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.

Does anybody have access to a Moment,Instinct HD, Behold II? Charge your Nexus S to 95% and then put battery in one of these phones and see what battery reading you get.

Doesn't work...sorry.
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?

guys is better to charge the phone before it is <5% or not?
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.

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?

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 suggest reading up on how float charging works.

Does it will effect my battery?
I noticed that after unplugging my phone when it said it was fully charged the battery immediatley dropped to 97%. I found a thread in the Vibrant forum with people talking about their Vibrants doing the exact same thing. No one seemed to know what was causing it. Is anyone else seeing this with their phone? Should I be concerned?

Yep. From my experience I've discovered the following:
1. Keep it on charger for a extra 1 or 2 hour.
2. Charge it while off.
And you won't see that drop again. If you do one of those things.
It's normal on every mobile phone.
Here's an explanation.

It is normal, it was designed to do that to prevent your battery from burning out sooner thus giving you shorter battery life in the long run.
If you want to truly charge to 100 percent, you bump it. Meaning when it says fully charged(its lying to you), pull out the usb charger, then plug it back in. When it says 100 percent again, pull out the charger, put it right back in, let it charge a few mins more. Keep doing this till you get bored. Doing this bumping technique will truly charge it to 100 percent, and it won't fall so quickly, but it burns your battery supposedly in the long run.
There was an article about it. Google bump charging battery, or something like that.

Yup -- once the battery reaches full capacity the charger stops (to avoid undue wear on the battery). The battery will discharge down to ~90% before the charger kicks in again.
On Nexus One we were able to run off of wall power once the battery was charged, significantly reducing the speed at which the battery discharged once full, and improving the chances of it being 99-100% when you took it off the charger. Nexus S has a different charge circuit configuration which does not allow it to operate in this mode.

battery wont charge to 100%
I was wondering if anyone else was having a problem charging their Nexus S to 100%. I have recalibrated it by draining it then charging it while its off for about 8 hours.
Ever since I first got it would only go to 97%. I also tried to delete the batterystats.bin file and that's not working either.
If I bring it back to Best Buy should I relock the bootloader and get a new one or will they replace just the battery for me?
Thanks
I'm having this issue as well and am wondering whether or not this a prevalent or not.
Well I decided to do the thing where you charge all the way, turn off, charge again and remove battery stats, my battery wouldn't go above 95% charge even overnight. I decided to drain all the way and then remove battery stats, now it goes to 97%, any ideas? not sure if its just reading wrong or what.
keep reading, there must be over 40 threads about this
It is not reading incorrectly, it's just being honest with you. Please use the search function.

its only supposed to charge to 95-97%. its a feature to help preserve your battery. if you want to see 100%, youll need to bump charge it there or charge the rest of the way with your screen on.

What simms said, watching a couple YouTube videos or anything that uses the processor above light usage will make it charge to 100% but I don't know if that's good for your battery .
As for what I know, on Nexus S the maximum charge is 96%. If you get more charge, it can damage your battery. Most of custom ROMs already have this fixed (when it's 96% it would actually display 100%).

I don't know the consensus at this point, but people say charging all the way to 100% is bad for your battery (and there are many preventive measures in your phone such as discharging a little bit once it reaches true 100%). People also say the battery has a limited number of cycles so dropping it to 0% is also bad. Keeping it around the middle is best.

As long as you don't run it down to 0% and drain it completely, which is pretty hard to do, it should be fine. Li-ion batteries work in terms of charge cycles. You're going to shorten the battery's lifespan the same amount when you use up 100% worth of battery charge, whether it's by going from 100 straight down to 0 and back to 100, or charging and recharging constantly.
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.

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)
