So,
I've flashed three or four ROMs over the last week (with a few different kernels) and they're ALL having the same issue:
I use the "miagi method" to fully charge the battery, but when the phone is ON, the blue LED comes on when the phone is still reading 83%. I turn it off, plug in, and after a few minutes it's at 100%. I've wiped stats, flashed ROMs and kernels and the problem persists.
I don't know if this is having an actual effect on battery life, but it sure is annoying.

I'm going to assume you've been to this forum?
Personally, with all the phones, re-roots, re-flashes, and Odin flashing I've done I've had no need to do any battery edits, so I am limited on experience. My question to you is this: Does it hang at 83% for a while when in use, or does it immediately begin to drop percentage as if the battery never charged beyond that point? I know that sometimes after a reboot, my phone will go from 50% to 20%, but then hang at 20% for hours since it is in actuality at 50%.
If none of that helps you at all, my suggestion is this. I found the same thing for half the cost several months ago elsewhere if you look. It came with 2 batteries, one for me and my wife. The included batteries are notably not quite as good as the original samsungs. However, carrying an extra battery gives flexibility, and the wall charger does a faster and more effective job at charging any battery.
Plus, then you'll have a battery while you're other one charges!

++ on This .... I've used that calibration method (the 2nd one, off method) and it worked well for me.
hi i can solve this just follow simple steps
discharge your battery upto 17 percent
than use back camera with flash on take pictures with flash your phone will power off suddenly after 2 to 10 pictures.
just plug in charger issue is resolved your battery will be charged upto 100 percent

I'm surprised that nobody is mentioning the poor battery performance on the tilt 2.
I'm at 50 percent already with 8 hours standby (sleeping) and 2 hours of work.
I have my email update after every 15 minutes, and bluetooth on. No wifi.
Is it just this device or the ROM. I'd rather not say the ROM to implicate, but can we get an honest evaluation from Touch Pro users about how long their batteries are lasting??? Please.
hi, battery calibrations are lost when flashing roms. It is said to take a full discharge and full uninterrupted charge to restore these calibrations which cause reduced battery performance and also using the phone for a few days also helps too. I admit I would like to see better battery life generally, but its the price we have to pay for such a feature-rich amazing device.
Things like Lumous (auto back light software) can help out controlling how bright the backlight shines in certain scenarios. Setting backlight to switch off after 10 seconds and device to sleep after a minute can help out too along with not having 3G connected when not needed as with data connection, bluetooth, wifi etc.
Hope this helps out.
in regard sto battery calibrations, I have done that, and i have been with the same rom for 5 days
hmmm yeah I do know what you mean though about the performance of it, perhaps invest in a new battery, an extended one maybe? My TP2 lasts on average 2-3 days with some music playing, weather updating, not much calling, alot of texting and maybe some internet use.
same battery issues here with 6.5 stock rom but after hard reset
battery live is 30 hours with stil 2 stripes on batt indicator
pres green-red button-powerbutton read the message and then volume up.
Oh and I think the first battery loading is done 2 quickly the green Indicator after 1.5 hour was green < hold the device loading for 4 hours
yea i always perform a hard reset after flashing a new rom, i personally find the full discharge and recharge a good way to get things back to normal. However currently experiencing a max reading of 99% despite green light and it stopping charging. Have let it fully discharge until it turns off, and then left the device in bootloader to make sure the battery is completely dead and left it charge overnight but yet still only get such a reading. Perhaps when I flash an updated rom the reinstall may restore (which won't be too far away I'm sure, loving the Cell Pro series, thanks Sergio!)
There are a lot of reasons for the battery life to go down quickly. I have used many different ROMs (mostly cooked ones from the chiefs here) and have not found a lot of difference in my battery performance. It has been noted somewhere on this forum (room-mate read it somewhere here) that the stock radio on the tilt2 seems to be best battery life for most who have used it.
So to sum some things up:
- Version of radio
- how bright the screen is kept at all times
- number of applications running all the time (including auto updates for stocks, weather, push web pages, etc.)
- Temperature (going from a warm house to the cold outdoors)
- speed of processor
- size of screen/resolution
can all lead to shorter battery life.
Living in a rural area vs. downtown in a major city can also greatly affect your battery life. Most buildings will have cellular devices attached to them as companies receive some money from cellular companies for hosting their equipment. So battery life is much better downtown as the phone does not have to search as much for a lock on a good signal.

Never fully discharge the battery! Most all devices will use Li-lon batteries and when over charged or fully drained you can kill the battery. Most devices are intelligent enough to charge up to (approximately) 98% and only let the battery drop to no less than 2% of life before shutting off. I used to do support for HP notebooks, and when they introduced lithium-ion batteries, people would demand a new battery when it would not charge past 98%. This made them change the way the software was reading the battery to reflect the 98% to read 100% on a full charge.
There is a good link in the wiki for our phones... I'll give it free of charge this time: http://forum.xda-developers.com/showthread.php?t=519673

thanks for the info, will give that wiki a read!
Man, I hate starting new threads! I did a simple search and couldn't find this problem anywhere else, so here goes:
Earlier in 2009 I bought an extended 2400mAh battery for my Kaiser (8925). Everything is working just fine, except that I noticed that the phone doesn't seem to notice that the battery life is much better for this new battery.
What I mean is: after a few hours of usage, the battery level drops at a normal rate.
Once the phone tells me the battery is almost dead (and sometimes the phone will shut off if I ignore this), I can shut down the phone, remove the battery, wait a few seconds and then replace it and boot back up the phone.
At this point, the phone will usually tell me that the battery is at 33% to 36% charged. Notice that I did not charge the battery, I just removed it and put it back in.
When I first got the battery, I cycled it completely three times in the phone, removing it twice and replacing it to ensure that the battery was completely drained before charging it to 100%. (Yes, I know that is only recommended for metal-hydrates, but I feel better doing that anyway).
On the top-end, it usually takes about two hours to charge the phone from 30% to 99% via a standard USB2.0 connector.
However, the phone will report that the battery is not fully charged for nearly an hour after reaching 99%.
I know what you are probably thinking; Why is this guy complaining about his battery performing better than his phone reports?
Well, it IS kind of annoying. I would like the phone to properly report the remaining percentage for my own benefit. I really hate having to guess at how much time I have left before I need to drop it off at a computer or wall outlet while I find something else to play with for three or four hours.
So... Does anyone know how I can convince my phone that the battery is pretty awesome and to start reporting the actual battery life?
Something I've discovered recently, and I am not sure I can explain it properly, but here goes...
I am running SRF 1.1.1, I don't believe this is the cause of the problem, but probably something that should be stated.
So running SRF1.1.1, I usually get wonderful battery life. I typically use an external charger and swap out batteries when they get to around 10-15%. This has worked well for me.. For the past few days I got lazy, and just plugged my phone in and left it on my desk to charge, no problem. When the battery is fully charged and I unplug it from the charger, I noticed it was rapidly draining.... I am aware that often when charging via the phone the battery immediately drops to 96% when removed from the charger. So this is normal, but I've noticed that after unplugging from the charger I lose about 10% per hour, when normally it may be 1-2% depending on usage.
To remedy this problem, rebooting seems to fix this issue. I have also had success with the airplane mode toogle. I don't see any odd usages showing up in spare parts, but is there any other way I can test this theory?
Thanks!!
Edit: Wanted to add, that this only seems to happen when using the charger cable with the phone. Swapping batteries does not seem to produce this issue. It is only when the phone is removed from the charger.
I haven't calibrated by battery lately and thats exactly what mine does too, I would stick to the external charger because our phones charge excruciatingly slow unless off. Try calibrating by charging to full while on then turn it off and let it charge more and repeat that a couple times then boot into cwm go to advanced and clear batt stats
Is there an advantage to calibrating a battery if it is not being charged in the phone?
This is the TWS bug mixed with no battery calibration.

similar to what i have been experiencing. i enjoyed great battery life with srf 1.1.0. have a 3500mAh battery that i used to get about 48 hours out of, but now it is averaging around 25-30. i do not have anything but the stock battery to swap with, so i do put it on the charger nightly now. i was planning to recalibrate the battery tonight to see if that cleared things up.
what would be a way to fix the tws bug?
I have noticed this too. It seems to srf seems to not like my extended battery. I am lucky I get a day out of it. I some times will plug it into one of my work computers just to bring the charge up a little and it starts flashing red and discharging this is only on my extended battery not the 2 stock ones I have. I have even tried different kernals to see if that was issue it isn't.
Sent from my lean mean drunken machine useing XDA Premium and a 12 pack of Sam Lager
in looking at battery usage in >settings>about phone>battery use>cell standby i see usually 0-5% tws.
one thing i have noticed, though have not tested is that the screen appears brighter, even at the minimum setting than what i remember from srf 1.1.0
Problem:
I have been reading as many posts as possible but I haven't come across my exact situation. I apologize if this is posted elsewhere.
I am running a rooted Dinc using CyanogenMod 7.0.3. If I charge the phone while it's powered on, the amber led turns green as soon as the battery indicator hits 100%. However, recently I've noticed that if the battery is close to being full, say 90%, and i power it off to charge it, it actually takes longer for the amber led to turn green. It might take 20-30 minutes longer.
I've also noticed the amber light turn green when the indicator only showed 92%. In trying something different I also noticed that if I charge the phone while it's powered on, then turn the phone off, the led goes amber and takes another 20 minutes to turn green again (I might be accidentally bump charging in this example but I'm not sure).
Attempted Solution:
I've read that a battery recalibration might help. I tried one method that requires the battery to be pulled after a full charge, but my phone won't boot while plugged into the wall if there's no battery. Then I tried booting into recovery, where I found an option to reset the battery stats... which I just did about 5 minutes ago.
I'm going to see how things go tomorrow, but is this normal? Has anyone else experienced these things? Thanks.

The kernel and the hardware charge it in different ways. That's why there are differences. DInc is famous for ending charging before the battery reads full. There's already a thread on that. there's not much point in getting hung up on how that thing charges. Be glad yours isn't like mine; a battery that discharges faster than it charges. Seriously.

Before I had a fast charge kernel (thanks Chad!) Using GPS with the stock VZW car charger, my battery would go down while it was on the charger!
Sent from my ADR6300 using XDA App
On AOSP roms, the LED will turn green at 90% and charge slower from 90%-100%. Perfectly normal, and I think on any rom it will charge slowly from 90%-100% to protect the battery.
The battery will charge further when you turn the phone off, what you described is what's known as bump charging. If you do this, you should notice a slower drop from 100%-90% than usual, because the battery is charged to a "true" 100%. When the phone is on and charging (above 90%), it simply keeps the battery above 90% even if it says it's fully charged, and this is why the inc is notorious for the quick 100%-90% drop.
If you do a bump charge and then clear the battery stats and use the battery calibration app will you need to bump charge again or will it know what the true 100% capacity is and keep the droid lasting longer. Not noticing much of a diffrence when i went from 1300 battery to a 1500. May get a bigger batter that'll fit the stock battery door cause I'm trying to get the best battery life i can get.
Thanks guys, I appreciate the help. I think something else that has thrown me off is that before I rooted the phone I wasn't able to see the actual battery percentage in numbers... all I could see was the battery icon. Things are now making more sense.
After recalibrating my battery I bump charged the other day and I was able to get almost 2 days out of my phone on light usage. Without bumping, I was able to end my day yesterday at 50% under my normal usage. Which is a noticeable improvement. Normally I end the day with about 10-20%. The big test will be once I go back to work next week. The cell reception is real spotty in my classroom, which I know makes the cell radio work harder.
Thanks again.
I found a lot of answers I was having about battery charging in this thread:
Your battery gauge is lying to you (and it's not such a bad thing)
So, I bought another battery. Will this sort it?
Also, what's the usual procedure?
Should I charge the battery to full in the phone (turned off) then boot, set up, then charge again and reset battery stats?
The problem is that the battery control chip doesn't take into account that the battery ages.
Resetting battery stats or charging while turned off will only clear the stats you see in the settings menu. This guide will make your battery drain to 0% again: http://forum.xda-developers.com/showthread.php?t=1534892
I don't know what a new battery will do though.
I gathered that, but as the phone is going to a new user (my stepson) we got him a new battery anyway
I just wondered what the correct procedure is. I know you need to do a first charge with a new battery, as with a new phone, however, this phone obviously has a working ROM already on it.
So, the phone is charging now, switched off. Should I turn it on, use a little, then use the battery calibration app to delete the stats and then drain to 0%?

Well, that assumption is probably inherited from the NiHM batteries in the past, because it's not needed with Li-Ion batteries. In fact charging to 80% is better than charging to 100% and keeping it plugged in.
You can read more about it here and here.

Just charge it and use it for a full cycle. If it shuts down at 15%, you can try the battery calibration from the thread I mentioned above. If it doesn't, you're battery capacity is the same as the one the battery chip has calculated, which is good.
So, why does the first charge take so long?
This thing is still charging and it's been on the charger for 3 hours, whereas usually it'd be charged fully by now.
Been like that for every Li-Ion battery I've ever had (including my S3, took around 6 hours to charge, usually takes 3).
EDIT:
Just to clarify, I don't intend on leaving it past the green light. As soon as it says it's full I'll be taking it off charge and not trying ot overcharge it. But I still have the orange charging light after 3-4 hours.
To be honest, I don't know. Maybe it's a safety to prevent overcharging. Coincidentally, I've got exactly the same issue now. I asked about it in the calibration thread. I suppose it's normal, but I'm not sure about that.
