Defective thunderbolt battery?

Good Morning everybody!
I think I have a defective thunderbolt battery, sometimes when I pull my phone off the charger it drops to 95%. Funny thing this is not a everyday thing. Anybody having a similar problem like this? Sorry if this been discuss before. Have a bless day everybody...on my way to the office.

I have the same thing happen. There is something goofy with how the meter reports battery level. If you reboot your phone it drops even more.

Yea I notice that too. I seen my battery drop down 15 percent after rebooting. Is the battery defective? Or the phone is defective?

Bump charge it. Charge it all the way. Unplug, turn it off, then on, and keep charging.

The phone/battery aren't defective. I have the extended battery so I never bump charge it, but he is right. Charge it up until your charging light goes green, unplug it and then turn it off. Once it shuts down, plug it back in and will now be orange. Charge it until it's green again. Sometimes it will take a few minutes, sometimes an hour. I'm also color blind so I can never tell whether that damned light is red/orange/green. >.<

He gonna have to turn it on then plug the charger in. If left off then plugged in the phone will boot into recovery.

charge ur batt. to 100%, then go into cwm and clear batt. stats, when u turn it back on it should b around 80-85% then charge all the way back full again and then u will b at full capacity

is this all the time we have to do, I have the extended battery and it doesnt drop and I read about clearing the batterystats.bin but is this something we always have to do when we charge the phone? when I use the standard stock battery it drops with no problem

I didn't have any issues until I wiped the battery stats and now, my battery is constantly inconsistent. I would not recommend doing it as it has nothing but a pain in my arse since.
Have tried "bumping it" which essentially means to charge it to 100%, restart it, then charge it back again from whatever it dropped to.. Mine initially was around 85ish.. After a few "bumps" it crept up to 90 or 91 and then wouldn't go any higher. I charged it back to 100% and decided to follow the advice from another article which said to let it deplete to 0%.. In doing that, surprisingly it "froze" in a couple of places, I don't recall the 1st % but the 2nd % was definitely at the 28% mark. It literally sat there for a good 2+ hours with screen on max and didn't go down. Eventually it went down to 1% and I charged it back to 100%.
Issues still remain, wondering if I should've let it completely die out and force itself off?
Lesson: DO NOT MESS WITH BATTERY STATS with CW.

Where do I get into CWM, to do this?

Thanks for your help everybody! I'm sorry if this is a dumb question...what is CWM? My device is stock.

CWM = Clockwork Mod.. Goto Market, download ROM manager, then you can flash CWM. Not sure if that'll do you any good if you're not rooted though.

why when I reboot my phone like 15% of the battery life drops I love this damn phone man...i cant put it down while im at work

The battery reading after reboot is wierd.
Yesterday I was at 51% and draining are at a pretty steady rate like normal. After rebooting, it showed 41% but then it say at 41% for AWHILE.. after like an hour, it read 40% and started discharging at the normal rate.

Your battery gauge is lying to you (and it's not such a bad thing)

Thanks for the repost, I had skimmed this thread earlier but don't recall it being so detailed. Seems like the moral of the story is that while "bump charging" works, it's not really recommended as it can reduce the overall life of the battery. Wonderful, now I regret ever messing with the battery stats at all, although I can't say for sure I didn't have this issue prior to doing so.

My OEM battery wouldn't hold a charge even after charging it all day... I took it to the VZ store and they replaced it for free...... I also just bought the larger 2750 mAh battery.... works great!

[Q] Boot / Battery issue

Phone sits overnight, fully charged battery discharges from 40% to just about empty. Only in this event will the phone boot and charge as normal. Stock current rom.
Now once its on it works as normal, except that once its booted it will not power off and reboot or power cycle and reboot until it has sat for some hours.
At this point it may show a black screen, show a grey battery, show a green battery with dots under it. Unable to get it into bootloader mode without a jig.
Jig may or may not work without pulling and replacing the battery.
Flashed stock bootloaders with Odin, same thing.
Any thoughts?

Oh I did, same thing. Battery works fine in another phone.

HUGE battery drain problem

I'm using a Verizon SIII rooted with the bootloader unlocked. This problem just showed up today. I put the phone on the charger at 13% then, more than 2 hours later still on the charger my phone drops to 8%. I want to restore to from a Nandroid but I'm afraid the phone will die out before it can finish. What should I do?

Sounds like either your phone was not charging at all, your battery has gone completely bad, or your phone is not reporting the battery stats correctly. Try a different outlet? Use an external charger? Different cable?

What all have you tried? I.E. changing wall plugs, doing a battery pull that kind of stuff.

I got this phone quite recently. I hope the battery isn't bad. But the battery is charging, or at least the phone thinks it is because my red LED is on indicating the phone is charging. It may be data related as I turned airplane mode and power saving on and its now charging. I'll be able to restore to a Nandroid soon and hopefully whatever is causing my problem will go away. Anyway have any other idea what could have happened?

Well it really depends what your charging it with. If its not getting enough power from a certain outlet or power source then it might burn juice faster than its taking in.

I took this for you guys if it helps. Normally my screen is what takes the most of my battery. Now however, its the android system. Any ideas?

I got my GS3 Tuesday and i had to replace mine Friday because it was dead and wouldn't take a charge so it might be your battery.

Why don't you shut the phone off and then charge it. Then restore your back up.

Dead battery symbol? Phone wont boot

I have a regular samsung battery and an extended battery for my infuse. Throughout the day i will be using the phone and it will shut down and then flash the ibfuse charging wheel and then show an empty white battery with no charge.
I have found other posts online that say to pull the battery and when you put it back in to immediately plug in a charger and it boots up. This works for me every time however it is very annoying when it does this five to ten times a day. And it happens with either battery. Both batteries do this when fully charged.
I am getting a new phone soon and blowing this one up with a stick of explosives. But any known fix would be appreciated until then.

Have you tried wiping the Batteries' stats? I have no clue if that will help since they do it when fully charged, but who knows... It may help/work.

I have a similar problem, though the phone doesn't seem to shut down much anymore. wiping battery stats did not help. It's slowly gotten better, but far from perfect.
When the phone is on I can charge it and the phone will recognize that it is charging... but if i unplug it and plug it back in it doesn't seem to recognize that it's being charged. It's been the same on several different ROMs.
If I shut down my phone it will absolutely not start without pulling the battery and plugging in the charger.
My contract is up in May or June... As much as I enjoy all the work that's been done for this phone my particular phone seems to be getting a little long in the tooth.

[Q] Restore or Wipe - Please Help

HW/SW specifics at bottom (if it helps)
Following the instructions provided this great site I added a custom ROM last year and for 6-8 months everything worked perfectly.
I was getting two days charge out of my battery which was is a 200% improvement. I'm not on my phone all the time.
Lately however, my phone has only been charging to 90%, and now 82% and the batt. drains before the day ends.
Using the same instructions here, I restored the phone using CWM with the files listed below (which are the same files I used originally) to restore my phone.
Everything seems to be working fine but I found a bunch of old files and app links to programs I had before so obviously I didn't do a full wipe which is what I was intending to do.
Can I restore my phone by going into CWM > Wipe data/factory reset or do I have to use ODIN to go back to factory firmware (I just downloaded I727RUXLF3_I727RRWCLF3_RWC.zip) to reset then go through the steps all over again.
Pardon the lack of terminology as I have only done this twice so I'm still new to this.
I just don't know what I need to do to get it back to stock and by stock I mean the ROM below.
Thank you all in advance. Hopefully I have provided enough information.
Samsung Galaxy S II Skyrocket SGH-I727R
ICS RUXLF3radio.zip
SKY ICS 4.2E R5goo.zip
Sky ICS 4.2E-17.zip

If you want to go back to like New condition I would do the odin process. You'll have to extract the .tar.md5 file out of the zip file you downloaded, the stock rom not the sky files. User 7-zip to extract. Put the extracted file in PDA in odin. Only have the auto reboot and f.reset checked in odin.
You'll then have to odin your recovery back on.

Thanks JD I'll give that a shot.

Condition your battery for it to show correctly. Drain battery completely till it won't even turn on. Then plug it in and charge completely with it off. Once done boot phone into recovery cwm. Wipe battery stats. Then reboot.
Make sure battery is not hot to ensure a good charge after draining battery.

First off its actually hard on a battery fully discharge it. Second wiping battery stats does absolutely nothing for the battery or the android system so this tells me you have no clue what you're doing.

Weird battery problem - charging
Ok, here's a weird one, you've probably seen before but it's new to me.
I wiped my phone back to factory stock using Vin's instructions. Followed them to a T and had no problems.
Kies then wanted to update my software (now at 4.1.2) which I let happen because I was just going to wipe it again anyways.
My battery still won't charge past 80%. When turned off, it shows 100% but the second I turn it on it immediately drops to 80%.
The battery life seems to be OK so that's not a problem.
Last night I swapped batteries with my wife's phone (factory stock SGH-T989D).
Here is where it gets weird (for me).
Her phone with my batt. charged to 100% and stays at 100% when turned on.
My phone with her batt. only charges to 80%. Again, when turned off it shows 100%.
So the battery is ruled out as being faulty I would think.
My phone has been factory wiped.... or has it? Did I screw up the wipe and leave some remnant behind?
Is there something I can install that will tell me exactly what is going on?
Suggestions?
I apologize if this type of question has been asked a thousand times but if the battery calibration is a 'myth' then I don't even know what to look for anymore.
Thanks

Try taking the battery out and leaving it out for 5 minutes. While it's out press and hold power for twenty or thirty seconds. That will discharge any residual juice in the phone. Pop the battery back in and power on.

Don't know what else to try

I tried that several different times over the weekend. I got it up to 84% from 80% but now it shows 100% charged within a few seconds after plugging in the phone while it is turned on. When I pull the cable, it goes back down to 84%.
I'm thinking of wiping it again but I'm not sure that is going to resolve the problem. Don't know what else to do/try.

Don't ever do this. Draining your battery below 15-20% is actually bad for it, as the heat generated by simply charging it while idle does damage. It's also been shown that the lower the depth of discharge, the more cycles your battery will have in it.
Also, Android devs who work for the big G have said that battery stats are essentially meaningless in this generation of phones. If you do calibrate your phone, don't run the battery all the way down. Get the 100% baseline, then use it as normal.
Download the battery calibration app. I believe Skyrockets max out at 4330 mV, but I could be thinking of the Note II. If the battery calibration app shows that you're in that neighborhood, who cares if the meter says 100% or not? You're getting a full charge.

Can you recommend a battery calibration app?
I did swap out the batteries as per the post above. I was thinking of charging the wife's batt. to 100% and putting it in my phone. Then do the pull the batt. for five minute trick. At this point it's all about the hail mary.
I'll keep you posted
Update: HAHA! Just gets better and better. Downloaded two battery calibration apps. Both say to charge to 100% before operating... FML.

I use Battery Calibration. It shows the mV along with the charge level. If you're charging to 4100 mV+ when it freezes at 81%, you're doing ok. If you're only charging to 3000-some mV, your battery's borked.

Been testing a few things. I charged my battery to 83% (full) and put it in my wife's phone. It registers as 100% so it's not the battery.
Yeah, I could live with it but it bugs me as I'm sure it would bug you too!
The problem I'm running into is when I put the battery back in it goes to 83%.
I installed two battery calibration tools. Both called 'Battery Calibration' One says it can't operate until the battery is charged to 100% so I'm screwed there.
The other one says my phone needs to be rooted. I thought I had already taken care of this but I went through Vincom's steps again to root (just to be sure) and now I routinely get a "E-signature verification failed"
The CWM (ver 6) doesn't give me the option to apply from external card, nor does it have an advanced section. I think I am going to wipe the phone again and use the old CWM.
===UPDATE===
I ended up wiping my phone again, going back to CWM 5 and SKYICS 4.2. Wiped everything and voila. Battery is reading 100% again.
Thanks TJ for your assistance and patience.

Isn't it a great feeling when a potential hardware (e.g., $$$) issue turns out to be a simple software fix?
