Took the plunge and rooted my bolt on Saturday following the guide in this forum using adb. All was ok, no custom Rom, just rooted. Battery seemed to be about the same. Put the phone on charge Saturday night and was fully charged Sunday. All working as it should until Monday morning. I got the phone off of the charger and battery(2750 ma) was only14%. I freaked a little and charged the phone on the way in to work. The charge only got to around 34% and would discharge very fast when unplugged. I had read somewhere to cycle power while charging to correct errors in the reporting of battery levels, so I tried that and got different numbers every time, but not able to get a full charge.
To make a long story short, I could not get my batteries ( stock or extended) to charge. I tried imosys (forgive me if the name is wrong) on the stock Rom and even flashed the Mr2 radio and installed das bamf ginger remix without any luck. Battery would not charge under any condition. Woke up to a dead phone this morning and had to install the other battery to get the phone un rooted.
The phone is now charging as it should with both batteries.
Any ideas why the phone would not charge?
Also used 4 different chagers during the process.
you should try calibrating the battery
since you have root, you can download and run BatteryCalibration by marosige (app author shows as NeMa in the market). simple app, instructions on the launch screen.
Don't you have to have 100% battery to calibrate?
I could not get the batteries to full charge.
The Batteries were definitely discharging faster than the charger could maintain, or there wasn't any charge applied to batteries at all.
I've had mine charge at a glacial pace before and discharge so fast you could watch the percentage numbers drop just holding it in your hand for 60 seconds. Personally, I don't call a phone charged if it's on. Turn that badboy off and make sure fast boot is off as well. Even with ROMs and kernels that charged horribly, turning that thing off put juice in it in a hurry. I never had any luck getting any BAMF ROM to charge quickly, no matter the kernel I used. (I tend to use the same kernels with the same versions of android. Ziggy's for Froyo, dreamkernel for GB.) Both of those have proven to charge nicely, even if I'm wirelessly tethering the thing. I don't know what the big deal is with battery calibration and all that. I only had quirky battery charging right after I made the mistake of wiping my battery stats. Same thing happened with my dInc. I wouldn't wipe battery stats unless I had a VERY good reason, and swapping between my 1300mAh and 3500mAh battery all the time in my dInc wasn't nearly a big enough reason.
The phone was off when I put it on the charger Sunday night, and no battery left on Monday morning.
Is there a way to "undo" a bad battery calibration?
I am asssuming that when you flash a new kernel or a rom that that resets everything, At least it seems that way when I unrooted the phone.
I will probably try rooting again when I have a little time to mess around with it.

Just being rooted should have zero effect on battery charging. Next time you root, do a Nandroid backup before you flash anything (ROM, Radio, or Kernel). That's standard practice for pretty much anyone that regularly flashes.
I'd re-root, nandroid, then flash whatever ROM you want....Some of the older GB Sense kernels had a "slow charging" bug, which has since been fixed. Check out the Kernels post on the dev board, the newest kernel has fixed the slow charge bug.

Im a little fed up. Ive had the phone for over a year, and the batteries always been the worst, but lately its been even worse. I left the house at like 7:15am this morning and its 1:45 and the phone just died, and all ive done is text and have a 30 min phone call.
I hoping a couple of you can tell me what youve done to get some more life out of your battery. Ive been running CM7. Ive used Glitch kernel with it before, but didnt see any improvement at all, though i dont know what i was doing.
please help me.
When I was using CM7 my battery was terrible until I switched back to a froyo rom. I am running trigger right now and my battery lasts me all day unless I am constantly watching videos. I use my phone all day long though, from surfing the web to talking and texting and listening to my podcasts and it still lasts me all day.
Battery calibration app and an extra battery is my best advice. I bought a wall charger off ebay from hong kong for $1 it also came with 2 spare batteries that I keep charged at 100% and switch out often because I agree about battery life not being as good as one would like on GB.

HOW TO RECALIBRATE YOUR BATTERY (by heartagramm):
COMPLETE GUIDE!!!
You'll have to use the phone for about 1-4 days (although it varies depending on the phone and battery used; every phone is an individual). It runs out of battery. Yes. Let it run. Recharge. After 3-4 recharges the battery will "gain" it's performance back.
After 3-4 full charge/full drain -cycles, do the following:
1. Charge the battery up to fullest.
2. Keep it plugged in to charger, and reboot to recovery.
3. On the recovery, go advanced, wipe battery stats, scroll on to yes BUT Don't wipe them yet. When you're ready, quickly remove the battery cable and push to wipe the battery stats.
4. Reboot the phone, use normally. Let it run completely out of battery.
5. Charge the phone back to full. Turn off phone. Charge until it says 100% on the green bar and vibrates for full charge.
6. The Important Part. Remove the charge cable for 0-0.5 seconds and plug it back in instantly. Let it charge to 100% again. Do this 1-2 times again, so you've done this 2-3 times total.
7. Reboot to recovery, wipe the battery stats again as on the step 3.
8. After wiping the battery stats, plug the charger back in the phone.
9. Reboot to ROM. Keep the cable plugged in. Keep it plugged in for about 30 mins to 2 hrs. Unplug. Should say 100%, mine did for about 40 mins after it depleted onto 99%.
And this is the way you should really gain great battery performance.

i think u may have a bad battery, when i was on cm7 i didnt even calibrate my battery and i could go all day and now im running tard 2.1 froyo and i can go all day with a good amount of use and have 40% left

Just shut your data off when not in use your battery will last all day that way

Download juice defender from the market and tell me how you're doing after a few days of using it.

My phone was completely charged before I got to work. Aside from the couple minutes I used it, it has been on a USB charger the whole time. By the end of the day an alert comes on saying the phone is using more power then it getting from the charge and I should close the apps. I have almost none running and my battery meter says 70% of the use is from the screen even though it's been off 98% of my work day. This is the 2nd rom I've used ([ROM][GB][EXCLUSIVE] Thunderbolt MR4 Sense 3.0 Leak [DEODEXED/DEBLOAT]), the first being CM. I haven't done any changes to the kernel. I've had the phone for a couple days. Is it the phone or maybe the ROM?
Have you calibrated your battery? If not, try that first.
Also, I know that the usb charger is pretty weak compared to the wall charger. I think the screen usually uses most of the power normally
Although some ppl think calibration doesn't help ( http://forum.xda-developers.com/showthread.php?p=21729673), it certainly doesn't hurt.

I actually switched the rom when I got home. On the USB charger it charged real quick and since it's been off it's moved 1% after a long time. After this I recommend liquid Gingerbread 3.2 for battery life. My old Incredible couldn't hold a charge like this, granted it's only been like 2 hours but way better then what I've been used to.
I tried searching this in a number of places. I couldn't find what I was looking for, although it didn't help I had trouble using the right words to search for it with, but here goes.
I'm running CleanROM Reborn 1.1, I love it! Other info is also in my signature. Once I turned on the percentage number for my battery level, I really started to notice this.
The number will stay at a number for awhile sometimes, even when I use it, then other times it will jump several points within a minute. It doesn't drain consistently. Anyone have any insight or suggestions? It's more annoying than anything else. My battery life is alright.
I would've tried wiping battery stats, but I hear that doesn't really do anything.
Thanks.
download Battery Calibration from the Google Play Store, then charge your phone to %100. open the Battery Calibration app and calibrate it. There is also instructions inside the App if my instructions are unclear
Im going to try this but for some reason mine only go to about 96%. Never 100% lately so I am not sure if I should do it then or just leave it charged until it is 100% and hope it gets there.

Not to hijack the thread, but the phone is designed to fully charge and then discharge to 95% and then charge to 100% again, rinse, and repeat. This is to keep the battery from becoming destroyed by overcharging. Maybe that's what you are seeing, Bambino.

I've noticed this too on Ics leak roms. It sips power with screen off, then drains quickly when on sometimes and hardly at all other times. Mine just sat at 82% for the past 20 minutes, then dropped to 76% over the past five. I've heard battery calibration is bunk, but I'll try the previously mentioned app and see.
Some roms do not use a percentage because they are so inaccurate and cause the user to obsess

A little info on batteries
The important thing to remember about Lithium Ion batteries is that when you do charge them, bring them up to full charge before taking them off the charger.
They all have a circuit board in them that remembers a full charge. (If you've every taken one apart you'd see this) When you charge them this chip will restore the amount of power that has drained.
Partially charging them will screw up this function. And screw up the battery.
Deep Cycling is good for them but not all the time. Once a month is good for them.
A good rule of thumb, but not absolutely necessary is to discharge them 50% and then bring them up to a full charge. Obviously this is not always possible when playing video games or watching movies. I always try to leave it on the charger when watching movies in the cradle.
There is an app on the Market called Battery Repair. It makes an attempt to reset this chip on the battery by meticulous monitoring the charge and capacity left in the battery. Running diagnostics and setting the battery to its best state. Its the only one out there that does this.
Battery Calibration app is good if you change roms or batteries alot.
Here is what it does:
Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. This program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.
The app shows your actual battery status, and only allows you to start the calibration (i.e. removes the file) when it's fully charged, unless you force earlier calibration.
The voltage meter can be useful too. Full charge is around 4200mV.
I'm on my second LTE (first one hard bricked due to the downgrading of firmware plague).
I'm having strange behavior in the charging of my LTE. When I put the phone on charge mode (computer or wall charger)
the phone will jump to full charge within a few minutes no matter what level of charge the phone had when I plugged it in.
It didn't start out this way when I originally got the phone. The charging process took the anticipated amount of charge to get
to the fully charged state. Now whenever I plug it in to charge it takes only a matter of minutes for the phone to say 100% charged.
It is actually not fully charged but is showing that it is. If I go to TWRP 2.2.2 recovery it shows the actual charge level of the phone for a
little while and then TWRP will jump to show it at 100% charged also.
When I got the LTE from the sprint store and the service person went to activate it, it had the flashing charging light.
He charged it for a few minutes and the charging light became steady. He then went on to activate the phone. Luckily,
he was cool and didn't accept any updates and i found it had the 1.12.0000 hboot. COOL! So I ran home and rooted the phone and fed
the lazy panda. Everything was cool for a while.
I have been running several roms (MikLatTE, MeanRom, OMJ's, and Chaos) and the problem is consistent across them all. I didn't realize that you weren't supposed to calibrate the battery. I had done this several times on my OG. I had installed the battery calibration tool for root from the market and I ran it, and it seems that the problems started shortly thereafter. Battery life has been pretty poor ever since then (16-18 hours with moderate use) where I used to be able to go a couple of days on a single charge. Other than battery and the 3g disconnect issue (that everyone seems to have) the phone is awesome.
I've wiped everything except the internal storage to no avail, and without the ability to wipe the battery stats in recovery, I am lost as to what to do next. Any ideas would be much appreciated.

You shouldn't have a problem upgrading your firmware, but its probably not gonna help your battery situation. It is recommended to have the latest radio and firmware with the newer ROMs.

1. Charge over night with the phone on, then go through the whole day until the phone dies on its own, dont charge it or turn it off until it dies. this will help calibrate the battery. what may be happening is that the phone doesn't know the minimum voltage of the battery since you used the app so it is reporting the battery wrong.
2. absolutely update your firmware. i recommend the bootloader method.
3. also, HOW DID YOU GET A FEW DAYS ON A CHARGE? 16-20 is like a very very good day for me. multiple days is out of the question haha. do you like never use your phone? lol
edit: tell me if that works for you

The battery level dropped quite quickly the first two hours (-20%). I at 14.5 hours right now with 24% left.
I'll let it go completely dead before I restart or plug in. PS. I updated the firmware and radios, and all is well with that.
I have searched the forums but not found a thread which is similar to my problem.. I know there are battery drain issues with wifi etc but this is wierd and only started happening a few days back.
Basically i plug phone in to charge and it charges completely normally and quickly as it used to but only charges up to about 68/70% then it basically stops charging any higher, LED still red, charging display over battery still there. Turning phone off, rebooting, unplugging and plugging charger back in all makes no difference!
Any ideas what could be the cause of this? how to resolve?
I'm on stock JB, using the official wall charger and USB cable and i made sure the battery was full when i updated to JB as well.
Try a different battery, these are getting to the point where some will start to fail, six month warranties on batteries for a reason.
Well i have a £1.99 spare battery in atm as i run the original battery completely flat today. Seriously though be surprised if battery fail after 3/4 mths - never had battery dying issues on previous phones i've had until they were a good 2/3 years old.. Always a first though LOL
Its like the battery is saying its fully charged at 70%, now its completely flat i will charge it overnight with the phone off to full (if it gets there) and see if is resets the battery callibration or something.
Try to wipe battery stats via cwm recovery/advanced.

if you are rooted than download batterycalibration and untick 100% charge and click recalibrite and leave the phone on charge and it should charge up nto 100%

It has nothing to do with wiping battery stats. I think Kangburra is right...
UPDATE.
Shamed to say that i am not rooted yet... I have been there and done all that on my old phone ZTE Blade, but i really like the added functions that TW brings and don't suffer much in the way of anoying redraws or lag etc (although i do feel that TW could be optomised alot better along with better RAM Management)
I was going to at least root to sim unlock but got a sim free unlocked phone so had no need, then other stuff i wanted to do like freeze samsung apps etc is all possible without root and i've not come across that "I" need root at the moment.. was going to for APPS2ROM but i got no need to free up space yet.
Cheers for the suggustions though - I have that battery callibration app already (from old phone days) obviously don't work though.
Anyway - I am monitoring battery atm but it seems that running the battery completely flat until it turned itself off and charging overnight with battery off has resolved this issue - maybe this reset the battery stats and recalibrated it.
Its back to normal now, charges upto 100% as normal!! Fingers crossed this was just a blip
