This is the most common thing now. I have seen that the stock batteries are not lasting more than a year.
Just go ahead and buy a new battery. It surely is not the ROM
Is it gona blast or something? Lol coz I really need to use that phone untill new battery comes

Buy A new battery & everything will become normal
The same has happened with me. My Note is 13 Months old.
I was playing game AVP Evolution till late night. And in the morning battery died, I charged it to full 100% but as soon as i boot up with in 4 second the phone again switched off , No battery low warning nothing. It is really strange but the fact is that the Samsung battery are just die completely all of a sudden, unlike other phones battery which dies gradually as it looses power and all that ........
I ordered a new battery & everything is fine now.
My old battery is unable to boot my phone even for 5 sec.
I am running my note on the swollen battery for about 8 hours now xP.Sometimes it switch off as soon as I turn it on but rest of the time it runs just fine.Anyways I ordered a new battery.

likeliness of it "blasting"... not very likely.. possibility of it "blasting".. it is possible..
batteries just go bad... a battery is only solid for around 500 charges then they just start losing their charge faster. i mean we are using small computers so this is just going to happen more and more. different reasons could cause this.... use of phone (it is what its designed to do..lol), a "cell" could just go bad causing the swelling, the circuitry in the battery fails causing the swelling, your charger goes bad and takes the battery with it (i had a cat bite thru a cable and it ground out..next day the battery showed signs of swelling and within a week you couldnt snap the battery cover on)... etc....
use is up to the user and their needs... there is a danger of the battery shorting the phone out totally and it never working again too. its not something that happens often but it is a solid possibility, so basically use good judgement...
it's usually caused by over charged (u don't unplug the charger when it reach 100%).
I've been using my Note more than a year and my battery still flat as it is new.

i beg to differ... the batteries have smart circuitry to protect against this. overcharging has not been a problem for years... i personally have left one of my notes on charge for days... it always stays on charge for 5-6 hrs past it being 100% and it still is a strong battery.. also just because a battery is flat doesnt mean its good... the swelling just makes the fact it is going bad more obvious...
I agree with kawgirl

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?

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..

Let me know how it works ok... Seems like maybe its a stock charger issue...or maybe i just need to let it discharge to less than 2% most i ever let it down to was 9%...keep me updated please...
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.

i'm currently using my note 1 as a secondary monitor and it is plugged into the standard charger while doing so. Will the battery be constantly 'zapped' as I use it? or the battery can remain 'like new' if it's always plugged into AC?
Thanks!
Might be,might be not. I did that sometime, even on my laptops without any problems. But the recommended is unplug when it full charged and charg when its 1-10%. I use battery doctor app for trickle charge for long live battery. And btw the OEM stock bettery is cheap anyway. From now till ur battery is getting drain like hell its would be take like 6month to a year.
Just saying ...

It's better to discharge it completely, then recharge it completely from time to time.
Full cycles of charging and discharging keeps the battery healthy for a considerable time.

Also, keeping the phone on charging even after it hits 100% causes the battery to swell. You will not see the effects immediately, but after 4 months, the battery will be swollen on one side. And swollen batteries like to self destruct.
Every battery can be recharged several times[for exm: 500] If you charge it 5 times per day = 100 days battery life. So i think its better to dont remove adapter when battery hit 100%. The new cell phones and laptops got protection and they dont charge the battery when its fully recharged.
This is just my opinion.
Some time ago I did a little research, because I was using my phone as a wi-fi modem for my laptop. Most opinions said, that constant plugging may affect your battery life and best is not to keep it plugged when fully charge too often and for too long.

no it actually does not cause this... the batteries and phones have smart circuitry which prevents battery overcharging.
now fully cycling a battery 1-2 times a week will extend the life of the battery..
As far as I remember from the tech-news, newest energy cells (li-ion and li-poli) shouldn't be charged like the old ones - I mean charge 12h, then empty it completely and repeate the whole process 3 times. I read it on polish site some time ago and they we're also saying, that keeping phone under chargerer can harm battery or even mainboard.
But as we can all see, there are many different opinions about that

Mine did. Swelled a bit on the side, cover used to creak whenever I pressed on the other side
All (reputed) devices that use Li-Ion batteries use controllers that will automatically cutoff charging once the voltage reaches 4.200V/cell.
So you cannot over charge a battery by leaving it on for long duration.
Unlike the older Ni-Cad batteries, there is no memory effect. so there is no need to fully discharge it periodically
In fact, deep discharge of Li-Ion battery will irreversibly reduce battery capacity (Wikipedia -> Li-Ion battery -> Battery life )
So, I'm nervous about the fact that I can't replace the battery on my ONE. So far every night I've been staying up late until the phone dies, then plugging it in, waiting til the light stops flashing, then powering it up to charge while on overnight.
Problem is, this phone has awesome battery life. Right now at 10.30pm, I'm sitting at 41%, and debating just leaving it unplugged all night.
So what's the deal with memory on these batteries? How much, say over a 2 yr span, will charging a non-drained battery shorten its lifespan or lessen its capacity?

Lithium ion batteries are awesome. They are lighter, smaller and do not suffer from "memory effect."
Do not drain then fully recharge this phone on a regular basis. That will accelerate capacitance loss. Keep it charged as much as possible, avoid fast charging, try to use your PC to charge it overnight. Do not leave it charging for too long (i.e. days on end). Though on board computers can refuse charging, it is best to stay on the safe side.
2 years, you will definitely notice a decrease in battery life, but by the time it becomes intolerable, you will have upgraded. I can almost guarantee that.
EDIT: Please add to/refute any statements I made if you have greater knowledge on this subject, people.

As was previously noted, what you're doing is actually the worst possible thing you can do to a lithium ion battery. In general, best practice is to keep your battery somewhere between 10%-95% charge whenever possible. Once a month, you should "cycle" your battery under 10% (but not fully drained) to keep everything in peak condition. If you're ever not going to use the phone for any length of time, best practice is to drain to 40% and store in a cool, dark area.
When you first get a new device, you do want to condition it by doing three to five (varies on the device) full charge/discharge cycles, but after that, once a month with a conditioning cycle will take care of things for you. And again, as was previously noted, it's not a great idea to leave your phone charging overnight because you can't always depend on the battery controller chip.
These newer cells are all rated to relatively high cycle lifetimes, so I wouldn't worry overmuch. At that point, capacity is supposed to start degrading, although naturally it's going to happen a bit earlier for any number of reasons. I'd be much more worried about avoiding heat though than overcharge.
I'm assuming charging it slowly would keep it slightly cooler than a wall socket and closer to room temp, the better.
There is probably some other reason, but I'm not the person to ask. you can do some independent research. :good:
Just charge your phone when it needs it and don't when it doesn't. Do that and you'll be good until you upgrade no problem.
EDIT: Oh, beat me to it... haha
EDIT: Also, does the 40% apply to phones? Mobile devices never really turn off, they just go into deep sleep, I'm told. I was going to say that too, but then I remembered this. Does the 40% rule apply to non-removable batteries?

It's a question of how much voltage you're chucking into the battery. If you use a low-voltage wall adapter it'll be the same as if you were charging from your PC.
The 40% rule applies to any battery, and they'll all discharge over time anyway (connected or no). If you shut your phone off, everything powers down except (if memory serves) what's necessary to run the internal clock. The impact that has should be pretty minimal (unless you're trying to bury your One for a thousand years, in which case...can't help you there).

Who would buy a low voltage wall adapter?
And yes, I would like to bury my One safely for a thousand years, so when it is found by the generation of humadroids, they will see it and be amazed that a civilization so primitive could achieve such technological mastery.

I don't know that I bought any, but I have a few lying around from yesteryear's gadgetry.
And at that point, why not launch it into space instead, a la HTC Nexus One?
So I use my phone as my alarm clock and also run the Relax and Sleep app all night. Otherwise I'd just plug it into my lappy throughout the day and not worry about it.
But that raises another question: running the phone overnight while charging it at the same time. Bad juju?
I plugged into my lappy last night around midnight, woke up this morning and had about 95% charge, rather than the usual 100%. I'm assuming this is the result of power output for Relax and Sleep cutting int power input from charging.
I've also been in the habit of leaving my EVO 4G plugged in while tethering. I assume this is also a bad plan?

MOST of this advice is 100% true.
The only part that is not correct information is the advice to not let it die. It is perfectly OK to do this as long as you don't deep discharge the battery... Example like let it die then not charge it for like a week or something.
The science behind this is the fact that lithium ion batteries actually have a nominal voltage operating range which is like 3.2 - 4.3 volts or something like that. Your device is designed to shut itself down when it gets to about 3.5... This is done to protect the battery from deep discharge cycles.
Letting it die is perfectly alright. Just make sure you charge it soon after.
Also, you don't need to use your PC to charge it. That is in no way necessary. Your device came with a wall charger for a reason...
There are safety features built into the kernel and cable to keep you from damaging the device during charge. Use the wall.. It is perfectly safe and faster / more practical.

Your battery will automatically cycle between 95%-99.9999% to prevent overcharge, so you're fine on this front. You probably just caught it on the low end of the cycle.
The issue with charging + tethering is that a phone draws more power when plugged in (ramping up processor, etc.), and tethering eats a lot of power. More importantly, both charging the battery and running the antennas for tethering generate a lot of heat. So long as you watch your battery temp (most good tethering apps will toss in a temperature gauge, although if you're using stock you'll need another solution), you should be fine, but heat is one of the fastest ways to kill a Li-ion battery.

Although a full normal discharge (phone powering off) won't kill your battery in one go, it's a deeper discharge than I would recommend on a regular basis. Things are built with margins of safety, but I don't like playing on the edge when I can avoid it. The difference between 10%-15% isn't too much either when it comes to my use-case either, so I'm content to bounce between 20/30-95 most of the time.

The only way the battery could be hindered via charging is if you do it for extended periods of time.

Yeah. I've read up on this stuff. More than 10 hours is called Overcharging. It's unhealthy for the battery and for the phone itself
The normal charge is just plugging it at any time and plug it out at any time.
And then there is healthy charge. You need to do this once a month or two.
Let the battery fall below 20-15 percent and then charge it up all the way to 100.
Also keeping it plugged in at 100% isn't recommended because we don't have smart charge (which basicly cuts of the power from the charger to the motherboard at 100% to prevent wear and tear like in some new high end devices)
Hope you find this interesting :3
Thank you. I will do some research on this myself too..
Maybe add it to the get started guide? ;3
so charge for a short time doesn't decrease the battery?
ex: charge from 30% to 50% is not wrong?

If you sleep less than 10 hours than its good. I do that when I go to school.
More than 10 is not healthy.
this becomes a problem esp if u use usb tethering
Modern firmware stops charging the phone when it's full, drains it a bit, and then will not send any juice to the battery anymore- it's pretty much impossible to overcharge unless you've corrupted or hacked out that bit of the firmware or you're overamping to begin with- or the phone and its firmware are poorly designed or executed.
This is also why your phone drops from 100 to 95% so fast when you start using it- it wasn't at 100% when it stopped charging; the firmware lies to you so you don't get mad and try to overcharge and destroy your battery or call customer service because it won't go above ~98%
Well then, I've had this phone for over a year and always charge it over the night (way over 10hours :I)
