Phone getting too hot = GPU slowing down

Hi everyone
this is my first android phone and I'm facing quite an unfamiliar problem because I don't see a lot of people posting about it but the ones that do wonder what's the cause of it
First I started with Rocket Rom and abyss kernel, I noticed that my phone gets really laggy after 5 minutes playing games and keeps lagging when exiting them, antutu graphics benchmarks are always capped to 30fps if I run a complete test, so I changed to CF-root and my problem was gone, but still I wanted a tweaked custom kernel so I tried FM and after a while a got the same problem again, so I figured out it was a temperature problem and went back to CF-root.
Yesterday after almost one hour playing it happened on CF-root too, so I get really pissed off because I have a device that I SHOULD be able to game on, and I can't do it for a reasonable period of time due to heating, on abyss kernel in less than 5 minutes I would experience that in a game (that's why I could never run an antutu full test, the first cpu tests heated it up too much already), FM was better but still, I guess I played 30 minutes before it slowed down, and with CF-root I was already upset because it is not nearly as fast the abyss and FM but it was ok... for just 1 hour!
so presuming this is a general problem, what do you guys do when that happens, or what would you advice me to do? underclock to 1ghz?
Also, I don't think everyone's device heats up as quick as mine, so should I classify my note as defective?

That's happened to me on two phones htc incredible and wildfire s, try going back to stock with the stock kernel if that helps. If it doesn't then you may have a defective model.

Have you tried rebooting a couple times after getting everything setup? My Note seems to be doing a similar thing, last night after flashing Rocket Rom with abyss kernel for the first time just using market, browsing, etc while setting everything back up my phone was getting really warm and even just browsing the app drawer was slowing way down. I've since rebooted a bunch of times and it seems to be better, but it's still getting warm

I'm just learning about tegrak stuff right now, his app has a lock gpu 267 option, dual core always active, I think I'm going to downclock to 1.2 and try those options.
Also I will reboot a couple of times, I don't know if the correct way is to just reboot twice or everytime after flashing reboot twice wiping caches and stuff (full wipe? twice?)

Two changes improved my s3 (root)

Hi guys, I just wanted to share with you two changes that improved my Samsung s3 i9300 (Android 4.3 stock-rooted). My friend has the same phone and had the same results. I hope it's useful to someone:
1 - FastDormancy disabled.
My operator doesn't use it, so it causes over-warming and battery drain. If your operators use it you don't need to do this.
More info: http://www.xda-developers.com/xda-t...ur-battery-from-3g-drainage-xda-developer-tv/
2 - ZRam disabled
This change fixes battery drain too and it reduces significantly the lag when you turn on the screen. I sometimes had until 30 seconds after I pressed the bottom. Now it's 2 secs. Not as fast as some phones of the same price but is way better than the 30 secs I had (It made me lose lots of calls).
Just changing this It changed 360 degrees my user-experience. Now my battery lasts twice the time and I don't have the problems I mentioned before.

Agree with the fastdormancy, I think am getting around 40 minutes extra screen time with this disabled. ..but how to disable zram?
Sent from my GT-N7100 using Tapatalk

Well, zram was implemented for a reason. If you disable it, expect crap multitasking. A lot worse on a samsung rom. Been using it for a long time now, I do notice some slight lag that wasn't there with zram disabled but never had anything that severe. Don't even think I've waited 30 seconds for anything lagging ever. Something is definitely wrong with your phone. That said, my phone could not cope with z ram's inicial implementations, would even randomly hang and reboot. Very different since I changed for archi's rooms a good while back.
Nowadays, what i gain with zram more than makes up for what slight lag I get, imo.
Fast dormancy is something I have disabled for the sake of it. I have no clue if my operator uses it but I tried on an off and seems to make no difference whatsoever in my case.

I had 30 sometimes, not all the time. Mostly with save battery option activated, wich save battery but left the phone slow. With zram disabled battery last longer and the phone is not slow. Maybe a little with multitasking but it last twice the time. It can be enabled or disabled as easy as save battery and have better results.

I'll try playing with zram and see what the results are for battery/performance

It's not true. I set zram to 150MB and it improves multitasking as well, no slow downs or something at all.

Nexus 6 boot up time slower than rivals?

Please tell me this isnt true..
Nexus 6 vs Note 4 vs LG G3 vs Droid Turbo boot ra…: http://youtu.be/HkGB7jTnT_Q
I know this is an encryption issue most likely but you can't switch it off on an nexus 6. You can on other devices including a nexus 5 on lollipop

Why should that even be a problem? I turn my nexus off at least once a week for the night to let it sit, but still. I don't understand why this is a huge concern.

Ok, it's not true.
Pretty obvious it's the encryption though.

As long as boot up doesn't take as long as the Blackberry's did back in the day...this is absolutely irrelevant to real world usage.

Thanks for bringing back that horrible memory

I don't know why folks are saying this is irrelevant. This is a premium phone afterall. I switch my phone on and off several times a day when the battery goes.

Well the note 4 still runs Dalvik only, turbo probably has Dalvik by default... This makes total sense as your phone boots up slower with ART to help with performance later.

The N6 has to be decrypted while the others don't because they're not running Lollipop. Wait till they have Lollipop.

It's 2014.

I reboot about once a week on average, usually right before going to be. Boot times are meaningless to me.
Decryption and ART take time to complete.

I also don't really care that much how long it takes my phone to boot. However, it's still concerning to see it boot SO much slower than its similarly spec'd contemporaries. The slow boot is a symptom of an underlying issue, not a problem in itself.

I don't quite see how this has turned around to me being the problem. I don't have access to power and the best I can get is 2-3 hours screen time.
People need to consider that the way they use a phone might be different to other users.

The underlying issue is that all these devices are not running under the same conditions. Turn on encryption and update to lollipop (or turn on Art) and run the test.

FYI, turning your phone on and off actually drains the battery faster. When booting up, it needs to load like a hundred of process so eventually it will easily eats up your phone's resource. If you leave your phone on standby, it will last longer. 2nd, why bother getting a phone if you don't keep it on for calls. You'll be better off getting a small size tablet and use Google Hangout to make your call for free when needed

Until these are all running Lollipop as well, I couldn't really care less about comparisons.
Even then, who cares if it's 45 seconds slower? I'd argue that the amount of people that reboot their phones multiple times daily are a VERY small minority. On average, I reboot my Moto X once a week or so just to keep it fresh.

Why does my galaxy s7 edge lag after reboot?

T his is something I have been dealing with for 3 months and I'm fed up...
About once every week or two, I turn off my device for a few hours to give it a rest. However, every... single... time I power on or reboot my device, my phone greats me with SIGNIFICANT amounts of lag just after boot.
Eventually in a few hours everything runs smooth, but when I boot or reboot my device will lag behind nearly 500 to 3000 milliseconds.
Just now I pressed my power key and it took my phone nearly 10 whole seconds to turn off or react to any hardware keys. And I'm just coming off smart switch so I have no installed apps. So I'm as clean as stock, but I've still had issues like this since day1
Does anyone hear have any earthly idea why my s7 lags for hours if I reboot/boot?

What kind of SD card do you have? I used an old one when I got the S7 and it lagged horribly, overheated etc. As soon as I took it out it was better.

Samsung Evo 64GB, Read 30MB/s, write 18MB/s. Its nothing fancy but it is just a tier above standard Class 10 speed. It shouldn't be a hindrance to my performance.

Try clearing the system cache?

The cache thing may work. It also has to do with how many apps run at startup and how much ram those apps use. In my experience, that has the biggest effect.

Random lag is starting to piss me off..

so, it seems that whenever I'm out, my phone is slow as all hell. I'm at the store yesterday, and i pull my phone out of my pocket to take a picture of something for future reference. I hit down volume twice to launch camera... so it takes about 8 seconds just for the screen to pop on, and another 8 or so seconds before I can actually click the shutter to take a shot. so, that's annoying. but then, I wanted to Google search something while I was there, so the phones already awake mind you, so i hit home, open Google, this takes another like 7 seconds, and then going to type in the box takes another 5 for swiftkey to even pop up.
I don't understand. it's like, when I'm not home, my phone gets laggy as hell. when the phones plugged in, it gets laggy as hell. now I'm coming from an s7, aka a lag machine, but this thing is starting to annoy me to the point where I'm ready to throw it.
I've recently even factory reset and started fresh and it still happens. it's as if when you wake the phone, doze is just taking forever to ramp the processor speed back up. it's like it's limited to a low speed so there's tons of lag. when I'm using the phone for a while it's fine, but that experience seriously made me want to whip this phone at the ground.
so now it's like, i don't want samsung bc of lag, i'm starting to not want LG because of lag. who the hell else makes a decent android phone now that's actually fast!?

doze sucks. honestly, I get no better battery life now than I did on my note 4 running what, lollipop, and the same size battery. they didn't have doze back then, and it ran better. doze was such a bad programming decision bc it does absolutely nothing for battery, and just makes the phone slow as hell whenever you wake it.
Sent from my LG-US996 using Tapatalk

Same thing here. My battery life is so BAD, yesterday not doing anything but standby and checking a few things, 10m 37 sec screen on time, 7+ hours off charge from 100%, it was at 21%. Lags like crazy from time to time. When, it gets like this I pull the battery for about 5-10 minutes and it seems to work fine for awhile. One other thing that has happened, is my data signal sucks, which is probably the cause for the extensive battery drain. I put in new SIM card, no change. I have seen where others are experiencing the same thing. It was a good phone, until about 2 months ago and all this has started, very frustrating. Note 8 can't get here fast enough.

If you guys aren't getting better battery during standby then you guys have a problem like a rogue app or conflict cause standby drain on this phone is nigh non-existent compared to older phones like note 4. Usage when screen is on is pretty much identical to older phones though.
In relation to topic I do get random lag sometimes which does annoy me but my brother gets random lag on his stock unrooted Nexus 6p as well and id be willing to bet that the high and mighty note 8 is going to suffer from random lag as well.
Just depends on how often you are experiencing this lag. It happens pretty rarely for me and usually only when is really hot out.

the other day at my new job the phone drained like crazy just idling in the drawer. like 30 percent from 7am to 1230pm. it was awful. I noticed my signal was super low in gsam during that time though, which sucks. not sure what I'm gonna do about that.

I bought this phone after changing over from Verizon to T-Mobile. My note 4 was really reliable and somewhat compatible with T-Mobile, but it didn't support some of the bands. Anyway, I immediately noticed the lag on this phone when compared to my Note 4.
After messing with several settings and doing a lot of reading online, I decided to try a different launcher and it made a huge difference. I'm currently using Nova Launcher. It takes a while to set it up exactly how you want it. I still found it a little laggy, but instead of the 7 seconds it took to open apps, it would take about 3. I then went into developer options and changed window animation scale, transition animation scale, and animator duration scale from 1x to .5x and apps now open and close almost instantly.

So how do you like the V20 now compared to the Note 4?
Agree even if can be hard to completely abandon your favorite launchers & some live wallpapers it's worth experimenting with other launchers-wallpapers & you could first try turning off those 3 animations in developer options to make it feel snappy or if you like them change them to .5x as suggested by Archangel1183. For laughs you could try all 3 animations to 10x :laugh:before turning them off or down as low as you like.:good:

Any of you all with Sprint. If so I have sinking suspicion their crappy over saturated network is the cause of most of the lag.

Just reread your original post & that does sound like crazy lag, are you saying when you're home (probably on Wi-Fi &/or with better signal?) not plugged in, the lag is dramatically less only or mainly getting that crazy lag when not in that environment?
How often do you reboot & what apps do you typically have running? Did turning off those aforementioned animations make it more snappy?
If you think it's doze you could try http://www.tomsguide.com/faq/id-3026187/disable-doze-android-marshmallow.html
Have you tried a different battery to see if it makes a difference on your battery drain, anyone recommend one like https://www.amazon.com/gp/product/B01MR3NHAK ?
Did you buy your V20 online or could you pop in a Verizon store to see if an exchanged replacement makes a difference?

yeah its mainly when I'm out and actually need to use it quickly, that's when it lags the most lol go figure. I'll check out that doze link. the battery itself is fine... usually it doesn't drain like crazy, but my new job is a metal building so it's awful on the signal. gotta airplane mode it! I have a us996 so I never played with any other version before.
Sent from my LG-US996 using Tapatalk

I have found on my T-Mobile variant that if I run a AOSP ROM the lag is less noticeable and most of the time is less frequent.

Do you have Facebook and messenger? Uninstall them both and see what happens in a day. Also, are you rooted?

rooted yes, Facebook dear god no.
Sent from my LG-US996 using Tapatalk

Install magisk latest beta and try crossbreader in the downloads of magisk manager. It removed all signs of lag for me.

When I had this problem is was the wi-fi trying constantly to connect to every router in the area. I set smart manager to automatically turn wi-fi off when I leave home and back on when I return and haven't had a problem since.

You might want to double check as I have the T-Mobile variant and stock rom came with Facebook already installed. After disabling that and Lookout, it ran a lot better. Think there is actually a thread on here somewhere about those 2 apps lagging up the device

nah I've deleted Facebook immediately when rooted.
Sent from my LG-US996 using Tapatalk

you probably have frozen or disabled some apps that causes the lag. I actaully did a backup first before trying to uninstall or disable that looks bloatware to me. I disabled some LG bloatware apps that causes lag on my phone and camera. I don't know which is which but then I manage to install back my backup and start all over again.
