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.

Alright I wasn't going to make a thread on this because this topic is already discussed elsewhere naturally but I feel my situation is different. All over the place I see people reporting great battery life with ICS.. well mine is HORRIBLE. I just flashed the latest nightly for Pete's bugless. I didn't change the kernel. Everything is stock. Only a few apps installed. Noop for scheduler and ondemand for governer.
The phones been off the charger for 55 minutes and I'm sitting at 76%. Idk what's going on. I've tried so many rom/kernel combos and I seem to get the same exact battery life no matter what. Around 6-9 hours with less than 1 hour of screen on time.
Things I've tried to combat this:
Undervolting
Freezing apps
Restricting background data
Underclocking
Brightness set to auto
And I'm sure a few other things I'm forgetting about. I've done all this and still get ****ty battery life. I've flashed the new radio hoping that it would solve my issues but no dice. My signal strength reports at -67 dbm yet the bars never go over 2. 3g or 4g. Even after updating plr.
On gingerbread cm7 I ran brightness at 70%, ocd to 1.4ghz and always got 15+ hours.
For the love of god someone help me. Cuz I think my phone hates the cream sammiches.

try this kernel, trinity teuv underclocked/undervolted kernel, oc'd gpu http://goo.gl/rY6ga
and do not set brightness to auto, its a battery killer. i keep my brightness at about 20-25%.
also, be sure to fully discharge your battery then charge it completely, after 2 or 3 cycles you should be good.

I do this every day lol I let the battery drain to around 15-30% before I plug it back in.
Screenie: 1 hour later and I lost another 25% this can't be rom or kernel related. As I have tried trinity already and the same thing happens

i was having horrible battery drain after flashing a new rom & kernel - i finally figured it out that my APN settings were messed up and I re-entered them according to the correct carrier settings.
i don't know if that will apply to you since it looks like your 4G data is working properly, but since I was on wifi 99% of the time, as soon as I went off, my data didn't work. but it's something to look at.
4 hours later I'm down to 4% from a full charge.

I would be interested to see what your battle life diff is without 4g switched on. Also in that 4 hrs what was ur screen on time?
Have you thought of trying a new batt? Just got an OEM Samsung for 5 bucks on eBay. Worth a shot.
Oh remove fb app it blows...install friend caster way better less batt make sure you change the sync interval.
You could also try green power from the market to manage your data use while screen is off.

Ok here's how my battery performs back in cm7 nightly 174 gingerbread. Almost 4 hours and only 25% chipped away. If you look above you'll notice I lost more than 40% in the same time with ics. And I'm doing nothing different. I'm even overclocked to 1.3ghz ondemand with noop for a scheduler.
I think I'm sticking to gbread until official source is out. Maybe then ill get the same battery life.
Sent from my Nexus S 4G using xda premium
That is really weird, if you have time try Milestone 3 and SG's latest kernel and just leave the settings stock . I get wonderful battery life with it hopefully you do to
Oh and are there any apps you are using on ICS that you aren't on CM7?
Sent from my Nexus S 4G using XDA App
Nope. Lately its only been a handful. I actually have more apps installed on gbread to achieve some of the features that are baked into ics. I just don't get it. Ics hates my phone. I even used the GPS today. So weird.

This. If you are installing the same ol battery-draining POS app then you are not going to fix it with any rom or kernel.
So you guys think my batter watcher widget is preventing my phone from sleeping properly? Ok.. I'm on cm7 right now. Battery is def back to normal. And this is with bacround data on. Ill delete bw and get better battery stats.

Better battery stats is not the same thing as other (mostly useless) monitoring apps.
Look. 16 hours on gb. If none of my apps are killing the battery then what could it be?

Hi I have searched all over for a solution. Most point to 3rd party apps and wakelocks but I don't think these are the case because I am not losing battery while it is turned off. Today the only thing I used my phone for was browsing the internet and I still only got 2 hours of screen on, which is still better than usual. When I use my phone regularly I only get around 1 hour. I am on PAC ROM and Faux's kernel. And also sometimes it gets hot but not as much as it used to.
Here is some pictures of my battery.

wow, chrome is a HUGE drain!
im a heavy browser user, heavy user user generally too. the aosp browser never drains(ed) that much, ever, no matter how much i used it. on average, i get about 3.5-5 hours screen on time, depending how i used the phone for that day. maybe its time for you to use a different browser or try a different rom/kernel.
Try using greenify , your battery stats look normal to me. If your using your phone in a bright area its going to kill your battery faster, and if your screen is doing that its going to make your phone hot. Using it in direct sunlight will kill your battery very fast.

Hey
I bought my nexus 7 about three days ago and I think I have an issue.
When browsing the internet or watching a movies my nexus can reach 35c and when playing tegra 3/Gameloft games it reaches 39-40c is it normal? Happens to all?
It's little annoying and I can't enjoy these games....
Any ways to solve this problem?
What are you talking about, thats waay to low, my OC-ed nexus 7 can reach upto 70c and about 69c should be the top limit, 50c is usual temp, or atleast it should be when browsing

What the hell? 70 celsius ? you can cook with your NEXUS 7 LOL
How you deal with it?
well you know, undervolt for about -100mv, which is pretty stable, if necessary lower my oc to 1.5 ghz and it never crosses 63-64
sorry if i offend you with this question, but is it possible that you were looking at your battery temp, not cpu?
because usually those temps are from the battery, it seems just too low for almost a high end device (atleast it was)

Yes I mean battery temp
minecraft
I have had the same issues with the heat on my device. I notice it gets pretty warm quick right where the rear camera is and also the glass gets pretty hot too. I been playing minecraft and it heats up quick, I checked the battery temp with an app and it reached to 31C. This was from playing for about 15 minutes. Browsing the net or watching youtube doesn't have much effect but watching a video with the browser did make the device pretty warm. I gotta admit when playing games its pretty uncomfortable.
Even 40c isn't that hot for an electronic device. I remember my old Galaxy S 4G used to get a battery temperature of 52+ while charging and playing guns n glory in a non air conditioned guard house. Every so often I'd stick it in our mini fridge for a few mins to cool it down.
I would've loved to see how hot that poor processor got, but battery temp was the only one you could check on that device.

The only kernel adjustments were to the governor and scheduler (using smartass and sio, no alterations to either). I just tried using the rescan media disabler apk to see if maybe my media was causing the phone to run hot. It seemed to be the only thing going in the background.

Usually the heat starts when I am using the phone, which is usually browsing the internet or reading up on sports news. Screen off or charging I have been OK so far. As far as the battery, it appears to be in good physical condition. I also have 2 OEM batteries by Anker that experience the same issue. So far so good, though - been using the phone moderately since the last shut down earlier today and it seems ok at this moment.

if it heats up really bad again try underclocking a step and see if that helps.....phone might be getting hot because your chip is poorly coated and the higher frequiencies are heating it up enough to shut the device down. you may have to underclock by one or 2 steps to ensure its not a consistent issue.....worth a shot anyways. unless you do high graphic gaming and multitask with 8 apps at once your really dont need the higher clock speeds anyways.

Good idea, hopefully I won't need to! Appreciate the feedback.
If you just got this phone Friday then I would return to stock, run triangle away and exchange it. What you describe isn't normal, why take a chance and get stuck with a bad phone when you are within the exchange window.

Seriously guys, your S4 doesn't heat up at all???
I'm back to 100% stock everything (kernel, rom) and running this for a couple weeks. I've completed several factory resets and whatnot as well through those weeks. I know my install was clean as could be.
Now, my phone gets hot at seemingly random times. sometimes playing games, for sure while navigating with GPS and sometimes when its just sitting there. I monitor things with Better Battery Stats and keep an eye on the CPU Spy. I'm achieving deep sleep most often. Some of this is caused by the god awful Sprint service here and the constant search for signal, but I was hoping that this wouldn't get as hot as the S3.
so, should I seek a refurb from Sprint? I have the insurance. I am just afraid that a refurb would do me no better.
My biggest gripes are heating up occasionally, WiFi disconnect issues. I hope 4.3 can help some of these.
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?

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..
