[Galaxy Note 4 Accessories] BigMosley:
I must say I am pretty disappointed in the Note 4 battery so far. I pulled it off the charger this morning from a straight 8+ hour charge from 5% battery life and it's already on 40% after 14 hours of minimal use & just over 4 hours screen on time. The Note 3 battery would still be on probably 80% right now (and the battery was well over a year old). ? I am however using the Note 3 charger instead of the actual Note 4 charger, do you think possibly the phone wasn't 100% charged after 8+ hours which is why it dropped so quick? Does it matter which charger your using since we can't use fast charging anyway?
[Galaxy Note 4 Accessories] TheLoneWolf20:
It doesn't really matter what charger you use To be honest. Although, I would use a 2 amp charger or it will take you forever with a 1 amp of .5 amp charger. Really, when you use a extended battery you are supposed to turn off fast charging. But fast charging only works with the stock Samsung charger so I don't think it matters when you use another charger since the phone communicates with the Charger IC chip.
[Galaxy Note 4 Accessories] BigMosley:
Alright, well since I've only used the battery for a week now I'm going to keep an eye on the battery cycles and if they don't improve within the warranty period I might be contacting ZL for a replacement as well like many others on here have. This is the first problem I have ever had with the company.
[Galaxy Note 4 Accessories] TheLoneWolf20:
I'm finally done with finals so I should be able to focus more on this problem other than work. It's been a real pressure cooker these past few weeks so thanks for being patient lol. In other news, I found the string to change the battery percentage so I can attempt to get some sort of calibration but I am still testing it. If there was a way to have a multiplier on the current percentage, it would be good you know like for every 5-9% abnormal drop, drop 1%. But just having the ability to change the battery values means there is a chance for a fix. lol 700+% battery life xD But when I find a potential kernel patch and do through testing, I will for sure put up a ALPHA version for testing.
[Galaxy Note 4 Accessories] wub02:
Have you try just change the default battery value to see if that will do something for the gauge read out in the header file default_battery_data.h?

.Capacity = 0x187E, <---original

to

.Capacity = 0x4E1E, <---9999mAh

I know there are more then just change a value to solve problem as found many routines in max77843_fuelgauge.c and sec_fuelgauge.c that alter the numbers.
[Galaxy Note 4 Accessories] jacob808:
external power banks or battery packs won't show a correct percentage of power left that's why they use bars instead.

I believe that the zero lemon extended battery is pretty much like an external battery power bank such as the Rav 10500 mAh and so won't be able to give an accurate percentage reading.

The solution would be to just turn off the percentage reading and use the battery icon as a gauge.
[Galaxy Note 4 Accessories] TheLoneWolf20:
Thats not really a solution because the percentage reading is tied to the battery icon.

---------- Post added at 10:35 PM ---------- Previous post was at 10:32 PM ----------

I tried the default_battery_data.h and it didn't do anything. When you compile the kernel the file doesn't get added to the compile list. The kernel only loads sec_battery, sec_board-8084, max77843-fuelgauge, and max77843_charger. Now I am modifying values in the max77843_fuelgauge.c area and they do change the battery level but its the fact of getting them properly set and sometimes the percentage bobs up and down.
[Galaxy Note 4 Accessories] BigMosley:
I gave up and I am returning the battery for a refund. I don't have time to play games with this dang battery. I Bought a Otterbox defender and may just purchase a additional battery, thankfully our phones have the snazzy fast charge option so if and when I get in a dead battery time crunch it won't be dead long. There's always a silver lining my friends!
[Galaxy Note 4 Accessories] TheLoneWolf20:
Yeah I am getting to that point also. I still want to try out that Hyperion battery.
[Galaxy Note 4 Accessories] BigMosley:
My brand new defenders silicone volume up button is crooked and you have to literally mash it down to work and the built in screen protector is about 1/8" raised off the screen and is hard to type, let me tell you I can't win lol
[Galaxy Note 4 Accessories] jacob808:
Well if it takes away the annoyance and gives people a sense of peace that "it is what it is", and that it lessens the anxiety of wanting a correct percentage reading from such a huge capacity powerbank.

I've had many external batteries/power banks that were 10,000 MAH from the aforementioned RAV 10,000 (sorry I put 10,500 on my previous comment) to Li-on battery packs for my electric bicycle kits and all of them did not display any sort of precise percentage drainage meter, but instead used a 4 bar guage to let people know an estimate of how much power the bank had left to supply.

I think that's why the ZeroLemon battery at it's MAH capacity is not meant to give you precise readings but more a "guesstimate" of how much power is left in a battery that would usually last 2-3 days.

Again just take off the incorrect percentage reading and go with the battery icon, and yes I know it's tied to the percentage reading but you'll have to do a battery pull anyway, but this way you won't be erked by the inaccurate percentage displayed. haha
[Galaxy Note 4 Accessories] BigMosley:
Look, I was just driving in a unfamiliar location with navigation running and the battery fell below 5% and the screen went so dim I couldn't even see. I had to pull over and pull the battery for a few mins and it shot back up to 40%. This is unacceptable and quite ridiculous. The battery percentage isn't the entire problem, the fact this phone cannot read the larger battery capacity is. Oh well life goes on.
[Galaxy Note 4 Accessories] jacob808:
Also, the ZeroLemon battery works really well with the Gear VR. I almost regretted getting the ZL battery thinking it was useless because I wouldn't be able to use it with the Gear VR because of the case, but guess what it works!

You will have to take the case off, and I know you're wondering "won't the battery fall out then?" actually no because the Gear VR lens cover acts as the PERFECT battery cover as it snugly accomodates the ZL battery and holds it in place while you put on the VR headset.

I've played many hours and looked around constantly up down all around and the Gear VR lens cover holds strong. It's as if that was the whole purpose of the lens cover, to act as a battery cover for the ZEROLEMON. So yeah all those battery pulls you'll be doing to reset the percentage won't be in vain at all because you'll have to remove the case anyway to put the Note 4 into the Gear Vr. Game all you want and still have a ton of battery life...
[Galaxy Note 4 Accessories] TheLoneWolf20:
The thing is that the phone reads the battery; if it didn't it wouldn't let you charge it or see the battery voltages. But it isn't smart enough to calibrate properly and detect the cells.
[Galaxy Note 4 Accessories] unibomber:
I've done 2 charges of the hyperion and it last about as long as a regular battery. I have to give it a few more charges to assess it's use. U keep going back to my zl
[Galaxy Note 4 Accessories] TheLoneWolf20:
So the Hyperion isn't really a extended battery.
[Galaxy Note 4 Accessories] unibomber:
Gotta give it a few more charges to see if it gets there. People have had good success with the hyperion.
[Galaxy Note 4 Accessories] BACARDILIMON:
Great results with that battery. But honestly since on lollipop no need for extended anymore unless I working 3 days straight.
[Galaxy Note 4 Accessories] TheLoneWolf20:
Still working in code and trying to come up with a accurate Battery Stats Multiplier so for every 2 or 4% increase, it increases the real capacity of the battery by 1% which will give a more realistic capacity. Of course, this would be only calibrated to the ZL 10,000mAH battery, so you would have to change kernels if you were to use the stock battery again. Is it a fix? Not quite, I wouldn't call it that right now since I am still testing and implementing this. But even if I get the 1% issue down to 6-12 Hours, its still a Improvement.
[Galaxy Note 4 Accessories] TheLoneWolf20:
I am still working in the Max77843_fuelgauge.c file and making changes to values and I was able to obtain better battery statistics. I am still making mini tweaks here and there, but it is much better than before and I have used this phone a lot today considering that I was on a road trip. I have the Modified Kernel of this mod in Alpha if anyone still wants to try it that is on a T-Mobile Variant that has and still uses the ZeroLemon 10,000mAH Battery. Of course the Kernel Source is from BioShock so if you can run stock TW BioShock Lollipop, then this mod should work fine.
[Galaxy Note 4 Accessories] unibomber:
I will!
[Galaxy Note 4 Accessories] TheLoneWolf20:
Seems like the phone always idles well but when it is being put to use, it goes cray cray. Nevertheless, I just want to see what it does when it gets down to 1%.
[Galaxy Note 4 Accessories] BigMosley:
My hats off to you people who put up with this battery, I hope this battery mod works for you.
[Galaxy Note 4 Accessories] JOSHSKORN:
It looks like a non permanent root method has been released. Has anyone seen it? I wonder if it'll have any affect on apps thst attempt to condition the ZL battery.
[Galaxy Note 4 Accessories] TheLoneWolf20:
lol yeah it is a issue, but It gives me something to do over the summer lol.
[Galaxy Note 4 Accessories] BigMosley:
I hear ya and I thank you for your work and dedication. But I can think of something else I'd rather do over the summer if you get my drift ?
[Galaxy Note 4 Accessories] TheLoneWolf20:
lol yeah but even that gets boring. I have all summer to do that xD

---------- Post added at 01:22 AM ---------- Previous post was at 01:21 AM ----------

Post it up and lets take a look.
[Galaxy Note 4 Accessories] JOSHSKORN:
It's still kinda experimental I think and does not stick after a reboot, due to write protections from the bootloader It ONLY works in KitKat 4.4.4, NOT Lolipop 5.0.1. That's all I know about this. Don't shoot the messenger. You CAN downgrade to KitKat using a program called Odin from what I've heard. Don't know how to find that topic, but search it out.

[Galaxy Note 4 Accessories] TheLoneWolf20:
Oh I was just wondering. I have a T-Mobile version so those are automatically baseband unlocked. But to flash kernels, I think you have to be baseband unlocked.
[Galaxy Note 4 Accessories] JOSHSKORN:
OK so since you're on Tmobile, are you already rooted? Have you tried apps that calibrate your battery? I'm on Verizon, have a locked bootloader and have yet to see root on my phone, although like I just said, a root was literally JUST released roughly 12 hours ago, but it isn't permanent.
[Galaxy Note 4 Accessories] TheLoneWolf20:
lol yes I am rooted and I am running custom firmware. I have tried all the apps and methods out there and none of them work. (Which is why and how I am able to create and test a fix)
[Galaxy Note 4 Accessories] unibomber:
You hit 1% yet lol
[Galaxy Note 4 Accessories] TheLoneWolf20:
LOL, I did and it didn't take as long as it use to before the mod. I am trying to fine tune it so that it can stay at 100% a little longer, but as it goes down, it will give you a idea of how much time you have left.
[Galaxy Note 4 Accessories] TheLoneWolf20:
I did a 100% tuning and now I am doing a 1% to 0% tuning. Its taking a while for me to come up with a fix because of course it takes a while to go through 10,000 mAH xD. As well as, in the Max77843 driver, there are 2 places in the code where it handles the drain percentage and the charging percentage; and they have to be calibrated equally or they won't work well or will be off balanced when you go to charge it up again. Anyway, if all goes well, I should have something by the end of this Month. (Hopefully before the end of it)

It looks like I have the "How long it takes the 10,000 mAH battery to fully charge down from zero". At roughly 8 to 10 Hours with a 2.1 Amp Charger.
[Galaxy Note 4 Accessories] TheLoneWolf20:
Yeah I did more calculations and I think 13 hours is more appropriate to charge the battery from 0% - 100% while using a 2.1 Amp Charger with the screen on or in other words, still using the phone while plugged in and about 8-10 Hours in Standby.
[Galaxy Note 4 Accessories] JOSHSKORN:
and what if we were using the stock charger with Fast Charging turned off?
[Galaxy Note 4 Accessories] TheLoneWolf20:
It's the same because the stock charger is a 2.1 amp charger with fast charging off.
[Galaxy Note 4 Accessories] hobojo:
I've read through this thread and had some questions.

The report with some users getting less battery time after the initial 12 hour charge is probably due to not charging at around 12-13 hours when the battery runs down?

Is the case any good in terms of protection?

If I want to get more battery time, accurate battery reading, and good phone protection, would this case + Hyperion battery be the best combo?
[Galaxy Note 4 Accessories] TheLoneWolf20:
First question, yes that is possible. I don't think the cells in the battery are dying out.

Second Question, the case is fairly good. I accidentally dropped my phone on a hard tile surface from waist high and it bounced and survived. Of course, I also had a 9H Tempered Glass protector on the phone also.

Third Question, To be honest, I am not sure about the Hyperion battery. I have heard that it is a more accurate battery. Getting more time, I am not sure of and the case on the Battery isn't so robust like the ZL case. Although, it isn't as thick also. It all goes down to personal preference. I like the ZL case. But one day I will order the Hyperion battery and try it out.
[Galaxy Note 4 Accessories] unibomber:
I use the hyperion in the zl case too. Nice combo
[Galaxy Note 4 Accessories] hobojo:
Thanks for the answers

Which glass protector did you get?
[Galaxy Note 4 Accessories] TheLoneWolf20:
I used a Cellet 9H Tempered glass protector. Like most of the Note 4 9H tempered glass protectors, they have the ghosting issue where the adhesive doesn't stick to the screens on the edges because of the way the Note 4 screen curves. I just got use to it. I like how it feels when using it.
[Galaxy Note 4 Accessories] unibomber:
How's the numbers working out now?
[Galaxy Note 4 Accessories] TheLoneWolf20:
Its getting there, I didn't want to release anything that was going to be buggy or cause more problems. I just wish they had a guide on what the different values do; so I am stuck at doing trial and error.
[Galaxy Note 4 Accessories] unibomber:
It's all good!
[Galaxy Note 4 Accessories] TheLoneWolf20:
Yeah, I haven't been putting time in to do more testing like I should since some things came up and then we have flooding issues in our area which slowed me down even further, but I am getting back to it.

Looks very intriguing but not that great a description on the web site. I'd like to know if the case is a soft kind of grippy rubber or not, a hard rubber case won't do it for me. I sent them an email asking, if it has some grip to it I think I'll go for it.

It would be very helpful for you to use MYDE battery, Thank you very much.
[Galaxy Note 4 Accessories] unibomber:
That's the sane instructions we've all been doing. We have problems with android reading proper battery % off charge
[Galaxy Note 4 Accessories] xeonbuilder:
Those directions won't work. We have been doing that and still not working right. I actually sent my battery back. Sucks but it just didn't work.
[Galaxy Note 4 Accessories] BACARDILIMON:
Actually nick was correct and you are wrong. The issue zerolemon and you have since it is the same battery is showing the right percentage on discharge. It is the same battery. When I get it I will show you then send it back for a full refund. Don't mislead people saying you have fixed the issue.
[Galaxy Note 4 Accessories] Shayded:
It's a tri-cell battery, it will never read properly through android, why do people keep thinking there's a fix possible?
[Galaxy Note 4 Accessories] JOSHSKORN:
Ugh, I wish so many threads that are a bazillion pages could be shut down and restarted by someone diligent and educated enough to keep up with the OP and keep the information current to HELP eliminate a lot of redundancy.
[Galaxy Note 4 Accessories] jacob808:
You guys are stupid! This battery is a great product. Unless any of you idiots can come up with, produce ands manufacturer a better extended battery, STFU! It's no wonder they'll no longer support zerolemon, it's because of yall exaggerated criticism of this awesome extended battery.

It works fine and lasts for 2 days on heavy use and works great with the Gear vr. And no you're not supposed to drain a lithium ion battery to 1%. Which by the way takes forever to even get to 20%.

When you use your gear vr, you'll be happy when you pull the battery and notice it jumps back up another 20%, giving you back all that lost percentage having fun in your virtual experience and won't need to charge the phone again.

You guys are nit pickers and don't know a good product.

Again there is no 10000 mAh battery that will give you an accurate percentage reading besides having a 4 bar Guage.

I don't know what I'd do without this zero lemon battery since it's freed me from having to be close to a wall outlet., and I'm glad I didn't listen to the negative criticism on this thread because I love and can't go back to the original battery after having this.

So MYRE or whatever is the battery manufacturer please keep making extended batteries because I'll buy them and so will millions of others. Don't let these cotton pickers discourage your efforts.

Thank you and have a nice day.
[Galaxy Note 4 Accessories] xeonbuilder:
Thanks for the totally useless comment. It's obvious that you don't have any idea what most of us are talking about. There is a problem with this battery that didn't exist on previous notes. I know I used the battery on my note 3 and it worked fine. It doesn't work correctly on the note 4. No one is saying it didn't last. The problem is it just won't report the correct level so it gets to 1% too fast and you need to remove the battery and put it back in to continue using it.

Bottom line is that there is a problem. Most likely with the phone but never the less a problem that makes this battery annoying to use.

And FYI, if you don't have anything constructive to add to the convoy them don't post.
[Galaxy Note 4 Accessories] BACARDILIMON:
Keep drinking the kool-aid. Lmao

BAD ASS NOTE 4
[Galaxy Note 4 Accessories] BigMosley:
I never got better battery life then the Stock battery UNLESS you keep pulling the whole case apart and do a battery pull multiple times. This is unacceptable, and if you did somehow get the 2 days as you stated, you are one in a million. I am happy your battery somehow magically works like it should, but don't assume everyone else is "Stupid" and slam everyone else's opinion.
[Galaxy Note 4 Accessories] jacob808:
Again if I have to repeat myself, you don't want to deplete a lithium ion battery all the way down to 1%. Lithium Ion batteries don't have a "memory effect" like NiCad batteries and they need to be exercised in order to prolong it's life span. You do this by charging the battery through partial cycles, say maybe anywhere inbetween 30-80% back to full (100%).

Maybe only after 30 of these partial cycles would you want to "recalibrate" the battery and then drain it to say maybe 1-5% then recharge back to 100%.

So with this battery after a heavy days use from morning to night you'll still be at 50-70% charge and then you plug it in and charge it back to full while you sleep get up in the morning and repeat. You'll rarely ever get to 20% charge in one day no matter how hard you try, so it just makes getting to 1% a moot point, that yall be crying about.

The point is as long as you have complete confidence that the battery will not die on you and you won't have to be near an outlet because the battery will last for more than 2 days with HEAVY (i'm talking gaming, youtube videos, Gear VR) then you don't even need to have an accurate percentage reading. Just turn off the percentage and use the battery icon to give you a sense of how much power left, which I doubt will be empty since you'll plug in and recharge back to full at bedtime.

Here familiarize yourself with lithium ion batteries. http://www.techrepublic.com/blog/five-apps/five-tips-for-extending-lithium-ion-battery-life/

---------- Post added at 06:13 AM ---------- Previous post was at 05:52 AM ----------

No way. I'll admit from 100 the percentage starts dropping fast to 99 then 98, 97 etc, but then it stabilises at about 70-80%. From that point even when you tax the phone with videos and gaming it'll deplete about 10% for every 2 hours of HEAVY use. So if you continuously game and watch youtube for 4 hours straight, nonstop, you'll be at about 55-70%. And who TF stays on their phone 4 hours straight besides me? Even if many people did, they'd still have to game another 6 hours nonstop to bring it to 20-40%, and by that time they'd already be heading home getting ready for bed where they can recharge it. If they're not close to home yet, they can do a battery pull and the percentage will jump back up anywhere from 10-30% effectively giving them more than 50% charge again for use.

I'm sure you're exaggerating, like most of the negative critism on this thread about this battery, which irritates me because I almost decided not to buy it after reading this thread, and I'm sure most people won't because of the negative comments on it., but you know what I'm glad I did, and I'll speak the truth so you guys won't put these extended battery manufacturers out of business with over exaggerated negative criticisms.
[Galaxy Note 4 Accessories] BigMosley:
No sir no exaggeration here nor do I have any reason to lie. I would provide screenshots but I returned the battery/case after a week of the nonsense.
