And lastly..... Look at the pic again. Notice the long consecutive time his screen was off. When he was mist probably sleeping. Then look at the graph. See how it's just about FLAT. With a tiny amount of battery usage over that time. Now, it doesn't take anyone with the battery knowledge of me to see this part is accurate and working perfectly as it should. But PLEASE and ANYONE, PLEASE PLEASE explain to me WHY there wasn't even ONE upcharge spike (or recalibration, LOL) during ALL these HOURS!!!!!! Come on people.

YAY! Just arrived!

Initial impressions minus any battery stats of course.

- I was pleasantly surprised by the size and weight of the case. This was my biggest worry before making the purchase as I've never owned an extended battery before. Sure, it's twice as thick, but I like the TPU case. Good design, feels good, etc...

- I actually enjoy holding the phone more now. Although the slim design of the S4 is attractive, sometimes it felt too slim. This feels right in my hands.

- It was a little frustrating trying to get the battery to fit in the slot at first and I was a little worried about breaking my phone in half trying to get the dang thing in. I'm guessing this will loosen up over time as I plan on going back and forth between this and stock depending on my needs.

I haven't tested the sound yet because I'm at work, but I'll report back on that. It's on the charger now so I'll let it sit there for the next 5 hours before work is done, and then charge it in the car on the way home, another 45 minutes. Hopefully we're up to 100% by then.
[Galaxy S 4 Accessories] mjs2011:
Yes, to remove the SD card, you would have to remove the battery. Luckily, my new 64gb shouldn't have to come out for a long time (hopefully).

Unfortunately at work, I have to use an older cable. So far after about 25 minutes, it's already charged up from 59% to 71% though, much faster than I expected. :good:

Thanks for the recommendation on the charging app. I may have to check that out.
[Galaxy S 4 Accessories] wavrunrx:
Not my first charge cycle?

Haha, it was.

As of today I am on my second cycle.

... Also I got my battery on Saturday.

Keep guessing Danny boy ;)
[Galaxy S 4 Accessories] mjs2011:
I believe wanrunx stated on Saturday afternoon when he received it that he was going to follow the instructions and let it charge the rest of the day, so it's feasible that he didn't start using it until Sunday.
[Galaxy S 4 Accessories] wavrunrx:
I'm not going to go out of my way to appease a troll. Sorry friend, but I'm done talking with you. Once again I'm going to request a thread cleaning because you are not being helpful here and this is against xda rules. You have hijacked this completely legitimate thread and levied claims against me stating I'm lying about my battery stats?? What's the deal bro?

I've got no need or desire to do so;

I'm just happy to have such an awesome battery that no other manufacturer has matched yet. ZeroLemon ftw!

Time will show once others start posting screenshots that completely validate my stats, and man oh man, you my friend are going to be so embarrassed.... I *literally* cannot wait to see how you explain yourself.

photoshopping?

Wow just wow....
[Galaxy S 4 Accessories] coolpepp:
Sure
[Galaxy S 4 Accessories] mjs2011:
wanrunx, have fun with this information. Looks like a slam dunk for you. :D
[Galaxy S 4 Accessories] mjs2011:
I do have a question for those that already have theirs. My ZL battery is actually close to 100% already after charging for only 1.5 hours. Since the directions say to charge for 7 hours, should I keep mine on the charger even after it says it's fully charged. I normally don't like to do that with my batteries but I don't want to disobey the instructions either.
[Galaxy S 4 Accessories] coolpepp:
My instructions said to charge it for 12 hours and that's what I did. I was wondering the same thing yesterday.
[Galaxy S 4 Accessories] mjs2011:
Part of me wants to dare to be different and take if off the charger once it says it's charged and then see if I get some of the weird battery stats that you guys are getting.
[Galaxy S 4 Accessories] optimummind:
My battery screenshots so far

Here are my screen shot contributions, still running on my first discharge of the ZeroLemon battery. I expect the battery to die tonight. :)

Just to recap really quick, I received my battery Saturday morning and began charging it around 12PM. I let it charge until 2PM on Sunday and the phone has been on and unplugged ever since.

I rebooted my phone several times, flashing CrossBreeder updates and making changes to the Xposed Nottach module.

My S4 is on stock odexed MDL, rooted, running the second-to-latest ktoonsez kernel, the latest CrossBreeder update, and I have some battery-saving apps installed such as Greenify and Deep Sleep Battery. The screen is on auto-brightness.

And as I mentioned before, the GSam stats seem to have been slightly affected by my flashing of the CrossBreeder mod as values changed after flashing.

Well, onto the screen shots.

In the last picture, there is a green bar. Is that supposed to mean that I was charging my phone? If so, it's weird because I didn't plug in my phone at all since disconnecting on Sunday afternoon.

​
[Galaxy S 4 Accessories] mjs2011:
So that makes 3 people now who have had their battery spike without charging. Let's keep updating this thread to see if it goes away after a couple of cycles.
[Galaxy S 4 Accessories] coolpepp:
I restarted my phone and my battery percentage is more than I had before the restart.
[Galaxy S 4 Accessories] open1your1eyes0:
If anyone doubts that the capacity of this battery is not what it's rated at ZeroLemon has more than enough claims already to prove otherwise with their products in the past. This all started with the Galaxy S III where the tested rating was (for the first time ever for any smartphone battery) actually

higher

than the rated capacity. The OP says everything you need to know and any doubters I recommend to take a good read in this thread:

http://xdaforums.com/showthread.php?t=2102546

Sidenote: No offense to anyone, but as much as a few of you might like to assume and believe that this battery is just another one of those typical fake cheapo eBay batteries, you may want to follow my username's advise. Just saying. ;)
[Galaxy S 4 Accessories] optimummind:
I'm very content with my ZeroLemon battery. I didn't buy ZeroLemon b/c of hype. I just wanted an extended battery and was waiting for Gorilla Gadgets to release one but I bought the ZeroLemon b/c it came out first. I didn't buy Hyperion or Anker b/c of the numerous negative reviews that came up during my research phase.

And I'm sure the battery performance will get better. Based on my 3500mah extended battery experience for my S2, the first discharge battery stats weren't that great either. I started to get 8-9 hrs of screen-on time after about a week of ownership for some reason.

My current stats are still way better than the OEM battery so I'm happy. On the OEM, I would have to charge my phone daily and I would sometimes get five hrs of screen time out of a total of sixteen hrs the phone being on. Eight hrs screen time out of fifty hrs of phone being on is pretty good.

And it doesn't bother me at all what dannyben is posting and also don't care whether he has an agenda or not. I'm happy with my choice, it works well for me, and $40 for an extended battery is nothing to me. I paid about $35 for my Gorilla Gadgets 3500mah & it was worth it & highly useful. I had 3 OEM batteries for my S2 but stopped using them after getting the Gorilla. I don't like swapping batteries out too much.

With my ZeroLemon and 9000mah PowerGen portable charger, I'm set! :D

That fact that the batt covers the speaker -_-... sound, sounds muffled
[Galaxy S 4 Accessories] optimummind:
Final set of photos on first discharge~!

Here are the final shots taken on my first discharge before I plug my phone back in. :D The battery was so low, the swipe-to-screenshot feature didn't work. Not even the Power + Home button~! I took the following shots with my S2. :P

I'm happy b/c now I can update to the newest ktoonsez kernel and another update of CrossBreeder~! :P

I'll post more shots and stats after a few more discharges.

[Galaxy S 4 Accessories] tianmi:
can't wait mine to arrive in NZ, dispatched last week. damn slow post across the ocean.

seeing some screenshots had terrible mobile signal i'd say 7-8hrs screen on time is awesome.

low signal is a battery killer, when i'm at work i loose 3-4% per hour without touching my phone, i'd lucky to get 3-4hrs screen on time within my 15hrs work time with stock battery.

at home with ok signal my phone loose 1% per 2-3 hrs, with wifi on streaming videos i can easily get 7+hrs screen on time.

reading some "screenshot detective" 's statement just make me laugh:D, think he knows everything:rolleyes:
[Galaxy S 4 Accessories] Gulanowski:
Mine arrived yesterday, installed it earlier this evening. My initial impressions are very positive. After installation it listed 58% but almost immediately dropped to 56%. After that I played with it for an hour until it went down to around 45%. When I walked into the gym and left my phone in the car it was at 40%, when I left 1.5hrs later and got into the car it was at 43%...so yes, I did experience a spike. Not sure what to make of that but I haven't even charged it yet so I'll reserve judgement.

I could care less about the increase in depth. Since my E815 circa '05 I've had extended batteries on almost all my phones. This battery's wrapping does appear/feel cheap but that should have no relevance to it's performance. The case is fine and is more or less like the TPU case I had on my Droid Bionic that had an extended battery, which was acceptable for daily use and minor drops (a few feet). I have a Spigen glas.t slim screen protector and the fit is fine. I appreciate the support "beams" placed on the top of the case adjacent to the camera, as well as along the borders of the battery so the case doesn't collapse under pressure. The volume of the speaker is more or less the same, but it does sound muffled and hollow. Due to the depth of the case I expect the camera will retain less smudges.

I can't make any statement as to the duration of the battery as I haven't charged it yet; am currently at 37% at 11:45pm after installation at 5:30pm when it was at 56%. No, I won't post screenshots and provide quantitative data as I really don't care and have more important responsibilities to take care of. Ultimately whether I get 10hrs compared to your 12hrs is meaningless to me; I have 6 apps updating at least every hour, auto brightness and bluetooth always on...maybe I have wifi on all day today, maybe only 4g. There are too many variables and my settings are not the same as yours so it's pointless to compare as far as I'm concerned.

With the stock battery I was barely achieving 4hrs of screentime right before it died, so if I can get around 3x that then I will be pleased. The battery/case is not perfect but that's life; if my expectations in terms of battery life are met then I can live with the muffled sound.

P.S. It was mentioned that ZL is coming out with another/tougher case for this battery. Any pics/additional info?
[Galaxy S 4 Accessories] vlad2277:
Guys, how do you know when the battery finishes charging?

Battery indicator going up too fast

It seems it thinks it's charging stock battery

Does that ever change?
[Galaxy S 4 Accessories] Willie68wr:
They did cover the speaker and the cut outs are underneath the sound on my phone is muffled. :mad:
[Galaxy S 4 Accessories] evolutionqy7:
Any one care to run through whats the story with these? Anytime I click on the link it says not available :(

Running on Anker Extended now, but wouldn't mind getting my hands on the bigger one
[Galaxy S 4 Accessories] mjs2011:
Hmm...not sure. I know the sold out very quickly. I'm sure they'll be back in stock soon though.
[Galaxy S 4 Accessories] mysticjp:
where are the oem sized extended batterys? =o
[Galaxy S 4 Accessories] mjs2011:
More proof that wanrunx wasn't lying about charging his phone. Notice that I have a few spikes so far, but it didn't happen once when I was sleeping.
[Galaxy S 4 Accessories] jev3gs:
Try adding a little tape to open the gap slightly between the battery and the phone to let more sound through. I did and it is way better now. Just look at a few posts of mine earlier to see the picture. Just start with a few layers at first. I started with 2 or 3 but settled on 4 pieces.
[Galaxy S 4 Accessories] graffixnyc:
Thread cleaned... Guys be respectful of each other... This isn't a school yard and you aren't school girls so please stop acting like it.

No warnings or infractions issued this time but if I have to come back in this thread there will be.
[Galaxy S 4 Accessories] mjs2011:
Much appreciated. Sorry for multiple posts I reported. Hopefully this reset will allow for a civil environment between the people that actually own or have interest in purchasing this product.

Thanks again!

So back on topic, although I'm not going to write a formal review until at least 3 cylces (because I believe the most accurate reading will happen at the 3rd cycle), I will say that I'm pleased so far with my battery life. I have had my phone off the charger for 14 hours now. I'm at 85% with 1hr45min on screen time. Not sure if the rest of my original cycle will follow suit but if it does, that will be bout 2.5x the amount of battery I was getting on stock. Definitely not bad for my 1st cycle.

Another thing, I haven't noticed the muffled sound that others have, though I am running Viper Sound Mod, so that might be a positive factor.

More to come.
[Galaxy S 4 Accessories] Gulanowski:
I'm wondering if the phone has trouble recognizing and working with the additional 5000mah of this ZL battery? I was down to 6%, rebooted after reinstalling the battery and it reported 13% upon boot. That, coupled with the spikes I noticed yesterday, as well as having the ZL battery charging now at what appears to be the same rate as the stock 2600mah battery (about 1% per minute) while I'd instead expect it to be about 1/3 of that, makes me wonder if some type of calibration is necessary? If it takes only 2 hours to charge this battery I will be very suspicious as I'd think it should take about 6hrs due to the triple capacity.
[Galaxy S 4 Accessories] wavrunrx:
Yes, I believe there is a need to calibrate, I'm just not sure what the proper way is. Seeing spikes in the battery graph when installing a battery of a mAh less or greater then your previous battery causes fluctuations like this due to old entries in the batterystats bin file. Some people just don't understand this.

Post some screenshots so we can see if your spikes match ours; I promise I won't say you hooked it up to your charger :rolleyes:

Meanwhile if anyone out there knows how we should go about calibrating our batteries within android, drop us a post!
[Galaxy S 4 Accessories] Gulanowski:
Fair enough, I'd be willing to take the time to do that to help identify a problem. However I have swapped between the ZL and stock battery a number of times so my current chart isn't a true representation of the ZL battery. Will need to wait until after the first full charge which I'm doing now. Also how do I take a screenshot?

On purely subjective terms, the ZL battery does appear to take much longer to kill percentage wise.
[Galaxy S 4 Accessories] wavrunrx:
Taking a screenshot depends on your rom, but if your on stock, hold power and the home button, if your on Cyanogenmod press power and volume down
[Galaxy S 4 Accessories] mjs2011:
Yeah, I'm guessing your phone is a little confused. Imagine if your butt grew 3x as large overnight.....ok bad analogy. ;)

I haven't seen major spikes like that. Mostly 1% spikes after having my phone off for a couple minutes.
[Galaxy S 4 Accessories] Gulanowski:
Yeah it's understandable, but that brings me to the ultimate question of how to correlation the phone to work with the 7500mah ZL battery?

Also, how long did it take the rest of you for your phone to charge the ZL battery from more or less dead to 100% using the stock 2mah charger?

I figured out the screenshot; nice. I am stock but rooted (haven't seen the need to flash roms since WM6.1 days). I've heard of apps for those rooted that can delete that battery file and allow the phone to create a new one. Anyone done that?
[Galaxy S 4 Accessories] Willie68wr:
Thanks man it worked :D I don't know if you know about this but if you flash bm sound mod and get fauxsound app it really improves the sound View attachment 2055244View attachment 2055248View attachment 2055251
[Galaxy S 4 Accessories] mjs2011:
I haven't finished my first cycle yet, so I couldn't tell you, but I'm guessing that charging from 0%-100% will take between 4-5 hours.
[Galaxy S 4 Accessories] Gulanowski:
I was thinking at least that, probably closer to 6hrs. Right now I am on track to be at 100% within 2hrs...although the charging rate seems to be slowing down somewhat at 69%.

I work from home so I waited to charge it until I was going to be able to sit there and keep an eye on it. My hope is that the battery simply needs to be calibrated with the phone.
[Galaxy S 4 Accessories] mjs2011:
Exactly. That's why I think it's important to be very cautious with making any snap judgements after the first 2 cycles (at least). From the screenshots I've seen in this thread, I've seen anywhere from 13 hours on screen time to 7. Though I'm still at 81% on my 1st cycle, if the first 19% is any indication (again, I'm cautious to even make this statement because I have a long way to go), I'll end up with about 10.5 - 11 hours screen on time, about 2.3x my average on stock (which was anywhere from 4 - 5 depending on my usage).

I think there's definitely a reason why ZeroLemon says that you need to charge your phone for 12 hours after installing it and then running at least 3 full cycles. A little story from yesterday, I charged my phone for about 4 hours (1 hour past "charged") and it started draining immediately, which pretty much proved to me that even though my phone said it was charged, in reality, the battery was far from 100%. After my battery drained about 3% after 10 minutes, I immediately put it back on the charger and didn't stop charging until 8 hours later....and I noticed a difference right away. I'd be curious to know if everyone here charged theirs initially for 12 hours like the instructions say, and if that's what may be causing a discrepancy in stats on everyone's 1st cycle.
[Galaxy S 4 Accessories] Gulanowski:
Agreed. I plan to wipe the .bat file after a long, full, strong charge of about 12hrs, so figure about 10hrs from now I'll unplug it. The charging rate has definitely slowed down for me around the 65-70% mark, as it is probably pulling 1% every 3 minutes now. The temperature of the battery also dropped somewhat.
[Galaxy S 4 Accessories] optimummind:
I, too, can confirm that my sound output has not been adversely affected, most likely due to the Viper4Android sound mod.
[Galaxy S 4 Accessories] wavrunrx:
this is turning out to be a real winner of a battery !

EXCELLENT upgrade overall !

~13 hours of screen on time ?

U got it ! :good:

glad everyone is enjoying theirs. :highfive:
[Galaxy S 4 Accessories] mjs2011:
Agreed! Like I said, I really want to post some screenshots, but I'm not even below 80% yet after being off the charger for 18+ plus hours!
[Galaxy S 4 Accessories] wavrunrx:
has anyone heard from ZeroLemon when they may release the cases for this battery ?
[Galaxy S 4 Accessories] abalosmusic:
Dunno... Was I supposed to drain the battery before using it? I charged it right away like what the phamplet says. My battery is so so. I'll post stats up later
[Galaxy S 4 Accessories] Gulanowski:
My findings thus far seem to indicate that you should leave the battery on the charger well after it indicates 100%, at least for the initial charge...

I plugged it in at 2:10pm with 11% remaining. At 4:40pm I went out and it was at 89%, when I returned at 6:00pm it was at 100%, yet the notification that says to unplug the phone had not popped up. It was not until between 7:10 to 7:25pm that the notification to unplug came up. The phone and charger were still slightly warm prior to then which leads me to believe that the phone will continue to charge the battery after 100% and until the notification to unplug pops up, which for me was about 5hrs.

I plan to unplug it at midnight and see how long the battery lasts.
[Galaxy S 4 Accessories] mjs2011:
Overall a pretty good start on the first cycle. My hopes are that eventually after everything sets in that I'll achieve around 12 hours screen on time, but I'll take these results so far on the first cycle. :good:

Ps. These screenshots are taken from a phone actually using a ZL battery. ;)
[Galaxy S 4 Accessories] wavrunrx:
wow mannnn i think you photoshopped those stats mannnnn.

/SARCASM

:cyclops: haha, for real though, those are excellent stats !

ill probably never buy a phone ZL isnt going to support in the future.

as much as i like nexus devices, its unfortunate they dont allow access to the battery compartment.

can you imagine the nexus 4 with a 6800 mAh battery ?
[Galaxy S 4 Accessories] mjs2011:
Yeah! And it's getting better too! I just scored a half hour screen on with only a 3% drop! Compare these to my last screens.
[Galaxy S 4 Accessories] vlad2277:
I saw very similar things as you describe on my first run down

Then on first charge I've used various apps to see when battery actually finished charging

The only accurate one was BatteryBut Pro, the rest didn't really recognize huge battery size

It was showing charging almost as fast as regular, but only said battery full after 6hrs mark. Which sounds about right with 2amp charger.

Will see how it behaves down the road...

---------- Post added at 01:59 AM ---------- Previous post was at 01:55 AM ----------

Yes, they said time frame for rugged cases are either ebd if this month or middle of July.

So about within a month.

Really eager to see if new cases worth the money.
[Galaxy S 4 Accessories] wavrunrx:
ok thanks for that;

im eager to see what they look like !

i have NO DOUBTS that ZL will hit it out of the park though !
[Galaxy S 4 Accessories] vlad2277:
Yeah, will see

I was really happy with this battery and case so far

I had S2 before, with extended battery and case, but this case is really well made. Was afraid of ZeroLemon claims that this case replaces both back cover and case, but it really does. Was surprised of plastic supports build into the case.

Definitely no other company does that
[Galaxy S 4 Accessories] oohaylima:
Can't wait either!
[Galaxy S 4 Accessories] nemesis93:
Any updates on the 3000 mah version?
[Galaxy S 4 Accessories] mjs2011:
So when we're talking ZL cases coming in a month, do we mean new back covers? How would they differ from what came with the battery? I'm pretty happy with this one right now.
[Galaxy S 4 Accessories] Daeo:
so from my understanding the 3000 mah will fit with the stock back cover, how bulky is the 7100 mah? i fell in love with my stock otterbox, dunno if i can part with it.
[Galaxy S 4 Accessories] mjs2011:
It's bulky, but not as bad as it looked in pictures to be honest.
[Galaxy S 4 Accessories] jlrogers:
