As it has been previously said and thoroughly tested, this battery is "STILL" & will "REMAIN" a "TRI-CELL BATTERY." Because of the characteristics of the battery, it will never read the correct percentages on the Samsung Note 4.

If you are getting good results with the battery, and are happy with doing the unnecessary battery pulls just to get the approximated correct values pertaining to the remaining estimated time, then that's great. However it still is, and will always be, a "TRI-CELL" Battery that will not read correctly.

The craftsmanship of the product is and never was designed to be that of a high caliber, accurate, and long lasting product. It's targeted for simply supplying a large amount current for the Note 4 regardless of what the percentage values read.

Not fully depleting the battery will eventually lead to a memory effect regardless of what links you supply. Fir every link there is a counter link saying just the opposite. NOBODY wants to sit at 5% for three days with a dimmed screen and all of the Note 4's battery saving options enabled with no way to disengage. LOL. ?

We are glad that you support the product, however your comment about "So will millions of others" is loosely conveyed with no backing of its own.

Lastly, your 'name calling' and 'verbal tone' you portray only further points out those actions of a child, and are not needed nor wanted here on the XDA website.

Runnalong and have a good day! LoL

I am new to this thread. if i am reading it right, the battery will loose battery life faster than normal because the galaxy note 4 has issues with reading tri-cell batteries. so because of that, the phone will still last for many days, just the percentage would be incorrect?
[Galaxy Note 4 Accessories] TheLoneWolf20:
All I have to say is that I rather have the company keep making the batteries regardless of the problem. At least you have a extended battery. But I wouldn't mind spending the extra $20 to $40 for a Single cell battery that reads properly. Better yet, SAMSUNG should make different battery variants. One 3,220 mAh, another 6,000 mAh, and one 10,000mAh. Also I really don't think the problem lies in the OS but rather the Fuel gauge chip. The Maxim 77843 fuel gauge chip isn't capable of reading multi cellular batteries. To be honest, the chip only reads current and voltage levels. It has no storage of the battery capacity like other fuel gauge battery chips. But it has a special algorithm that comes up with the battery remaining capacity. Now, there are mods to where you can make the battery say its at 100% for one to 2 days and then drop down when it's on the last day of usage.

The note 3 uses a different fuel gauge chip which is the reason why it showed better battery stats.

It is how the cells are tired together. So 3 cells discharging at different rate. I thru mine out. Gave up on it. Bought 3 hyperion 8000 and no issues at all.
[Galaxy Note 4 Accessories] TheLoneWolf20:
Yep. But ZeroLemon and this other Company needs to get on the ball and make a SINGLE CELLED BATTERY. Get with a battery making company and make it happen.
[Galaxy Note 4 Accessories] BigMosley:
I just came from the Note 3 with ZL battery and it was amazing, hands down. I would get 3-4 days on 1 charge, couldn't beat it. I always swore I would never buy another phone that ZL doesn't make a battery for....I was wrong. It is what it is, if you have the patience to deal with pulling the battery every day then go for it. Definitely not for me. Create a single cell battery thats 10,000 then I'll consider buying another. Until then, farewell my old love.....
[Galaxy Note 4 Accessories] TheLoneWolf20:
Yeah they took the easy way out and gave us A Lemon.
[Galaxy Note 4 Accessories] xeonbuilder:
For the most part yes. The main problem I found was that the battery gets down to 1% and the phone dims out because it thinks it really is at 1% when in actuality the phone usually had about 50% left. You would then pull the battery and put it back in and there you have the missing 50%. If you do the pull you can get 3-4 days with no problem before it dies.

Quality is not the issue here. Its just the fact that I dont feel like pulling the dam battery every time it gets to the imaginary 1%.
[Galaxy Note 4 Accessories] TheLoneWolf20:
It seems like when you don't touch the phone, it calculates well, but when you start using it and tapping the screen a lot it drops fast.
[Galaxy Note 4 Accessories] jacob808:
It sounds bad but it's not that bad. I myself wasn't about to purchase because what you wrote was my understanding, but I purchased it, and at first the negative criticism painted my perception of the battery as awful but I stuck with it and now I never want to part from this battery, just because it's perfect for the Gear VR. Yes you need to take off the case to insert it into the head set but that just gives you the perfect excuse to do a battery pull and increase the percentage again. Awesome.

Also the depletion is not that fast it'll take a while to even get to 80 percent. I've been on my phone for 3 hours now and I'm still at 91 percent, and thats not even doing a battery pull. If I did it'll probably go back up to 100 haha

On note 3 depends on which battery u got. They had single cell and tricell. Tri had same issues.

[Galaxy Note 4 Accessories] BigMosley:
I had the very first model which came out late November 2013 and got a 2nd one around mid 2014 and both were excellent. Completely different then the N4, which is a shame.
[Galaxy Note 4 Accessories] BACARDILIMON:
U had them when they was good from my understanding. Before it went to tricell. I say why mess with it when single cell works nice. Lol

[Galaxy Note 4 Accessories] jayden485:
So I have bought this and it arrived, I noticed it was depleting fast, and then I read this thread. Now I understand why. I don't mind pulling the battery for it to reset, the only thing I'm confused about now, is when you leave it plugged in, does it actually charge the battery, even though it says fully charged?
[Galaxy Note 4 Accessories] JOSHSKORN:
If I understand correctly, the Note 4 "assumes" you have your stock battery inserted until you can calibrate it correctly. Easier said than done, particularly on the Note 4. As far as I know, you need root access on your phone for apps that calibrate to function correctly. Unfortunately, this is a problem for AT&T and Verizon users because of the locked bootloader/write protection. Also, as far as I know, the ZL is a tricell battery and the stock battery is a single cell, and I THINK that also plays a role somehow...exactly how, I'm not sure.

That said, the phone still thinks you're on a 3220 mAh battery, so if your ZL is completely drained and is at least 1/3 charged, the phone THINKS the battery is fully charged, since it's just over 3x the size of the stock battery....or something like that. I sent my ZL back for a warranty replacement and still haven't received a new one. I need to contact them about that. I honestly haven't timed charging time on the stock battery with Fast Charging off so I can't say for certain that one charging time is 3x the other.. If you download apps that tell you the mAh of your battery, they'll more than likely tell you 3220 mAh, no matter what size extended battery you insert. I've tried the stock, ZL and also the Hyperion with the exact same result.

Because of the calibration issue, or lack of, my ZL battery would hang on at 1% for 12 hours. By that logic, the battery should last a month and a half if each percent took 12 hours to drain. This is DEFINITELY NOT THE CASE.

See what happens when you assume?

If you have a Retail Verizon or AT&T Note 4, I highly advise you to just return the battery while you still can, and just purchase a second stock battery. While both of those models have "temp root", you are also instructed to turn your phone off while charging. Due to write protection on those models, you lose root when you reboot, therefore more than likely, any calibration tweaks will be lost as well. There is work being done in terms of people trying to unlock the bootloader and deal away with the write-protection, but I wouldn't count on it happening anytime within your return warranty.

These are just opinions, of course. Have another person or two chime in before you make up your mind.
[Galaxy Note 4 Accessories] TheLoneWolf20:
I guess they did it because they wanted a 10,000 mAH battery and not a 8,000 or 9,000 mAH one xD

---------- Post added at 09:27 AM ---------- Previous post was at 09:25 AM ----------

I wish there was a way that simulated pulling the battery by periodically resetting the chip which resets the battery level. If it was that simple then you can create a init.d script to do it every 5-10 minutes. On older phones you could do this, but sadly not on the Note 4. I wish Samsung Make the same size battery like on the Note 3. But if you guys want me to, I can make a Custom Kernel (For those that use BIOSHOCK's Kernel) where the battery percentage doesn't go to 1% but stops at 6% which lets you use the Camera and doesn't dim the screen.
[Galaxy Note 4 Accessories] jayden485:
I have a rooted Note 4, how exactly do you calibrate it then?
[Galaxy Note 4 Accessories] TheLoneWolf20:
Calibration is not possible because Samsung's fuel gauge chip and drivers use a different and secret algorithm method on retrieving battery SOC or State of Charge. It can be done with other phones but not with this phone or any phone with a Max77843 Fuel Gauge chip. The ONLY way you can fix it is have someone create a separate app and do some Kernel file mods that accurately calculates the 10,000 mAH battery usage and ONLY gets the percentage from that App and not the actual Fuel gauge chip. It has been done before to a Sony phone. http://xdaforums.com/showthread.php?t=1312398

[Galaxy Note 4 Accessories] Eldartho:
Here's an idea....

Instead of just trolling and complaining about the size of the thing maybe understand that there are people you actually have a use case for this behemoth of a battery.... Drive a truck for a living and just try making it thru a day with Google maps going and Spotify streaming over Bluetooth! Not gonna happen! This will be my 4th zl battery after the note 2, note 3,and g3 I've never had a problem with them and I swear by them and won't by a phone unless they make a battery for it.... Mine has been on pre-order for what seems like forever and should hopefully come next week..... God I cant wait
[Galaxy Note 4 Accessories] Cloaker:
How are you guys calibrating this battery? Mine decreases quickly from 100 to 800(1 hour ish), then it gets to about 5 % and stays there for awhile. When it hits 1%, I can get several hours of heavy use out of it.

I've tried charging it for 12 hours. I've tried charging it at 1%. I've tried letting it die.

Any ideas?

Thanks!
[Galaxy Note 4 Accessories] Uncle Glen:
I did notice something...

If you turn off the phone, take out the battery then re-install it, it seems to recalibrate its self. For example, after doing a full charge and using my phone through out the day by battery showed 69%. I turned it off, took battery out and put it back in. when i turn my phone back on it is at 89%.
[Galaxy Note 4 Accessories] Cloaker:
I've noticed that too, but how do we get it to do that on its own? Lol
[Galaxy Note 4 Accessories] easycure1974:
But when sitting in a truck whole day a car charger must be pretty easy to use? :) I have a hard time deciding if to order it or not but 10000 mah is pretty tempting when going for a hike in the woods

Unless said truck doesn't have a working cigarette lighter.... And this 10,000mah beast plus my 32,000mah portable battery pack is for the doomsday scenario of me being stuck on the side of the road in the middle of nowhere for hours on end... It's happened before and it'll happen again

[Galaxy Note 4 Accessories] artofwar:
I am still waiting for my zerolemon... but got this email from them in regards to the fast charging/battery level:

Greetings from

Bastex Wireless!

In the spirit

of open and honest frontline Customer Service, we would like to share with

you some information about your recent Note 4 purchase.

It has come to

our attention that Fast Charge, one of the built-in features of the Samsung

Galaxy Note 4 phone, works exactly as designed by the phone

manufacturer.

This is an

awesome thing, as it will also work to Samsung specs with your ZeroLemon

10000 mAh battery!

Unfortunately,

a Samsung battery is 3220 mAh, and therefore Fast Charge will stop charging

your ZL battery when it’s less than a third full.

That’s

okay, though! You can take advantage of Fast Charge up until the

initial disconnect, disengage Fast Charge, and then finish charging your ZL

battery through normal charging. With a 2.0 Amp charger, it should

take less than four hours to fully charge after you’ve hit the end of

the Fast Charge Window.

For help in

toggling Fast Charge and fully charging your ZeroLemon battery, please see

the following link:

http://zerolemon.com/core/uploads/2013/11/total.jpg

For now,

please remember that the ZeroLemon company and we at Bastex Wireless fully

support your purchase with both the 30 day ‘Zero Hassle’ refund

policy and 180 day full replacement warranty. We hope to give you the

best possible customer service experience, and will be happy to do

everything in our power to ensure your satisfaction!

Happy

Holidays!

Drain it down to DEAD and see how long it holds onto 1%. My guess is, it SHOULD be equal to 2%-5% since the phone power saves starting at 5%. Your findings SHOULD tell you if your battery is correctly calibrated or not.

Every battery I've got from Zerolemon was a Lemon, lol. It's almost kinda like they should have renamed their product line. Hahaha.

They should be called EveryLemon, cause that's what they are. Their batteries aren't worth postage. I've been using the Hyperion 8000 and I get 3 & 1/2 days of full use screen at 75% normal use. Or 2 & 1/2 days with screen at 100%, 2 minute time out, heavy use, WiFi on, Bluetooth on, everything on. If you aren't sure about Hyperion, you should try it. You get an excellent product plus the sound is routed out the correct hole so it's still loud and crisp. The color tpu cases are well made. They BATTERY READING is ALWAYS CORRECT, (all caps for effect hahaha) and simply put it stomps the sh*t out of any zerolemon battery hands down. I know. I'm a certified tester, developer, etc, etc, etc, lol.

Really the Hyperion is what the Note 4 should have come with stock.

Well at least I got something out of this experience. Learning how to make and compile my own kernels so a positive for a negative.
[Galaxy Note 4 Accessories] TheLoneWolf20:
Even though there isn't really a fix, I am going to try one more thing on that old App considering I have the Kernel Source code, I am going to try and break the Fuel Gauge chip on the kernel level keeping it from polling to the power_supply/ capacity files which the android system accesses to get the battery percentage; which should allow any value I set to stick. Currently, when I echo a command in Shell, the value I set the capacity to does go through but doesn't stick due to the polling time.
[Galaxy Note 4 Accessories] DavidCDM 2.21:
From you point, MYDE tricell battery is better than ZL, because they use simple TPU case and make battery easy pulling?

---------- Post added at 03:29 PM ---------- Previous post was at 03:18 PM ----------

I will wait for you App, then go to buy one MYDE battery because if your App not work, I can easy remove the battery and put it back in. Lol
[Galaxy Note 4 Accessories] TheLoneWolf20:
The app should work as it is acting like a whole another Fuel Gauge Chip that calculates the SOC by the voltages of the components that are being used. The App lets you set the mAH capacity and then it also lets you set the mAH usage of each component rather its LCD screen on, LCD Screen on Minimum brightness, or High Brightness CPU active or idle + the different Clock Speeds etc. Most of this stuff is located in Power_Profiles.xml
[Galaxy Note 4 Accessories] TheLoneWolf20:
I actually got the app to show successful and work. I broke one part of the fuel gauge driver (it's not broken really, it's just a custom kernel that stops polling of the chip values. Flashing another kernel file will fix it). I still need to dig deeper to turn off the capacity file. Right now I am running a while true; do loop, which is forcing the app software values to stick to the capacity file which isn't really good as it constantly uses the CPU. But I am only doing it to see if I can get it working.
[Galaxy Note 4 Accessories] DavidCDM 2.21:
wow, you are really geek.:good: Awosome work. Not like other guy, "tested that months ago with 3 zero lemons before they went back as defective" lmao.
[Galaxy Note 4 Accessories] wub02:
I noted that you also find that when phone is at low current state, battery calculation is more accurate then high current state, do you know if there are different calculation routine for high and low current? I ask this because I'm a average to low user and my ZL battery is calibrated and read thru this thread that ppl having problem to calibrate are high power user.
[Galaxy Note 4 Accessories] TheLoneWolf20:
I think this is true. You have to know that this ZeroLemon Battery is a TRI-Cell battery meaning the're 3 different batteries put together into one. Each battery reads an individual current and voltage level. When you put a high draw load on the device, the voltage level will drop and then rise up again when the heavy load stops which leads to a incorrect read. On a single cell battery, since the phone is getting the power from one cell, the battery will have a more stable voltage and current reading with or without a high draw load. The Fuel Gauge Chips aren't smart enough on the Note 4 to see this and correct itself.
[Galaxy Note 4 Accessories] wub02:
Well, I did mention before cells connected in parallel treat as single cell but total current is the sum of the cells Ct = C1+C2+. . . Cn . There is no way to make such shape like ZL out of one cell (as far as I know there are only two shapes, cylinder and rectangular for any consumer product) , so any odd shape have to put together like LEGO, to get the current or voltage requirement, even those "double" capacity extended batteries are made out of 2 cell (peel one open and you will see), of cause for different reason.

Anyway, I was fallow your step look into the source code but didn't go too far but I did see some interesting thing, in the max77843_fuelgauge.h there is section:

/* FullCap learning setting */

#define VFFULLCAP_CHECK_INTERVAL	300 /* sec */

/* soc should be 0.1% unit */

#define VFSOC_FOR_FULLCAP_LEARNING	950

#define LOW_CURRENT_FOR_FULLCAP_LEARNING	20

#define HIGH_CURRENT_FOR_FULLCAP_LEARNING	120

#define LOW_AVGCURRENT_FOR_FULLCAP_LEARNING	20

#define HIGH_AVGCURRENT_FOR_FULLCAP_LEARNING	100

These looks like fuel gauge driver will calculate new capacity (from old value)

Also in max77843_fuelgauge.c, routine like:

static int max77843_fg_read_fullcap

static void max77843_fg_get_scaled_capacity

static void max77843_fg_get_atomic_capacity

static int max77843_fg_calculate_dynamic_scale

And last in N910T/arch/arm/configs/apq8084_sec_trlte_eur_defconfig :

CONFIG_FUELGAUGE_MAX77843=y

CONFIG_FUELGAUGE_MAX77843_COULOMB_COUNTING=y

CONFIG_CHARGER_MAX77843=y

CONFIG_SAMSUNG_LPM_MODE=y

CONFIG_BATTERY_SAMSUNG=y

CONFIG_BATTERY_SAMSUNG_DATA_FILE="tr_battery_data.h"

CONFIG_AFC_CHARGER_MODE=y

CONFIG_BATTERY_SWELLING=y

Could tr_battery_data.h is the battery define file?

I'm no programmer so all this could be way wrong :crying:, I hope you still looking for the fix.

At less mine is all good, and I even ordered MYRE because I like that case:silly:
