hey
i have the same problem only when running aokp and miui roms.

Let me guess, you have overclocked to 1300 or 1200 MHz?

Yeah. We need to know when it overheats. Just saying it does doesn't help.

You are right. Then RombMIUI 2.6.22 kernel with air kernel. CFQ scheduler. Governor smartassv2 and freq. Min 200 and max 1200. Same problem with aokp. And even changing kernel example that of mat1x 22 nothing new.

Overheat during normal use, like surfing the Internet and surf the xda forums with tapatalk. But especially when I use it and is connected to the charger.

Have you tried scaling down to 1ghz? That should be more than enough for daily tasks.

Overheating caused most of the time by
- poor 3g field power in your environment or
- by applications running endless in the background
For the first case just switch to 2g and see if it helps, for the second case uninstall any apps which you dont need or install a program which shows you the processor load: normally it shouldn't be over 4-10%

Surely it is because in this period is always on 3g, now I try to change to 2g. While with regard to the applications. The only WhatsApp are installed, and k9mail ebay app. Alla in background

Is your phone constantly awake(massive blue bar compared to screen on)? A rogue app can cause excessive heat. Snag CPU spy and see if your phone is actually going to sleep

yup, use cpu spy to check if its actually going to sleep or if its running at max freq. then check the battery and apps to see what has been running the most. I've noticed that Maps is usually the culprit

I realised that during (USB) charging the system process runs at 50-60% CPU. It could be the reason... anybody the same experience?

USB only charges around like 500ma vs the 750 the stock charger puts out. The phone doesn't fully go to sleep while charging via USB. That may explain the cpu speed, although that seems kinda high. Mine when hooked up via USB is probably 200mhz.

Working solution for JB Memory Leak

Solution to memory leak is to limit background processes to 4 only, under settings/developer options. Watched it 24hrs, never reached 700mb!!!
But keep in mind to set it again after device reboots.

Yes but the sistem charges all the user apps always and drain the battery...this is not the solution. That option is weak hardware in economics smartphone. ...is not our case.
Inviato dal mio GT-N7000 con Tapatalk 2

You might be right but constant use of over 750mb makes our note unusable. Other than that I havent noticed faster battery drain with limited apps.
I understand your point and this should be used as a temporary measure until someone comes with a better solution.

I agree with you. Is out a new leaked firmware lsd. Maybe fix this. Without a exynox code source release is not possible to fix memory leaks

Get gsam battery monitor or betterbatterystats and post your results here after a day of usage. There are many reasons for overnight battery drain (poor reception, running apps, etc).

I don't have problem during the day with the battery ...

Any weird config for sleep/screen off ?

My Nexus 7 tablet last night left its screen on overnight for no reason and drained the battery completely. Turns out it was an updated app that autostarted while I was asleep and re-requested new SuperSU permissions. For some reason the SuperSU dialog box switches the screen on and never goes inactive. Might have been what happened to you?

R: I don't know what happened
Maybe yes tonight I try to left the phone with the screen off and unplugged and she what happen if tomorrow the phone won't start I will reflash all stock and she if it is a ROM o kernel related problem maybe is something related to hardware?

Download betterbatterystats and find your wake lock.
Sent from my Nexus 4 using xda premium

enri do what suggested,trace all yours apps wakelock with both suggested apps (etterbatterystats and gsambatterymonitor.
post here the results after a night overdrain and sure someone can help you.hard to tell of hw failure without those data..
hope you solve the issues,bye!:fingers-crossed:

why not go to bed with your phone plugged in??

probably because his battery was at 90%...and everyone would think there's no need to charge it..and after that he would know the true reason of that strange behaviour,being all good during the day.
I think that it's not a low\poor reception issue,because it's not present during the day where he move and go through different places and lock with different gsm cells...it it's related to signal,i think he would had that issue also with his precedent phone,the maguro gnex.)

R: I don't know what happened
I see that faux kernel app cause me a lot of wake lock....

Car Navigation with Powerconsumtion under 500mAH

Hi,
i tried to use the nexus 4 as car navigation but i've a problem. The power consumtion in the scenario is to high.
Szenario:
- Bluetooth on to pairing with car radio for using the external speaker
- Display always on to watch the route.
- GPS on for navigation
- UMTS on to get latest traffic messages
As summary I need more power than 500mAH from my USB charger and the accu gooes slowly down.
I know that I can use a more powerfull charger, but my question is.. is there a way to use the nexus 4 in this szenario under 500 mAH?

Underclock, undervolt, offline cores, low screen brightness.
Ull lose performance alright

low screen brightness make no sense because it's necessray to see always the route, but disable one core is may a solution.
It can be profiled with tasker if the navigation SW starts

And maybe another nav app?

[MOD] Lower Brightness Display

Hi!
I'm looking for an application that can lower the voltage of the display.
I do not try to make an application filter for the screen. I need a real decrease in brightness.
Is there a solution?

UP: no solution?
Inviato dal mio Nexus 4 utilizzando Tapatalk

Well, gravitybox xposed module allows adjusting the screens brightness settings.

You can use lux auto brightness too.

Don't work on my Nexus4... On your own?
Inviato dal mio Nexus 4 utilizzando Tapatalk

I'm not sure if it's possible as of now to edit the actual voltages of the display, but I was able to achieve an extremely dark display (barely visible in pitch black room) by doing this:
Installing AK kernel, then installing synapse. Going to the tab labeled gamma, and ticking a box to set the LCD backlight to be raised exponentially.
I would highly recommend trying this. It should only take a moment.
Connor Baker

I already use the kernel AK.
I installed the application synaps, but I did not find any Tab gamma nor screen...

Fantastic, this is the great solution!
Thank you!

Damn, with this solution, I realized that I have problems with automatic brightness adjustment. This is always the minimum value .. Is it possible to somehow set the brightness levels right?

I believe that CM may allow you to set the levels for automatic brightness, but I'm not sure.
