I also have these little peaks in the charging graph. The phone has not been on a charger since charging to 100%. Weird.

I'm on my second full charge/discharge cycle. I'm getting better results on my second cycle.

Did a small mod to lift the battery off of the speaker. The speak actually sounds louder than stock.

The thicker phone is actually easier to hold than stock.

The battery life is more than impressive.

Can't be any happier...
[Galaxy S 4 Accessories] mjs2011:
Nice! You're well on your way to 12+ hours! Do you mind me asking how many hours screen on time you received on your first cycle? I'm still on my first and I'm thinking I'm going to be around 10.5 to 11 hours.
[Galaxy S 4 Accessories] abnormal1379:
I believe I was also around 11 hours screen time on my first charge cycle. I'm guessing that's the norm?
[Galaxy S 4 Accessories] mjs2011:
Must be, yes. I saw one person who only had close to 8 hours but I'm guessing there were other factors contributing to that.
[Galaxy S 4 Accessories] nemesis93:
Anybody willing to provide me with measurements for the phone with the cover and battery in regaurds to thickness?
[Galaxy S 4 Accessories] coolpepp:
To me its pretty thin. Its 2 mm short of 2 centimeters.
[Galaxy S 4 Accessories] mk262:
I'm still confused about why this requires 12 hours of charging followed by 6 full charge/discharge cycles. That is the opposite of what I've always read lithium ion batteries need. Can someone speak to this?
[Galaxy S 4 Accessories] optimummind:
I think they recommend those steps b/c it takes time for Android to "get used to" and discover the existence of a 7500mah battery. What I do with my extended batteries is charge it for a long time even after hitting 100% then calibrating the battery with a root battery calibration app. This method has worked for me successfully and i don't have to spend time going through the charge-discharge cycles.
[Galaxy S 4 Accessories] vlad2277:
You can't judge anything just by screen time amount

It depends on brightness level

If you have it on auto, or manual

If you use it outdoor, then brightness would be high, indoors, low

So in real life you could get from 8-11 hrs of screen time.
[Galaxy S 4 Accessories] mjs2011:
Yep. Agreed. It only tells half the story.
[Galaxy S 4 Accessories] Gulanowski:
So far so good. I'm at about 23.5hrs since unplugging, with about 4hrs 51m of screen on time and have 52% remaining. I've had some spikes as the chart reflects; I only lost about 3% while I was sleeping so I assume the percentage bumped up and ultimately down. Again while I was lifting at the gym and the phone sat in the car for an hour the percentage went up by 2%.

I also noticed a program called "google services" which it claimed ate up the majority of my battery. I doubt it is a correct report as my "screen on time" to remaining battery percentage ratio is on par with everyone else (about 5 hours screen time per 50%) so I am guessing it is some main component of android OS, or is incorrectly reporting it's use. Does anyone know for sure?
[Galaxy S 4 Accessories] wavrunrx:
i see some peaks in those screenshots.

u sureeeeeeee u didnt plug it into your charger ? :P

thanks for the report man. :good:

looking forward to the day [MENTION=4073507]dannyben[/MENTION] apologizes to me and the rest of us for his actions.

over and out.
[Galaxy S 4 Accessories] Gulanowski:
Haha yes, quite certain. With the stock battery I was getting a little under 4hrs screen time with about 16hrs of total life. Currently I'm on track to score over 10hrs of screen time with over 48hrs of life. So with the ZL 7500mah thats roughly three times what I was getting on the stock 2600mah battery. I'd call that very fair and reasonable. Obviously daily usage will cause it to fluctuate a little but so far I am very pleased.
[Galaxy S 4 Accessories] mjs2011:
Lol won't happen. But I think the best exit was him posting screenshots of a stock battery and trying to claim that it was a ZL battery....and none of us feel for it or even have him any attention! Haha!

Glad that drama is over and good to see everyone enjoying the battery so far.
[Galaxy S 4 Accessories] gravedigger76:
Guys, would ZeroLemon from S3 work on S4?

(Case and battery i guess).
[Galaxy S 4 Accessories] lambstone:
Battery yes. Case no.

S3 batteries have been known to fit the s4 with a little horizontal margin
[Galaxy S 4 Accessories] Gulanowski:
So I looked into this further and it seems to be a fairly well encountered issue with no definitive answer. I think "google services" is more or less a catchall for the sync functions that google performs. So I turned off google now, all the gmail syncs and maps reporting. Hopefully that is the end of that using the battery, although I don't think it was using that much. I'll know after the next cycle.
[Galaxy S 4 Accessories] jdcnosse:
Anyone have any pictures of the battery and tpu case when in/on the phone as compared to the stock battery?
[Galaxy S 4 Accessories] mjs2011:
Nearing the end of my first cycle. Pretty fantastic. These screenshots are not photoshopped. ;)
[Galaxy S 4 Accessories] frrlod:
How are you guys feeling with holding the phone in your hand with the huge battery? I'm considering buying one but it looks huge.

Also, aren't you worried about not having a protective case?
[Galaxy S 4 Accessories] blackknightavalon:
1) The battery cover doubles as a protective case, and I've never found use for one.

2) The phone feels more comfortable with the added weight.

Also, going on 21 hours (with two reboots) and I'm at 44% power left.

I posted this in the results thread as well, but realized this is really where it should be -- I edited the other post with a link to this one.

Have a question for others using the ZeroLemon S4 battery, especially on a Verizon GS4 -- have you noticed a decrease in signal strength vs either stock or Anker/Hyperion extended batteries/plastic covers? Doesn't have to be a fringe area necessarily.

I posted this review regarding signal strength:

http://www.amazon.com/review/R2P0EL6K1E06CB

I haven't gotten any feedback from ZeroLemon yet, but wanted to know if anyone else is experiencing this. You can get dBm and asu values under Settings -> More -> About Phone -> Status.

I haven't updated the review yet, but I switched batteries at work, and sure enough, when the ZeroLemon battery is used, I get a signal strength degradation. Since I am in a fringe area already, the phone goes from sporadic 1x data available/calls can be made/txts send somewhat reliably to no data/no calls/txts can send only if you dance around on one foot twirling an umbrella

The miniature hundred millisecond range bursts of no-signal / switching to/from eHPRD from 1x data that happen sometimes while on stock or Anker/Hyperion extended become a NO SERVICE for up to a minute or more with the ZeroLemon battery at work.

I might have to try this battery on a US Cellular and/or Sprint phone to see if the signal degradation results are the same...

If anyone has a GSM version of this phone I'd especially like to see if this issue is present for you... or anyone else that has a ZeroLemon battery on their GS4, for that matter.
[Galaxy S 4 Accessories] wavrunrx:
sofar your the first person to post about it
[Galaxy S 4 Accessories] roscoe08:
I have the Verizon with the zl battery and no signail degradation for me it stays the exact same.
[Galaxy S 4 Accessories] blackknightavalon:
No signal degradation on the T-Mobile S4.
[Galaxy S 4 Accessories] vacaloca:
Thanks for the feedback.. so far you and blackknightavalon mention no issues, no e-mail back from their support yet which is strange. I ended up returning it, but it was annoying to have to pay $6 in postage just to do that... so I might not get a 'replacement' unless they switch to fulfillment by Amazon again, especially given the lack of a response from them.
[Galaxy S 4 Accessories] Uvfriend:
Yup I am having same problem... Mine doing that too.. For some reason when at work where I use to get 3g inside the building its 1x and even when I am connected to WiFi it looses both signal and WiFi network for few seconds periodically...
[Galaxy S 4 Accessories] minirx7:
I got my zero lemon, and the sound is very muffled and your right. small mod to lift the battery off a bit makes a HUGE difference in sound
[Galaxy S 4 Accessories] optimummind:
I recommend the Viper4Android audio mod. It'll probably increase your sound quality even more.
[Galaxy S 4 Accessories] devindra1242:
How exactly do you perform this mod?
[Galaxy S 4 Accessories] minirx7:
Just stuck a small cardboard between the back and the battery.

What's happening is the case is pressing the batter down too tight against the phone muffling the sound
[Galaxy S 4 Accessories] abnormal1379:
I did something similar to what this poster did here:

http://xdaforums.com/showthread.php?p=42685537#post42685537

Instead of using stacks of eletrical tapes, I used pieces of foam tape about 2 to 3 mm thick. It raises the battery off of the surface of the speaker, but not enough where the case won't fit. The foam tape has some "give", so even if the tape was too thick, it compresses down when I put the case on.

[Galaxy S 4 Accessories] LAcharger:
so I'm considering buying this extended battery for my s4 but am not really a fan of the case.. was wondering if you could squeeze it into a case such as yes trident brand or something similar? would appreciate any feed back. thanks guys
[Galaxy S 4 Accessories] Pickleweasel:
First charge out of the package and this is what I got. I am pleased so far :) the spikes in battery was from me using it then putting the phone to sleep and the phone adjusting to how much juice this thing has. When I turned the screen off the battery would go back up 1-5% lol I'm on two percent now and used it down to one percent and put it to sleep so I could go find my charger and it went back up to two percent again... I don't know whether to charge it yet or not lol my hyperion 5200mah would last 2 full days of my normal usage but this has gotten me 3 full days with the same kind of usage on the initial charge. Hopefully I can squeeze a little more out once it's broken in a little.
[Galaxy S 4 Accessories] Orical:
I'm buying it for sure but what's the back like that they send with it, is it more durable than it seems in the pictures ?
[Galaxy S 4 Accessories] Pickleweasel:
II like it, it's pretty sturdy and has a nice texture to it that makes it feel like I can get a nice grip on it. If they come out with a rugged case for it I will probably get it but I am happy for now :)
[Galaxy S 4 Accessories] blackknightavalon:
It's very durable and it lasts a VERY long time. It took 35 hours off of one full charge (moderate use) to get it below 5%.
[Galaxy S 4 Accessories] Gulanowski:
Mine just died (literally 0%) from the first cycle. Almost made it to 2 days; it died at about 47.5hrs in. I had over 10hrs of screen time, probably about 10hrs, 15min. I had bluetooth on the whole time, auto brightness and almost never turned on wifi except momentarily to download something. I'd post the screenshots but I'm going to give it a break for a while.

This is easily a 1 day heavy use/2 day moderate use/3 day mild use battery (we'll see about that last one - I plan to run the phone on the next cycle as I normally would, which is mild to moderate use with wifi on).
[Galaxy S 4 Accessories] vlad2277:
I'm finishing my first charge cycle tonight , 2% kefy

60hrs already

11 screen time

I thought it would be more, but had to use GPS for about an hour with high brightness set in sunlight

But it's pretty good.

Regarding signal strength, without going into deep long testing ,I could say that signal might be just a bit less on extended, then on stick

But it's very minor loss, nothing that would I even consider if any value
[Galaxy S 4 Accessories] hisname:
Maybe this is a little off topic but does this come with a charging kit??
[Galaxy S 4 Accessories] vlad2277:
No, it's not

You need to use stock charger

It takes me 6hrs, from zero to full.

If you need additional, I found dame brand name Samsung on Amazon for $12

But you need to make sure to use 2amp charger if you'll be using another brand

Otherwise battery this size will take you 12 hrs to charge
[Galaxy S 4 Accessories] hisname:
6 hours? wtf? :eek:
[Galaxy S 4 Accessories] vlad2277:
6 to charge?

What too long for you?
[Galaxy S 4 Accessories] Nasty_z:
[MENTION=2161533]vlad2277[/MENTION], are you saying that it takes 6 hours to go from 0-100?

or do you leave it on charging for a couple of hours even after the phone displays a 100%? Because on the amazon page, Zerolemon has said to charge the phone for 2-3hrs more after the phone displays a 100%.
[Galaxy S 4 Accessories] vlad2277:
Well to be exact, let me explain

I use stock Samsung 2amp charger

Right now I already charged battery twice and saw exactly same charging pattern.

I use app called BatteryBot Pro, to have clear picture of charging process

It takes almost 4hrs to go from 0 to 100%, then another almost 2hrs till the program says Fully Charged 100%.

Both times, I was home at the end of battery life, so I let it run down completely to 0.

ZeroLemon recomends to charge fully at least forst 5-6 times, so will try to do that
[Galaxy S 4 Accessories] Nasty_z:
Thank you, I just got mine today and that app would no doubt help me as well.
[Galaxy S 4 Accessories] ponts:
Edited, forgot zerolemon uses a buikt in case.
[Galaxy S 4 Accessories] rhd-android:
ZeroLemon has a great idea in the way they design their extended batteries...

...and I can't wait until that idea gets copied by someone who can actually fulfill orders, and to more than 2 countries.

I DO care about the topic mate. I like the battery and want one. For whatever reason, ZeroLemon doesn't seem to want to sell them to Canadians.
[Galaxy S 4 Accessories] minirx7:
This battery is really amazing!!.. I am trying to drain my battery down through regular use and it refuses to die..

Since Friday 9am to Saturday 9pm.. Still at 47%..

My stock battery barely lasts a full day..
[Galaxy S 4 Accessories] vacaloca:
Glad to see it's not only me. I had given my old Galaxy S3 w/ a ZeroLemon battery to my sister, and she mentioned that the WiFi connection was slow upstairs (router is downstairs). I went upstairs with my GS4 with the extended Anker battery/case and managed 25Mbps down and 5Mbps up as the Comcast connection was configured. I tested hers and I never could get it past from 5Mbps down, and usually only from 1-2Mbps. When I replaced the battery with one of the old extended ones I got, she was pulling in 15-25Mbps... so it doesn't seem isolated to the GS4 battery only... happens on the S3 also.

I'm going to see if I can return the S3 one as well... for what it's worth, this only happens when the WiFi and cell radio signal strength is already low/degraded to the point that the extra loss brings in disconnect/slow speeds/etc.. so if you frequent areas where WiFi/cell signals are not strong, it might be worth to test if this is an issue.

Mine has been doing the initial charge for about 10 hours, and has been hovering around 95% for the last 3 hours. Hopefully it's at 100% by the time I wake up.
[Galaxy S 4 Accessories] vlad2277:
That's impossible !!!

You must have connected a charger and that phone recognized it as USB, not AC.

That's the only logical explanation, since maximum charge of USB is 500 mah.
[Galaxy S 4 Accessories] paincorp:
It's been connected to a 2.1A charger since 2pm. Granted I just realized that charger is now buzzing, so that might be part of the issue....just plugged it in to another 2A charger, we'll see what happens.

Edit: Jumped 2% in a few minutes on a different charger, looks like we found the issue, hope I didn't kill a 2A charger.

Edit 2: Yup, looks like the charger took a dump a few hours ago, at least judging by how my battery is now up at 100%.
[Galaxy S 4 Accessories] vlad2277:
Was it OEM Samsung charger? With original USB cable?
[Galaxy S 4 Accessories] paincorp:
No, due to my schedule I had to use another 2A charger since I was on the move today. Not ideal, but oh well.
[Galaxy S 4 Accessories] vlad2277:
No guarantee that another charger was 2amps, if it's like generic, they lie

Plus, there's a good chance you used regular USB cable, max output is 1amp

But when galaxy 4, checks cable that's not hi-speed USB, it thinks you connected it to something other then AC outlet, so you will get 500 mah charge, not even 1amp.

I know this through research and experience. Was trying to figure out why my car charger wasn't supplying high speed charge, then realized that both charger and cable must be capable of hi-speed.
[Galaxy S 4 Accessories] paincorp:
Charger does output at 2A, I know that.

I've never had that issue on my other phones, and my car charger is 2A. I know the cables and charger combined are pushing 2A to my hotspots as they are charging much quicker than if at home and are able to power my phone with GPS, screen and BT playing music without much loss compared to what I was getting previously. Oh well, live and learn I guess.

Don't mind me asking, and I don't want to sound cocky here, but why would you be so interested in a 3000mah when the only benefits you'll see is maybe 1 more hour of on screen time?
[Galaxy S 4 Accessories] louiscyphere13:
There's a company making a 7800mah battery for the S4 , and from what I've heard another one even bigger than that
[Galaxy S 4 Accessories] nemesis93:
1 hour of screen time is quite a bit. My battery lasts me about 4 hours screen on time. 5 hours would be perfect.
[Galaxy S 4 Accessories] niv3d:
Well I wouldn't have to buy an extended case or cover for that bulky 7500mah battery. The 3000mah fits in the original cover :) I'd rather keep the phone the size it is. I left the note 2 for the s4 for that exact reason... The s4 feels WORLDS better in one hand than the note 2 ever did
[Galaxy S 4 Accessories] mjs2011:

One day 5 hours standby on batter with 4 hours of screen time. I'm now at 37% for my i think third or fourth charge cycle. I charged my phone to full and was downloading a lot of apps on it while playing with dsploit and zanti. I'm guessing that ran the battery down a lot faster than normal.

As long as it doesn't fry the charger it should be good. The current rating on chargers is the maximum amount it can handle supplying.

Most cell phones will only draw 1 amp max, but if you were to connect something else that draws more than the chargers rated output it will burn up the charger.
[Galaxy S 4 Accessories] paincorp:
It's rated for 2.1A and 1A, I had it plugged in to the 2.1A output.

Two options, your battery not really completely charged

Or something is eating your battery even when it's in standby

Or last resort, battery defective

I suggest, GSam battery monitor

It gives full picture, when tell you at what power was screen used

Plus it's barely using any power itself
[Galaxy S 4 Accessories] echsos:
I don't think it is because it hasn't fully charged; I've let it hit 100% and then left it on for a couple hours before. My only guess then was that the phone hasn't calibrated the battery yet. I'll give it another week or two to see how my times average out. If they don't get better I'll call ZL about it.
