I just got a Samsung Battery Charger/Stand with Battery & have just charged the new battery with it, swapped it for the old one that had just run out when I noticed something weird...
The new battery was showing up as 100% for about 15 minutes. During which time I had the screen on for 3 minutes at full brightness.
What does that mean??
I've never seen 100% for any more than a second after I've unplugged the phone.
I'm assuming there's some difference between the batteries and the stats that are in the phone for the battery. I've used the Battery Calibration app before, when changing roms on my old phone, and that would sort out little anomalies. Do I need to use battery calibration every time I switch batteries?
Will this work itself out?
Will this swapping negatively affect my phone in anyway?
I thank you in advance for your help/suggestions
The phone has logic to not let the battery charge to 100% for too long. The charger does not. Battery calibration apps do nothing.

So... the charger over charged the battery?
Will that damage it?

I posted the same thing in the morning on another thread. Great mind think alike! Haha
Well to me it doesn't mean anything wrong really. Just that the phone doesn't fully charge the battery for safety or maybe heat reasons. Who knows? If samsung desktop charger is approved by samsung its good enough to me.

Guess your right.
So yours was saying 100% for unusually long as well?

It did on my new one for about 5min. Only but I had wifi on and screen and doing some work. It Wasatch new battery and didn't think much of it. I would say that even that was way more than the immediate 99% once off the charger on the phone

Just read your earlier post. Seems strange that the external charger charges more than the phone. I guess I can't complain about a few extra minutes!

I don't know why my phone can only charge to 99% of battery, this is my second charge already and the first charge also can charge to 99% only
Anyone have same problem ?
Just leave it on the charger. Once it reaches 99% charging reduces to a trickle only. This is by design and not a fault. If you charge overnight you should find it at 100% in the morning .

This is renowned in the official samsung roms of the galaxy series. Do not concern yourself, there is nothing wrong with your phone.
so the best thing to do is to leave it like 1 hour on the charger? I find it annoying to .. If it says fully charged and remove the charger it should be 100% and not 99..
Thank you so much. But when my phone charge reach 100% and i leave it continue charge 2 hours more already and it still show 99% right after i unplug charger.
Don't worry about it at all. There is nothing you can do for it to say 100%. No matter how long you leave it on the charger, once the phone says it's at 100% and you disconnect it will drop to 99%. It isn't a fault, it's what samsung does.
If you want to be really nit picky, you could say that within a second of disconnecting the charger, the phone technically has used some of the battery to stay on, no matter how minimal, so 'technically' with some tiny tiny amount of battery used it is no longer at 100%

Thank you, acttually i came from ONE X, my ONE X take 1 hour to drop from 100% to 99%.
So there are no need to worry about it now. And my S3 battery was great. It can last from morning to night with heavy usage.

Leave your phone on charge, go to CWM wipe the battery then reboot. It should go back to 100% shortly. That's what I did and it worked!
Reason why it really doesn't charge 100% is to protect battery as li-ion batteries should never let completely empty or full as the battery can die.

Mine charged to 100% and never have this problem with my S2
This is frustrating isnt it!
Also has anyone else found that it takes longer to charge than other phones? I.e. my S2?
Im presuming this is due to the bigger capacity battery
battery can only ever be 99.999999999999999999999999999% after you unplug the charger!!!!
not another one....

Mine charges to 100%, dry wiping battery stats. Though to be honest. It drops to 99% the instant I unplug it.
To avoid my OCD, I just disabled the percentage/1% mods. LOL, it makes me too obsessive.
Mine charges to 100% but drops to 99% within 10 minutes. Need to disable percentage display as well asap lol
I have read much about it. It is probably intentional. to save battery or something like that. Do not be so angry about it 99% it the new 100% haha

Battery only charges to about 95% when it is reading 100% anyway. This is for the health of the battery, can't remember the technical details though.

It's been well documented on these forums that the phone won't fully charge to 100%, mine actually charges to 100% but when unplug the charger it goes to 98%,,tried to calibrate the battery but no joy, am i to assume it's only Samsung who can provide some update to fix this or is there an alternative method does anyone know?
Bit disappointing as i cant say i ever had this problem with the SGSII although not taking anything else away from this superb phone.
These phones don't charge to 100% anyway to preserve the longevity of these li-ion batteries.
They charge to 96% or thereabouts.
The 100% in the status bar is purely for show.

I've noticed the same thing. When I first got the phone it would charge to "100%" then drop instantly to 99% when unplugged, I figured it was a way to increase the longevity of the battery and reduce the risk of overcharging.
But now I'm not so sure on that, it charges to 100% but drops to 98% straight away, not 99%.
For those saying it's a "feature", I find that hard to swallow given that the % is decreasing. I think it's more likely there's a bug in the firmware with the battery meter. Hopefully Samsung sort it out soon.

This is not true, my SGSII charged to 100% and stayed at 100% and didn't just drop to 99% or 98% so there has to be an issue here, not a feature at all certainly as far as Samsung are concerned.

The UI showed it as 100%, but it wasn't ACTUALLY 100%.
Maybe on the gs3 it compensates for the 4% difference faster, who knows.
Its not a problem and nobody is stealing your power so don't worry about it.
If you are getting bad battery life/excessive drain then you have a problem.

why did the SGSII charge to 100% and stayed that way for over an hour sometimes longer on standby before it dropped to 99%, how can the Galaxy S3 not do that, it has to be a bug no doubts about it, unless you can show me substantial proof from Samsung themselves i refuse to believe it.

Well if your battery life is fine then forget about it. Would you rather the phone showed 100% even though it wasn't at 100%?
It probably just compensates the difference between 100% and actual charge faster to show true battery life faster.
Even if it is a bug your battery still has the same amount of charge in it so what's the big deal.

As i said that is not the issue, if it really is 100% then it should actually say 100% and not any less, it's like if you walked into a bar and the barman poured you a pint with a massive head on it but when that head went down after a few minutes it showed as a bit less than an actual pint, same difference mate, if your paying big bucks for a high end smartphone you expect these type of things to show correctly, im not gonna lose sleep over it but undoubtedly it is a bug that they should really fix.
The phone does charge to 100% but will then start to discharge back to 95% before charging again, being static at one level for too long reduced the overall life of the battery.what I have been doing is unplugging my phone first thing in the morning and recharging it again for a few mins

I was under the impression that these batteries never charge to full capacity as it reduced the lifespan of the batteries.
Not sure where I read it but I'm sure that's what it said. I'm not doubting you but I'm just confused. When it charges to 100 back to 95 is that true 100% battery capacity?

Samsung do need to provide a firmware fix for this, it's not what one would deem to be a massive bug but is one nonetheless and if it worked ok in the SGSII it should work the same in the Galaxy S3.
I assume Samsung will provide a fix for this at some stage, but to be honest given their track record id expect someone on XDA to come up with a solution sooner:good:
Mine charges to 100%. Once it reaches full charge, unplug the charger and the plug it in for another 10 minutes. This will ready 100% after unplugging. My GS2 was the same way.
ive also read that the phones dont charge to 100%.
a simple google search will bring up this same dilemna from years ago.
Hey guys..
I noticed something weird on my galaxy s3. Whenever i charge my device till 100% and take it off from charger, it goes down to 99% immediatly. I thought it could be a bug in my current rom so i flashed another one. But the buf still exists. I even changed kernels. Still same problem. I am running latest foxhound rom
+franco r5 kernel right now.
Is there any solution for this bug?
Hope someone can help me.
Best regards

It is not a bug, that's how it is made.
If the phone charged to 100% and sat there for a long time, the battery would lose charge cycles and life faster. So what it does, is one of two things:
It will either NEVER actually charge to 100%, or
It will charge to 100%, take itself off the charger to about 95%, and then charge again to 100%, over and over.
HTC does the second one, I think the S3 does the first.
Thanks for the answer.
I didnt know that. Its just so weird because on every of my previous phones the battery stayed on 100%.
But anyways thanks

I know, I don't like it either haha. Some phones will even say "100%" right off the charger even if they're not actually at 100%, which is why sometimes you see people that take their phone off the charger at 100% and a few minutes later they are at 95, etc.
There have been a lot of questions about this in sammy roms, and also in the s1. And it got me thinking about it this way.
As soon as you disconnect the phone from the charger it's dropped to 99%. But in my head, I say it has had to have even used the most minimal amount of juice and is 'technically' no longer at 100%.
Some are saying other phones are reporting batteries on 100% for up to an hour after disconnecting from the charger. That might look great, but there is no way that is correct either, because it has to have used some juice in that hour.
Maybe samsung don't like pandering to the needs of the masses re battery use reporting. Maybe sammy is the only one reporting a correct level.
Me, I don't care. My phone lasts just fine. Are you getting better battery life than your last phone? Haven't I read that the 1x has ordinary battery life? Does it's percentage stay at 100% for a long time? If so, that would be a bit of a rip off to me.
I know sammy have included the option to show the battery percentage within the settings of the s3. I don't use it, and my battery indicator stays at 100% until the battery reaches about 90%. Works for me.
Batteries never charge to 100% anyways to avoid the battery over-charging and exploding

Hey, so is it a good idea to charge overnight? I've heard that the charger may overheat and melt the usb port or something like that. So do you guys charge the phone overnight or not?

Its a bad idea.
usually ppl do keep their mobile phones on charge at the night and unplug it off at morning.

I don't think the phone will overheat if your not using it at the time but it can shorten battery life a little leaving it on charge for longer than necessary, mine doesn't seem too bad with this setup I'm on now my temp never goes over 35° but before this setup i was getting temps of up to 55° when charging and using the phone at the same time. Don't think thats what caused my problems i told you about with chargers burning out though as the last one happened just as i plugged it into a cold phone.
I've always charged every phone I've ever had at night and haven't ever seen battery life go down on any phone i've owned. Not saying i recommend it but its never caused me any harm.

I have charged my phone for 8 hours over night EVERY night since I bought it (beginning of March), and the battery life is excellent.
Last time I looked at battery stats (yesterday) I had 1d 16hrs time on battery and 3hrs 53mins of screen on time, with normal usage.
My normal use is: about 1 hour music, 1.5hours internet browsing, texts, calls, flashing zips etc
So in short, with my experience overnight charging doesn't harm the battery at all

you can charge your phone all night, on condition that you must ensure your phone chager is original, if so, you can do it, as the original chager can adjust the voltage of the phone battery. if not, it is very dangerous to your phone.
Just got an S3.
Do you have any pointers to charging and battery practice tips?
Battery came half-full. I charged until full, it just turned 100% and green led.
I now intend to use it until drained, then charge it back up overnight.
Does this full/drain cycle sound like a good idea to you? Would you have drained the battery from new to empty? Same thing, right? As long as there is a pattern to touch the empty and full ends?
No point in those first charges. Mine came at 40% and when it went to 15 I charges it. NO problems or whatsoever
