Battery...

Hello,
After I installed ICS (JB or Stock) a had the problem, that the tab took about 80mA - 190mA from the Battery.
I'm monitoring the Battery from my HC 3.2 Overcome, and there the drain was about 20 - 30mA. So I'm not
happy with this Situation.
Then i tried the CM9 experimental from pershoot. And there i have the same low drain from about 20-30mA.
Now i want to know, why in Stock ICS the drain is 3-4 times higher than in CM9?
Can anyybody give me a hint about it.
I've tried it with a clean install, where i really only installed the battery monitor....

it seems like a kernel issue on stock ics , it keeps searching for signal even if airplane mode is on !
what i did is i installed the stock ROM then i installed a1 kernel over the stock one ..
it seems like the problem is fixed for me

Hi,
thx for your answer, but i already installed aa's kernel.
i tried from 1.59 til 1.7.
now i've 1.64 but no luck....

I think you use Stock Rom "XXLQ8" - italian ics??!!
If the answer is yes, the problem happens with me with this rom even with A! kernel.
I fix it by these steps:
1- Backup all your data....
2- Downlaod "JellyBeanRom ICS v6" from here: http://forum.xda-developers.com/showthread.php?t=1813651&highlight=battery
3- Make a full wipe.
4- Falsh the "JellyBeanRom ICS v6" as Thread steps.
5- After the tab restart and finshing falshng rom, go to bootloader and make "Wipe Battery State"
6- I hope everthing is fine now.
Or try to flash another stock Rom ver with "Full Wipe Data & system"
This is my personal experience with this issue, and this is the solution that saved me

In CPU spy you will notice that the tab doesn't go to deep sleep for long periods on ics. If you have betterbatterystats installed you will notice that this is caused by a kernel wakelock 'l2_hsic'.
I reverted back to hc3.2 overcome because I couldn't find a fix for the wakelock. But ever since calling was enabled on ics I flashed back for this mod.
I am on stock rooted Italian 4.0.4 and only installed A1 yesterday and have had mixed results so far. If it continues I will probably try V6.

@dana
i've tried all "battery drain" fixes that are here reported.
Also clean installs and so on.
I think that sxi200 is right,
because i had also the wakelock "l2_hsic"
but i don't know what causes this wakelock btw. how to remove it.

i think that's very strange....

Well maybe there is light at the end of the tunnel. I flashed Toldo's JellyBeanRom ICS V6 XWLP5 which has A1 kernal and haven't had the l2_hsic wakelock since.
I flashed straight over stock ICS without wiping and haven't had a singe problem. Tab now sleeps like a baby. Will keep my eyes on it to make sure.

I can confirm. I had the same problem and A1 solved it.

hi,
can anyone of you log with Battery Monitor Widget the mA your tab needs,
like my log posted before?
Many thx, because i don't know what i should do with that damn batterydrain....

Same here.
Flashed ital. ics over p7501 stock hc. Performance was quite nice, huge step foreward but battery drain went up to a couple of percentages per hour in the wannabe sleep mode. I took a look at it with cpu spy and the result was nearly no deep sleep! Even if my tab wasn't in use for the whole night ( only wifi turned on ) the cpu frequency stayed at 216 MHz. This results in a non usable tab for me because i wasn't able to use it a whole day at university without recharging!!
Yesterday evening I flashed A1's 1.7 Kernel over stock ital. ics and woooohooooo more than 6 hours of deep sleep last night (even though more than I had...) and battery only goes down 2 percent within this time.
From today I can tell that deep sleep works perfect until now for the periods of non usage.
BTW: A1 Kernel also solved my problem with flickering HDMI output on my TV!! Thats amazing but I'm going to post this in the seperate thread as well now.
Maybe someone could do me a favour and quote this in the official A1 thread in the developers section because due to the "10 posts rule" I am not allowed to do so..:crying:

[Q] Bricked phone :P

Hey, with all those out-dated guides I got a bit off track ;/
I've got motorolla defy red lense(in which i flashed mb526 cm10 a few months ago and it worked fine.. except phone goes blank when talking and nothing I do responds.. probably approxamity censor disfunctioning).. anyhow I tried flashing slimkat and it made my defy brick (phone stuck on M logo) , tried wiping cache and data through stock recovery no use, now I flashed following sbf DEFYPLUS_U3_4.5.1-134_DFP-231_GR_SIGN_UCADEFYEMARAB1B80AA004.0R_PDS03C_USAJRDNGIBRRTCEE_P022_A022_Service1FF.sbf
which ended up bricking my phone even harder D: (pushing the power button ends up showing bootloader and code corrupt battely low can't program message) [which probably means I flashed an irrelevant sbf with cg not compatible with my phone)
my bootloader is 9.10
oh and I have this nandroid backup back when I had stock rom (but can't recover it since I can't go on custom recovery)
any help would be appreciated!
in the meantime I charge the phone, I guess the idea is to flash the relevant sbf with relevant cg but how can I find one, and is the country of the sbf really matters?
thanks.
edit - apperantly the phone can't be charged I don't know.. it's connected to the computer/wall for quite a time and nothing changes. I don't wanna do the mcgyver method and lose my usb cable for it ;/
considering I flashed an incompatible sbf, and when connecting to computer it shows white led (when wall it won't show it will automatically open bootlader with the error.. (err A5,69,4E,00,f1), the white led ensures me the battery is loading? how can I see progress ;/
I have galaxy ace plus with a LI battery 2.7v (same as the defy) but it's bigger, should I try connecting it or it can ruin things up?

BEFORE flashing (not flushing ) your phone you MUST read carefully the reference which you surely will find in the Defy area. ALL your question was mentioned and solved here. You DIDN'T have a bricked phone and with patience you could fix it. Have a nice lecture!

You DON'T need a USB to USBmini cable. Is sufficient USB to USB cable (~1EURO) at which you cut a jack.

I took my old mp3 cable and it worked even though I was sceptic. Anyhow my defy is noticeably slow now before flashing a Rom and after (slimkat) and my antutu dropped from 4990 to 4300

Did you overclock your phone before? Maybe your OC setting is now default. Im using [email protected] with slimkat 3.0 (dalvik) and it's very smooth and stable. Only don't remember my antutu score.

by overclock you mean just changing the frequency in settings? :x
maybe the rom I used (cyanogenmod) before came with default oc?
I think mine is now 1000mhz..
what governor should I choose?

Yes, the frequency settings in Aero Control or recovery. You can try to set 1200mhz if your Antutu score is important, but you should get much more points on default settings than 4300. I've got 4740 on the clean SlimKat 2.6.
The default governor (interactive) is recommended and works fine for me.

I don't care that much about antutu it's just that it's slower than before.. and antutu is a way to show it.. i guess.
maybe the 4900 antutu was a good day for the defy anyhow I'm glad I could "revive" it and fix the annoying problem with approxamity censor that was on cyangonmod.
Thanks alot for your help

S4 Battery Issues

I purchased a extra battery just to make sure its not the battery. Battery is going down really quick. I have tried charging my phone to 100% then use a battery calibarate app to fix the issue and still not working. I was told is could be the 4.4.4 or 4.4.x roms causing this issues? I will be dowloading a 4.2.2 rom and checking it out but I got to wait for tommorow and Internet here isnt great? Any help or ideas? Current rom is "Samy Deluxe S5 Style Pick Your King" but I have tried PA 4.4.4 rom and still the same issue.

Hi mate ,
The only way to really know what is going on is to use an app like BBS
http://forum.xda-developers.com/showthread.php?t=1179809
Let it run for a few hours and check the logs to see who is the culprit

Thank you for your reply. Just found out it was a kernel issue that perviously installed that was messing up the battery. I always thought when changing roms it also changes the kernel, guess I was wrong.. Thanks anyway Rep+

High Battey drain, KernelOS?

Hi! Could anyone help me figure out why I have such high battery drain? I get about 2,5 hours of screen on time if I'm lucky. This is only on AOSP roms. According to GSMbattery it's "kernel is" that drains the most battery. I also have betterbatterystats installed but I'm not sure how the read that app.

It is a custom rom Lineage OS. What do you mean by reinstall system I've tried wiping everything multiple times but the battery still drains.

KernelOS doesn't exist, that's what i mean. every android iteration has something called a kernel, which manages the CPU and stuff. it's a part of the system, and not an OS at all. If you don't know what that is I wouldn't recommend that you poke around, you might slip up and DFU brick your phone...
By reinstall the system I mean:
-go to TWRP
-wipe system, data, cache, dalvik
-flash the A2017X universal bootstack, the modem file for your phone, the ROM, the OpenGApps if you want to have Google stuff, Magisk or SuperSU for root
-Reboot and use

Try to flash a custom kernel, and if it doesn't do anything then yeah, go back to stock

I would try Wakelock detector or look into alarm section of BBS.

I don't think it's got anything to do with wakelocks as it doesn't use barely any battery when the screen is off. Overnight it might use 3-4 percent. Over 2 hours in the day it only drains 1 percent.
I use the modem from the LOS thread and I have the G model of the phone.

Hi. Since yesterday I run dark room as opposed to RR official. I did factory reset using twrp 3.1.1.0. Before changing roms I tried to install different modems. Currently b06 since I have G version. According to stats phone does sleep yet battery drain is high. I think last night lost like 40% or even more. Not sure when this all started. I've been using RR for months without any issue. The thing is that I was always charging my phone at night so I don't know when exactly this started to happen. Perhaps there is a hardware issue. I will try to get back to stock this weekend if no other solution is found. Cheers

Z5 Compact stable ROM / Kernel suggestions / help (newbie)

Hi all
Please excuse me. This is my first foray into flashing my Xperia with another ROM / Kernel and I'm running into some problems.
I've been trying to follow various threads and instructions on this forum but keep getting stuck.
Firstly, suggestions for a stable build of something?
Generally fed up of the Bluetooth issues I've been having with the Sony builds. I used Cyanogen mod a few years ago but understand that's not around any more?
So far I have unlocked the bootlader on the Z5 compact.
I have also tried flashing a TWRP recovery to it using fastboot. This kind of works, but then I just get stuck into a reboot loop. I can get into the recovery, but not much else.
I've managed to revert back to 32.4.A.0.160 through Sony's Emma flashtool. This boots fine but doesn't appear to have any recovery function. Essentially I'm back where I started after much frustration and trawling through threads.
Any help would be welcome. Please explain things as you would to an idiot
Cheers
Jo

unlock bootloader
flash recovery/TWRP to recovery partition
flash custom kernel (stock with tobias.waldvogel's mods)
to get into recovery you turn off the device and keep volume down + power button pressed until you feel a vibration (confirmation), then you can release the power button - it'll boot into recovery

Hi,
Please you can maybe help me also, i really do not find anything useful so far,
I have unlocked the bootloader, i have a working TWRP and also Supersu. But i still have issues withe the DRM keys. My first kernel was passing most of the DRM tests (most of them, not all) but the wifi was nor working. Now i have a working one but all tests fail. Considering the fact that i even have a TA back-up can you please tell me how can i patch a kernel with my keys (not to restore TA partition, i need the workaround) or a good kernel (a stock but to work with stock fw and to be able to use the thermal control FSC and adiutor). I`m noob with Z5c and it is very different from Xperia SP (my previous phone) witch i have a lot of experience.

if stock based I use this https://forum.xda-developers.com/z5-compact/development/rom-stock-z5c32-3-0-376r2dau-t3570248
Aosp based I use this
https://forum.xda-developers.com/z5...ageos-14-1-bernis-alternative-builds-t3694904 , this rom more fast than stock. now I use this, camera quality is good also.

Hi,
Thanks for the info. I have settled to the AOSP from your link (Bernie`s). I confirm that Magisk works great with it, and all seems very good now. I had to install GAPPS from opengaps site. Hope the battery is better than Resurection .

Try calibrate your battery first, charge until 100% then use normal until drop between 5%, charge again to 100% . Use again and no need drop until very low battery to charge. I use this https://play.google.com/store/apps/details?id=com.nema.batterycalibration for calibration.
Use calibration at once only, not to much.
Your battery status must above the line inside Mv bar on battery calibration apps when unplug the charger when percentage 100%.
If 100% then unplug chager but Mv battery below than line in the Mv bar, your battery probably broken and need to change.
I also use battery charge limit to safe life time of battery.

I'm limit to 90%

Wow,
Thank you Alvian. That battery optimiser realy did the trick, it literally doubled the battery discharge time. Thanks
