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

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.
I have had the tablet and the dock battery's drain all the way while connected and with the tablet turned off. I do have the latest firmware for the tablet and the dock.
Has anyone else had this issue?
The battery dock still has draining issues, even while off. I'm not sure why your tablet drained as well -- perhaps the dock started to charge it and tablet turned on due to it? or maybe the tablet started to charge the dock while it was draining and ended up both being dead.
yeah Im really not sure what happened but I do know when I went to turn on the tablet it started up and only had about 13% battery left when it was fully charged when I turned it off.
Check your wireless disconnect policies, if its set to Never then that might explain why.

Im not sure where to check that.
OFF as in you held the power button until it asked if you wanted to shut off, or SLEEP, as in just tapped the power button (or lock button on the keyboard)?
The Lock key on the keyboard, or just tapping the power button puts the unit in SLEEP, which is not really sleeping, it just turns off the screen and depending on your wireless power policy, WiFi may still be on. Apps still run. Stuff still communicates with the interwebs.
off as in i held the power button and hit shut down.
Mine is doing it as well. Did a complete shutdown yesterday after fully charging both the pad and dock. Just turned it on and the dock is blinking orange. I also had the WiFi disabled. Even when you do a shutdown it seems something is not shutting down.

ASUS never said that they fix the dock battery drain issue while tablet is docked and powered off. Have they?

im not sure. At least i know its not just me.
I hope they push the update where we can see the battery live for the dock soon.
Mine is doing the same thing. Keyboard was charged when I closed the lid and then blinking 6 to 8 hrs later. Wasn't doing this with firmware .12 with the keyboard battery indicator. I really hope they bring back some of the .12 features soon.

My keyboard dock no longer seems to hold much if any charge, I left it charging yesterday until the keyboard dock light stopped flashing and stays on steady (I assume that means its full) and now 4 hours later the keyboard dock light is flashing and no longer charging the tablet.
if i recall, this is a known issue with the dock. When not in use, it will still drain the battery. If plugged into the tablet at the time, im pretty sure the tablet will drain also. I think asus is aware and i thought i saw somewhere that there will be a fix once 3.1 is out, that will put the dock into a very low power state when not in use.
so i guess we will see once 3.1 is out

Same issue. Had a fully charged dock and a partially charged Transformer.
Was very pleased to see the tablet start to charge when I docked it, and not so pleased when I got up in the morning and both were dead.

I had my phone for 3 months. It did this issue before and I removed the battery, it started. Now, it doesn't start with or without the battery. I plug it and press the power for 10 seconds, nothing happens.
I had the phone running for like 3 days till the battery completely drained.
I plugged the phone and I feel it's warm on the camera area and still doesn't start after charging for a while. Total black screen!
I am on CM7 and CWM recovery installed. Any ideas?

Since the battery drained completely it may take an hour or better on charge to get enough juice to restart.
The phone can't start without the battery? with just the charger power?

Ya it just needs to get some serious juice on it before it starts weird issue but mine does the same thing. Plug it in to charge with battery and leave it for about 10+ minutes and it should start up with the plug in.

It's been plugged in for a long time.. Nothing yet...
and when it's charging, it usually displays a battery charge animation...
but the screen is totally black
I've never attempted to turn it on without the battery, but with mine, when the battery has completely died, I can plug it in and turn it on within 15-30 seconds and use it (as long as it's still plugged in). USB charge, I have to wait a little longer, though.
The battery was ok I had no problems with it and I checked the battery status yesterday it was "4 from 100 points" and "Good" health.
The phone did that with me before but it started charging when I detached the battery and inserted it again. I think it was some sort of hanging up and the battery had to be detached even if the phone was off!
It workedddd! finally!
As I said... I had to detach the battery and the power completely and reinsert the battery... This is really weird :S
Maybe it was flooded.

Sounds like a bad battery. Taking li-ion down to fully discharged damages them. The batteries have protection circuitry but if you take it down to nothing and don't charge it right away you could have done permanent damage. If a li-ion is damaged in this way it will never take a charge again. Get a new battery and see if that fixes your problems.
Not sure if this is related to 4.4 or the nexus 5 specifically (pretty sure its the hardware). While using the phone during charging it doesn't charge fast enough to keep powered on. My wife was on facebook when hers went down, and I was playing knights of pen and paper when mine went down. The phone will eventually just power off and flash the red led 8 times. The only way to power it back on is to load the bootloader first (vol up + vol down + power) then press the power on start. I tested this on 2 black 32GB Nexus 5s with android 4.4.
This is really easy to test, next time your device is low keep using it after plugging it in. It will eventually just "go dark" and you'll be greeted by the flashing red led.
Here is a link to the google group product forum thread I created, please post feedback. This needs to get fixed, hopefully just an update can resolve it.

Yikes. This isn't good. The only time the phone may not be able to keep up with charge is when using GPS. If this is a widespread issue I'm sure it will be fixed. Unless you have a bad battery or charger! I will test..
Update:
Just played game Aurolux whilst charging for 10 minutes and phone gained 5%.

I tested it on both mine and my wifes phones, different chargers as well. Also the load on the devices was low, both were on wifi, she was using the facebook app, I was playing knights of pen and paper, both on auto brightness (in our living room, lights off). Same thing happened on both, screen just cuts out, red light starts flashing.
Hopefully it gets fixed, if more people will test it and post feedback here or at googles forum it would be great.

Same here. Zero issues playing games and phone charges.
Are you using a custom ROM or kernel? That could explain it. Otherwise you either have two did chargers, or 2 did batteries, or a combination of both.

I guess I could try to charge when it's below 10%, but maybe easier is if you try charging whilst using your phone above say 20%. If you still have the issue then I think it's device related, if not report back.

They seem to charge just fine when left alone. It just seems too coincidental that both phones would have the exact same power issue.

dont forget, the snapdragon has 'quick charge 2.0', you shouldn't be seeing that kind of charging issues. i mean, if it's something you're ok living with. but that sounds like a big indicator that the battery or charging module is faulty/will go bad soon

could it possibly be the cable, or the charger unit, or even the wall socket? these are all things that should be tested
I just wanted to say that I had the same issue as you and the problem so far seems to happen when you let the battery get pretty low before plugging it in.
The battery was down to about 8% when I plugged the phone in last night (to the lg charger). I actually left mine alone for about 30 minutes and when I came back, it was at 6%. I did verify that the display said "Charging" when the cable was plugged in. I unplugged the phone, and plugged it back in and started browsing the web on wifi and within another 15 minutes the battery had gone down to 2%. I turned off the screen and left it alone and when I checked it again, it was at 1%. At that point, I was worried about the phone, so I urned off the phone completely. When I turned it back on, it did look like it was charging again, but very slowly. At this point, I tried plugging it into another charger that I had, and it charged up fairly quickly.
Definitely pretty frustrating as I've never had something like this happen unless you have the usb cable plugged into a computer.
Last night I went to plug my phone into the lg charger...I could hear the charger buzzing slightly....I plugged in the phone and thought nothing of it really... Looked at my phone on the way to work and it wasn't charged past 28%.... plugged it into another charger at my desk and its at 47% in a matter of minutes...
I know op said he tried different chargers, but just tossing in my lousy 2c

The only chargers I tried were the ones that came with the phones. I got a bunch of others so Im going to give them a shot as well and see how this fairs.
Ok so Im sitting here trying to recreate the issue and it is different. I brought the battery down to 4% plugged it in and kept playing kop&p and the battery hasnt gone down, it actually went up to 7% but its holding there. I am letting it get to 10% now before I pick it up and try again. I swapped out between the n5 charger and my n4 charger both held it at 7% while playing.
Maybe this just has to do with battery conditioning, or maybe the snapdragon quickcharge ic.
Just checked the phone, from the time I started writing this till now (maybe 2 minutes) its up to 10% so back at it I go.
The charger that comes with the phone is horrible. Its the same type as the n4 which dies after 2 months. Don't use it, just use another one and you'll be just fine.

You know what really grinds my gears? The fact that I can't turn my Atrix 2 on until it has reached 5% battery charge (after having a full discharge). Has there been some solution for this? Even though I have CM11 on my phone, I am still using the original kernel that came with stock. Would a custom kernel have a fix for this? Thanks guys, later.
Anybody else?
i think this is kinda impractical.
Your charging a battery. Battery's need power and energy you cant expect a battery to power your phone up with nothing on it. Even when plugged in from the get go it has to run thru a complete circut thats powering everything as it goes, it takes more than you think.
Just my .02 cents.
It cant be obtained by the little charging port, say we had a laptop charging port that could hand the power. I would say yeah we could power up off a/c all day.

You can turn on the Atrix 2 before battery reached to 5%, yeah, you can
1. Just plug the charger in power outlet and in charging port of your Atrix 2 but do not turn on the electricity power switch, keep power supply off.
2. Now press and hold power button of your phone and immediately turn on the electricity power switch.
3. You should now see the boot screen and then you can leave the power button of your phone.
