Calibrate Battery thread - This is how you do it!

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.

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
Sent from my Epic 4g

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.

[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.
From my Charge - XDA Premium

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
Sent from my SCH-I510 using XDA App

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.

[Q] Battery Inconsistencies?

Hey guys, is anyone else here experiencing the battery level going up when you restart the phone?
If my battery is at 70%, and I restart it, it'll be at 76% or even higher and remain that way for quite a while (remains a consistantly drain, not a single major drain in a short period of time)
This is something that's been happening since I was stock (Retail device from T-mobile store on launch date)
Here's some info:
-S-OFF using Revolutionary, and then later upgraded to 4.0.0.9 via terminal emulator
-Rooted stock (no rom uploaded)
-1900 mha Anker battery
-Battery stats wiped
-UncleSpoon's battery icon mod
even after all that, it'll still do it. So is it just me, or is everyone else experiencing this?

Yes, you have to re-calibrate your battery stats.
No, the CWM menu option to wipe battery stats is not right, for some reason.
Go get this free app: Battery Calibration
Charge your battery all the way up and let it sit charging for a few minutes after you see the light turn green (while turned on and booted up)
After it's been green for a few minutes, open this app and click the big "calibrate" button, and then un-plug it from the charger.
Let it run down until it turns itself off, without plugging it in. This means no usb to the computer, either - and don't turn it off manually.
After it turns itself off from lack of juice, plug it in (wait about 30 seconds) and then turn it back on. If you turn it on too quickly weird things may happen, depends on how depleted the battery is. (usually there is 1 or 2 % left so it's ok)
Leave it plugged in and turned on until fully charged. After that, you can feel free to play with it, but you should run it up and down a few more times without charging in-between. The first one is critical to do this way, though, or you are just wasting your time.
You MUST be rooted, or it will not work. (said for others who may need this info)
Tip to drain battery - screen brightness all the way up, screen to not turn off, and turn the flashlight app on. Leave it sit for a few hours.
Tip to charge quickly while on: Turn all wireless and data communication off, tap power button to turn screen off (keeping phone on)
Good luck, it'll solve the problem though.

I used battery calibration to wipe my battery stats (I did it in recovery on my 3G Slide, so I'm aware of that alternative method)..
I've let my stock battery get to 0% but that was pre-root.
After reading all the charging problems with the CWM, I was a bit afraid to attempt the 0% drain on the new Anker.
Are you running 4.0.0.9, and does it charge fine? I'd hate to deplete an Anker since I have no external battery charger.

Removing the stats only doesn't calibrate the battery, check the calibration guide in my sig, for a correct method that works for any android device.

Seriously, that's a good read.

I agree.
What I recommended was better then just wiping battery stats with CWM, but nowhere near as good as what Ace42 linked us up to.
I'd recommend reading those threads and doing that instead, I am more then happy to be corrected and shown a better way.
(FYI - I depleted a stock battery completely, both in CWM 4.0.0.8 and 4.0.0.9 to test the charging issue. You will always be able to charge it in the phone, even if you bring it completely to dead.
The idea that you can't is a myth, and was a concern until it was proven not to be true.)

Can't calibrate new battery

Hello.
Recently (~one+ month ago), I replaced the battery of my OnePlus.
The problem is that I can not find any way to calibrate it. I have tried the "manual method" (fully drain then charge, then fully drain again and charge again e.t.c.) many times. I even tried to use some applications (that I really do not trust them for their reliability, but...).
Today, I have found some time and reinstalled the phone's OS (I am using Ressurection Remix - latest build). Nothing changed.
Here's the problem, with some concepts as examples:
I charge the battery until it gets to 100%. I use the phone for example till it gets to 60% (the drain is NOT quick. It needs some time till I get to that point). Then, if I restart the phone two (2) times, I get again 95-99% of battery. Then again, I use the phone till it gets to, for example, 40%. I twice reboot it again. ~90±%! If I do not reboot it twice, the battery indicator will not change. Or it will just lose 1% percent (for example, if I reboot one time when the phone is at 60%, I may get 59% when the phone will power up).
I charge the phone until it gets to 100%. I let the phone drain out the whole battery (0%). I boot it up again. No, the battery is still alive and it may give me around 70-90% (I am not so sure about those numbers, but the idea is that the phone can still operate - there is enough juice for the phone to work).
Any ideas? I really do not know what else to try.
Thanks in advance.

Battery indication problem

Hello, i have a problem with my phone. Recently i changed my battery to a new one, probably not original, even though it has oneplus branding on it. And ever since battery indication on the phone making no sense, once it's fully charged, phone shows that percentage falls to 0 very quickly (100 to 1 in ~3-4 hours screen off time), but once it hits 1%, it stays like that for at least 6-7 hours with battery saver turned off and quite heavy usage of phone, like i imagine it should with a new battery. Also, once it hits that 1%, AIDA64 shows about 2500-2700mah under "charge counter" section. Is this a software issue or its related to the battery itself? I tried to completely drain it until phone shut off and charged fully after that, and still the same problem.

So noone helps me, thanks

Here you go
For non rooted phones the battery calibration is done via cycle livesnof the battert:
1. Let your phone die
2. Charge it while powered down to 100%
3. Turn it on charge to 100%
4. Let it in charge for 20min even when 100%
5. Turn phone off charge to 100%
6. Go to recovery and clear cache
7. Charge the phone in power off to 100%
8. Turn it in repeat steps from 3. To 7.
Do this in 3life cycles, so once u do step 7. Twice use your phone normal, and repeat 3 times.
If it didn't help there is a recovery tool. It will wipe your phone and install new original OOS with new batterystats file.
