Got a few chinese batteries...for backup if need be.
Noticed the 3.7 vs 3.8 V.
I know nothing about this and assume they wouldnt send out product not suited for the device...but wanted to ask anyway.
Any concerns?
Thanks
I've read about a Swedish guy trying some cheap and "bigger" Chinese batteries. Even though it claimed to be capable of 6500mAh is was not better than the original 3100mAh. Same discharge speed or worse.
They're the same size. Just wondering about using 3.7 V batteries when ours are 3.8.
The voltage needs to be the same as ours. Don't get anything else.

sorry for popping in ur thread. but i think its good to share/ask here ..
i have a galaxy s3 clone .. on the battery it says 3.7v 2100mah and 10.8 WH obviously the WH rating is false .. but i looked at the battery compartment on the device and it says 3.8 volt .
so what figure to believe ?
since i have the battery and multimeter so before going for replacement how should i determine which voltage battery do i need ?
i am sure that the 3.7 volts batteries are of one chemistry and the 3.8volts are of other chemistry .. so mixing is obviously dangrous..
If you originaly have a 3.8v battery DO NOT replace with a 3.7v.
I have a GN II and my original battery is 3100 Mah and 3.8 volts Samsung. I'm a battery freak and try to make my battery last as long as i can using undervolting, JD, etc. So i decided to purchase a Chinese battery for my phone which was 4200 Mah. I did not realize it was 3.7v as it does not say it on the battery but looking into it further it does say it in the description when i purchased it on ebay, and i obviously overlooked it.
I removed my stock battery and installed the new replacement. It soft bricked my phone immediately and was stuck in a boot loop and i could not get it to come on. Thank God i was able to boot into recovery. I had to reset, reload my rom, and restore everything again. What a hassle.
So idecided to try it again as i really wanted to test the performance of this new battery. This time it worked and booted OK. I fully charged it three full cycles, and started testing. Long story short it discharged faster than the stock battery, and when i put a load on it the battery discharged very quickly. Total waste of time using these batteries. Don't do it.

HI,
I have the same s3 clone, now looking for the suitable battery. I tried with the original galaxy s3 battery but it doesn't work. Have you figured it out which battery does work in this clone? Thanks in advance!

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:

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.
Okay so, my last phone was a Droid X2 and I got a 3500 mah extended battery for it. It was on Android 2.3.5 and Android's battery meter did not correctly read the battery's percentage.
When it got to 1% battery it would simply stay there for a while before it died.
I am wondering if this problem is fixed with the Galaxy Nexus or ICS in general?
I purchased a Seidio 3800mah battery and I'm curious to know if I can rely on it's battery readings.
Thanks in advanced!

I have the official Samsung Extended Battery (2100mAh) and it reads it perfectly. Charges all the way to 100% and then dies at 0% (doesn't hang at 1%).

Thanks for the quick response
I see you said you have the official battery and I'm wondering if there's anybody with a non official battery (if that even makes a difference).
Also I'm wondering about high mah batteries such as the 3800 mah from Seidio or another from Mugen Power.
Thanks
The percentage comes from the chip in the battery, not ICS. So any official battery would output the correct SoC which the driver can read. A cheap battery may or may not depending if that manufacturer setup the chip correctly.
Android 2.3.5 was identical. If it was a 3500 seido they typically give correct charge. If it was a cheaper one then thats why your droidx didnt display properly.
Has to do with the fuel gauge chip, not the OS. Galaxy nexus uses max10740. Nexus one used ds2784. Droidx was totally different too. All depends on that chip.

Yes it was a cheap off-brand battery and that probably explains why it wasn't showing correct percentages.
Thank you!
Hey guys I just saw a 3500mAh battery for SGS2 on ebay. Is it safe to use such battery? I mean it won't harm the phone, will it? :O
Probably won't harm the phone, no.
I bought a 3500mAh obscurely branded Chinese battery in mid-December. Tried it out for almost two weeks, a bunch of charge/discharge cycles & estimated its real capacity was around 1900mAh. It also used to heat up a lot on recharge (mid-high 40's Celsius, which isn't normal when the phone isn't being used whilst charging).
I took it back, got a refund & bought an original Samsung 2000mAh battery. Hasn't missed a beat, is obviously close to its advertised capacity given I get around 20% more use out of a charge than I do with a 1600mAh battery.
Obviously your mileage may vary if you buy one of these (you might have a better experience than I did), just thought I'd let you know about my experience.

Well i heard that their batteries exploded in their phones......so be careful.....better pay for a better one instead of having a chance to ruin your expensive phone.

I have one of those I got from DealExtreme and it is great. It lasts 2x longer than the original Samsung battery.
I take care not to swap them often, because I am afraid that this action might damage the original cover, eventually breaking it.
Battery Life
I am still using the 1650 mAh battery (stock) for my S2.
I am really facing some battery issues. Its charging almost all day !
Yes I am using 3G all day and WiFi HotSpot too. But use wifi at home. Thats when I get good battery life. Any better way to conserve some battery ?
Any tips might help
Thanks
Got mine a few days ago from eBay and its been fine so far. It last more than 2x the regular battery. Phone does not heat up or anything strange..

well i an getting with the original battery 24H of usage.
with the 3500mah i am getting 60H of usage... so my 3500 is truly 3500mah!
the language is hebrew.
i use congnition rom 1.51 and siyah kernel.
So, where can I see a trustful review on batteries for SGS2? What is the most extended one?
It's really frustrating that my current stock battery is only enough for 2 hd video view (4-5 hours).
Also, the higher the mAh value the more battery lifetime is, right?
I would really want to buy 3500 mAh, but it costs so little.
And the official Samsung variant that offers the longest lifetime of a battery for SGS2 is this one, maybe Mugen 3500 mAh is the best choice out there?

What is the model name of the battery? Is it being overheated in comparison to stock one?
why should it overheat?
it is lithium ... same same
Yes, it's special lithium from China extracted under full moon and blessed by a thousand virgins
Really now, if it was possible to manufacture a battery having more than double the capacity of the stock battery while taking up the same volume, don't you think the megacorporate Samsung would buy that technology immediately in order to use it themselves ? "Too cheap to be true" is valid even here; most knock-off batteries either are fake ("9999 mAH SUPER EXTRA" sticker over the original rating), or will degrade quickly in time leaving you with a dud.
Since there are already fake electronic components...
... why not fake and cheap batteries too, certainly seems to be a high demand for them.
a. it is not the same volume! in is twice as much as the original.
b. the i9100 has a circuit that allows a slow stable charge rate so i dont think it will damage the battery.
As well as being made of inferior materials, not being subjected to the same QC, not having the fuel gauge chip present in original Samsung batteries, you pretty much get what you pay for.
My advice would be to avoid non-original batteries altogether, and given a 2000mAh original battery will cost around the same as one of these 3000mAh+ batteries with all their problems & poor life, it's a no brainer.
Stick with Samsung batteries.
fuel gauge chip?
i would like to see that chip in an any cellphone battery please.
If you're not aware of/don't know about the fuel gauge chip in original SGS2 batteries, you've probably been living under a rock since the phone was released

well i think that you misunderstood the meaning fuel gauge.
there is no chip in the battery that is in charge of the fuel gauge.
furthermore there is no use of recalibrating the battery in out i9100 model.
all you gave me is a link you Google...
please... show me that chip! i would like to learn something new about lithium batteries..
Plz can you Possible link topic of the battery

Hi.
My name is Andre.
I have an xperia play that I've been using as a pocket emulator for years.
I have the NexPlay Rom installed, as well the recommended LuPuS CM9 Kernel and .58 Enhanced firmware.
Recently I bought one of these 4500 mAh battery and back cover from ebay.
The original charge it came with lasted a good while so I really believe this is not a fake battery.
But I can't get the phone to recognize the new battery capacity and charge it. The phone seems to only charge it up to the original 1500 mAh.
I've added the following line to build.prop (the line wasn't present) through the BuildProp Editor app:
ro.semc.batt.capacity=4500
But even after clearing the cache, davik cache and resetting the battery stats, I see no changes.
Can anyone help? I'd really appreciate it.
sorry i cant help, but a 4500mah battery sound nice, when i had the xplay i had a 2450 mah and worked fine, the only problem is it decayed its capacity very very quickly

Thanks anyway.
Since my original post I've done more reading, searching and testing.
Turns out there is nothing functionally wrong with the phone, other than it still thinking the battery is 1500 mah for battery duration calculations.
The charge percentage is correct, and the phone is charging the battery until it reaches a voltage of 4.2, which means it's full.
It's the battery itself that is only taking in about 2800 mah. The seller said he would send me another one.
