What's the best way to charge the phone? Like do I charge the S3 to Fully Charged and then disconnect and then use it till it dies or charge it when it drops to a certain percentage?
The S3 uses lithium ion batteries. Try not to ever fully discharge the battery, it degrades the battery considerably. I would fully charge it whenever I get a chance (or up to 90%) then recharge it within the 20-10% range.

So don't ever let the battery drop under 10-20% or let it die, always charge it when I get the time to?
Can someone help me please
Doesn't really matter, you won't prolong the life of it notably in any case. And the small gains are definitely not worth the trouble.
Just use it like you want and replace it in 2 years time. It will have degraded by that time, however you use it (even if you don't use it actually)

You can use it to 4% actually before it's a huge concern. I charge mine around 10% or lower and haven't noticed any decrease in battery performance. Just don't kill it.

Will it damage the battery if the percentage for example is at 70-80% and I charge it for about 45 mins, it won't hurt it if I disconnect the charger but the S3 not fully charged?

No. It won't damage anything. Just know the more cycles, the more wear. Continual bump charging may shorten lifespan. Not what I consider damage.

Just don't let your battery fully discharge or get too low. Always recharge it as often as you can, especially in the range of 10-20. Also, don't leave it plugged in for to long when it is fully charged. Follow these three steps and you should be good.

If there's one way to send your battery to an early grave, this is it.
Modern batteries are limited by their number of discharge/recharge cycles. Letting the battery drop to 80% and then recharging is the same as letting it drop to 20%.
However, allowing the capacity to drop to zero is a stupid thing to do, since this permanently damages the battery. The battery has its own controller which goes some way towards protecting it, but it's a trade-off between shortening the lifetime and the actually runtime you can get from the battery.
So, to summarise: you're fine letting the battery drop to 10-20% before recharging. Do not allow it to fall below this too often, as you'll shorten the lifespan.

Yes it is 'bad' for Li-on batteries to be run down to zero. Ignore any posts you see saying otherwise.
Just charge it and use it. When possible, top up charge. Li-on batteries do not have memories and do not need to be 'conditioned'.

Hmm, my bad, my Apologies, seems there's some way to go yet for me, I assumed this was the case as I had horrid life out straight out of the box, these discharge cycles helped tremendously, though with that being said I tend to not leave it below 15% now before I charge.
Oh well, live and learn.
Never discharge the battery to less then 10-15% if possible.

Won't hurt that much. Contrary to what people say li-ion has limit on amount of recharge applied from whatever level it was applied. Also the phone cuts off before dangerous low levels are reached. However frequently doing this should be avoided.
The biggest danger is leaving phone in discharged state for long period of time as the background discharge (e.g. Power on off button, clock, etc.) will flatten the battery, without the protection circuits and completely ruin it; charging while hot (above 50 to 60 c) will also send battery to an early grave.

Entropy preaches this.
LiIon batteries don't like to be discharged to zero. Typically, don't let it drain it past 25-30% before you recharge. The "battery cycles" are referring to your typical usage and recharging habits. Basically a more technical way of saying, give it some time.

Is there a similar upper limit guideline? Like, are we not supposed to charge to 100% overnight? I've heard for all manner of phones/laptops that it doesn't matter that much if you leave it charging overnight because at 100%, it's smart enough to not draw any more power than to keep it from discharging. But then I've also heard that shortens your overall battery lifetime. So what's the rule of thumb on this for our phone?
I need to watch my drain more closely, I think I let it drop past 25% fairly often if I'm not at home, and even sometimes when I am DX

Note that "overnight" does NOT qualify as a "long time". This advice is referring to things like your video camera, which, after using it, you might store for weeks or months. Charge it to 40%, and put it away. If it's away for a REALLY long time, pull it out and recharge it to 40%, because you don't want self-discharge to kill the cells.
Doesn't the 20% rule seem rather arbitrary? If what I think I know about batteries is correct, % capacity as reported by the phone isn't based on the "actual" capacity of the battery. When the phone reports 0% charge, the battery is still supplying about 3500mV, and about 4200mV at 100%. So really, discharging to "0%" means discharging to about 83% of theoretical capacity. The 3500mV limit is determined by the minimum operating voltage of the phone's components, not really by the battery.

kill your phone and take a voltmeter to it. but yes, that should be the fact, I know little about Lion batteries, but electrical power is same in general.
whatever is required to run the machine must be met or it wont run. so its smarter to have our % adjusted as such. rather than having the phone shutdown at 40% battery because of lack of voltage.
Meh, in a year or two, I feel the batteries might start to deplete, but let's be honest, we'll have new phones by then =D

Current != Voltage.
Aka, the battery could still have 3.5 volts but no amps. And hence cannot power the phone. Volts will slightly decrease as the battery is discharged, but without any amps left it doesn't really do much good as a power source for anything...
Google "volts vs amps" or "voltage vs current" for more info.

I'm an engineer; I understand the relationship between voltage and current.
Current is not determined by the battery; it's determined by how much current the phone draws from the battery. I'm just saying that the current demands of the electronic components of our phone are too much to operate from a power source that's only pushing 3.5V. Hence, that's the artificial "0%" power level of the battery.
You're digging too deep into what I said though...my point is just that I don't think it's bad for the battery to let the phone discharge to 0%.

Dang. After reading this I feel like I totally raped my battery. One question, a little off topic maybe... Even though our phones calibrate the battery themselves, is it important to charge the phone to 100% before installing new roms. I've been doing this ever since I had my fascinate. Is this still necessary?
I got 2 questions.. i use 2 batteries in my phone, the one thats come with it (1650 mAh) and a replacement that i bought of 1800 mAh.. So when im using the phone i let the other battery charging and then i change them when one is discharged.. it is bad for the phone to constantly use batteries with different mAh? and the other one is that if it appropiate to do battery cycle when im using the 2 batteries.
Thought I would get an answer but that's what I get for not searching thoroughly.
Apparently we don't need to charge to 100% before flashing a rom. Although it is not recommended to flash roms on low battery (below 50%) to prevent problems,rom related I'm guessing. This is just from what I read. Please correct me if I'm wrong.

You don't. Ever, with one exception:
If you have a battery that has been sitting completely unused in storage for a VERY long time (many months, possibly longer), it may not perform well initially. Just 1-2 discharge/charge cycles of any sort will get rid of the passivation layer.

Usually they come about half charged so you'll be good for a few hours. The 8-10 hour rule was for older battery technology (nickel cadmium), the new kind (lithium polymer I think?) is much more flexible as far as charging schedules. I don't think you have to do anything special for the initial charge.

Honestly, when you get your phone (and once a month) you should let your battery drain completely (within 2% is a decent rule) and then charge all the way. Do this for 2-3 cycles and you battery will last a lot longer. This is true for any electronics.

not quite - the below is from Battery University in regards to lithium ion batteries (which is what's in the evo);
If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery.

And
Lithium-ion is a very clean system and does not need formatting when new, nor does it require the level of maintenance that nickel-based batteries do. The first charge is no different than the fifth or the 50th. Formatting makes little difference because the maximum capacity is available right from the beginning. Nor does a full discharge improve the capacity once faded. In most cases, a low capacity signals the end of life. A discharge/charge may be beneficial for calibrating a “smart” battery, but this service only addresses the digital part of the pack and does nothing to improve the electrochemical battery. Instructions to charge a new battery for eight hours are seen as “old school” from the nickel battery days.

If the phone's charge time is roughly 2-4 hours, what will charging it 8-10 accomplish?
The Sprint store opens and activates phones on the spot regardless of charge, which leads me to believe that--while some/most Sprint store Employees aren't very knowledgeable in electronics, I'm sure they would have been told in one of the many meetings they have that you need to not do this and inform the customer of needing to charge their phone for __ amount of time before using it.
At any rate I'm just playing along with the possibility. Of course you don't need to charge your phone any amount of time before using it the first time. Our battery technology has evolved to the point where trying to keep track of charge schedules is irrelevant and not needed. Seriously, if it were, they would have provided a small paper calendar with your phone so that you can mark when the last time you fully discharged it as well as instructions on how to care for your battery.

While this is accurate, I still always try to full discharge as often as possible. I do this because the phone reads battery information and calibrates the battery percentage based on that.
In my own unscientific research, it seems that frequent charging messes up the battery readings. I know that there was once an article about wiping battery stats being a placebo effect, but it really does seem to help when you wipe, full charge, full discharge. The phone always seems to last longer, but its likely because the phone is properly calibrating the max/min capacity of the battery accurately.

The batteries in phones anymore do not use memory in the actual cell. The phone itself does keep record of the battery to help protect it, and clearing that out and re-calibrating the battery by draining it can help, but doing full drains to the battery will just reduce the overall life span of the battery.

I recently purchased the Anker battery for my Amaze. I've done the suggested 4 full battery drains and charge, but I've noticed something odd. Right after taking my phone off the charger, the % drops pretty rapidly, roughly 10% in about 30 min, with almost no usage. The level continues to drop pretty rapidly till the % gets down to about 70%, where it seems to stabilize, and drop at a slower rate. Anyone else seen this issue, or know what might be causing it?

This isn't a problem with your specific battery, it has to with overcharge prevention.
Essentially, once your battery is fully charged and the LED on your phone flashes green, the phone's battery is no longer charging, and it is actually running on stand-by off of the battery. Perpetually trickle charging the battery would shorten the life of it.
As a result, the battery consumes some energy while the device is in stand-by, but until the device reaches 80% or so, it doesn't start to re-charge. Because it is still plugged in, the device is reporting a full battery, even if it has been running on stand-by for hours on that charge.
There are kernel modifications that can change this, but unless it's an issue for you, I would avoid doing so for the long term preservation of your battery.

I have two Anker batteries, bought at the same time. Both were conditions per instructions. One of them has great battery time, the other has very poor battery time. I think it is hit or miss with these batteries.
If you're interested, I think you'd be able to get that stabilization (after then initial drop) a little higher if you tried calibrating as per here. I'm at about 90 for the one I calibrated, 80 for the other.

Yes, I do that also, but this has not helped that 2nd Anker battery.

Perform shallow discharges.
Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit. The table below, from Battery University, shows that discharges to 50% are better for your battery's long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio).
Don't leave it fully charged.
Similarly, lithium-ion batteries don't need to be charged all the way to 100%. In fact, they'd prefer not to be—so the 40%-80% rule you heard is a good guideline. If you do charge it to 100%, don't leave it plugged in. This is something most of us do, but it's another thing that will degrade your battery's health.
Fully discharge it once a month.
This may seem contradictory, but hear us out. While lithium-ion batteries shouldn't be discharged regularly, most modern batteries are what's known as "smart batteries". This feature can get miscalibrated after a lot of shallow discharges. So, manufacturers recommend fully discharging your battery once a month to make sure this stays accurate.

Is this true?
you can be as neurotic as you like over this, but it really d doesn't make a lot of difference, just enjoy your phone.

The only big no no is to constantly discharge to below 5% and recharge . That according to the experts leads to a much shorter battery life .
Yes leaving on charge is a waste .
Wiping Battery stats does not improve battery life .
But all this is an old story posted time and again and bring nothing new .

It may be a waste but is it detrimental to the battery? I always plug my phone in when I go to bed and take it off the charger when I get up in the morning.

there is a built in feature that stops charging once battery level reaches 100%. so there will be no harm to your battery. I have doing the same since gs1
My old Nokia 3510 needed a battery replacement after 4-5 years since it only held 3 days worth of charge instead of the usual 7-8.
I constantly let it discharge from 100% (overnight charging) to empty, the replacement battery cost me 5 bucks.
My Galaxy S1's battery has, after 2 years, no observable loss in capacity with overnight charging to 100% and dropping to 10-15% over 1-2 days.
A replacement battery would cost roughly 15 bucks.
I could go on the same about my Laptop, Netbook, Tablet and other devices with rechargeable Li-Ion batteries.
The point is; don't try to forcefully extend your battery life, enjoy your phone. Most people replace the phone every 1-2 years and the batteries are designed to live that long with high usage and deep-discharging. If yours should not or you plan to keep the phone longer, a replacement battery is cheap.

All Lithium batteries have it (and need it) since there is a risk of damage, fire or even explosion when it is overcharged. That's why not the phone but the battery itself has the corresponding controller. Since the controller cannot measure the exact capacity of the battery (only an estimate), it is recomended to deep-discharge and fully charge (charge-cycle) the battery once in a while to reset the controller's counter.
Battery replacement is cheap and easy as abc. That's the benefit of having removable battery. Just enjoy your phone.

So why do Sammy stop charging at 99%

Still no one answered my question... :silly:
Is the small 40%-80% charges better for the long-term battery life?
