just got mine and plugged it in with the phone off; I assume thats the best way to charge it up..
and, as others have indicated, the case is nice, and the phone is about the size it would be with an Otterbox Defender case on it!

Maybe thickness wise the phone is near the defender, but it definitely feels smaller since the sides go inward.

Anyone know of a belt clip to hold the zerolemon and its back? I decided to ditch the otterbox. Too bulky.

Is there any charger/dock that I can use to charge the zl separately without having to modify it while im running the stock battery on my phone?

so, charged this thing up for 15 hours, and started it up this morning; within 30 minutes I have gone to 96% from 100...is something wrong with my battery, or does it take a complete charge/discharge cycle to calibrate itself?
I did wipe my phone and restore a back up,plus do all the normal email checking and stuff, but I was under the impression it wouldnt budge off 100% for at least a few hours..

thanks!

Let it ride man. Needs time to figure out. My battery dies this to but at the end of the day I won't have used more than 30%

Everyone who thinks there is something with the battery, just give it a few cycles. Most people claim that the battery will discharge a few % in a matter of minutes but would stay at let's say 70% for hours. Your phone can only guess the % so you're best off turning off your phone percentage and quit worrying about it. The battery is 3x the size, it's going to last you for a while.

It's weird, I'm getting same or more usage time with Mugen's 6400mAh battery. Looks like Zero Lemon puts some extra mAh on their label
The guy from PocketNow gets 4 days on it - read the review


Then you got a bad one or you're doing something wrong. I tested the ZL outside the phone, on a stand-alone discharge tester. It came it slightly above the sticker rating. It's the first extended battery I've ever tested that does. I have not tested Mugen or Sedio, I find them very overpriced. In the phone, I do get 3x the life of my stock battery. Ignore the stupid android % indicator. It's a guess. The only test that matters is 100% to turn off time in a phone, or a real external discharge test.

OK, so YOU have been a member of XDA community since 2012 and have 43 posts in here. EVERY SINGLE post promoting MUGEN battery.

I'm not trying to be XDA "police", we got our own distinguish admins and real cops on this forum :p If you want to promote YOUR battery, I could care less. But if you come here to trash the competition with false accusation - that is NOT COOL!!! Just ask a few other vendors who no longer members of this forum.

He obviously gets paid by Mugen or work for them. Look at his previous posts, within a month he posted all the links directing people to get to mugen site. Admin, ban his account please? i signed up just to write this

Another reason not to buy overpriced, fake mah mugen batteries

I have both the Mugen and the ZeroLemon and they are both fine batteries that in my experience live up to their claims.

With the Mugen(6400mAh) I get double the stock battery(3100mAh) life and with the ZL(9100mAh) I get triple the stock battery life.

One is not better than or worse than the other. The ZeroLemon simply has more juice, that is the difference. Oh and the price. Mugen being too high probably.

Just my opinion after owning and using both. :)

ZL is clearly better in every persepctive except for ths case..

I personally cannot justify Mugen's pricing, they are aiming higher profit margin than apple

Oh well, some people like to spend money for nothing, so be it

I had few cycles so far from my ZL battery, and i could not be happier with battery life


Note: Phone is no stock/not rooted. Power saving on ocassionally


Typical battery life from my stock battery was 1~2 days with 6~8 hours of screen time


Zero Lemon

First charge: screen brightness auto / power saving / mostly wifi

over 2 days and half use with 24+ screen on time 8% battery left


Second charge: brightness auto / wifi and lte

over 3 days use with 20+ screen on time with some juice left


Since then i am using full screen brightness with lte because i cannot drain this thing

with 100% brightness with everything on i get over 16 hours of screen time, which is amazing


This is the first time that i do not worry about battery for my "smart" phone absolutely

Yeah, don't listen to anyone saying bad things about the zerolemon battery. I'm a moderate/heavy user. I use my phone for navigation/music (always simultaneously when driving to new locations in an area I just moved) a lot, have bluetooth always on with my pebble or for headphones when needed, gmail sync, never on wifi unless I'm browsing at home (i know wifi on even idle apparently saves battery but I'm too lazy to do that every time, lol), location settings always on except gps (until necessary for navigation), auto screen brightness, sms popup with fast blink setting, Advanced Task Killer Free without killing apps that keep opening up and using it frequently to close apps that I no longer am using (killing system/constant open apps like maps will drain your batter because these apps will fight you and keep restarting). I text a good amount, and my calls vary from minutes to an hour on and off but not too often compared to texting. I also live in a very excellent 4G LTE area with 5 bars always.

I am on perseus 35 kernel with CleanRom Ace 4.5 (smoothest for me so far - might try 4.9 soon because CleanRom doesn't disappoint).

I've officially been off the charger for 55 hours with all of the above having been done at many points in that time period and my phone is still at 77%.

This battery can easily go for 5-6 days if you use it the way I do. This is also on the first 12 hour charge...so if everyone claims that it gets better with the discharging of 5 cycles...I might be able to even push 7 days. I'll keep you all updated...but a battery that can last a week? That's insanely awesome in my book. If you guys have any questions or need advice on apps or kernel settings let me know.

Perseus Kernel 35: CPU:1400/300 (for some reason keeping it at 300 avoids freezes of any kind- odd but true- this is also what you need to do if you guys use the big 4G/5G profiles so the phone won't ever bootloop). GPU: 640. I/O Scheduler: Zen/Zen. LED Settings: Fast blinking, No fade. Audio: Headphone Boost at 63 (57 standard). Btw, even if you put the cpu max at 1600 or 1800 - the battery won't be that much affected...I've tried it. The kernel/rom combo is that good.

If anyone has better/more realistic tips for performance and battery life, feel free to share/add to this. Sorry for the super long post. Thank you :)

Mugen and Zerolemon both make awesome batteries, Mugen just charges more money.

That's their prerogative. Doesn't mean anything is wrong with their battery, the Mugen simply doesn't have as much value for your dollar. I personally don't worry about value when buying gadgets. I worry about fun and the Mugen and Zerolemon have both been fun to use. :)

    lol i see so many people saying the claims 9300 mah is way off a few getting only 2 days.. and you guys all screamed at me for giving it a bad review.. a i told you so is what i should be saying.. this thing is horrible.. the case if you drop it will likely fall off causing phone damage.. now we have to wait for them to make one a hard case.. of course more money for it..

    ive had mine idle no screen on 3 days tops.. i got that with the stock battery..

    so the claims of 3 times more capacity is just another lie.. one guy said his drops 1% per hour mine did that every 30 minutes.......


    no more extended batteries for any of my phones there all made in china china has no standards like the us does.. samsung isnt china and samsung makes the best stuff thats why the stock battery lasts 3 days and barely goes down....... rip me all you want... all yall got pissed at me lol now im the one laughing

    Yeah mate, you're definitely the one laughing, this battery isn't the reason why people only getting 1-2 days of use are getting 15-20 hours of screen on time.
    There aren't other users saying they're getting exactly 3x the battery life with this battery
    In fact, here are some quotes to show you the usage some people are getting:
    For me, I truly am getting 3x the usage out of the ZL battery compared to the stock battery, so it is performing exactly as advertised.

    I've been trying to use the last 20 percent for over a day now.

    Bought one last week had it in for 2 days ish now and I'm only at 70% its really crazy =D

    Not sure if the battery indicator is reliable. I was at 4 percent for almost six hours then another 4 hours before the phone finally shut down.

    so the battery is settling into its own now. i went to bed last night after a day and a half off the charger with 41%...woke up with 41%. i just think that the phones are not able to correctly gauge the percentage of battery with these huge batteries

    id give it a few more charge cycles, my precentage dropped like that too but then hovered at 74% for like 8 hours then dropped again and hovered at 56% for the night, the phone isnt calibrated yet.

    First discharge test complete. 9347mAh.

    Test was done with an R/C battery analyzer using a 1Amp discharge rate with 2.9V as the cutoff voltage. I've used this unit and settings before using stock batteries from other phones as a control, it has always been consistent.

    Nice work ZL.

    16% 3days 5 hours and 11 hours screen time on my first charge...this is clearly the extended battery to get.


    Oh, and in regards to the case you say will fall off straight away:
    I am not sure why Locust34 states the case is loose. Mine is super tight.

    Mine is a snug fit also...


    Just because you're not getting what you hoped for from the battery doesn't mean it's not doing its job.
    It's also entirely possible that you got a dud, you can contact zerolemon and see what they do about it.
    Also, the STOCK battery that comes with the phone is also assembled in china.

    Wow, what a beast! Finally, after years of begging, someone finally makes a non rectangular battery! I may have to buy one for that reason alone.

    not till 2 days after.. see i look at it this way.. you make a promiss you keep it... they should have shipped 1 week before the 15th then it would be on time.. just for failing a promiss they should give a small discount for 24 hours... also these things the way they respond in their emails sound chinese.. that means the battery is made in china we all know extended batteries from china like the 3 i bought 2 months ago all failed within a month... so i hope they wont cut and run or say oh i pay return shipping... no no im not the one that will loose you pay return shipping or reimburse me.. so i hope it holds up to its claims that it is 9300 mah because i will test it

    they cant advertise 1 day shipping then you pay for it and it come next week thats false advertising.. i paid 43 total with 1 day shipping..

    if mine dosnet show up tomorrow or the next day i will demand my 4 dollars back....

    thats 2 red flags on this company so far if i dont get it in 1 day.. 3rd will be it only holds so much charge then fails to live up to its mah

    amazon.com sucks.. i talked to a live agent though a chat window.. on why they show the product and why they have 1 day shipping

    first it sounded like an indian dude not an american who understood a simple English sentence i wrote..
    second they said they get then from a warehouse from zerolemon... and i said so why did i pay 4 bucks to get my product tomorrow when you dont even have it in stock .... got no answer..... then i notice 1.00 check card authroization on my card.. for singing up to the dumb club.. which i intend to cancel.. and they dont tell you they do. that..

    dont shop at amazon they are big ripp offs.. just read there own forum lots of complaints.. so when my battery comes monday i will demand my 4 bucks back seeing how they had free ship anyway and 1 day which was the only choices i had...

    wow customer service nowadays is the worst ive seen.. way back when you got answeres now they just tell you to screw off.

    great for some others they just dont care.... there is no other website to get this from zerolemon said they only go with amazon.....

    i just got the 4 bucks waived they even told me 2 days or more because its not in their stock..

    and the 1 dollar charge its to see if you have an good credit card that works.. i told them hey i buy off you all year long how does it not work... it would have been nice to know that before you charged it no where does it state it would have been charged 1 dollar...

    again they dont inform you of stuff.... another situation i went with a gameservers.com they screwed me over last week paid them money set up the server server went offline for a week they refused to email me back and explain.. i asked for a refund.. withing 30 seconds i got an email hmmmm...

    businesses now dont care about us they have so much broad customers that the 1 customer they can tell screww off .. back in the day it was yes sir and no problem and never any problems.. lately companies dont give a crap.. take gas they just finally said it oh we can charge what we want regardless of demand and supply... we the people have no more power over anything... it has to change...

    sorry for spouting off.. but im tired of being stepped on by companies.. this is the 4th time in 2 weeks..

    Wow, you are the most ignorant, dim-witted, impatient individual I have ever seen. It was stated MULTIPLE times that the battery wouldn't even be in stock till the 19th and yet you expect Zerolemon and Amazon to cater to you and you alone by shipping it to your door (days before it would even be available to the public) in 1 day because fast shipping was offered on a product that wouldn't even be in stock for a couple more days? You think you're some special person that has to receive everything first? Their PROMISE was to have it available for shipping on the 19th. And then you come up with some absurd assumptions that everyone you "talk" to at Amazon are foreign which just makes you look like an even bigger ignorant fool. You sound like some uneducated schmuck with only half a brain with the way EVERY one of your posts have been typed.

    How about you step off your high horse and learn that the world doesn't revolve around you. If I owned a business and you were my customer; I would have told you a long time ago that you could take your business elsewhere because of how rude and ignorant you are. You act like businesses are just robots that are supposed to do as you say but in reality, they're formed from groups of human beings that can pick and choose who they sell to.

    If I were Zerolemon, I would have just cancelled your order and refunded all your money and sent an email stating that you were no longer welcome to purchase from my company as that would be my right; you want to be singled out because you think you're special then you would get singled out.

    Grow up.

    Could you post some pictures of the case and comment on the feel please? Thanks

    Holding it seems great, if you put tension on the case like you are going to remove it, it is more flexible than id like. note however, i have no prior experience with TPU cases, or other cell cases..

    if i even get exactly 2x the battery life, i would be more than happy. im loving the fact its not a 'hump' on the back. :good:

    It looks to me like their only mistake so far is in answering people's queries about when it might be available. Had they simply refused to give dates, people would still be anxiously waiting.

    It's always amazing to me how people feel like they are owed a product on a given date. If the date passes, they feel wronged and get angry. I could understand if the company had accepted their money already, but in this case nobody has paid anything at all. Yet still, people feel entitled and get angry at the company when their idle hopes aren't fulfilled. It seems like a lot of people need to pull up their big boy (girl) pants and learn that the rest of the world doesn't exist merely to cater to them.
