How-to Train your Dragon[Battery]

To help with Battery Life you can do these steps exactly:
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, I tested this on my pops evo and my epic...MAJOR DIFFERENCE
After installing a new Kernel it is recommended tat you recalibrate our battery to get the most life out of your battery. I suggest using Phoenix kernel but your a grown man[or woman] choose your kernel
Hope this helps
Thx to bigdbag for these additional steps

My god. I was highly skeptical of this but I tried a quick version of the instructions.
I did the following:
1. Charge to 100% while phone = ON
2. Once at 100%, unplug charger and turn phone OFF
3. Plug in charger for 5 minutes while phone = OFF
4. Unplug charger and turn phone ON
5. Leave phone ON for 5 minutes
6. Plug in charger for 5 minutes while phone = OFF
and the results... are miraculous. I'm running Phoenix Kernel v.1.43 and stock rom w/ drm removed.

Trick trick trick trickle charge Battery is in fast charge mode when it begins charging from a certain percentage (although slow). When the charge is in the 90's and you unplug and plug it back in it trickle charges to completion. This does indeed work. Works best in my opinion when you do this after you let the battery completely drain, plug in, recovery mode, wipe battery stats and then turn on.
And then do what you stated above.

Yes!!!!!!!!
Totally gonna do this since my battery seems to be on the down side compared to everyone else's. :]

i also reccomend an external battery charger that u place the battery into. no need for the trick. Ive used this trick before i got the external charger and yes it does work very well!

+1 on the ext charger. I have two batt. If I charge with the phone... one- goes from 100 to 97 withing sec from when I unplug it and two- it doesn't last as long. Using the charge and switching out the batts. Stays at 100 for a while and it will last forever too.

I noticed this as well, so when my indicator LED turns blue and it says 100%, I unplug, then immediately plug back in until blue.. lather rinse repeat.. after about 3 or 4 times it finally stays at 100% when unplugged..
That being said, I'm gonna have to try to find an external charger and another battery...

My local sprint store sells a charger with extra battery for $49.99. Its an external charger that fits in your pocket. With charging cord of course.

tried this, doesnt' seem to work for me. I unplugged, turned phone off, and charged, but phone said fully charged after like 15 minutes, I assume once it says 100% on the green battery that shows up when phone is off that I shouldn't just let it sit there? its not charging at that point anymore is it?
then i unplugged, turned on phone, waited 2 minutes, turned off, charged again, 15 minutes or so it was fully charged again.

This reminds me of the chargobics that some ppl did on their evo to get better battery life....never really helped me.

So what you're suggesting (re: recovery/battery stats) is the following:
1. use the phone until the battery completely dies.
2. plug the phone in
3. boot into recovery (clockwork ?)
4. wipe battery stats
5. turn the phone on
6. do the 'plug me in' dance after it's fully charged
What if the battery is fully charged and you wipe the battery stats ?

idk i think i used to do something similar on my Hero and even back on my (WinMo) Mogul and Touch Pro and never really got much out of it......
However, today I did this and I swear I'm getting great battery life today. Have never gotten past 12 hours and I'm currently sitting at about 40% left at 12 hours. Could be the placebo effect but we'll see..... even played some angry birds today.

FTW!!!
Took 11 days to get here, but worth EVERY penny. I never need to worry about to battery life anymore. Hell, now that I charge my batteries using the external charger, I get atleast 8-10 hours with constant use, and my battery doesn't drop from 100 right away. I never get to the 3rd battery by the end of the day and thats with a 18 hour day unplugged. Worth it.

I have noticed some weirdness with the battery. I looked at the juiceplotter graph after the battery had been left charging all night, and it would charge to 100 and then over th course of half an hour drop down to 95% or so and then recharge up to 100 over and over and over again. I have taken it off the charger sometimes and the battery has gone from 100% to 96 % within a couple minutes and other times it stays at 100% for over an hour. It was a matter of luck as to when I pulled my phone off I guess, when it was really at 100% or really at 95-97% or anywhere inbetween.
Gonna try this PITA method of charging. Hope it works, but damn is it inconvenient.

The external battery charger is the way to go. i have also noticed when i rarely charge from the phone that it sometimes wont stay at 100 but for a minute then drop to 97. i get 55 hours to one battery with moderate usage.

This didnt really do anything. Unplugged from my charger at 1:50pm, its been exactly 2 hours and its at 77%. Mostly my phone was in my pocket, and I did very light browsing over 3g (maybe 10 minutes).
I'm on Latest Epic Experience with Mixup Kernel. And I don't have OC widget or Setcpu.

Try running the same setup with phoenix 1.43 kernel. Still super snappy and way better battery then mix up.
I'm also using external charger, 30+hrs with screen on for 6hrs

Is it really that much better? If so, what causes it to be better on battery life? I am getting great battery life using the mixup kernel because I have juicedefender and setcpu working hard to conserve battery life. Would Phoenix make a difference?

Just a FYI, Lithium-Ion batteries don't hold a memory like NiCad batteries did. It is also NOT good to drain them all the way down.

read and follow directions

[HOW-TO] - Battery Calibration

There has been much confusion and frustration surrounding our battery life and these custom roms. Some of us have great battery while others are having horrid problems.
I am writing this guide in the hopes it will help all of you with problems getting that great battery life.
This is a guide written from my own experience and technical understanding.
First, Your phone should drain, on average, 1% per hour or less while in standby mode (screen off). If you are not getting this average, you need to calibrate your battery.
ALWAYS flash a new rom with your phone at 100% battery - no exceptions!
i know some guides say to run battery down to 2% and then charge, but i never had much luck with this.
1) Before you flash your rom, charge your battery to 100% with the phone ON.
2) Once it says fully charged, turn the phone off and plug it in and wait for the on screen display to say 100% (this will take 5 to 10 min)
3) Turn the phone back on, and plug it in and charge till it says 100%
4) turn off the phone and charge again while off until the on screen battery indicator says 100% (again this will take 5 to 10 min)
5) repeat steps 1 thru 4 as many times as you feel comfortable, I recommend at least twice (I do it 3 times)
6) when you are satisfied with the charge, and the phone is still OFF with the indicator saying 100%, unplug the phone, remove the battery, and place the phone in download mode (hold vol down and plug into the PC)
7) flash your package (this is done in odin with the battery removed)
8) The first boot after the flash needs to be into Clockwork Recovery, wipe battery stats at this time (most roms will boot into recovery automatically, if not, boot into recovery manually)
9) after you have wiped your battery stats, wipe cache and other data (if the rom you are flashing requires this, if not, skip this step)
10) Boot the rom to the homescreen.
11) from this point on, you will use your phone like normal until the phone completely shuts off. this SHOULD take a while. you should see improved battery life during this stage. If not, dont panic, just run the battery down until the phone shuts off
12) once the phone shuts off (try to time this to happen at bedtime) plug the phone in and allow it to charge in the OFF position
13) once it is at 100% again, use the phone like normal and enjoy your new battery life.
IF YOU ARE DOING THIS WHILE NOT FLASHING A NEW ROM
Do steps 1-4 as many times as needed, I recommend at least twice, i do this 3 times
on the last charge up (your phone should be off while charging during this step) unplug the phone and boot directly into recovery and wipe battery stats. then proceed with the rest of the guide.
TO TEST THIS
charge to phone to 100%, try not to mess with it for an hour or so.. (light usage at most) you should still be at 100% or 99% after an hour. If you are at 95% or below, then the calibration has failed. (unless you have been using the phone or are in a very low to no signal area).
this calibration method is crucial to good battery life. Before I started doing this i was getting very bad battery life. Click on my username and look at my previous posts.. you will read about me *****ing badly about my battery, this is what I did and it has worked amazingly well.
I hope this helps
I combined a lot of techniques ive seen in other threads and some websites and then created this technique which seems to work really well.

I have used this technique and can confirm, it works well if done properly.

Are the first few steps what is referred to as "bump charging"?
I think this has worked quite well. I flashed Humble 1.2 (at 40% battery) last night, charged up, then started this procedure. After I got done, I took it off the charger and after 15 minutes of trying a new game, listening to a minute of music, and checking various things, I was still at 100%. i left it off, went to bed with wi-fi on, and woke up at 95%. Awesome. My all-day phone is back.

What happens after the calibration process? do i have to do this everytime i charge my battery or does like normal mean i can just leave it charge whenever. Also with what frequency should i be doing this? once a month calibration?

Just did this... 1 hour 15 mins. and still at 100% Sent two text messages out and played Words with Friends for a minute. Thanks!

Did this and it didn't work advice on what I am doing wrong I did the bump charge 2 times ran the phone down 100% and am now looking at 88 percent of next to no use after about an hour and a half of having the phone on.

I am in the same boat with you.....I'll just have to accept the fact that I will have to charge every 6 hours, which was a 2 hour step up from the TB.

This works, going on 17 hours and still at 65%.

What I am curious to know is what is usage like for the people that this worked for. Don't get me wrong I'm not doubting the op but I am a pretty heavy user and even so I'm not really experiencing this awesome battery life everyone talks about when I'm not using it heavily

For all of you that are getting the great life, what percentage does it list for display? This is under settings > about phone > battery use.

I'll have to try this method. My battery life is actually worse now after I tried doing the drain to 2% method. I'll report back with my observations.

Are we talking 3G or 4G here?
I would find it useful when people are talking about how good (or bad) their battery life is to know if they are in a 4G area and have 4G turned on, or are they using 3G only?
Trying to figure out how bad a hit 4G takes on my phone...
Thanks.

So I tried this out yesterday...I don't have a rooted phone so I could not wipe battery stats (does anyone know how to do this without rooting your phone?)...but I did follow steps 1-4 three times and I have gone 23 hours on my charge without having to plug it in. I am in a 4g area and had 4g and background services on for the full 23 hours. Had bluetooth, GPS, and wifi turned off. I sent a couple texts, used whatsapp to send texts, used google voice to send texts, made 3 phone calls (about 4 to 5 min each) played angry birds for about 20 min, played words with friends for 10 min, surfed the web on and off, was on tapatalk and browsing forums for about 20 min and I installed a new keyboard and web browser on my phone in those 23 hours.

I am very curious to know if this will improve battery life after that first initial bump charge.
If you do a regular charge after depleting the charge, do you still see improved battery life?

Yes. The phone will pull the necessary power for download mode and the Odin flash from the USB port. Just be sure to use a primary USB port (usually the ones on the back of the computer), rather than a hub, as the hub tends to cause problems.

Is there any way to calibrate the battery again?

After buying the phone (factory charged) my girlfriend and I plugged the Chacha into the computer for a while to transfer songs and some files. Then we ran the battery down to empty by playing some angry birds and left it to charge until green (around 6-7 hours i think)
Should we not have plugged it in at all and let it run down? I didnt think it would be a problem since my Optimus One can calibrate the battery any time but I just read that not all Chachas are rootable. Havent found out if hers is rootable though...
Is there a way to recalibrate the battery as of right now?

Wait, what?
What do you mean by recalibrate the battery? For how long do you have the phone?

We bought it yesterday but thinking back to what the guy said before we left, i think we screwed up somewhere by charging it for 20 mins (while transferring data) then letting it run out of power, then charging for 6 hours until the light went green.
Should we have let it run out of power then charged for 6 hours straight until the light went green? And to top it all off, the phone has the dumb Dialer bug Hope FastReboot helps with that since no root access means no apps that can restart the phone with the one touch.

Well first of all calibration, if the guy had any idea what he was talking about means to discharge your phone 'till it's off then charge it for min 8hrs. But this process hasn't been used since smartphones came into the scene.
The calibration now is performed after a few charge/discharge cycles. Also if you plan to charge your phone, use the provided power plug charger and not from the PC/laptop USB.

So it's an app that does the same thing as CWM. Since it works on rooted phones only, CWM is already installed and wipe battery stats is a CWM option. So this renders this app useless

Oh alright. So i'll just tell her to wait it out with full discharge -> full charge cycles? How many cycles would that usually take? Right now she says its on low batt after just 8 hours or so. Stupid Dialer bug...

It's not just the dialer issue. There are a lot of useless apps that run in the background. It depends what your gf is using the phone for. Get S-OFF and latest SW versions.
3-5 cyles.

Alright thank you ^_^ I'll get her to implement the fixes for the Dialer Bug and see what happens. And i'll ask my friend's brother if he has an xtc clip in his shop.

3full charge & discharge will be enough. as for the dailer issue is not much of draining the battery. battery drain occur most is auto sync with mails or fb & some those apps will frequently need to update itself. 3G/BT wont drain much battery you can last a good day or 2day without charging.

not much you can do about dialer bug - save battery by
- turn off facebook chat on fb website and phone
- turn off sync for stock news weather
- turn off some call settings (quiet ring on pickup, pocket mode, flip for speaker) which solves dialer issue (but not for me!)

When you delete this file, the batterypercentage will be resetted.
Then you must fully discharge the battery and charge it overnight.

Battery doesnt (very slowly) discharge

I already got this problem and been able to fix it with battery calibration (root) apps. But since about 1 week I cant fix it and I dont know if someone have the same issue.
When I charge the phone to 100% and unplug the power, it doesnt discharge until 3h after unplug. And between 45% and 30% the phone shut off. When I try to power ON, it say battery too low keep charging before power ON (something like that). When the battery is charge enough, its already at 30% and reach 100% very fast (maybe 15-20mins)
I did try to do battery calibration, reboot the phone and use it normally... but no success.. I already did this 5 times
I cant let it discharge to 0% because it automatically shutoff at 30-40%.
I use the "stock rooted YNG1TAS2I3 ROM. Includes root(enable in Developer options) and the rest is untouched, so it's OTA update safe" from Calkulin (thanx to him he does great work)
I didnt want to factory reset because like I said before, its not the 1st time I got this problem but its the 1st time I am not able to fix it !
And please, do not answer to buy the OnePlus 2
Thank you in advance, sorry for my english

Backup ur data first then flash coloros then let it discharge completely then charge it to 100% without powering it then Power it on and check with ur battery. If it repeats then it's sure you have to replace the battery
