After full charge and unplugging do you find that it drops right to 99% or lower? Even though it says 100% before unplugging?
Yea mine does that too. Seems kinda weird how it drops instantly

Nah, mine takes about 30 mins or so.

your battery is probably uncalibrated. mine stays for 100 for a while.
How do you calibrate the battery on these phones?
i did calibrate with batterycalibration app
Mine stays at 100% for a while after unplugging.
Charge hour phone with it powered on, when it reaches 100% unplug it, turn it off, when it's fully powered off, plug it in, let it charge when it reaches 100% with power off unplug it power back on, for the same, then use battery calibration app.
Works great for me with every android phone. (don't think you can charge your phone with it powered off if you're using cyanogenmod)

I've had something odd going on the past few days. I'll leave my phone to charge overnight and when I wake up and unplug it, it drops down to around 70% right away as soon as I unplug it, When I plug it back in, it will charge for a few minutes then tell me it's fully charged. I take it off the charger again and it drops down again to the 70% range.. It's freaking me out. I was on the stock rom when it happened. I tried wiping and starting from scratch but no dice, I installed culkins rom and the issue is still happening. I've even tried to do a battery calibration but that didnt seem to do anything. Anyone have any ideas?
Probably need a new battery since it can't hold the charge

When I wake up and take my phone off the charger, it's always at like 98 or 97%. I have battery monitor and when looking at it, it shows that it gets to 100% through charging, then goes down to 98 or 97 and then stays at that state throughout the night.
Anyone else having this happen with their phone? With enough battery issues, it seems these 2 or 3% could be an hour of standby.
When the phone hits 100% on the charger it doesn't charge anymore to prevent overcharging.. pretty common feature in most phones nowadays.. if it goes below a threshold it charges again until 100 and the process repeats

same issue... my thunderbolt use to hit 100%, but the gnex stops at 99 or 98%. if i unplug the charger for few seconds, plug it back in and boom it goes to 100%
Same issue here. Seems to stay on 99 until I unplug charger and plug it back it.

If you want to get 100% (not saying it makes a difference when it's showing at 98/99%, what volfman suggest it the best way to do it. I did it with my SGS2
it should charge to 100% in the first place. another bug that needs to be fixed... hopefully the 4g gets fixed first cuz with this, i can live with.
The reason i want `100% is cuz its nice to see the 100% rather then 99%.
I'm on FB17 and my phone is getting really hot while charging is stuck at 99%. It's been like this for a couple hours. anyone know what's up?

Is something running? When you're plugged in, you're still running off the battery. Mine only goes 100% if it's in standby while plugged in.
Nothings running at all

Turn off the phone and let it charge.
If that doesn't work, pull the battery and let it sit for 2 minutes
Yeah, I'm having the same issue. Also read a few others were as well. I'm going to try and recalibratey battery. Ill keep you posted.
+1 to Nibrs' comment. I would shutdown the phone completely, let it take a full charge WITHOUT the android OS running, unplug the charger, remove the battery for a few minutes then boot the phone back up. After it's been up and running and settled in, plug the charger back in once again. It could take 30-45 minutes to finish this last trickle charge.
I've had this issue since cm9 alpha 1. Don't really care.

Thanks for your non-contribution to this thread.
Alright, are calibrating didn't work ( might of helped battery life tho) it charges to 100% only when my phone is off. As soon as I turn it on, its at 99%. I miss my blue led.
Sent from my SPH-D710 using XDA
Mine will be stuck on 99% for a long time also but mine will eventually say 100%. It has to do with how the battery is charged. Once it gets to a certain point it only does a slow trickle charge to maintain the battery level. So for the 99% part it's supposed to do that but you shouldn't have those heat issues. Did you flash a new ROM recently by chance?

Since GB my phone has done this same thing. I just figured its an ICS thing...really if u think about it, ur phone is at 100% while charged...u unplug it and it is using battery so you're at 99.999 percent off the bat...seems like the phone just doesn't round less than whole numbers.

You're not actually fully charged when you unplug it. It would be in the 90% area because it doesn't constantly charge the battery. It stops once it gets to a certain point and then will start charging again once the battery hits a certain minimum level.
Well, took almost 12hrs of charging but finally got to a 100%. Btw. I'm on blu kuban rom. Not sure if its a ics bug or a battery issue. Never had this happen in stock.
Sent from my SPH-D710 using XDA
I think it is supposed to float between 95% - 100% to avoid damaging the battery.
Sent from my SPH-D710 using XDA
Don't know if this a factor but had this happen today on ff09. Battery jumped from 54% to 10% on one reboot (phone was hot)... Rebooted again and back up to 26%.
Got home, plugged in on LG cord to 99%. Changed to Sammy charger, finished 2 hrs later.

How many cycles have you gone since flashing? I have been on blu kuban for over a month now. I update the instant I see an update. Most times it takes around 3 full battery cycles before I see decent life. This last update seemed to take longer than usual to see normal battery behavior. First I would try draining battery to 5%, run battery calibration script in the updater then fully charge and calibrate again. If it continues I would recommend the standard restore to stock and reinstall.

So, my battery will charge to 100% and when I unplug it, it stays at 100%. Thing is, with the battery still showing 100%, when I plug it back in, it drops down to 99% and keeps charging. I've switched batteries, pulled batteries, deleted stats, etc. and it still happens. Any ideas or suggestions?
Thanks

Why would you plug it back in anyways if its already at 100%? Does it affect your overall battery life? If not don't worry about it.

Because when I'm sitting at my desk at work I leave it charging. And yes, my battery life is pretty ****ty lately.

When the phone is charged at 100% it obviosly stops charging but it still displays full charge, so when you unplug its actually discharged a little since it hit 100%.

Right, but it drops to 99% when I plug it back in. That shouldn't happen. It has never happened before, even when GB had charging glitches.

Theory:
When your phone is unplugged it uses the upper register during the battery drain until it meets a point where it changes to the next number. So after you unplug and your phone is draining battery it will still read 100% even though it is really going 99.9...99.8...99.7... until it reaches the defined lower register (any chosen spot not necessarily the next whole number) and then shows 99%.
When you plug your phone back in it uses the lower end and counts up. So even though when you unplug for just a moment and the charge is at 99.999% it reads 99% to let you know it isn't fully charged. It is charging that little bit.

My wife has my old S2 and the past day has noticed it only charges to 52%.. She tends to play on the phone doing miscellaneous stuff thru the day and when it gets low just plugs the charger in and continues to play.. I know on my S3 everynight I allow it to get down to about 2% then will plug it on until it reaches full charge 100%.. Should I allow hers to fully discharge til the phone shuts off and let it get a full charge cycle the next couple days iin hopes of "re-training" the battery cycles or is there something else I should do.

Lithium battery's don't have a "memory" like nickel cadmium batteries. They would die quick doing what your describing over time. Lithium doesn't work that way.
In other words, I wouldn't worry about it.

Method 1 – The Drain Way
Drain it down until fully dead.
Charge normally to full.
Reboot to Clockwork recovery and wipe battery stats (under advanced, on second page), reboot phone.
Turn everything on, flashlight, Bluetooth, Wi-Fi, Pandora, the whole nine, to quickly drain it completely dead.
Charge normally to full.
Method 2 – The Powered Off Charge way
Charge your phone 100% while it’s on.
Unplug it from the charger, power off, then charge it up to 100% with it in a powered off state.
Unplug charger from phone. Power it on, and then charge it to 100% while the phone is on.
Unplug the charger and then reboot into Clockwork, go to advanced and clear the battery stats.
Power on, charge to full, and then enjoy.
Method 3 :
Start with the phone powered on.
(Phone on) Charge battery until the LED turns blue
(Phone on) Unplug the phone from the charger, wait until the LED turns off
Power off the phone.
(Phone off) Plug the adapter into the phone, charge it up until the LED turns blue
(Phone off) Unplug, wait until the LED turns off
Power the phone on.
Wait until the phone is booted back up all the way, and then power it off again
(Phone off) Plug the adapter into the phone, charge it up until the LED turns blue.
Boot the phone into recovery mode
Go to Advanced, and then choose Wipe Battery Stats.
Power the phone on and use normally.
You really dont have to reboot into recovery and wipe battery stats as that doesn't really work but to get all your juice back its going to be a few cycles also this works pretty good as well https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en
