Zerolemon 3000mah batteries

Are there any real life time tests on how these batteries compare to the stock 2600mah samsung stock battery?

How much longer to these batteries last compared to the stock using moderate usage????

right now I get with moderate usage with the stock battery maybe 10 hours and im at 10%
[Galaxy S 4 Accessories] rhd-android:
They last ((3000-2600)/2600)*100 percent longer.

That's the only way to answer your question. Unless they are lying about the capacity (ZL isn't), this is simply a matter of comparing one number, to another, and figuring out the difference.

I've never understood this question. I'm not picking on you - it comes up a lot. But it's like asking "Is a 6 foot tall man really any taller than a man who is 5'8, and if so, how much taller is he really?"

4 inches. Exactly 4 inches. It's not subjective.
[Galaxy S 4 Accessories] redrover69:
Understood

basically then in theory the 3000mah battery should last 13.333% more than the stock battery...

hmmmm

Im just trying to figure out how to keep my phone running all day from 730am-1amish Right now my phone lasts until maybe 6pm and its at about 20% without a charge.

I dont want one of those big batteries like the 7500mah with the bigger case...
[Galaxy S 4 Accessories] hexitnow:
Do you have something in the background constantly running thats draining the battery? Something waking your phone? With the stock battery ive gotten nearly a day and a half with 6 hours screen on time. And thats using a stock rom. I would imagine if I was running a custom rom I couldve got more out of it.

Hit thanks if I helped you out. Doing a little bit of reading goes a long way. Sent via tapatalk.
[Galaxy S 4 Accessories] redrover69:
I get tons of text messages all day long. Cant help that.

I have customers and vendors as well as friends texting me all day long!

To save me the time in searching how can I find exactly what is running all the time that might be killing my battery???

I hold down the home button...and hit the pie lower left side then ram and free up the ram all the time. on the left side it says active apps and I try to keep that at a minimum.

Thanks
[Galaxy S 4 Accessories] rhd-android:
A good solution, for me at least, was a QI inductive charger.

It's a pain to plug your phone into, and then disconnect it from micro USB constantly, particularly if you're using your phone throughout the day. However, it's a non issue to just set your phone down on a QI charge pad, presuming you would otherwise be setting it down on a desk / table / surface somewhere anyway. You don't really have to alter any behavior, and you end up with a constantly charging phone, except for during the time when you're actually holding and using it.

QI receiver plus charging pad come in at under $40 total.
[Galaxy S 4 Accessories] Aitch:
I'm getting less than 4 hours screen-on time on the stock battery, with brightness at about 50% - are you using auto-brightness to get 6 hours?
[Galaxy S 4 Accessories] redrover69:
The problem with the Qi like you said its on a pad. when you need to use it..its constant on off the pad...I dont think thats so good for the battery.

I tried it. I returned the charger. The car charger I had was horrible. The samsung stock one.

The one thing I can say (please no bashing) the iphone car charger/charging system is awesome. Charges so fast...

Any other ideas are great!
[Galaxy S 4 Accessories] Aitch:
Would it be possible to squeeze/bend this QI receiver in to the ZeroLemon case?

Apparently it's only 0.5mm thick, but needs to touch a couple of contacts underneath the 7500mah battery...

http://www.ebay.co.uk/itm/New-Qi-Wi...ories_MobilePhoneChargers&hash=item53faab7045
[Galaxy S 4 Accessories] Snowdog7:
I thought I read earlier in this post that people have been able to use the QI receiver with the 7500mah battery. It even had a pic.

EDIT: This is from page 60 of this thread...
[Galaxy S 4 Accessories] Aitch:
Thanks dude, just what I needed to know!

A few more questions though if you don't mind:

Does the Qi cause a bulge on the back of the ZL case?

How many hours does it take to fully charge the 7500mah battery?

Does NFC still work okay?

Thanks man!

PS: FastTech is one of the coolest websites ever! Have you been having any problems getting stuff delivered lately as it seems a lot of people are complaining recently?
[Galaxy S 4 Accessories] Aitch:
Thanks dude!

1) Does the bulge make it wobble around when it's set flat on a desk?

I've seen videos on YouTube of people peeling off the covering on the Black receiver to make it thinner (which apprently makes the NFC work better too) - does the White one have the same removable covering?

2) Do you leave it on the charger overnight? Does it get hot at all?

I just did a Google and found this excellent AnandTech article http://www.anandtech.com/show/7163/zerolemon-7500-mah-samsung-galaxy-s-4-extended-battery-review - if a 2A charger takes 7.5 hours then would I be right in guessing a 1A charger would take 15 hours? Or 30 hours if the receiver puts out only 500mA?

I've also read that to keep a Lion battery in good health, it's best to let the battery fall to less than 20% and then charge it up to 100% - with the ZL being so big, would it ever get to 100% with only an 8 hour overnight charge?

3) Sweet!
[Galaxy S 4 Accessories] ghettoc401:
1) Just tested it and it doesn't really create any wobble

2) I don't charge it overnight. The main reason why I bought the zerolemon is because I fall asleep in my bed while watching TV and forgot to charge my phone, so the ZL battery makes sure that when I wake up my phone is still useable throughout the day. I also got the wireless charger because its easy for me to drop my phone on the pad instead of rolling over and finding the cord to plug it in.

At 1amp, I would assume that the battery would take 15 hours to charge from 0% but then again, I've never tried it so I wouldn't know. My battery is at 67% now so it would take me two or three days before I could test that out haha. And even then, I don't think I could let my phone sit still for 15 hours.

As for the Li-Ion info, that is true, its best to charge it from 20% to 100% but it will take 2-3 years before you start to notice the effects of improperly charging it. I'll probably have the S5 or Nexus 5 in a year or two so I'm not worried about it.
[Galaxy S 4 Accessories] ghettoc401:
I haven't seen too many people that had a high amount of talk time with the battery (just screen time) so I figured I'd post my best results with the battery so far. The pictures tell the story but I did a lot of music streaming through bluetooth in my car with Google Music. I've had the battery for 2 months and love it.
[Galaxy S 4 Accessories] Aitch:
Cool!

4) How do you rate the case? Do you think it will last a long time? Does it fit perfectly and have accurately cut holes for everything? How grippy does it feel in the hand?

5) The ZL is about 3 times heavier than stock, do you feel the weight while gaming or making calls?

6) You're right about it lasting years lol, but that would be if ZL uses good quality cells which can go hundreds of cycles. Does ZL use cheap cells which is why they only offer a 6 month warranty?

Thanks again for your help dude!
[Galaxy S 4 Accessories] ghettoc401:
4) I'd rate the case a 6/10 honestly. I don't really like it, but I use it because that's the only thing that will fit with the extended battery. It has accurate cut holes for everything so that's not a problem. For me, the issue is it doesn't make you feel that if you dropped the phone that it would do much to protect it. This is a problem because the phone is ~2-3x heavier so it falls with more force. Naturally you would want a case made out of better material to protect it.

5) You definitely notice the additional weight when you first use the battery, but after a week you get used to it. If you ever switch back to the stock battery you'll notice the phone feels like a paperweight and "cheap". All psychological though :p

6) I don't know what kind of cells they use but I do know they have received great reviews on their batteries and are a reputable brand. My buddy has had a ZL battery for his S3 for about 9 months now and he hasn't had any issues.
[Galaxy S 4 Accessories] Aitch:
Is it really weak and liable to break? It looks like it's made of some kind of rubber material. does it offer atleast a little protection? Also, does the case slip in and out of pockets easily, or is it too "sticky"?

Is it heavy enough to cause your arm to get tired after a long phonecall?

Yes everybody raved about the S3 version, but the S4 seems to have had quite a few complaints!

7) Have you had any reduction in signal quality?

8) Have you had any reduction in sound quality?

9) Does the case impair the amount of light the camera receives?

I was going to wait and see if ZL bring out an updated version but dangit, you're making me think I should go and buy one now! Does ZL ever have a sale lol...

You've also "forced" me to look at buying buying a wireless charger too - will this one be okay? http://www.ebay.co.uk/itm/Qi-Wirele...S_Cell_Phone_PDA_Chargers&hash=item2a31dd152c

10) I'm guessing a white pad would make it easier to see how well the phone is placed on it - does it matter if you don't sit it perfectly in line?
[Galaxy S 4 Accessories] ghettoc401:
The phone feels heavier but it has never caused my arm to get tired while on a call.

7) I haven't noticed any reduction in signal quality

8) The case covers up the back speaker so the sound is not as loud coming out from it, but its not a dealbreaker. If I'm downstairs in my house, I can still hear my phone when its ringing upstairs

9) Not to my knowledge. The cutouts around the camera are appropriately sized so I wouldn't see why it would cause issues with light coming to the sensor.

10) That wireless receiver and pad that you linked to is perfect. Thats the exact same receiver I have and the pad is similar to the one that I have. The phone pops up with a dialog box to let you know when it is within range of the wireless charger, and the pad has a led on it that changes color when its charging. So you'll always know when its placed on there correctly.
[Galaxy S 4 Accessories] Aitch:
Well that does it, I better go buy a ZL battery and Wireless Kit!

Do you know of any app that can monitor the amount of power the phone receives when its charging? I'd like to confirm its really getting 1A as most of these things seem to be rated 500mA-1000mA so might actually be charging at the lower level.

Thanks again for all your help dude, although my wallet is going to be a little lighter now lol!
[Galaxy S 4 Accessories] ghettoc401:
I use Galaxy Charger Current Lite to check the current rate that it's charging.

Also no problem on the help. No one had posted S4 + ZL battery wireless charging info at the time I bought everything, so I kind of just pulled the trigger and hoped it worked. Glad I could help clear things up :good:
[Galaxy S 4 Accessories] Aitch:
Excellent app! You're a gold-mine of info dude!

I take it you've checked your wireless setup and it's showing the full 1A?

I had a play with it just now, I plugged my Samsung charger in which is rated at 2A and it's showing 1200mA - then I dug out an old HTC charger rated at 1A and it still showed 1200mA?

Does that mean the battery has a maximum input of 1.2A or does it mean both Samsung and HTC are lying about the rating of their chargers lol? Wait, maybe it means the app has a bug?

The world needs more first adopters like you, or maybe you should be called crazy gamblers who throw caution to the wind lol!

Please do keep posting about any other triggers that you pull! :highfive:
[Galaxy S 4 Accessories] ghettoc401:
It may be that the app is not reading the current right. I noticed that sometimes you have to leave it on the charger for 10 minutes or so to get the correct voltage. It may be that the phone does not pull the full 1amp initially or it may be that the app needs some time to correctly read the current that's being pulled. I'm not an expert on the matter and I haven't looked into it so I don't know which is the case. But my guess would be that the app is not reading it correctly.

I think my wallet disagrees with you. I don't need to pull the trigger on any more purchases lol.
[Galaxy S 4 Accessories] Crauze:
The 7500mAh battery takes me around 7-8 hours to fully charge it using original cable and charger

NFC still works without any problems

The ZeroLemon case has a flat back so it won't wobble on the desk

Sometimes I charge it during the day or at night depends on the percentage of battery left, the battery may get a bit warm while charging but all battery does the same

I let the battery go down to 1-2% before charging it to full, 8 hours charging from 1-2% to 100% will be enough time if you're using original cable and charger

The case feels great in your hands, it doesn't slip and doesn't show up fingerprints, the holes are accurately cut and fits on the phone perfectly

But I would suggest getting the Black case as there's complaints of the White case showing dirts on it and hard to remove it

The phone will feel abit more heavier but I like it since it puts more weight on it so less chance of me dropping, but you will get used to it

Depends, but it does so I normally use earphones with mic when answering phone calls

I get the same signal strength as using the stock back case, just make sure you use the latest modem

There's holes on the bottom of the case for the sound to come through so it shouldn't reduce the sound quality
[Galaxy S 4 Accessories] nuscape:
Hi,

I just bought ZL 7500mAh as well but I noticed that the battery graph is showing ups and downs chart with some mini spikes, refer to attached screen shot. My understanding the graph will only go down unless it is charging but I didn't plug it to charge at all. Any idea why?
[Galaxy S 4 Accessories] Aitch:
I'm beginning to think this app might be a little dubious! Have you ever seen it show a current other than 300, 600 and 1200mA?

It might be simply detecting whether it has AC input or USP input, so just shows 1200 or 600 respectively? Do you know for sure that it works correctly?

Lol my wallet has never agreed with me!

I still haven't received mine yet. Did you order from Amazon, how long did it take for yours to arrive?

---------- Post added at 07:50 PM ---------- Previous post was at 07:50 PM ----------

Is it a good idea to let it go down that low? I thought LIons work best being charged from 20% to 80%?

---------- Post added at 07:51 PM ---------- Previous post was at 07:50 PM ----------

Good question dude. Maybe it will settle down after being charged/discharged a few times?
[Galaxy S 4 Accessories] Crauze:
Follow this guide to find out your real charging current

I'm in the UK and ordered mine via Amazon, it came two days after

Well according to ZeroLemon manual, you have to leave it to 1-2% before charge
[Galaxy S 4 Accessories] echsos:
The only downfall of this battery that I've noticed is the impact on signal and the sound gets a bit muffled. I live in an area where I get 2 bars with stock battery and the extended battery definitely covers up the signal a bit (i get 1 or none now). The sound gets a bit muffled but a quick fix appears to be using the electrical tape to make space for the battery as someone posted earlier on in the thread. The battery is lacking a good rugged case for it which really grinds my gears since I prefer to have a rugged case on my phones as I like to workout and go camping with them. ZeroLemon has promised a rugged case for the phone but I've been following their page on facebook and they went from "Oh we'll have these out by mid August" to "No later than 30th of August" to "Hey, i'm the owner of this wireless store in charge of selling the batteries and I just ordered them so they're on the way and they'll be here by next week (that was 2 weeks ago)." Now, the seller and ZeroLemon both abandoned the page with no word from either so I guess we'll see if this rugged case comes out before the end of the year lol. Otherwise, not a bad battery at all if you live in an area with good to strong reception.
[Galaxy S 4 Accessories] Aitch:
Thanks dude, unfortunately I'm not rooted. Is there another way to find out?

WTF! I'm still waiting for mine! Are you on Amazon Prime?

Interesting. Maybe they are using a modified version of LiIon chemistry? Or do they deliberately want their batteries to have shorter lifespan, so people need to keep buying replacements lol.

I'm in the same boat with you. I think these people run with no radios on all day or something. I never get that kind of battery life. Just like people with the Nex and Rezound would say "omg, I get x hours out of mine". I was always, and still am, 1-2 hours less than that of screen on.

Also, I'm not complaining about my battery life, I do get about 3 1/2 on an average day, but I have just never seen 5-6 hr of screen on. Most I think I have ever gotten is like 4 1/4.

I am very excited about the rugged case. There are a few things that I need to know before ordering them and it would be great if someone who gets theirs can help me get these questions answered.

How does the outside feel?

Can the headphone port fit large headphone jacks such as Shure?

How much larger is it compared to the TPU case? Can someone please post a side by side comparison shot?

Do you think that the screen can now survive a several foot drop? The screen is the most breakable thing on the S4.

Is the case itself heavier?

How does the screen protector feel and look, does it make the screen less clear and does it feel bad swiping?

How hard is it to press the buttons?

I can say I absolutely like this rugged case for S4. This case doesn't add bulkiness to your phone. Its made out of a hard rubbery material but its still flexible . It has these grips/bumps on the side that protects the phone if dropped and allows you to get a better grip of your phone. All my buttons, ports, camera and microphone have openings for easy access. my case doesn't get dirty. Since the case is hard for protection but still flexible it makes it easy to remove off your phone and put it back on without struggles. I have dropped my phone in different floors and it has protected my phone. Those ridges on the side do work. Love it protection without the ugly and bulky look.
