I am trying to calibrate my battery, so I fully charged my phone and wiped battery stat (the recovey didn't return "installation complete" when I selected wipe batstat...is this normal?), and turned on to let it drop until it shuts of automatically.
But at about 96%, my phone rebooted automatically while using google voice international call. Do I have to restart the calibration or does it not matter at all?

You actually wiped nothing. CWM doesn't wipe your battery statistics. You need to download Adynalyne's scripts to do it, OR if you're on one of the newer Super Clean ROMS, just open a terminal on your phone and type in:
su
bstats
I believe that's it anyway.
Or flash this the same way you would flash any rom or kernel in cwm.
I am on sc 2.9.1 with voodoo kernel. I will flash that file and see if it worked. Thank you!

Or you can manually delete the file "batterystats.bin" located in /data/system

Does wiping the battery actually help battery life, because if so, how. I'm getting about 14 hours outta my phone right now.

Did you follow these steps? I am running Bionix 1.7 w/Voodoo and used these steps to recondition my battery. I would say 14 hours is pretty good. These phones are battery whores. What apps are you running? GPS on all day?
Battery Reconditioning:
1. Charge phone completely, leave plugged into power
2. Boot into recovery
3. Wipe battery stats
4. Reboot
5. Remove power cable
6. Drain that sucker all the way
7. Recharge fully
8. Rejoice!
Question about step 3 is that clear cache from the recovery menu, cause I can't find the wipe battery stats option....
I have:
reboot
reinstall packages
clear user data
clear cache
You want to boot into Clockwork Recovery and then look under Advanced.

I can't seem to figure out how to actually get into clockwork recovery without installing a rom or backing up a rom through Rom Manager. Could you please tell me how to get into the CWM Recovery instead of the Vibrant Recovery?
Thanks for the help in advance

With CWM you have the option to boot into recovery. If you get to vibrant recovery then just choose the update package option and that should transfer you to CWR.

thank you, I was now able to get into the advanced tab and see the wipe battery stats.
I thank you so much ur a scholar and a gentleman!
you may can't believe. my battery life is up to 25 hours...i may use less than others. but it is very long anyway..

Do I need a rooted phone to do this?
Yes. You can't install clockwork recovery without root.

Do you mean to choose the "Reinstall Package" option? I don't seem to have a "Update Package" option in recovery.

I have done this about 20 times and I get the same battery life every time 7 hrs max and that's texting and some internet browsing on edge since 3g is week at work. So I don't what I am doing wrong or if I just have a crappy battery but I don't know how you all are getting that kind of results lol. Oh and I got my phone used from a friend so the battery could of been broken in improperly so that could be why it does nothing for me. Any suggestions any one?

So like the title states I'm having some difficulties flashing a rom. I just updated to froyo 2.2 with root and I'm trying to flash nero v5.0. The problem I'm having is when I boot into clockwork i keep getting an E:can't open /cache/update.zip. I've tried both method 1 and 2 from here http://forum.xda-developers.com/showthread.php?t=732458
Did you make sure to take step 2 on the tutorial? "Flash clockwork recovery"?
If so, I would try it again to see if it helps. Another step is to uninstall ROM manager, then re-install it taking all the steps again. It sounds like you may have accidentally deleted the update.zip file that should be on the root of your SD card.
yea, i tried it. I flashed it. I even clear the data and uninstalled rom manager and reinstalled. I also never touched update.zip as well. This was the first time I've actually mounted my phone to my computer and opened up my internal/external sdcard.
OP, here is a thread I made for issues in the past.
Try this and let me know how it goes:
http://forum.xda-developers.com/showthread.php?t=875890
still no luck, i boot into recovery and get the same message still
Well, Hmm... You could try the steps in the noob guide and use ODIN to install froyo+root. This is the ALT METHOD in the guide. This is what I personally use.
Not really certain what's going on man, but doing this can't hurt.
I recently followed your guide, I could try again it wouldn't hurt my phone right?
No, you are not going to hurt your phone...
lets troubleshoot.
List to me step by step what you have done... If need be I will ODIN to JFD tonight and we can go through it together. I'm certain it's something silly though. No reason it should not work. You have a a Vibrant on T-Mobile right?
yea i have a tmobile vibrant so this is what i just did right now.
1) Flashed froyo+root from your noob guide followed all the steps (i.e. wipe data etc)
2) downloaded rom manager and flashed clockwork recovery.
3) placed nero v5.0 into the root of the phones internal sdcard.
4) went to rom manager and roboot. E: Can't open /cache/update.zip
(Bad)
Installation Aborted
nvm i think i got it to work
Do i need to do anything special for the longer battery life for nero v5.0
^^ what was the issue?
^ nothing special... you may want to recalibrate your battery. Drain it down to it powers off on its own (or really close)... charge it full... leave it on maybe an hour longer after fully charged... you can bump charge it (DO NOT do this a lot)... all this means is once full, unplug and then plug back in... your "full" battery will accept more charge....
dont boot up, but go straight to CWR and then Advanced > Wipe Battery Stats
reboot with the power cord still connected. Once its booted unplug and use like normal.
I repeat, do not bump charge often, this will hurt your battery.
I just flashed froyo again and used the update zip on the fix thread

hi, so i recently upgraded from westcrip's RRemix 1.3 to 1.4 and suddenly my phone wont charge beyond 98%. i tried to enter recovery and delete the battery stats but still the same any ideas? thanks
Try flashing the kernel Siyah 3.1-rc5. With this kernel there should be no problems. Just install from CWM recovery, wipe your dalvik cache and reboot.
If you are happy with your kernel, download Battery Calibration from the Play store. Plug your phone in a charger, wait until it is fully charged (or 98%) and calibrate your battery stats.
Hope this helps

I take out my battery when it happens and put it back. In after a min or two and charge it again. It'll go to 100%

I have JXD s7100B with Android 2.3.4. After rooting it and killing cell apps (and all unnecessary apps) it's battery lasted about 4 hours and it was OK. I used Battery Calibration from Google Play to try and get some more and after that it started acting weird: It could not boot (it would loop the bott screen) unless it's on the charger. After it boots it would drain the battery in less than 20 minutes! When I try to charge it it would charge to full in 10-15 minutes but when I disconect the chatrger, it will again last <20min.
After a few days it started acting normaly (booting and battery life) but few days after that it started the same again:cannot boot unless on charger and lasts <20min. I tried recalibrating battery again with Battery Calibration, reflashing firmware with custom rom and with original rom from the manifacturer - nothing. It still acts the same.
Once, while using bitrider's custom rom (I still can't use URL's ), I booted it and got black screen with no icons nor drawer (i guess launcher crashed) but with only the notification bar (battery level notification, working clock) and touch screen not working. I left it like that to see how the battery will work and it lasted normaly! After that I experimented with two original firmwares from the manifacturer and it drained battery fast like before. If I start JXD in restore mode battery lasts long there too.
So my guess is that battery is OK but software somewhere in Android is reading baterry level of 100% as 100% but of 97-98% as 15% and it forces power off although battery has juice to power the tablet. Is there an app that can tell to Android how to see battery or could I do it by editing the firmware somehow. Enything to make it work like it did.
Do you have a custom recovery? If so, I think there is some way to delete the battery configuration files from recovery. You charge the device until it says it's full, delete the files via recovery and then boot normally again. Then the OS will regenerate the files.
This is the same thing Battery Calibration should do, but maybe it's doing it wrong or something.
It could also be that you have some app that is draining the battery. This would explain why the battery lasts longer when no apps launch. Install BetterBatteryStats from the market to see if some app you have insalled is causing wakelocks (these drain your battery a lot). It is a paid app, but if it fixes your battery life, it's well worth it. You should probably try this before the other thing with the recovery.
Thanks for quick answer

Did that and nothing changed . I charged it to full and used Root explorer to delete batterystats.bin in /data/system and OS made another one but it did nothing.

Done (on your advice): nothing on the lists last longer than 20 seconds (I've just turned it on and let it drain). Application doesn't explains why I can't start it without charging it, why, when I deplet it, I only need to charge it 10-20minutes to full and why it happens on three diferent firmwares (Theoreticaly, maybe the same firmware - one on english, one on chinese and one made from chinese, but that chinese (original) worked normaly before Battery Calibration).
Well, apologies for making you waste money on that app when it didn't help then
Have you tried reinstalling stock ROM after doing a wipe in recovery first and just starting all over again?

I've reinstalled stock ROM a few times but I didn't do wipes. I just did it one after another. I'll do a "wipe data/factory reset" from recovery mode and then install stock ROM. I'll post here what happened.

That might be the problem then, I believe installing new ROMs without doing a "wipe data/factory reset" can sometimes cause issues.
Same . I've done data wipe/factory reset from recovery mode (it has nice "are you sure" screen 7 "No"s + 1 Yes + 3 "No"s) and then installed stock chinese ROM but again battery starts draining 3-4% per minute. Is there a partition in Android that doesn't get wiped with factory reset?
The system partition does not get formatted when performing a wipe "data/factory reset". Can you check to see if you can format the system partition in recovery?
That's an interesting information. I'll see if I could format it somehow. Options that I have in recovery are:
-reboot system now
-apply update from sdcard
-wipe data/factory reset
-wipe cache partition
-wipe media partition and
-reboot into factory test
Has anyone ported clockworkmod recovery for your device? If so, that recovery has the option to format system. Has someone created an all in one wipe that included formatting system for your device?

It sounds to me like your battery is actually faulty. Try another battery, or put yours in the freezer for about 30 min, then charge.

Fixed it!!!!
User named Friend on the apad forum posted that he found somewhere how to fix this issue and I tried it and fixed it. Thank you all who tried to help me - it is nice to see normal, helpfull people on the net. Thank you very much. Here's how I did it with the image for an easier orientation: goo.gl/XpC5I (can't post urls yet but this works. It leads to apad forum where it all started). All the best.
Glad you were able to fix it and good luck with your tablet. Hope everything goes well.

This is my vote. Get updated version of the ROM or same one. Flash using recovery.
Same problem even after flashing a different rom
