first of all im sorry if this issue seems to be redundant to all....
im a bit confused to some of the post on this forum regarding this issue...
(so please bear with me...especially to the mods out there)
i do have this battery and it seems that it wont even last for atleast a day...
is this normal for this brand of battery or 4800mAh battery?
how long is the normal standby time for 4800mAh battery?
i also have an original 1620mAh battery and it even last longer than my 4800mAh battery..
can anyone here help me on what to do?
is there anyone in here can prove that 3200 or 1620 is much much better than 4800?
and one more question...i also have a 2 spare 1620mAh battery....
one of it turns off at 75% the other at 21%....
i've tried resetting them both but no of luck..still the same..
is there any other possible way for me to use them and drain them up to 0% or atleast 10%?
thanks in advance!
3200 will last twice as long as 1620; 4800 three times.
However, this is given they are all the same manufacturer. Some batteries are better than others. Cheap eBay batteries are known to give problems - however I have had good as well as bad one's from eBay.
Also, batteries will wear out after a while - I think suggested time is a year or two.
I have four 1620's which last from 50 minutes to 3 hours (constant useage with backlight on). My 3200 lasts 6 hours.
I find that whichever (fully charged) battery is in Uni when I upgrade ROM, will give accurate reading. The reading becomes inaccuate (turning off a x%) when I swap for different battery.
ROM Upgrade & battery
so your saying that when i upgrade or change rom..
1. the battery should be at 100% charge..?
2. and the battery that i used when upgrading should be the one to be used until it drains to 0%? coz when i replace the battery thats the time it will shut off at X%?
is my understanding correct?
if i may ask...what brand of battery would you recommend for a 4800mAh?
and would you recommend 4800mAh?
ive seen DUKE NUKEM's post..he's selling batteries right?im planning to buy 2 pcs of 4800mAh....but the problem is i dont have a PAYPAL account and im a bit confused coz some say 3200 is much better than 4800..and some say 1620 is the best...
thanks for your help sir jonny....
Yes, you are correct.
I don't have a 4800, so can't comment.
Anyone else got a recommendation?
The main reason that people prefer one battery over another is due to the size. Most people seem to like the 1600 because the Universal is fat enough without having a huge battery sticking out the back! Other people may be biased toward a certain capacity because they bought a duff battery.
Personally I'll use a 1600 and carry a spare sometimes... unless I know I'm going to need juice (for a plane trip etc) and I'll stick in my 3200.
what to do on batteries shutting off at x%?
sir jonny do you know a way on how to correct those batteries that shuts off at x%?
coz what im doing is
1.charge the battery to full
2.put an adhesive tape to cover the second connector of the battery
3.then drain the battery using my UNI or using 3 LEDs...
4.charge the battery again to full
the problem is that it still shuts off at x%...
some claims that this corrects the problem..
am i doing the right way or is there any possible way?
ive seen some threads regarding this issue but in my case it dont work..
ive got 3 pcs of 1620mAh with this problem..
thanks again for your help...
Did you charge it with your original charger? If not, you can't get 4800 mah.

im always using the original charger....but if your talking about the initial charging prior to shipping of the battery...i cant answer that because i bought that battery from a friend...and it is a second hand battery..but he told me that he just used the battery once and havent asked about what charger he used.
I have done some efforts regarding battery capacity measurement Just lookup this thread: http://forum.xda-developers.com/showthread.php?p=5558383#post5558383
I would suggest stay away from the Sino Cameron batts. They simply suck. I have one 1650 and another 4800. Both not very up to stretch, especially the 4800. By all means it does NOT last three times as the standard batt. I'd say perhaps just about two times in reality. Perhaps not. I just keep seeing the batt level dropping fast. Plus the build quality is a real issue. Somehow the 4800 gets too fat and the batt cover cannot completely fit in the slot. Three times the size but just a little power boost. It's cheap, but now I regret having wasting money on them...
Then I switched to Momax. It's just a standard 1500. But it shines! Battery drains pretty slowly and stably (no sudden dropping). It's a bit more expensive than those crappy Camerons, yet it's worth the extra dollars.
Yes, right
It´s always better to go for the original one

If you want a good battery for your Universal, I will suggest you to buy a 3200 mAh battery from ebay, it's the best
Which brand of 3200 batt do you recommend?
I have 2 similar 3200mah batteries but to speak frankly, I used them mainly at home and when I go out I take 2 1620mah batteries with me. The 3200mah is simply too huge & heavy - since the Uni is a big phone, people may find it funny if they see the overal size especially when you are putting it near your cheek when receiving/making calls! You can check this link - the seller also sells cheap 1620mah:

Won't really effect it either way. Just make sure you fully charge that 3500 and leave it plugged in for 2 more hours after its green then disconnect and wipe battery stats so you can get the most out of the new one.
Lithium ion batteries are best stored at around 40% capacity.
Thanks Fellas!

Can you explain why? I would think leaving it fully charged would be best. You don't want to let a lith-ion completely drain, so perhaps the occasional charge up would be best (every 3 -6 months?)

No clue, I'm not a battery engineer. I googled it, 40% was the general consensus of the internet.
This is my first post on here,but I've been lurking for ages I just bought a Mugen 3200mAh battery from MugenBattery.com.I already know about not having to condition it(lithium ion),so I ignored the instructions about cycling it and plugged it in and used it right away,and at first it seemed okay for around an hour(I didnt use it at all up to this point,just left it there until I needed it).When I went to unlock my Vibrant from suspend(pushing on the power button),the phone shut off and seemed like it was rebooting...but it just had the first screen you see(the one with Samsung and Vibrant on it) blinking on and off,even when I plugged in the charger in this state,all that popped up was a battery that also blinked on and off.The only way to get it going again was to pull and replace the battery,and it went back on again...then did this all over again when it went into suspend and I tried to unlock it.All the while,the battery stated it had around 75% power,so I have no idea what could have caused this.I put my cheep chinese 2700mAh battery back in and all was well again,so I know its the battery,not the phone.Anyone else have or seen this problem before?This is the most expensive battrery I have ever purchased for a phone at $88.00US....I hate to think that a cheep($20.00US) chinese battery has better quality control than it....
i think you need to charge it for 12 hours first.

Thanks,you were right! An overnight charge of around 12 hours did it.This is the first phone battery I had to do that with to get them to just work at all.Seems to work just fine now Again,thank you!
Let us know how long the battery is lasting once you get a few cycles please!
Yeah, you should run the battery dry, recharge, run dry, recharge and after a few cycles your life should improve.
Will do,just need a few days to do it,its lasting a looooong time!

NO, NO, NO. PLEASE stop spreading bad information. This will HARM the battery, and will have 0 benefit. The only "benefit" you can get from this is that the battery meter on the phone's firmware will be calibrated to show a more correct remaining %. You can achieve the same by charging the phone 100% (overnight) going to clockwork recovery and selecting 'wipe battery stats'. Calibrated or not, the battery will last the same, regardless of what % left its showing.
Again for posterity, REPEATED DISCHARGING OF LI-ION BELOW 20% IS BAD FOR THE BATTERY, IT'S PHYSICALLY IMPOSSIBLE FOR IT TO GET BETTER.
I am having a similar issue with a battery that I ordered off of ebay. It's 3500mah.
When I plug it in it will turn off and get stuck in a boot loop on the vibrant screen, but if it is off then it won't turn on at all when plugged in. It has been plugged in for 9 hours so far and it doesn't even show the charging animation or anything.
Normal? Or is the battery defective?
Thanks.
Ok. After charging it overnight and still nothing, I'm going to assume its broken. Thanks.

Not to derail, but how much weight does it add, and how well does the back cover fit on that big Mugen?

...and it does get a bit bulky,weight goes up to about double the amount,but it is so worth it,and then some!!I went from 6 hours on the stock battery to over 18 with the Mugen,and thats with heavy use(full brightness/live wallpaper,etc.).If you dont have access to a charger outside your home,this is a great buy,and you know the quality is there,unlike the uncertainty of the cheep chinese ones.Highly recommended!
The OS needs to learn your new battery. Just takes time and usage.

I am not so sure about your information. This is what DHGate, a wholesale Chinese online store wrote about the 3000mah battery for Galaxy S [not MUGGEN!]
How to use a new battery:
1. First when you received the battery,. you need to release the power in the battery, just put it into your phone without charging.
2. After the battery power is out, please charge it about 12 hours in first three times.
3. So the battery will be actived. So you can just charge it about 5-7 hours when use in the further.
You can find the URL here:
http://www.dhgate.com/ems-free-i900...-back/p-ff8080812c87c8d9012c97f06d9410ea.html
I also recommend you to read the article "Everything You Need To Know About Bump Charging And Inconsistent Battery Drain" here:

So this a controversial matter, isn't it?

No controversies at all. Your info from the link is outright wrong.
Mannymal is correct on this one.
I also have this battery. By the time I got it, Team Whiskeys roms had gotten good enough to where I didn't need an extended battery for day to day use (stock battery usually has 30-40% when i go to bed), but I do use it when I travel, so I don't have to worry about using it like crazy. The battery lasts a long time, probably like 2 or 3 days if I actually tried to drain it, at least. And it's definitely adds bulk, but it's reasonably well made and feels sturdy.
My only complaint is that I sometimes cover the speaker with my finger when I want to silence it real quick, and it doesn't work with this because the cover's so far from the speaker. But that's just my weird thing.
Also, yeah, don't kill your battery. No es bueno.
What is this? How do I read?

I use a seido innocell battery and it works great after a few over night charges. I get about 8 hours average of talk time. The battery is pretty small compared to the one accessory greeks sell. Even though the ah battery ia twenty five dollars, that is like the entry level name brand battery, it will lady you a while longer than the cheap ones on ebay, but I don't knower about the ones on ebay although I do know about the one ag sells skies down charging after about 45 percent charging. The seido is charging pretty fast for me and is half the price of a mugen, the next battery I'm going to buy will be the nugent, not because I need it, just
Cause I want to enjoy it.

Hello folks..
I have a HTC Desire CDMA and I bought a Extended battery (3500 mAh to be exact) and this battery lasts just about as long as my normal battery does. It is thick enough to be 3 of my regular batteries, and it is alot heavier, so i know it wasnt a scam, plus there was good reviews... but, The only difference that I get with this extended battery, is that it stays at 100% for about 3 hours, and then starts booming down the charts on battery level.. I mean, i normally have about 25% at the end of the day with this extended battery, but i figure that it should atleast last 2 days on a full charge.... with it being 3500 mAh.. I mean, wow... Can someone help me? Im using a trusted stable battery saving kernel and rom.. so I know that's not the problem..

Do you have a custom rom? Try to download SpareParts from the market and unplug the charger when it says "charged". For my Samsung i5500 and a cyanogen rom the phone says "charged" a lot of time before the real charge...i think that the batterystats file isn't calibrated on your new battery, and so it says charged before...if you have a custom rom i think it's useful (if not necessary) to do a battery ricalibration (i.e charge the phone until the 100% then wipe the battery stats via recovery and then let the phone discharge until the 0%)
I don't know if this will help you, i hope!
I think
When i go back home tomorrow and pick up my extended battery, i will try this. thanks.
edit: yes i have a custom rom. it's oxygen.
i bought it awhile ago, and i feel like the stock 1650mAh gave me more battery life than this extended one.. i notice by the Screen on time i got easily about 3 hours with evry rom/kernel on 1650mAh ,3hours screen on time + still 30% left
but with the 2000mAh i get only about 2 hours screen time while 30% is left :C what is wrong with it .. i thought itd be much better than this..

Try to use BatteryCalibration. May be it help you.
i tried everything ,battery*2000mAh genuine* still only givin me barely 4hours with min Usage LOL
Try to wait a little. I bought the original 2000mah battery and it needed about a week to give me 3-4 hours of screen time
Hi!! Did you buy an original samsung battery or a chinese-looking one?? because There are several posts here on XDA and in many other sites, wich explains you that only original batteries have the right amount of ampere. For example the Gold batteries, very common on ebay, promise you 3500 ampere, but they actually have less than the stock 1650 ... So buy only sammmie's battery!! they are way better!!
@ OP: How much you paid for it? What's the model number? I have two 2000 mAh extended batteries here, both performing well.
it cost me 35$ plus shippin cost i paid 60$ for it, its genuine.(Model:EB-K1A2EBEG) i get 4hours on screen time with brightness down to 0
i didnt get any better result than that.
