I'm actually at the same stage as you. Full power off-charge, and a couple re-plugs to ensure I was fully bumped to 100%. Deleted the battery file. I'm currently in the discharge phase. I'm trying to speed up the discharge by running wifi tether and as many streaming apps as I can. Got er down to 65% right now. Trying to get this battery drained within the next couple of hours. Will report back soon.
[Droid Incredible Q&A, Help & Troubleshooting] CaptainTaco:
I gave up, and just started running an infinite stress test, that'll take your battery down pretty quick.
[Droid Incredible Q&A, Help & Troubleshooting] deficitism:
Infinite stress test? Explain...
[Droid Incredible Q&A, Help & Troubleshooting] CaptainTaco:
a cpu stress test with no end time.
[Droid Incredible Q&A, Help & Troubleshooting] alexdw369:
Not if you're using Advanced Task Killer to kill itself. And you can verify that it's not running using OS Monitor or SystemPanel.
[Droid Incredible Q&A, Help & Troubleshooting] CaptainTaco:
Well, finished killing, and recharging the phone, and I'm surprised to say that it worked perfectly...

unplugged my phone immediately after the light turned green (with the phone on), that was about 15 minutes ago, charge still reads 100%, similar to if I had done the charging trick with the phone off. Just a recap, previously (before doing the steps provided in this thread) my phone would immediately (within 10 minutes) drop from 100% charge to 89-92% charge after unplugging, similar to many others.

So this is a pretty big find for incredible owners, I believe this issue is what plagued our battery life. Considering it is now about 20 minutes since unplugged, still reading 100%. I have to say, I'm impressed. I didn't think this method would work at all, let alone that well...

However, if you don't do the trick to fully charge when completing this method (After the phone reads charged when on, shut the phone off and let it charge till the light turns green... again...) I don't believe it will work as well if at all.

Whelp, congrats OP, You just made it so I don't have to buy a larger battery.

EDIT: At the conclusion of writing this post, the battery just finally dropped to 99%... still a whole lot better than dropping immediately to 89%.
[Droid Incredible Q&A, Help & Troubleshooting] LeoD:
I agree totally! The suggestion to fully charge the phone doing the unplug then plug it back in till fully charged was a good observation. :) as soon as I read it I realized that actually sounded like it should be the correct way to go. One thing I did notice was after I fully charged, drained ( now remember your supposed to drain the battery till it dies so again your charging to full without the phone being on) was when I took it off and started using my phone which of course was at 100% was in a little bit about the time captaintaco mentions here it went to 99%, 98% already a difference than before. I'm using a 1800 mah battery and because I'm off today my usage was lite. I'm over 24 hours up time and 6:30 min awake time. I still have 38%charge left on the battery. I did use the wifi and made a few calls, visited the market etc. I'm very impressed already ( even with the plug/unplug trick I never got life like this ) but yes I still need to see if the battery reacts the same after I change it tonight. Thanks op and captaintaco ( I believe it was you who suggested fully charging plug/unplug) for this info.;)

BTW: I just received a 2150mah battery from verizon today which I do not think I'm going to be needing :)
[Droid Incredible Q&A, Help & Troubleshooting] jasonb1985:
Ok. I killed it and charged it back up. It definitely did not fix the issue where the battery drops instantly. It was down to 94% after about 5 minutes. So for me it seems to have done nothing. I really wasn't expecting it to actually work, so I'm not too upset. So I guess ill continue to rotate through my batteries using my external charger to charge them.
[Droid Incredible Q&A, Help & Troubleshooting] jermaine151:
I followed these instructions, except when the phone went dead I charged it completely while powered off. I figured that I wanted the OS to record full as what it charges to while the phone is off. So far, so good. Typed this message and still at 100%. I've attached an image of how much use I got out of the stock battery during discharge. I'll post another after this discharge.

EDIT: It dropped to 98% 20 mins after posting this. :)
[Droid Incredible Q&A, Help & Troubleshooting] deficitism:
No dice for me. Deleted the file, powered down and charged fully, killed the battery, recharged, unplugged, let it sit idle for a few with the screen off, woke it up, 94%! I'm even using the seido. I'm really hoping the next ota (or rooted ota rather) fixes this bug.
[Droid Incredible Q&A, Help & Troubleshooting] wraithdu:
I gave this a shot also. Charged fully, then turned phone off and charged till green. Booted into recovery and renamed the file. I dont really like deleting system files ;)

I was pretty proud of myself, I managed to kill the battery in just under 4 hours. Screen on at 100% + Pandora + Maps with GPS will really do a number on ya.

Then recharged to green with phone off. I tured it back on overnight, woke up today and it's still at 100%. We'll see how it goes from here...
[Droid Incredible Q&A, Help & Troubleshooting] taypotts:
Here is proof that this works! I was about to get 18 hours of heavy use from the phone! I was trying to kill the battery so I could charge it normally!

[Droid Incredible Q&A, Help & Troubleshooting] jermaine151:
You weren't supposed to delete the file until you were charged fully.
[Droid Incredible Q&A, Help & Troubleshooting] jermaine151:
I haven't used the phone a bunch today but its still at 76% 10 hours later!
[Droid Incredible Q&A, Help & Troubleshooting] Bxsteez:
I've just done a full charge and did this calibration. I'm going to loop on a video with all radios on and see how long it lasts.
[Droid Incredible Q&A, Help & Troubleshooting] jasonb1985:
do you know how long it lasted under the same conditions before deleting the batterystats file?
[Droid Incredible Q&A, Help & Troubleshooting] punchcard:
Has anyone seen the documentation on the batterystats.bin file? I'd like to stop some of the guess work and nail this down.
[Droid Incredible Q&A, Help & Troubleshooting] JTCGiants56:
Right now I am waiting for the battery to die so I can recharge. Before I deleted the file, I let it fully charge with the phone on, but forgot to let it fully charge with the phone off as well.. Not sure if this is going so effect this at all. Can anyone confirm that it does/doesn't.

Also, anyone have any idea how often we are going to have to re-do this recalibration process so that the battery can consistantly stay alive for this long?
[Droid Incredible Q&A, Help & Troubleshooting] Bxsteez:
No never really watched videos but i would get like 8-10hrs with normal use. I should note that i'm using the TP2 (1500mAh) battery and i fully charged with the device off.
[Droid Incredible Q&A, Help & Troubleshooting] disciplined:
This did not work. Here is how I know:

I did as the OP said and then let the battery die from full to forced shutdown. I plugged it in for several hours with the phone off. While it was still charging (orange light) I turned the phone on and it switched to green. No amount of replugging in the charger would set it back to orange. The battery stats said full. When I unplugged it, it dropped back down to 95% within 5 minutes.

Basically I would need to do the whole shutting it down and topping it off thing again. Hence I don't think it worked.

Could be wrong.
[Droid Incredible Q&A, Help & Troubleshooting] taypotts:
shouldn't you of waited till the orange light turned to green b4 turning it on for the first time? that's what I did and it's still holding true..
[Droid Incredible Q&A, Help & Troubleshooting] Bxsteez:
My phone just turned off. It was awake and streaming music while looping on a video for 7hrs. Now I will recharge with the phone on and see if the calibration worked.
[Droid Incredible Q&A, Help & Troubleshooting] disciplined:
Well I thought the idea was to get it so that the battery charges to full even with the phone on. If I still have to turn the phone off to completely fill the battery then what's the point of recalibrating?

Am I off?
[Droid Incredible Q&A, Help & Troubleshooting] sucker4pa1n:
I think by turning it on before its green basically caused the OS to look, see that batterystats.bin was missing, and create a new one starting at when you turned it on, thus it's calculating percentage with 100% not being accurate.

Of course, I agree with someone else who had posted asking what exactly that bin file does... until we know what it is and how it works, there's only trial and error to see if this makes a difference.

Edit - did some looking around, I guess that file is something that is inherited from Linux? It makes me wonder, if we took a multi meter to the battery, couldn't we just edit the file to make it truly accurate? I'm guessing all it would store is voltage and maybe amperage...
[Droid Incredible Q&A, Help & Troubleshooting] KidJoe:
I was thinking of trying this, but a question came up in my mind...

I have the stock 1300mah, and the Seidio 1750... So which battery should I use when I do this process?

And what will happen when I switch to the other battery? i.e. is the calibration going to be off since the other battery is different capacity?
[Droid Incredible Q&A, Help & Troubleshooting] jermaine151:
I didn't look at the file but the extension makes me think that it's a binary file which may be tricky to edit. The recalibration seems to have worked for me. I'm getting quite a few more hours out of my phone.
[Droid Incredible Q&A, Help & Troubleshooting] JTCGiants56:
After using the phone for 20 minutes it finally went down to 99 percent. I really can't believe this trick worked so well.
[Droid Incredible Q&A, Help & Troubleshooting] th3drow:
The first time I took it off the charger this morning I got good results, battery seemed to drop normal instead of the immediate initial drop. Will see if it holds up.
[Droid Incredible Q&A, Help & Troubleshooting] colonel187:
Does the phone need to be rooted to do this. i can't mount -a cmd says no such command? sorry for such a noob question.
[Droid Incredible Q&A, Help & Troubleshooting] Big20x:
ok I am having an issue can anyone help?

I have the Clockworkmod Recovery v2.0.1.3 installed f.y.i.

I type adb shell in the cmd prompt and receive

~#

then type

mount -a

I get this returned

mount -a

mount: mounting /dev/block/mmcblk1 on /sdcard failed: invalid argument

mount: mounting /dev/block/mmcblk1p2 on /sd-ext failed: no such device

although I do have root and have installed the clockwork mod I am relatively new to android and any help would be appreciated.
[Droid Incredible Q&A, Help & Troubleshooting] sucker4pa1n:
Yep, I ran into that one. Didn't look into a hex editor or anything on the market; plus, I can't remember now but I couldn't really do too much with it as I have yet to root my phone. Besides, even if I did have a hex editor, it'd be difficult to figure out what exactly to change.

I wish we knew what made the file, and if there was a way to disambiguate it.

*shrugs*

Someone else had asked about using the stock 1300 or their 1750 Seidio battery for it - I would think it'd be better safe than sorry, pick whatever battery you'd use normally, and do the procedure with that battery. It probably would read slightly different on different batteries, due to differences within each individual battery. Definitely between HTC and Seidio manufacturing, I would think.
[Droid Incredible Q&A, Help & Troubleshooting] sucker4pa1n:
I'm rather sketchy on my *nix as I haven't messed with it in about ... eh, 6 years. But from what you wrote there, it *sounds* like it isn't finding your sdcard. If someone has more knowledge on the subject please let me know.

Basically, mount is the same as "mapping a drive" in Windows.

This kind of came up from the man page listed from a google search for "mount man page".

I was going to link it, totally forgot I've been a lurker and haven't posted enough to be verified. oops.
[Droid Incredible Q&A, Help & Troubleshooting] viccyran:
you're fine, just run the command to remove the batterystats file. you're not mounting the sd card or the "sd-ext", just the memory on the phone
[Droid Incredible Q&A, Help & Troubleshooting] chadstone30:
this is definitely a legitimate software problem.

i never considered my incredible's battery life to be poor. since it's impossible to get two full days of use out of any smartphone ever you have to charge them nightly anyway. as long as you can get a full day out of it that's all you need. unless of course you're having a contest to see who can have the most battery left over when they go to bed at night. still, out of curiosity, i decided to give this a shot.

i first completely discharged the phone to the point where it shut itself down. i then fully charged the phone while it was powered off. then i booted into recovery, deleted the stats file, rebooted into sense and again ran the battery down to empty with my normal usage. no crazy video streaming and cpu stress tests. i got well over a day and a half out of it, quite a bit longer than i had ever gotten previously.

after that i charged the phone while powered up. when the green light came on i powered it down and plugged it in again. the light turned orange and the phone continued to charge while powered down for another 15 minutes.

moral of the story is to charge this phone while powered down if you're going for marathon battery life. deleting that stats file does nothing from a "recalibration" standpoint.

Yep, this is exactly what I have found. It's a definite problem with the Incredible. The EVO does not do the same thing. :eek:
[Droid Incredible Q&A, Help & Troubleshooting] x1208x:
This method did not work for me. I even bumped charged it 4 times prior to clearing the battery stats :/

The sad thing is, my friend's battery lasts almost 3 days with regular use. And I double checked all of his settings and he has all sync's running, background data, window/screen animations on, etc. I noticed we had different stock battery serial numbers so I tried his battery in mine and my phone still drained like crazy.

The only different thing he was doing that I wasn't, was he was letting the battery die to about 5% then he would charge it powered off. I've tried this a few days in a row with zero success.

can't wait for cyanogen to release froyo for incredible! especially since HTC might not have it complete till the end of the year with sense :/
[Droid Incredible Q&A, Help & Troubleshooting] Lcsglvr:
hahah...that made me laugh. I never thought of running that to drain battery quickly. Good tip!

Do that, stream, wireless tether ,and some other things and your battery is gone after 10 minutes.
[Droid Incredible Q&A, Help & Troubleshooting] Cronus1995:
I wonder how fast we can actually kill the battery on these things? haha
[Droid Incredible Q&A, Help & Troubleshooting] MachString:
Just charged while off and then bump charged a few times, it defently made a diff on the batt percent drop. I reset the batt stat with the recovery menu. My batt was at 4.138 when fully charged, I'll post what it is after my batt dies and I recharge with the phone on only.
[Droid Incredible Q&A, Help & Troubleshooting] MachString:
After completing the recalibration by charging fully when off (with a few bump charges i got to a voltage of 4.138) then deleting the batt stats file from the recovery and discharged till auto shut down. I then charged the phone while it was on until i got the green light, unplugged it and my batt was at 100% with a voltage of 4.169...It then took 50min and 48sec to drop to 99% with a voltage of 4.133 (only using the phone to check the percentage about every 10min). This was a great improvement from it dropping to 95% in like 5-10min before i had recalibrated.... I am currently at 95% and 4.11v after 2hours and 30sec. (as before light use, mostly standby).... Thanks |OP| and all who contributed, this definitely worked for me. (FYI i have a stock battery).
[Droid Incredible Q&A, Help & Troubleshooting] chadstone30:
now i'm running the nightlies of the cyanogenmod 6. this battery charging thing still happens. when the phone indicates it's full i can power it off and plug it back in and it charges for a while longer. if it's a software thing it's deep in the code. and very annoying.
[Droid Incredible Q&A, Help & Troubleshooting] x1208x:
Didn't want to hear that :/ I still can't figure out why my friend can get such long battery life out of his phone without doing anything special.
[Droid Incredible Q&A, Help & Troubleshooting] jmdearras:
Definately a problem

I use the Incredible a lot, and had horrible battery life. I bought the Verizon 2150ma battery, and got a little better battery life, but 12 hours was about all it would do.

Then I found this thread and tried the shutdown reconnect method to "top off" the charge. This took well over an hour. But my battery lasted over 24 hours.

Something is wrong with the charging process, absolutely no doubt. :confused:
[Droid Incredible Q&A, Help & Troubleshooting] bigsushi:
I'm in the process of trying this to see if it helps my battery life. I charged my phone to the point it said the battery was full and then turned it off and plugged it back in to 'top off' the battery. It's been charging while off for five hours now and the charge light is still orange.

Anyone have any thoughts as to why this is happening or what it could mean?

Trouble

Im guessing i have a new model when i went to reboot mode went to delete battery stats and have done so, then immediately rebooted the system. Drained the battery completely and let it turn off. Finally left it off while charging the battery to full capacity and once the light turned green i turned it off and stopped charging. This trick did not work for me, did i do anything wrong, can someone please help, thanks!

PS on my battery 411 it says the android system uses 43% display 13% bluetooth 9% cell standby 9% wifi 9% ezcam (app) 25% realtime traffic (app) 25% and internet 2%....could this be why my battery life sucks or are you guys running a lot and still maintaining good battery life?
[Droid Incredible Q&A, Help & Troubleshooting] Archangel:
So if i am correct, instead of going into ADB to type in any commands (which has been virtually impossible for me to do) i can just reboot into CW recovery after a full charge and delete the battery stat under advanced then let it run down til it shuts off then charge like i normally would?

Also do i have to charge while it is on then shut it off and charge somemore all the time? Thank you!

this crap doesnt work...I have tried multiple times with my 1750mah batt. I can still turn off my phone and get more charge time.
[Droid Incredible Q&A, Help & Troubleshooting] Θmega:
I don't believe that's the point of recalibrating your battery at all. Turning it off will always result in it charging longer until HTC comes out with a fix.

The point of recalibrating is for batteries that drain quicker than they should be because the phone isn't charging the battery completely, even when turned off and the light is green.

ok im pretty phone savey when it comes to technoligy and computers. but i have a question that i need a little more help in the calibration.

ok so i have the dinc rooted with the 2.2 foyo leak from 7/27 with a 1750mhz battery. i bump charged the phone to full capacity. turned it on and booted to CW recovery, went to advanced and deleted the battery.bin. rebooted phone to the main android screen and unplugged the phone and let it drain until it shut off. then fully charged while the phone was off. now is this the proper way to do the recalibration? i installed the correct drivers so i can load adbshell, but for some reason i cant load that in cmd. so i did it through clockwork. is this a suitable method? i want to make sure because after i charged my phone after the calibration i didnt notice a change at all. it still goes to 95% about 15 min after i unplug my phone. please let me know if i did anything wrong.
[Droid Incredible Q&A, Help & Troubleshooting] loccoelf:
Yes you did everything perfectly, as I said b4 this "method" or whatever you wanna call it is very misleading. The part that does work is turning your phone off and charging it. That will give you a lot more power. The problem is you have to keep doing that. So buy a lamp timer and set it to bump charge 3-4 times a night.
