try battery calibration

This is common problem on the galaxy tabs. Dont worry just yet. I had the same problem on the stock rom but as soon as I flashed task650's rom the problem dissapeared. Try just using the tab a couple of charge cycles(charge all the way, then let die completly). There also some apps on the market that will reset battery stats but I think you might have to root to do that. If you havent already, I would try to root/install custom recovery, because this gives you many more ways to troubleshoot your problem.

[Q] GPS-problem with mathkid's matrix kernel 9.0

Hi,
In know this doesn't belong here, but since I haven't posted yet, I'm not allowed to write in the corresponding thread.
I installed matr1x kernel 9.0 on my n4 yesterday and got massive problems with GPS. The GPS-location needs VERY long to settle if is working at all. I had the best conditions for GPS since i was walking outside in pretty open space with a clear blue sky....
Anyone got the same problems or any ideas what could be wrong, since i found nothing on this topic according to the matr1x kernels anywhere.
Okay. 9.0 is new, but someone must have noticed it if it is a general problem with the kernel.
the power-management is astonishing and I would gladly keep the kernel for that.
regards...

Although I have only used the kernel for a couple of hours I've found the GPS to be spot on and very quick. Some have said changing the location in your build.prop to your correct country helps?
System>build.prop

thanks. I'll give it a try if the problem reoccures. For now i just reflashed the kernel and everything works fine again. maybe TouchWake was the problem since that was the only thing i changed since flashing yesterday. I will try again and see if the gps-break reoccurres.

Does that Rom support German too?

Only three languages are included: English, Simplified Chinese and Traditional Chinese.

ah ok.
Thats a bit sad. But hopefully we will get some Rls with many Languages

ROM runs pretty god it flows compared to original color ROM! No bugs ,fcs or lags also.

i cant download

One day in so far so good. My only comment is that I had to flash the 4.2 g-apps package on top of it as the Play Store was no where to be found. Battery life seems pretty good.

This seems to a sync/update problem with google frameworks, however after a second reboot it seems to initialize correctly.

Thanks for your work.
My findings:
- I have trouble making app-folders on any homescreen.
- when moving the existing app-folder (tools) to any homescreen, it does not succeed.
Otherwise...good and fast.

Hi. Can someone please mirror the download.
Thanks

Thanks works very well.

thank, good work :good:
And you dont using any custom kernel for this ?

me too. cellular network using more power.

This Color Rom version is very smooth and working good on every functions that all I need .
But only one thing Battery life not good enough for me (cellular network & Stand by Process drains a lot Battery).
Kernel may be causing problems I guess.

Updated to ColorOS 4.2 [130808 Stable]
it now uses a custom kernel based on maxwen kernel, should reduce battery consumption.

I have a charging problem with the 4.2 [130808 Stable] update.
My charger was not detected.
Charging with the usb port from pc is ok also another carger works?

Battery drain problem

Hi guys, as I wrote in the title I have a really awful battery life with my Nexus 4 and I don't think it is related to the rom/kernel I'm using because lots of people with the same configuration have no problem. I'm currently using PA 3.99 RC2 with Semaphore kernel, but I've tried also franco and I have the same result. I started from stock rom and then i did a full wipe before installing PA, but I keep having problems. This is my situation:

I'm unable to post a log because the apps don't show it to me (I can't understand why) but it seems like the problem is related to the app I use, anyway these are very popular apps and I find absurd that to have a decent battery life I have to uninstall them because in this case I would only use the phone to call and send texts, many people are using these apps and they have a great battery life so I can't understand.

which recovery are u using? u need maybe to update it or try another recovery. I had problems with some roms, after switching to another recovery everything was fine.
maybe u give it a try:good:

I'm using TWRP, it seems strange but i'll try with CWM!

Try detecting what's using resources and keeping the device woken up with WakeLockDetector.
@mods: can't we just sticky the Battery Impressions Thread adding a 'post your battery issues here' to it's title? We're getting overloaded with battery drain threads, and the issues are common enough to have them a sticky. Thx.

I used it, in fact I posted a screen with the result and it seems that google+, facebook messenger and whatsapp are causing the issue but this apps are used by many people and they don't have problems, it just doesn't make any sense to uninstall these because I mostly use the phone for these apps :s

i9506 "s4" problem :(

my s4 "i9506" very hot and consumes the battery and the CPU,
although I give it to the factory preset
... cpu temp app : 70° !!!!!!!!! wtf !!! in january !!!!

Is the phone running a stock rom and recovery?
Have you tried reflashing a stock rom with Odin and performing a factory reset before the first boot?

yes , but Unsuccessfully

how can i know a hardware problem? or software?

If you tried reflashing a stock rom and you did a factory wipe before booting the phone for the first time, I think it is hardware problem.
How old is the phone? How old is the battery?

Is it hot when idle or during usage? Where do you usually store your phone?

+++cpu-z said (~50% cpu load ) !!!!!
please .. answer

Check whether your battery is swollen or not. Place it on a flat table and swirl it. If the battery swirls for 3 or more turns then your battery has been degraded.

I have had this problem caused by Google Play Services. Check and see if its triggering any alarms with BetterBatteryStats.
