Software to test 3500 mah battery capacity?

I have a 3500 mah battery I bought from the dark side of the moon. It "looks" real and it will operate my phone, but is it REALLY 3500 mah?
Is there some sort of software that I can download that will tell me the battery's capacity?

Thinking about this.
The 1500 mah stock battery charges at a max rate of 650 ma's (even with a 1 amp charger) and takes roughly 2.3 hours to fully charge.
I suppose I could charge it from 50 to 60%, determine how long that takes and multiply by 10 to get the approximate charging time. I say approximate because EVO batteries take less and less juice as they approach 100% charge.
So anyway, once I have the approximate charging time I can multiple that by 650 and get the approximate mah of the battery:
So, if it the total charging time is 4.5 hours I would just multiple 4.5 x 650 and get 2950 mah as the capacity.
I'll try this and see if it works.

try batteryboss.org, i think he had ordered one from hong kong to test, the seidio only did 2810 mah when he tested it, I got one of the 3500's from the states but it is the same as the hong kong version lasts the same as seidio ... way better than the stock 1500, but your method should work as a rough estimate i think.

Did a quick first pass. It took about 13 minutes to charge 10%.
That's 13 x 10 = 130 / 60 = 2.16 x 650 ma = 1408
So, on first blush it would appear that my 3500 mah chinese battery is actually a 1500 mah battery stuck in a 3500 mah battery case.
Sucks, but on the other hand, I got 2 1500 mah batteries for $20 which isn't a bad deal. That being said, do I want to have a big heavy phone for a battery that is no better than my stock?
On the other hand, not being a stock EVO battery, this battery may actually be charging at a full amp. That being the base, I am closer to 2500 + which wouldn't be bad at all. Have to download a amperage testing program and see how many amps it is drawing while charging.
** They never tested the chinese battery at batteryboss.org

OK, installed Current Widget from the Market. It will log my average amperage during the test and we'll find out what's what. I think the answer will be that this chinese battery with 3500 mah written on it is really just a 1500 mah battery.

Well, based upon my Current Meter, the charging amperage is all over the place, mostly between 450 and 550 ma. If that is true, then my calculations change:
13 x 10 = 1300 / 60 = 2.1666 x 500 (avg) = 1083 mah.
Just keeps getting worse.

Omg? I hope that battery isn't from GorillaGadgets.com
Edited: I bought one last night, gonna arrive 10 days.

Well, these tests I am running arent exactly accurate. However there is no way a true 3500 mah battery would charge 10% in 13 minutes. Not possible.

Ok, I have two of these 3500 mah batteries. I decided to sacrifice one to science since it was so cheap. I tore it apart and here is what I saw:
Instead of one battery, it looks like two batteries kind of jerry-rigged together. There seems to be connections on both batteries top and bottom. I have no idea if a true 3500 mah battery is supposed to be one solid cell, but these are not.
The batteries have a serial code on them: 044060A JK30
I traced these to a company in China by the name of: Dongguan Delon Power Co., Ltd. They do, in fact, make these batteries; however, there is NO MENTION anywhere on their webpage whatsoever of what the mah is for this particular battery.
In order for this to be a 3500 mah battery, these would have to be two 1750's. I seriously doubt they are. I'm calling BS.
Here are some pics:

i was about to say the same thing. your best bet is to charge completely, then run it to zero while logging current. then you can import the log to a spreadsheet, and calculate the capacity from there. this wont be perfect, but it will eliminate a lot of variables, and give a fair comparison with stock battery.

Well, at this point the most interesting thing is that this is NOT one battery but two soldered together.
The odd thing is that on every site I checked that sells these, it does NOT list the mah, only the voltage. How the hell are people supposed to buy them if they dont know the mah?

first sorry about bumping such an old post but again i think someone may visit and not get good info so i will add some words,,
these lion batteries charge extremely fast initially only after reaching 90 percent their charging becomes hell slow,,
so to test a battery first take ur oem batter drain it until ur phne shuts offs,,
now put it on charge and after 10 minutes turn it on dont use it ,, just leaveit,, let it fully charge,, fully charge means when ur cell prompts charging completed. or done or 100 % done etc,, note all this time,,,from the time u put the attery till it became full,,
now look at ur charger for output current and multiply that with the amount of time in hours ,, e.g if it took 2.3 ( 2 hours approx 20 minutes) hours and ur charger current otput was 1 amp,, then the ans is 1 x 2.3 =2.3 AH,,, or 2300 mili amps,, now the charging process is not eficient ,, its 30 % loss so get 30 % of 2.3 and subtract it from 2300 mah,, that is ur rough capacity,,,
do same experiment for the high capacity 3500 mah battery as well,,
als weight is another factor which can alone tell u at least if the high capacity battery is having more capacity then current oem or not..
repeat that process...2 or 3 times get the mean u got some good figures,,,,
remember that batteries capacity is not accuratly advertised ,, it may be off by at least 5-10 % for good quality cells ,, poor cellls may be 50 % off from rated capacity,,in that case u can weight the batteries to get an idea,,,
so what r ur results ?
r those batteries still alive

External Battery Pack - your pick?

Long story, but need to urgently place an order for an external battery pack. I personally need something that is compact and gives me at least three full charges on a single charge.
The hunt has led me too this one, has loads of positive reviews as well - New Trent ifuel IMP500 5000mAh External Battery pack.
Apologies if mistaken, but I don't think there's a thread dedicated to external battery packs... thought this one one could help a lot of people discuss their experience and also seek help on deciding the right one for them.
Coming back to my case, anyone here used the above model? Any other recommendations?
TIA.. Cheers!

I just bought this one when it was on sale for $49 over Memorial Day.

So far with stock S2 optus brand KE2 at 26+ hrs uptime after letting battery run down to 24% once and ~50% twice so far. 100% wifi enabled all the time with 5-6+hrs of Angry Birds hehe

@BarryH_GEG
The Zagg one for $49 sounds like one sweet deal... too bad I'm a few days late !!
@connectandroid
Checking out the energizer... btw, awesome battery performance u got there mate!

Have read several issues with these external power packs not charging the GS2... can anybody confirm successfully using this/any Trent product?

XP8000 ain't even half empty yet.. i probably estimate get a total around 40-50hrs with S2 battery + XP8000 on KE2 firmware.. alot longer on KE7 i suspect. Folks jumping from 8hrs to 24hrs with KE2 -> KE7. So 120-150hrs with S2 + XP8000 on KE7 ?? I hope so LOL
Yeah some external batteries aren't charging. The XP8000 to initiate the charging your press the check battery/on button (you can see in photo above to right of blue led status indicator).

I use a ZaggSparq and an XP18000. The XP18000 usually charges my laptop, but it works hella well in charging the SGSII.

So with my XP18000, I should be able to get close to 100 hours!

Yup probably more with 2.3.4/KE7, say 120-150hrs

The Proporta Turbocharger 3400 and 5000 are the best price/performance packs, and very small in size too. The 3400 will charge the device 1.5-2x, and the 5000 3-4x.

I have the 3400 and it has saved my life many times. I will be buying the 5000 soon too. t_id=5287&t_mode=des

Fry's sells this 5000 mAh pack for $30. Of course for that price, you have to supply your own charge cable.

Interesting, I've got a no name brand 5000 mAh, and it works great!

Swiss Charger GPower 1500 mAh Rechargeable Battery for Samsung Galaxy S II

Anyone heard of this product called "Swiss Charger GPower 1500 mAh Rechargeable Battery" for Samsung Galaxy S II? Any reviews about it?

it looks very nice but cant find any reviews on it, would be keen to see the quality of it

I have been using this product. It is good...it charges your battery to almost 60% from complete 0..very useful while travelling...
Plus with its box it accompanies a PC-Phone cable and 1 scratch guard.

Swiss Charger GPower
Hi
I have been using the Swiss Charger GPower for more than 3 months now,
Pros
- Does the job of adding extra battery backup
- adds 40% more battery backup
- give the phone a bit of protection
Cons
- the sleekness of S2 is lost
- makes the phone heavy a bit but extra battery time is worth it
Issues I am facing
- I have a S2, GT9100G, 2.3.6 stock none rooted device, i used to find that the USB connectivity with my widows 7 64 bit was not stable,
- just after 5 min the device would not work and the driver will show "device not responding"
- removing the USB cable, and reconnecting brings back the connection
- to hold the connection, I had to keep my finger moving on the Phone screen looked as if when phone goes to sleep, the USB conenction was not waking up
I contacted the Samsung service - and as a solution the reflashed my handset, things worked fine and my phone was connecting normally with no failure
but
when i put it back in the Swiss charger and try to connect, i have the same issue - so the original issue was not with the device but with the charger
has anyone faced a similar problem? what is a possible solution?
Will appreciate a reply as changing between covers might take its toll on the phone
Cheers

hie i bought this swiss charger yesterday in india..
it started well showed 2 dots of charge level...
i utilised it to charge my sgs2..
bt aft dat it didnt showed anything..
its not showing battery level even aft keepin on charge whole night with my cell..
pls suggest me how to charge o replace this product...

Dear Dholyabhai,
When you press the power button of GPower, it shows the blue indicator that it is charging, the amount of charge at hand is indicated by the number of blue indicators. but after some time the indicator does not show up (I guess this is to save power wastage). you can still see the phone being charged in the Phone charge indicator on the notification bar.
when put the phone with Gpower to charge, it looks both get charged and since the battery now is 1500+1650 the time taken goes up a bit (depends on the charger trickle rate)
Cheers

can someone post pics of this

Today bought this device in Spain (25 euro), was looking for it before in Ukraine, but only available by preorder.
Nice looking while SG2 inside, soft touch quite durable as for me.
Everything else you may find on above youtube video. Definitely Gpower "must have" device for long range traveler as me.

that swiss charger does look ok , have you ever thought about one of these
http://www.amazon.co.uk/TeckNet®-Du...1?s=electronics&ie=UTF8&qid=1335310567&sr=1-1
or even a desktop charger and spae battery??
that usb battery pack i linked should be good to charge your sgs2 over 3x from empty on stock battery

That one also good which i use now (see screenshots). The big advantage here that you can insert any capacity NiMh accumulators and also ordinary unrechargable batteries. Moreover if accumulators inserted they are charging slowly via sunlight panel + you got long lasting flashligt packed with 5 diods. Tested one time on 2500 mah NiMh accum. constant lighting time more than 24 hours.
So now I got extended battery 2000 mah + swiss charger 1500 mah + extra accum set 2500 mah = 6000 mah total power.
I bought this device 3 years ago in my city and still it selling here. Price is around 35$. It comes with commonly used adapters for Nokia, Ericsson, etc phones + microUSB+miniUSB.

[Battery review] Hyperion / Anker / Mugen

initial look
-the package came in yesterday, very well wrap, as well as most MUGEN battery. Charge the battery for 14 hour as per instruction (atleast 12)
-battery definitely heavier but not uncomfortable heavy its actually quiet the contrary, feels very firm on the hand.
-battery came in at 60%
Benching
-both core lock to 1.8
-screen on full 100% brightness
-ambient temp 72-77
-navigation on, tune in radio tune to 192kbp channel
-wireless on (discover mode)
-bluetooth on (discover mode)
will compare over the weekend as this process could take an entire day.
initial benching Look at page 2
Benching after charges
-Judgement: Guys i realize i dint have one of the app running hence thats the reason why the battery time was so high, but after a week this battery only last 2 hrs and 15 minute under hard benching...is it worth it? i dont think so.
-buy or no buy? better find something else

will do one today, still have my S2 so i will post it up when i get home. as far as link goes, you can get them on ebay or amazon.

Yea, the Hyperion works very very well & so does this setup:
http://www.wirelessemporium.com/p-1...ase-for-samsung-galaxy-s3-black-2400-mah-.asp
I have one of each, the helios is different in that it is thinner but longer & adds to instead of replacing the stock battery.
I like the helios because I can use the stock light battery with my Rock Quicksand case until it dies & then just snap the helios over it. The stock battery recharges from the helios.

My Hyperion battery was horrible, lasts me half a day, i returned it to amazon.... the OEM battery and the anker i got is similar... both have 30+% left at the end of the day

My lte siii gets 4 hour screen time and doesn't die. That OEM battery.

OEM result are in....will post when HYPERION is completed

I picked up a cheap OEM-knockoff for quick-switches and emergencies. I love these super extended batteries (I turned my old Pre into a hockey puck of death with it's extended battery) but without supporting NFC it's a no go for me. I'm really hoping these third party manufacturers realize how much they are missing out on by not including an NFC antenna (I would gladly pay 10-20% more for NFC if they offered a real double-capactiy extended battery as well).

Test
-stability test running at clock 1.8ghz both cores are on, performance governor set
-Tune in radio were streaming 192kb station
-brightness is full on, 100%
-Wifi were on but not connected (discover mode)
-Blue tooth were on but not connected
-ambient temp is 74 degrees
OEM
disregard unuse in the begining. it was very slight, if you want you can call it 1 hour and 47 min
Hyperion
*FIRST ACTUAL FULL charge
roughly 25% more capacity
hyperion capacity roughly 2625Mah
more test will be conducted once i fully charge the Hyperion battery, factory recommended 3-4 charge before full performance on the battery.

lol yea good point...plus it really add heat to the phone...your basically charging that thing as you go, two battery feeding off of each other, the combine heat may cause problem for the phone or the user. i had one of those before and its not worth it IMHO

OP, I know this is off topic thus the request. Is there one out there, if not, can you put up a thread on TM speed test using your S3?

I did a litlle review of the Hyperion battery. I know you said no tweaks but here's the time I got with heavy use but I tweaked the hell out of it.

Battery Problem (Charging and Draining)

I got my Note 10.1 2014 Edition yesterday. I noticed out of the box that it was draining extremely fast. When I put it on the charger, it charged very slow.
I put the tablet on the charger while I slept (6hrs), the tablet did not even charge fully. Only to 88%.
Anyone have battery drain or slow charging issues?

it's possible you have a bum unit. are you using the supplied charger and cable? some cables aren't high enough quality to sustain the higher charge rate and of course some chargers don't output enough power.

Yes, I am using the 2 AMP charger. I have it fully charged now. I am going to test it for the next day or so and it see how it performs. I will report back.

Mine also seems to charge really slow and drain way faster than my 2012 model. I noticed that the AC adapter gets really hot. I've tried with two USB cables and no such luck in improving anything. I don't know what's going on here. I need to some objective comparison testing but this just doesn't feel right to me.
I couldn't get to 100% on the initial charge until after I turned it on. It kind of just hung there in that 88% area.

}

so far I'm at 1 day 6.5 hrs with 5.25hrs screen and at 38%. not ag good as the old note, but the old gn101 wwasn't as purdy!

Charging and drain
Mine took a charge over night but the battery drains fast. I noticed that the auto brightness is set way too low. Perhaps that's how they got the claimed hours of use.

It does charge pretty slow, I'm surprised they didn't include a micro usb 3.0 like the note 3. I noticed last night that when I was plugged in to the included charger and streaming a video from chrome, it actually drained battery rather than charged. Even using it with lighter tasks significantly slows down charging, making it almost a requirement to charge it overnight.
It drains relatively quickly but if i can get 6+ hours of screen on time, between that and my phone it should last me more than a day of heavy use.

until the battery drains to 80% it's at trickle/slow charge. below 80 it charges full power. mine took 3.5hrs from 20 to 100. it took 2hrs 20 min to go 20 to 80 then 1.5 hrs for the last 20%.

Charging and drain
I noticed it drains quickly for the first 15 or 20% but lasts much longer after that. So I can only think that it's not reading the charge evenly.

I experienced a similar issue today. Had it plugged in overnight and most of the morning. Went to unplug it earlier and it was frozen at 83%. That was after about 12 hours of charging. I plugged it in around 40% last night.
The first two nights charged to 100% fine.

when i first got the note it kept getting stuck at 64% but the next day i charged it completely.
this has definitely got to be the reason one of those reviews said it's 7hrs to full charge.
i haven't taken the update yet so i'm assuming the some of you guys have and it's not changed anything. i haven't had any issue yet, but i also haven't had a need to recharge yet.

Old thread, but I am running into two issues:
1. I agree on the drain, but will use for another week to see how things go. So far the battery drain is considerably more than the iPad 4 and Dell 5130.
2. I can not find a spare cable that will allow slow charge through a computer USB. Cables allow MTP, but there is an X on the charge symbol. I tried charging while asleep and when shut off and same result. Not charging.
One of the reasons I got this was not to have to rely on keeping the charger with me like some other Android tablets.
