There have been about eleventeen thousand questions across multiple threads on how to calibrate the battery properly...figured it probably should be a sticky in here if possible.
You have to know how to get into Recovery mode. You can do this with Quickboot when the phone is on, or the powered off phone method:
1. Power off phone or pull battery and replace.
2. Hold all three of these buttons down: Vol-Down, Camera button (lower left as you look at the phone) and Power on button).
3. You will see a small graphical menu come up. Most of us are using Clockwork, so I will focus on that - it will be a green menu.
For the battery wipe, Go to Advanced, navigate the menu with the vol up/down keys, and select using the camera button.
There are three ways so far:
The Drain Way:
1. Drain it down until fully dead.
2. Charge normally to full.
3. Reboot to Clockwork recovery and wipe battery stats (under advanced, on second page), reboot phone.
4. Turn everything on, flashlight, Bluetooth, Wi-Fi, Pandora, the whole nine, to quickly drain it completely dead.
5. Charge normally to full.
The Powered Off Charge way:
1. Charge your phone 100% while it’s on
2. Unplug it from the charger, power off, then charge it up to 100% with it in a powered off state.
3. Unplug charger from phone. Power it on, and then charge it to 100% while the phone is on.
4. Unplug the charger and then reboot into Clockwork, go to advanced and clear the battery stats.
5. Power on, charge to full, and then enjoy.
Third option (thanks squshy 7), I paraphrased it and wrote it out a bit for ease.
Maybe we can call it the Mr. Miagi Charge way....aka Power On, Power Off, Charge On, Charge Off way lol
(the parentheses are the state of the phone)
1. Start with the phone powered on.
2. (Phone on) Charge battery until the LED turns blue
3. (Phone on) Unplug the phone from the charger, wait until the LED turns off
4. Power off the phone.
5. (Phone off) Plug the adapter into the phone, charge it up until the LED turns blue
6. (Phone off) Unplug, wait until the LED turns off
7. Power the phone on.
8. Wait until the phone is booted back up all the way, and then power it off again
9. (Phone off) Plug the adapter into the phone, charge it up until the LED turns blue.
10. Boot the phone into recovery mode
11. Go to Advanced, and then choose Wipe Battery Stats.
12. Power the phone on and use normally.
Still a noob, but what would exactly need you to have to Calibrate Battery? Also what exactly does it do for the user?
P.S I'm sure I could look this up but it would be nice to see it in your thread for others to see

Well it's really a matter of semantics...you're not calibrating the battery, per say...it's actually calibrating how android is reading the battery. (these phones use Li-ion batteries, which don't use memory, so they themselves never actually need "calibrated" like some older types of rechargeables)
But...as far as what this means to you, its kind of a big deal! It improves battery life in letting android know when your battery is actually at 100%. When flashing new kernels and ROMs, its very likely that the phone will read your battery at full, when in reality its probably less. So it would seem like your phone isn't getting as good battery life (when in actuality it just hasn't been charged fully but you don't know that because android reads it as full because it hasn't been calibrated )
also, without a calibration, you might notice your battery gauge draining oddly...for example, you might see it quickly drop from 100 to 89, then drop steadily to 72, and then hang for a while at 71 (these are all just made up numbers)
so it means alot! but everybody has different methods and i've never seen anything officially released by spring or samsung to confirm methods...
I will say this though...I've read plenty about how since these Li-ion batteries don't have memory, the DRAINING method, while maybe correctly calibrating your battery, actually HURT the long-term life of your battery.
so heres what ive always done:
(the parentheses are the state of the phone)
(phone on) charge battery till LED blue
(phone on) unplug, wait till LED off
[POWER OFF]
(phone off) plug in, wait till LED blue
(phone off) Unplug, wait till LED off
[POWER ON]
When completely booted, power off again
(phone off) plug in wait till LED blue,
boot into recovery, wipe battery stats
unplug, reboot phone and use
it's always worked so try it out
Actually I'm pretty sure it doesn't fully charge to prevent over charge.. and the whole deal with you guys chargings 2-3 times after the light turns blue is just killing the life of your battery.

My question why is this in devolpment?
Fyi: both methos work but the complete drain does kill battery life. The pluging in multiable times dont. Android nows wheb to stop charging the battery to prevent over charge.

If it can stop at 92 percent to prevent overcharging, then it can do the same thing when it reaches 100 percent, no matter how many times you plug it in.
I don't know of many, if any li ion battery packs made today that don't have circuitry in them that prevents overcharging.
I put it in development because when you load roms, generally battery is a big concern. I cant tell you how many times ive searched for the same topic all over, I just figured it would be as helpful to others as it would have been to me had it been here and been a stickie at the top.
I've always thought battery calibration was more of a placebo effect, but I have no data either way. On a related note, here's an interesting article about battery stats and charging that was posted a week or so ago:
Android Police: Your Battery Gauge is Lying to You...
Having a battery keep at a full 100% for a long time is not good for li-on batteries. The 10% between 90 and 100% is basically used as a safety buffer. That's why the charge drops between 100 and 90 is much faster than the drops from 80 to 0. even though there ways to increase the actual capacity of the battery by using the methods above, you will still see a quicker drop from full to 90 almost instantly after unplugging the charger. I am in no way saying that those methods don't work in helping the phone read the actual charge of the battery, but they do help increase capacity a little bit. by rearranging the electrons in the battery. There actually is an article on google and on xda that backs it up. I'll try finding it

Lol.. wow alright.
Yes COMPLETELY draining a battery is really bad for a battery; infact if you do so you may end up with a 'bricked' battery.
But the phone also knows not to 'over drain' so with the method of clearing batt stats there's no harm done..actually. allowing your phone to die before charging is healthier than plugging it in before it dies.
I won't argue on the other note anymore; well simply because I don't know enough to continue just know I won't be taking that path
Sent from my SPH-D700 using XDA App
Thanks for the response. But also if you have a separate charger because you have multiple batteries, do you need to have to go through any of this? Or will the charger charge them to their true full state?
It will charge them to 100%. You'll notice it holds 100% for a lot longer.
Sent from my SPH-P100 using Tapatalk
The only thing that needs to be done to calibrate the battery is either flash at full charge or charge to full then delete batterystats, all this drain to dead and charge this way and that is pointless, though u will all argue otherwise, pointlessy

Yes thank you very much! I'm gonna give this a shot probably tonight after the Christmas Eve service and see what happens.
You should definitely add that NONE of this matters if your first usages out of the battery aren't proper. When you get the phone, you need to kill the battery before charging.. charge for 10-12 hours w/the phone off or in a dock, kill battery.. repeat 2 more times to condition the battery physically.
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.
Sent from my ADR6400L using XDA Premium App
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.
Sent from my ADR6400L using XDA App
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.

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!
The last couple of days I've noticed something strange with my battery. I keep it on the charger all night and when I get up in the morning my phone says the battery is at 100% and the charge LED is green. The instant I pull my phone off the charger it drops a couple percent. I thought that was strange so this morning instead of pulling the phone off I just shut it down. Once the phone was completely off the LED went from Green to Orange as if it was charging again. It look another 20 minutes to turn green again. I powered the phone up and as soon as sense is loaded I am back to 93% battery.
Anyone else see this? I've wiped battery stats and did the whole calibration but that didn't seem to fix the issue.
That is normal... Once the batt hits 100%, the charger goes off and lets it drop to 95% or so and starts charging again. It does this to protect the battery. Also when you turn off, it will restart the charge.
The battery is lying, but that's not such a bad thing.

My battery has been acting up the last few days as well. As in, going from a full charge to ~35% in 3 hours and then down to ~12% an hour later. No new apps added, nothing out of the ordinary done. Regular uses and charging cycle. I normally reset my battery stats when I flash a new incarnation of a new ROM, but after a couple of days everything seems to be back to normal.
I've been baffled by this, but have yet to find the culprit. An app or searching for signal are my only thoughts.

Hi,
That would suggest that your battery is flat.
Why don't you plug the charger in for half an hour ,then try booting again.
Yeah like above said your battery is dead, as soon as the light stays solid it means you can start your phone. Depending on how badly its drained itll take like 15 mins while being plugged into AC. This usually happens to me while playing a game and i dont notice the low battery lol
exactly the same thing happened to me just now...
Strange thing thou was that the phone was connected to the charger all night long and I just removed it from the charger
Charging right now... lets wait a bit
-update
Charger seems to have died in action.....
what was your outcome adiallo77 ?
-update 2
Charger started to work fine again ...
I'm confused now
I had the same problems when I first install cwrecovery, after a night in the charger it was working fine again
I just started having this problem with my phone. The battery is not charging at all, my phone won't turn on, but the red light is blinking. I have been reading and trying all day everything I could find in xda, but still no results. I can't remember which ROM I installed last, but it has stock kernel, ICS probably virtuous.
This usually happens when your battery has drained completely.
Here's what you need to do. Put your phone on an hour long charge before trying anything.
Don't put the phone for charge on the PC or in the car, but use the standard wall charger that was provided with the phone. Whatever happens, don't pull the phone off charging.
After an hour of charging is completed, switch on your phone as you normally would, without unplugging the charger. Your phone should be fine.
Let it charge to 100%, calibrate your battery and perform a restart to maintain the right graduation for battery levels.

Have you tried a different battery?
Have you checked if the battery fits tightly?

i don't have an extra battery but the one i have does fit. I'm gonna see if i can find me another battery borrowed.
Does the orange light continue to blink after a few minutes? I had this problem a while ago but the light would blink for about a minute and then stop, then the battery wouldn't charge and my phone wouldn't turn on.
What I ended up doing was putting my battery into my Desire HD and charging it for 15 min (aligning the pins and just holding the battery down since its too big to fit in the HD and letting it charge) and then I put it back into my sensation and it would pick up charge.
I would suggest getting an external charger and letting the charger bring your battery up to 5-10 percent then putting it back into the sensation and try to charge it/see if your phone will turn on.
The same thing has just happend to my gf's sensation XE, she left it on all night charging, now it wont turn on, tried everything. Its all stock since day one. might have to send it back, her last HTC phone broke too (wildfire), Any tricks to try and get it to turn on?
The lights come on at the bottom keys, but no display ?
My battery has started acting strangely for quite a while now. Essentially what happens is that when I try to charge it, it usually jumps straight from around 50% to 100%. Then, when I unplug it, it will act as if it is discharging normally for around 5%, then it'll jump down to around 45% and discharge normally. And it doesn't happen consistently, once in a while it will charge properly. It happens whether I am using a wall, car, or USB charger. I believe it started when I installed a nightly of CM 7.2 a while back, but it's still happening to me in SBF'd 608, and it could have started when I was still on CM 7.1. I downloaded a battery calibration app, and tried that several times, but it didn't help. Does anyone have any advice?

battery is bad, or phone isn't charging correctly

That will fix the symptoms, but I was hoping to figure out how to actually fix it. The battery charges perfectly fine in another D2G, and it charged fine in mine on 608 last night, so it's not the battery. It looks to me like a software issue. I'm going to see if it keeps doing alright on stock, and if it does, I guess I can assume it's a Cyanogen issue. Or an issue with my install of Cyanogen, anyways.
Use another d2g to charge the battery to 100%, then put the battery into your d2g, start up the phone, plug in the charger for about 15 minutes,delete /data/battd and /data/system/batterystats.bin, power off the phone without unplug the charge, after the phone finished power off, unplug the charger.start up the phone and use it normally to it automatically power off,fully charge the battery without start up

I've been having issues too with my droid 2's battery lately, not the same exact issue you are having, but it's like when I plug it to the wall to charge, sometimes (randomly and not often) it won't recognize my battery and won't start charging and a '?' icon will appear on the battery (if the phone is turned off). I've been reading about this and people say that if you 'calibrate' your battery, the problem will be gone, so check in the Google Store for a battery calibration app and follow the steps. Good luck on it !
