3500mah extended battery, charger vs kernal - Captivate Q&A, Help & Troubleshooting

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

XDA II, batt. help..

Hi, Need help.. Is it normal for O2 XDA II to turn off at below 40% batt. life? it turns off for atlst 4mins. then turn back ON again and if u try using it again, it turns off again. Is this some kind of there safety features so that batt. life will not be drained? thnx in advnce..
why are you letting it get that low?
you have to remember it is more than a phone so to preserve your data it does shut down if the battery is low, but the standard battery (1300 mAh) isn't vast and if your walking about with the screen on all day it will drain very quickly turn the screen off so its not running the battery flat and it should be fine OR buy a high Ah battery as I did for my XDA IIi from HK cheap as chips and I can go two days easy without charging
It only goes for about 6hrs.. dont know y, yup i kept on turning off the screen. wat Ah capacity did you buy? mine doesn't go long for a day, kept on charging it every day.
3600 mAh if I leave the screen off it lasts about 48 hours comes with a new back cover that while a little diffcult to shut it does and covers the battery fine
think this is the link
http://myworld.ebay.co.uk/battery_centre/
it cost £9.99 plus I think it was £4.99 P & P
Thnx owl, maybe the prob. is with in the batt., i'll try to buy new one..
I just had a replacement 3600mAh battery from a retailer here in the UK (Ebay) as the first battery they gave me was faulty. This one seems to take forever to drain
A std 1300mAh OEM battery should last a couple of days with the radio/Phone on but screen off in standby mode.
The 3600mAh battery should last the best part of a week or longer before it needs a recharge if left on standby. If yours only lasts for a couple of days then you have a faulty battery because yours is doing the same as the faulty one i had, which wasn't even lasting as long as my OEM 1300mAh battery.
I'd get the retailer to exchange it.
Hi!
I'v just bought 3600 mAh battery at http://myworld.ebay.co.uk/battery_centre/ for my xda 2i.
But instead of original 1300 battery, charge indicator shows only 100% or just 0.
Is it because of new battery and i simply need to fully charge and discharge new battery 2-3 times or is it problem of ppc?
Thanks in advance for answer, Gleb

Dead Battery?

The battery in my SGS will not charge. I have had the phone since September and have had the phone replaced in December, so the phone is 3 months old, but the battery is about 7 months old.
About a week or so ago the phone started to not charge well. It would take upwards of 6 hours to charge from about 50%. Last night I plugged the phone in and again, it took about 6 hours to fully charge and the charged tone went off (it woke me at 5:15 am). I unplugged the phone and within an hour the battery was down to 38%. I had it charging in the car for a couple of hours and it did not charge at all even though the charge indicator was on. When I got home I plugged it in and turned it off and it has been charging for a hours now but the battery will not charge at all.
My phone was on stock JL2 with the SpeedMod kernel, but I flashed it back to stock JL2 with the stock kernel when I got home.
Any ideas? Is it normal for these batteries to die after about 6 or 7 months? How good or bad are the batteries sold on eBay, the ones where you get two batteries and a charger for about $10? I'd hate to have to spend $40-$50 bucks on a new battery. I paid $500 for the phone and have had a lot of problems with it.
Thanks for any help,
Ian
Try to wipe battery in CWM. I hope it will help
I did wipe battery stats and it didn't help.
Maybe you can try this:
1) full wipe first (factory reset and flash new).
2) charge until full
3) use until it shutdown by itself
4) charge full again
That's what I would try before buy anything

The battery will not charge.
Battery will not charge try another battery to see if its the phone the charger or the battery is your only choice .

Thats a genuine battery .

What is the voltage range the SGS works at? My battery reads 2.99v. Should the phone still work at this voltage?
*Edit*
Well, I made a desktop charger from an old cell phone charger, a couple of brass nails and a block of wood. I charged the battery for about an hour and the voltage now reads 3.14v. I would presume the phone should work at this voltage since the normal voltage is 3.7v and 3.14 is less than a 20% drop.
I guess it's my phone that is no good. It's back to the service center for me.
Thanks,
Ian
Am other idea: You checked the charge cable?
Sent from my GT-I9000 using XDA App
Anyway, I stripped the wires on an old charger and connected it directly to the battery pins on phone and bypassed the battery and the phone boots, so I guess it's the battery.
Does anyone have any feedback on the eBay batteries. The ones you get two and a charger for around $10?

Any problems cycling 3 batteries?

I bought a couple extra batteries for my 9000M. Are there going to be any problems draining one battery, then inserting the next, and so on? The extra batteries have to be charged in an external charger I believe. I haven't put the new batteries in the phone yet.
Thanks
there should be no problem
im doing the exact same thing
original battery + 2 1500 mAh batteries from HK
i can tell that the original batt does have extra juice but not a real big difference
running thru 2 batteries a day on lot of screen time (involves gaming + watching movies and such which really sucks up the battery)
i use the ones i bought first since i see the original having a little more juice and keep it for real emergancy situation since i know it will last longer
usually when plugging a new batt in (either of the new batts phone starts with 99-97%) and lives to 10-3% before it shutsdown
but when i plug in the original it starts from a 100% which is good
no problems for the past couple of months and all is good

3500 extended battery decline in performance

I purchased the 3500 extended battery about 4 months ago. It was a great battery. It lasted me all day & then some off a single charge. Now it's not lasting as long as it used to. I'm having to charge in the middle of the day now. I put my original OEM battery in, & I'm getting better performance from it than with the 3500 battery now.
Anyone else experiencing less than stellar performance from the 3500 battery after having it for 4 months or longer?

I have the 2150 OEM, I can only suspect some reasons why
1) Cheap battery that does not hold charges well
2) You are draining the battery down to 0% a lot, killing the ability for it to keep a charge
3) Your phone is not calibrated properly so it shows it is charged to 100% but in fact it may have only charged it much lower

1) It's a Seidio brand, not some knock off, so it should be of good quality. It's been working fine up until the past month or so. I've had it for over 4 months now.
2) I've never drained the battery down to 0%. Contacted Seidio and they suggested that I let it drain to 0% for the next 4 to 5 charges, along with charging it an additional 2-3 hours after a complete charge. I'll see if that helps.
3) I've always had to bump charge it. It helps in making it last longer.
I don't think bump charging is helping the longevity of your battery. Not saying it doesn't last longer on a charge, but that it isn't good for the battery's overall lifespan.

Draining all the way down and overcharging it are the biggest ways to kill it off. The Seideo and most other batteries I think have a fail-safe for draining it all the way down, cutting it off early before it actually does.
This article is pretty helpful about your battery, if you haven't had the chance to read it, it may benefit you:

Bump charging did it.....
Where's ma rosie at?
I have been using the 3500 for about the same length of time you have been. I haven't really noticed a drop off in performance. Maybe a very slight drop off.. not much though. Still could get 2-3 days use on one charge if I wanted to.
I have the same issue with my 3500. I will try to re-calibrate it.
4 months seems to be pretty quick for a decline in performance like that. I would press Seideo to replace it.
You can try resetting the cells to how they were when it was brand new. All you have to do is completely deplete the battery of all charge (so it wont even turn on) then short it out with 3x the voltage (a 9v battery should work, make sure to keep the polarity the same) and fully charge it again, then it will be like new!
My dad (who is an electrician) found a guide for this on ebay and bought it just for the hell of it to see if it worked. We tried it on a battery I had for an LG VX8300 I had at the time and it worked beautifully, I've been doing it ever since!
I have no idea how this works, all I know is that it just does.

When ever you get a new battery you must condition it, exactly as sedio said full charge it, then drain fully 5 times. It makes the battery last much longer

I got some 3,500mAh cheapies off ebay about 6 months ago and they are holding up just fine. I always run mine down to about 5% then fully charge. I bump charge them about once a month.
Well of course... After I'm pimping how great these batteries are, one quit working! My phone would just shut off with a light tap against something so I pulled the black sticker off of the battery, pulled it all apart, found the loose connection, bent the tab to make better contact, and put it all back together. All is good again.
I recently purchased this same battery read tons of good reviews not sure how i feel about the bump charging after reading the article that was within this thread but all in all it is a giant leap beyond the stock battery now if i could just find a case that would fit around it
To the OP. If youre running a kernel with SBC (Superior battery charging [trickle charging] w/e you wanna call it) they're known to reduce your battery life. also you may wanna charge the battery to 100% then wipe the battery stats on your phone.
I have the same battery and I've found that the phone has trouble reporting the percentage correctly. It tends to make jumps of about 5-10% instead of a steady decline. I switched to the original battery and it did not have this problem. I've also noticed that clearing battery stats several times helps (most of the time). As far as bump charging goes, it's perfectly fine to bump charge these batteries. The worst thing you can do to them is discharge them all the way.
Clearing the stats and cycling the battery through the phone a few times should fix that. It does that (big percentage jumps) when it's poorly calibrated.

I second this. I have the same battery and its been off a few times. Battery stats get weird sometimes. It's certainly a better battery than the cheap Chinese batteries HTC uses.

Conditioning 3500 mAh battery

Just bought a 3500 mAh battery off of ebay. I was wondering do i need to condition this battery? If so what are the steps? I see conflicting info all over the place.
thanks!
Conditioning? Like calibrating?
Some batteries said to drain it completely first then charge for 8 full hours to condition it. That's why i was wondering if there was anything i needed to do to get the maximum amount of battery life out of it.
That's a great question. Usually I let it drain fully, then fully recharge. It's just an old habit of mine with new batteries.
usually when you get a new battery itll have some charge in it you need to power the device on let it drain completely till it wont turn on at all then let the battery charge 8-10hrs and you should be good.
