My experience is that the cheap e-bay batteries just makes the phone unstable. The 2450mAh gold battery works fine. However, here is an x-ray of the three different batteries. Looks like there is a little difference in the circuits. Even though it doesn't say much, I think it's interesting, but then again I'm a bit of a nerd....

Since the Gold battery got more Mah it would last longer, right?

Does it really last much longer? How much?

The gold batteries are just labeled as having a larger capacity but in general they have less than samsung batteries. Im having here some of them around and would say they are about the half of what they are labeled to be. So not really a good choice exept you get them really cheap (5 each) like I did.

AFAIK Samsung batteries are "bumb" ones- there's only overcharge protection circuit (even for high-end models) and NFC antenna for "N" model.
Some older models (like i5700) had also resistor to distinguish original batteries from knock-offs (if resistor was missing or had incorrect value bootloader didn't charge the battery at all).
I'd say there's not much to investigate

Do other type of larger batterys like the gold one have overcharge protection? if i bought a unoffical battery whats the % chance of it blowing up?
