I just wanted to post here and share my awesome experience with this product..I originally purchased it fully knowing that I may only be receiving around 40 minutes longer time on this battery and that was perfectly fine, considering an extra 40 minutes is still better than nothing!
As it turns out, this battery has not only gotten me through an entire day of texting/e-mail/voice calls for two consecutive days in a row, it has ALSO lasted from the minute I got up until the minute I went to bed without needing a charge (sitting at 30-40%)! I can't believe the change, and it completely defies what I figured would be a minimal improvement..it's a very noticeable improvement! (with the OEM batt I was having to charge before I even got done with work).
More battery life is always welcome, but I've actually been able to increase my screen brightness and I'm still noticing fantastic real-world gains with this battery..I HIGHLY recommend anyone who's on the fence about this product to go out and buy it...and Seido, if you're listening, I'd buy an even larger capacity battery (OEM sized, of course) in the future if you came out with one! I'd love to be able to have my Mogul last 24-36 hours..mmmm..I can dream, can't I?
