battery charged message at 95 or 97%?
defective battery?
Yeah me too. The only way I can get the battery to 100% is by using my spare battery charger. Trying to charge it in the phone always results in it maxxing out at like 96.

Yep..same here. I get it to charge to 100 by taking it off the charger for just a sec then putting it back on.

same. Usually 97%
Picked up a new charger, and it goes to 100% and beyond, and the LED light never turns blue!!!
Seems to charge faster, that extra .5A must be helping!
I mostly charge my phone when it's off and I always get 100%
Have you let your phone completely die yet. I had the same issue and really bad battery life (like 5 hours max). It helps to let the battery completely die every few days. Before I let it die the best I got was 97%. Now I get 100% all the time. Also my battery last closer to 10-12 hours, depending on use.

Yes, mine stopped at 95. I tried charging, turn off phone, put on charger for an hour, then turn on, got to 97. Traded batteries the same.
However, one reading says 100, one says 97 - the batteries have issues is all I can figure out. Might be internal software.
Normal for lithium-ion batteries and modern chargers.

so htc hero and palm pixi arent modern? cuz they dont have this problem
What is the purpose in doing this?
On to my real question
So anyways I charged my phone to 100%, removed it from the charger and wiped battery stats, used my phone and let it run all the way down and it turned off before I put it back on the charger. From reading you are not supposed to let it turn off. So should I do the process over again?
Thanks.
When I do the batter calibration I let it die completely and that's what it says everywhere so I think you'll be ok unless you really don't see an improvement in battery.

Seriously.. I think the USB charging port is bunk.. I brought the 2 batteries and a wall charger for 9.99 on ebay. I would always have to top off the batteries to they stay full charged...
With the Wall charger.. it's a way better way to charge. I"ve done 4 charge cycles.. and every time I plug in a charged battery off the walll charger it's stays fully charged for a long time.. then it trickles down... I serioulsy don't think calibration is the problem.. it's the USB charging port. There shouldn't be a need to Calibrate your battery.
Just my speculation.

i think he is talking about calibrating your battery in use with a new custom kernel, in which they recommend to calibrate battery.
to answer your question though, like you already know i did the same thing. the response i got from that is that it should not matter.
also i too got the 2 battery deal and wall charger for 9.99 and can deff say using a wall charger charges your phone way better than the included usb charger.

What is this two battery and wall charger?
For the kind of batteries we use in the cell phones, it is never advised to let the battery drain completely - this is stated in the manual that comes with the phone, too.
I believe it is wrong information that the battery needs to be drained completely in any case. Draining the battery completely actually reduces the storage capacity of the battery.
If you have more than one battery are you supposed to do the battery calibration for each one?
Can get our batteries to charge faster? Or is there really no way....
Thanks for your responses
Use a more volt charger? Idk
charge it while it's on 50% or more. lol
the external charger from samsung charges faster than charging it on the phone.

From what I understand, faster charging equals shorter battery lifespan. I'm sure it's possible though.

Usually when im charging if I reboot my phone while charging itll boost the charge some.. don't know why, but I usually gain about twenty percent or more at the least. Also charging it while powered off is generally faster for me.

rebooting it could change the battery estimate, which is what "conditioning" the battery really does-- it changes how the battery level is estimated by the system and not how the battery actually charges.
I'm guessing that the reboot causes the system to re-estimate.
It's inaccurately boosted and if you take it off the charger at that point it will drain extremely fast.
Reason being is this phone charges slow compared to others
I bought 2 spare batteries and a charger. Ebay from China. Very cheap and works like a charm.
Yes. Its possible. You would need a new kernel.

I remember as a kid, when getting new hardware, you need to charge it to the maximum and leave it in for a few hours to kinda work the battery and get the most optimal battery life. So for this phone, what would you need to do when you first get it to get the battery to be the best it can be?
Do we cycle it from 0 to 100, or just charge it to 100 and leave it?
Or does it not matter?

It doesn't matter. While older nickel-cadmium batteries could have issues with charge memory, lithium ion batteries are not affected. Just charge and use your phone as normal. If you want to maximize battery life make sure not to place your phone in extreme heat (eg. inside a locked car in summer time) and avoid leaving your phone at 0% charge for any length of time.

Same thing. Either way they don't have the memory issues that old rechargeable batteries had..

Nope.
These new Lithium batteries aren't subject to any of these myths.
Same with the "Take off your device from the charger once it has been fully 100% charged or the battery will stuff up." Nope. The battery just cuts the charge and just runs down. That's why if you look at your charging history, it might go to 99%, 98 or even 97, and go back up to 100% because that's when the phone decides, "Yep, I'll take a bit more charge."
Alright. Thanks to everyone!
I'm getting mine tomorrow ;D
(Aw, outta thanks to give :'( )
It is good with these batteries to run then down to almost empty every week or so, right?

Another myth. Not true for Lithium batteries
Really? I read this in a battery forum years ago. This was for laptop batteries though..
Not meaning to sound sarcastic, how do you know this? Are you an electronics engineer or something? Just wondering.

Lithium-ion/lithium-polymer batteries don't have the "memory effect" that older nickel-cadmium and nickel-metalhydride batteries did. So there's no point trying to run your battery down low every now and again to help its life. In fact, it seems that charging it more often is the most helpful thing, i.e. lots of small charges rather than big charges all the time.
Just use it normally and charge it when you need, it'll be fine.

How about leaving the phone charging after it is fully charged? Like when you charge it overnight.

The phone and charger electronics will lower the rate of charging as it reaches 100% and turn it off when it's done. You don't need to worry about unplugging it right away.
In longer term storage situations where you aren't using the device (i.e. weeks or months) it's optimal to store the battery at a charge level of 60-70% to reduce battery degradation over time. When the Mars rover \Curiosity was en route to mars the batteries were at 60% and were charged upon approaching the planet.

I am an electrical engineer actually. Li-Ion or Li-Po batteries do not need to be treated any special way. The only thing that degrades them is use and time. And it does not matter how deeply you discharge them (discharging to 50% twice is about the same wear on the battery as discharging to 0% once, within a reasonable degree of error).
What you may have been reading was with regards to calibrating your laptop's battery meter. There is some truth to that, and allowing even your phone to discharge completely (down to 5% or so) once can help make sure your battery percentage is accurate. But it does not affect your battery life at all.

Actually, it doesn't say to do it "first". It says "its a good idea to fully charge *as soon as you get a chance*."
The wording in the quick start guide you provided doesn't seem to imply that its a critical thing. It seems to me that they are putting that there in case someone takes it out the box, starts playing with/using it, then wonders why the phone is already dead. Then they post to XDA about how the battery life sucks. (Just kidding! )
I generally try not to charge my note 2 overnight. I want this battery to be healthy as long as possible, so I don't want it to sit at high voltages for too long.
Normally my note 2 is around 80 percent when I go to sleep so I don't plug it in at night, I just plug it in in the morning for an hour before going to work. It reaches 100 and then I remove it.
The times when my battery is much lower that I won't be able to charge it in the morning in the hour, I do charge it overnight.
What I've noticed is that the battery drains much slower on the days it's been on the charger overnight.
So I'm thinking that the charger will continue to raise the voltage even after it reaches 100%. Maybe someone has some other thoughts, but I just wanted to share what I've noticed so people are careful with their battery.
Hi,
Charge it yhe way you want. Don't stress on it.
But for a few tips:
Don't let the lithium-ion battery go down to critical battery levels before charge.
Don't put the battery on the refrigerator.
Don't over charge it even if it's a new battery .

So basically i can't charge the battery overnight? I don't understand the meaning of don't overcharge it.

You can but can potentially damage the battery. It's up to you.
I'm going to disagree with you guys. The charger and the battery has overcharging protection built in. So don't speculate with overcharging overnight. In fact when the phone has stayed longer on the charger I got better battery life. Cheers

Yes, I know. So why would you charge your phone overnight? So it would stay 100% when you wake up?
I charge my phone overnight everyday.
The battery magnet would trigger the charger into trickle mode. This prevents overcharging.
Li-ion battery prefers to be charged then discharged. Contrary to hearsays, discharging it to critical levels too often would actually degrade battery life.
My Nexus one of 2 years still maintained a 84% charge because of this.

Cause i'm using it all day till 1-2 o'clock at night and thats the only time i can charge my phone. And with the heavy usage im putting it the battery cant hold more then 15-16 hours

The battery have both overcharging and undercharging protection.
So there is no problem charging your phone overnight, the battery will stop charging when it is full. It will then be allowed to discharge a bit and the charging cycle will resume. The fluctuations caused by this charge/discharge cycle are usually hidden by the firmware so that you only see 100% - charged.
As for undercharging, it can indeed kill batteries, but it won't happen unless you drain the battery completely *and* let it self-discharge for a few weeks.
You don't have to adopt a specific charging pattern to keep your battery in good shape, just do what's most convenient for you.
Some tips however :
- Avoid high temperatures, batteries don't like it. The fridge is actually a good place to store your batteries provided that you took the necessary steps to prevent condensation.
- Store unused Li-Ion batteries at about 50% charge. Fully charged batteries have a lower shelf life, the 50% are there to prevent self-discharge from causing undercharging.
- A full discharge-charge cycle won't make your battery healthier but it is useful to recalibrate the power gauge.

I see. Well, in your case it may be better.
Because during the night it gets more time to detect the proper voltage and stop.
And the battery is removable for a reason. It'll have over 80% original capacity even after 2000 discharges and it's only $20 at most to replace. No need to stress it over. Use it all you want and replace it the time comes. Leave the stressing over to the non-replaceable guys.

You telling me if i charge once a day, the battery will still have over 80% charge after 6 years of years? I find that hard to believe as all my previous batteries have to be replaced after 2 to 3 years of use.
That's the quote from manufacturers under ideal conditions. The only devices that I haven't threw out for that long are laptops and the battery in them are still working flawlessly and holds a reasonable charge.
Even tiny LSD batteries can have up to 1000 charges so higher capacity ones will last longer and be more durable due to the increased amount of cells. Just like how higher capacity nand will last longer than lower ones.

It's a 30 battery. Treat it like **** and just replace it when it dies! By the time it's dead you'll be wanting a new phone anyway.
