If you want to wipe the battery stats so you can make sure you are getting 100% out of your battery use the phone till it dies all the way and it turns off. Then turn it on and use it to till it dies, and repeat that process till it will not turn on at all. Plug it into a charger and turn it on & boot into bootloader > select recovery > advanced > wipe battery stats > reboot system and let it charge for at least 8 hours with minimal use.
@kim, charging the phone for that long will not have any ill effect on these batteries. They use LiPo batteries which are extremely different from previous phone battery designs. Our phones actually have a programed system that will cut the charging back and turn it off as the phone battery reaches the max. Once it reaches the max the phone will not charge the battery. When you battery gets HOT from charging is when to be worried. Heat and overcharging (which is next to impossible) are the two biggest killers of LiPo batteries.

I only know this because i use LiPo, NiMH, and NiCad batteries in my Electric RC cars. Been into that hobby for going on 20+years.
Takes about 2.5 hours for my phone to charge fully from 0%
The battery ages, and the time it takes to charge it goes up. Perfectly normal.
if you take the battery out and shake it for about a minute it will charge faster.
Are you kidding? haha
yes lol was wondering how long it would take for someone to speak up.
I think it is actually healthier to charge the battery slowly. Fast charging heats the battery... 2-3 hours seems reasonable.
And of course, shaking does not help- without the ice

Your phone will be fine, there are fail safes in place to prevent over charge (and fire/explosion). Its just a "convenient" notification to let you know the phone is done charging.
On a separate but related issue, I don't suggest leaving it charge more than 10 hours at a time, since the battery keeps topping off the charge, and in my experience this degrades batteries a bit faster.

Constant topping up will shorten the battery life. Not something to be annal about but don't do it too often. It also does not mean you have to fully drain your battery before charging, nor that you have to set an alarm so you take it off charge as soon as it read full.
Wait, so I should not charge my phone en route from work to home? About a 30 minute drive... not enough to fully charge the phone, just enough so it doesn't die before I go to bed.
I thought batteries did not have "memory" and that you could charge them however.... is there a good source to read?
Constant topping up will shorten battery life?
Care to back up that statement with some sources?
Heat kills Lithium based batteries.
A quick rate of charge or discharge creates heat.
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
(From the article)
The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible.
should be balanced with this (from the article as well)
batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem.
My recommendation is to keep the battery as full as possible at all times and do a full calibration cycle once a month. Done.
If you want the battery to last longer stretch the calibration to once every two months... However the phone will be obsolete before noticeable shortening of the battery life from doing 30 day calibrations. PLUS THE BATTERY IS REPLACEABLE ANYWAY. So, honestly, who cares?

If your battery overcharges and fails, your battery is a danger to you and everyone around you anyway; no matter what charging methods you use. A properly working lithium ion battery cannot be overcharged.

I have NEVER EVER had a phone that took so LONG to charge up!
Is it just mine? Maybe it's defective? What on earth did they do?!
Takes probably like HOURS to get to 100% with the screen, bt,wifi OFF!
And what's crazy is that after the phone says it's fully charged I unplug and the battery meter drops to 96-97%%. THAN it takes more time to get to 100% again.
If I didn't like this phone so much I take it back so fast!
Does you phone take really long to fully charge?

Really? Didn't know that. Can I get a faster charger then? I'd rather my batter charged in 20 min and have to get a new battery every couple months than have to wait nearly four hours.
Other than that I'm loving this thing.
Do you not charge it when you goto bed? When I wake up mine is fully charged. I don't check to make sure its 97% or anything like that, but when I goto bed its been known to have around 70%.
Of course mine is coming off the charger at 6am and I normally goto bed around 10:30-11:00pm.
As for charging a battery for 20minutes and having it full I've never seen that in any phone I've ever owned. You could buy a quick charging car plug, but personally I wouldn't recommend it for charging all the time.

Well I'm coming from a old phone that would charge to full in about an hour and be functional for 3 days. I didn't expect that with this phone (with the sweet screen and processor) but I am barely making 24 hours. I don't have GPS or Wifi on all the time and keep my screen on a low brightness setting. I AM playing around with it all the damn time though.
Anyway a normal charge at night works most of the time but it's good to know I can get a faster charger for the times when I need the power right away.
Also, any way to see the battery usage for the life of the device?
That's a smart phone for you. Never had a smart phone that would last more than 2 days tops, and that's with light use. But with moderate to heavy use,a day is it, maybe even a quick charge in the afternoon depending on how heavy the use.

Charging to 100% will not shorten the battery life if any Lithium Ion or lipo battery, but if you discharge past 5% will kill the battery faster. This I know from using the lipo battery's on my big RC Helicopters and that the ESC's have a low voltage cutoff on them to keep from doing damage to the battery. All lipo batterys are built the same so before someone says it is not the same, YES it is!!!

Already posted, and already shown that it doesn't work...battery still only charges to 96-97%
And there is an issue with the firmware in the Nexus S that prevents it from fully charging to 100% (incorrect voltage cutoff level?). This is NOT a deliberate way to "save" battery life.
Charging to 100% does NOT harm the battery or shorten its life in any way. Li-Ion batteries work best and have a longer total battery life when topped up to 100% regularly.

i believe i heard 2.3.5 will fix this and many other issues we are having.
Another way to fully charge your Nexus S is by switching it off and plug-in it to a wall charger until it finish charging (you will notice that by means of the white battery icon that will show up if you press -just a single touch, do not keep pressing- the power button). Every time I charge my Nexus S this way I get a full 100% battery charge.

ive done this and i never reach 100%. the highest i have gone is 98%.
This is curious. I usually pick my phone in the morning and read some tweets and news before I get up, while the phone is still connected to the charger. When I 1st take it it has about 96-97% but after I use the phone for some time it goes up to 98 or 99%, but never got 100%.
does that 5% really make that much of a difference? maybe it helps the battery to not go to 100%, maybe it doesn't...
but are you really using the battery down to 5% before charging it where it makes that huge of a difference?

if you leave the screen on while charging, you can charge it to 100%, i do it a few times a week. as soon as the screen goes off over 95%, it will stop charging, at that point just unplug it, then plug it back in and leave the screen on. itll get to 100%. have patience, itll just takes some time.
Is it possible to ruin my phone's battery due to overcharging? I charge my phone overnight no matter what percentage it is on, I still charge it I know this is bad, but can this ruin the battery? thanks
You should be able to charge as long as you want w no problems as long as you're doing this in a cool or room-temp environment (rather than say leaving it alone in a car charging at high noon w AC off, windows down & no sun shades on the windshield). If you have your phone charging in hi-temp conditions too long\often your battery swells & you get gradual irreparable damage.

If u make a correct use of your battery it won't get damaged. Extreme overclock, overvolt, etc can ruin your battery, but if u charge it every day because ur battery is empty it's ok, and u won't have any problem.

Normally, when your phone reaches 100 % full battery level, it stops charging and starts discharging. At around 95 % level, it starts charging again. This all takes a toll on the battery, especially over a long period.
If your phone's battery is at or above 50%, leave it alone or turn it off for the night.
I have an external battery pack for use during the day time, just for situations like this.

I don't think that's correct. It should switch to a trickle charge, which won't harm the battery, not stop charging completely.

It'll automatically stop charging itself when it's full, it's impossible to overcharge a modern cell phone battery these days. They are a bit more computerized than the old nicad batteries from back in the day. It's actually healthier to give lithium batteries partial charges at a time instead of draining to zero percent and charging to 100 percent.

How do you know your battery is getting worse if it's always charging?
My personal experience is the less you charge it, the better it will perform. However, when you DO charge it, make sure you are less than 30% battery and charge it to 100% before removing it.
For me it's easy, I basically charge my phone at night when I go to bed and that's it. I easily get through an entire day on this phone, though I admit I usually only have about 2-1/2 hours screen on time (I mostly use my tablet when I am at home)
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 .

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.

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.
