Hi all, I have a quick question. I have read in various forums that leaving my phone plugged in after its fully charged can ruin battery life. Does anyone know if this is true? I usually plug it in to charge when I go to bed and I know it finishes well before o wake up. Thanks
A question for mythbusters! In this day and age it won't harm the phone or battery...though some people disagree...I've always charged mine overnight...especially since the vibrant takes a little over 4 hours to charge!

That's what I thought, but I figured I would ask. Thanks
No problem leaving it plugged in overnight, according to this tweet from Samsung Service,
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?
If you leave ur wirless tethering on while charging, your battery will charge up to 100% and stay 100 even if you take off the charger.
I hope nobody posted this method already
Nice! Ill test that later today

charging it to 100% will shorten the battery's life.
I know but there were many threads about battery not charging up to 100% so I just decided to help a little)

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.
Thanks for playing today...

hopefully an OTA will fix these issues.
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.
Well, i got the phone today for christmas. When i powered it up and plugged it into the charger it waas 86% on the phone. I charged it to 100% then tried it for 10 minutes and i noticed that it went down to around 86%.. And i was like WTF so i powered it in again and now its still in there..
I thought that the reason for this is that its a new batter and never been fully charged so it have to be charged for several hours on 100% for it to be fully loaded.. Is this true or what can cause this problem??
Thanks alot in advance!

Let the battery discharge all the way before charging it up again.
It takes a while for a new battery to settle in.
By the way, nice Christmas present!

Hi. After downloading the "battery calibration" app from the play store, my battery started charging extremely slow. It went from 35 to 60 in three hours after installing this app. It usually would have been finished charging by then. After noticing this issue, I reflashed the rom (eclipse rom), but the problem persists. Does anyone have a solution to this? Will I have to buy a new battery?
I use battery calibration haven't had problems you maybe looking for issues since u tried something new the reason I say that is that it only removes the battery bin file like the app says when u open it if u charge fully use it and only once not suppose to use unless u flashed new rom. All it does is remove the battery stat file from os and replaces it with a fresh one so you don't have fake stats from last rom because different ROM's usually have much different battery life. So this would lead me to belive it cannot effect the power of charge recharging your phone that would be battery, cable, extension cord if used, outlet maybe post a thread on anyone with knowledge of battery Stat removal because most do it manually without the app because it's a good thing. So the app is just convince. Oh and recalibrate your battery drain it fully take it out for 2 min put back turn on wait for it to die. Then charge uninterrupted til full this let's the battery learn it's full capabilities like when I did this my phone turned on after I reinsert battery it said 0 percent and was on lol. So the percent wasn't accurate. Let it drain to 5 percent recharge fully try not to use it while charging it takes longer to charge. I hope I helped. Sorry your post wasn't answered sooner.

Never mind, the issue was already resolved. I forgot about this post. Thanks though.
