If I decide to keep the 3588i (looks like I don't have much choice ) I sure would like to do something about it's battery usage. I go from fully charged (7 bars) to 2 bars in less than 24 hours, and that's without even using the phone (it is turned on). I'm wondering if the Nokia BLC-2 Ultra Extended Li-Ion Battery (950mAh) ($59 from Nokia but as low as $13.49 - before S&H - at Yahoo! Shopping) is an improvement over the battery that comes with the phone. Or should I just get used to charging it every day and a half?
