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?
it's normal on a Samsung phone. There is no fix. Sorry for the bad news.
*previous Vibrant owner*
Thanks for the reply. It doesn't bother me as long as it's normal, just wanted to make sure nothing was wrong.

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.
Read this article, and it will help you understand why.
Dont know why someone would blame samsung....

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.

If it's a Samsung phone, it's the norm to blame Samsung. Not Google and Samsung, just Samsung. I know, it doesn't make any sense to me either.

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.
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 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.

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.

Just as much as any other battery, its best to let it drain and recharge.
I mean when the battery is low you can just connect it again to cable so why keep it connected constantly.
It wont hurt your battery but it will make it weak eventually after a long time.

There actually was a lengthy discussion about this that I read a while ago, I think it was on Ars Technica. Anyways, the point was that most modern batteries actually suffer the most when they're full or when they're drained almost empty; it's best to charge the battery often by small amounts rather than charge it seldom and from zero to full. In other words, they suggested that when the battery reaches 40% you should recharge it to around 90% and avoid draining the battery completely.
I just found something relevant on Gizmodo: http://gizmodo.com/5761317/how-to-take-care-of-your-li+ion-battery , or the whole article on Ars Technica: http://arstechnica.com/gadgets/news...-is-the-best-way-to-use-an-li-ion-battery.ars
From the article:
• Do not let it run out completely all the time. Full discharge puts a lot of strain on the battery
• Do not keep a Li-ion battery fully charged all the time, either. If you don't use your battery it might suffer from capacity loss

That is just too funny! Perhaps there are more girls in the forum than you realise and being properly dressed before entering is a new standard for you?!?
actually from experience with drills with li-on batteries i am sitting on 4 that are garbage right know dont let them drain completely and carefull with the heat the heat will eat them up.......also dont leave them charging all the time let them run there course as needed but dont let them drain to nothing and keep the heat to minimal...they do good then......;-}
My experience with Li-Ion batteries(which is not quite the same as the lithium polymer batteries in out tablets but probably close enough) is that they do better and last longer if you don't leave them plugged in. I have a number of Li-ion cordless impacts and ratchets and have gone through more than a few battery packs by leaving them on the charger over night. As far as discharging them completely goes, I assume its probably not a good idea. On a side note, Ni-Cad batteries actually seem to do better for me, they are just a lot heavier.
This may be the chicken or the egg question for electronics. Never really got a consensus on an answer. My laptop has gone through 3 batteries each being used differently (on the third now). I have read to charge when possible when less than 30% and to top off always since the batteries have a recycle life. Also to monthly cycle the battery to give the battery a proper exercise. Then if you are not going to use it discharge to about 70% and store in a cool place. Some even say the freezer.
Don't know how much the storing applies to the tablets but id sure like a scientific answer aside from batteries university or what ever that site is.
Well I for one would like a picture if you're going to store your tablet in a freezer.
Google "lithium polymer battery care". This will give you more than enough to get completely confused.
This is a good site: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries

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.
Hi guys, I've got this phone passed down by my mum. It's an old Samsung Note 4 but it's still working fine except the battery readings are totally out.
When I mean totally out, it's like switching off when it hits 30%. Sometimes it keeps going on after it hits 0%. I tried keeping a battery pack on it but it'll just do the same thing.
Just like to know if it helps getting a new battery or is there anything I can do to 'reset' the battery?
Thanks folks!
When a Note 4 shuts off at 30% that usually means that the battery is toast. Get yourself a new Anker battery for $16.99.

Like previous stated, battery is most likely going bad. But I figured I give you an alternative to try first. It won't hurt.
Power off your phone and charge it to 100%
Turn it on.
In play store search for "Nema battery". The first result should be it. It's called "Battery Calibrater" and is by Nema.
Install it. And follow directions.
Most all battery apps are crap. But a few people told me this really does calibrate the phone.
Also take note of what amps capacity it says your battery has.
It maybe worth the try.
Thanks buddy, I'll give it a shot.

That's the voltage. When it's plugged in, it'll be close to 5v. Unplugged it'll be lower.
That app might not have the reading I'm thinking of. No matter, you can try it.
Just for comparative proposes, I just installed it. And yes mine also shows 4300mv max.
But unplugged it's showing 3995mv, I'm at 75%.

I see.
I think a different figure shows up when I charge it turned on or off. If I hit 100% charge, it'll show up with less than that when I try charging it turned off.
I'll try the app once I get to 100%. Is that 100% referring to the phone being turned on or off while charging?

They mean with it on.
I only suggested charging it off. Cause it's suppose to charge fully better that way I guess. You'll be able to tell when it's fully charged that way. Either way probably won't matter for your case. Cause it's either gonna help or nothing much, then you'll know if you should move on and try new battery.

Yeah, you're right, last ditch effort to see if the battery works.
Another strange behavior is the speed of charging. I use the same charger with the same cable for this test. Funny thing is sometimes the battery takes ages to get to 50% from 0% but on good days, it gets from 0% to 50% in a snap.
Is this behavior of a faulty battery? Or am I dealing with a faulty circuit board? I'm on stock ROM so it's easier to troubleshoot.
