I just got the 2pack 3000mah and charger from bastex off of ebay. Do I really need to charge these 12 hours before using?
[Galaxy S 4 Accessories] Firepac:
So is the signal problem caused by the actual battery or the case?
[Galaxy S 4 Accessories] Eris _2.1_2010:
+1 I have two sitting at home still in the packaging. Wasn't able to get home last weekend, so maybe I'll get to try them this weekend.

Has anyone tried this with the 3000 mah Zero Lemon? http://www.youtube.com/watch?v=Tk6mc1RPb3U

I'm thinking about pulling the trigger and getting one.
[Galaxy S 4 Accessories] nuscape:
No black color?
[Galaxy S 4 Accessories] guapinoy:
No black just white. I just got the case. The Zero Lemon 3000 fits but barely and it causes creaking in the case. Gonna try it with the stock for a while to see the battery life.

Fwiw, here's the measured calibration I'm experiencing. And this is after about 10 to 12 cycles.

Does anybody know a good external (travel) charger like the one from zerolemon which is available in europe?

1A or 2A charging speed would be perfect

My 7500mah ZeroLemon won't hold a charge anymore. I sent it back for a warranty exchange.
[Galaxy S 4 Accessories] Eris _2.1_2010:
So far I'm happy with my two 3000mah batteries. Just breaking them in now. They do fit pretty snuggly and the battery door is a little harder to get on but it's nothing when I put my Spigen Neo Hybrid case back on then I don't notice the slight bulge anymore.

How many hours were you getting from the ZeroLemon and how many are you getting now from the Hyperion? Does the ZeroLemon case fit with Hyperion battery?

Did you follow the ZeroLemon recommended guidelines on charging it initially? I think they may be wrong about the advice they give out?
[Galaxy S 4 Accessories] milkit18:
The Hyperion 7500 mah fits the zerolemon rugged case. FYI.

Fwiw, 3k Zerolemon lemon after about 3-4 weeks. Before I was getting about 3 - 3.25 hours of screen on. Now I get between 4 - 4.5. For this specific cycle I'm now at 2% with 4:10 screen on, 20 minutes worth of phone calls, and 2 or so hours of music streaming.

Also, just to let whomever know, I have a wireless charing receiver with NFC in use with this battery. My setup is in the wireless charging thread. Just in case anyone was iffy because of the battery not having nfc. Or if you are afraid you will lose wireless charging. I have retained all the original functionality of the phone just by using a specific receiver with NFC built in.
[Galaxy S 4 Accessories] rhd-android:
Mind sharing what receiver you are using with NFC built in? Forum search feature seems to be down.
[Galaxy S 4 Accessories] 1454:
This is the link to ebay where I bought the receiver. And below that is a link to the post on xda. With this I also haven't found any cases I can't use. I have 3 cases I couldn't use with the oem wireless charging back, but with this I can use all of my cases. The back does fit a little tight with both. The receiver and extended battery though. If the first link doesn't work, the actual ebay only link is in the second link.

Can share your battery performance?
[Galaxy S 4 Accessories] Adchen:
Allright so I've been using the 7500mAh for about a month now and I'm very pleased with its performance. I've been getting around 10 hours of screen on-time on a full charge.

However, the TPU-case has been bugging me a lot because you need to press the power and volume buttons really hard and there's not much of a tactile feedback.

So I took a very sharp knife and made an incision where the red lines are on the image, and the results are great. Now it's pretty much as easy to press as without a case on and the clicky tactile feedback is finally back :)
[Galaxy S 4 Accessories] simichoil:

You only need to cut one side of the buttons, preferably the side closest to the front. Just remember to use something really sharp like a scalpel.

I love my 7500mAh ZeroLemon !

In a few words; I love my ZeroLemon !

I ordered my ZeroLemon 7500mAh from Amazon.co.uk, as Amazon Germany didnt ship to my location. (i'm located right between Germany and the UK and A doesn't have a store in the Netherlands.

The battery arrived day before yesterday. Following the instructions i charged it for 12 hours and started using it since yesterday morning. It's now on its first discharge cycle.

I do some gaming/browsing/play store, use Waze for trafficking (screen-on all the way), and read the news a bunch of times a day. So moderate to heavy use i guess. Last night my battery was still at 70%.

Right now it's still at 60% after 1d 2h 9m including three 45 min. drives with Waze+screen-on all the time !

Before i got this little monster, ehm, emon, i was always limiting my screen-on time and tweaking the heck out of my S4 (S2 with Sammy extended battery before that), but now i really don't care about running out of juice before i get home in the evening.

The S4 looks bulky with the new case, but ill take the extra juice over that any time.

If anyone cares ('like' this post ! :good:) i'll post some screenshots, and keep the thread updated.

ps. yeah, since about a week my username sucks :p

Update 1: it's on 35% after 2d 16h 16m right now.

Heck, i even tried out some live wallpepers (usually a real battery killer).

Winter is coming, so i got the pro version of snowfall ( Christmas trees, snowfall, balls, parallax scrolling background, yay! )

Update 2: After 4d 1h 14m juice was about to run out (2%) so the battery is not bad at all and much better than what i expected !

(i noticed there's a one minute difference in the second picture, I'm still pulling my hair out on that one :silly: )

xProDock active car-dock works with 7400mA battery

All, a ton of people have asked if the ZeroLemon 7400mA battery is compatible with our xProDock active car-dock. The answer is "yes" as the "feet" expands to 21 mm (revised from 19 mm) and the thickness of an S4 with a zeroLemon is 17mm. The new rugged cased talked about should fit as well but we'll by one as it becomes available.

However, "fitting" into the Dock is only one aspect. Equally important is that the vehicle Dock you pick does not vibrate with the heavy combination of the S3 and the 7400mA battery and from personal testing I can confirm it's "rock solid", even to the point that you can install and use an App like "Road Voyager" and use your S4 as a really good dash cam. From my tests it never "slumped down" either. If you don't want to use the suction cup, just get the "AMPS plate" and use the xPro together with the very good ProClip vehicle specific mounts or KUDA leather Mounts.

Finally, keep in mind that when picking a vehicle mount it should trigger "DockMode" so you have a dedicated "Car home screen", like the iBOLT Dock'n Drive, the equally excellent CarHome Ultra or Ulysse Speedomter for example. Also, use a cable like the "Dock'n Play" so the sound from Apps are coming through the microUSB to a "split aux/USB" for routing of App sound to the car-stereo (if you have a 3.5 mm aux-in). The xProDock can be found on Amazon for example. Have fun!

Looks like Amazon currently has the prices at 8.99 and 39.99 ... are these the best batteries for the s4 for the price? Or are there other ones I should be looking at? I think I'll by the 3000mah one... just as a spare for when I am traveling and using my phone a lot.

[Galaxy S 4 Accessories] blackknightavalon:
Hyperion has a 7500mAh battery for five bucks cheaper than ZeroLemon, and it lasts just as long. Anker recently released a battery/case combo rated at a total of 7600mAh that's pretty cheap, too.
[Galaxy S 4 Accessories] SilentEYE:
What was your screen on time?

I noticed that you have bad signal strength. maybe you can switch to a 2G Network, at least when your screen is off, to achive a better battery life.
[Galaxy S 4 Accessories] sgs2.5:
Wouldn't screen on time be 61% of total battery juice or 61% of 4 days ? See the attached pictures in my original post.

Thanks btw,, I'll look into my signal strength, although I'm not complaining about that, I didn't notice bad signal strength really.

update: 2013-11-17 : Right now I'm at 34% after 5d 0h 16m (average to low use) 50% screen on. (detail for screen on shows 7h 37m 22s)

I'll probably have to recharge tomorrow night (3rd time).

ZeroLemon 7500mAh S4

OK, today i had to place a bunch of calls, so instead of completely draining the battery I had to charge before running out of juice.

So I got 5d 19h 56m out of it this time with 8% of juice left.

As you can see from the screengrab from 15% downhill the juice seems to run out pretty fast.

[Galaxy S 4 Accessories] iridaki:
I got this battery, as well as the rugged case, on Wednesday evening, put in on the charger immediately and unplugged it 12 hours later.

So far it's going really great!

Stock Samsung battery usually got me through 14-16 hours with approximately 3-4 hours screen on.

This battery seems to be able to give me twice that and then some!

(In the screenshots you can see that my phone was briefly charging tonight, because I did a software update and I transfered a few files to my PC.)

Also the rugged case is truly amazing! Got the pink/purple one, the quality and the detail is impressive. Only problem is that the proximity sensor is a hit and miss with it on, probably due to the pink inner layer. I guess with the black case that won't be an issue.

not bad but you can surely have much more days if you would check your signal problems. why not switching to 2G after 5 minutes if your screen is off?

Did you use auto brightness?
[Galaxy S 4 Accessories] iridaki:
The screen on time is the key here. As you posted above, you achieved 9 hours. I achieved 8.5 (probably more as it stayed in 1% for quite a while, plus the phone spent 30 minutes in recovery doing a nandroid, which is not reflected in the stats). You did it in 6 days, I did it in 2. I just use my phone quite a lot is all! :D

I am on 3, a UK network that does not support 2G at all.

Yes I have auto-brightness on but when I watch Netflix, I usually turn it up to maximum.

I'm on the second cycle now, let's see! :)

Not even 1 FULL day with 7500 mAh

Hello all, I am genuinely surprised to see some people claim over 5 days of usage. As I have tried a few extended batteries for a few different android phones, I know there is going to be some variability in the longevity of the battery bar. However, a few days is a big difference to 12 hours max.

Any suggestions or tips to achieve optimal performance, PLEASE DO inform me.

I'll admit I'm a novice when it comes to some of the more techie stuff but I am no novice to rooting/tinkering/figuring stuff out. I am capable and willing (to a certain extent) to try all possible suggestions.

If it makes any difference, my normal battery lasts 3-4 hours. I remember back when I had a rooted and ROM'd Droid Eris. It was probably some of the best battery life I've ever seen in any of my smartphones to date and that was back in 2010 at least.

Average Day of Usage:

Texting throughout the day.

Minimal phone calls

Streaming music on Slacker Radio for 1-2 hours (occasional)

GroupMe (Minimal Daily Usage - No constant sending/receiving messages)

Mobile Hotspot (while on charger | battery charges normally so I don't believe this affects the battery drain)

Facebook seems about the only constant running thing ( I say that because I get notifications from it quite often - hourly)

Verizon Galaxy S4 LTE

Hyperdrive Version 10.0.0

I keep data/bluetooth/Wi-fi/GPS/NFC/S Beam/ etc. off.

My display brightness is set to the absolute minimum with the occasional turning on of auto-brightness. No sync of any kind is turned on, I do it all manually.

There is a setting called Power Saving which I have on at all times. Not quite sure what exactly it does, I've only noticed that when my battery gets so low it puts my phone in a permanent state of low brightness (hard to see anything on the phone in the sunlight when this happens)

I've updated the ROM a few times while using this battery. So yes, I've started fresh a few times.

I have had this battery since July of this year, I am still within the 180 days.

I was quite satisfied with the battery as it lasted much longer than the original battery for me; however, after seeing claims of 2-5 days, I think I am missing out and possibly have received a bad battery.

As I said PLEASE give tips and any advice, that includes alternative ROM choices, I am now looking for a good 4.4 ROM at the moment anyway; however, I will settle for a 4.0 ROM that gives me 1 FULL day of usage if need be.

If I can help you to help me or anyone else in any further way don't hesitate to say so. ^_^

I have a zerolemon 7500 for a couple of months now wich get's 5 days and i will tell you the secret :)

You'll have to buy Android tuner and inside the app go to system tweaks and enable 'screen off battery savings'

This will disable wifi + mobile + gps when your screen is locked

-> without this setting i get about 2 days with my zerolemon 7500

-> with this setting enabled i get 4-6 days with the big battery depending on my use, when i am sleeping the phone uses less then 1%/hour

For me the only thing using all my battery was the mobile internet (3g/4g) but now that it is turned of when i lock my screen i get up to 6 days standby time

Other helpfull hints :

- disable media root scanner

if it uses to much battery in your battery stats

- limit background process for exhange services

- calibrate your battery

I hope this will help you get more standby time.

---------- Post added at 07:01 PM ---------- Previous post was at 06:49 PM ----------

Remember wifi is still on if you turn it off (at least it is that way in my phoenix 4.3 custom rom) ;)

Go to wifi / advanced settings

-> keep wifi on during sleep -> change to only when plugged in

-> always allow scan -> make sure you disable this

Now your wifi is really off if you don't use it :)

---------- Post added at 07:10 PM ---------- Previous post was at 07:01 PM ----------

mine (brightness) is set to auto +2 all the time

my power saving is also on all the time, this has options : enable/disable haptick feedback + screen power saving + cpu power saving

mine is set to enable haptick feedback, cpu & screen savings are set to on.

I have updated/installed many roms since i bought this zerolemon, Tamirda (developper Phoenix rom wich i advise as best rom) told me it is important to calibrate your battery after every install from a new rom.
[Galaxy S 4 Accessories] JohnnyB3777:
Strange, I've read in so many places where people say setting it to keep wifi on during sleep saves battery, never imagined how that could be the case. I guess now I see it wasn't exactly true lol.

Also, in this short time, I've taken the plunge to IOKP Rom http://xdaforums.com/showthread.php?t=2517360 it.s AOSP and for some reason the theme on the forum isn't on my phone, however, I didn't read through the forum thoroughly as I was switching ROMs in the middle of finals and presentations (yes, I could've waited but I got too excited about kitkat)

That being said, I no longer have a powersave feature (I've read that it's TouchWiz specific). I don't know if it's because the way that feature saves battery is that it keeps TouchWiz from doing too much and it's not needed in AOSP or if I'm missing out on more battery gain.

The killer:

I ROM'd my phone at 11:40 a.m starting with 83% battery (used the wrong gapps package, took a bit of searching in the​

thread to find the right one for kitkat)​

The ROM was FUNCTIONAL at 1:04 p.m. (presentation took up the majority of that time, that and downloading 86MB on a​

slow school network :D.​

My battery now, at 7:56 P.M. is on 67% reporting 7h 14m and 51s on battery )it was not charged during any of this time​

time nor connected via usb to any computers.​

This makes me think that perhaps Hyperdrive was eating a lot of my battery as well. Or either AOSP is just a beast for​

battery life. I kind of don't like the plainness though and I miss the notification bar toggles (it spoiled me lazy).​

I will stay on this ROM until about 12 PM tomorrow (another final at 1) and then I will give your suggestions a go (for comparison)

And then after about another 24 hours I'll try out the ROM you suggested. (I'll do the calibrations now as that may have a negative effect if I wait any longer)

Thank you again for you suggestions.

Here's hoping I can actually hold out long enough to compare anything lol. I may wake up and be on a new ROM, sleep-tinkering is real!

EDIT: the ROM didn't flash right on my device. I have none of the theming at all and many apps constantly force close. No one else in the thread seems to have the problem so I'll be flashing over to your suggested ROM much earlier than expected. OAN: Battery is at 89% after 7 hours. So even though the ROM didn't go Well I at least have it as a back up if I ever need the extra battery.

EDIT2: the Phoenix ROM is apparently for a different version of the s4. I have the Verizon s4 ( sch-i545 ) so I well be unable to try that ROM.
[Galaxy S 4 Accessories] Spazzzin:
is it worth it to invest in an extended battery or is it still somewhat experimental/needs work?
[Galaxy S 4 Accessories] contrinsan:
Do you mean manually or Is there an app wich can auto switch between 2g & 3g when screen is on/off ?
[Galaxy S 4 Accessories] SilentEYE:
@ contrinsan

it depends on your ROM. On touchwiz you do not have an option to automatically switch to 2G f.e. when your screen is off. On CM based roms this function is integrated or you can use apps like tasker, automate it pro, etc.
