Hello everbody,
bought 2 weeks ago the Nexus 4 16GB and I'm very happy with it.
But i have the problem, that the device restarts when it is under load, means i play or watch something what needs
the full power of the CPU and GPU.
It happens a lot when i play Iron Man 3 The Official Game or Dead Trigger.
Than the device freezes, can't kill the app or even lock the screen and after 10~ seconds it reboots itself.
Active Wifi, Bluetooth, 3G or not doesn't make any difference.
The only strange thing is, what i discovered after a few crashes, is that the battery gauge stands still before the crash and after the reboot the gauge drops to it assumed level.
Screenshot as attachment.
System: Android 4.3 Stock (with this last mini patch from last week)
Does anyone have a idea how i can fix this?
I tried, to charge the battery while android is off and to turn android at 100% on, but this doesn't help.
Sincerely,
GTrash81

Did you undervolt the CPU?
If this is happening without rooting/etc... then I would definitely get a replacement. It sounds like the processor is overheating and causing a reboot rather than throttling.
Today i checked if the device is getting too hot.
But after 2 minutes playing Iron Man, by 9°C outside (i was on the way to the city, waiting for the train), it rebooted.
So i started the game, deactivated the display and put it on the table. After 4 hours i checked the game and played over 10 minutes without a crash.
So what i think is, that these two don't like Trim (most new feature with 4.3) or the are badly programmed and must reload/refresh objects while playing and Trim must work to clear temporary files.
And they are badly programmed, because i red at the developers page, that a few other people have the same problems.
So excuse me for wasting your time. But hey, to err is human.

Hi there. I was just wondering if anyone else has experienced this issue.
I used to think it was only caused when I changed my phone to a custom Kernel but its also happening on the stock rom and kernel too and even a reset and wipe didn't fix it.
Basically after a while of usage the phone just gets extremely slow and laggy and it seems to be related to GPU not CPU as when I run Quadrant my CPU scores are the same when this issue happenes but in graphic tests the fps has gone from 60fps to 30fps.
The only way to fix this is turning the screen off and then back on again. Once I do that it goes back to normal.
Its not a heat issue or DVFS issue as I turned DVFS off and and it still happenes and my temps are the same as usual. it just seems to happen randomly after iv been using it for a while.
Has anyone else experienced this and does this seem to be a fault?
Scrolling through the home screens becomes really laggy when it happenes like the speed has halved so its easy to spot.
I haven't noticed anything in stock.
Maybe trying a firmware 4epair through Kies. Not Odin.
And then try again in stock and if all is well try in custom
Hello guys!))
I am running android CM12 android 5. Before installing this I had omnirom 4.4 and that was also lagging horribly so had uninstalled that and then applied the CM12 android 5. I had followed all the instructions to the exact point -flashed,cleared cache data etc all correctly.
First few days it ran satisfactorily but then again started to crawl down horribly.
I must mention that my tablet had a bad fall a year back and the screen is having multiple spiderwebbed cracks but working 100% correctly (thanks gorilla glass!) So is it possible the cpu suffered something because of it? I think that is unllikely though because of how perfectly it performs sometimes, no problems in flashing etc.
Now let me describe how exactly it is lagging.
The apps slow down to a crawl. Multiple seconds delay in input after that. Delay in switching apps too. I can try ramping up the speed to 1.4Ghz (by repetedly pressing the apply button in CPU speed app because of the input lag) and then it works smoothly then for sometime. I think once or twice i noticed that the cpu speed while working had slowed down to 300+Mhz something ..... so is that the reason for the lag? The cpu speed is normally 384Mhz - 1.0/1.2Ghz , i dont mess with it often. Oh, and it sometimes restarts by itself randomly too..like after like few seconds of hanging.
I cant browse properly, cant read books smoothly, cant even switch menus and apps properly...it's a total killjoy experience :'(
I have already formatted to factory three times before this but the problem returns after few days or weeks. Have also done f2fs formatting. I miss the days of butter smooth honeycomb& ICS experience....
Please help me to get out of this problem. It's not a simple rom problem i thinK? :'(
People are complaining that they are facing lag,heating issue,battery draining........in Lollipop v5.1
Here is the solution........
1st- Before Upgrading to v5.1 do wipe and factory reset
2nd-take out your SD card before updating to v5.1
3rd-Again do hard reset after installing v5.1
4th-Done
Please Do hit thanks button if I helped you
Lollipop v5.1 Review by me
Antutu Score increased to Approx 40K
Games like Real Racing 3,Asphalt 8,Nova 3 doesn't lag anymore like kitkat do....(kitkat is very bad update for TN7)
Can't install benchmark tools from play store.
Browsing in Chrome is also improved
Battery performance increased by 15-20%
Everything is buttery Smooth...
Performance mode is hide by nvidia. Don't know why.(Download Activity launcher then select all activities then settings->setting>nvcontrolpanel)
Graphics performance increased a bit.
Music is Same.
Have a Nice Day Sir\Mam.....
Enjoy your LoLLipop ��
is this confirmed 100% that hard reset solves all heat and performance issues if i didnt hard reset before install this update ?

Yes I did v it... It worked for me...?
it resolved the lag and heating problems but still having problems with google apps connecting through my wifi connection. even if I can basically browse the web using chrome, I cant add a google account in the settings cuz of the issue im having.
Still having battery problems after this. The battery doesn't drain as fast but it takes 3X longer to charge.
didnt solve this that hard reset.. still getting micro freeze lag in games and tablet heats up to 40c playing games like clash of clans and boom beach and this is with 2 cores and 30fps limit set , if i plug in charger it seems stuck, only way is to turn of tablet and turn in cable then it charges normaly... no this is something not right here i never had heat issues or lag in the games i played what a disaster
It even stays at 41c even if i dont play any games, its like the cpu is at 100% for some reason but i did hard reset so wtf is this nonsense ?

When you say "hard reset" do you mean a reboot or a full factory wipe from the settings menu? I factory reset mine and have had no issues except a little stuttering, but it's far less than it was for me before the update. Make sure you're factory resetting from the settings menu and not from a custom recovery... it will erase everything and reinstall the OS from the factory image of the 5.1 update, which a wipe from a custom recovery doesn't do.

Installing a new ROM sometimes does this. I've had similar problems with my phone. Solved by calibrating the battery.
It may take several iterations though.
EDIT: by 'this', I mean heating up and draining of battery mainly.
I did a factory reset yes wiped everything, not just reboot the device sorry but problem is still there and this is from using the tablet over a year never any battery or heat problems.. all started after i updated to 5..1
so why do i have issues then ? it must be faulty update im not the only one having heat and battery problems now.. I feel cheated the update promised increased performance and stability improvements i dont see any of that so far only problems and negative stuff..
and how do u calibrate the battery then ?

There are many versions of essentially the same thing, nothing is guaranteed though, you can google it. Usually it requires root, I guess that's not your case.
So what you have to do is switch off your device and let it charge to 100%. Do not unplug it even then and let it charge for 2-3 hours even after that. Switch on, use it normally. If it's solved then good, if it isn't repeat the process. Like I said, it could take several iterations.
(I calibrated even my laptop's battery the same way in the past. I thought it was gonna die but it worked for another year after that.)
My experience:
A while ago I flashed my phone with unofficial custom cyanogenmod recovery. It worked flawlessly. I used to manually flash the updates as well. This one time, I encountered battery heating up and draining like hell, even if the phone was connected to the charger, battery percentage would go down with each second. Luckily my phone was rooted. I tried calibrating apps from Play Store and it worked. I flashed updates after that as well, but recently, I flashed a new ROM update, and the problem is back. But this time, it's not resolving. I think I've tried every possible way. After a few tries, battery is not heating/draining when using normally, but as soon as I plug it for charging, it gets heated up. (EDIT: it's alright now, without doing anything else than regularly charging and using normally).
Charger is not faulty, I'm sure, plus I've tried a couple of different chargers. ROM is not faulty, if it was everyone would b having the same problem I guess. Also, I re-flashed the previous version, which used to work alright, but the issue remained the same. I'm hoping this would be resolved after a few more tries, or after a new update. As I said, it's not guaranteed, but it works sometimes.
People may tell you to delete the batterystats.bin (this is what calibration apps do, requires root). But a google engineer confirmed that it does essentially nothing as whenever you charge to 100%, the file is automatically reset. http://www.xda-developers.com/google-engineer-debunks-myth-wiping-battery-stats-does-not-improve-battery-life/
Although I'm not having any battery issues, I still liked it better before this update. I think I'm gonna downgrade it, if there's a way.
Sidenote: If you ever decide to flash a custom recovery or OTA update, make sure you have high percentage of battery. Flashing ROMs on low battery can cause issues too. (I don't have any evidence for this, just experience, so I may be wrong.)
battery problem is due to performance setting.........every app uses 100% 4Core max limit of tab.... even playstore,chrome etc like app
If u have back up on TWRP u can run TWRP via fastboot. Then install the SuperSU.zip with recovery and make restore. All works fine and 5.1 is gone.
fix heating and battery drain issue.
I solved lag issue by doing this, hope it helps.
So I don't know when this started happening but almost every single game on my Galaxy S7 lags after about a minute of playing, like the frame rate will get cut down from 60fps to a choppy 30-50fps, and stay that way unless I exit to the home screen and back into the game or press the app switcher button for a second and go back into the game, then it jumps back to 60fps for a little bit and the lag goes away but it always comes back.
I have no idea what's causing this problem and I'm tempted to factory reset my phone to see if that fixes it because I've tried almost everything (disable game launcher and tools, disable the packages, game mode, high performance mode, delete cache, rebooting, etc.)
Does anyone else have this problem and could it be a certain app using resources in the background that's causing lag? I'm on the stock rom from at&t, no root and no bootloader unlocked, everything is pretty much vanilla.
Finally after months of trying to figure this out, I fixed it by pure luck.
Every Galaxy S7 user should do the following:
1. Download Game Tuner
2. Create a custom profile
3. Set FPS to 60
NOW ON TO THE MOST IMPORTANT STEP!
4. Set HW Performance to +4
HW Performance affects the stupid throttling that games seem to do that prevents smooth 60fps in an effort to preserve battery life and keep heat down I'm guessing. Setting it to +4 fixed all the lag I was getting in every single game.
