spare batteries anyone?
Sent from my GT-I9100 using XDA App

Seeing a few on eBay now but it's unclear what the capacity is. I'm wary of them anyway as I've had Chinese sellers send me the wrong battery for recent phones (check the listing, the battery described is often different from the one in the title!). Also I've had fake capacity batteries sent out - 800mah or less packed out to full capacity size with foam-rubber!
I'm hoping someone will make an extended capacity battery as it wouldn't need to stick out the back much as the i9100 is recessed anyway. There is an external battery pack available but it's just an additional battery that clips round the phone, not a replacement. Fugly too!

Ditto. Would love to score some batteries by next week since I'm going on a trip and won't always have access to an outlet. Especially since the battery drain is horrible.
Guess we're out of luck in the States since it'll take a while if shipped from UK

Looking at eBay I see a backup battery like this:
1900mAh Back-Up Battery For Samsung Galaxy S2 II i9100
Granted it is not an actual spare battery...for approx USD$10 it may be worth it to get it for some emergency juice for the phone.

-Charge battery to 100%
-In recovery, wipe battery stats
-Lets phone die [so that it automatically turns off]
-Charge back to 100%, use as normal

Try juice defender also

I had the extended for awhile i couldn't get over the bulk of it .
Have a hero and a TP2 so i just keep 2 charged batterys at a time and switch
I found the cheap ones work just as-well as the 60 dollar ones at best buy aslong as you condition them

I only paid $13 for this battery. I haven't even seen it's full potential yet. I'm a bit worried cause now I cannot use a case for it..but gives me more reason to try going red with it. Anyway, I was switching between 3 batteries and it wore out
My back. It was convenient yet annoying. So these batteries just need some conditioning?

I got mine for 8 dollars on Amazon lasted 2 days all i would do is calibrate at 100% completely drain then repeat for the first few charge cycles.
Worked like a charm just couldn't get over the girth

Hmm I see. I can get used to it, I just cannot have it in my pocket at work anymore. And its no longer protected so it is risky but I needed a change since I'm not getting the 3D right now lol

If you want an extra extended battery PM me your address ill send it to you just doesn't have the backing any more I kinda of broke the back cover

Duct tape it together lol and that is nice but would it cost you to send it?

Battery 3500mAh

I am very sorry if there is already topic like this one.
I found on ebay a battery that was 3500mAh or 3600mAh I don't recall exactly, but they say that it is the exact size like the original and won't change the size of the phone like the 5000mAh does.
My question is did someone has it,and how is it working? How many hours did your phone last?
Thank You in advance!

Absolute nonsense. Every battery that claims vast improvements in the same form factor is a scam.
If 3500mah could fit in the space provided, Samsung would have included a 3500mah battery.

I Don't agree,there could be a lot of reasons why they didn't put one,from budget point of view to supply issues. It's not like they strive to bring you the best at any cost.

If you meant the Gold battery, then it is 3500mAh. I bought two and noticed a huge difference compared to my stock battery. The stock used to power the phone until 7pm with moderate usage, wifi and bluetooth always on. Ever since I used the Gold battery, the battery still is at approximately 40% at 11pm. The battery still is 2 days old but still, the difference is noticeable

can you guys do a nova battery tester run on those batteries?

Mine came with 2800 mAh. Since it's cheaper than stock it has worth the purchase. Don't get your hopes high with these batteries.
Your srock may be dieing if it's almost a year old. Mine got down to 1700 mAh and this explains the "huge" difference you see in your new battery.

I bought the Gold battery two months after I got my Note so it means the OEM is still at it's peak. But yeah, I really don't have high hopes for replacement batteries. They may have a higher charge but they won't last as long as OEM. Like my dslr batteries, I get more juice out of the replacement batteries but my OEM battery outlasted them. But it is still worth it for me. What good is a camera (or phone in this case) if it does not have power when you really need it? Battery life does not matter to me (atleast in my case since I could buy 4 to 5 replacement batteries for 1 OEM dlsr battery - the Gold battery however, is another case).I keep that mantra all the time and I am happy with it :laugh:

Question about battery calibration

So how do batteries get "out of calibration" (if they do)? It would seem to be an issue of the phone not recognizing when a battery is fully charged, so it would not charge completely when...well...charging... Would using the ever-popular "reboot" feature lead to that?

Lithium Ion batteries need no calibration. That was a big thing when Nickel Batteries were being used.
Some people sware by it and say it works. But I believe its a placebo effect. If your having battery issues its probably just a bad battery, that tends to happen from time to time.

I fully appreciate that battery calibration wouldn't be affecting the batteries per se...was wondering if it was really more of calibrating how the phone itself measures or tracks the charge state. I certainly appreciate your position though..since I've often thought that too. In the end....I really don't know.

Get the gs2 1850 mah batteries they fit right in stock cover and charge normally as well. I've had this phone since first release and let me tell you I have 2 batteries since release and 2 newer ones and I get way shorter life on the older batteries.

So I have never cleared my battery stats as they were talking about in that article (and the million comments with it)... I have done the fully charge and then discharge cycles....which I always had thought was a waste of time with lithium ion batteries... There was a lot of...interesting dissenting comments in that article...

Defective battery?

So I ordered a 1800mah battery for the epic. It fit and everything but literally while charging it and on browser on just data, the battery life decreases while on the charger. It also almost died at school today. On my 1500mah, I ended a 7 hour day with about 30-40%. On the 1800mah, I got down to 20 and below. If kind of makes me mad that I bought a bigger battery and out sucks. And what is a good 1800mah battery for the epic?
Sent from my SPH-D700 using xda app-developers app

The battery from the Epic 4G Touch is your best bet. And as for it dying on the charger, it's the charger, not the phone or battery. I know this because it's happened to me. Try a different charger

Yes I ordered the Samsung epic 4g touch battery. And sadly it isn't my charger because I am using the same charger on my 1500mah battery and its charging fine.
Sent from my SPH-D700 using xda app-developers app

Not always the charger.... When I'm on 4G and trying to use Google Maps even plugged in I drain my battery. If I shut GMaps down, it starts charging as per normal.
It was really frustrating when I first got the phone, as I was in the process of moving to Denver and knew where nothing was. Now, at least, I know the area well enough to just have it on at the start or end of trip.

The Anker samsung battery (search amazon for it .. ~$10 and 1800mah) has shown good results for me.

it is normal for the phone to consume more power than the charging pack can output....... you might not of had this problem because the 1500ma battery uses less energy than a 1800mah battery(hence the extra life..) if you charge with a USB 1A charger it should charge the new battery better. also, turn of 3g and watch your battery charge about 2times faster than with it on.

And yes it does perform better. I have 2 1800 mAh Anker batteries and there amazing I got a deal for 2x 1800mAh batteries and the charger from Anker. For 20$ on amazon don't listen to reviews they said the charger is bad but mine has performed well for several months and still is. I. Had gotten 4 days before on CM9 with minimal use and on regular basis I get 12 to 18 Hrs with 3 Hrs of screen on time

This is the one I ordered -- getting about 20 hrs of battery life vs. 12 hrs on my stock (2 year old) battery. Non-OEM batteries are typically a hit or miss, but amazon's return policy is dead simple and free, so IMO worth a shot.
