[Q]Android-system 29% of Battery JVQ

Hi,
I recently updated my phone to JVQ but now i'm having a battery drain. The cause (i think) is the high percentage of the android-system. By now its 29% and that's alot. I already deleted the programe software-updater so that can't be the trouble maker anymore. Does someone has a fix for this?
Greetings

Yeah....let your battery go completely dead, then try turning on to make sure its dead
Leave your phone off and then plug in charger until its full, then unplug and plug in again to make sure its full
Repeat these steps 2-3 times and it should be all fixed for you
Also....using titanium backup, freeze the program called "Samsung account" that's another culprit in the "battery drain crisis"

I have already done that a few times, friend of mine has completely the same setup as i have and my battery is down twice as fast. Maybe it's the battery itself?

Is your phone rooted??

Yes, using deodexed stock jvq rom and speedmod k15-t24. Using black background screen dimmed, and everything to make my battery life the best but it doesn't make it one day. So maybe there is a bug?

Try going back to stock froyo, and flashing cfroot kernel so your phone is rooted but not deodexed or any other mods, then repeat the cycle and see if it gets better that way.

Just flash froyo and then repeat the cycle so i don't need to stay a day or so on froyo?

You'll need to be on froyo for about a week or just over, just until you've repeated the cycle 2-3 times bud

Usually doing 2-3 charging cycles does the trick (fully deplete battery and then charge until full).

[Q] strange battery behavior

I have problems running CM7 ROMs on my device. When battery is about 50%, it suddenly runs empty. When rebooting battery life is still at 48%. I haven't found an answer to that problem by searching yet. Is there someone with same problem?

here http://forum.xda-developers.com/showthread.php?t=1834028 something said about clocking down CPU and undervolting. because this stuff sounds like rocket science for me, i have not tried.

I wiped batzery stats from cwm, I calibratet battery through an app, didn't change anything...

OP you need a battery calibration:
First link on google http://forum.xda-developers.com/showthread.php?t=1616598
Googling "battery calibration android" and your O2X will tank you !

As I said, I loaded battery to 100% and wiped battery stats from CWM. But even right after the following boot I couldn't get the battery empty, because suddenly the battery stat ran down to 0, after reboot it was back to 38%.
I only have this problem with CM7-based ROMs. At the moment i'm using Modaco, battery works fine!

I flashed my device again:
- battery fully loaded
- full wipe
- wiped dalvk cache
- wiped battery stats
- flashed Gueste 3.6
Battery was at 100%. Last time I looked on the battery status it reached 26%. About 30 min later the phone was off. Turned it on again - 25% battery.
So calibration didn't help.
Any ideas....?

i did an experiment - changed my phones CPU minimum frequency to 300 mhz. it is one step from default value. now i'm testing third battery lifecycle without instantaneous battery discharging problem. You can try too

Ok, I will give it a try.
If it works I will not flush my phone in the toilet. Otherwise....

Maybe you just need to replace your battery for a new one. Batteries don't last forever, some time ago I had to change my nb battery

If anyone else has this problem: it always occurred when I had bad network connection.
I changed Baseband and RIL from 218 to 725 (v10d), didn't have a shutdown yet.

[Q] just asking

Can I know if I do nandroid restore and I should restore my battery stats.bin. Will my device be confuse with the battery life and got to recalibrate it?

No need.
Sent from my GT-S5570 using xda app-developers app

you should calibrate it only when you find your battery stats acting weird lease everything is ok

Does my device needs battery calibration?

My device battery is draining very fast so i wanted to calibrate the battery. I downloaded battery monitor and i get 4300++ when its on 100%. So do i still need battery calibration. Im planning on trying zeppelinrox battery calibration.

Battery calibration is a myth.
Will do nothing other then wipe battery stats and make a new one.
It can be done by charging the phone till 100% and disconnect it from charger

Instal good battery monitor like gsam etc. You will be able to see what is draining your battery. Also do not use full brightness all the time.
P.S. What is fast for you? Can your battery stand a day?

Its like when i leave my phone for about 2 hr. The battery drops from 70-50% on wifi. And i used to be able the last the whole day with 3g on and my phone is only 2 weeks old.

well i agree with the battery saver is a myth statement... I see you have used battery very bad way and now battery has depleted its life span. So still battery is on good side... Just try to do one charge cycle and close all unwanted apps and processes/features so it will conserve battery that way you can keep your battery safe or if you are really unsatisfied try this http://www.mugenpoweronline.com/zas...tid=5&sortby=sortid&orderby=desc&type=carrier
Good luck!
Hit thanks if i helped :good:

yes, battery calibration is a myth, so you must try install a fresh rom (try light by somin, its very battery friendly), use your brightness always low, and your wifi always off when you dont need it. you will see that your battery (if its not broken) will last for at least 2 days (depending on your phone usage)

and the best "calibration" is to drain your device to 0% (it will shutdown) and then charge it to 100% without using during charging. Do this 2 or 3 times and your battery will be very well.
this http://www.mugenpoweronline.com/zaspx/product_details.aspx?file=pr&productno=1640&PageNo=4&ccatno=5&csubcatid=5&sortby=sortid&orderby=desc&type=carrier is bullsh**

If you're rooted you should also download DU Battery Saver PRO and tick the option "low cpu frwquency while screen off'. Just that little option changed my phone's whole life style It really does work so give it a try, you won't be dissapointed.
and yes battery calibration is a myth and doesn absolutely nothing which may help your battery life (i know from 1000s of personal experiances with the calibration thing )
