Charge the battery, run it down to zero, charge to full, repeat for the first dozen ours so times, battery life has been improving in each cycle and I also recommend you do the same

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.

[Q] charging and battery damage
If I leave my touchpad on the touchstone charger for long periods and the touchpad is switched on will this damage the battery?
I know I have had laptops and always ran them of the mains and the battery has stopped holding a charge.
Cheers.
I assume that the touchpad has a charging circuit that stops it charging when the battery is full, but batteries will always fail after a while regardless. Lithium batteries are best charged often and not let run down too much in between.
Also, dson't let a lithium battery run down completely, you can significantly shorten its life doing that.

source? I thought lithium battery had no memory.
It's not a memory issue, running a lithium battery flat (deep discharging) has a physical effect on it where it will lose it's ability to recharge to as high a level as the previous charge. Each time this happens the battery loses more of it's ability to reach an effective voltage.
Don't take my word for it, do your own research, there's plenty of information out there it internet land.

The dev for Dr.battery's has a thread that states that leaving your Touchpad on the touchstone for long periods of time should not impact the battery. Due to it switching to powering the unit after its charged. Though he is doing some testing on that. Also his app should be updated soon for the Touchpad (available through preware). I am still going to contact HP to discuss this as well. I would hate to damage a non replaceable battery. Will update if I have any new info.

I have done my own research. That's why i don't think this is accurate.
If you have some proof please share.
Besides common aging, a Li-ion battery can also fail because of undercharge. This occurs if a Li-ion pack is stored in a discharged condition. Self-discharge gradually lowers the voltage of the already discharged battery and the protection circuit cuts off between 2.20 and 2.90V/cell.

http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Basically through normal use you can probably expect around 250-300 full charge cycles (partial charges only count as partial and add up with other partial charges to be a full cycle) in an average battery pack before it has degraded to 80% of it's original capacity. I don't see anything that point to full discharges being damaging. However storing it for longer periods of time fully discharged can affect life.
ambivalent-one I think the figure of 250-300 charge cycles you've pulled from that page refer to deep discharge cycle tests done by them, personally I'd be very unhappy with that kind of lifespan in a battery in regular usage. The same page you've posted http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries shows a chart of charge cycles versus depth of discharge.
Table 2: Cycle life and depth of discharge
A partial discharge reduces stress and prolongs battery life. Elevated temperature and high currents also affect cycle life.
Charges - Depth of Discharge
500 - 100% DoD
1500 - 50% DoD
2500 - 25% DoD
4700 - 10% DoD

As you can see a L-ion battery can be made to last nearly ten times longer by keeping the charge level up near max.
Quote from http://www.batterieswholesale.com/damaging_batteries.htm
The Li-Ion cell should never be allowed to drop below about 2.4V, or an internal chemical reaction will occur where one of the battery electrodes can oxidize (corrode) through a process which can not be reversed by recharging. If this occurs, battery capacity will be lost (and the cell may be completely destroyed)

Look at the "Safety requirements" section for a start.
Also Google "lithium batteries discharge" returns some useful links.
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.

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...

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.
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.

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.

When the first EVO came out this method was dine to train the phone more then the battery and I still use it.. drain till it turns off.. turn back on..keep doing this till it will not turn on..full charge it.. take off charger and put back on till led is green again. I've never burnt out a battery but I can't professional it helped battery life but as I said when EVO first came out battery life was horrid

The LG Fusic had a LiPo battery.
Yeah i bet some phones will have no charge after customs played with them for a while and did not turn them off and put them back in for us to get screwed. But you may have a update already apply as well to the phone.

If I recall correctly, only a sample from each batch was tested and that tested sample was not shipped out to customers.
Yup thats what I heard as well
What I read says this phone has a LiPo battery. They are being used more often in portable electronics than you think.

I heard LiPo as well.

simple solution.
keep the phone plugged in while you use it. duh.
charge at the wall and your office computer
...
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.

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