my captivate is v2.2 froyo rooted w z4 and lagfix, My stock battery barely lasts me through a night at work,
I ordered a 3500mah battery from ebay and when i received it I charged it overnight with my phone off....
The next day was a miracle! Battery stayed at 100% for 2 hours, by the end of the day I still had 60% battery left!
I read that the first couple charges need to be cycled so i tried to drain the battery by playing a movie over and over with screen brightness and volume at max.....
the battery lasted forever, after getting it down to 7% I charged it overnight- sameway with phone off, but now nomater what i do it only lasts the length of a stock battery.
I tried unplugging,plugging back in, phone off , phone on, waiting hours after it says 100%(on charger overnight) and tried ac and usb charging, but it just isnt seeming to charge all the way.
I was going to buy a second extended battery and an external battery charger but all the external chargers i see on ebay say are only good for li-ion batteries up to 2000mah, plus i had to modify my otterbox defender case to support my new battery and it would be a pain to have to take case apart everytime i swap batteries.
Ive been reading for days about what to do to no avail, all the external chargers i see arent rated for 3500mah capacity and I wouldnt mind flashing a custom rom that would support extended battery charging but the more research i do the more confused i get.....
Is there a kernal out there that is stable and supports charging these batteries with no bugs or issues????
What custom rom would be best?
please help......
any info is greatly appreciated
there is no such thing as a rom that supports extended batteries
the phone does
the chargers ALL work for the extended batteries there is no capacity rating limit on them. they do have a charging rate but it is around 350 to 800 mA/H and the batteries are acutally around 2500 mA so devide 2500/500 is 5 hours to charge.
[Review] 3500mah extended battery pictures heres my review - and would have been a better place to post and ask.,...
Cheap Chinese Battery Charger heres my charger. works fine.
[Mod] Battery Charger - USB Upgrade Mod heres my charger mod to charge faster thru USB. 800 ma/h so under 3 hours for extended,
charging on the wall charger or thru the phone takes longer than a regular battery.
charging thru the phone on USB is faster with the official samsung or with a hacked usb charger like above
i get upto 60 hours out of my battery. - under volted properly and custom kernel options..
you may want to wipe your battery stats. but i switch back and fourth no problem.
or your battery has a bad cell. those extendeds are just 2 batteries linked together.

there as an app in the market to wipe battery stats I forgot what its name it might be helpful to you since you're on stock froyo. probably your phone battery stats was in line with your oem battery so to maximized your extended batt you will have to wiped out the current battery stats for your phone to adjust to your new extended battery. I will post the app name later if I could find it. since you are rooted it will be of use to you.
edit: ok I found the app it's called battery calibration by nema download it from the market give it a whirl and observe how it goes..
i remember reading about such an app for rooted phones on a different forum but someone replied saying that it would wipe battery stats but still wouldnt help since the phones stock software is written to only charge a battery to 1500mah then it stops charging.....
Do u think it would work or am i screwed unless i flash a new kernal?
would be worth a shot.......
Is it best to wipe battery stats when extended battery is drained b4 charging.... or when fully charging .... or does it matter?
thanks guys for the fast responses!.....
so any of the chargers that fit my battery should work then.... they have the same specs as yours... so i will go ahead and order one for now,
I guess the surest way to know i am getting full charge would be to use the external charger...
So an extended battery should fully charge in the phone with no issues? Ive read so many forums that say a custom kernal is only way to charge them 100% in the phone???
no.. to charge at 100% speed. and i havent heard of any kernel for that in the captivate forums...
ie using the official samsung charger (usb) will charge at full speed the one that comes with your phone is 750 ma/h. if you plug into a non official charger the phone will only let in about 350ma/hour through the usb. or hack it.
i have the usb that came with the phone.... so i will get 750ma per hour if i connect usb to computer only or it will charge that fast on the samsung wall adapter also?
the wall adapter only!
the phone has to see the official CHARGER to charge full speed. or hack the other CHARGER, other wise it charges at what it calls "usb" so charging using usb would be slower too. if you read the [mod] link above, or all the other times i said CHARGER above, you would understand,
alright....thanks bro
charging via usb from your pc will always be slower than using a wall adapter.
not true.
aftermarket chargers (not samsung) wont charge the phone any faster than the pc
....unless you mod it!
[Mod] Battery Charger - USB Upgrade Mod
unless the middle 2 pins of a USB cable or the charger itself has the 2 pins shorted the phone charges in USB mode 350ish mA/h with the OEM chargers or a modded charger it charges in "AC mode" upto 1100 ish mA/h
the charger that comes with it supports this mode but only 750mA/h max output.

Hello people,
I bought a 3600mAh battery from eBay and just received it couple of hours ago.
So I plugged in the charge cable... and its been a few hours but the battery level still shows as 0%.
Have I gotten a defective battery, or is there something I can do?
Look forward any comments...
Jay.
nowadays I have seen many of this questions; cradle and usb cannot charge a battery like that; I'm using a 3400mAh battery on my pda; had the same problem.
but it works great with charger.
no, i think usb crade should still charge the extended battery, that is, if you can actually fit it in it charges a lot longer though, that's why i always use charger.
Is that made in china?
I have even seen this on my 1490mah battery. I couldn't keep the phone on and charge at the same when the battery was depleted to zero. I had to turn the phone off and let it charge for about an hour and then it would charge. Don't know if its the same thing for you but you may want to try.
Hi, i was wondering if there are any 'super' or 'turbo' chargers for phones. Chargers which charge up the battery faster.
I am going to get a 3000mah battery for my desire but i remember reading somewhere that they take ages to charge up.
My current desire has a charging problem, and does not charge at all at most times, even though charger is plugged in it stays at zero% charge.
Try Battery Monitor Widget. There you can see how many mA your charger puts into your device. You can't charge batterys too fast. There is a limit given by the battery. There is also a difference in chargers. You find them in the technical data.
Remember the charger is in the phone, the thing you plug into the wall is just a power supply.
Certain kernels will charge faster than others as well. Look for a fast charge kernel.
try different kernels
So that basically means the "turbo chargers" that they sell in the stores are a crock?
i will try it later.
battery charger
I have purchased in the store the battery charger, and spent two years no problem, it should be in there you can find what you need.
My change to a glitch kernel not only made it much faster, but the battery life seems better as well.
Sent from a glitched cm7 fascinate.
Charging via power supply plugged into power sockets is definitely better than charging via USB cables. Also, check out for cases for your phone which are capable of charging it too. I have seen some of those available for iPhone.
Thanks, I changed kernel and it started charging up.
I bought a new dock for my phone anyway.
So I just ordered this charger and it charged my phone from 4% to %100 percent in exactly 3 hours!

Wow, what a great improvement over stock which takes 6+ hours. This makes me believe, that even though the stock output is rated at 1000ma and this charger's output is only rated 700ma that this charges works correctly!
If you have a 1800mah battery and you charge it at a rate of .7A, it should take it exactly 2.57 hours to charge, (1800/700). With stock it should take less, because 1800/1000 = 1.8 hours, but it takes 6+ hours to fully charge! Something is f'ed up with the stock charger or phone's software...
Yeah. About that. I just got my E4GT yesterday and noticed it does charge extra slow compared to my O.G. Epic.
My wife stayed with hers, maybe I will try charging my phone on hers. I wonder if that would make a difference...

At first my charging was extremely slow but now it'll charge from 2 to 100 in under three hours

I use the Palm charger from my TouchPad. Will go from dead to fully charged in about an hour and a half.
What's you TouchPad charger's output in mah? I think I might have to splice into a spare USB cable and check how much current is actually used by phone when on stock charger...pretty sure it is nowhere close to 1000mah.
2000mah is the output from the TP charger.
According to BatteryMonitorWidget, it estimates avg mA charging at 270mA using the stock charger that came with this particular phone.
I have my original charger from my Evo 4g and have noticed that it charges my phone a lot faster then the stock one that came with the phone. :-( weird

That sounds about right! I'll see if I can test this with my AMP meter tonight and tell you all for sure on stock vs new samsung charger that I've got.

Yeah, at 2000mah it should charge in less than one hour...I would say your actual charge current to be around 1200mah...
i would be careful with these chargers.
i have dealt with a lot of Li-Po's in the past and there was a formula to how fast you should charge them.
i imagine it is the same deal with Li-On.
charging outside such formula could kill the life of your battery or worse.
Seems like i must have gotten lucky as a ton of people are having problems with their phone or chargers.
I just charged my battery from 0 to 100% off the stock charger in 2 and a half hours and i also havent gotten any of the dodgy input problems using the phone while charging.
I went back and took a longer look at the battery history when charging. When starting the charge at 65% it starts off around 828mA, then 540mA, then 360mA, so it looks like (as expected) the phone knows how much current to pull to charge the battery safely and it adjusts based on how full the battery is. Not saying it does this for the charger included with your phone, but that is the behavior for the charger included with this phone.
These are all estimates provided by Battery Monitor Widget because there is no real-time mA current meter in this phone (according to the author)
Ordered one of these. Stock charger takes a lifetime to charge the phone.
My GF got Nexus S 4G and it's stock charger also takes 6+ hours to charge, so there's something wrong with the chargers I guess...
The pins on this charger must me different than the stock charger. Just because the stock charger is rated up to 1Ah doesn't meant the phone or batteries circuitry allows that much output. The resistance and length of the USB pins on the cable are what determines the output of the charger. Simply using a different USB cable with the stock charger will get you faster charge times.
Using a 2Ah charger will get you nowhere, the circuitry doesn't allow that strong of a current. Just a bit of an FYI. Save your money and save your phone, use a different USB cable.
Also, how is the charge time holding up? I doubt you're getting a saturated charge with that charger.

Ive dealt with 1,2, and 3 cell lipos ranging from 150mah to 5000mah, and every one of them either say to be (or ive been told its recommended to do so) charged at 1C. so a 500mah battery should be charged at .5A, 1000mah at 1A, 5000mah at 5A, etc...
my lipo charger displays a bunch of info as the battery charges and it definitely drops the current as the battery gets closer to being fully charged. if its the same with li-on then I would imagine that .18A should be the most you would charge this battery, but Id rather it take a long time because unless things have changed recently, doesnt the slower you charge the battery prolong its life cycle as well as extend how long it lasts each charge? I only charge mine at night when I am sleeping so who cares if it takes longer than an hour. if I get into an emergency situation I have the cig lighter charger and in the worst case I even have one of those crank flashlights I can use to charge the phone in the event my car battery shorted out or something...
Is it me or does our phones charge super fast?
I drained it to 0% (let the phone die by itself while watching youtube)
Then I plugged it in at 8:05AM this morning.
At 9:05AM it was at 45%.
Pretty impressive.
(Once charged to 100%, should I wipe the battery stats and drain down to 0% again? This is how you would calibrate it correct?)

If you are getting incorrect stats then yes, clear the battery stats. The best way to calibrate is to drain, refill & repeat. Along the way when the battery is 100%, turn it off and charge it till it says its full again. Do this a few times when it's unplugged and you will see better life.
Speaking of fast charge.
I had 17% left at around 12:30pm today. Plugged it in while I went to lunch. Now at 2:50pm, just got notified that it's fully charged. Not bad at all.
Also, I had drained my battery when I received my phone.
How is that even possible!!!!!!!!!
It takes me 3.5 hours to charge it full!!!!!
Damn!!
I have two lines and this is my second SGSII aside to the one I already have...
I got this phone just yesterday and last night was my first full drain....today was my first full charge.
Shouldn't I go into recovery and wipe the batt stats?

I noticed today that the output from the charger for the SGS2 is 5V 1A and all other usb chargers ive gotten recently have an output thats closer to an actual usb port (4.5-5V 500mA) so that might have something to do with it.
My test pool on this hypothesis is quite small though so id be curious if anyone else can corroborate
I notice my battery charges much faster on an official samsung charger. Anything below 1V charges super slow. I want to try a rapid 2V charger but worried it may ruin my battery.. but on the other hand, AFAIK, some samsung car chargers charge @ 2v. They're called "rapid chargers" This is one of those times where you think AH any generic charger would do. I used to be in that camp. But I really found that the Samsung chargers are quickest. Also, they seem less likely to damage the micro usb port due to repeated use due to the fact that the Samsung cables tend to be thin and light weight as opposed to thick and bulky like some eBay cables. The thick and bulky ones feel like they'll give you enough leverage/weight if grabbed the wrong way and tear your micro usb port right off.
In the end, I love the Samsung chargers.
I just bought my T-mobile 16gb GSIII yesterday and I have Anker universal wall chargers for my spare batteries. Ever sine I got my HTC Sensation, I've used spare batteries and Anker wall chargers to get the better battery life then I would plugging up my phone in. I put ms OEM GSIII battery in the wall charger overnight and the indicator turned blue signifying a full charge. When I popped it in my phone it was only at 92% charged. I figured it was a mis-read so I popped it back in the wall charger. It wasn't a mis-read, the wall charger won't charge it to 100%. When I charged the phone by plugging it in via usb cable, it acheived a 100% charge. I'm just curious if anyone else has had an issue with the wall chargers.
From what I have read here on other threads, the battery is not supposed to read anything more than 99% once unplugged from a charger. I believe Samsung did this intentionally as a fail safe for the batteries.

As my original post states I'm having an issues getting a charge above 91%, regardless of how long the battery charges. The full battery indicator is solid blue and when placed back in my GSIII it reads 91%. If i was able to achieve 99% I wouldn't have had any reason to post my question.
I have read about this issue on mobile01.com as Im Chinese... This seems to be a common issue, it seems per my understanding is that the S3 has an intelligent charging circuit, which slows down the charge and current when its 90% or above, and will allow for a charge to a higher terminal voltage. If you use an external battery charger it will not charge it to 100%.
Are there any external charger out there that have this "intelligent charging circuit" I always thought the charge protection is built into the Li-poly battery.
I have the same problem since I got the batteries last week. The batteries work great but the anker external charger will only charge mines to 91%, its a known problem. I might get the Samsung OEM s3 charger and battery, that shouldn't have a problem charging these badboys to100%.
No external charger (that I have found) will take these batteries past 91-92 percent. You have to get the samsung factory charger to achieve this.
