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.

ok my battery just fully died should I charge it on for 8 hours or charge it with the phone off off until green? which is the best method?
personally I think it's all bull****. Just charge the battery when you need charging. All this calibrating talk is bs.
The battery life on the 3D is significantly better than what the OG Evo was. Therefore I would say that just charging when you need to is probably your best bet. You don't need to Calibrate the battery because Lithium-Ion batteries do not have a memory which would dictate any sort of history.
I have done a lot of reading on www.BatteryUniversity.com and to my understanding with lithium ion you want to avoid a full discharge. With my 3D I have just been running the phone normally and letting the battery drop to around 40% and then fully charging and I have had great battery life.
If you are consumed by how to condition/charge the battery I would suggest reading the articles on Lithium-Ion on that site that I posted.
Hope this helps.

I laugh every time I see people saying what they do to charge their battery. Stand on one foot, rub your head and pat your stomach, charge for 8 hours, unplug for two minutes and charge again for an hour, do a barrel roll.
This is nonsense, Lithium-Ion batteries do not have a memory, they can not be trained in any way.
Also you do not have to worry about a full discharge, your phone/battery prevents this. I believe you only have to worry about this when using some serious stuff like RC items like planes, cars etc.

People don't so much train the battery as they train the phone. Like on the OG EVO, when you would do a batt stat wipe, you needed to fully let the battery die and then bring it to a full charge. This was so the phone knew where the battery really was at 0% and 100%.

how good is ur battery life charging that way u mentioned?
It doesn't take much research on these forums to figure out that Calibrating has nothing to do with the battery. Of course the battery has no memory, nor can you get magical extra capacity out of it.
When you calibrate you are increasing the upper and lower limit of "what the phone" thinks the battery capacity is. Which in turn makes the battery meter "on the phone" more accurate and allows the battery to be charged more completely.
I get an approx 30 mins of extra awake time since I calibrated using the procedures in the Evo 4G thread.

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.

Lithium Polymer batteries are not the same as Lithium Ion batteries.
Avoid draining them to the point the phone shuts off. If they get too low they die.
Never run them down on purpose.

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.

What is the proper way ? I've looked online and people say differently. People say let your battery drop to 15 percent or a little under then fully charge. Then others say let the battery completely run out until the battery dies then fully charge it, but I heard letting the battery completely is bad and not necessary. So what exactly do people when when they say fully discharge or battery manufactures when then say fully discharge a brand new battery then charge?

Down to atleast 3%. That's how I've done it for years. Every opinion differs though
I always charge my phone when I know I will need a full charge, I never really cared about the battery percentage too much, but I do agree that there is no real wrong way.
It's my understanding that in order to properly calibrate a battery you must completely drain it.
From what I've gathered the battery needs to know what a "full charge" is and the only way to get a full charge is to be completely empty.
So following instructions from threads back on the MT4G forums I calibrate my battery by:
1. Letting it completely die.
2. Turning it back on just to make sure it dies again. And I do this til it won't turn on again.
3. Then charging it, while off, til it has a green light.
4. Then I unplug it, turn it on, turn it off and plug it back in til green.
Whether this really really makes a difference or not...well I can't say for sure
but my battery lasts longer than my sister's Amaze.
Hope that helps.

same with me, I never bother with letting it drain fully, I did with my first phone, and a few months after I got it the battery was pooched, so from then on I never cared. plus with the cost of getting a replacement, or even aftermarket batteries like anker, not following procedure to drain then charge a battery is a no brainer for me.
But, if I did care, then I'd drain it fully, then charge it back up. the percentages on my phone aren't accurate anyway. Actually today I was playing blade master and I kept getting the battery warning, and it was pretty steady from 20 down to 5, then hung there for a while, maybe an extra 15-20 mins, then died. so percentages are approximate. a full drain and then full charge should do.
What the other guy listed in steps is correct, though I'll give you a heads up, the amaze battery is total ***** when it dies completely, so be prepared to have it plugged in alllllllll night for it to charge.
Just got my self a replacement, the battery ended up dying, took me four hours to move 8%, was about to go buy a replacement the next day, but I let it charge overnight, it's been remarkable since then.

Lol my bad bro, I was just too lazy to scroll up to look for your name.
So, if you would care about calibrating, do you let it die and fully charge every time you flash a ROM? Or just the very first time when it's new?
Seems every battery is different. I let mine die completely and then charge overnight, but had the green light after an hour and half. I let it stay on though overnight.
I personally didn't see a drastic difference.
A lot of folks day to wipe your battery stats as that helps. I have yet to try that.

Wiping battery stats doesn't help, IMO, for the number of times I've tested it on a few devices. My results so far just shows that wiping it just fools the device to stay full longer than it should but after the battery passes the 90% physically it starts making rapid drops until it stabilizes somewhere around 50%.

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?

Mine does it too. But it stabilizes around 80% and I can get a good 16hrs with moderate-high usage and about 3hrs screen time. I was reading somewhere that this is a common issue with Anker Batteries.

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.
