When I get my new toy tomorrow, I plan on using it! As per what I've read, gonna use it down to 10% or so...then give 'er a full-up charge. Kind of curious what everyone elses' plans are for their first time 'round?

Most likely this, but I may play around with the spare battery and throw the battery in the charger for 8hrs

Is that the general consensus on how to break in the battery? First move to an android phone and learning all I can.
I have always charged it up when i get it first then all the way down...but we all know how it is when we get a new phone....can't put it down! So...i play a bit first..
Confirmed tomorrow delivery!

I usually run it dead first then charge it to full. I don't think there is a wrong way to do it anymore. someone correct me if I am wrong and why.

Congrats to everyone *finally* getting their beastie! I can't wait for mine...nor can I wait to PLAY with it! I did some researching on ye ole battery issue...there are a lot of different theories...so I decided to go with the "drain it out of the box, then charge" because this fits in with my extreme need to PLAY! I read it may be a good way to go to "break in" the battery, if you're of that school of thought. Some people say they do not need "broken in". Some say they need fully charged first...yada yada yada and so on & so forth. I do think the newer batteries are different than those of yesteryear in that they don't have a memory, etc, and some of the old schoolers are still stuck with that thinking. Maybe. I dunno. I'm far from any expert. (I just wanna PLAY!!! lol)
Anyone try out that Ready2Go thing thru AT&T? Kinda neat. I did it. We'll see. I just did my contacts though. The rest is taking the fun away of customizing a new toy!

A Google dev came out and said on XDA a while back (the heck if I'm going to try to find the post) that battery stats have basically no effect on anything anymore. All the same, I "grew up" on cell phones by draining them to 0, then plugging them in until 30 minutes after they show a full charge, so I've just kept doing it that way.
It seems to me that companies wouldn't send out a battery without testing it... Which would involve charging/discharging it. So I don't think there's any need to treat a battery any differently when it's fresh out of the box than you would after the "break-in" methods people have posted in here.

this is probably why I do it too.
You should not be using the same method on Lithium-Ion batteries that you do on Ni-cad... cause they ain't nicad
Just do a little research. They don't require any break-in. Not only that but it's suggested you charge often and not fully discharge if you can avoid it.
Just plug the phone in when you get it and charge it up. If you want to use it feel free, plugged in or not.
Some common tips taken from Gizmodo and Blackberry's sites:
• Do not let it run out completely all the time. Full discharge puts a lot of strain on the battery
• Do not keep a Li-ion battery fully charged all the time, either. If you don't use your battery it might suffer from capacity loss
• Keep your battery in cooler temperatures. Hot hot heat is not good for it
• If you're gonna store your battery, leave 40%-50% charge in and store it in a cool place (i.e. fridge).
1. When you get a new Blackberry, charge it fully to 100%. There is no 120% or 130%, so once it hits 100%, it is fully charged. This normally takes about 2-4 hours for a new device. There is nothing wrong with “over-charging” the battery, however there is no real need to do so. Sometimes, new Li-ion batteries will come fully charged out of the box.
2. There is no “break-in” or “conditioning” required for the Li-ion batteries. They do not need the old “fully discharge – fully charge” routine for the initial three charges as was recommended on older battery technologies.
3. If you are a brand new BlackBerry user, keep in mind that you are likely using (or playing with) your BlackBerry much more the first few days than in normal routine use. If you think you are having quick battery discharge issues, give yourself a week or so until your daily BlackBerry usage levels off to a perceived normal amount. Don't freak out after the first one or two days if your battery depletes itself halfway through the day--You're probably using the device at a higher than normal use.

This is exactly right. Lithium Ion batteries benefit from smaller and quicker charge/discharge cycles. Actually draining a Li-ion battery to 0% and letting the phone die can decrease the total battery capacity and causes unnecessary damage to the battery. You should never do a "deep-discharge" and full recharge on a Li-ion battery.
Just pull it out of the box and use it, charge it before it hits 0%, and you'll be alright.
Heres another trick
I have done this more than a few times. Does it make a difference? I cannot say with anything more than anecdotal evidence, but I have had noticeable success and the logic makes a certain degree of sense.
Running the battery fully down often is claimed to be detrimental, and I have no reason to doubt that. Doing so once in say, 25 cycles is probably not a bad idea, although it does not do much of anything to capacity. What it does is help calibrate the battery meter. Than I add the following technique to increase the discharge time (run time) of the device:
At whatever point you finally let the battery fully discharge, do this as well:
If you have power saving feature, turn it off to get the job done. When it actually shuts down from being fully discharged, plug in and charge fully with the phone OFF. When the battery reached 100% fully charged take out the plug, wait a minute, and put it back on the charger. It will charge for 5-10 minutes more. NOW remove the plug, boot the phone, and put the plug bag in again (more charging ensues) and repeat one additional time. THIS technique seems to "Stuff" more electrons into the phone (see how scientific my explanation is? Whether I am helping, hurting or having no effect on the batteries longevity i can't say, but I CAN say is that I absolutely see longer cycles for quite some time after doing this.YMMV of course.
Whatever you consider "training" the battery, make 100% sure that the first full charge is indeed that: a FULL charge. This is one point that most documentation agrees upon. Getting the full use of the battery requires a FULL and complete first charge. Since I have no method to trickle charge, I tend to use the device while initial charging completes - I feel like that draws out the process, though why this is better. I can't say.
If only there was a definitive guide. Yes there are points in common among experts (such as running lithium ion fully charged all the time, especially warm, is terrible for them, yet almost all laptop makers let this happen by default when you run it on the charger (there is software to cycle the batteries), and some companies are including versions of this type of utility. Bottom line? batteries are cheap enough, but it's not ABOUT the money - It's about the run time. Heck - if I can't get good run time for a 3100 mA Battery, with a 2 amp charger, I better hang it up!
put the battery in, don't turn on the phone, and charge overnight. I know I know, this is the most difficult part. after that do whatever you like.
You are supposed to run the battery down every now and then(like every few months) What this does is it re calibrates the battery, separate from the android battery stat.
The batteries are tested and filled and drained then charged half way before packaged. A half of a charge is best for storage.
If your batter is dead when you open the box, exchange it. A battery sitting dead is really really bad. I have purchased a psp and some other devices that had DOA batteries and they never hold a charge for very long.
Android is the best I've seen with overcharging. Meaning there is none. The Android OS controls charging and doesn't allow the battery to fry like laptops do when plugged in all the time. I wouldn't worry about it with any Android device. Laptops should not stay plugged in for more than a few hours after full.
Running the battery down to zero (which is really 1-3%) is not "bad" what it really does is use up your charge/discharge cycle. Batteries have a certain number of charge/discharge cycles (like 300 or so) and running from full to dead to full every day will run the battery out faster; rather than charging it at half way or topping it off often.
please read post 11 and ignore anyone else who says anything to the contrary. i race radio control cars, we use lipo batteries, the system has a voltage cut off in the car for a reason. if you run them down too low, the cell will die, and will not take a charge. if you let them sit too long with a low charge, they will die. end of story. they do not need to be fully cycled like the old nicad batteries.
Dave
I say don't worry about it. The battery is replaceable and doesn't cost much. Enjoy your new toy any way you like and put battery worries out of your head.

Edit: Changed the title to make the answer easier to find. The battery popup killer mod has nothing to do with why the battery level drops after unplugging, as you will learn when you read the linked article. Now, on to my original post...
Pretty much every ROM for the Epic now incorporates the Battery Full Popup Killer mod at this point, but are we sure there aren't any unintended side effects of it? Is the battery charge state still being recorded to the batterystats.bin file? I know when you delete it through a file manager, or reset the stats through CWM, it does regenerate, but there is a lot more info in that file than just the full and empty charge levels of the battery, so it would be regenerated for the other services that use it.
I've had issues with my battery reporting that it's full, but only showing a charge of anywhere between 94-98%. Now, if my battery were actually defective, and losing capacity faster than normal, the batterystats.bin file should be compensating for that by recording the lower full charge level and adjusting the percent reporting accordingly, but it doesn't seem to be doing that.
So, are we sure the state of the battery is being recorded, even though the popup is being blocked? What else could be causing this issue with so many people reporting that their batteries aren't charging to full?
Questions need to go in the q&a section to keep the development section for pure development. Or as a reply on someones thread/rom. Although I have seen this question raised once before on mammons thread I think. I think the answer was that the battery is not set to charge to 100, and some other technictal details I can't remember. But from a day 1 owner of epic, my phone has never charged above 96-98, it will go to 100, but the second I pull it off charger down to 96-98. Even stock, with no mods to the battery popup notification. And now being on a rom that does have that no pop up notification, so I don't have to get woken up from a vibrating phone, there is no change. I'm sure someone else can give you the more detailed explination though.

I forgot that there was a Q&A thread in the development section, sorry to clutter things up. Thanks for the details, I'll see if I can find the Mammon thread that has the same question in it.
Hopefully this gets moved to the proper section as its a good question. Firon and I did some early work on this mod and I can tell you that we simply aimed at the graphical display and then stopped it from reporting. We didn't alter how it reports %s in anyway. I can also say that this issue is found in a stock epic right out of the box. My feelings are that the actual code for charging the battery is done this way on purpose which is lazy and over cautious imho, maybe they were worried about ruining batteries or even having one explode. Sounds like poor project management in any case.

OK, after searching through the threads for a little while, I found a very good article dealing with this issue.
http://www.androidpolice.com/2010/1...bump-charging-and-inconsistent-battery-drain/
Basically, the battery is supposed to charge to 100%, and then it stops charging to drop the battery level down to a safe level. It will then periodically charge the battery again to maintain a high (but safe) charge level, but never back to 100%. The batteries used in smartphones today aren't safe to keep at 100%, nor is it good for them (they corrode faster), so the charging system keeps them at a full, but not completely full state during the charging process. The phone will report the battery as being full while plugged in, even though it could be running fully on battery power at that moment and a few percentage points below 100%. It does this to make it easy for regular users to know when their phone is finished charging. It's only when you delve into the details that you start to see that the battery isn't actually fully charged, and start to rip your hair out when trying to figure out why it won't do it.
To sum up the entire article, it's supposed to do that. There isn't anything wrong with your battery, or your phone, it's done to prolong the life of the battery, and so the battery won't explode or catch fire by being held at 100% for too long.
The only time my battery meter reads 100% is when I pop a fresh battery in from my external charger.
Sent from my SPH-D700 using Tapatalk
I should have also added in my last post that bump charging does actually work, but will decrease the life of your battery. The experiment that the author of the linked article concluded that bump charging until the phone actually reads 100% while unplugged increased his battery charge by around 15%. Now, if holding your battery at 100% causes premature corrosion, it only makes sense that holding it at 115% causes corrosion at a greater rate.
If you absolutely must get the most time out of your battery, and are willing to buy a new one later on, go ahead a bump charge the **** out of that battery. The author suggests (and sites battery university as a source) that the best way to go about battery charging is to do several short charges throughout the day, rather than 1 deep charge from 0 to 100%.
Also, the author suggests that you stop obsessing on what the reported charge is telling you, and just use your phone.
Still makes no sense. They could code it to say 100% when its at 95% then so we atleast have the impression that its as full as could be safely. Like I said, over cautious and lazy imho...
sent by an Epic4g through the cosmos
Yeah, I suppose it is, but then it wouldn't be accurately reporting the battery level, which I guess is what Android's goal is. Personally, I'd prefer that if 95% is as much as I'm going to get out of a charge, than Android should just lie to me and tell me it's 100%.

I wonder if that's because the charge process brings the battery to 100% initially, then stops charging. Since the battery is in an external charger, there's nothing to draw power from it, so when it hits 100% and stops charging, it remains at 100% until there's a draw on the power.
I'm curious as to whether or not the user guide for the external charger mentions anything about not leaving your charged battery sit for a certain length of time. Based on the linked article, it's claimed that keeping the battery at 100% is damaging to it.

that's probably true about there not being anything to draw power when it's in the ext. charger. the funny thing is, I will pop in the fresh battery, and it will boot up the phone, and I can even do a several things, and the battery will still be at 100!
I try to take the battery out of the charger as soon as possible once it hits full charge, but I'm not always able to. I don't think there were any instructions wth the charger.... the whole thing was prety minimal: I paid my 12 bucks, or whatever, and never heard from them at all, until 2 weeks later an envelope arrived from China, containing only a charger and 2 batteries, lol.
I have both the Samsung OEM battery charger that they sell in the sprint store, and the cheepo Hong Kong charger that comes with knock off batteries. They both stop charging when the chip in the battery says it's full. Neither one had any documentation. I've seen zero negative effects from leaving any of my 5 oem batteries fully charged for long periods of time. The two knockoff batteries I had both died permenantly after about a month.

When they worked, they worked great. But one day I charged one up and stuck it in my pocket. When I stuck it in my phone, i got nothin. I took it home and put it back in the charger and the indicator light said it was fully charged but it was completely bone dead. Wouldn't take a charge at all. Same thing happened to the other one a couple weeks later. I have yet to have any problems with the oem batteries.
really nice article and it actually makes me feel a lot better. i thought it was attributed to certain ROMs somehow as i feel like i picked the phone up at 100 and it stayed there on some but not others. guess that was all placebo, lol. i think hte best part of the article is right at the end:
If you are someone who can top off your phone on a regular basis, do it. Plug it in when you’re at home. Plug it in when you’re at your desk. As explained by Battery University, "Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory."[2]
peace
Thanks for the informative thread
I'm ordering a spare battery; what is the best way to give it it's first charge / how should I condition it?
I don't think a lithium ion battery needs to be "conditioned" since it does not have the "memory" effect. It's usually the battery stats on the phone that can mess up the reading.
I would probably just make sure it is fully charged when switching them to be more accurate. But, I'm no expert...

Thanks for the reply.
I'm fairly sure I'd read somewhere that it should be fully charged before turning on the phone for the first time & after that do a couple full cycles (full-empty-full) etc..?
Yes, a full charge before using is recommended (I've also heard to let it sit on the charger for a couple more hours after it is charged helps) and maybe a few full "cycles" after that. But, like I said, I'm no expert and I, personally, have had no issues with my battery

True, it's not for the battery but for the phone stats. Lithium ion batteries are fully conditioned at the factory before being sent out. It's the last step in the actual cell manufacturing process.
Yes, I work for a lithium ion battery manufacturer. We make larger cells (not the tiny ones in a phone battery) but I have contacts and friends that work for other manufacturers that do make the little ones and they're basically all the same.
i ordered too 1800mah batteries cause i couldnt find any 1950s...they both arrived dead i waited 30 mins to charge and turn the phone on, and the other one is extremely dead it shows charging for a few minutes and then the red light turns off
so far the one i charged to 100% isnt working how i would have liked it dropped to 50% within a few hours and i charged it to 100 again and it dropped to 80 very quickly im gonna let it die tonight hopefully i get them to work good
Sorry about your bad experience.
Don't know what you purchased or the vendor, but I purchased a 3200 mAh batt from Siedio and am quite happy with it. I've been using it for over a month and get heavy use of my Atrix. High quality batteries are not cheap. Don't get the $20 dollar specials. (I have no financial interest in Siedio, I'm sure there are other vendors with quality batteries).
Battery calibration has been a challenge but I think I have a solution. I'll know in a few days as I'm presently recalibrating. It would have been so much easier if Moto had added a 5 cent current sensor to the phone.
I wouldn't worry too much about conditioning it. Just use it like you regularly would any other battery. Most horrible battery life comes from the way Android handles the battery stats. In my experience, most Li-ion batteries seem to really get their most effective use cycles after about a week or 2 of consistent usage. If you're experiencing some really drastic battery drops though, that's when it may be time to recalibrate the battery stats or start questioning the rom/radio/kernel that you're using.

Yep. However, unless you're impatient, charging it to full shouldn't do you any harm
For Lithium ion batteries, I've always put them immediately on the charger, let them go to 100%. Then unplug and let it completely die (that is, let it get so low the phone turns itself off) without pluging in. Then charge back to 100%. After that, use as normal. Doing this has gotten me long battery life, both short and long term compared to others I know who dont do that.
When I bought my phone the Bell representative said to fully charge then discharge the battery. I thought that you aren't supposed to do this though because Li-Ion batteries lose some of their maximum life when you do that. Only Ni-Cad batteries needed conditioning like that.
I could be wrong though. Would be nice to know proper procedure for this kind of thing

You're right, lithium ion batteries should not be fully discharged but it does help the first time to get the battery reading accurate. After that just charge whenever. It only really becomes a problem if you let it go dead too often.

+1. There's two reasons store reps tell you to discharge and charge the battery at least one complete cycle before using the phone. The first is that they're stuck in the past and think li-ion tech is the same as NiMH. The second and more sound reason is that it helps to set the battery statistics. If you're one of those people who loves to mod their phones right when they open the box, you could theoretically bypass this step by rooting and charging to 100%, and then just doing a manual battery recalibration by wiping the battery stats.

so far the one i charged to 100% isnt working how i would have liked it dropped to 50% within a few hours and i charged it to 100 again and it dropped to 80 very quickly im gonna let it die tonight hopefully i get them to work good

Yeah - if these are the Chinese jobs that came with the charger on Ebay, I got them too. They drop REALLY fast down to 5%, then I get at least another 24 hours out of them. It's crazy. I have tried to recalibrate by removing battery stats, but these haven't gotten any more accurate in several full charge / discharge cycles.
I suppose I will use them as spares, and just understand that the meter is not accurate on them. I still get a minimum two days with these cells. Will see how long they last. With batteries, you do get what you pay for.
so what is the best thing to do?
is there any way of charging,dis charging ect to get the best battery life?
or should i just charg it to 100% and use it right away?
i did a charging squence with my nexus s. but duno about the Gn.
for me is to turn on the device and start working until the battery drops to 0-1%.
only then im charging it X2 then needed to go to 100%, you can make it Double if you want.
Well, this is going to be one of those threads where everyone has their own little way to care for a battery and others say their way is better, etc, etc the arguments breaking out which will result in people posting www.batteryuniversity.com in an effort to win said arguments.
Here's mine. On a brand new phone, I put the battery in, boot up, connect the charger, run it to 100%, disconnect charge, run battery all the way down, connect the charge, run to 100% and go about my life charging when I need to.
My two cents. Have no idea if it does any good, but my SGSII is going on 1 day 14 hrs on a single charge, so it must work somehow...

My way,
Turn on phone, charge it to 100%, leave it plugged for an extra 20 min, and start using it normally.
The only time I discharge a battery is after a couple of months. Because we never charge it to 100% and they start creating memory and charging less and less every time. The purpose of discharging it completely is to erase its memory. That's why when it is new, I see no point on discharging it completely. Batteries suffer every time they are completely discharged and if they are left 100% for a long period of time, thats why new batteries always come charged about 50%, to extend battery life since they may be stored for a long period of time. (ref. aviation school)
Just my 2 cents.

That hasn't been true since NiCd's in the 1980s.
Modern Lithium-Ion and Lithium-Polymer batteries have no "memory" and are actively damaged if allowed to discharge fully.

Generally because they don't know any better and they don't realise battery technology has moved on.
Because batteries "back in the days" were quite sensitive to memory. That's why we were all raised by the complete-discharge-mantra, which sticks with you forever. The next generation won't have this problem and will feel free to charge their phones when they want to. ;-)

Becouse android in itself keeps a battery log, it is from this log your device calculates the amount of battery you have left. To keep these values true (calibrated) you should do 2-3 cycles where you on purchase, discharge fully until device auto shut down, start it WITHOUT charge a couple of times and let it die to set the min value, charge up to 100%, use your device again till auto shut down... you dont have to worry about damaging your battery in this case since your device it programmed to shut down with good marginal of battery depletion. What you SHOULD NOT do is leave an empty battery uncharged for a long period of time.

Lithium batteries will be damaged if they are stored fully charged or fully discharged for extended periods of time. Thats why the battery is about half charged when its new. They have no memory effect, they just loose capacity.

Good point. While it's important not to fully discharge the battery too often, there is also the issue of calibrating the battery meter.

The whole "discharging the battery fully" thing doesn't really apply here - because nobody will ever fully discharge it. The Nexus uses a Lithium Ion cell - it's a single cell, with a nominal voltage of 3.6V. When fully charged, it peaks at 4.2V (at which point, the charging circuitry cuts off to avoid overcharging). However, when we "fully discharge" our phones, the cell only goes as low as 3.5V - and then the phone shuts off.
In reality, lithium cells can discharge to around 3.0V before any damage occurs. However, this would yield very little extra battery life. Stopping at 3.5V provides a wide safety margin (lithium cells are potentially dangerous if overcharged/discharged), whilst extending cell life.
In a nutshell - don't worry about running your phone down to 0% (unless you're putting it in storage, in which case leave it at about 60%). In fact, it's a good thing with a new phone, as cycling (charging and discharging a cell) helps to "wake" the cell up and reach it's max capacity more quickly.

i see some good ideas about charging and discharging.
but it is indeed a fact that 100% and 0%(real) isnt good for our new race of battery's.
but a few posts here already tell how and what.
and its not gonna be a thread of arguments and stuff,if we all keep it in our heads that we just want to share our tip's of how you think its the best way(and have some experience with it)
just to share some info. and not compete the info against each other.
i well know there are different ways. but its always nice to read what experience people have with it to make a choice for my own and any other wanting to know this.
and i posted here in the GN section,instead of the Android section because each phone handles battery different,and this narrows the options down to a single device :3
Just keep in mind it's not just about the battery itself it's about the software registering how much actual power the battery has at a certain time, so if the battery has in actuality 100% charge in it, and the software reads 80 then your phone will die out sooner. So charging and discharging is good because it calibrates the hardware with the software. Just remember to switch off the device then charge it so the software doesn't auto discharge when it thinks the battery reached 100%.
K i just skipped thru the posts, gonna throw in my input real quick.
Basically just run down the battery. Once it turns off, hold the power button to make sure all the juice is gone. Then charge it up to 100% and leave it there for a good hour. Now (root required) download https://market.android.com/details?...yLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd and follow the instructions .. its not exactly necessary but a nice thing "just in case" .
thats my plan anyways.

Won't make a difference.. Phones are designed to be left on anyway.
What is best in terms of battery longevity?
1 - Wait until battery level fall below a certain level (and which % is ideal to start charging)
or
2- Charge the battery as frequently soon as possible
Thanks for any advice
Lithium batteries last longer if you do not disharge them all the way..
I don't have reference material handy. If you really want some, I will try and find some again..
But basically charge the battery whenever you can or at least do not let it go below say 20 or 25 percent if you are concerned about that. Since our devices have a replaceable battery I do not stress out over it too much. If I cut 6 months off the battery and it only lasts me a year or so, I can always just put in a new one, they are not that expensive..
Now on a device without a replaceable battery is where you really have to be concerned..
Drain till 20% then recharge it. Best way to use lithium battery.

i'll run my phone down tonight and check it with a mutlimeter to verify...
i wouldn't be surprised to find out the phone stops charging the battery before it's at a true 100% either. so i guess i'll check that too.

I was also puzzled by the warning of overcharging issue. I read somewhere that the GalNexus has an electronic which prevents overcharging. I am very interested by your verification if that is true. Because frankly, it would be very inconvenient to wake in the middle of every night to disconnect the charger.

there are wall chargers that have timers on them, they shut off power after a custom time
You can't overcharge a phone by leaving it plugged in all night, the charging circuit only allows it to charge to a certain point. You can overcharge a phone by plugging it in everytime it hits 90% because you're being all OCD about it. Over time that will screw up your battery
The main thing you want to avoid is heat, which will seriously degrade the life of the battery. I only charge my phone once a day(before I go to bed). I've been doing this since I got my first Android device(well, my Nexus S had to be charged like 3 times a day :| ) and have never run into any premature battery failures.

Quite the opposite is true, regarding the second part of your reply, actually.

Actually, it's never a bad time to charge a lithium battery because the charge you are using is always the oldest added. Consider it as a bucket with golf balls and a hole at the bottom. You load golf balls from the top and use them one at a time from the hole on the bottom.
All lithium batteries have circuitry built into them to prevent overcharging but at the same time the circuitry needs power to operate. If you drain your battery down to nothing and leave it uncharged for a long time the circuitry will drain the reserve and you will not be able to charge it at all.
Another fact about lithium batteries is that you can charge them more times than their natural life span. So as soon as a battery is manufactured it starts to go bad just sitting on a shelf. So buy them fresh. They have thousands of charge cycles and only about 2-3 years life. So even if you charge all cells inside 2-3 times daily (remember the bucket analogy) that's only about 1,000 charges in a year.
Also, you could plug your phone in and out 100 times during one day and still not complete one full charge cycle.
Conclusion ; charge it whenever you can, whenever you want. You'll need a new battery in about 2-3 years anyway in which time you'll most likely get a new phone.

I would say they are not only old but also fake claims of capacity. It's actually hard to measure how much a battery can hold so they take advantage of it. Who's going to prove them wrong?
system shutdown occurs on the Galaxy Nexus at 3.39 volts (assumed, measured voltage with no load is 3.42)
in theory you could get a bit better battery life at the cost of cell longevity by running it down to 3.2 volts. assuming the system could continue to function.
EDIT: full system charge is 4.2 volts, as expected. i don't see a practical benefit to modifying the system to run at below 3.4 volts, even if possible.
Hey guys I'm often a lurker on here and don't post a whole lot but came across this article and found it interesting. Thought I'd share... Also, I like to leave my HTC ONE plugged in on my desk stand at work with the "Daydream" clock function running (basically using my phone as a desk clock). Do you think leaving it plugged in charging all day running this clock is doing any damage to my battery? It of course fills up and charges to 100% pretty quickly because I never really let it get below 80%. Below is my charging habit...
1. Charges all night at my bedside
2. Take it off the charger in the morning while getting ready for work and my drive
3. Get to work, plug it in for 6-7 hours running Daydream
4. Take it off the charger and go home... (off the charger for about 4-5 hours in the evening)
5. Go to bed, plug it in, and start all over again...

How To Take Care of Your Smartphone Battery the Right Way
Click to expand...
Click to collapse
Your smartphone is a minor miracle, a pocket-sized computer that can fulfill almost every whim. But none of its superpowers matter a bit if it runs out of juice. With removable batteries becoming more and more rare, you've got to take good care of the one you got. Fortunately, it's not to hard keep the lithium-ion powering your everything machine happy if you follow a few simple rules.
Obviously, the first rule for extending your battery life is not using up all your battery life playing candy crush and walking around with Wi-Fi and GPS enabled when you're not using either and really, really need your phone to last that extra hour. But aside from that, there are some basic rules for care and charging, and they're the simplest baseline for a healthy battery.
Top it off
You may vaguely recall hearing something about rechargeable batteries and the "memory effect." You know, that if you don't "teach" your rechargeable batteries their full potential by taking them from totally full to totally empty, they'll "forget" part of their capacity. Well forget all that. Right now. It's wrong.
To get the most out of a lithium-ion battery, you should try to keep it north of 50 percent as much as possible. For the most part going from all the way full to all the way empty won't help; in fact, it'll do a little damage if you do it too often. That said, it's smart to do one full discharge about once a month for "calibration," but don't do it all the time. Running the whole gamut on a regular basis won't make your battery explode or anything, but it will shorten its lifespan.
So if you're really particular about optimizing your battery's life, you should try to go from around 40 percent to around 80 percent in one go, and then back down whenever possible. A bunch of tiny charges isn't as bad as going from 100 down to zero all the time, but it's not optimal either.
Keep it cool
It's easy to worry about bad charging habits thanks to the training we've had from old rechargeable batteries, but lithium-ion batteries have a worse enemy: heat. Your smartphone's battery will degrade much much faster when it's hot, regardless of whether it's being used or just sitting around doing nothing.
At an average temperature of 32 degrees fahrenheit, a lithium-ion battery will lose six percent of its maximum capacity per year. At 77 degrees, that number jumps to 20 percent, and at 104 degrees it's a whopping 35. Sure, it's not exactly practical (or sane) to keep your phone in the fridge, but it's worth going out of your way to prevent long stays in hot cars and the like.
Avoid wireless charging
Wireless charging is can be incredibly convenient if your phone can do it, but it's not without its disadvantages. The inductive, wireless chargers out there today have this nasty habit of generating a fair bit of waste heat. And while wasted energy is just a bummer in general, that heat will also toast your battery in the process. That's no bueno. It's a little less convenient, but standard plug-in charging is going to keep your battery in better shape, especially if you're some place warm to begin with.
Never go to zero
Obviously, using your battery is going to make it degrade. But it's going to slowly die even if you just leave that iPad in the closet for a bit. There's a trick to minimizing that inevitable aging though: leave it a little bit of juice.
If you're going to be shelving any lithium-ion battery for a long time, try to leave it with at least 40 percent battery power to tide it over. Lithium-ion batteries don't hemmorage power at 30 percent a month like nickel-metal-hydride batteries do; they'll lose maybe five to ten percent of their charge each month.
And when lithium-ion batteries get too low—like, literally zero percent—they get seriously unstable, and dangerous to charge. To prevent explosion-type disasters if you do try to charge one, lithium-ion batteries have built-in self-destruct circuits that will disable (read: destroy) the battery for good, if it reaches rock bottom. And sure, that'll save you from a face full of battery-acid, but it'll also leave you short one battery.
Don't sweat it too much
It's easy to get protective of your battery, but it's also easy to get lazy. And that's fine, because as long as you're not a complete idiot, you'll be OK. Typically, a lithium-ion battery lasts for three to five years, and chances are you're going to want to swap out your gadgets sometime in that window anyway. The slight damage of a technically bad idea like leaving your phone plugged in all night every night, or using wireless charging, might be worth the convenience.
Still, it's pretty easy to keep your battery reasonably healthy just by avoiding particularly egregious torture like letting your phone discharge from full to zero every single day, or leaving it in a hot car all the time. And the next time you make it back home with power to spare, you'll thank yourself for it.

I dont agree that your battery dosent like being or performs worse at a 100%. Or that it harms the battery in any way. I keep my phone plugged in as much as possible durring the day, and all night long. But i only use the wall charger that came with the phone, or a smart car charger made for my phone. Because as the article says, these chargers are smart enough to stop charging for awile after the phone has reached 100% to prevent over charging/heating. Cheap wall and car chargers dont have this feature and continuously provide a charge to the phone. Also charging using a usb port on a pc or other device does not provide this overgharge protection.
My last phones battery lasted for almost 3 1/2 years before needing to be replaced. Heres what i do.
Keep it charging as much as possible only with a "smart" charger.
Never let the batter drain all the way down. If it gets to 10% and i cant charge it at the moment, i turn it off.
Never let your device get too hot. Dont leave it in hot cars or sitting in the sun, etc.
Never "bump charge". That is just a way to trick a smart charger into overcharging your battery.
Also over clocking/volting your phone puts more strain on your battery than it was intended to take. It makes its temperatures rise higher, and the charge to deplete in a more rapid fassion. Both of which are bad for your battery.
These are just my opinions of course, but it seems to work out good for me. I think 3 1/2 years is a pretty acceptable life span.
never let it die
I have always left my phone's plugged in constantly and never an issue. Once my phone hits 100% it stops charging and then is very cool to the touch from then on.I heard phone's now has a failsafe that will stop charging and start running the phone off the charger and not battery.

What's the best battery conservative rom?
Why do you think you should never fully drain it?
Every 30-40 days, you should fully drain your battery - until your phone automatically powers down - and then fully charge it - and allow it to stay on the charger for 30-40 minutes after it's 100%.

The battery management system in the phone does not allow the cells to go lower than the safe level. For Li-ion cells, that's somewhere around 2.7-3.0volts/cell.
If it did, there'd be not only a huge warranty liability, but also a safety one.

You can believe that if you want to but if you actually read that link you will understand. It puts a lot of strain on the cells to go that far down. There is a physical reaction inside your battery of growing and stretching created from the charge/discharge cycle. If you regularly drop the charge to nothing then it makes it harder for it to keep a charge over time. You're more than welcome to do your method of calibration but I'm a firm believer in keeping the battery healthy.

I didn't say regularly. I said every 30-40 days. I have a lot of experience with lithium cells - both manufacturing and selling.
Before getting the One, I regularly used my HiTec lithium charger on my thunderbolt battery to run a discharge cycle, and then balance/charge it slowly.
No one need be afraid of their phone getting below 10%. It isn't causing any damage.
Well i guess its all a matter of opinion. Me and my wifes first smart phones were the htc incredible. I would never let mine die and the battery lasted fir 3 1/2 years. My wife would let hers die once or twice a month, and it lasted for 14 months before it needed a new battery. Got on her about not letting it die after we replaced the battery, much to my surprise she listened, and the replacement lasted for another 2 1/2 years. Both of our batteries actually still work today just not used to much anymore.
I had the dinc2 and followed the same procedure he used and pretty much nuked a battery from doing that same procedure. In less than a year my battery was bad. To each their own but I still don't suggest running it all the way out.

even anker, who is is probably the biggest portable battery manufacturer recommends not letting their products get below 25% because it can reduce the lifespan of the pack. They state that keeping it between 25-75% is ideal.
Interesting article, thanks for sharing OP.
I also leave my phone plugged in while sitting at my desk and let it charge up. Typically I plug into my laptop via usb while at work, once fully charged it shows 'fully charged' and switches the led status light to green.
I try to never let it die either but have to travel for work and do get very low on occasion, once I get down to 10% I typically just shut to phone off to preserve power while I am flying and avoid turning it back on again til I can get it on a charger.
Battery Life
I'm new to this phone,so I'm not entirely sure how the battery life is ... but I heard a while ago that you get the best battery life out of phones when you only plug them in to charge when they are completely dead. I don't do it often enough to see a difference, but has anybody else done it?
You probably get a much more consistent charge while it is dead/powered off. The only problem there is does letting your phone die occasionally ruin your battery or not?

Did you not read the first message in this thread. wherein it says:
To get the most out of a lithium-ion battery, you should try to keep it north of 50 percent as much as possible.
and
Never go to zero.
Alright, alright - I was merely saying I'd heard a theory stating otherwise.

My laptop, which is a Lenovo, has 2 settings. Best battery health and best battery life. Best health keeps the battery charged to between 50-60 percent and then stops the charge. Best life goes up to 100.
