before everybody tells me the search function, I already have but I find mixed and contradiction answers on this issue. Some people say to do a full discharge followed by a full recharge as soon as you get the phone. Then on the other hand some people say that you shouldn't do this since the x1 uses a li-ion and its bad for it. Some people say you should charge it only when it's near empty, but on the other hand some people say to keep charging it as often as possible. Some say to take it off the charger once its fully charged, but then some say its ok to leave a fully charged battery on the charger.
As you can see, from searching the forum I've gotten pretty confused. so what is the PROPER way to charge our x1 battery? Is it also true that battery life gets better the more you put it on the charger? Does the x1i get better battery life than the x1a? I'm asking this because I'm gettin very poor battery life on my x1 compared to the 1-3 days of heavy usage that I see other people gettin on this forum. I'm going to exchange it today for a new one, so I don't want to make the same mistakes with charging my battery as I did with the first one.
Charging:
Do charge the battery often.
The battery lasts longer with partial rather than full discharges.
Discharging:
Avoid full cycle because of wear.
80% depth-of-discharge recommended.
Re- charge more often. Avoid full discharge.
Low voltage may cut off safety circuit.

that is very true......i get better life (3days) when i charge from 50%. otherwise i barely get more than 24hr.
thanks, that helps a lot! but what do I do once the battery has finished fully charging on the charger? should I take it off or is it fine to still leave it on the charger?
i have noticed this today,
i have installed a battery indicator bar (i cant remember which one) i charged my my X1 during night, when i woke up, i found that the phone is not charging and the battery is full. so i think that the phone automatically stopps charging when the battery reaches 100%
anyone can confirm that?
Not sure about the way to charge it, but i can comment on your current battery life. when i got mine, i had 1 days battery life, but after flashing it, i'm now getting between 3-4 days......

Glad to see that there are people that read the "real" stuff (I'm talking about dogans), the batteryuniversity site is mantained by the very battery fabricants, so their opinions are the best informed ones, even if they might bias a little to keep the bussiness "healthy".
However, any Lithium battery should not be fully discharged -at least not often-, because the full discharge shortens their life.
Usually, good chargers do control the charging parameters (battery's voltage, current and temperature curves) while it charges and "know" when to stop, even if they really don't stop ever (normally), the go in "tickle" charging mode, to keep the battery "fully" charged.
Hope this helps.
The article on Wikipedia about Li-Ion batteries is quite informative as well:
http://en.wikipedia.org/wiki/Lithium_ion_battery
It specifies the technology, the do's, the dont's and usefull tips in keeping your battery in good condition.
At the office I leave my phone in a cradle. When I get calls I remove the phone to answer and then return it to the cradle when done. My battery goes from 100% down to somewhere in the 90's then charges back to 100% in the cradle. Does this repeated process harm the battery in any way? I've read that these batteries don't suffer from the memory effect, but I'm still not sure if this counts as a charging cycle.

You should always let the battery run down completely some times maybe once a week.
Really? I've read on this forum that there is no need to do that with the new Lithium Ion batteries. I've even read that this could have a negative effect and you should try not to let the battery drain completly.
I don't understand why there isn't a proper battery care section in the manual. Its as if its some kind of voodoo science.
Perhaps not Once a week. But Once a "while"
The reason is that, Phone software uses approximation to calculate the charge left in the Battery. So over time, battery ages and software may not be calibrated to match with the battery's storage capacity. So draining the battery entirely and charging them fully gives the phone's software to assess the battery's health and recalibrate.
It's a lithium battery mate. The only way you can really damage it is by a complete discharge. So long as you don't switch the phone back on once it switches itself off due to low battery you needn't worry about anything else.
Also in theory the lithium batteries have a lifespan of say about a 1000 charges for example and everytime you charge it has one charging less left. This ofcourse isn't exactly how it is in practice but charging the battery alot wears it down. It isn't good either to keep it in the charger for a longer time after it's reached a 100%.
Hi,
this is only partly correct:
Suppose the battery can make 1000 (which I don't believe) charge cycles,
it means that you can charge 1000 times from empty to full.
If you just charge 1000 times from 50% empty to full it counts for 500 cycles!
So,
don't worry, let it stay in the cradle if you like
There are 500 opinions about that but believe, as I wrote is correct.
Theo
Yes, what I said wasn't exact science and I used 1000 cycles as an example, but from what I've read it is better to let the battery drain to less than 50% and then charge it full rather than charge 5% at a time. My previous post was meant to illustrate this.

That's a load of crap, no offense... Lithium batteries have no memory effect and have absolutely no need to be completely discharged, that's a ancient thing from the time of nickel-metal hybrid batteries. The only actual reason for full charge cycles is to calibrate the device for that exact battery.
Keeping a lithium-ion battery in a charger most of the time will wear the battery down faster than getting it drain more and then charging it. Keeping the battery almost fully loaded/in a constant loading state wears the battery capacity by approximately 20% a year (can't recall the source/study just now)(EDIT: and my personal experience is that the battery capacity will wear that much anyway, no matter how you use it). The life-cycle of phones these days are roughly two years nowadays so IMO you can keep it in a cradle with no worries, if you wish. And lets face it, a new battery after a year of usage won't be that big an investment after all.
To add to the above post, running down a lithium battery completely does more damage than benefit. This is almost impossible though with normal use as the phone shuts down long before the battery is completely empty
Is this the definitive way to do it?
http://hemorrdroids.net/battery-calibration/
Those steps came from here, xda devs.
1. Run the device down until it turns itself off.
2. Turn it back on and wait for it to turn itself off again.
3. Remove the battery for 10 seconds.
4. Replace the battery, but leave the device off.
5. Charge the device until full and then for another hour.
6 **Root users only** Using a Terminal Emulator, type “su” enter, followed by “rm /data/system/batterystats.bin”
7. Run the device’s battery down until it turns itself off.
8 .Turn the device on and charge for at least 8 hours.
9. Unplug the device, turn off, then charge for another hour.
10. Unplug the device, turn on, wait 2 minutes.
11.Turn off again and charge for another hour.
12. Restart and use as normal.
Quite a performance! Does it preserve battery lifespan, or is it more to do with slowing down battery drain and does it really work?
He mentions 2 interesting things:
"Generally charge them before they get lower than 50%". I didn't know that, so it's actually better to charge more often and not let it drain down?
"USB charging is actually better for the battery and you may get up to 1 hours more standby time." So you gain an hour standby but it takes twice as long to charge the phone.
Nice manual
Will try it

Some will say that its complete nonsense .
Overcharge for 8 hours ??? how does the battery not turn charging off at 100%
Recharge 50% the accepted figure is not to go below 20% to often .
They may be right or wrong their are so many contrasting views on battery charging .

Discharging battery and then reloading it fully, it's the normal procedure for battery calibration for almost all the devices in the world (including computers, etc.).
Step 8 to 11 seems quite a bit strange however.
hm, just seen a different way to calibrate the battery. basically, you drain the battery, take it out for a couple of minutes, put back in, then try to turn it on to make sure it's completely flat.
then you charge it fully, then boot to recovery and wipe battery stats then drain and fully charge. so... which one is more likely to be the better?
that guy also advises to repeat that 12 step, 1-2 day long tedious procedure "every month or so".
it is lunacy honestly speaking
does it work? did he died ?
LOL I dont understand .... I just read in another day that NEVER LET BATTERY GO LOWER THAN 15% and know I read "drain drain drain" Oh welll ...
I also thought that at 100% the charging process stops.
Although this thread is about battery calibration, these questions about battery charging always pop up.
Battery calibration is the process by which you set your device with your battery data.
Every single battery is slightly different. Although there are minimum stantards to every spec of the battery, each battery is different.
Calibrating your battery is nothing more than setting your phone to the real specs of your own battery (since the phone comes configured with the battery factory standards). For example, your phone may be set to use a battery which maximum charge is 1650 mAh, but your battery has a maximum charge of 1625 mAh. That may be within the acceptable factory standard, meaning you have a normal battery, but that also means that your phone will never indicate a 100% charge after you unplug the charger.
If you calibrate that hypothetical battery, you will "tell" your phone that its maximum charge capacity is actually 1625 mAh, meaning from that on your phone's battery indicator will be more accurate.
For that reason, it is necessary to fully discharge and fully recharge your battery for the calibration process, since your device must read the actual specs (minimum charge, maximum charge, charging current, etc) of the installed battery.
I don't know about how many times this full cicle (discharging and recharging) must be performed, but that is the reason why it must be performed for the calibration to succed.
A DIFFERENT THING is the normal discharging and charging process during normal use of the phone.
In this case, you should NEVER let your battery go under 20% and, what few people know, it also should never go over 95%. This stresses the battery and diminish its life time.
Also, and there's a lot of doubts about this, the lower the charging voltage, the slower the charging process, but the longer the battery life.
High charging voltages (like the one used by the charger sold with the phone, which is around 5V) stress the battery, diminishing considerably its life time.
That is true for all lithium-ion batteries!
Therefore it is better to charge your phone through USB (which uses around 4,3V) than to do it using the charger provided with the phone.
You may be asking "If the charging voltage of the charger provided by the manufacturer stresses the battery, why does the manufacturer provide such charger?"
For purely commercial reasons! Higher voltages mean shorter charging cycles, which please the consummer. Moreover, the battery capacity loss with the factory provided charger is around 15-20% a year (considering "normal" to "heavy" use). That is to say that after a year your battery will only reach 80-85% of the maximum charge it used to reach when it was new. And by that time your manufacturer expects you to consider buying a new phone, with more features.
Summing it up:
- calibration is just the process by which you "tell" your phone what the real specs of your battery;
- in normal use, charging your phone through USB is better than doing it with the manufacturer provided charger;
- try not to let your battery charge go under 20% nor above 95%;

Spin three times in clockwise direction with left middle finger on your nose while blinking your eyes with the phone plugged in.
Jump in the air 3 times.
Unplug phone.
Thats some messed up instructions.
Do you have any idea what kind of strain you're putting on the battery while doing all that?
All you're gonna get is some extra minutes, maybe an hour but is it really worth it because you're just reducing overall battery lifespan by doing that procedure over and over.
Specially when you constantly keep the battery at 4200mV (full charge) for a long time. You're practically killing it by overcharging.

Never done a calibration on a battery and most of the time i even didn't let battery to discarge very much and then load it again. Never had a problem with battery life it last how long it should last every time and i've used that battery for years. So the battery "calibration" are kinda useless.

The OEM replacement battery is worth about $10.
Save yourself the stress....use it...charge it when you need to...if the battery ever fails cough up $10.

The way I would calibrate my batteries is a bit different. Lithium ion batteries don't need to be drained then charged to full AFAIK, and I even remember reading somewhere that draining it is actually only for NiCad batteries. It used to be relevant when phones were using NiCad but not anymore.
Read: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
As such I have read that the universal way to 'calibrate' batteries is by charging to full, using for a couple of mins and charging again.
What I have been doing is:
1. Charge to full when phone is switched off (doesn't matter if it's from 0% or 99%).
2. Switch on the phone, use for 5 mins.
3. Switch off then charge until full.
4. Repeat step 2 once more
That's it! It seems pretty simple but it seems to have worked for me.
The way i do it is different. Firstly i have the battery calibration app from the market by Nema..then i fully charge my phone and when it says its fully charge i go into the app. There it gives me the instructions on how to calibrate...First i wait till i charge the phone without any interruptions. then click on the app and wait til the battery goes to 4200MV and then i press the calibrate button and then the app does it for me. Then i drain the battery again without any interuptions or breaks during that time and then charge it again once battery dies down and thats it.
there are so many ways being touted on the forums you really dont know which one to go for...but whatever works for each person then who are we to tell someone different just thought i share that
If my battery dies, or gets significally lower capacity after 1 or 2 years of usage, I'll just buy a new one if I plan to keep the phone longer.. Going through these rituals and painstakenly monitor my battery % so that it never goes below 20 % or above 95 % is just not worth it.. Doesn't increase the life THAT much anyway.. I use the phone until I hear the beep for low batt, and from there until I have a charger available.. Most of the time it's before it reaches 10 %, thats good enough for me.. Once in a while it might even go so far that it dies.. Then I charge it till it says 100 %.. Most of the times I plug it when going to bed, and let it charge over night.. This is normal usage and what the battery should be designed to handle, and so far it does..
When charging The ZeroLemon battery, you should always charge at the "Lowest Amperage" meaning Fast charge should "always" be turned OFF when charging any ZeroLemon batteries. Leaving the fast charge turned on will charge the battery faster, of course. However, it will "kill" the ZeroLemon battery over time, reducing it's charging life to a mere crappy timespan, and also reducing it's ability to distribute a charge for the device over the original intended time cycle. >This info is straight from ZeroLemon themselves. This is not just my opinion.<I have purchased many batteries from ZeroLemon, on my business account, and this is what they themselves, and their USA distributor instructed us to do for the absolute best performance of their battery.
Another thing to keep in mind is when charging the battery on the slow, non fast charge cycle. To always charge with the phone off. No, this isn't so the phone can charge the battery faster. It's so the battery will get the "Full Charge" it's intended to receive. What do I mean, you might ask? When charging the OEM factory battery, the software is programmed to look at the /data/system/batterystats.bin file to determine calculative information and statistical information about the battery itself. This information guides the system on where the battery is at its charge cycle along with various other related task.
Zerolemon clearly states: "Shut down, plug in the power supply and charge until full. (Preferably continuously charge overnight to ensure maximum power. Remember to not switch the phone on, until battery is fully charged.)"
So how do you know if this monster of a battery is fully charged? Well, there's a couple ways. You can look at the whitepapers or on the battery and get the full amperage/voltage cycle information, or you can simply use some simple math to determine what amount charge you're charging at and then determine the amount of hours it will take for a complete full charge.
Now, I can make this a little easy for you and help you out with this. If the battery is brand new, meaning it just literally arrived and you just opened it from the box. Charge for afull 12-18 hoursfor the first charge. Do this with the phone off. When you hit that time mark, you can turn the phone on for use. Now keep in mind I said 18-24 hours for the first charge. Since Zerolemon sends out the battery with some bit of a charge on it, it's impossible to get the exact amount of charge for sure. So when in doubt, charge it fully out. That means 18-24 hours. Yes, yes, that's one hell of a long charge. But let me tell you. I use my phone all day. Full screen brightness, everything turned on, Bluetooth, Wi-Fi, etc. Watch videos, games, hit the forums, obviously . And I always get 3 to 4 days of use. That's right baby. 3 to 4 days of use. The secret is the long slow charge. These batteries are not single cell, they are a tricell makeup. The slower and longer the charge, the longer the battery will last.
Now back to the charging cyle info. You've already charged the phone up completely for the first time. Now use that sucka! And I mean use it till it completely gets to 5% and the system forces you that crappy power save mode where it dims the display etc. Power the phone off. Remove just enough of the rubber TPU case to lift up the battery from the contacts. Count to 3, then replace the battery, TPU, etc. Don't be shocked when you power it back on and you've got 80% full battery again. Remember this is a tricell, so it doesn't report correctly what the exact amperage/voltage is to the android system. Now continue to use the battery and repeat until the battery is at 5% all the time when reinserting it again.
Now, the step above is where everyone messes up and just depletes the battery to 5% only "one time" and then goes to charge the battery again. Don't do it! You're cheating yourself out of precious battery life.Follow the above cycle exactly as I said and you'll be thanking me later, that I promise. If you've already had the battery for a while and been charging it incorrectly, don't worry. Deplete the battery as outlined above, then charge for 18-24 hours, remove battery, insert battery, repeat till stays continually at 5% then recharge.
OK. Now let's move on. Once you continually hit that 5%, Start the charge cycle over again by charging the phone with Fast Charge turned OFF, the full 18-24 hours. Then repeat the steps outlined above again.
>>IT'S EXTREMELY IMPERATIVE THAT YOU DO THIS 5 CYCLES.<< (Sorry for the caps, but really need to stress the importance of this.)
Once you have completed the five cycles, you're on your way to always leaving that blasted charger at home, and never again being thought of as a "Wall Hugger" if you've seen the commercials .
=> Don’t stop charging even it shows 100% charged. And if you're seeing this 100%, then you didn't turn off the phone during the charge as indicated above, lol. A true "Full Charge" is only performed when the battery has been charged for 18-24 hours.
Charging Scenario
When you are doing the first "5 Full charge and Deplete cycles", the phone must be powered "off" while charging. This is due to the android operating system and the Note 4 thinking the phone is fully charged when it reaches 100% even though in reality it's truly not. The Zerolemon battery may only be in reality at 30%, 40%, 50%, etc. Remember, the device believes it has the OEM factory battery in it, and not the massive Zerolemon battery. Unfortunately if you're not rooted with a Developers Edition Note 4, it cannot differentiate between the two batteries. So for the first 5 full charges, (this is referred to as the conditioning of the battery,) turn the phone off when charging.
Now after the 5 cycles have been completed, and the conditioning has been done. You can charge the battery with the phone on. However its important to remember that:
1. When your little battery icon shows full, or if you have the battery % on, & it shows 100%, don't stop charging. It thinks you have the Factory OEM battery in place. To ensure that you have a "True Full Charge" the total noninterrupted charge time must be no shorter than 18 hours and no more than 24, if the battery is truly fully depleted.
2. Properly charging a battery of this size works as follows. The battery has been charged 18-24 hours and is fully charged. You use the device depleting the battery over a period of a few days, while in the process, when it hits 5% you remove the battery and then reinsert as mentioned earlier, then continue to use the device till the battery is actually fully depleted. This means the phone won't power on anymore.
Now at this point, you'd start the charging process again, for 18-24 hours.
Do not charge at every day or every night just because the battery is a little low. (Because almost devices are powerful hungry and batteries depletion is very quick, people are in a habit of just throwing it on charge whenever and however.) Only charge when the device is completely and fully powerless.
Routinely charging the Zerolemon battery in different increments will cause a severe and nonreversible battery retention that will prevent the battery from not only being able to give full use, but prevent it from being able to be fully charged anymore.
TIPS:
Zerolemon batteries for the Note 4 are notorious for prematurely shutting down the phone by means of loss of power if the phone is dropped or in some cases even bumped. The reason this occurs is because their is a small discrepancy in the exact battery size where the contacts meet the pins on the phone. In layman's terms, the Zerolemon battery is just a bit short. No, it's not gonna fall out of the back of the TPU case or anything like that. However, if you drop the phone, or even in some reported cases, bump the phone, the Zerolemons battery loses connection with the gold contacts from the device from within the battery compartment.
Reports have been made to Zerolemon concerning the issue, however Zerolemon has failed still yet, to resolve the problem accordingly. Most likely because just a simple change of plan, would literally open the door for thousands of recalls, refunds, etc, not to mention cost thousands of dollars to remap the sizing and make the correction to future batteries.
Well with this said, all is not lost. I've found, if you remove the TPU case, leaving the battery in place, you can insert a small shim of paper at the proper place, and this will totally resolve and eliminate the problem 100%.
You can use paper, plastic, Thin gasket material etc. Whichever is most convenient for you at the time.
The proper placing of the paper is crucial. Because you don't want to cover up the path to the speaker phone compartment any more than it already is.
Here's the easiest way to fix it.
Power off your phone. Now remove the TPU case and lay the phone carefully screen down so the battery compartment is facing upwards. Position the phone where the bottom of the battery compartment is closest to you, and the camera is furthest from you. Now remove the battery. On the bottom right side of the battery compartment you will want to insert your paper, plastic, "fix" etc to the bottom right side of the compartment. The paper thickness I'd recommend would be the thickness of a regular matchbook cover, or about 2 sheets of construction paper. The dimensions I used was about 1/8 inch tall, by 1 inch long. Don't lay the paper flat inside the battery compartment, doing so will cause the battery to be a little "thicker" and not make connection. You will want to "Stand Up" the little piece if paper, or if you're feeling savy enough, permanently afix the paper to the housing. Now when you go to reinsert your Zerolemons battery, you'll notice that it not only actually first a little tighter and snugger, like it should have been on day 1. But it also doesn't let the battery wiggle a little like before. Replace your TPU case, and power on your phone.
I'll upload some pics for you to show you how I did mine. If you got any questions on any of this, just ask.
Don't worry if you're a newby, a senior XDA member, or a Developer. You won't get any flaming or criticizing from me. Asking for help is always welcomed as far as I'm concerned.
The only dumb question is the question that's not asked.

Your post was written on the same day that the Retail unlock was released, about maybe 6 hours earlier, and I'm just noticing this post this morning. First of all, I'm actually now on CM13. Secondly, I've disabled any automatic screen dimming at 5% and 15%. I still get warnings, which I do swipe away. My phone did reboot when it thought it got down to zero, only to find out that I was at 11%. I continued to drain again to 0%, tried to start up, no luck. It was drained. When I was fully charged, I did try deleting batterystats.bin as well, and apparently that did nothing. I'm about to try a mod for battery calibration. The difference between the time of your post and now, is that we're unlocked and rooted, so the mod would not have worked, then, but POSSIBLY, now. I guess I'll be a guinea pig, here.

Hey, I saw that you mentioned in the other thread about someone had posted a beta file. I believe that you are absolutely correct. I'll do my best to dig around and see if I can find that file for us to test. I have tried depleting my battery literally till 0% is true. At that point I checked the mv on the battery and then fully charged using no fast charge cycle and also without turning the device. I have 5 converted DE's and now 6 true DE's. I'm going to test each device at the same time to get an average and also a very accurate account on the validation of the battery stats. Lol at the guinea pig that you mentioned. I've felt that way too. I'll start testing the devices at the same time in the morning about 8:00 am here in Hawaii. I'll report back what my findings are. Post back your findings and I'll do the same. Hopefully we can modify the file properly to meet the requirements for us Zero Lemon users.

I don't know if this is significant or not but the manual states the capacity at 3.85V/3850mV. The Battery Calibration app I tried this morning said my battery was about 4380mV at 100%. I don't think that this was correct on the app's part. I could be wrong. What do you think? BTW, I'm at 58% right now after 9 hours of heavy use, I don't think that's right.

3850 from 4380, that is a good difference. What app did you use? I'll check using another app and we'll compare results. However also thinking about it, if I remember correctly, 3850mV should be correct. I was an original tester for ZeroLemon thats based out of china. They use BaxtelWireless as their Wholesaler / Distributor who is located in lower Texas, and I signed up as a tester / reviewer for them when they first started implementing the battery. BaxtelWireless contacted me later on to test out the battery. The only thing I really dislike, is the fact that it's a tri-cell battery and not single cell. if I remember correctly. They mentioned they were working on the possibility of making a single cell, however I'm positive the price would also increase of they do. After checking I think that 3850mV should be correct, but let me ask someone who works there to get a definite answer. I'll get back with you.

Lookup Battery Calibration on the play store, it's by NeMa. That's what I used.

@47%, 3924mV.

Yup, that's what I'm seeing as well. 3850mV is what they say it should be.

Have a look at this thread. This is the guy I was referring to that was trying to make a mod for this battery. I don't really understand what all he was doing but I don't think he's supported it in almost a year.
http://forum.xda-developers.com/not...nt/reserved-zerolemon-fuel-gauge-fix-t3131705
I feel like I've made some small progress, but honestly, I doubt it. Still seeing the 1% problem. I don't know if that will ever iron itself out or not.
First discharge:
my phone turned off at 0%
I turned it back on, it had 11% left over.
Both occasions, @1%, draining the battery seemed like an eternity.
Did not test battery pull
Tried using BatteryCalibration from the Play Store, it did nothing.
Second Discharge:
Battery drained down to 0% the first time through
Battery Pull did nothing. Turning off and on did nothing. Battery was in fact, dead.
Calibrated using Battery HD Pro. (I think you can do the same calibration with the free version but I'm not sure)
1% battery drain seemed like an eternity, again
I have my phone plugged in, now and I'm going to let it charge for about 21 hours before I turn it on, again. I'll check it when I get home from work in the evening.
Question: Would there be any difference in using the stock charger vs the charger that came with previous Note's with different voltages? I don't know enough about electricity to understand this or not.
thanks to OP for sharing!
i have an original samsung battery charger.
could i use it to charge my zerolemon 18-24hrs for those first 5 charges, while i use my phone with my old original 3220 mAh batteries in the meantime?
After the 5 cycles of 18-24 hrs of charging will I always charge this battery for 18hrs or more and do I always charge it with the fast charging off? After the 5 cycles will my note 4 % sign read true. Any help would be appreciated thanks.

When charging The ZeroLemon battery, you should always charge at the "Lowest Amperage" meaning Fast charge should "always" be turned OFF when charging any ZeroLemon batteries. Leaving the fast charge turned on will charge the battery faster, of course. However, it will "kill" the ZeroLemon battery over time, reducing it's charging life to a mere crappy timespan, and also reducing it's ability to distribute a charge for the device over the original intended time cycle. >This info is straight from ZeroLemon themselves. This is not just my opinion.<I have purchased many batteries from ZeroLemon, on my business account, and this is what they themselves, and their USA distributor instructed us to do for the absolute best performance of their battery.
Another thing to keep in mind is when charging the battery on the slow, non fast charge cycle. To always charge with the phone off. No, this isn't so the phone can charge the battery faster. It's so the battery will get the "Full Charge" it's intended to receive. What do I mean, you might ask? When charging the OEM factory battery, the software is programmed to look at the /data/system/batterystats.bin file to determine calculative information and statistical information about the battery itself. This information guides the system on where the battery is at its charge cycle along with various other related task.
Zerolemon clearly states: "Shut down, plug in the power supply and charge until full. (Preferably continuously charge overnight to ensure maximum power. Remember to not switch the phone on, until battery is fully charged.)"
So how do you know if this monster of a battery is fully charged? Well, there's a couple ways. You can look at the whitepapers or on the battery and get the full amperage/voltage cycle information, or you can simply use some simple math to determine what amount charge you're charging at and then determine the amount of hours it will take for a complete full charge.
Now, I can make this a little easy for you and help you out with this. If the battery is brand new, meaning it just literally arrived and you just opened it from the box. Charge for afull 12-18 hoursfor the first charge. Do this with the phone off. When you hit that time mark, you can turn the phone on for use. Now keep in mind I said 18-24 hours for the first charge. Since Zerolemon sends out the battery with some bit of a charge on it, it's impossible to get the exact amount of charge for sure. So when in doubt, charge it fully out. That means 18-24 hours. Yes, yes, that's one hell of a long charge. But let me tell you. I use my phone all day. Full screen brightness, everything turned on, Bluetooth, Wi-Fi, etc. Watch videos, games, hit the forums, obviously . And I always get 3 to 4 days of use. That's right baby. 3 to 4 days of use. The secret is the long slow charge. These batteries are not single cell, they are a tricell makeup. The slower and longer the charge, the longer the battery will last.
Now back to the charging cyle info. You've already charged the phone up completely for the first time. Now use that sucka! And I mean use it till it completely gets to 5% and the system forces you that crappy power save mode where it dims the display etc. Power the phone off. Remove just enough of the rubber TPU case to lift up the battery from the contacts. Count to 3, then replace the battery, TPU, etc. Don't be shocked when you power it back on and you've got 80% full battery again. Remember this is a tricell, so it doesn't report correctly what the exact amperage/voltage is to the android system. Now continue to use the battery and repeat until the battery is at 5% all the time when reinserting it again.
Now, the step above is where everyone messes up and just depletes the battery to 5% only "one time" and then goes to charge the battery again. Don't do it! You're cheating yourself out of precious battery life.Follow the above cycle exactly as I said and you'll be thanking me later, that I promise. If you've already had the battery for a while and been charging it incorrectly, don't worry. Deplete the battery as outlined above, then charge for 18-24 hours, remove battery, insert battery, repeat till stays continually at 5% then recharge.
OK. Now let's move on. Once you continually hit that 5%, Start the charge cycle over again by charging the phone with Fast Charge turned OFF, the full 18-24 hours. Then repeat the steps outlined above again.
>>IT'S EXTREMELY IMPERATIVE THAT YOU DO THIS 5 CYCLES.<< (Sorry for the caps, but really need to stress the importance of this.)
Once you have completed the five cycles, you're on your way to always leaving that blasted charger at home, and never again being thought of as a "Wall Hugger" if you've seen the commercials .
=> Don’t stop charging even it shows 100% charged. And if you're seeing this 100%, then you didn't turn off the phone during the charge as indicated above, lol. A true "Full Charge" is only performed when the battery has been charged for 18-24 hours.
Charging Scenario
When you are doing the first "5 Full charge and Deplete cycles", the phone must be powered "off" while charging. This is due to the android operating system and the Note 4 thinking the phone is fully charged when it reaches 100% even though in reality it's truly not. The Zerolemon battery may only be in reality at 30%, 40%, 50%, etc. Remember, the device believes it has the OEM factory battery in it, and not the massive Zerolemon battery. Unfortunately if you're not rooted with a Developers Edition Note 4, it cannot differentiate between the two batteries. So for the first 5 full charges, (this is referred to as the conditioning of the battery,) turn the phone off when charging.
Now after the 5 cycles have been completed, and the conditioning has been done. You can charge the battery with the phone on. However its important to remember that:
1. When your little battery icon shows full, or if you have the battery % on, & it shows 100%, don't stop charging. It thinks you have the Factory OEM battery in place. To ensure that you have a "True Full Charge" the total noninterrupted charge time must be no shorter than 18 hours and no more than 24, if the battery is truly fully depleted.
2. Properly charging a battery of this size works as follows. The battery has been charged 18-24 hours and is fully charged. You use the device depleting the battery over a period of a few days, while in the process, when it hits 5% you remove the battery and then reinsert as mentioned earlier, then continue to use the device till the battery is actually fully depleted. This means the phone won't power on anymore.
Now at this point, you'd start the charging process again, for 18-24 hours.
Do not charge at every day or every night just because the battery is a little low. (Because almost devices are powerful hungry and batteries depletion is very quick, people are in a habit of just throwing it on charge whenever and however.) Only charge when the device is completely and fully powerless.
Routinely charging the Zerolemon battery in different increments will cause a severe and nonreversible battery retention that will prevent the battery from not only being able to give full use, but prevent it from being able to be fully charged anymore.
TIPS:
Zerolemon batteries for the Note 4 are notorious for prematurely shutting down the phone by means of loss of power if the phone is dropped or in some cases even bumped. The reason this occurs is because their is a small discrepancy in the exact battery size where the contacts meet the pins on the phone. In layman's terms, the Zerolemon battery is just a bit short. No, it's not gonna fall out of the back of the TPU case or anything like that. However, if you drop the phone, or even in some reported cases, bump the phone, the Zerolemons battery loses connection with the gold contacts from the device from within the battery compartment.
Reports have been made to Zerolemon concerning the issue, however Zerolemon has failed still yet, to resolve the problem accordingly. Most likely because just a simple change of plan, would literally open the door for thousands of recalls, refunds, etc, not to mention cost thousands of dollars to remap the sizing and make the correction to future batteries.
Well with this said, all is not lost. I've found, if you remove the TPU case, leaving the battery in place, you can insert a small shim of paper at the proper place, and this will totally resolve and eliminate the problem 100%.
You can use paper, plastic, Thin gasket material etc. Whichever is most convenient for you at the time.
The proper placing of the paper is crucial. Because you don't want to cover up the path to the speaker phone compartment any more than it already is.
Here's the easiest way to fix it.
Power off your phone. Now remove the TPU case and lay the phone carefully screen down so the battery compartment is facing upwards. Position the phone where the bottom of the battery compartment is closest to you, and the camera is furthest from you. Now remove the battery. On the bottom right side of the battery compartment you will want to insert your paper, plastic, "fix" etc to the bottom right side of the compartment. The paper thickness I'd recommend would be the thickness of a regular matchbook cover, or about 2 sheets of construction paper. The dimensions I used was about 1/8 inch tall, by 1 inch long. Don't lay the paper flat inside the battery compartment, doing so will cause the battery to be a little "thicker" and not make connection. You will want to "Stand Up" the little piece if paper, or if you're feeling savy enough, permanently afix the paper to the housing. Now when you go to reinsert your Zerolemons battery, you'll notice that it not only actually first a little tighter and snugger, like it should have been on day 1. But it also doesn't let the battery wiggle a little like before. Replace your TPU case, and power on your phone.
I'll upload some pics for you to show you how I did mine. If you got any questions on any of this, just ask.
Don't worry if you're a newby, a senior XDA member, or a Developer. You won't get any flaming or criticizing from me. Asking for help is always welcomed as far as I'm concerned.
The only dumb question is the question that's not asked.

Definitely don't use the Samsung Adaptive Fast Charging adapter if you turn off the phone. Find another charger that is 2.0, otherwise, even if you have fast charging off in the settings...it will fast charge when the phone is charging when it's off and it will say it when you see the charging going on. Read that somewhere else on this forum and he was absolutely correct!
Correct me if I'm wrong here, but if your phone believes the battery is at 100% doesn't it stop charging the battery and only draws a trickle charge? what good is leaving your phone plugged in when your phone itself will not charge it fully? there must be a way we can physically charge the battery itself. I'm about to take apart an old charger and alligator it into a regulated power supply. someone stop me if they think that's a bad idea.
How can you turn off your phone and not use it for 12hr+? kind of ridiculous if your cell phone is your main source of contact.....
Hi, I've had my Zerolemon 10000 mAh Battery & case for just over a year. Using it in a Note 4. Not being tech savvy I initially charged it to 100%. and I have done the plug it in every night thing & had it on fast charge. Now, I have a question, since I have done all these things wrong on this battery the battery is running out of charge within 3 to 4 hours at least. Can I reprogram this battery or have I ruined it?
