Hi Guys,
I was wondering if this is nomal. When charging my phone it normlly charges and the percentage moves up in 1% increments. But, when I get to 92%-95%, it jumps to 100% within a minute or so. Is this normal? I am losing 5% of my battery capacity?
no you are not, mine did this the very first time i charged it

thanks, does it continue to do it? or it only happended to you during first charge?

Try unplugging it and plugging it back in right away. Is it rooted? Maybe wipe your battle stats. That's where I'd start.

I believe its purposely like that. Most phones does this so that your battery doesn't charge fully as that kills the battery life, therefore usually it only charges to 95 - 98% but will show 100%.
Kinada new to this. But
It is ok to charge the Samsung stock gsm battery at any percentage or should I wait till it low to charge it??
Like if I'm at 30% at night and need full battery for the next day, should I drain it to 10% ish or just let it charge from 30%??
Would it shorten the length of the battery or harm/damage the battery in any way??

doesnt matter with lithium.
Samsung Galaxy Nexus uses Li-Ion battery. So it doesn't matter if u charge it any way u like.

Does leaving the phone plugged into the charger all night degrade the battery?

yes it does.. overcharging the battery is not good. it may decrease its capacity. it is always recommended to unplug it when your phone is fully charged
- It is best to keep the battery between 20-80% and never fully discharge it except for the first time just for calibration
- It is preferable to use the pc for charging (slow charging is better)

What you'd stated is true but doesn't the galaxy nexus have its own safety for this where it stops charging and runs off the battery til it drops to ~98-96% and then charges back up ?

Is slow charging really better? In my experience, when charging from AC, the battery lasts longer than when I charged it from my laptop.

It should be better because its cooler also its more steady than an AC Charger
I just charge it at night before sleeping and unplug it when I wake up..taught the battery stop overcharging??

No, the charger will stop charging when the battery is full. If it didn't, an explosion would awaken you at night....
My GS3 takes about 3-4 hours to charge from 0% to 100%. I am on stock and am using the OEM wall charger that came with the phone. Is this normal?
Mine takes around an hour or two I believe it used to take around the same as yours but it doesn't last as long. But how long does yours last

Mine take over 2 hours from 5% to 100% using stock wall charger,,, 3 to 4 seen like a lot.
The answer is... it depends.
If you're charging with the phone on, it will take longer, if you're charging via a usb port, it will take longer.
If the phone is off and you're using the stock wall charger, you're charging at a maximum of one amp. If you have a stock 2100mah battery (2.1 amp-hours) and your charger is 100% efficient (never happens), the best possible 0-100% charge time is... 2.1 hours, it really is that simple
Now, you're not getting 100% efficiency, plus the way lithium batteries charge, at around ~50% capacity, the charge current steps down gradually from 1 amp to nearly 0 amps, so your real full charge time with phone off is probably going to be closer to 4 hours than 2. The step down is necessary to avoid over-charging. The logic (usually in the battery itself for phone batteries) to determine full charge is when the battery reaches 4.2 unloaded volts. Charging current will increase the voltage reading, so as it gets closer to full, charge current is gradually stepped down to maintain the 4.2 volt full charge state. As the current approaches zero and volts stay at 4.2, the charge controller knows that the battery is full.

3 hours is the average using the included 1amp A/C charger.
Charges 10% about every 15 minutes for 0% to 90%, and charges the last 10% in about half an hour.
(don't bother trying to charge using your computer's 0.5amp usb port, though; takes forever, especially if you're using it while charging)
There are reports that the charger that came with the s3 is garbage.
I was using the s2 cable to charge and it took approximately 1.5 hours.
Now it's taking 3 - 4 hours.

The charger that comes with the S3 is NOT garbage. I tested charging times against a "better" 2.1amp charger about a month ago and there was no difference. (If your custom kernel supports "fast charge", then there'll be a difference, but your battery will suffer. Better to stick with 1amp)

That doesn't make any sense. I think you're just not remembering correctly. Test again and report back.

Flashed JB today. Phone currently charging. Started charging at 2%, now at 41% and it's been 45 min. Estimate completion time, 1 hour 45 min.
So the culprit is not the USB charger, but rather something I had installed on ICS. I suspect it is the launcher I was using, which was GO launcher. Prior to JB, i was using apex and it was charging a little bit faster than GO, but still wasn't acceptable. I think it was 3ish hours for full charge.
My current JB setup is pure stock launcher and apps.
With stock charger it takes my phone approximately 2.5 hours to go from 5% to 100%.

I can confirm that,my AT&T S3 has been charging with that charger for 6 hours and I am still showing a 50%,so I had to grab a Motorola charger and it went up from 50% to 73% in half an hour.
Freaking Samsung,there's always something.
I'm on Slimbean 4.2.1 RC1 w/ lean kernel and my phone will usually last (with average daily use) about 3 days on one charge. The rom/kernel supports fast charge so I can get it from 0-100% charge in under an hour and a half. On stock rooted rom I was getting maybe a day and a half of battery life. Darned AT&T bloat lol

So how do we decide the most efficient charging method possible? How do we look at the Amperage of the battery and the amperage of the charger and decide what's best?
Also what's faster? Wall charging or fast/quick charging to a USB line?

Fast Charge will make it charge the same speed the wall charger would (but breaks storage mount while it's turned on).

:good: I started charging my s3 at 8:30AM this morning. and at 5:50PM it's showing 96% charged. taking 9 HOURS! to ALMOST CHARGE?? I ALREADY REPLACED THE BATTERY ONE TIME WITH ANOTHER ONE. BOUGHT THE PHONE NEW FROM METRO.
SO MAYBE YOU ARE RIGHT THE CHARGER IS GARBAGE. I WILL TRY ANOTHER WALL CHARGER AND SEE IF IT WILL CHARGE FASTER.
THANKS! FOR THIS POST!

This doesn't mean you battery is "on charge" for all the time... once the battery is 100%, the charge changes to something called "trickle charge". At this point charge does not happen continuous, but like a trickle to maintain the 100%.
Pull the phone out at the end of 8 hours of charge, and notice how quickly it goes to 99. Pull it like 10 mins after it says full, and it takes longer to go to 99%.

Higher amps charge battery faster... but... at the cost of capacity... At approximate 10% more charge than the battery is optimized of, it kills the battery by as much as 30% sooner. So its not really worth that. At the same time lowering the amps by 10% increases life by about 20-30%.

Only in charge time. Regular charger can take 3-5 hours to charge. Quick charger takes 1 - 1.5 hours. Battery life (in terms of SOT) is the same.

It was charging really quickly but discharged equally as fast when I unplugged. Now going back to stock charger but issue remains. Is my battery gone for good?

Screenshots or didn't happen. Like what does "discharge equally as fast" mean? You only have 2 hours of off the charger from 100% to 0%?
Went from 100 to 30 in just 45 minutes of browsing and YouTube I kid you not. What should I do?

I would try it again, take screenshots when you're at 100% percent and are down to 30% or lower, and if it happens again that fast, don't use that charger anymore and see if the stock charger fixes it. If you still have terrible battery drain like that, see if Google will replace it. You would have proof with screenshots. I wouldn't mention using the Aukey charger of course.
