I am a recent Blackberry to Iphone converter and there is a few things I miss about the Blackberry but there is far more I like about the Iphone. I have been messing with settings and adjusting to all things Apple and have noticed or at least I swear I have noticed that if I leave my battery percentage display off the battery lasts longer!! I have been using it for about a week with it on and about 5 days now with it off and same usage usually about 10 emails and 200 or so text messages a day and between 30-45 mins of talk time. I start my day at 8AM and with the percentage on by 4PM I would see around 45% left now with if off I can go all the way to 6PM before the icon is near that level, maybe the icon and the percentage displays slightly differently but I think it makes sense that it would make some difference as the percentage display is going to always be reading the battery level and adjusting the display accordingly. Am I crazy or did I just find the easiest way to squeeze just a hair more life out of my phone? I also will say that although I am adjusting to the process I would love to be able to just USB the phone to the PC and send files to it like the Blackberry, Itunes is a really stupid middle step to me.
