By reading the display on the smart charger. :D It calculates current over time with tapering at start and end.

They were discharged to 2.90V no load and charged at 1.3A. Andida at 0.8A being the first, and I don't think it can handle more. None got warm, but I think the others can handle 1C and will be charged that way soon.

Edit: 1C charge is safe with these or any Li-Ion battery that's correctly labelled, but being the 1800 is 1200-1300, DO NOT charge at 1.8A or it WILL damage the battery or worse. Determine capacity first, then use that for a rate of 1C, or 0.9C max if unsure. Be safe.
[Captivate Accessories] CuriousTech:
Sorry if I was off topic.
[Captivate Accessories] sjavvaji:
has anyone weighed the 1800mah battery on ebay vs. the stock oem...there was a "seems heavier" comment and thats where that ended...
[Captivate Accessories] alphadog00:
CuriousTech - what smart charger are you using? Something for RC units but you built your own connector? Or is there one designed for phone cells?

Thanks for any info.
[Captivate Accessories] CuriousTech:
I have a Hyperion 720i and a couple older ones, but you can get this type of thing much cheaper for lower power charging, just stay away from the B6 clones on eBay. The connector is just the battery holder top half of a wall charger which is plastic and 2 spring clips, but really a couple of paper clips on a board would work. I just wanted to ensure a solid connection.

I wouldn't go through the trouble just for a 1 time thing though.
[Captivate Accessories] alphadog00:
Thanks - i thought as much, but I wasn't sure if there was something that was more phone battery specialized.
[Captivate Accessories] slvr00gt:
This is not an accurate measurement of the li-ion battery capacity. With li-ion battery you don't get exactly what you put in. Real capacity is heavily dependent on the discharge rate of the device, therefore the only real test of the capacity is measurement of the discharge over time. This is what i did in this thread:

http://xdaforums.com/showthread.php?t=906611

btw, there probably formulas to estimate the true capacity based on the intake, but you will need to know the relationships that vary for different batteries and only manufacturer knows them for sure

Out of pure curiosity I wanted to test something because it seemed my 3 test of 100% charge to dead had very odd results. Test #1: 12 hours, Test #2: 28 hours, Test #3: 46 hours. I flashed back to stock and then back to Darky's 7.7. Keeping in mind during the flashing I used the OEM battery and keep it charged as close to 100% as possible. Then switched batteries charged to 100% and did the battery stats reset process. 14-16 hours later using the 1800mAh battery, I'm not 100% sure the exact time, I picked up my phone after watching a movie with some friends (not on the phone) and the phone was completely dead. I did another charge to dead and got 27 hours. So far this is a near complete repeat of what was happening the first test runs. So in my theory it takes at least 3 cycles (100% charge to 5% or lower) for the phone to calibrate the new larger capacity battery. For all of you seeing poor results the first time you use it keep going as it should improve the more you use it.

Sorry for the lack of stats but last time I posted stuff people said it wasn't enough. So you can take my word for it or leave it..

Do I think this is a good battery? After the phone get calibrated to it... then yes! For $10 shipped to my door it's not like a its a large financial risk. If you are uneasy about buying this then don't, and just get a second OEM batter. If you don't like the lack of stats then buy one of these and test it out yourself and be all the stats hero you can be.
[Captivate Accessories] CuriousTech:
Quite true. The efficiency of the charge process may not be taken into account, while the most important value is the available power consumable by the device. The charge doesn't take into account any self discharge but also the discharge you're doing may not be the same varying resistance so it may not be perfectly accurate to expected usage either, but is the best possible method and does give a more accurate capacity and difference in capacity between different batteries and that's what we're after. Very nice work!

That being said, considering the fact that China doesn't have the manufacturing capabilities of Korea or Japan (or Taiwan for that matter), the possibility of a higher quality product coming from China is laughable, or should I say dishonest? So when you see a Chinese manufactured battery, or memory card or whatever that claims higher capacity or quality (or possibly even equal) than what the other countries can currently produce, well, not really possible which is what we already knew. LOL

In my tests, I may be pumping more into the batteries with the peak charger than the phone's internal charger, yielding a higher capacity as well, but at least we're backing each other's results showing that the OEM battery gets the best result so far.

Also, with the 1850 I did have some trouble. When it tops out it gives an open circuit error every time which is really kind of worrisome. So say you only get 1/4 of the charges, with more frequent charges with the cheap one, that's 4x or more the cost for the same use. It ends up costing more for worse performance.

[Captivate Accessories] Keland44:
this is a great thread
[Captivate Accessories] Keland44:
i did have a question for any of the battery expert guys out there

how likely would it be able to rig two batteries together or possibly 3 and get it to charge via mini usb let's say and then plug it up to the phone via micro usb kinda like a poor mans/diy portable power supply?

any documentation or tutorials or websites would be great if you have them
[Captivate Accessories] Dani897:
there was a thread to do this with typical aa batteries. also 9volt batteries. the aa battery method steps up the votage and has the ability to drain the batteries down fully. the 9v calculates to a similar capacity but cant drain the battery down below the charging voltage so the lower voltage batteries work better. the nice thing about the aa batteries is the small size of the final device but there is not enough storage to fully charge the stock battery unless you use 6 or so depending on the aa batteries and taking into account the power lost to heat.

to do the same thing with batteries for our phone would certainly have more storage and depending on how the path between the batteries and the usb port work you might be able to just use the batteries with no regulator which would prevent over draining as the phone would turn off at the point that the batteries were all at the minimum voltage. but i dont know how hooking a dead battery to a charged battery would react, there may be some reason the batteries are charged at a certain voltage and if you fail to fully charge the dead battery will that effect it in any negative way? using no regulator might only be viable for something that is always hooked to the phone and not an emergency charge pack, but i dont know for sure.

having some sort of regulator to provide the normal charging voltage would charge faster but would need a way to cut the connection when the charge batteries hit there minimum voltage.
[Captivate Accessories] Keland44:
good stuff any more details you would be able to give me?

how big or small do regulators run?

if you have the links to those threads about AA and 9v batteries I would like to check them out.

Joy... just received my not-actually-1800mah battery. :( I guess I'll try using it a bit and see how bad it actually is.
[Captivate Accessories] Jeffu:
Okay. This battery is terrible so.far. doing my usual emailing and web surfing in the morning and it is already 81% after being unplugged for about two hours. I did bump charge it, but didn't reset my battery stats. I'm wondering if that might be why the numbers I'm reading are dropping so quickly.
[Captivate Accessories] Autocratic:
The battery will get better after a few cycles.

I've been on this battery since Christmas. Going to run a few more tests and switch back to the Samsung battery and see what differences i get.

[Captivate Accessories] xThe Enforcer:
Interesting topic OP. I'll have to try this out.

Thanks
[Captivate Accessories] Jeffu:
Came home 12 hours later with 25% still left, which surprised me a bit. I had my original battery on me expecting to have to replace it at some point. I was needlessly checking e-mail and surfing a bit more than usual today as well.

The drain seems inconsistent at times; regardless I'll just keep at it for a while and see how things go.
[Captivate Accessories] Dani897:
just got mine yesterday. shipping took quite some time but it's here and so far good results. normally i get 25hours. right now i have 10hours and system reports 71%. not shabby. will it go on like that? no. but it is atleast as good as the stock battery. i feel satisfied but i will have to test it further to draw conclusions. usage varies.
[Captivate Accessories] nappent:
I've had this battery for a while now. Here is a couple of things to know about, based from my experience. I claim to be no expert... just reporting what I've learned and seen with this battery.

(1.) The first two charge to death (5% or lower) cycles you are going to see a 16-24 hour battery life. It's not until the 3rd charge cycle are you going to see the 40-50 hour battery life. No one knows why it's that way. Even with a battery stats reset. I believe it has something to do with the phone adapting to the voltage characteristic of the new larger battery. I know people have tested saying this battery is junk, but I can honestly say it far exceed my OEM battery from my experience. This battery is coming from China, which does produce good stuff, it just that they are not consistently making good stuff all the time. So those that are seeing bad results may have just gotten a bad battery. That’s my theory. Just make sure you try at least 3 charge to death cycles before you call it quits.

(2.) When your battery get to 25% or lower the actually life left maybe misleading. On the OEM battery when I would get to that level I knew I have maybe 2-4 hours left. With this larger battery I've notice that I typically have another 6-8 hours... sometime even 10 hours. So it can appear that your phone drops rapidly to 20-25% but then holds there for a while. This seems to be the norm. I imagine over time the phone will continue to adapt and this issue will go away…. but I could be wrong.

(3.) Charging Voltage can be high. I can't confirm this, but others have said that any charging voltage over 4.2v can cause damage to your phone and battery. If you are using the Circular Batter Indicator or Juiceplotter app keep a eye on the voltage. I notice during charging that it can get up to 4.21 – 4.23 volts. So what I've been doing is preventing it from charging more than needed. Once the phone hits 100% I unplug right away. So you might want to say near you phone when charging so you can always hear the sound when it's done. You might want to avoid leaving you phone charging all night long. I can't say for sure it will cause damage but the last thing we want to do is risk any damage with our beloved phones.

(4.) The only thing I haven’t gotten to test is the battery temp. Right now I’m up in cold rainy Seattle, WA so I can’t say if the battery ever gets warm. With many of us using cases on our phone I imagine we might run the risk of the battery running too warm if the phone was heavily used or left in a warm climate. So that might be something to keep a eye on if you live more to the south. Making sure you don’t leave you phone in direct sun light and or in a car is obviously the best way to keep the phone from getting to hot. Maybe in times of heavily usage to take the case off so you can physically feel if the phone is running too hot if you got a full screen app running and can’t see the temps via other apps.
[Captivate Accessories] CuriousTech:
The lithium gel is slapped between the anode and cathode in a sort of neutral state (actually it already has a charge), and during the first few cycles it polarizes creating a more optimal storage when complete. Hard to explain. Also it can crystallize if you leave it mostly discharged for too long. Storing for a long time fully charged is bad too of course.

Don't worry about the 4.23 volts. That's the absolute maximum for this chemistry and is regulated by the charge circuit, and is safe. Anything more than 4.235V or 1C (cell capacity / mAh charge rate) is unsafe. That's what caused older cell phones to go up in flames with cheap Chinese batteries. Say the OEM battery is 1000mA and the phone can charge at 1000mAh (1C) and you place a 500mA battery in it, it heats up damaging the cell, which then explodes now or during discharge. The Captivate charge circuit most likely has a max of 1000mA which is below what we've determined the true capacity was for most of these plus it has other safety features.

So basically, if you watch the battery temp while charging, the one that gets hotter at the end of charge with the same charge current has the lower capacity. :) The phone/charger also monitors the temperature and will stop or reduce current as a safety measure until it cools, so if it seems like it's taking longer than it should to charge and feels hot, that's why. It's employing that safety measure.

I got mine in the mail finally...

Benchmark:

100% down to 5%

12h 56m since unplugged.

4h 25m display time (Angry Birds, Andor's trail, Slice It)

3G (no wifi), GPS and BT enabled

I will bump charge the new battery and drain it till dead 3 times before I do my full usage test.
[Captivate Accessories] ChaoticKinesis:
I'm wondering if you would consider the above to be good or bad time, given your experience with your phone. In my 6 months of use (got it on release day), I have not once seen anything close to what you indicate. I don't think could get over 4 hrs of display time on a full charge, let alone over 13 hours of use. Playing Slice It is the worst, where a fully charged phone would probably die after about 2 hours of play.
[Captivate Accessories] joeybear23:
That is pretty good for me. I have had my phone last over 48 hours multiple times, but that is always with no use at all. I didn't see display times of over 2 hours until I started using Speedmod and Firebird kernels with the recommended ULK Tweaks set. I don't know how a kernel can make your display use less power, but these two seem to.

3G (no wifi), GPS and BT enabled

I will try to run it a few more days and see if it improves... if no change, it looks like it is really just a semi-decent backup battery.
[Captivate Accessories] ladiesgod:
I ordered one of these batteries. My question is what do I do first?

1) Charge the new battery as received with phone on until 100% then let it die?

2) Without charging first, use the phone with the new battery in it until it dies then charge to 100%?

Thanks!

That would be some interesting data. I've been using the better batteries mostly, but tested the cheap one the other day and saw 1238, then 1207 after maybe 10-15 more cycles from I think it was 1400 last month. Mine usually shows higher than slvr00gt's tests and can vary some. I wonder if we can come up with a little data on how fast a few of them degrade or how many cycles before they reach unusable. Like 500mAh would definitely be past time to drop them in the recycle bin.

I'm currently running CM7 with HSPA+ enabled and some fairly decent use and I get maybe 10 hours-ish on it. I really need more since I walk to/from home and I can't always get any extra charge in 8+ hours.

I'm still running the stock eclair. A few bugs just drive me nuts and I'm wondering if they've been fixed by samsung yet in the JL4 and 5 releases.

1)The navigation resets my system sounds to full volume.

2)There's an issue that when I'm in different time zones and enter events in the calendar they are "off" by the amount of time difference. I.e. I'm in the east coast now and the events that I enter into my calendar will be 3 hours off when I go back to the west coast.

3) Something...not sure what, reduces my notification volume to about 20%.

Firstly, I searched the forum but I surprisingly couldn't find a matching post! I don't think I am the first user to have the following line of thoughts...

The Armani version of our SGS has a stronger stock battery (I assume no cheap china thing), therefore:

1. Does it fit in a regular SGS?

2. Where can I get one? Officially from Samsung?

3. Does anybody already own one? ;)

The review is very positive. The reviewer states he would rate the phone a bit higher than the standard Galaxy S for buildquality and speed. The phone lacks FM-radio and a front facing camera. But it's not a deal breaker for the reviewer.
