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.
....
.......
....
ya.....
I've notice many ppl discuss about their aftermarket battery were unable to
reach 100% when using standalone aftermarket charger.
Just to point out that the S3's battery is using 4.35v cell instead of the usual 4.2v cell.
Most standard charger stops at 4.2v thus they'll stop at around 90%.
If you're looking for standalone charger. Best to look for charger rated at 4.35v.
(I rooted and change kernel to undervolt the CPU. the result is excellent, anyone who want longer run time should do it)
Every charger is 5 volts. The phone sets the charge voltage, not the charger, which is 5 volts.
The OP is referring to the voltage of the battery cells, not the USB charger (which is always 5V). The battery on the GS3 is in fact a higher voltage than most other phones (like the GS2). If you use an offline/standalone battery charger that does not charge to the full voltage of the GS3 battery the battery will show about 90% charged when you place it in the phone.
i wrote a review a few days ago on a stand alone charger i bought.
so far no problems with it charging my battery to 100%.

Hello ,
asking about my anker white charger i got with the tow anker batteries
can i charge samsung Extended Battery 2000 mAh without any problems with it ??
i would like to know before i start to use it normally
i used to use it with my anker 1900 batteries
but what about samsung Extended Battery 2000 mAh ?
it's recommended or it will make any problem
Anyone ??
i still need help plz
No one even tested it ?!!
Sent from my GT-I9100
As long as the charger outputs the same amount of voltage as the battery have, it should be good. And as long as charger outputs less than 2 amps to the battery, you should be good to go.
I am already using another type of charger without problems. But you should use alarm or remember when the battery will full charged to remove it from charger.
sorry for my bad language
Thanx a lot
Hello guys,
i'm using galaxy s4 i9500 n i just bought anker battery 5200 mah and 7600mah
1. How long should i charge my battery anker 7600 and 5200 mah using original samsung charger ?
i charge each anker battery from 10% to full about 2h 30m and the icon battery was already 100% .
2. Why it's same time when i charging my original samsung battery 2600 mah ?
my gadget doesn't rooted yet.
Hi guys,
I'm writing because I have noticed that my battery performance change if I use a regular 2A charger.
With Pixel stock charger, which implements fast charge, sometimes battery drain is fast after stopped charging. For example, from 90% to 85% in a ten minutes.
With a regular 2A - 5V charger, the discharge is more regular, and I have also noticed that the battery life is better. The problem is that it takes a lot of time.
Has anyone noticed the same?
