[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?
Sent from my Nexus 4 using xda app-developers app

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.

Galaxy S4 - To Hot to handle!!!

Hi guys,
Would like to check up if any one of you faced issues with samsung galaxy s4, heating up after usage of gaming, downloads, browsing, talking on the fone, etc
if yes, then post your issues here and we all can work together to resolve this or atleast know whts causing it...
regards,
RK

I am using the octa core variant. It gets pretty hot when I play ironman 3. probably due to the intensive graphics

Nope sweet as...

Blame it on the Snapdragon 600 or the Cortex-A15 cores, whichever you use. These babies burn like hell when you push them to the max. I suggest you to quickly root your phone and downclock via SetCPU . My SD600 is butter-smooth still at 1.35GHz and runs much cooler.

Of course any powerful processor on this earth will get hot when you use it fully. You can't put HSF in there

but my phone went warm when i sintalled avast antivirus and batter ended quick! i uninstalled it and pluged it in charge im sure it was antivirus and nevr gonna happen again!

No offense but news flash the energy in the battery is converted into heat when you use the phone.
I feel like many people complaining about heating or overheating have units that are working correctly. It's a quad core with a big battery it's gonna make some heat when you put it to work.
Overheating specifically means heating to point where it no longer functions, not the point where you simply believe it is too hot (assuming it's not burning you) or even worse you think some temp readout is too high.
Tl;dr if your phone isn't shutting down or burning you it doesn't have a heating problem. If it's warm at idle your battery is draining you have a software idle drain problem not a heating problem.
Charging also generates heat. My phone will get pretty warm gaming but only really gets heated up on the back when charging. It's all fine. My S1 got toasty and never failed, one time I left it in a hot car it was so hot I could barely touch it and it was still working fine. Just chill.

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.

[Q] Does overheating kill my S4 (I9500)

Does the overheating eventually kill my S4? I have CM 11 (Android 4.4.2) and the problem still persist. I can't update via OTA since its rooted. I also don't want to lose any apps because they are large apps and dont want to bother to download them again. So will it actually gonna kill my S4 someday?

The Android 4.4.2 for S4 is leaked version. It is not published Officially by samsung and it may has many bugs. (eg. overheating, ...)

Overheating can eventually cause some serious problems. The board is able to adjust slightly with flexing caused by heat, but eventually soldered connections will give in and break if your device is getting extremely hot. When or what is causing it to get so hot?

@martikp When smsung officially publish it, do i have to reinstall CM so it fixes the overheating issue?
 @megamanDJ It overheats when browsing, playing games. Does this eventually break the LCD screen ( not the gorilla glass 3 ) ?

No it won't break the HD Super Amoled screen.
Overheating will eventually cause logic board failures and shorten the batteries' life span

So if my phone is a little hot can this still happen?

Not a little bit hot but perheps if it reaches 85 degrees+ all the time. But even in doing so it will still (from my experience) last longer that you'd ever keep this phone for.

Oh the is there any apps out there that tells you the temp if my phone. Something that is easy to set up?

They have quite a few apps out there for monitoring temps and whatnot. I personally use Android Tuner for everything I monitor. As a huge plus, this app is one of the most versatile apps (especially if rooted) I've come across and have had for a long time. Its good for adjusting or tuning down anything that may cause overheating as well as view summaries of the culprits

I agree. You don't hear too often about someone's phone overheating to the point of failure. I've seen one phone that would get so hot you almost couldn't hold it in your hand, and had a habit of doing that but was ultimately broken months later by a shopping cart.:silly:
Still a decent monitoring app (among dozens on the market) can help you monitor temps and pinpoint when, where, and what is causing problems.

Thank you the app works. Is there anyway to drop the temperature as low as you can? Like 26 C? I disabled my Google account stuff and sync and removed the sim card because I use this phone as a gaming device. When I play a few rounds of subway surfers it already gets to medium warm and for 3D games it gets warmer more faster.

I would say you are safe in that temp range. Its when you get 80 C and above that that's causing damage. Also are these temps from the battery or the CPU? The CPU can and will get to 60 C temps at times which is normal.

CPU I played the game six guns for almost an hour and it didn't go over 65 C and I think I totally screwed up my ext SDcard

If you are having heating problems while playing 3D games alone then you might want to try experimenting with using different GPU settings. You can try tuning down the frequency. It may or may not help with temp being its only a frequency setting. Try also using the app "Greenify" to put as many of the remaining apps that you don't absolutely need running into hibernation. Greenify is a lot more efficient when it comes to keeping apps from using resources.
Sent from my SAMSUNG-SGH-I337 using xda app-developers app

How to adjust the GPU frequency settings? Does this affect the quality of the game after its adjusted? But I do not think adjusting the GPU frequency settings will work. The overheating problem is caused by the CPU. May try Greenify app.

If your GPU is capable of adjusting the frequency then it will show you in the Android Tuner app next to the CPU settings, but you're right it wont help with overheating. You can set your CPU governor to "powersaver" and underclock by sliding the max frequency setting down one step at a time until you notice a difference in temp. Greenify is a huge help mainly with battery saving which in turn stops a lot of unnecessary CPU draw.

Does under clocking CPU will cause large 3S games crash? Hope it doesnt

Bad idea. When I change it to power save it makes every sluggish and laggy even I turn one step down the CPU thing its sluggish

It was off 5 the charger for 27 mins and screen on time 22 mins. Cell reception is great and I use WiFi most of the time. I use a lot off game apps like field runners and candy crusg. I did a factory reset last night and the battery is at 66 percent and I unplugged two hours ago. I've been playing like 20 mins of field runners and I froze all the bloat. I don't get why the battery is not as good? Did I buy a bad one from ebay?
