I've had the extended now for about a week and do enjoy the fact that it never is close to running out of juice. In fact I don't think I've had it go below 50%. For kicks today I threw the standard back on (to see if it needed charging, it still ended up with 50% on it after a week of sitting), and I found that it felt much lighter and slimmer. Has anyone decided to go back to the standard after using the extended? There is a fairly substantial weight difference especially since it's weighted more towards the bottom of the phone. I find it makes no difference when holding the phone in landscape and playing games but is very noticeable when holding it normally.
