Like most hungry entrepreneurs, Jason Saltzman is constantly on-the-go, managing a growing team as well as a thriving business, reports Entrepreneur. As the founder and CEO of New York City-based shared workspace Alley, he needs a smartphone to keep up with him. So do you.

In this video, Saltzman outlines his six must-have features for any great smartphone:

1. Long-lasting battery/fast charging

2. Size

3. Water resistance/durability

4. An always-updating platform (like Android)

5. Expandable memory

6. A great camera

“Things change, schedules change, you need to completely stay on top of things,” Saltzman says. “Having the phone with the right technology will help you do that and help you run your day."
