The number one flaw I currently see in the Bold 9930 is battery life. And unfortunately, that's a very significant flaw, especially for business users who depend on their handhelds to last them at least a full day before needing another charge. In my tests, the Bold 9930 got about 6 hours and 20 minutes of talk time, while in an area with full 3G coverage.

Well, that's not bad at all, you say? You're right, six hours of talk time is average or better for a modern 3G smartphone.

The problem is that the Bold 9930 barely makes it through my work day with moderate to heavy use. For example, if I unplug my fully-charged Bold 9930 at 8 AM, and then use it regularly throughout the day, sending and receiving e-mail and BlackBerry Messenger (BBM) messages, occasionally checking Twitter and placing a phone call or two, the Bold will be dead by the time I get home around 5 PM.

Again, in comparison to some other devices I use--ahem, Motorola Atrix--this battery life isn't bad at all. However, RIM spoiled me with the BlackBerry Bold 9780, and to a lesser extent, the Torch 9800, which can easily last 10 hours or more of heavy use on a single charge. For me, it's frustrating to have to get used to a device that offers significantly less battery life, especially since BlackBerrys are typically known to have great battery life.

RIM could certainly release software updates in the future that improve overall 9930 battery life, but the fact that actual "JM-1" battery pack in the Bold 9930 has a lower capacity (1230mAh) than the Bold 9780 (1550mAh) and the Torch 9800/9810 (1270) is probably the best explanation for this decrease in battery life.
