OK quick question.
Right now i am in the process of properly calibrating my battery (charged to 100%, wiped battery stats in recovery, rebooted, let finish booting, unpluged charger, will let it drain to zero, then full charge all at once)
My question is, say if i do a nandroid backup within recovery of my entire rom, then wipe and flash another rom to just test / mess around, then RESTORE that backup i made with the calibrated batterystats, will the calibration still be valid? or will i have to recalibrate the battery stats again? (even though i restored a rom that had already been calibrated?)
Thanks

calibrate again
i would do calibration again.
Normally calibraton only resets data in a file so if you create a nand backup with the updated data from that file you shouldn't have to recalibrate again.
But then again recalibration only takes 2 seconds (a press of a button) if you use an app like Battery calibration
the nandroid backup will be in ur sd card and safe until u format ur sd but the calliberation will have to doine again!

Yes, I used the search bar and frankly, the thing sucks...
So like the title says, I made the backup, hit reboot system now, and it went to the logo. I gave it a good 5 minutes to startup and nothing. I decided to boot into Android Recovery and wipe cache. Still nothing.
I'm thinking I might have to sbf; Im I right or wrong?
Have you tried pulling battery and putting the battery back in with phone off and plug it to the wall charger and if you have bsr it should come up. Then you can wipe and reload your back up

How do I get onto bsr from there?
Just plug the phone into a wall charger (with the phone off) and it will turn itself on and should boot to recovery.
If you wiped data bsr is gone. Pull batt & wait 5 min if hangs its sbf time. Use this http://forum.xda-developers.com/showthread.php?t=1426062
So you can wipe data from bsr.
I just went ahead an sbf'd and re-flashed miui.

Please leave it in charge for 1 hour at least while your phone is turned off. Then start using your phone while it is charging if there is need to use it, otherwise leave it to be fully charged. Take into consideration that it takes up to 20 minutes to start charging while the phone is turned off. If after all these, the problem persists, there is a great chance that your battery is dead and you will need to replace it.

Try to take out Your battery and plug off the charger. (Wait ca.5sec) After that plug in the charger back and put in the battery. It should turn on the phone
Hello.
I have a i9100 smartphone with stock XWLSW firmware. After last change of firmware I did not even root it. So it was all stock without root.
My battery was already in bad condition - from 9 AM till 2-4 PM it gets to 15%.
But anyway.
Yesterday it discharged to 1%, when I plugged charger into the phone. I left it working, and after a while I tried to turn the screen on, but the phone was not responding to power key. It was not turning on the screen, and long hold did not turn the phone on.
I unplugged the charger, took out battery and saw a small wet spot on sticker and on battery (maybe it leaked a bit).
Well, it was not the first priority at the moment, so I just wiped it, and put the battery back, then I turned the phone back ON.
It started, but now I have a boot loop at Samsung Logo. When the battery was still discharged I could hear the discharge signal after logo, and then the logo starts again, and discharge signal again, etc.
I left it in that state for a night with charger plugged in. In the morning - it was in the same condition.
Things I tried:
Removing battery for over 10 minutes, clearing Cache from recovery.
Both recovery and download modes are working.
So the question is - can I restore the phone without Factory reset?
If not - can I somehow backup my data (savegames, etc) before doing factory reset?
I just tried to update the firmware again using ODIN with no luck. It updated successfully, but than again hangs on Samsung Logo.
Rule 1: Don't complain until you haven't tried factory reset.So be a man,and do a full wipe.

What he said. Also, flash a 3 part firmware, which will also wipe your phone & has a funny habit of fixing situations like this.
I was going to do a Factory Reset or flash 3 part firmware, but only after I backup data. That was my main point of creating this thread - how to backup data in this situation.
Anyway, I did install Philz kernel, wiped dalvik cache, cache partition - it helped, but not for long. I saw my desktop, but after few seconds it went into boot loop again. I then did a Custom backup of data only, and did a Factory Reset through recovery.
Now I try to restore data to see what it will give me.
So i have been having pretty much the same problem with some little differences.
First my battery seems OK, no leaking no nothing, but it might just got old as I've got the phone for over 2 years now... Second, my bootloop occurs after full discharge, when i try to turn on the phone afterwards it just gets stuck on Galaxy SII logo, not even the boot, and stays that way no matter how long i wait. Third, at about the last 5-8% my screen starts flickering as if it wasn't getting enough electricity which shouldnt happen too and never happend before 4 months or so.
So lastly I've been getting this bootloop every now and then. Ive got a temporary fix by backing up my phone through recovery then wiping it clean and then restoring. But i just cant figure out why it does that.... I mean wipe helps, but i do restore everything afterwards....
Without restoring the problem still occurs so its not like i restore something deffective in the sw that makes this happen...
Hello my phone was at 5 percent battery so shut down when it was shutting down I pulled battery and put in another battery that was all full. Well now the phone is bootlooping . I can get to recovery but do not want to try to restore nan droid as its old. I've tried clearing cache and delvik and that did not work any other suggestions? thank you
Few weeks ago i saw my battery drains faster than usual . it suddenly drops to lower percentages when unplugged , so i thought its time to take a battery wipe , my mobile was rooted with (Siyah-s2-v6.0b5 ) & then today i went to recovery mode and wiped battery status, .. process was completed successfully. but when i tried to restart my mobile , it shows boot animation and then suddenly stops ,
i tried data wipe , cache wipe , clear dalvik , wiping partition and installing Os using odin , but every time it shuts down after boot animation, seems to be a problem in battery but my mobile does not turn off in odin mode (power button + home + vol down ) , so i'm gonna leave for discharge in Download mode , So if you know anything that could fix this , please let me know . . Thanks.! :good:
First of all, deleting the battery stats is doing nothing to the battery life. That's a myth. But how that could damage the device I don't know. Maybe find someone with the same phone and switch batteries to see if the problem is in the battery.
