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.

Hi all,
I recently purchased a Momax battery as a spare battery along with a cheap wall charger (from China) that charges only the battery. Unfortunately, it takes 7-8 hours to charge which is a bit too long for my liking, definitely when compared to the 2 or so hours to charge the battery in the phone.
Does anyone have any recommendations for a separate battery charger? One that actually charges the battery within the same time frame as if it were being charged by the phone...? I was looking at the Momax Smart charger, however am unsure if it's performance will differ from that of the charger I already have.

Hi all,
I've read, I've searched. Both here and on google and haven't found anything so far.
Does anyone know if there is a desktop cradle that charges the device with the standard battery installed while also having a spare port in the back that will charge or accommodate the (for example) Hyperion 4200 MaH battery?
I found a few cradles that will accommodate the regular battery in the back but they're all slots. Years ago, when I had my Evo, there were charging cradles that also had the capacity to charge extended batteries, just trying to find something similar.
I would like to find something like this because I have enough cases that will accommodate the standard battery, but I also carry the extended Hyperion battery with me with their back case in case I run low. I'd like to know that the extended battery when I pull it out of the cradle in the morning has a full charge and I'm not walking around with a discharged battery.
Any help or advice would be most appreciated.
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.
The battery of my new note 3 neo is different from the battery of my galaxy nexus,
It's 3.8V instead of 3.7V.
1) I am wondering if can be a problem if I charge Note 3 Neo with an old standard charger for Galaxy Nexus.
2) The Note 3 Neo charger is 2Ah, is it better if I charge the battery with my old 750mAh lipo battery charger??
Thank you.
While, it may seem to work, it is not recommended to use a charger for a battery of different configuration, as in the long run, it will damage the battery.
i think you should avoid using other chargers ....firstly its gonna take forever to charge from that charger because of its capacity secondly i have noticed a strange thing that when i connect my phone to some of the older charger, my battery starts to decrease over the time instead of increasing....its like the charger is sucking juice out of my phone....seems strange but thats what happened with me?...so avoid....
