Blackjack Extended Battery

I recently purchased an extended battery for my Cingular (now at&t) Blackjack. With my standard battery was to get about a full day of usage(from around 7A - 11P) on one charge. I normally had 1 bar left on the battery icon. Every now and again I had to stick it on the charger around 6P. My normal usage is mostly data, I send and receive ~ 25-100 emails per day, read RSS feeds about every 45 mins with NewsBreak (I don't have it set-up to auto refresh, I do it manually) and view a few webpages. I only use my phone for voice ~ 20-40 mins per day.

After reading some good reviews on the extended battery I placed an order with Samsung. They shipped it the next day. As with the standard batteries it takes about 1 week of the drain/charge cycle to see the full potential of the battery. While I have not been brave enough to not charge it over nite I normally have 2 bars of battery left when I stick it on the charger at nite.

The extended battery also makes the phone feel a little more substantial than the standard battery. It does feel bigger/heavier in my pocket but it's not bad at all and I like the way it feels in my hand.
