THE SMARTER CONNECTION What matters for digital business people
Battery life A day's use (7am to 9pm) is the goal. If you're a heavy user, few will get you there. A battery that comes close to (or exceeds) 3,000mAh in size is what you want.
Ecosystem and apps Accessories are not just about music speakers. Many business users look for decent covers, cases, car-compatibility. The iPhone is out in front here.
Screen Although there is an upper limit, bigger screens generally make better business phones. You can simply do more on a a 5.5-inch Galaxy Note than a 3.5-inch iPhone 4S.
Power Phones need to be well-powered to switch from app to app and function to function. Ideally your device should have a quadcore processor (chip) and 2GB of Ram or more.
4G This hasn't kicked in as a key feature yet, but it soon will. 4G allows you to connect (and tether) much faster than 3G. That opens up possibilities for conferencing and streaming.
