Do not bump at step 12

I <3 Humble 142!
[Verizon Droid Charge] jjenkins2005:
This post has been very useful... I went from having about 5-6 hours of battery life to lasting 15Hrs with 10% remaining... This is with having push email receiving about 750 emails a day, about 1 hour of calls, some medium text usage and other basic usage.... This process help keep me from going insane and tossing my phone from my next Delta flight

[Verizon Droid Charge] chiahead52:
750 emails a day? WTF seriously? thats like one every 2 seconds...that would drive me insane..who gives a crap about battery life at that point...geez...why in the world would you want you phone basically exploding every other minute getting the email notifications?

glad the calibration helped though
[Verizon Droid Charge] blarrick:
You know how clearing your battery stats give you great battery life for the first full charge? Well... after this calibration that's what it's ALWAYS LIKE! OMFG!!!$(!$!$(!$!! I mean, I've done like 3 different types of calibrations before this one and they only really gave me better battery life for the first charge but this one is sticking. It's great! GUTTA CLICK THANKS....!
[Verizon Droid Charge] Piercing Heavens:
Theoretically this method will take about a week to complete?
[Verizon Droid Charge] blarrick:
I completed it in about 4 days. I wasn't trying really, the battery would be pretty much dead when I was about ready to go to sleep so I'd just run the Flashlight app + Music + browser to sap the battery from 10% to 1% in like 4 minutes flat lol.

It's quite easy to do, just don't think about it. Do the charging part and wipe battery stats then afterwards just charge whenever it's at 0-1% about 4-5 times.
[Verizon Droid Charge] criticalhit:
I am really glad this is helping MOST of y'all. Yeah about 4-5 days to complete this process .. depending on your usage of course. And don't forget this was done and writen for the Charge but im seeing that it is working for almost any rooted phone. :)

[Verizon Droid Charge] lolminraise:
Do you know if wiping and reflashing a rom (but not wiping battery stats), will reset this?

What about just flashing a rom without wiping?
[Verizon Droid Charge] snwbrd:
Is it possible to just flash/copy an accurate, properly configured battery stats file for a particular phone in order to avoid going through the charge/discharge cycles?

Sorry if this was asked before.
[Verizon Droid Charge] criticalhit:
Im not sure.. but every battery is different so I doubt it.

I <3 Humblecomb!
[Verizon Droid Charge] criticalhit:
I never wipe anything when flashing new versions of the same rom... I never see a difference in battery life when I flash... I have flashed 2 updates to humble since I have calibrated and am still having awesome battery.

I <3 Humblecomb!
[Verizon Droid Charge] lolminraise:
Do you happen to know where the battery stats are stored? Could I access it with root explorer?
[Verizon Droid Charge] Scrappy1:
Strange thing about the Charge is that there's no way to stop the abnormally high idle drain. With Fascinate, you could play games by disabling data network, or go to airplane mode, and get absolutely flat battery response, maybe drain 1% every 4 hours in idle.

With stock Charge, even in airplane mode, with all radios off, the thing still drains 4% an hour. Checking processor usage history with system pannel shows nothing abnormally high. There has to be some hardware or radio thats always sucking juice, even in airplane mode. I blame LTE, since Fascinate on the same ver or Android didnt have the issue.

Lets hope for a miracle in Gingerbread.
[Verizon Droid Charge] MillionManMosh:
I've noticed that idle battery usage while connected to Wi-Fi is less than it is with data off altogether. That said, either way I can still leave it on all night and only drop maybe 5% from what it was when I went to sleep. YMMV.
[Verizon Droid Charge] Scrappy1:
What's your wifi sleep policy set to?
[Verizon Droid Charge] aaronDroid80:
I know what you mean. Here are some things that I've noticed during the past week. I'm running rooted stock EE4 with PBJ Voodoo, lagfix enabled. #1: LTE is a major battery hog and make the phone run really hot. Dead battery in about 5 to 6 hours with light usage. I live on the fringe of an LTE area, so I just disable it and run in CDMA mode. #2: I have not found a mobile data manager (i.e. Green Power or Juice Defender) that works on this phone, so leaving data turned on still puts a pretty heavy drain on the battery. #3: I've noticed that the Charge also doesn't sleep when it's charging, running at 100MHz the whole time.

I've started turning off data all together during the day, unplugging my phone at about 6:00 AM, and only turning on data a few times during the day, and using wifi at home. Here are some screen shots of what I had at the end of the day. There were times during the day where I was in a basement with little to no signal, so there was some extra battery usage there, but still good results. The following day, I had better signal, battery was still at 100% after 3 hours idle, and still had 27% battery left at 11:30 PM. Another thing I've noticed is that the battery is a glacier in this state, sitting comfortably around 77 degrees F.

Thanks to critcalhit for the [HOW TO].
[Verizon Droid Charge] jjenkins2005:
I'm an Ops Manager and I get alerts regarding infrastructure devices, we monitor 29 global sites, and over 15000 nodes and 5000 different applications and services so you can imagine how this must be... I rely heavy on my device and didn't want to have to get the extended battery because it made the phone look and feel like a brick.
[Verizon Droid Charge] criticalhit:
:D

I <3 Humblecomb!
[Verizon Droid Charge] elucid:
With Humble and battery calibration, I lose 8-10% overnight (with 4G on, and autosync on). So at "idle" I'm losing 1% an hour. I have auto sync on for gmail, calender, and push on for exchange corp account. The phone easily gets me through my day.
[Verizon Droid Charge] AlexDeGruven:
Your usage patterns are way outside the standard design envelope (read about "building/desiging for the 80%"). There's no way you should expect to get through a day without either being plugged in most of the day or using an OMFGHuge extended battery.
[Verizon Droid Charge] blahdc:
Criticalhit, do you know what the difference is between using CWR to clear your battery stats and the "Battery Calibrator" packaged with the humble rom? Have you compared battery life using the 2 different methods?
[Verizon Droid Charge] aaronDroid80:
Here's another test scenario. Again with mobile data turned off for the majority of the day. This is where I was at before going into the basement with no signal:

And this is what 6 hours in a hole will do:

Basically what I'm saying is that if you are going to brag or complain about how good or bad your battery life is, substantiate it with some usage stats. clearly if you use the phone as just a phone, and signal is good, you might get 2 full days out of it. But if you are frequently refreshing data, then you might only get 6 hours. It's all in how you use your device.

To quote a fellow user: "good day."
[Verizon Droid Charge] criticalhit:
All the battery calibration app does is clear the bat stats via an app instead of the manual cwr method. So they should be essentially the same.

I
[Verizon Droid Charge] blahdc:
One other question, how do you know that the battery stats are wiped out if you let your phone shut off? On the battery calibration app it says to let your phone die.....

Just trying to figure out why there are different variations on calibrating the batteries.
[Verizon Droid Charge] criticalhit:
i don't let the phone die.. ever. if it shuts off i turn it right back on for charging. if you clear the stats then you start all over. im not sure i understand your question about the phone dying and knowing if your stats are cleared... your stats get cleared when you clear them, then your phone builds a new stat file based on charging/discharging. so far i have tried like 3 diff methods to 'calibrate' correctly. This thread is what worked the best for me thats why i wrote it :p
[Verizon Droid Charge] Ace42:
My phone turns off at 1% is that when I should plug it in?

Sent from miuiTouch 4G
[Verizon Droid Charge] blarrick:
That's when I did it, my phone would sometimes reach 0% but only for about 6 seconds and I couldn't reach the charger in time. I just did it at 1% and it worked fine, if it does shut off just plug your charger in and as soon as you can power the phone on and continue charging from there.
[Verizon Droid Charge] Ace42:
Thanks I think ill start the process over instead of starting from that step.

[Verizon Droid Charge] lolminraise:
Do you know if it is important to flash roms at 100% battery or not?

Can you also clarify in your instructions at what point exactly should you unplug your phone? Should you unplug, then start in CWR and wipe battery? Or unplug after wiping battery stats, then reboot? Or wait until wiping battery, rebooting, and letting it hit 100% again before unplugging?

BTW I am getting 30+ hours with light use now. Thanks!!!:D
[Verizon Droid Charge] criticalhit:
Doesn't matter what your battery is at for flashing roms. I have flashed at all sorts of %s. I have flashed like 4 uodates to humble since writing this thread and i have not recalibrated since writing thread. I unplug right before hitting the wipe bat stats option in cwr. Then reboot via cwr. I will edit initial post tomorrow... its bedtime :p

Do you have screen filter enabled? If so, at what setting? Also, at what % of brightness do you set your display brightness, with or without the screen filter app? TIA
[Verizon Droid Charge] zeuswsu:
Is there any need to recalibrate your battery if you flash a kernal over an existing kernal? Or is calibrating totally rom related?
[Verizon Droid Charge] Ace42:
Not needed for a kernel change up afaik.

Over the weekend, I stayed home and purposely tried not to use my phone. I had 4g on the entire time and was still getting push notifications from my email, but I checked email on my computer. I only had a one minute phone call and no text messages.

My results are below. :D

I used to drain 7-10% per hour idle before the calibration.

This is so awesome. Im glad that I could help... this is some seriously extreme battery life even if you were idle.

I <3 Humblecomb!
[Verizon Droid Charge] broomulack:
Display at 2% huh? You must truly have not looked at the phone at all. I think if there was ever anything that proved that the display is a resource hog, the biggest one of all, this has to be it!!
[Verizon Droid Charge] braveally:
So if my phone resets during this process...

So I have been attempting to calibrate my battery for a while now, and each time, my phone decides it would like to reset. This happened all four times I have tried the battery calibration app included with Humble. Although random resets is nothing my phone does on a regular basis, just when calibrating the battery ironically. So if my phone happens to reset while I am waiting on it to discharge, will it screw up the calibration process?
[Verizon Droid Charge] criticalhit:
Not at all my friend.

I <3 Humblecomb!
[Verizon Droid Charge] JOrtenzi:
No offense, but what good is 3 days if battery if you aren't going to use your phone for anything?
[Verizon Droid Charge] criticalhit:
Lol. I think he is just saying that the calibration helped overall...

I
[Verizon Droid Charge] :
Cool
[Verizon Droid Charge] lolminraise:
This was just to show that one can idle for less than 1.4% per hour with 4g on. I still charge my phone every day, but now if I unplug my phone at 7am and I don't have to worry about conserving battery even if I can't get home until 11pm.

I think this battery calibration method works so well, people aren't even coming back to this thread because they don't have any problems. The other calibration thread advertised by the FAQ sticky is still being bumped because their calibrations aren't sticking after the initial bump charge.
[Verizon Droid Charge] braveally:
Wow!

G-Willikers! Batman!

I got my full charge last night using the posted method and left unplugged since last night. Right now I'm at 15% after light/medium use all day. Did some spotify (online with 4g) on my bike rides to and from work, several emails and calls, some rss, etc. I am just now hitting 15%.

Seems like my battery was only ever about 60% charged after the results. Less than 5% an hour. Can't wait to complete this process!
[Verizon Droid Charge] braveally:
Did I screw up?

So my phone hit 0%. Just as I was putting in the charger, it shut down. I pulled it out due to a bit of panic. It would not turn back n so I had to replug it to turn back on. It is currently on the charger. Did I screw up? Wipe stats again?

Sorry if I sound hyper anxious about this. It keeps making me think of my drafting class where one mm off and the whole schematic is off.
[Verizon Droid Charge] criticalhit:
No you are fine just continue with calibration

[Verizon Droid Charge] lolminraise:
I just want to add if you unroot your phone and root it again, you need to recalibrate again.

I can tell because my phone would sit at 100% charge for 3 hours. Then start draining all fast.
[Verizon Droid Charge] coryj558:
I've read this thread, but may have missed this question: Are you saying that at your step 12 to go back and do steps 1-6? Or, are you saying to simply plug in once and let charge to 100% as reported when the phone is on? (You said you did one of these sequences 4 times)

Thanks!
[Verizon Droid Charge] d-loko:
What he means is he repeated steps 10 & 11 (Full charge, full drain) 4 x's.

The 1-6 bump charging is done prior to resetting batt stats.

Although its great to have a fully charged battery all the time, this KILLS the life of the battery very quickly.
[Verizon Droid Charge] joshakajosh:
Maybe I'm wrong but cant you just turn off 4g completely if you live where there is no 4g by going to settings, mobile network settings, and change the system selection to CDMA only?
[Verizon Droid Charge] jmorton10:
Yes you can

~John
[Verizon Droid Charge] sbradley07:
I started this process today. I read that the whole process takes 4-5 days, which I assume relates to the 4x charge/discharge cycles.

Does the rate of discharge matter? I was hoping to "force" it to get it done quicker. On the first discharge, I ran full screen brightness, turned on bluetooth & gps, ran the nav, played some tunes, played some netflix, etc to get it to drain fast...which it did.

Is this wrong? Should I just be letting it discharge under normal usage?
[Verizon Droid Charge] jmorton10:
Discharge it any way you want.

~John
[Verizon Droid Charge] sjanderson:
Just looking for more clarification on multiple batteries - I have the original battery as well as an extended battery. After reading everything here, it sounds like the battery stats are linked to the actual battery in use. In that the extended battery and the stock battery have different capacities, how would the new battery stat file apply to both?

Or should I just pick a battery and stick with one? thanks.
[Verizon Droid Charge] scuba_bald:
31hrs!

I think I finally did the calibration correctly. After bumping the battery 20 or so times, I continue on with the wipe of battery stats and I'm proud to say that my phone finally hit 0 at 31hr and about 10 min.

My area doesn't have 4G yet, so my mileage may vary Monday when I head to the city.

3G, Wifi, about 4 hours of playing tunes on my sdcard, about 1 or so of web browsing throughout the day

push of Gmail

every 20min sync with lotus notes server for corporate email

sync of Facebook every hour.

I'm almost done with my first recharge and will continue with the full discharge portion next.

Thanks again for the instructions!
[Verizon Droid Charge] vi3tboiii54:
Hmm i havent tried bump charging yet and im only getting less than 8 hours with moderate use. I am in a strong 4G area, GPS off, bluetooth off, auto rorate off, auto brightness on, using juice defender, yahoo mail sync off, facebook sync every 4 hours. When i first calibrated my battery i waited till it hit 4200mv then i wiped the stats, then 3-4 cycles afterwards, perhaps i have a bad battery.
[Verizon Droid Charge] njones15:
Bump Charging FTW

I am on Humble 5.0 RC2 with Fugu Tweaks and I am already at almost 18 hours up, and still at 46%. That's with wifi on and 4G the whole time, no gps though. I did exactly as OP said when calibrating, and it worked like a charm.

Do you repeat same steps for 2 batteries?

I got 2 batteries prior to this information about calibrating the battery. I did this bc I noticed as soon as I got phone that the battery life is HORRIBLE.... so I got 2 batteries. Started process yesterday with roots and all....now I'm hooked.... lol, so again, my question is Would I Need To Repeat Same Steps for Both Batteries? Thanks in advance.
[Verizon Droid Charge] buhohitr:
YES, It is recommended that any NEW battery, you should calibrate before using it. This is important for any new battery.
[Verizon Droid Charge] PhenomHTPC:
I am attempting to perform this calibration on my Charge running Tweak's 1.4 with PBnJ kernal, and I am experiencing something that I don't think is supposed to happen. After completing the first step (charge to 100%) and then turning my phone off to let it charge to 100% again, my phone does not vibrate but instead reboots every time. Any Suggestions? Or is there a setting I am missing?

Thanks in advance!
[Verizon Droid Charge] JihadSquad:
It's a glitch in the PBJ kernel. It reboots whenever the phone is off and plugged in.

Also, I don't really see a point in doing this. Li ion batteries don't have any sort of memory, and Google has said that clearing battery stats does absolutely nothing with the charge reported. The % you see is directly translated from the voltage read from the battery.
[Verizon Droid Charge] PhenomHTPC:
Thanks for the help, I will more then likely have to bring my battery in to Verizon or look into purchasing a new one.
[Verizon Droid Charge] bigjonmoo73:
Awesome write up! I am definitely going to give this a try with my 3500mAh battery because it does not last as long as it should!
[Verizon Droid Charge] Vorzal:
Thanks for the post! Performed this two days ago and while yesterday's performance was less than stellar, I understand that it takes awhile for the phone to relearn how to optimize battery conservation. Today's performance was the best ever. I only plug it in while running Escort Live in my car (which drains the battery almost as fast as my car can charge it, to be fair), and at 11pm it's still at over 50%, with all the usual facebook and internet browsing that I am normally up to.

I noticed also that my charge would reboot upon reaching 100% during the bump-charge procedure, which as it sounds is likely due to my usage of the PBJ kernel. A minor inconvenience.. didn't stop me from completing the procedure ;)

Thanks again!

I'll never understand how people get this much battery life. I bought two new batteries off ebay, on tweaked, fp5, no sync, no gps, lowest display, eliminated all bad apps via bbs. Also disabled most things with autoruns. I might get 8-10 hours if barely on my phone like responding to the occasional text. I've spent hours and hours on this battery stuff since getting this phone early November.

I just feel like there is something major I am completely missing here. I do get a lot of texts, do those cause wakelocks leading to more battery drain? I barely talk on it if ever.
