The batteries in our phones (and most newer electronics) are Lithium-Ion (and in some newer phones Lithium-Polymer). these batteries have no 'memory'. in fact discharging them all the way is very bad for them, and can actually cause the battery to rupture if its done too extreme (you would have to short the terminals for this to happen)
The reality of this is that the less you let your battery discharge, the longer it will last. Every time you let it drain all the way (or almost all the way) you are harming it and reducing its lifetime.
The best way to take care of your phone's battery is to try to keep it between 50% and 80% full. Even keeping the battery fully charged for very long periods of time can be just as bad as discharging it fully.

The "cycles" which supposedly prolong our battery life are not true. This used to be the case, but like TopDroid said, with lithium batteries they do nothing.
Its like how on older versions of Android, task killers were useful, but newer versions don't need them and is actually bad. With batteries, the technology has progressed from that time.

But isn't flattening Lithium Ion batteries bad for them? If you search the internet it often says not to over discharge as well as under charging them also increasing their life span. The older NiMh and NiCd batteries benefited from full discharge and recharge.

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.
Aww crap I discharged it to zero last night. I thought out make sense cause back when I used the nexus one, there was this method of conditioning battery by discharging the battery. Ah well thanks guys

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.

This was common on my droid x for so long while flashing but is it a good form of practice on the Rezound? The reason I am asking is I flashed Bamfs Cubed rom and my charging led goes from orange to green at 98%, never making it to 100. Would it be wise to go ahead and wipe battery stats and see if it fixes it? I presume there would be no harm to the system or battery in doing this.

Don't agree. Just like I don't agree with people saying task killers are bad. I guess with the way I use my phone I get different results. I have always noticed better battery life wiping battery stats. Now it could be that the OS will fix battery stats itself over time, but when you ate bouncing around a different rom every two days then the OS doesn't really get a better feel for the battery.
Plus...I came from the evo 4G where we uses trickle charge kernels and I want those back. Never had better battery life than when I had those. Was doing 35+ hours a charge on the stock battery.

Haven't bothered since I never could get the thunderbolt devs to try it. There was "reported" cases with no proof that it caused some batteries to go bad. Even then they were cheap Chinese batteries that 2 people total I think it was claimed went bad.
It was always nice to pull your phone off the charger in the morning at 100% instead of it showing 100% and you pulling it off the charger to say 92%.

Well there is the fact that Li-Ion batteries can not be trickle charged after reaching full charge...
Well they can, but it will hurt the battery. And that isn't me talking from a few bad battery posts... but from knowing how Li-ion batteries work and charge... and reading engineering papers about Li-Ion batteries.
Luckily trickle charging is slow and most people only leave the battery on the charger over night at most. Plus they charge while the device is running and using power. Should someone leave the charger going for 24 hours, with the device off, we would probably be hearing about a fire.
What is probably happening with these trickle charge kernels is:
The phone is going to use some power at all times, the trickle charge is probably just enough to keep the phone running and preventing the battery from draining slowly.
This works because there are two ways to handle full charge status while the charger is still connected.
1) When the battery reaches full charge, the battery is isolated from the device preventing the device from draining the battery. The device then runs solely off the power coming in from the charger. (this method would not benefit from trickle charging, and forcing the battery to continue charging will at best slowly hurt the battery over time, and at worst cause a fire/explosion)
2) When the battery reaches full charge, the charger is isolated from the device. The device runs off the battery until the charge drops to a certain level (usually around 90% or so) before charging starts again.
The second way is how the Rezound does it, and most other devices as well.
The first way requires the ability to switch instantly to the battery from external power without any drop in voltage. This is difficult to do, as a drop in voltage could cause the device to crash/freeze, so many devices do not use this method.

Well if the device was off then the kernel wouldn't be running and trickle charging the battery but when turned on and the battery fully charged they would very slowly charge the battery as it dies. So there should be no risk of the battery catching fire. And anyway, the way the evo trickle charges worked is they would charge your battery to a certain voltage. Once it hit that voltage it would stop charging until it dropped. So it wouldn't be hard to protect the battery.
Did this for 6 months on the evo with no issues.

One battery will be recharged with the S2. The other battery with an Anker wall charger. That's just a plan right now
I would like to know something concerning the best recharging strategy & battery "calibration" if you are using more than one battery:
If you are using only one battery it's quite simple how to calibrate the system.
But if you are using 2 batteries alternating then you can run into trouble, because the system is "calibrated" to the first battery.
That means if you are using battery1 until 0%. The system knows battery empty. I you are putting the 2nd - already recharged with a external wall charger - into the S2 then I wouldthink that the system is confused, because you didn't recharged it internal.
I want to use 2 batteries for travelling where I need a lot of juice for GPS.
So I would use the first battery until 0% and then change to the 2nd which is already recharged and then draining it until 0% and then again recharging.
The other strategy would be drain the first battery until 0%, then using the 2nd until the evening and then recharging both during the night. But I think this strategy will confuse the system.
Hope you understand the problem and I hope someone knows the best solution!

You don't need to calibrate the battery on the s2. The device should fix the percentage by itself. I would not recommend that you drain the battery fully to 0% as i have heard that it could damage the battery and use multiple cycles for the one you drain it. If you're running SiyahKernel you can try to reset the fuel chip in extweaks. Some say that it's a placebo but I seem to think that it works.
Hope that helps you out

The batteries should be charged just right if you use the wall charger, however sometimes when you charge in the phone, it might stop at 96% or somewhere around there, sometimes I off the phone and charge, gets it to 100%

Again, sorry to bring this thread back to life.. However I was wondering if anyone has had issues with using two batteries and having the "fuel gauge" chip fault on them. On my previous Galaxy S3 the chip that is dedicated to measuring battery stats, as found on many other phones, developed issues. This lead to the phone registering increases in battery percentage while off charger - basically the battery history graph at any given time had a 60% chance of going down and 40% of going up.
Could the use of two batteries caused the "fuel gauge" chip to malfunction?
Maybe temporarily. But charging it to full and/or resetting the fuel gauge running a kernel that supports same fixes that issue easily.

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.

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.

Is the small 40%-80% charges better for the long-term battery life?
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.

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)

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.
