[Q] captivate and 3500mah extended battery, Help

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.

[Q] HELP Extended Battery not charging (unique and weird problem!)

Hi xda,
i have recently bought these 2x 3600mah batteries from ebay. I cannot post the link but they are from an ebay store called bravo-ex. Its one of those white batteries with red and yellow stripes. The batteries brand says RD, but i think its a generic china brand or something.
Anyways,
I was able to use the batteries a first couple of times. I managed to charge both up only up to around 65%.
Now i have this problem where the charging indicator is not showing properly when i plug my phone in. There is no battery indicator lightning sign or moving. It stays stagnant at 5%. Tried charging for hours and nothing changes.
When i try to charge with phone turned off the phone will boot back up to home screen, instead of showing the big charging battery icon.
When i plug in the usb cable. Battery section in settings shows status as Not Charging but the led light still comes on red so i know there is charging going on but the battery meter doesnt move!
I have tried the following:
- edit build.prop battery capacity to 3600
- deleted the batterystats (couldnt delete at 100% because i cannot charge beyond 65%
- reflash to stock rom 2.3.4 and kernel (it did work for a while but went back again after a couple of plugging and unplugging)
- switching back to stock battery to check if usb port is faulty. The charging still works!
- changing around between 3 pairs of cables and chargers
My system is
-R800i
- Rom: Elite Gamer v2.0 GB
- Kernel: Lupus v12 for GB
- I had my digitizer and flex cable replaced at a third party service center about 2 weeks ago.
Please help me i am getting desperate. It may be the batteries are DOA but both batteries being dead seems a little unlikely. I really love this little piece of gaming heaven. I would really appreciate if someone can give me any expert advice. Thank you!
-

i have discovered a weird and non permanent fix.
i have to swap the old battery and the extended batteries back and forth several times until the battery meter decides to show up on the extended one.
But it only works after like 10+ swaps and after few minutes of charging it goes off after like 10mins!
WTF!

I agree that you have wierd problem.
I would blame the charger, but you already test another one...
If i where you, i would measure voltage on battery after it stop charging with voltmeter. 0% should be 3.2V and 100% charged should be 4.2V. On both, stock and extended battery.
Also, measuring voltage at pins that connect the battety to see the voltage value (with battery removed and usb charger plugged in)
Or maybe contacts on usb jack on phone is dirty and can be cleaned with alcohol and cloath (with phone off and battery removed)
This is just wild guesses, i really can't say what is causing it

[Help Request] Charging issue

I been having troubles charging my S4 and I used the one that comes with the phone when you buy it and it charges completely but now I have a different one that's made by Samsung but my phone wont charge completely. I put it on the charger at 10 am and by the time I go to school its at 60 or 70 percent everyday,even when it's on airplane mode. Is there a way I can fix that? I tried wiping my battery stats and I also got Battery Doctor but that doesn't help either... So can someone help me with this issue?
Additional information:
Running Wicked Rom.
Stock Battery
Not even 2 week old yet.
I haven't dropped it at all.
No water damage at all.
Also charger is a 1.0 amp charger made by Samsung.

I'd consider flashing to stock and starting over, buying another battery, or another charging cable.

I still use the stock charger and cable that came with the phone and my phone charges at approximately 1% per minute (or even a little higher) when it is on the charger. If yours doesn't charge that fast try another cable (borrow one if you have to or go to the T-Mobile store and ask them to use one of their cables to test it for you). Good news is that even if your battery has gone bad you have a phone for which the battery is easily replaceable.

I have figured it out. I uninstalled a few programs that wouldn't let my battery charge completely. I noticed there were three applications running while my phone was on and those thee programs were running all the time without me knowing. So I Delete Battery Doctor, Clean Master, and Wakelock Detractor. After I uninstalled those, my phone was charging a lot fast and when I woke up today, my phone was at 100% and I was happy. I thought I would have to re-flash my rom.

Help Fixing Water Damaged HTC One V...

Please,anyone help me fixing my HTC One V. It was accidentally dropped in water,I turned off it immediately and removed the water as much as possible then I kept it in rice for 2 days.It is charging very slowly and it only turns on after plugging it to the charging socket.It takes 11-12 hours to charge to 60% and drains out in 3-4 minutes only. Please help me fix it.

Looks like something is draining your battery or your battery is broken. Open the phone and look for damaged components...

Thanks for the suggestion,Can the battery change will do the work ? I have taken it to the Service Center they said that they will have to look it if it's charging socket problem,and if it is then being its socket mounted on motherboard directly they will have to change the motherboard of phone and it will cost me a fortune to do that.

I don't think the problem is the battery, it's more likely some short circuit with the charging port, yes.
There are some replacement part stores for hov, I just found a charging connector: http://www.parts4repair.com/htc-one-v-dock-port-charging-connector/
When you look at the pics of the connector it seems to be soldered onto the mainboard, but it shouldn't be that difficult...

But,the phone charges with the original connector,I think it's battery problem,Is there any alternate way to keep it charged? I'm gonna check it but I am unable to open one phillip screw as it's threads are damaged.How am I going to open the damaged screw?Please anyone help...

If you already opened your phone, use hair dryer and lightly dry up your phone. Do the process for 3-4 times for about 2 minutes each.
You can check your battery with a multimeter, just follow below steps:
1.Switch off your cell phone and carefully remove the battery.
2.Now search on the label of the battery for its given voltage. Most batteries of cell phones are 3.7V
3.Place the battery such that its terminals face you.
4.Now keep the multimeter (either analog or digital) on DC Volt setting.It may be indicated with either DCV or just V and a straight line with 3 dots below it. In DCV (DC Voltage) also, there will be many settings like 2mV, 2V, 20V, 200V, 1000V. Keep the setting on the number above the actual voltage of the battery. It will be either 10V or 20V in most multimeters. An indication of ACV or just V followed by a curved line means AC voltage. Do not use this setting as batteries run on DC voltage.
5.Now touch the tip of the red probe of the multimeter on the terminal of the battery named ‘+’(positive) and touch the tip of the black probe on the terminal named ‘-‘(negative).
6.Keep both the probes touched until you see a stable reading on the screen of the meter. If the reading on the screen is more than 3.70 for a battery of 3.7V, then the battery is fully charged. And if it is less, then you will have to charge it with a charger. It should show a reading above the charge of the battery. If the battery is drained and showing 0 voltage or say less than 3.7, you will have to charge. If after charging for a long time, still it is showing the same charge, then the battery is faulty. You will need to buy a new one as batteries are not repairable. If the reading of the battery is below 3.7V even after charging it, your mobile phone will not switch on.

Thanks for the details buddy,actually when the phone is switched OFF and plugged to charger it charges and the LED indicator glows to green means fully charged and as soon as the phone is switched ON with the charger connected to it it charges again & again .Meanwhile the phone switches ON only when charger plugged on to the socket,It doesn't wake up on Normal battery condition.I am really frustrated with Non-removable battery type of this mobile.

Well,Thanks everyone for replying.The problem is solved after changing the battery.Big relief cause service center told me it will cost too much in changing the battery or changing the motherboard and I repaired it with very low cost watching youtube videos and a big help with XDA forum.

Correct method to install/calibrate new battery?

I just received my new batteries from Amazon.
http://www.amazon.com/gp/product/B00Q4NQQA0?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00
I charged it up in the external charger until it indicated full. When I installed it and booted, it said 91%. I ran it down to about 15%, then plugged the phone into the charger. Now it only goes up to 86%.
When I first swapped the battery, I held the power button for about 30 seconds then installed the battery (as recommended when flashing TX's Note port).
Is there a proper way to calibrate a new battery? Might I just have a defective one?
Thanks for any advice,
Mike

I recommend pulling it off the travel charger and putting it right back on. If the light changes within a minute it was full. If not... It wasn't. You can do the battery calibrate app but your phone will figure it out on its own.
My best advice is to toss your old battery and only use the 2 new matched batteries. The phone will have errors in battery percentage if it is calibrating batteries that have different discharge rates due to age/size.
In a perfect world only charge them on the travel charger
Put it back on to make sure it's 100.
Discharge to 0 or the point the phone shuts down every time as well
A few days and your phone will display correctly

The new MM has the option to turn off the fast charging, can't he just turn this off instead of trashing his charger?

Yeah. I wish we all had that option. I know some you have to plug in the fast charger to access the setting to turn it off.
