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.

There are lots of myths regarding lithium batteries.. some say you are not supposed to overcharge it (charge it only when it's running out)
Some say it doesn't matter since lithium can be recharged as much as you want and it won't deteroriate the battery's life.
Which one? Can I recharge my Touch Pro 2 every night before I go to bed and leave it until morning? or should I do it when it's running out to preserve the battery's life?
You should keep the device on A/C power as much as possible. So, it's fine to charge daily overnight. Every once in a while, you should let the battery run all the way out before recharging. What this will do is keep your battery meter reading accurate. If you don't do this, eventually, your device will "think" it has more juice than it actually does.

Ah thanks
So to cut the story short, recharge it as much as you can and prevent the battery ever from being run out
Nahhh, not fully true. Somewhere else on the site of batteryuniversity it sais that completely discharging the battery will reset it's memmory. This is usefull after a lot of charges and discharges (in the beginning, I think they already did this (you may hope).
(the memmory helps the battery know where his power is storaged and how much power the battery has left. But doing this frequent speeds up the battery 's lenght of life
In my experience
Enjoy your device and charge battery when needed/desired
Use it normal
Batteries have a duration of 3-4 years aprox, no matter if you charge it every night or leave it till it´s empty...
When battery fails you buy another one and so on
Just my opinion,
My experience with the battery life on my touch pro 2 is that I will keep the phone usually docked in my cradle on my desk when working so it's always on charge. When I use my battery I wait till it's about 40-30% drained and will stick it on the cradle again.
When I'm in my bed ready to sleep, I use the normal charger and leave it on charge over night.
Still experimenting though.

Do you have a cradle for your Rhodium ? Where did you get it ?
Check my battery thread, it will tell you pretty much everything about li-ion batteries and taking care of them

Hmm, first of all Li-ion batteries have NO MEMORY unlike NiCd batteries. You probably refer to resetting the reading gauge - which is related to device's capability of getting accurate reading rather than battery itself. It is recommended to let the device die once a month and give it a full charge to "recalibrate" phone's battery meter (not the battery).
But you should avoid hitting 100% battery mark as well as going bellow 30% as much as possible.
from my experience as a phone shop owner and owner of many many phones i always advise my customers and friends as follows:
1st charge 10-12 hrs. allow battery to fully discharge
2nd charge at least 8 hrs
after 2nd charge you can charge and use as you want. the initial 2 charges kick start everything and starts your battery cycle on good stead
never had any complaints!
Another thing, is it bad to use your device whilst plugged in?

its ok to do that as it will run off ac power while plugged in

The battery should be as cold as possible when charged. So if you are using the phone the battery power drains and is charged at the same time. Therefore it gets warmer than without.
Best for the battery is to be charged when the device is switched off completely.
I wouldn't consider that much of a problem, because you have bought the device to use it and not to live in fear that you treat the battery right
when plugged into USB and playing a game on my TP2 I got the message the device is using too much power, and it drained the battery even though recharging via USB. No problems when using AC adapter though.
Used my XDA Orbit 2 for 2 years now, and mostly charged at free will. Battery is still fine, so no special charging rules for me...
I noticed though, that charging over USB takes quite some time while charging over AC cable is done within an hour or so. When looking at my AC it has 5 Watts of output power, while the USB only has 2.5. That would explain your issue with the battery running out even when having the USB cable plugged in.

for some reason, everytime i charge my battery, it stops at 96%..i would then need to unplug and plug the cord back in to let it finish the rest..do i have a bad battery? i tried different cords on pc, wall charger, car...
not sure if it's because i installed something on my phone that might up messed up some reg files or damaged something..
anyone else having this issue?

I have posted some weeks ago the same problem.
It looks like a charging bug courtesy of HTC that i allready reported to HTC Spain, but they don't know what i am talking about
I know you probably wan't the most battery life you can get but this might be a good thing! I'm going to test it out soon!
If you read up about lithium polymer batterys, like the ones in our phones it seems to sugest that keeping the battery between something like 40% and 80% charged and charging more frequently for shorter periods of time rather than leaving it on over night will prolong the batterys life.
If you want to be really geeky and store the battery properly at any time, charge it to 60% and put it in the freezer (in a bag).
I'm not sure about these or any other phones but laptops didnt use to come with overcharge protection (Ithink most do now) meaning that when the battery charged to 100% it would just keep charging and fry it! This might be HTCs overcharge protection!
Cheers
Tom
i noticed if i do leave it over night, it goes to 96%, then i slide to unlock (s2u2) and then it starts charging again, and then it reaches 100%...

On every PPC that i have owned before, as soon as battery gets fully charged, it keep fully charged, and the power is taken from the wall charger/Car charger while you keep it pluged on.
Why you keep trying to trick us with those % , if you know that this Rhodium is a BIG BUG ???
Cheers
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.....
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.
my phone has cyanogenmod 5 installed on it, but it will not charge to 99%, it will charge to roughly 66%, than be completely dead after 30 minutes. I tried using 2-3 different roms, with the same result. I am using a usb cable to charge it, (still waiting on the ac charger), would this have anything to do with it?, or do i need a new battery
My battery died about 18 months after I bought it. Sounds about like what you are experiencing. Take it to a store and borrow a battery and see if it charges. But I would think you just need a new battery.

sorry, I should have followed up on this thread. It turns out, the charger i was using, which was an off-brand charger, was only producing 500ma. i bought an htc mytouch branded charger, and it produces 1000ma, so now it charges just fine and easily lasts throughout the day. thanks for the response though
