Hello!
I bought this battery from eBay and it just arrived.
I know the first thing that anybody wants to know when they hears "extended battery" is how it looks...
So, here are some pictures
(YES, they are shot with an iPhone 4 and the phone is on an iPad... My brother has bitten the forbidden fruit!)

OK, after almost a full week with it, here are my observations:
1. The battery is indeed of extended capacity and the cells appear to hold the charge better than stock battery so far. I do not have the equipment to confirm that it is 2700 mAh as it is claimed, but there is no doubt that it is almost twice as lasting as stock battery.
I've been in between changing ROMs at this point, but I will upload screenshots of Battery Usage in the coming days. I've been able to stay away from charger for more than 50 hours, which is an immense improvement over stock battery.
2. Battery cover is of OK quality, feels a bit loose at times, but it is not falling out of its place. Of course, I haven't dropped the phone, so I can't guarantee on the durability. Certainly sub-par to OEM battery cover, but not bad either.
The kickstand is purely awesome! Phone stands on a perfect angle. I am concerned about its durability too though.
3. Here comes the tricky part:
The phone seems to be unable to display accurate readings of the battery.
It drains from 100% to 1% approximately the same way stock does and then I have to pull it an re-insert it and when the phone boots it displays 65%. Same way, every time it hits 1%, I have to do the same and the percentage rises.
I looked into /sys/class/power_supply and found a folder called semc_battery_data. I searched further and realised that the capacity (1500) and type (Li-Pol) are actually hardcoded on kernel level. HTC developers have already addressed similar issues on kernel level.
I talked to Bazoocase (the developer of the 0% battery issue work-around, so pretty much the expert on the Arc battery gauge!)
about it and he confirmed that this is really the case:
Bazoocaze said:
I had read the bq27520 datasheet, and indeed the fuel gauge must auto-detect and adjust it's parameters automagically from the battery usage, so you must let it charge from 0% to 100% and discharge from 100% to 0% a few times without using heavy consumption to let it learn the new battery impedance/capacity.
However, looking at the sony driver source (battery_chargalg.c, among others) it looks like Sony have hardcoded the battery capacity in code, and then this will explain your usage issue with the extended battery.
Searching deeper in the kernel sources I found the constant value that seems to represent the hardcoded battery capacity:
file: arch/arm/mach-msm/charger-anzu.c
Code:
struct device_data device_data = {
.limit_tbl = &limit_tbl,
.battery_capacity_mah = 1500,
.maximum_charging_current_ma = 1050,
};

He was kind enough to prepare a test kernel for me, with increased battery capacity, from 1500 to 2700, and I am testing it right now.
____________________
All in all, my personal opinion is that this battery is long-lasting and reliable, a huge improvement over stock.
Whoever wants the extra juice and is ready to compromise the thinness of the Arc, could go for it.
I will certainly keep using it, as it has freed me from the "looking for a power plug" plaque.
Even if the kernel patch turns out not to be working, inaccurate readings are not an issue, at least for me,
when I can safely go through the day without charging and can reach up to 2 days of battery life.
As far as my usage goes, I could get 18-20 hours average from stock battery, which is not bad at all,
since the easiest thing to do is plug your phone before you go to bed. However, I do appreciate not necessarily having to do that too.
I will keep this thread updated should I have further findings.

How much backup are you able to make out of it?
It being thicker looks like it'll handle better. Does it feel any easier to hold?

When it arrived, it had 8% battery in it, I drained it and that took approximately 6 hours (5 hours screen on, music, youtube, browsing, emails).
I plugged it in overnight and today when I woke up, took the phone off charger. It's been 3 hours and still @99%.
So far seems really good, but to be honest, I have to monitor battery life for 2-3 cycles before I can tell if it's that good.
I'll keep you posted.

If you are willing to contribute to testing batteries, thanks to Bazoocase, I have a kernel that allows the fuel gauge to detect true battery capacity.
My stock 1500 battery is detected as 1420 and the 2700 extended as 2600.
I am really interested to see how much is the real capacity of those 2430 batteries that maintain stock size. If they are for real, it would be a great improvement!
PM me if you are interested!

SUMMARY:
china1800, jindian1900 and andida1850 sold on ebay is a SCAM. The real capacity of these batteries is less then 1300mAH. Instead, for the same $10 on ebay you can get two spare batteries at roughly the same capacity and a charger. Capacity of newly available on ebay extended size batteries for captivate (cptvt3500_1) is also overblown, but for $10 a pop you get a battery with 2100mAH worth of juice. It is 40% improvement over stock

}
See “more detail” below to know how 10oHM and 50oHM loads effect the test.
See LiIonTester.zip for all test data
TEST SETUP:
The batteries were tested with special circuit outside the phone. This is a true battery capacity test. Results are not skewed by the installed custom ROM, overclocking, varies apps and interfaces that can be on, usage pattern or out of whack battery stats of the phone.
Li-Ion batteries operate between 2900mV and 4200mV. 4200mV is fully charged and 2900mV is fully drained. Battery tester works within the normal operating range.
The setup consists of the discharge circuit, microcontroller board with the potentiometers(voltage meters) and LCD. Discharge circuit is just a power resister wired across the battery and power FET( transistor) turns the circuit on and off. Transistor is controlled by microcontroller that monitors the voltage drop, calculates the current and controls the test. Test stops when voltage drops to 2900mV.
See my rig's schematic and pics in the attachment below
MORE DETAIL:
samsung1500_1 after 6 months of use still put out 1426mAH in my test environment. china1800_1 puts out only 1275mAH after 1 month of use. Li-Ion battery real world capacity depends slightly on the rate of discharge. The faster the discharge, the lower the effective capacity. In my tester circuit the discharge rate is 370mA per hour. It takes roughly 4 hours to drain the batteries. This is within the spec, but on the higher side. One of my co-workers suggested that cheap chinese batteries might actually have the same chemical capacity, but due to sub-par manufacturing process, internal resistance is more negatively effected by the higher discharge rate then higher quality Samsung OEMs. To check out this theory, swapped 10oHM resistor for 50oHM. This change decreased the current to ~74mA. It improved achievable capacity, but only marginally. Improvement was within my earlier expectations.
Cycling of the new battery doesn't change capacity, but it does effect phone’s circuitry that estimates the charge. To the end user, it appears that battery improves over time. It really doesn't. Estimators within the device get smarter as they learn the properties of the battery installed:
http://batteryuniversity.com/learn/article/is_lithium_ion_the_ideal_battery
china1500_1 put out 1323mAH, but it was only advertised at 1500mAH and sold for pennies, so I am not complaining. The one weird problem I ran in with china1500_1 was its voltage unexpected collapse. During drain cycle voltage went down slowly to 2800mV and then precipitously dropped to zero and stayed there. Other two batteries, drained normally down to 2700mV and after the load was removed voltage went right back above 3000mV. It turns out china1500_1 has battery overcharge/undercharge protection circuit that shuts itself off at 2800mV. This observation was the part of the reason for minimum voltage change to 2900mV.

UPDATE: 01/15/2010
* Tested another 1500mAH battery. My co-worker bought and gave it to me to run the test.
* Upped test minimum voltage by 200mV to 2900mV to be on the safe side. Remaining battery capacity below 2900mV is only 2mAH. This residual capacity is consistent among different batteries so it should not skew the results
* Added slow discharge rate test to show capacity variation range

2700mV is fully drained battery. At that point your phone will not turn on without plugging the charger. There plenty of reference material on the web that point to this number. Here is wiki:
http://en.wikipedia.org/wiki/Lithium-ion_battery
To put together my tester I used following design, with some of my own modifications. It also references 2700mV
http://www.instructables.com/id/Arduino-True-Battery-Capacity-Tester-Li-IonNiMH/
Now, if you look at the data in .xls file, notice that the battery outputs only 3mah as the voltage drops from 3000mV to 2700mV. This is the same in china1800 and samsung1500. So, it might be worth while to modify my rig to stop the test at 3000mV.
This is such good information.
Thank you VERY much for taking your time to write up a detailed result from testing each battery.
Looking forward to your verdict on the 1900mAH.
Thanked the original threaded. Much deserved.
I read in one of the threads that the first 2 or 3 discharges were really bad but after there the battery began performing better.
did your run this test on a brand new one or one that has been cycled a few times?

Cycling of the new Li-ion battery has no effect on the battery capacity, therefore it has no effect on my tester. When new battery is discharged/re-charged couple of times circuitry within the phone learns about the true battery capacity and device battery life improves. Here more info on that
http://batteryuniversity.com/index.php/learn/article/charging_lithium_ion_batteries
I used 1800mah Chinese battery for one month, at which point I really wanted to validate the capacity claims and so I did the research.
Awesome work. can you test some of the claimed 3000mah and 3500mah extended batteries?
Also not sure if you have heard about the SGS Armani that supposedly comes with a 1650mah battery stock.
http://forum.xda-developers.com/showthread.php?t=886743
Great info, thanks for doing this! Can't wait to see the 1900 review.
Great info, just what I was looking for. I look forward to your 1900mah battery review. Also if you get the chance, could you test the acclaimed 1850 battery?
obostore.com/1850mah-andida-spare-battery-for-samsung-galaxy-s-p-315.html
lokhor: I believe this Armani battery is the one to watch. The only rating's claim that seem to connect to reality is Samsung's OEM.
1900mah battery is in the mail. Should be testing it in a week or two
Heh, my 1900 mAh is in the mail too. We'll see, though I do not keep any hope, really.

So this is not actually based off of specs from Samsung saying that our Captivate phone need X amount for the system to run. Keep in mind that I'm wanting to know what is the minimum amount of voltage for the phone to keep operating rather then for a phone to turn. People want to know how long a battery is going to last from 100% until the phone's internal system forces it to shut down. Its good you are doing these test but we can't really say for certainty that either battery is good or not. Let keep in mind for every one doing tests like this you really need to take and test more then just one battery for each brand. Each manufacture is going to produce bad batteries in every batch... which is very easy to do if you look over the process of producing a Lithium-Ion battery. One mistake and the battery can easily fall below the intended specifications. It just depend if the manufacture is going to catch those bad batteries or not. OEM batteries likely have a lower chance of a bad or low performing battery to be release because Samsung likely requires more testing of each battery or batch of batteries. I can't say that for 100% certainty.
I've by no mean want to test batteries to the degree I recommend above as I really don't have the time or resources to do it. On the other had I've been using the 1800mAh battery for over 2 weeks now and it works at least 10hours longer (40-50 hours total) then my OEM battery (30-40 hours). So does that mean my OEM battery is bad or is it that the 1800mAh battery is just better as the sellers claim? We won't really know because we haven't done any extensive testing. Let just not jump the gun too quickly because one battery was tested.
I don't mean to be a jerk or anything... just my $0.02. And just for the record, I am no way promoting to buy a aftermarket/extended battery... Honestly you really should stick with a OEM battery as it has the lowest possibility of causing damage to your phone.

I would really like to keep this thread free from comments such as "My phone lasted this much longer" It is hearsay. It doesn't really help much and discussed to death in other threads.
On the other hand, I was waiting for somebody to bring up sample size. It is a valid point. I only tested one battery. So, if you believe your battery lasts longer and you want to help out, send it to me and I will test it! If you include self-addressed and stamped envelop, I will send the battery back to you after test is done. PM me for more details

No offense but chinese quality control is a joke. It's like a lottery.
No doubt in my mind the value (performance/cost) is still better than OEM. Please don't expect the miracle that the capacity is as advertised. Just use it as a emergency/backup battery and be happy.
I think there might be a quality control issue here because I am having excellent results with the chinese battery.
I can't wait for the 1900mah test. I found that battery after I placed the order for the 1800.
Thats almost 27% claimed over stock. That would be a significant increase if its true.

Best part is - my phone still fits inside the stock leather protection case by Samsung !!!
Now the phone feels more high quality.i feel like im holding a sturdy HTC phone.
Im very happy with the quality Mugen provides always.

So here are some pics.(will post pics in day light soon).
And whats the percentual gain over stock 1650 mah ? Dont think this one is full 3200 more like 2400mah
Also, some pictures with it installed on the phone would be appreciated

Cant speak anything about the performance as of now.lets wait for a day or two.
I'll upload more pics tomorrow.first thing up tomorrow morning.

Wow. No offense but I'm slightly worried it might burn the phone. Rather go with the official Samsung battery release of 2000 mAh.

i have been using Mugen Power batteries past 2 years now
i have had no issues with my previous phones.
Yet,i'll take care of what you have said.
Regards,
Karan.
Yeah, Mugen makes quality batteries... It is not some 10$ ****
Urghh, all that extra thickness on the phone and expense for an extra half days usage (according to the real world usage stated on the youtube video).
I've got it and it's more than doubled my phone's life... with Data and auto sync always on.
It's more like a 4200 mah battery.
I get about 20 hours with Data, auto sync & Bluetooth always on
Wifi is on for about 10 - 12 hours a day also.
I got 65 Hours on a single charge with data off the whole time.
I had wifi on for about a third of the time.

screen on time ? Thats important... Im getting 5 hours with genuine 2000mah from samsung. Im considering buying this battery, but from my experience third party batteries are usually crap(momax for example), and this one is 70 euro. I will buy it only if it really is full 3200 mah. So I am waiting for some kind of test.
Mugen are the only third party battery I trust, Had one of their batteries in my old HTC Hero and it was fantastic, lasted me 4+days on a single charge (I could stretch it to 6 days with data/wifi off and just texts and calls).
I just have to 'lol' at people saying "ooooh its so expensive compared to other ones!!" and "It will blow up your phone!!!111!!!1!"
Its expensive because its not cheap nasty [email protected] like 99% of all the other aftermarket batteries. It may not be the full 3200mAh but based on my experience with the HTC Hero version I wouldn't be surprised if it was still 3000+
It wont blow up the phone, its Mugen.
A google for 'Mugen Battery Review' is all people need to do to find out how highly Mugen is rated

Momaxes is certainly not crap, Tids2k already measured the capacity of the extended Expower to be right on the money, 2680mah out of the rated 2700mah. At the very least it's better then the spider-foot/adinda/oem extended batteries (Rating 3200mah, real cap 2400mah).
Cover is not confidence inspiring though, I have to admit. It HAS survived a couple of drops before though.
On the other hand, nobody seems to have tested the Mugen for total cap yet. Holding on my purchase until someone does.
Watching that video of the increased phone thickness, even this phone is thinner
I think it's better to have 2 or three genuine samsung batteries than having 1 gigantic battery that sacrifice our phone's slimness..
Can you advise what is the total charging time from 10% to fully charged with this extended battery?
The original one takes about 3 hours to fully charge from 10%, using power socket charger (not USB) and with data packet/wifi/GPS all turned off.
What point are the people posting in every single extended battery thread about slimness or ugliness trying to prove? You are providing no information in regards to extended batteries which the post is about. Thanks to the public demanding slim phones we all have poor battery life. Shut up please.
If the phone was twice as thick you could have reasonable battery life and it would still be easy to handle and pocket, why you need a phone thats >10mm thick is beyond me.
exactly! Prove us what you have. Do not just talk like insane.

Checking it... show me the actual screen usage statistic (screen on time)
see ? Thats my 2000mah battery, dont see much difference, show me screen on time. (those big drops are order and chaos gameplay, pretty good for 2000mah eh ? + The total screen on time after three days was 5 hours.)
This is what I mean:
Im sorry for my scepticism... I just saw things many people overlook, the momax 3500mah battery is actually 2400mah and double the size, the other 1900mah batteries are really 1300-1400mah. Only the samy batteries match the rated capacity, my 1650 mah stock battery is 1614mah and my 2000mah battery is 2035mah according to my discharge tests. Thats why I dont trust 3rd party batteries. I just dont see small company squeezing same or more capacity into same sized battery because I am pretty sure they cant invest as much money into battery manufacturing process as samsung and thats why sammy batteries actually match the real capacities.

I'll run another test and let you know... this screenshot is about 2 - 3 months old...
How can i check the actual capacity of my battery?
This battery does last at least 2 - 3 times longer than the stock Samsung Battery.
Just checking the post box and lo and behold my Cameron sino 2200 MAh battery had finally arrived from England.
It looks like the real deal but only testing will tell.
I purchased in from this Ebay shop.
They delivered it via Royal Postal Service and considering it is the Christmas season it took 14 days instead of the usual 8. Not bad.
The battery and shipping cost me around $22.00 US.
It's charging right now on my universal charger so I still have the use of my phone but I did take some initial photos of the difference in the case size, battery, etc, to post.
My initial response was...whoa! Big! It's exactly twice the depth of the OEM battery.
The back case of of a smoother plastic and not as "grippy" as the original. It's well made and fits perfectly.
The battery itself it a surprisingly tight fit. At first I thought I had gotten the wrong size but it finally popped into place and sits snug in the case.
In hand it feels different of course. Only with some use will I be able to really tell if it's a benefit or a detriment to have a case that size in hand. I have big hands so it might actually end up nice. Some swyping and other activities will tell and I will report of this when I do.
I did a test of the camera with the inset camera and flash holes and there are no blackout spots in the pictures, nor do they suffer in quality as a result of the case.
I had a theory that this case would be provide more bass by acting as a passive subwoofer cavity and indeed it does although I tested it with the standard battery installed. With less cavity space with the CSI battery installed it should fall somewhere in the middle.
One of the things I noticed is increased low end response was created with a sacrifice in overall volume which makes sense. Will report further once battery is charged and there is a little less cavity space inside the casing.
Below are some pics of the batteries, phone profile, etc.
I will follow up with usage test results once it's charged and in the phone.
Battery charged fully after a couple of hours as it was already pre-charged for a bit. On the phone and Battery Monitor base battery profile created. Will find out the true mAh once I deplete and recharge it once.
I hope it will be a day or two before I report in on this.
EDIT: Update
As I would have bloody well hoped, this battery does extend the life of the Wildfire S by quite a bit. Still trying hard to wear it down here by playing some games, coming up with a new tutorial, some recording of me playing guitar with 4 Track Pro, etc.
No solid stats yet but I will have after a drain and recharge or two.
Battery stays at a cool 25-26 degrees centigrade in operation and was cool to the touch while fast charging on the universal wall charger initially. I''ll provide charge while in use stats in short while.
EDIT:
11:10 pm and this thing is still charging. It's a lot of juice to squeeze in I guess. Waiting patiently and then I will post the charging profile screen shot from Battery Monitor.
EDIT:
12:00 pm and the battery is now showing full. Removed battery stats file and doing a complete drain. During charging while using the battery next jumped above 26.5 degrees centigrade. 10 degrees cooler than the stock battery.
EDIT:
2:00 pm and the battery is at 85 percent with moderate usage. Didn't get to sleep until 5:00 am and was up at 11:00 am checking mail etc.
I have to say that compared with the other WFS with the standard battery I REALLY like the feel of this double sized one in the hand. I find it easier for Swyping and general use. It just feels substantial and cups in the palm of your hand in a way that the shallow case doesn't.
EDIT:
The battery is still going strong. Used it heavily last night doing backups and playing Words With Friends online, tapatalk, gmail etc. for a long while. Had a mega text session with a cute girl.
Just after 3:30 PM on day two. Battery finally powered down after a heavy use phase for the last 10% for a total runtime on the first full charge of 40 hours.
Way cooler than the stock battery. Never got warm to the touch. Clocked in at 26.5 C at it's highest temp.
Apparently they even out and get even more capacity after a charge or two so if I get this up to 48 hours with moderate to heavy usage I'm thinking Phat is the new Thin! ;-)
FINAL UPDATE:
Battery charged over 7 hours while under a heavy load playing games.
All in all I've gotten used to the size, love the amount of power and longevity I get, it stays cool, and the price was great.
Next up... Ecell gold 2430 mAh standard sized lithium polymer review.
Coming soon.

Hehe.
Yah it's not the smallest but I'm liking how it feels in the hand even though it's no longer a Zoolander cell.
So far I've been running it hard since 5 pm or so yesterday. NANDROID backups, restores, lots of web time, some games, FB, doing a bunch of root stuff to fix GPS and figure out WiFi issues. Sitting here with another couple of estimated hours left on it. Trying to run it dry for a calibration or two and it's taking a while to say the least.
It's like the weekend pill Cialis...You could call this thing the weekend battery.
I'm going to order...cough cough...I JUST ordered the 2430 mAh Lithium Polymer from Ebay and I'm going to try it as well to see if I can get this kind of run time out of a standard sized battery.
Me <3 testing...
Hey bud. What was your usual 100 to 0% time on the stock battery?
Mine was usually just over 11hours.
With the CS battery 1day14hours (gets better after more cycles)
(note that leaving a phone on standby over night is going to drain less than a working day.)
I'm interested in knowing how you get on with that Gold 2430.
I dont expect it to beat the 2200mah CS but if it gives 25-50% more time over the stock battery with a standard formfactor then I'd be impressed.

Mine was in around 16 to 20 hours based on my usage.
I'll give you the stats on this one after it runs dry. Down 10% over the last 13 hours so far.

That's the test I'm more curious about. Anyway I thank you a lot for the review on the FAT battery. It's bigger so it should be better. As I already wrote on another thread I've had nice experiences with Cameron Sino batteries.
I'm curious about the Li-Polymer because the density and weight of the material are totally different. If that one approves I will buy one for sure.
Simply put I don't want to change the aesthetics of the phone to a Big Mac.

ROFL. Nice.
As I said I like the Big Mac. But I do prefer a Quarter Pounder to be honest.
I figure I will keep two battery stats files and swap from the low profile to the big mac depending on usage needs.
Going to the bar or something, it would be nice to have the smaller phone in my pocket so it doesn't look like I'm over-compensating.
I have read reviews on here where the 2430 clocks in around 1700. In my opinion for $20 that's a worthwhile upgrade to get nearly a third more batter life. Time and testing will tell though.
It shipped today. Hope to get it before Xmas.

Good luck with the shipping time and with the batteries too.
If the Li-Polymer Gold battery only has about 1700mAH then it is pretty false advertising. My feedback would be pretty negative on eBay.
Sellers shouldn't be so greedy and announce values that are way above reality.
Anyway if 15.50€ gets me about 30-35% battery increase then I will probably buy one.
An original battery costs the double...
I will wait for your review before I decide because I really don't like ordering so near Christmas...
Thanks for your help mate.
No Problem. Up to 37 hours with moderate to heavy usage now.
Final update. 40 hours on first charge.

This means that on the 3rd or 4th complete charge cycles you will probably get a few more hours. Just follow the battery maker's instructions and I guess that 45 hours of moderate usage will be possible. That's quite an achievement!
Even if it's a Big Mac, for work purposes that wouldn't be a problem.

Cameron Sino still takes their business very seriously. That's great!
OP, can you come back after a few weeks using this battery, and do a 2nd review to see how it's lasting?
I only ask because I tried a similar 3500mah extended battery, which was amazing for the first few days, but after a week or two it started losing it's charge realy quickly.
40 hours use from a single charge seems awesome, but I don't wanna go spending on another battery until it's withstood the test of time
No problem. I'll put it in my Calendar.
Awesome, can't wait for the results
Nice testing,we shall se if we have new battery champ for our nice wfs
hey guys,
So I got both of this big boys and decided to do a side by side comparison. I can tell you both are very good batteries ..both do their job and for the price gap between them the difference is not substantial .
If you are still undecided which battery to pick, this review might help u
Enjoy!

Great review TY.
Bought my innocell 3800 about 4 weeks ago and love it.
Price is a bit steep, but nfc compatible and super long lasting.
Average use I get 36-40 hours (nonstop LTE). And heavy use about 25-30 hours (nonstop LTE)
Again thanks for the review

Glad it helped you!. your times are similar as mine. I think its a good investment ..but I cant use extended batteries all the time. I like to retain the thin profile..Man i even hate cases but Im too stupid to not have one because I drop phones like crazy lol
I'v tried Seidio innocell and its pretty good
here is what i got from it

would love to try out the Mugen battery
Thank you so much for the video review! I always hated extended batteries because of how it made the phone look, but I think the mugen battery cover doesn't look bad at all. I think it's because how it looks at the end/bottom of the phone (doesn't protrude out as much).
I felt the same way at the beginning, had to go back to my original nexus with that amazing curve every so often.
But after a while the extended battery just grew on me. Especially with just the skin tight case.
I did notice tho that now I seem to be getting a bit less battery life especially after a bit heavier usage.
Ill try battery status wipe in cwm and do another 2 rounds of full charge to discharge.
How do you go about your charging patterns?
Do you -
1 - full charge to discharge every time?
2 - full charge to to half and back to full?
3 - full charge to x% back to full?
And has your battery life been dropping slowly? I.e. getting less hours per charge.
As it stands now it seems to have lost roughly 3-4 hours after the same usage as when I first got the battery.

I try to go from full charge to like 10 or 5 percent however work and school dont let me do that everyday. so little charges here and there happen all the time . But at night if im low i let it charge
nope I didnt get that issue at all..But what i found with every single extended is that the first full charge is INSANE ..its so good that creates an standard..I dont know why lol but after that its been steady.
What rom are you on? And do you have any battery mods?
I'm on arhd 4.0.1 with the circles mod.
You think that could have anything to do with it?
I'll post back in a couple days after the battery wipe and full charge. Maybe my battery mod is throwing it off.
Thanks again for the info

nice! I hate how some little things can screw things up
Wow, this review didn't help at all. When buying a battery the most important factor is how long it lasts. The mAH values reported by the manufacturers are meaningless so battery reviews are there to test how long they really last. This video review was nothing else than just a comparison between the back covers provided with the batteries.
Next time charge both of the batteries and then do a heavy usage test with them. A regular heavy usage test would cosist of running an internet stream video on constant brightness. That way pretty much everything is being used: screen, radio and processor. Then have both phones running the same video in a loop until they run out of battery and see how long they last.
So how about you buy both those batteries and buy 2 galaxy nexuses and do a review yourself? Then provide us your input on what you have found.
I do agree that the person left out an important part but he did do a battery review. Any information is appreciated and physical features can make or break a persons decision on a product even if it isn't important to you. I for one will thank the reviewer on his input between those batteries and leave negative comments out the window.

I think the charging pattern is not really relevant when it comes to li-ion batteries...what is important is to make the phone understand that there is new capacity used. These hi-end batteries last for 400-500 recharges so I think that if you get less battery life, you should just re-calibrate it.
Mugen btw has a user-guide with calibration process described there http://www.mugen-power-batteries.com/user-guide It's a no-brainer for a generic user, but it does it's job. Just I don't think it's good for your battery if you do it often...
Hey guys,
I still had over 4h SOT all the time so I didn't think about testing the battery capacity from my Mi mix 2 but now I did.
The phone was automaticly shut off at 0% battery life and charged to 100% + 30min while it was shut down.
Look at this garbage, you should check your device to cause the Battery is rated at a max of 3400mAh and 3300 min.
PS: My device is not even three month old.

Maybe you just got a duff battery, send it back for RMA/warranty. Mine's working fine.
Are you sure this test you have done is 100% accurate?
I have my Mi Mix 2 since end of September, and battery life is still as good as first days
I don't know how you were testing, but I suspect it's not quite the same as how the OEMs rate their batteries. For example the discharge rate, ending voltage, and depth of discharge will all affect the reported capacity.
Unless I'm really using the phone a lot, I easily get two days' usage between charges. So it doesn't matter to me if the battery's "true" capacity is 3400 mAh, 2700 mAh, or 20 mAh ... bottom line is I'm very happy with its performance.

I am pretty sure it's not quite the same. He would probably have around the same result when testing any other smartphone.

No it's not 100% accurate, cause there must be a few % reserved so the battery won't die completely from deep discharge.
But the result how much goes into the battery is correct. I also attached the device to my oscilloscope.
And no I don't get such bad results on other phones. (Tested with an iphone, nexus 4, LG Flex 2 etc.) Also some cheap chinese power banks have better ratings.
If someone else could test it that would be nice, cause I haven't found any spare batterys so far...

Try a regular 5V 2A charger in stead of the QC3.0 charger that's in the box, i'm pretty sure your result will be different.
Seems like you are coming to a conclusion pretty quickly, you are bringing it like everyone should expect a 2700mAh battery in stead of a 3400mAh. One guy's battery test does not exactly represent all units out there, even if your test is fairly accurate.

No the results won't be different. I can measure from 0.1 to 50V and as I said I did a second test in which I had my oscilloscope connected the results were the same.
And you're in the wrong again, everyone should expect at least a 3300 mAh battery minus the capacity which is reserved for deep charging like how it is stated on the battery.

Yes i'm wrong, you are right. Thanks for all the scientfic evidence and extensive testing. I think everyone should BEWARE now, they will all get a battery with only 2700mAh capacity.

Yeah you're. Check the ****ing battery ratings instead of flaming me and talking nonsense. Where did I say Everyone has a battery with only 2700mAh capacity?...

Calm down
Hmm
There is a possibility we haven't talked about - the BMS only charges the battery to 2.7Ah and leaves the rest untouched. Why? Because as the battery ages, the BMS may adjust to charge to greater capacities to compensate. This is a technique I have seen and implemented in my own projects with LiPo and LiNMC cells with small drains.
If the pictures and OS are accurate, the battery is rated for 3.4Ah.
If the measurements are correct, which seems plausible, we may only be using 2.7Ah.
Tell us more about your battery shutting off too early. Custom ROM? Bluetooth?
I've only owned the phone for a few days and it's been fantastic - I get MUCH better battery life than I expected. The system reports 3.4Ah, but I will plug my phone into a coulomb counter when I get a chance.

Same as that. A steady 6.5 to 7 hours SOT everyday.

Same here. If it's only 2700 (which I doubt) then it's a damn efficient phone.
Ok look what a User named MPC561 found
https://de.aliexpress.com/item/3400...2de2-4c16-8d0e-ac23fbd88f3a&priceBeautifyAB=5
So ali is selling Mi Mix 2 batterys. Obviously they are not "original" but most likely they are just rebrands coming out from the same factory.
Ali is rating the battery from 2801mAh to 3500mAH.
I suggest other users to also test their batterys so we can figure this out. If Xiaomi has lied with teir battery ratings it was the last phone I bought from them. Cause if the rating from Ali is true it's ****ing battery lottery.

There's nothing to figure out. If this thread didn't exist you wouldn't even bother looking into it.
If battery was so important then everyone would be buying power bricks

Yeah sure, just because you have a good battery doesn't mean everyone can be happy.

Yeah sure, just because you have a bad battery means Xiaomi lied about it.
Here is my results from 10% to 100% via QC3.0
I dissapointed
