it on my Kindle Fire. Unfortunately, because of the Google Play integration you can't even sideload it to a Kindle, you just get a black screen when you try to launch it.

I don't play any intensive games actually and I wouldn't even catagorize PvZ2 as intensive. Maybe it is just suboptimally coded apps. Anomaly2 isn't even really that intensive. Not like a FPS/3D game anyway.

PvZ2 is terrible. Get Franco kernel + his updater app. Set the per app mode of PvZ @ 652MHz. Still runs fine. The only difference you will notice is when the last big wave hits, there can be a little slow down, but it goes away quickly. With all 4 cores running at 652MHz, there is virtually no heat. Will get you 1+ hour more game time. I'm experimenting with underclocking the GPU for it as well. I don't want to underclock the phone when I'm just using apps, but these games are using much more power than they need to be using. 4x, at least.
I think it's poor coding, as @flintdragon suggested.
Hello guys!
I recently switched to this phone..
So my question is that whether it is my nexus 5 which heats up even after using it a little bit or anyone else is also having the same problem??????
Sent from my Nexus 5 using XDA Premium 4 mobile app
To be honests, for me, the only way to get it noticebly hot is play Real Racing 3, Asphalt 8 or other heavy games.
Oh and using it for browsing, calls, facebook etc wile on charge heats it up too.
According my opinion its ( feels ) much cooler than N4, i had before.
U have any case/bumper ?
Can u also mention heat in degrees?
The Nexus 5 definitely runs much cooler overall than the Nexus 4. These devices with their processors are made to heat up in an intense situation such as gaming. The device has an individual heat sync to soak that up and release it once the processing you've initiated has been lowered. Heating up is normal. The device will know when it's too hot to function, but that would take a lot to happen.
Slight warmth is nothing to be concerned about when browsing, or on a call. You should be concerned if there is no heat and you're playing a game for a few minutes or more.
Odds are high, your battery will die before the heat to the processor damages the phone. If you're finding it's difficult to hold the device because it's hot on your hands, I'd suggest setting it on a flat surface or get yourself a snug case. Mind you, a case will concentrate the heat and could potentially make it worse.
See this is called heat, my screen and fingers were literally burning

There is some sought of problem with my device, thermal throttling doesn't turn on when using stock kernel
Its dead trigger 2
88C???
I think its too high indeed, although i dont play games.
Again, do u use any kind of "close type" case?
Sock kernel yes, but any kind of custom ROM with any modified system files ( build.prop etc ) ?
So I finally decided to root my G Flex 2. I've been talking about disabling cores for a while. Thought it may help the thermal throttling issues. Once I rooted the device I downloaded "Multicore CPU" and started disabling cores in a couple different combos. I've finally settled on disabling cores 4 and 7. Since I disabled the two cores heat has not been an issue and cores 5 and 6 are running at 2ghz. Reduced lag, and benchmarks have shot up some. Personally enjoying the lagless environment. Figured I'd post my experience with this. I'm hoping overall battery life will be better as well. Won't know for a day or two though. Oh and it stays cool while charging and in use. It used to get really hot before.
Anyone else have any experience with this?
So here are results of disabling cores and thermal throttling or lack there of now.
I also want to note that my benchmark scores were lower than the note 4 after some updates until now

Ok on YouTube mine gets a bit warm but not as hot as in Chrome (on normal sites, nothing fancy). Watched twitch in Full hd for an Hour yesterday without any heat...seems like some Apps are better optimised for the sd810 than others
Are we getting a sd808 by disabling 2 Cores?

I am also coming from oneplus, I must say you are sadly right. Newer is not necessary better in this case.
I hope with some optimalization this can be a Ferrari.
I was already let down by LG a few years before, let's hope it is not the case now.

I have the AT&T version of this phone and for me cores 4,5,6 and 7 are always on except when the cpu goes above 36C then cores 4 and 7 automatically get disabled. I'm also not experiencing any lag and it's actually very smooth and fast. It also doesn't get very hot unless I run Antutu benchmark like three times in a row. What kind of CPU temperatures are you guys seeing when your phone gets hot?
