[Q] Nexus 4 Heating and Battery Issues

Hello so I bought my N4 on the Dec 3 batch and got it around Feb, the works fine and all but I have 2 main questions
1. The phone gets hot doing simple tasks like browsing the web or watching a youtube video. I am running the CM 10.1 Nightlies and Franco's Kernel r110. Sometimes the phone can get really hot which I then stop using it to prevent any damage. Does this have anything to do with the Custom ROM or kernel because my friend's N4 is stock and unrooted and hes doesn't have any heat issues.
2. The battery on the phone is not what I expected. I hear people who get 4-5 hours on screen time, but I get around 2-2.5. Also I am on a Canadian provider which is Mobilicity if that has anything to do with it. I leave 3G on mostly and just surf the web when the screen is on.
Thanks for any input you guys leave.

If you can take it back to stock and don't root because that is why your friend's N4 is normal besides what more do you want that the N4 doesn't have?

I like the root features and also cm 10.1 if its the ROM that's making it overheat then I know to change or find a better one

Hi,
As always "overheating" is very subjective, it depends on how you feel the heat.
CPU / battery temperature?
In any case there is a protection, a thermal throttling. At certain CPU / battery temperatures the CPU frequence is automatically lowered to help reduce the temperature. In extreme temperature the phone shutdown to avoid damages so no worries.
In 3G the phone heated a little more, no problem here that the phone heats up when you re browsing or you're watching a video on Youtube.
You can try to undervolt a little to see if that helps.
As for battery life it depends on too many factors... CPU settings, screen brightness, signal quality, etc...
Search about your questions in this section or in the General section, there are lots of threads about it.

What temperature does your phone actually get? When running stock it would be impossible to see my phone get other 43c and that was only under very heavy gaming but would usually be at 32-36c ive noticed my phone does get hotter when using mobile data instead of wifi. Now running rasbean with franco m1 and temps abit lower gaming has improved greatly but i dont think there is any difference in battery life compared to stock but your 2-2.5 screen time does seem abit low as i get with just web browsing maybe few youtube vids and few minutes of games around 4 hours screen time but i also envy those who are getting 5+ hours

Forgot to mention thats 4 hours on wifi on mobile internet i should be able 2 get over 3 hours

The phone gets hot very easily in my opinion idk the exact temp but I have the ringke slim on it and its definitely noticeable from the top of the phone to the bottom. Also does my carrier have anything to do with it because brightness on my phone is pretty low and simple stuff tends to drain my battery.

When i was using a case on my phone it was getting hot from top to bottom but now i don't use case it doesn't get as hot and usually stays cooler at bottom half. I have found most accurate way to check your battery temp is by going on call and dialling *#*#4636#*#* and a hidden menu will come up and tap battery information you will see temp, there was an app that had same info but cant remember name so when you think its hot dial that code and let me know what temp it shows. Also are you using mobile internet or wifi when its getting hot?

I think it usually gets hot when using 3G so I'm assuming mobilicity isn't that good for this phone? Also I can clearly tell its the top part that is hot when the case is on
Sent from my Nexus 4 using xda app-developers app

Yep mine also gets noticeably hotter on 3g and yeah it gets hot at the top but after a while will spread to bottom to thats normal. I am currently running rasbean rom with franco milestone 1 and also downloaded pimp my rom from play it has various tweaks and mods so i just flashed battery saving which supposed to help with battery not sure what it does though lol but i managed to get 3 hours 40 mins screen time half of time it was on minimum brightness and other half on 40% was just internet browsing and im sure you will agree that is very good considering i was using 3g the whole time
Sent from my Nexus 4 using xda app-developers app

Just an update you should try undervolting on franco as i have now done it and it definitely helps with heating and i am pretty sure it has vastly improved my battery life if your interested i will post the values i have used which seems to be perfectly stable so far
Sent from my Nexus 4 using xda app-developers app

Yes please, do I need any app for this or can I just do it in the settings?

do you have the franco app? As that was what i used to change my setting if yes just go on frequencies/voltages go down to voltages and change from there i have attached screenshot of my setting and make you do not set voltages on boot as if it is unstable your phone is not going to boot up if that is ticked, you will have to change that everytime you reboot until you are sure its stable then u can set on boot

Do you have a bad signal? Because if so then that will drain your battery a lot more quickly and also possibly make the phone heat up more.

Quick lil question

Hey yall i'm using a nexus 4 running cyanogenmod RC with setcpu on and franco Kernel.
Does my phone still throttle its cpu speeds when it gets to a certain temperature? Like on stock nexus 4.
I have done alot of research but i cant find an answer to this question. Also i am asking this question because i dont want to overheat my phone and kill its battery.

Franco kernel throttle CPU when it reaches 70c by default
Sent from my Nexus 4

Just flash rasbeanjelly + Trinity all heating issue just go away for sure.
In Trinity I find colour are faded so you can try different kernel .
Sent from my Nexus 4 using xda app-developers app

Ok and ok but I think I'm through flashing stuff lol except for an update.
Anyway what temp does the stock nexus 4 throttle? Because 70 degrees Celsius is to hot for a phone, even most laptops cant handle that temp.
Sent from my Nexus 4 using xda app-developers app

Not sure what temp stock kernel starts to throttle but if it reaches 80c it will power off to protect it. It is very hard for you to reach that temp though
Sent from my Nexus 4

K, you have an recommendation of what is a good temp to throttle my nexus 4 at that wont allow the heat to damage the battery or phone?
Sent from my Nexus 4 using xda app-developers app

70c is hot but not too hot, 90c is a bit closer. I believe the auto power down is somewhere between 90-100c. The chances of your phone but ing damaged by the cpu or battery being too hot is pretty much nil. Don't worry about it and just use your phone. If it's actually in danger of frying the chip or the battery, it'll shut itself down.

If it really bothers you, set the throttle at whatever temp makes you paranoid. There's nothing to freak out about.

What temperature can nexus 4 handle?

Mine idles at 55 degree Celsius and throttles at 60 so there isn't much room to go. I can increase the throttle temp but was wondering if that's safe and how much heat can nexus 4 handle
Sent from my Nexus 4 using xda app-developers app

The CPU will run fine up to 100°C at which point the phone will shut down to prevent damage.
The battery will run fine up to 60°C at which point the phone will shut down to prevent damage.
The CPU will throttle default at 60°C which to me is a little low.
The battery will run fine up to 48°C at which point it will report it's status as overheated and throttle.
I have my CPU throttle at 75 and have been fine for months. I would advise not raising the bar too high because I'd say you up it to 90. All that you will accomplish is raising the battery temp quicker and thus still end up throttling.
The battery temp is generally the heat that you feel coming through the phone. So by making the battery heat up quicker by upping the CPU throttle threshold. Your device will become hotter to the touch quicker.
There is a balance between the 2 which I feel Google got wrong by setting the CPU threshold at 60. I would advise 70-75 but that Is purely my preference.

So the phone will run fun until battery is 48 or 60? I think 48, 60 seems too hot
Sent from my Nexus 4 using xda app-developers app

It will throttle at 48. It will shut down at 60

Phone overheating issue

My G2 tends to get worryfyingly warm when im using a bit more cpu intensive tasks. The cpu managed to get to 67°C when playing 3 races in NFS Most Wanted and managed to get 76° when doing Antutu benchmarks twice and it started throttling. And battery temp stayed around 40~45°. Idk, if this is supposed to be normal(please bear in mind my previous phone was HTC Evo 3D, which barely got hot ). When idling, the phone is just a bit warm. I'm running OptimusRs Pro V4.1 Stock kernel. Is this supposed to be normal for quad core phones or should I get it to service?
Sent from my LG-D802 using XDA Premium 4 mobile app

Oh, and when phone is idle, the cpu is 42°C and battery is 32°
Sent from my LG-D802 using XDA Premium 4 mobile app

This is normal the g2 is a very powerful phone without a fan eventually phones will have to have small fans and phones may be noisier than today's phones

I know that, but it tends to get hot very fast, a couple of minutes heavy tasking and its already throttling
Sent from my LG-D802 using XDA Premium 4 mobile app

Is it really normal? I mean after 10 mins of browsing even the screen gets really hot..

see if you can check your kernel's cpu profile settings. could be that it's not allowing the cpu to idle when it should be. alot of times there are various profiles you can set it to 'on demand/powersaver/ect...' and this will change the behavior of the cpu's throttling.

Well now we're in the summer and the phone will naturally get hotter since the only thing that cools it down is the environment. If you're browsing under hot sunlight with 100 percent brightness then yes, it is going to get really hot.

its not normal bro. i have the same issue on all aosp roms and cloudyflex roms. my phone becomes really hot. if you give a shot at cloudystock 2.2, your phone wont heat up at all. try it out and be sure to make a nandroid before. just incase if you change ur mind and want to get back to this rom. i wouldnt recommend it though, anthing above 25*C for the battery is bad for its health since its a lithium battery.while the cpu heating up to 70*C is fine i actually use custom throttling to reduce my phone heating that much, i keep the throttling at 60*C

No it gets hot even at 60 percent brigthness while browsing. NFC, BT, 3G are off, i am using only 2 widgets, The top of the phone gets really hot... my sis has S3 and it never ever gets that hot, so do my old Huawei phone..

Overheating z1 compact

Folks,
I am so frustrated with Sony.
JB was working more than well, that they asked us to move to kitkat
Now the very last version has transformed my mobile into a mobile oven.
It is so hot that I am afraid to leave it on I am afraid to damage the battery...
Anyone experience the same issue with the latest firmware?
Build xxx. 757
Thanks for your help

Mine is around 65 c with boinc running 100% all 4 cores

Not normal, my phone doesn't get hot at all, though I do live in the UK and it isn't exactly hot here in the first place.

Media Server loop. One of your media file is corrupted ... so cpu usage is long, battery life is short and phone is hot !!!

thanks for the wise advise, I checked what was transforming my phone into a heater, it was INSTAGRAM
for some reason it was not working well with KK, after uninstalling it everything when back to normal
I will try to reinstall it to see if it helps
anyways thanks for your help guys

can you explain please,i just got phone couple of hours ago

Have you rooted 4n if not do it with root tool in developing section. Getting Temp I use app called trickster mod from play store. For battery stats I use better battery stats from xda forum

will attempt root tomorrow,any advice on stable ROM

I use stock with pimp my z1, xposed inteli 3g and Greenify I'm ok with it

I played dead space for 2 hours straight while charging, the phone remain at 42 degree. A bit of heat is ok
Sent from my D5503 using Tapatalk

mine is not heating too much, but i've notoced, that when it is hot i got some vertical flashing lines in green colour, something like 8-10 one from another, on whole screen. It is noticable mostly on datk background. Any idea what could that be ? Unfotunatelly my camera can't catch those line so photos are impossible to make. THanks

my phone has never exceeded 55 degrees celcius, even under heavy load

Mine is to hot. 49-51 on light usage. Heavy load 55-65 celcius. How to fix it using trickster mod? Im using D5503_14.4.A.0.157_WW-SU2.40-DualR159_DeoZipA_XpoApp_torch_Cam4K.zip

People reported .157 consumes slightly more battery than .133 generally while .133 is the most battery saver rom, maybe you can downgrade it.
http://forum.xda-developers.com/showthread.php?t=2401988
If you want to stick with .157 to get the latest features, change the default governor from Interactive to On-demand(set on boot) and enable MPDecision(set on boot), this should give you some help. Also use Greenify(donate) to freeze some unused apps to free up memory/cpu and battery.
