As I write this, my 9900 is on it's 4th or 5th charge cycle. Battery life is getting better each cycle and although not as good as my 9780 is, will get much closer after a few more cycles. I'm using 50% screen brightness (screen dimming off), 10-second screen timeout, no GPS, WiFi and Bluetooth always off unless connected, all not-in-use apps shut down and no social feeds running other than BBM; same setup as on my 9780.

With heavy phone, e-mail and BBM usage...I still manage to get though a day with 40-50% battery charge left before I plug it in. I'm on a BES as well. The 1st two charge cycles were really bad - leaving the phone almost dead by day's end...but it's getting much better on each cycle. No it may never be a 9780 in terms of battery life....but it will be better than I had originally thought. I have 2 batteries and am purchasing a dual charger. This is the best BB I've ever used and battery is better than any Android/Windows device or iPhone, by far.
