I am still confused guyss... should i get the 7500 mah one or the 3000 mah one..??? I have no use of NFC.. but i wouldn't want to change my battery twice after removing my case and back..!! Also i would like to retain the slim profile of the phone..!!
[Galaxy S 4 Accessories] vlad2277:
Get app called adjBrightness

It's the only one that can adjust brightness once that minimum dimming kicks in at 5 %
[Galaxy S 4 Accessories] nemesis93:
Depending on your usage, the 3000mah would be better for you. It's the only way to go to retain the stock thickness of the phone.

On the other hand, if you need 6+ hours of screen time and 18+ hours of up time you should go with the 7500mah.
[Galaxy S 4 Accessories] slackwaresupport:
just got my 7500 in.. charging now. hope it works well! ;)
[Galaxy S 4 Accessories] ponts:
I can get this from my seido 4500mah battery and its a lot lighter and a bit thinner.
[Galaxy S 4 Accessories] nemesis93:
Isn't the seido like $70??
[Galaxy S 4 Accessories] optimummind:
Yes, but not > 50 hrs total uptime + > 10 to 13 hrs of screen-on time with autobrightness and normal usage. :p
[Galaxy S 4 Accessories] ponts:
I got mine for $62 shipped. I think the seido brand combined with the lighter and smaller footprint with similar runtime may be worth consideration for some.

Probably not......
[Galaxy S 4 Accessories] rhd-android:
The ZeroLemon 3000 arrived. Tested the cell's true capacity at 2890 mAh. Absolutely no complaints with that!
[Galaxy S 4 Accessories] coolpepp:
I thought I read somewhere in this thread but I can not find it that once the battery hits 20% or some other percentage, the battery seems to last longer than it seems. In other words you cannot go by the battery monitor because even though it say 20% you actually have more battery left than that. Today is the first day that I am trying to see how long my battery will last till it dies. So far I am at 19% with 1 day 1 hour 56 minutes with 4 hours and 15 minutes of screen time, and 2 hours and 25 minutes of phone use. My screen is on auto-brightness with it all the way up and have WiFi, gps, Bluetooth and NFC on the entire time with a live wallpaper running.
[Galaxy S 4 Accessories] Leoog:
This app says it requires root unless I looked up the wrong one in play store.
[Galaxy S 4 Accessories] rhd-android:
That's very possible!

Many people don't realize that it's not actually possible to verify the amount of capacity left in a cell directly. The only way to estimate capacity is to check the voltage of the cell. Then the voltage needs to be compared against a voltage capacity curve for known lithium-ion cell. The challenge, is that not all cells have exactly the same curve.

So a voltage that might correspond with 20% remaining capacity on a typical cell, might correspond with 25% actual capacity remaining on a cell that deviates a bit from the average curve. Your phone doesn't know this, and thus reports 20%.

I'm sure the phones these days are smart enough to tweak the default curves a bit over time. I would be shocked if they didn't. But for those of us who swap cells, tweaking the discharge curves, assuming our phones do in fact do so, would not be any help.

i got my zl 3000 mAh battery today. going to go by the exact procedure the battery came with. going to charge it for 12 hours on my charger and take it from there. i did put it in the phone and with the sticker i can get the back closed, but it was like putting on pants after thanksgiving dinner. if i decide to keep it i will probably remove the sticker as i have a qi receiver unit coming sometime next week and need all the space i can get. :good:
[Galaxy S 4 Accessories] vlad2277:
Yes, root needed for most of stuff

Without it, almost nothing could be changed that not already build into phone.

I should be getting mines this week, and i will be reviewing it.

---------- Post added at 12:42 AM ---------- Previous post was at 12:41 AM ----------

how did you did that?:cyclops:
[Galaxy S 4 Accessories] devindra1242:
I put my ZeroLemon 7500 in the closet. Honestly I don't think the tradeoff is worth it. Huge size, reduced reception and muffled sound. I just bought two spare batteries so I can switch them out.

Most ppl don't even need this battery. I'm sure many have access to a outlet throughout the day.
[Galaxy S 4 Accessories] vlad2277:
Sure, forget cell phones. Even cordless, let's just use mile length land line phones.

You sound like someone who never had this battery, maybe even Galaxy 4 phone. There's 30 days money back guarantee. No one would spend 40 bucks, throw it in closet and buy another two spare batteries.

When you could easily spend like 4 bucks and send it back with tracking, and get your money back. If you really unhappy.

This phone is way too powerful, and power needs energy. And people love freedom, not going from outlet to outlet, that's something busy person doesn't want to think about throughout the day.
[Galaxy S 4 Accessories] blackknightavalon:
I can verify that. This battery refuses to die.
[Galaxy S 4 Accessories] eakeller:
You're questioning whether or not this person owns the phone and battery they say they do? Really?
[Galaxy S 4 Accessories] rhd-android:
I am constantly amazed at how defensive people get about this battery. You're defensive to the point of suggesting that someone is lying about not returning a $40 battery? Even a true expert in human behavior, which I'm sure none of us techies are, wouldn't be as arrogant as to suggest that they could call the act of not returning a piece of electronics completely implausible.

For what it's worth, I know lots of people with graveyards of unused tech that they could have, and should have returned for bigger refunds than $40, but didn't.

But that's not the point really. The point is that it's obnoxious to call someone a liar because they don't like a battery that you happen to like. My god....

[Galaxy S 4 Accessories] vlad2277:
Exactly, you just proved my point

Not saying this battery is perfect

But my point was simple

It's not about $40, it's in human nature

No one would buy anything, use, test, and after being unhappy with purchase, just go back and buy two smaller items for another $40.

I want to see people you talking about who would say buy lets say LED TV for $1000, don't really see it's worth over cheaper model, just throw it in closet, and buy LCD INSTEAD for $500.

Pros and cons of this battery are obvious, but you can inky compare them to other extended batteries and other cases for extended batteries.

You can't start comparing big to small.

Just like you can't compare apples to oranges.

If you want/need power for whatever reason, you pick and choose big bulky battery.

But can't start playing dumb saying wow, 5000 extra mah makes phone thick, heavy, signal lost, can't make calls

Forget about it, just throw it in garbage
[Galaxy S 4 Accessories] optimummind:
What I noticed in this thread that there are some people who act defensive about their purchase of this battery and also those who seem like they're competing vendors of this type of battery and want to muck the reputation of this battery. I think both types should stop and only post their fair and objective impressions and results.

Otherwise, it just pollutes this thread with crap for people who are looking for useful info.

As for my experience with this battery, it's been great. I don't mind the additional heft nor size and I love the super long screen life it can give me. And now that I have painted the stock white battery cover blue, I no longer have to stress about the cover appearing dirty too quickly. And I have no signal degradation issues with the ZeroLemon battery either.

As for sound, I'm getting great sound with the Viper4Android mod - the sound is louder and more clear than with the OEM battery cover on. :D

Sprint GS4, stock rooted MDL, ktoonsez kernel, CrossBreeder
[Galaxy S 4 Accessories] Gulanowski:
There is definite signal loss with this battery. I estimate it anywhere between 3-5dbm. I tested 6 areas of the house with both stock and ZL battery and the results were always slightly lower (i.e. stronger) dbm readings with the stock battery. For one spot this is a real problem because the ZL battery will cause the strength to hover at -91dm which is the threshold at which it seems the S4 reverts to 3g. With the stock battery it'll hover between 85 to 87.

So I need to seriously consider whether the great life is worth the drop in reception. I may try the Seidio 4500mah battery + activex case. Definitely more money but I really liked that case on my old DroidX.
[Galaxy S 4 Accessories] eakeller:
*raises hand* I hate to admit it, but I've bought items and shoved them in a closet while buying something with the same function which better fit my needs. Usually I've had every intention to return the first item but for whatever reason haven't gotten around to it. So your claim of nobody just fell flat.

Your attempted analogy of TVs is ridiculous. Talk about apples and oranges. A battery isn't a TV, nor is $40 anywhere close to $1k.

Welcome to the internets, 15% useless cr@p, 24% fanboi flame wars, 1% worthwhile reading, 60% p0rn.
[Galaxy S 4 Accessories] devindra1242:
I would gladly return this battery but I spray painted the back cover so it is unlikely they will give me a refund.

It is like some of you believe you are reps for this company and become so defensive. Scratch that... I wouldn't be surprised if some of you were, they put fake 5 star reviews up for their products on Amazon.

This is coming from someone who had a ZeroLemon for their s3.
[Galaxy S 4 Accessories] vlad2277:
So you were not happy of s3 ZeroLemon as well?
[Galaxy S 4 Accessories] mjs2011:
Wow. Reading the last page or so of this thread is the very reason why I checked out of this thread a week or so ago. So much immaturity flying around.

I was going to write a review today that I thought would be considered neutral but I think I'll pass.
[Galaxy S 4 Accessories] vlad2277:
If anything, you should consider writing review on Amazon
[Galaxy S 4 Accessories] Aitch:
Great fight dudes lol!

Unfortunately I can't tell who won so maybe someone needs to deliver a headshot to decide who is the true champion! FATALITY!

Also, can you buy these ZL batteries in the UK?
[Galaxy S 4 Accessories] vlad2277:
There's absolutely no fighting

As far ad I can see, everyone just speaking out there own opinion.

No cursing or anything

All pretty much civil.
[Galaxy S 4 Accessories] blackknightavalon:
People will continue to think what they want. I stand by my personal review of the battery.
[Galaxy S 4 Accessories] oohaylima:
Some people feel the need to defend a position due to self identification with the object. Nobody likes to feel as if their investment was worthless. And my amazement is the same.

Some people just got money like that. Y u hatin bro? :P

You got a lot of porn on your internet. :D

Brother, if you need to get rid of it, I'm your man. How much do you want for it?

Put your review up here pimpin. It would be a breath of fresh air for us readers.

Has anyone been able to fit this battery inside of a modded otterbox defender?
[Galaxy S 4 Accessories] optimummind:
What a difference having good signal makes on battery life~!! For the past 3 weeks at my work area, Sprint has been having reception and data problems due to a cell outage at one of the nearby towers. Today, the reception has been really good and my data began working again, although it's just 3G. :P

At the point of these screenshots, my phone's been on for 6 hours and 23 minutes.

For the past 3 weeks when Sprint was having reception problems, my battery left after 6 hours with the same ~45 mins of sccreen-on time was 78% to 85%.​
[Galaxy S 4 Accessories] SIGHTFIRE:
I very curious if anyone has come up with a modified case solution as well?
[Galaxy S 4 Accessories] vlad2277:
According to ZeroLemon new rugged case for extended battery would be out in about 2 weeks.

So we'll see how good it is.

But the one that comes with battery is already pretty good.
[Galaxy S 4 Accessories] MR8SIN:
:D ZL 3000 results. Chrome,Email,Texting,FB, and Auto Brightness.
[Galaxy S 4 Accessories] rhd-android:
I'm having great luck with the ZL 3000 as well. It's lasting, unsurprisingly, about 10% longer than stock (which is exactly what it should be doing, since it has about 10% more true capacity than stock).

It's the clear winner if you want to retain you phone's slim profile, and don't care about NFC.

I have a QI charging receiver en route. I'll be interested to see if it fits in alongside the ZL 3000 (which is slightly thicker than stock... 1mm or so)
[Galaxy S 4 Accessories] optimummind:
After having owned both the 7500mah & 3000mah ZeroLemon batteries for a while, I truly love both products. Awesome battery life and the 7500 comes in real useful especially over the weekends. And I love that the 3000 package came with a charger for under $20.
[Galaxy S 4 Accessories] robotphood:
That's amazing screen time. Any other tweaks mods or special settings?
[Galaxy S 4 Accessories] nemesis93:
Holy cow I get nowhere near that. What rom/kernel/mods are you running???

I know that part of the reason my battery life isn't so great is the fact that I have bad reception on sprint. With this ZL 3k mah battery I get about 17hrs off the charger and about 5 hrs screen time.
[Galaxy S 4 Accessories] drenco:
UPDATE: ive been using my 7500mAh ZL battery now and have just finished the 6th cycle of down to 1% then charge up to full again etc overall ive been getting excellent battery life the last cycle i deliberately made light use of the phone (for me anyway) to which i got 5 days 13hrs standby thats with WiFi & GPS switched on near MAX brightness includes 5hrs screen time (gaming,internet,navigating menu's etc) & 5 hrs call time) loving the performance of the battery but definitely not loving the slippery feel of the TPU case combined with the extra weight it feels like an accident waiting to happen (put it this way ive never felt/held a phone case this slippery before) and the battery definitely muffles the sound quite abit as it obviously covers the speaker on the back so when playing games it does sound awful to be fair. SO mostly positive but unfortunately not perfect.
[Galaxy S 4 Accessories] MR8SIN:
Completely stock. Never rooted. No smart options. No air options. 643byte black wallpaper. Disabled bloatware. LTE was on for 6hrs rest was on 5ghz Wifi. No calls were made. Otherwise I usually can get 6.5hrs talktime and 4.5-5hrs screen time when im at work.
[Galaxy S 4 Accessories] minirx7:
As I mentioned in a prior post in this thread all you need to do for the muffled sound is to jam a small piece of paper under the batter and above the charge port. Then you sound will be crystal clear and loud

QI wireless charger + 8000mah Li-Po battery:good::good::good:

[Galaxy S 4 Accessories] jkbane:
Here is my 1st Cycle experience

First, lets talk about the results from using the battery. Per the instructions for the best performance you are to go through 5-6 cycles. For this review I only went through one cycle. The instructions also encourage you to leave the phone on the charger for 12hours for its first charge, which I complied.

The result was getting two and half days worth of battery life. Check the video for a full explanation. In short, I have full brightness on most of the time, 4G over WiFi, lots of automatic push notifications, emails pushed and streaming services being used. I would consider myself a heavy user. If you are not a heavy user, you will for sure get better battery life than I.

The TPU case is really tough and is a perfect fit for the battery and phone. There are white and black covers available to choose from. The surface is smooth but not slippery and is pocketable. Cutouts are great. The power and volume controls are covered up and require a little bit more effort to press as if the case was not installed.

The NFC capabilities works great. I tried it out on TYLT NFC Tags stickers and car mount and I had no issues at all.

Overall, for an extended battery with NFC it performed well for me. It was exciting to see two and half days of battery life on a smartphone. That was a first for me. I don’t know if I could use this as a daily driver because the thickness and heaviness got on my nerves at times. I like my devices thin and not as heavy. This battery will definitely get you through the weekend or would be a nice travel companion for anyone not able to charge the device on demand.

[Galaxy S 4 Accessories] Zenzr:
Are you guys leaving the phone on auto brightness? I'm confused how your battery hours are so high. Granted I'm only on my first cycle so I suppose it gets better.

Also I seem to drop signal a lot though I don't know if it relates to the new battery or not as it happened before too.
[Galaxy S 4 Accessories] jkbane:
I normally keep full brightness on all the time.
[Galaxy S 4 Accessories] Zenzr:
I'm assuming then auto brightness is probably the culprit then.
[Galaxy S 4 Accessories] namtuvuong:
Thanks for report! I consider to buy one pack!
[Galaxy S 4 Accessories] Zenzr:
I'm not sure what changed but I'm running much better on my second cycle.
[Galaxy S 4 Accessories] kenny111008:
So is anyone getting some battery drain with this new software update? I definitley notice drainage
[Galaxy S 4 Accessories] Phatdawg:
It's probably from google services, if it is you need to turn off location via wifi and also take off the setting for location access while phone is on, in the google settings application.
[Galaxy S 4 Accessories] kenny111008:
Nope ive done that since I first got the battery. This only started happening after the uodate. Nothing seems to be draining my battery when I check the stats but the numbers I usually get w. Screen on time and unplugged time arent the same
[Galaxy S 4 Accessories] Phatdawg:
Looking at the screen shot of your battery, it looks like your google services are draining your battery as well. You would get a 15-19 percent boost from getting rid of their intrusive tracking mechanism.

---------- Post added at 02:02 PM ---------- Previous post was at 01:53 PM ----------

Can you post a picture of your battery stats/info?

Thanks
[Galaxy S 4 Accessories] kenny111008:
At 49% before the update I was usually at 6 hours of screen on time by now. As u can see 49% and it's barely above 2 hrs of screen time. In my opinion for my use theres a drain.
[Galaxy S 4 Accessories] cesardrgn:
Is just been two months since I got my S4 and I got a nice case for it too but I will get this battery one of this days :)
[Galaxy S 4 Accessories] optimummind:
Not me. I'm getting better battery life. Just yesterday, I got almost 7 hrs of screen time and I was at 65% left.

I am, however, using the ktoonsez kernel using his settings and the -50mV.
[Galaxy S 4 Accessories] kenny111008:
Well I am completely stock no root or nothing.

For those looking a slightly slimmer profile, the honey comb extended case fits. I also cut the battery cover.

Hi

I'm new to the forum and looking at battery for my galaxy s4.

i came across a piece on anandtech.com and they ran some benchmark with some crazy results. Want to see if anyone getting the same results here.

Trying to compare some real life results with these benchmarks

now our galaxy S4 looks like the Motorola Startac.. hahaha..
[Galaxy S 4 Accessories] Duckers McQuack:
Can someone with the 7500mah please post a screenshot of the battery at 10% left after having big games like modern combat 4, nova 3 and such running? Cause i wanna see how long i can game on one battery.

I'm using the app and I thought it was the last page as it normally sends me to the last page of a thread.

Simply mistake. No need to be rude.
[Galaxy S 4 Accessories] SilentEYE:
No rudeness. Just wanted to inform you
[Galaxy S 4 Accessories] jkbane:
10-4 my intention was to be helpful
[Galaxy S 4 Accessories] jev3gs:
Just in case if anyone does post this you should keep something in mind. Since this is 3 batteries hooked up to make look like one you will notice that the battery may drain quicker than expected. Then you leave the phone alone for like 30 minutes and then it has more battery life therefore not giving you an exact reading on what was used.

I was playing Bards Tale for like 2 hours, can't remember what battery percentage I started at. When I stopped I was like at 32%. I left the phone alone and came back to it half hour later and it was over 40%. It sounds crazy but it is perfectly normal since the batteries are all balancing themselves and when that happens the battery with the tech that can actually read battery percentage will go up or down.

I just know you should be able to game for like 4 hours easy if the phone doesn't overheat, you just may need to take a break for 30 minutes.
[Galaxy S 4 Accessories] lilmikey201:
can anyone tell me the results of the 3000mah battery
[Galaxy S 4 Accessories] SilentEYE:
Many people helped us to give specific informations about this battery. I got mine (7500mah) last week and I wanted to say THX and share my first-cycle-stats experiences.

Phoenix ROM with Ktoonez kernel

- Mainly 2G Data

- Flightmode at night for 5 hours

- Rebooted ~8 times for flashing stuff and doing a full Backup (~1 1/2 hours totally)

- Greenify and some security apps.

- 4 mail accounts, Whatsapp

- 30 mins of navigation

- Screen mainly on auto

- Bluetooth transfers, pictures, etc....

Max screen time could be 12 hours, because the battery resisted to die and stuck at 3% :silly:

Pro

- more easy holding smartphone now

- battery life

- soundoutput better when laying on the backside

- good grip, less slippery

- now also available in europe (amazon.co.uk)

- fair price

Cons

- a bit too thick

- signal problems from time to time esp. when holding in your hand on places with poor reception

Zerolemon 7500mah Battery Review

Hey, guys! I did a review of this battery on my Youtube channel (there's a link to it in my signature) :D Got some crazy battery life with it!
