I know, maybe stupid q., but i dont know if I should just do cycles by completle discharge battery until the phone shut down and then charge...
And charge completely to 100% without interuption or there can be some??
And isnt it bad for lithium battery to completely suck it??
How many cysles??
Should I do some calibration on 100%???
Etc.
Thanks...
PS. It is said in kernel discusions (Saiyh kernel) that it have several cycles for battery to be with better life, or something..

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.

So if I'm reading this right...the reported battery % is actually higher than what we're shown....because it has some kind of "reserve" for when its almost completely dead? Or no.

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.

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.

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.

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.

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.
Click to expand...
Click to collapse
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.
Sent from my PG86100 using Tapatalk 2
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?

Ok, good to know I'm not the only one! Lol.

Yeah. Same here. I believe it is a driver issue since the battery is not OEM.

yap, and the Anker battery is way better than the stock one.
I agree! Once it levels out somewhere around 80%ish, the battery life is amazing! A great investment indeed!

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.

Thanks for the explanation!! Kernel mods?? Um, I'll pass... Lol. I can definitely live with it! I'm getting 14+ hrs with moderate-heavy use!

Could it be the voltage?
I know that the stock amaze battery is a higher voltage than a normal lithium ion (normal is 4.2v, the stock amaze battery is the newish 4.3v lithium ions)
I did a quick search and found something similar with the sensation..
Someone in said thread even mentions voltage

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 have done that - it is the instructions that came with the batteries.
Sorry, that was directed at the op, and fwiw conditioning (as per the Anker instructions) is separate from calibration.

try using the battery calibration app. that always resolves battery issues when flashing new roms (at least for me it does)

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

I have heard that don't let Lithium battery drop at 10-20%, and charge it frequently if I get a chance to keep the battery healthy

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.
