If you have one yourself, how much more time do you get on that battery?

[WibbleJanuary]

Can you explain what you mean and for what model please

All aftermarket batteries will work if you buy the right one...

I have the S2 with the Mugen 1650 - lasts me over a whole day, and fits in the OEM door. I hear Seidio came out with a 1700 that fits the OEM door as well. It would help if you would give your model as some are different mah, sizes, etc...

My experience with a Seidio extended for my old 8330 was just OK - it did not last very long - about a year - but that may just be the nature of the beast after recharging it hundreds of times. Mugen so far would be my recommendation.

And yes - of course - they really work! Just note that if the battery door has to be bigger, that most if not all cases will NOT fit the phone.

Yes, a lot of the aftermarkey batteries work well. I have experience with the Seidio extended batteries-they work very well.

Look at SEIDIO, choose the biggest capacity for your models
