I just got the 8220 flip two days ago. After charging, the battery lost more than 50% of the charge in less than 12 hours!
I was told that this thing only needed to be charged ONCE A WEEK and that if it doesn't hold the charge, it needs to be sent back.... I am thinking that it's not just my flip that's defective, perhaps it's the whole product line.
Also, another rip-off - the blackberries normally come with a media card, mine didn't, so you can't download music or other media files without eating into the on-board memory. Ridiculous! I'm paying $$ every month for a fancy phone that offers nothing. Thanks Rogers.
