Personally, I dont use anything extra and my phone gets GREAT battery life

Why would you use those programs I'm sure they kill battery life faster I have lots of sync'd accounts on my phone and keep it on high performance and I get 16+ hours of battery with phone games and more if I turn on my custom battery setting from the stock battery manager I have gotten almost 2 days of life. You need to reevaluate bro battery on this phone is sick I even have an extra battery and have never had to use it.

I used my phone moderately with some email usage, calls and a few games and i got about 13 hours of battery life and had about 6% battery juice left to spare. How are you getting som much battery life? Did you do anything with the Sprint Bloatware? Did you uninstall some apps or freeze the. P
Thanks in advance....
I use Y5 to auto enable/disable my WiFi connections. Keeps the phone on Wifi as much as possible and I don't have to mess with it.
Juice defender does that. Before I had wifi constantly on, gps, 4g and battery wasnt what id expect. I mean ive never had it die on me yet but close. No frills controls clock speed depending on how much I need. Since ive installed juice and no frills battery is way better.

depends on what im doing. If i plan to be using my phone in and out of my pocket alot, ill have juice defender turned on.
if i know im going to be talking alot that day, texting and not much need for internet, then ill just leave my 3g widget off for mobile network.
other then that, the phone has great battery life.
I must say, on my evo i got super annal about having full charge and wanting to keep charging it all the time. I swear id get an uneasy feeling in my stomach if it went below 50%. when i first got this phone and had the 10% marks instead of the 1% marks, my brain about blew up and i didnt know what to do! lol
but now ive began to like the 10% marks bc im not as annal about wanting to plug my phone in bc now i dont see the amount it dropped in the last few minutes.
in all.. i guess this phone was made for me, or like the windows 7 people "my name is logan, and i invented the photon"

I'm in the same boat as you. I've been using/trying juice defender and have it set on balanced. It says I save about 1.5% every day. I have to email accounts syncing, text about 50 a day and use about 10min of internet and I was down to 40% in 9hrs. This was with out make a phone call today. Juice defender doesn't seem to really help anything.
I use an app called Brightness Profiles from the Market. Used it on my old HTC Hero as well. Its a precise, quick and easy way to manually control the screen brightness. Most of the time indoors I have brightness set to 0 or 10% which is plenty bright for me and saves a ton of battery.

I was just noticing the brightness of the Photon's screen last night just before fallin asleep. My evo on 0% was DARK in a dark room, but at 100% in the sun you couldnt see. The photon seems to be in a different ballpark. 0% it still looks super bright and 100% is WOW a light in the sky.
when i look at when my battery is being drained the most, its def when that screen is on. i think a rom or theme with black/night colors will def help out because the bright colors of white are probably not any aid to the battery conservation.
yesterday i kept juice defender off all day. got 14 hours and 37 minutes till it hit the 30% mark and the icon changed colors. i had about 2 hours of web surfing, about 3 hours of total call time, and about 150 texts and almost a dozen MMS. (buddy just picked up a new chocolate lab puppy )
so im impressed. i def agree, looks like juice defender is not a good fit for the phone yet. the toggling radios on and off probably kills alot of power.
I have to agree, Juice Defender doesn't seem to be doing much. I get around 1.47-1.6 with JuiceDefender.
Other than that I run SetCPU with my profiles set up.
I some times when I am at work use a custom battery setting which pots screen at lowest and disables data during peak hours after 45 minutes of inactivity. It works great especially when I am at work and have some longer breaks between checking my phone. I also work and live right next to a sprint tower so I always have great coverage.

I still need to use juice defender ultimate for about a week to get a good history from it but right now im at almost 19hrs to full battery drain.
Sent from my MB855 using XDA App
Juice Defender, 36-38 hours before switching to 2nd battery.
Set to sync all every 1 hour. Twitter, corporate mail, 2 gmails, corp calender, contacts, etc.
The main difference is I set the screen to off in Juice Defender under toggles, not to trigger the data on just because I pulled the phone out and turned the screen on, doesn't mean I want to get on the web. I can easily pull up local info w/o that. In the morning, and in the evening, wifi is on for 30 mins or less each time to download podcasts on doggcatcher.
Lots of texts, calls , 150+ emails delivered a day, plenty of app usage, plenty of google.com searches. Maybe 1-2 app updates a day. Audio and video usage around 3-4 hrs daily.
I can go to work at 7:20 in the morning, get off at 5-5:30, and my batt stats are 75% left. Am usually sitting at 60-65% left by that 12th hour.
Can you let me know what your exact juice defender settings are? I have ultimate juice defender and am lucky to get 8 hrs per charge,

That's because you actually use your phone. These people who claim 30+ hrs of battery just have it sitting around most of the day not doing anything on it...very minimal use. For people who bought a smart phone to actually use the "smart" features of it, they will see anywhere between 8 -15, of good use. Keep in mind these phone are only rated for 7-8 hrs of continuous use, max. I say, use it how you want, don't cripple your phone with auto killers and apps that turn your data off, that's the whole point of your smart phone is to consume and transmit data. Use it how its meant to be used and enjoy it!

Well said. My advice is just find a cheep aftermarket battery and keep it handy just in case.

Why buy juice defender when the photon has these features built in. Just go to battery mode and chose "Maximum battery saver". After 15 mins it will turn off all syncing activity. Also when you're not using your phone turn off syncing completely it really helps your phone last 10-15 hours easily. I'm a very heavy user so while I'm at work I just turn off sync! Plus I also received a replacement battery from Motorola because my original battery had problems. I couldn't get more than 8 hours with the first battery (maybe defective) so they sent new one.
I agree with the post on people claiming 20-30 hrs.. they flat out dont google and drool over theyre screen all day.. like most others do though.. that is why batt life is always always will be a huge issue!
Nothing ever really will help kernels.. roms ...juice def..undervolting.. it really
dont make the huge diff people expect..
Samsung has about the best batt life youll find on an android device.. with the exception of a few devices.. dual core affects alot more than a noticeable benifit!
Only real option to date is a EXTENDED BATTERY!

I've not been able to drain this thing since I got it a week and a half ago. I have to say that I like to charge things over night. I've not been able to get the Photon below 40% before I go to bed each night.
I hear that you need to drain it full at least once but my habit of charging things overnight is getting in the way. Should I just let it go overnight one night?
I was under the impression that completely draining Lithium Ion batteries causes more harm than good.
"The smaller the depth of discharge, the longer the battery will last. 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."

Also, i'm sitting at 46% after 15 hours of normal (for me) use. not to shabby. I should mention i'm running Juice Defender and build 4.5.1A-1_SUN-198_5 from the dev. forums and i'm connected to WiFi 90% of the time.
going to try tomorrow without Juice Defender and see how it does. After that i'm going to disable SPB Shell and see if that makes a difference.
Thank you sir. I don't want to root my phone so don't run Juice Defender but I do use the Data Saver in stock a lot. I usually just listen to a lot of music and look for new stuff on FB, check XDA forums blah blah blah, yada yada yada...
I'll not feel paranoid about charging my phone now lol.
Now with my tablet (Acer Iconia A500) I did root and load a bunch of different stuff. This is my first cell phone though and I didn't want to mess with something that I have to pay a monthly charge for. I know I could but it's my first cell phone lol.
How much are you guys using it? For me, I use about 30min talking, 1 hr heavy wifi use, 1 hr light wifi use (reading), 30 minutes playing with settings, and the rest of the day idle...that gets me to about 30%.
I actually thought that is kind of weak. Maybe my battery isn't as healthy as yours? I've only had it for 5 days. I charge it every night.
I use it for about 7 to 8 hours of music, FB updates/posting, checking XDA, about 10 minutes of calls and so far some Netflix watching just to show off the phone to my peeps. Oh and some picture taking.
I am the same way I hate to discharge it completely and its been very hard. I've went a day and a half without charging before it went under 10%. I will say that I am on Wifi 90% of the time as I have wifi at work and at home other than that its on performance mode so no true bells and whistles. I'm thoroughly impressed coming from the Evo.

Average day for me is about 30 to 45 minutes of phone calls, 80 to 100 texts, few conversations on google talk, 30 or so emails on three accounts and i have trillian running connected to two accounts.
Connected to WiFi most of the time, bluetooth is turned on (not connected most the time) and brightness set to Auto.
I really dont see how this phone is a monster when it comes to battery life, I've actually been getting the exact opposite. I just fully charged my phone and after running for 2hrs and 7mins its down 78%.... This phone has yet to last me for the whole day. What am i doing wrong? I dont have tons of widgets and the only app that im running that might pose a problem is Go Launcher

Is that your screen on time? If that is then I would say that is impressive already. When I had the epic on stock if I use it for 2ish hours screen on time. I would need a recharge. (Got a lot better after using custom rom. Around 4 hrs screen on time before recharge)

For the past couple of weeks I've been swapping batteries with an external charger one to two times during the course of a day (plus the overnight charge)... Looks like it's time to do some housekeeping...
Edit: used to have battery life like everyone else in this thread though! While at the climbing gym last night I noticed that the thing felt like it was about to catch fire against my thigh - it had burned through about 60 percent of a freshly charged battery in about two hours. I have a nagging suspicion that I neglected to uninstall something (or a few things), and now something non-existent is constantly being polled for as a service after I launch some app for the first time...
when i got my phone it did great on a full day charge, but now with it just sitting at the office its at 70% by 11am i take it off the charger 7-8am .. it started to "weaken" after i downloaded a ton of apps i leave wifi on and 4g off but it also depends on your signal strenght at home it will kill the phone halfway thru the day because i have one bar
I ,am on it a lot, between GPS and general usage, ,but this still seems like too fast to drain compared to what others here have said. I had this problem with my Atrix too, maybe i am just destined for bad luck with battery life

Apps like that only increase standby battery life. Everything else is very minimal.
And I'm not happy with the battery life either. My phone is plugged in right now and the battery is actually going down as I use it.

If it's notbthe stock charger you areblikely not using a rapid charger.
Sent from my SGH-I717R
I pull mine off the charger at 7:00 and at 3pm or so it's down to 85%, I'll put it on the charger at work until I leave around 5-6pm (mainly because I'm used to having to do this on my previous phone) and at night if I'm not using it constantly it's around 70-75% when I plug it in at bed time.
I suspect anyone getting that bad of battery life must be using it constantly, ie: Playing games, browsing, trolling facebook, etc.. Even in the "new toy" stage I'm getting great battery life.
FYI I don't have LTE, but do generally have good 4G.
You honestly can't use any phone on GPS without external power and expect that you're not going to discharge quickly. Assuming that you are running a car charger during GPS and just didn't say so, search the i-717 threads, since the topic has been well vetted on what chargers are more effective,etc. There are definite differences.

The fact that there are people out there that get really good battery life means the problem is you and not the phone. If you refresh facebook every minute of course your battery life will be crappy. apps like juicedefender are just marketing crap. as long as there are no running apps in the background that eat your battery, you do not need any juicedefender or tasker. also setting screen-off behavior to conservative on set cpu helps improve battery life.
When I first got my i717 and was using it on the stock rom I had pretty terrible battery life. I take it off the charger at 5:00am and had decent battery life (around 5 to 7 hours without GPS) but I use my phone a lot for internet/email. I think your battery life is completely normal given your usage.
Most people get about 5hrs screen on time. Total on battery ranges up to about 24hrs, but only if the screen is off at least 19 of them.

I had GPS running on my phone for 4 hours today, had blue tooth on half the time without knowing it, sending text messages, making two 5 min phone calls, checking maps, checking FML and reading a book for about an hour and drained down to about 70% and I have the brightness set at auto. I would exchange it for a new battery.
On average with several texts per hour, several 5-10 min phone calls, taking a few pics and uploading them to picasa, checking facebook, updating status and checking emails I can pull off the charger at 630am and still have 50% battery (at least) by 630pm.
I do have the juicedefender (which isn't crap, it turns off signal after so long so you aren't trolling for signals when you aren't on the phone).

I had a ss of my buddies yesterday, but can't restore mms lol. There are plenty of other ss in the note section. He was at 22+ hrs with about 4:30 of screen on and some % remaining. I have to charge around 7-9 everynight at 4-4:30 hrs screen on, but my use is pretty heavy. I sync 4 gmail accounts, a separate GV, 3 calendars, and several apps.
If yours is much worse than that, you likely have a few troublesome apps or are playing games. First, after a full charge, reset cpuspy timers, lock it, and set it down for a few hours (I know, impossible). Then check to see that your CPU has been in deep sleep about 95% of the time. If not, use better battery stats to see what has been request wakelocks. Not only the most total time, but the total number. Any app that looks outrageous, freeze it or uninstall it. For system processes that look troublesome, Google. You can often find simple tricks online that will tell you what's causing them to go crazy. Beyond that, turn off syncing of anything that isn't needed or doesn't matter (like Facebook), and uninstall stuff you never use.
Another slight help is the brightness widget (don't use the actual widget, just put the app on your homescreen, it works the same) or dimmer in market as they can both set the brightness to a value of 10 (Samsung lowest stock is 20), and even if you can't tell the difference, it helps. Jkay settings in saurom can set the auto brightness profile slightly darker than stock. Umm, and the obvious, use less Widgets, longer sync intervals, processor scaling and speed profiles, and buy a couple rapid chargers, wall and auto.
A couple things to note after seeing a few of these posts...
BT can be on, but without it searching, connected, or listening it's not active.
GPS isn't active unless its in use aand you see the icon in the notification bar. That being said, fb, websites, and many other apps that request location will activate it.

YOU MUST CALIBERATE THE BATTERY!! I have no issues I use my phone heavy all day and get 15 hours and I still have 20% left. All you have to do is
1) Charge you phone until it says "charged"
2)Leave phone plugged in and power off and let it charge until the battery meter literally says "100" (screen will sleep so you can check with volume rocker to light screen)
3) power on phone and let boot and than power off and wait till you see 100% again
4) now keep doin this and you will notice it will start displaying "100%" faster and faster usually takes 6-7 times cycling like this
5) After you do this download Battery Caliberation (root required) app from market and hit the caliberate button and boom your good to go
I do this on every android phone I own when I flash a new rom or purchase a fresh one. Everyone should do this everytime you flash a new rom and I can CONFIRM significant battery longevity on all my android phones I have done this with
You only have to do it once so just get it out the way and you'll get through a whole dayand have some juice to play with.

Just to be clear here, Tasker has nothing to do with battery life. It doesn't hurt it, nor "help" it. However, you certainly could write tasks/contexts that would decrease battery life, and there are a few scripts out there which do silly stuff like autokilling, etc... But if we're talking "battery savings", Tasker and JD do not go in the same category.
IMO JD is only useful if you're frequently in an area with no signal, like you work in a basement or deep inside of a solidly constructed building. Since you mentioned Tasker, in this context it does help me a bit on battery because my wifi turns off when I leave the house, but that's also something JD can help with. If you don't have a wifi connection it'll turn off wifi (and I believe turn it back on periodically to see if there's one available?) I don't use JD, so can't speak too much for it.

Hour? Hour and a half? I'm working during that period. I usually hit news sites and G+ when I'm first at my desk in the morning, so that's 30 minutes or so off and on looking at it, then perhaps an hour over the rest of the day, sometimes more at lunch.
I'll look closer today and post back.

This is my 4th note. The 3 I had previously the battery lasted a long time. I kept the same battery from the first one in all three exchanges. I took the new battery for this fourth one. Could this battery be a bad one or should I return the phone again for a 5th time. I don't wanna take a chance getting a phone with the problems I had on the other 3.
Just looking for some opinions

Good Lord, 3 exchanges! Wow... try running the battery all the way dead where the phone shuts itself down, keep it on the charger and charge it overnight (or in the realm of 8 hours) while leaving it off and see if that makes a difference. I ran my batt that way once and I'm getting 18 or so hours per charge (depending on how much I play with it).

I only get about 3 hours of screen time myself. Seems normal for this phone. The huge screen eat up battery fast. Plus if your using LTE, so good bye to your battery.
I don't think you have a bad phone, That's just how it is in my opinion...
so whats your total at the end.. like say.. 5%..?
If you're getting about 3hrs screen time, I'd say you'd be on par with what I'm getting. Some days I can eek out close to 5 hours screen time, usually on the weekends when im at home and on WiFi.

Considering the size of the screen I am getting decent battery life, sounds like what your experiencing is normal :/ but going through 3 phones must be very frustrating.

Auto Brightness?
I don't know why you guys are getting such horrible times. With regular use I'm getting an average of 8-10 hrs screen time, depending on what I'm doing. I'm running Saurom RCVI, with Da_g OC Kernel, and tweaked a few of the JKay settings. I recommend charging to 100%, wiping batter stats, and doing a power cycle on it. That's what I did after installing above Rom/Kernel, and battery went from from 4-5hrs to at a minimum 7hrs.

I would like to see a screen shot of that
Fighting battery problems here as well. I'd assume it was normal for this phone, except when I see people posting great times.
1 week old phone. Switched to Saurom yesterday to see if it's any better. Screen regularly at 5%. Usually on Wifi most of the day (and I'm not in an LTE market yet). I set all my synchs (rss, weather) to 4 hours. Others (Twitter) are manual. Only Exchange Email is push.
Using Cpusy & BetterBatteryStats to try to see what's going on. Could be a bad battery - could be that the number I'm seeing is wrong.
Anyway, I'm getting about a 7% drain an hour *with the phone off* ! I'm even rebooting as needed to make sure it's in deep sleep & not 384 (which is very, very annoying). Unplugging the phone @ 7am means a dead battery by 3pm. And if I'm using the phone, it's more like 12-15% an hour (min screen, reading a book). Been charging in the car and at work - whenever I can for now.
Going to try to run some tests on the new rom. Leave phone off for 30-60 minutes & track % loss. Then, maybe put it in airplane mode & try again.
Some weird ones I see to often - Adfree, Maps, Alarm Manager (which I understand can come from almost any of my apps). Oh - tried Juice Defender, no help there either (didn't make any difference at all)
Finally, in the car with Waze (gps), a Podcast Playing, and the screen cranked up for visibility - the car dock/charger keeps the phone about even. On my HD2, a drive to work would charge up like 20-30% of my phone.
Really, really hope I don't need to carry a 2nd battery for days when I can't keep the phone charging.

How often do you get exchange emails? I stopped using push exchange email as it was a huge drain on the battery with the volume of emails I get...
With this phone the screen draws some serious juice, so if your using you phone in the car with the screen on its using about 950mah of juice, so your car charger will likely only keep this phone from losing power, it may not gain any juice, and it may even loose juice depending on charger power and what the phone is doing currently.
This is also why most of us are seeing about 3 hours of screen on time, as while the screen is on its using probably 700-800mah of power. divide that by the 2500mah battery and you can see why...
You can try other programs to try and help with things like background data, undervolting, etc, but that's all going to have a small effect as the "problem" is the screen, its eats up most of your juice. If you want to save battery you need to go after the big thing, the screen, not the little things. However short of reducing the brightness there's not a ton you can do about the screen. It is a big screen, and it needs big power to drive it.

I get about 5 an hour during the day. Will try setting it to once an hour in my testing instead of push.

I *think* (need to double check) that the charger is putting out 1A. Where did you get the 950m number from? Is there an appx. chart for different levels of screen brightness (how about 50% for example when in the car? oh - and how much lower is the 5% I use indoors?)
Agree, the #1 thing is the screen itself, which is why I get very confused when I have the large drain with the screen off.
I'll also have to try a test today where I turn on my podcast, but leave Waze off - and turn the screen off while it's charging in the car.

950mah is an educated guess. If you have root you can run this in a terminal to see how much power you car charger is giving the phone... (su first)
cat /sys/class/power_supply/battery/batt_current_adc
I usually get about 9100 for a result, which is 910.0 mah. and my phone will charge barely if I dont have gps going (screen on). if screen is on and gps is on the phone will slowly discharge, so that puts the phone power usage at about 900mah with screen on, so maybe 950 was too high of a guess. So when the phone screen is on, your using a ton of juice for such a small battery.
If I use just a podcast app and the screen is off the phone will charge much faster while in the car. If I have google maps running, it stays almost even...
You could even calculate your usage. She how many minutes your were driving with the screen off and the phone charging and note the amount of battery% gained in those minutes. You'd see a huge difference in charging times with the screen off. In my 50 minute commute to work, I gain about 20% battery charging with the screen off... With the screen on, I see almost nothing.
Seems like some days are better than others.

I've heard several different opinions on this. Condition or not to Condition the battery.
Do we need to condition this thing?
How are you doing it?
What kind of results are you getting?
Thanks in advance.

Li-ion
The battery is lithium Ion so you really shouldn't have to from my understanding.
People do even tho is not necessary, for some reason I don't but after a few day battery has gotten better

I mentioned this earlier -- I know it's a li ion that shouldn't need conditioning but when I first got mine my battery life was absolutely horrible. I went through two full discharge/recharge cycles and it seems to be much better now.
Currently 11 hours on battery, 50 minutes screen on, played a couple of games, downloaded a couple of apps, 15 minutes of voice calls, and battery is at 80%.
The way it was when I first got it, I'd probably be at 40 or 50% right now, if not even lower.
I'm also running juice defender and have stopped using the gmail app because you can't set the sync interval on it. Instead I've been using the built in email app and have it set to sync every 30 minutes. Not sure if any of this is doing anything but my battery life is definitely better than when I first got the phone. At first it was so bad that I came very close to just returning the phone.

That's true for me as well now that you mentioned it. First day, I got about 4 1/2 hours with it before i was down to 10%. I was shocked! Each day it has gotten a little better. Over the last 36 hours it has last a full days before a charge. It doesn't really make much sense to me that they are li-ion which shouldn't need conditioned but it seems that we do need to do this. A friend suggested I condition it when I got it and before I started heavily using it, I guess he was right.
Li-ion batteries don't need conditioned. Any signs of conditioning you see may be some sort of conditioning/learning of the OS.

See this kinda stuff freaks me out. I had one decent charge so far, had the phone a week, have been doing full discharge/charge the whole time. Sitting at 38% right now on 16 hours, about half of that was asleep with power save on (its been dropping 20-30% overnight) and only 48 minutes screen time. I dunno how long it should take to improve but it seems like its not taking this long for anyone else.

This is a very informative site. I've quoted it's recommendations concerning the circuit in the battery that needs calibration before......

How long do you usually sleep for???
Seriously though, 20 - 30% overnight sounds like a lot. I tested mine and it dropped about 8% in roughly 7 hours of zero use while I was sleeping. I think even that is a little excessive but I can live with it.
Have you tried running something like Juice Defender? It seems to have made a difference with mine. When I got my S3 last week it was about the same as yours. I did a couple of complete discharge/charge cycles, installed juice defender, and have been going into the task manager and app manager and turning off all the crap that doesn't turn off automatically. It has made a difference.
Oh, and I also did the APN trick to disable LTE. Not sure if that has made any difference but with everything combined the battery seems to be doing a lot better than it was at first.
Don't "they" say that you should not use task managers as they don't work well with the phones? I'm no expert here, so don't quote me, but my understanding is that the One S and Siii owe a lot of their excellent battery lives to their own internal task managing.
Correct me if I'm wrong here.

The internal task managing is the reason you shouldn't use 3rd part task managers. That's the whole point. Android has done this since 2.0
Having said that, there's nothing inherently wrong with killing a task that is misbehaving... most things that say not to use task managers really mean to not (a) turn on auto task-killing, or (b) kill tasks across the board, albeit manually, under the false impression that freeing up RAM is a good thing.
When you guys say full discharge do you mean draining the battery till it shuts off or going down to 10%, I was under the impression that fully discharging would harm the battery.

I discharged it till zero. Then I turned the phone on and let it shut off again. I did this until the phone wouldn't even try to turn on any more.

Doing this enough times has the potential to damage your battery. Leaving it at 2% - 5% will not make a difference in the "calibration" compared to completely killing the battery.
Killing the battery may work for you, but I want others to be aware of the potential of damaging the battery.
Just my 2cents for the day.
Here. Is a link to battery charging for Li-ion. I have another site that is great in explaining these things. I have a couple of R/C trucks and this info is great to know and have. The same applies. To our phones charge rates. I would hope that when a dev makes up or mods a kernel that they have a basic knowledge of charge rates and the rest of the equations. Foe our batteries this is literally. Life and death. It could also cause a phone to burst into flames. Especially. If we use after market batteries that have poor protection circuitry in them.
I will find the other link later and post it up here to give a possible better understanding of these things. But, try not to rely on me as I tend to forget things a lot. Car accidents will do that to you when you crush your skull. Any way, GIYF.

You basically only need to do the "calibration" once. And the phone has limits set that will neither undercharge nor overcharge them.
edit I think heat is your batteries worst enemy.

This is the WORST thing you can do to a Li-Ion battery. I mean literally you can lose 10% of its life from doing this or even cause the battery to stop charging at all.
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the battery’s protection circuit puts the battery into a sleep mode. This renders the pack unserviceable and a recharge with most chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before a long storage period.

Seriously everyone should spend a couple hours on that site at some point. Half the information will probably be way over your head (or at least it was mine) but there's enough good information that even half of it is definitely worth learning.
Here is the other site that I was talking about. Though it is for R/C battery packs it should still grant a measure of understanding to the workings of these batteries.

Take into account though. These batteries have circuitry. Built into them to prevent you from truly discharging. It all the way. That doesn't mean that it can not discharge all the way. Things like humidity can play its roll in taking a Li-ion or Lipo battery past the kill zone point. If you know that you will not be using the battery for a good period of time or it is strictly an in case of an emergency battery. Place it into a plastic bag and suck out all of the air that you can and seal it. A zip lock bag works best. Place it in the refrigerator or freezer. There is very little moisture. In there. And what ever moisture makes its way in when you open the fridge. Or freezer will not have time to get into the zip lock bag. The lack of moisture slows the discharge process down especially in the summer. Also the chilling of the battery's chemical. Compounds slows the molecular interactions down. Its a helpful two fold process.
