Slight oddity with my Vibrant.
Occasionally when I charge the phone, it will show that it is completely charged--battery gauge will show full, About Phone will show 100% charge, all of that good stuff. When I unplug the phone, my battery gauge will instantly drop to 97%.
Additionally, for the entire duration of this particular charge, my battery life will be total crap. And by total crap I mean draining 1% in five minutes with the screen off, going from 97% to 78% in two hours with the only use being a quick check of bus schedules.
However, if I notice this 100-to-97 instant drop and plug the phone back in until it charges to 100% again, it will not display any of this odd behavior and battery life is awesome as usual, with standby power consumption at 1-2% an hour.
So... what gives?
ROM: Bionix Final R1
Kernel: JAC XMOD OC/UV/Voodoo 1.1

Dont worry about when you unplug it, its just a inaccurate reading.
It happened to me this morning with Axura, and my battery showed 97%, but the 3% was given back without me knowing, does your phone stay at the 97 for a longer time? it should, and also some people say do a battery calibration.
its like
charge till' 100
drain it to 0
charge till 100
and then on clockwork recovery go to advanced and do wipe battery stats or something
^ im not sure someone correct me if i'm wrong about the calibration.
I conditioned this battery after flashing the ROM last month. You have the directions mixed up... should charge to full, boot in clockworkmod, delete battery stats, reboot, drain to 0, charge back to full.
And no, it doesn't stay on 97 for longer than it should; as I stated in the OP, if it does the 100-97 drop, the battery life is significantly worse than when it acts normally.
I get the same thing. Actually at the moment I am trying to unplug... see the 97% and plug it back in, it will then say fully charged, I unplug it and it says 98%. I am going to repeat this until it actually says fully charged when I unplug it and then reboot to recovery and wipe the stats.
What I am confused about when it comes to reconditioning and wiping is even when the phone says "fully charged" when I reboot to recovery and wipe, once the phone has rebooted it says it's charging again. Should I leave it in until it says fully charged or unplug it after it boots?
It seems to do the 100-97 thing primarily when charging via USB. Almost every time I've seen this happen was when it was charging off my laptop.
I've noticed also that when it does this, the battery icon (I use Segmented Battery Mod) shows "100" solid without a flashing plug icon. If I unplug it, it will drop to 97. If I plug it back in and it actually charges completely, it will flash between the plug icon and "FULL."
hmm...mine does it no matter how I charge it.

Mine USED to do thar with Nero beta 3 now on Axura IRS dine I've been using it for 20 minutes and still at 100%

Updated to Nero v3 and now I have the problem constantly. It will always claim 100% charge when it isn't actually fully charged.

If you've flashed the ROM, do the "recondition" -- or if you have a stand-alone (external) charger, just charge it full, then put in the new battery and wipe your stats. (The recondition thing -- charging, draining, then charging -- is just a theory that on the second full charge you'll get "more" charge in there after a full drain -- I doubt this is true, especially if your battery stats are hosed to begin with.)
As for the dip after you unplug it -- this is just the battery manager varying the maximum charge level to optimize battery life. Laptops do this all the time -- even when they're plugged in, they'll let the machine run on battery power here and there. For a new battery it might only let it dip to 97%. On one of my laptops it has decided dipping way down to 86% is optimal. Just depends on the battery health, usage patterns, etc.
Battery life was pretty bad when I first flashed Nero, but now that I've wiped battery stats, the battery life seems much better. It still does the 100-97/98 thing, so I'm guessing it means my battery is still pretty good despite all the heavy use!
The JL5 modem seems to have worse battery life than JK6 (only very slightly though) but it doesn't get stuck on EDGE like JK6 did... net gain in my opinion.
Is it necessary to calibrate after flashing a new kernel?
Not really. I found my battery life is better after I flashed the new voodoo kernel by jt. If you do have some bad battery life, it would be suggested you do calibrate your battery.
how do you calibrate your battery also i notice after i charge my battery all nite the next morning i start off with either 99 or 98 percent any reason why???
Calibration of the battery isn't really required if you flash at 100% each time.

This is expected behavior designed to protect the life of your battery. basically what happens is your phone will charge to 100%. It's not good for a li-on battery to stay at that stress level so the phone will then allow the battery to discharge to 95%. Once it hits 95% you will start charging back up to 100% and the process will repeat. If the phone didn't do this the battery would degrade much more rapidly.

thank you some days its good and some days its bad........
After my phone charges to 100% it gets stuck at 100% and wont drain until I take it off the charger. I use spareparts to see voltage levels and it says its fully charged at 4.2 volts. After I take it off charge, battery drains rapidly to what I assume is the correct battery %. I was under the impression that battery levels go down to 96% then recharge back to 100% while pluggd in. I noticed these affects after several voltage lockups. I have tried wiping battery stats and multiple calibrationa but no cigar. Why is it that spareparts and other third party battery apps report full voltage and charge when it actually isnt while it is plugged into the wall. anyone deal with these issues?

mine stays at 100 for a while too.. But if you leave it for a long time it will say full.. Or at least it does on evil fascination.. Its probably bad battery stats.. Charge till full.. Power down.. Charge till full in power down state.. Unplug , plug back in.. Wait till full again.. then wipe battery stats in cwm.. Then use till it dies and recharge...

Not sure why, but I restarted my phone and it went from 50% down to 5 % power? Had it on the charger all night and it was still at 5%?? Took it off the charger for a few hours and im still at 5%. Tried wiping stats and had no luck? Any Help??

Drain all battery and charge it from zero. Let it be fully charged before starting it. If you run CWM you can wipe battery state.
Your question is in wrong section in the forum. Try starting the thread in General.
Cheers
+1 this -- and some additional detail...
Wiping battery stats does NOT improve actual battery life. If done properly, and coupled with a calibration cycle, it can increase the accuracy with which your battery reports its current charge. Ideal process is as follows..
Charge to 100%
Reboot into CWM
wipe battery stats under" advanced"
Reboot
Charge back to 100%
Let it DIE (go to 0%) from normal use, DO NOT charge it during the cycle
Re-charge to 100% and you're all recalibrated.
From the sound of it, don't be surprised if your phone sits at 5% for hours. After the calibration, your battery history should be a relatively smooth, downward sloping curve.

Check Settings>Battery Information>Battery Usage and see if a process named RILD is using a high percentage of your battery usage. That process - a very necessary Motorola radio daemon - is wreaking some havoc by causing very rapid battery discharge and also preventing normal charging.
No solution for you but thought I would let you know before you try too many different "solutions" needlessly.
Thanks!

I recently purchased the original LG battery charging pack with an included battery.
So i charge the batteries exclusively using the external charger. When the battery level of the phone goes to around 20-30% I swap in the charged battery. Now the problem is, even though the new battery is charged, the percentage is the same as before i switched out the batteries.
So let's say i swap at 33%, the new battery also reads 33% after the boot.
Is there a way to recalibrate the battery meter?
Found the solution:
The battery swap was done too fast, so the phone didn't realize there could be a new battery inside.
I tried again taking out the battery, waiting maybe 20 sec, then rebooted. Now the battery percentage is accurate again!
