To the point that your phone shuts off? Is it bad for the battery?
I know overcharging it isn't because it drops a few percent and constantly charges back up to 100%...
Just wondering, thanks.
From what I understand,our li.ion. batts do not let you discharge all the way.( to save the life of the battery)

What ^^^ said. Even when "drained" your battery will still put out 3.5 volts +/-.
Ah, gotcha. Wonder why AT&T says to power the battery to 100% and drain until notified of a low percentage... Hmn...

That is basically calibrating your battery that you see so much about. The phone is designed to turn off when the battery voltage drops to a set level as it requires a minimum voltage to function. On the 100% charged side, sometimes the phone may think that the battery is fully charged when in reality it has not reached 4.2v.

If I am trying to make sure my battery stats have the full minimum and maximum capacity I run down to 1% before plugging in.
If I think my battery stats are fine I don't worry about when to plug in.

Basically, any device that uses a lithium battery has a device or process that monitors voltage and sets a minimum voltage that, when reached, turns off the device. This is required, otherwise lithium batteries would have a battery life that was only good for a few cycles. This applies to every application where lithium batteries are used. Phones, laptops, ipods, basically any modern portable device... or in my case, radio controlled model airplanes. The airplanes I fly use electric motors, and the voltage shut-off has two stages: one that cuts power to the motor but leaves power to the control surfaces so you can still land without crashing, and one that shuts off all power -you crash if you drain it this far. I know it isn't phone related, but it might help you understand the way it works. It's just the way it is. I've destroyed batteries in one cycle by running them below minimum voltage.
Thanks for all the info, ladies.

Hi guys,
I have an incredible S rooted and running on Android Revolution HD 2.20 . Had that ROM for a month without any problems until today I charge my phone while using my YooBao (11200mAh) external charger , and it told me that my phone consumes more power than the charge, please close all unused applications.
I was like totally lost. I had that charger for almost half a year and it worked perfectly on my device without any problems.
Now the problem that I'm experiencing is that my phone discharges faster than it charges. and that totally sucks. I need some advice,
Could it be my battery faulty or was it the charging port?
My thoughts are your "YooBao" has ruined either your battery or the phone itself.
Hopefully it's just the battery..
That's usually why phone manufacturers ask you to use their products in comparison to other "suppliers"
Update:
I flashed Nik's v4.5 over my ARHD and I tested it by leaving it to charge until 63%.
Feeling glad that at least it's charging up to 63% , I concluded that my port isn't damaged although I wasn't able to charge using my external charger. Pretty pissed.
I went up to my phone and used it while it was charging . To my horror , the 63% dropped to 61% while I was using and STILL CHARGING . WTF?
Now i'm gonna wipe all my apps and do a clean flash and no titanium backups for me .
God.. help
Did you have gps WiFi or large processes running in the background? It could easily do it.

Well , initially I thought it was , until I wiped my phone and didn't restore my apps and I'm sure it wasnt the processes that are causing this **** . Charge my phone overnight and my phone stops charging , woke up to find that my phone is only at 50% charge and the percentage drops super quickly.
Can anyone tell me whether the charging port or the battery is covered under warranty if it's within my warranty period?
Any advice whether I should get an Ankers' battery or should I purchase another original battery that cost me SGD$68?
Couple of things you could have a look at. Check in your battery menu that your phone is on AC charge mode. Also install current widget to see how many mA your phone is drawing while in use and to check the difference when its on charge. The original charger supplies around 900mA to the phone @ around 10%.
Calibrate it?

After a day of test.
Finally I got tired of it and I did a simple test to really test whether my battery is draining too much or not.
I plugged in my phone yesterday night to charge at the AC adapter, surprisingly it was charged to 100% straight with no problems.
I was tired alrd and I used an iPhone 3G as a spare phone. Throughout the day I carried 2 phones out and I noticed something:
At the end of the day, my InCs still had 78%. (WiFi 3G off) .
It means that the draining of my battery is not as bad as it seems. The real problem is that I am unable to charge properly.
When im charging at 61% , I use the phone when it's charging, the percentage can drop to 58% (which is not possible as my GPS is not on) .
So advice people:
Should I?
1) Get a replacement battery,
2) Bring to the service centre (No warranty left and pay)
Do you think:
1) Port problem
2) battery problems.
Let me know

It's for me a usage problem, got the same message too. You're running too much apps at once and never use a taskkiller. You also had GPS WiFi and Mobile Network on and maybe at full brightness. Close apps, I think you need not GPS while charging and if you have a WiFi connection mobile network isnt to be on.

Whats your way of keeping your nexus 7 battery healthy? I wanna keep it as healthy as I can for as long as possible. Nothing irritates me more than having a battery lose its charge faster and faster every day. Just to be clear im not asking how to prolong battery usage between charges; I'm asking how to keep it from losing its charge quicker and quicker when the power usage is relatively the same. One thing I do know is once it the battery hits 100% to take it off the charger. One thing i have heard is try not to let the battery dip below 50% and rarely let it completely discharge but I have also heard to ALWAYS let it die out by completely discharging. Feel free to add to the myths, folklore but preferably facts on how to keep the battery healthy and holding its charge very well
N7 has Lithium polymer battery, right?
Well then read about it https://en.wikipedia.org/wiki/Lithium_polymer_battery
But from what I heard: rather charge it then let it drain below 30%, don't let it charge too long, and so on - probably the same stuff you heard or read yourself
but that's something that upsets me: no chance to replace the battery. Used my DHD for 2 years and after those 2 years the battery was just ****ty. Replaced it, works like a charme. On N7 or TF300T there's no chance to replace the battery. Right now I'm using TF300T very often when I'm not at home, so even with dock and tablet it'll most probably go below 20%...well if that's bad for my battery, then I don't know what to do if it doesn't last an entire day :-/ (though that'll take some time)
Certainly I wouldn't let the Nexus battery completely drain but maybe down to 5 % then fully charge

You can change the battery on the nexus 7. Its actually relatively easy and simple to do so. I havent had the need to replace it but I did have to disconnect it. Just pop off the back with your choice of apparatus. I used a small flat head that i could wedge between the sides but a guitar pick is another popular choice. Then just disconnect the wire and take the battery out! no screws just slight pressure holding it in. right here is a guide with pictures showing it step by step.
What I would do is time my charges. In my experience, my Nexus 7 gets fully charged in 2 and a half hours from 20% battery. I then take it out immediately so that in won't get hot(sometimes it does, and also to save energy.:good And also, if after 3 days my battery is still 50% or above, I drain it to 20% then charge since Li-ions tend to not want to get not drained often.xD
Charge early and often and keep out of extreme temperatures. It boils down to that.
If you can, charge it nightly. Try to avoid discharging below 20%.
And a little myth busting... There is no need for you to manage its charging cycle, it will do that itself. Charging a LiIon/LiPoly battery partially is NOT a "charge cycle".
If you're actively using your Nexus 7, just charge it as often as is reasonable, nightly should be just fine. If you're NOT using it for an extended period of time, discharge it to 50%, turn it completely off and store it in a cool (20c/70f range) location.

The battery's are $20 for a new one so as long as it lasts a year I don't mind buying another one. In another question has any one bought a replacement battery yet? And if so does the charge last about the same as stock?

Dirty AOKP 3.5 <&> m-kernel+ a35 (t11)
My advice : Charge it when it's between 20%-30%. That's the ideal charge point. Any lower and you're just damaging the battery and any higher is just a waste. As for immediately plugging it out once it hits 100% is utter bull. You see, these modern day batteries found in most phones/tabs have their own resistors which decide how much power enters the battery or if it should enter at all. Once a battery hit's 100%, the resistors kick in and block all incoming power. The "discharging" many believe to happen if we over charge beyond 100% doesn't exist. What happens if you leave a phone or tab alone idly ? It discharges like always. Same thing here, which is why you see your battery bouncing from 100% down to 97%. When that happens, the resistors will allow power back in and thus charging it back to 100%. So you can leave it charging all night and not having to worry about it going beyond 100%. It'll get it's own sh!t together .
So bottom line :
1. Charge when it hits 30%-20%.
2. Don't discharge it (0%) and back to 100%. It doesn't work on modern batts.
3. Don't worry about pulling out when it touches 100% immediately.
Enjoy your tab

Nope. Reboot away. Remember, the only harmful thing you can do and see immediate effects are charging the battery in a very hot enviroment or if you charge it when the battery is 40-50 degrees celcius. It'll either swell up or it'll just catch on fire or explode.
When I charge my phone it reaches 99% and it remains there it never reaches a 100% charge.
And my led notification is always red never goes green.
Did anybody else notice this?
Sent from my HTC One using xda app-developers app
Maybe you are using 3rd party application like Battery Motifier in which the settings of battery full is only set to 99%. I am using this application for charging my phone then this app notifies me once it was fully charge using a sound notification. Try to check your applications installed to your phone maube you have same kind of application or the likes... hopefully it helps

I had to get an exchange for my first handset. It had major gaps, and battery never fully charged.
It seems it was due to a dodgy battery. Even if the phone was left on charge for 10 hours it still wouldn't fully charge, turned on or off.
If it gets really hot while trying to charge after 98% it may be the same thing, and you should possibly ask for an exchange, or get it checked out.

How do you know the battery is at fault?
Sent from a pizza..
Why not let the phone discharge until it shuts off, then try to completely charge it from empty. I had an atrix once that would only charge to 99 after most Rom installs until I did this. Always figured it was a battery calibration thing.
Interesting fact, Lithium-ion polymer batteries do not charge to 100% capacity by design. They are actually quite difficult to charge correctly (in the electrical engineering sense, it's still plug and charge for the end user) and it is not worth the additional hassle to get to a "true" full charge. What the phone reports as 100% is only 2-3% off of the theoretical max capacity so in practice the difference is not noticeable.
It's hard to say if this effect is whats responsible for what you're seeing, but it could be related. Another possibility is that you simply haven't let it trickle charge long enough to report 100%. The last few % charge of any phone battery is going to go at a much slower rate compared to 20-90% for example. Really the only thing you can do is the somewhat standard advice to get a full discharge/charge cycle in to let android re-calibrate itself.
this is normal, it eventually does it,m dont worry about it
sometimes if i use the phone whilst its on charge it turns green
im not bothered, 99% is good enough for me it trickles down at the end really slowly
even 95% is good enough i usually unplug it at 95
I had the same thing when I got my phone, I was using a cheapo micro usb charger that did not have the beans to charge the one.. it got to 99% always.
Switched to proper one with phone and voila green light & 100%
For the record an iPad 3 (aka "new" iPad) charger works if you swap the USB cable also.
I am using the charger that came with the phone, and it has been an hour on 99%, any advice? To the ones who reached the 100% mark, how long did you leave it at 99%?
Happened to me too, with stock charger.
Finally got it to completely charge. I let it discharge to 2 percent than charged it with the touchpad charger. Most probably the first step isn't required. The charger outputs 2A. Will try other chargers including pc usb..

i had that problem on my s2 with some custom roms. it would charge to 100% if i unplugged it rebooted and plugged it back in. also it went away after 1 or 2 battery cycles
Reboot device when at 98/99%, then it will show 100% for some reason.

There's no official fast charge ROM support available for Galaxy Note.
You can increase the charge speed my optimizing your battery performance. Most Samsung phones take 3-4 hrs for charging depending on the phone state.
Make sure you clear all apps before keeping your phone for charging as any running app can eat up the battery. Look up for any suspicious apps which may be eating up battery.
Use CPU spy to make sure that your phone is going imto deep sleep while charging, if not there's a malicious app which is keeping up the phone awake or there's problem with the ROM you're using.
Also check that your phone is not getting heat up while charging, as it could mean a great power loss which could highly affect the charge time.
If nothing works try changing ROM.
Or at the last case if you are a regular ROM chamger then try to clear up battery stats through some app available from play store which requires root.
One more issue which I once encountered was with my charger cable being faulty( although no signs of physical damage) and I changed it with a locally bought cheap cable and miraculously my phone stopped heating and charged faster.
The more you care for your device, the better it gets.
Hope I have helped you.

I checked my 2 Notes, max current it draws is limited by the charging circuit. Seems no kernel can change that value in the Note.
It charges max at 1 Amp, no matter if you attach it to a charger that can deliver like maybe 1000 Amps, the max current is 1 Amp.
That 1 Amp is also until it reaches about 90% ... since Li-Ion is very picky and actually dangerous when overcharging they slow it down.
It's a statement that I hear often in the wrong context : I bought a new battery and it takes very long to charge. Actually that is a sign that the battery has a big capacity. You can only take what you give.
Of course the charger and cable are very important. I would advice everyone to buy one of those usb charger doctors. http://forum.xda-developers.com/showthread.php?t=2451375
