Can I use my phone instead of a cycling GPS computer?

You can, but a dedicated GPS computer offers much better battery life, screen visibility in sunlight, water resistance, and sensor connectivity. Phone screens wash out in direct sunlight, battery drain is rapid with continuous GPS use, and a crash can destroy an expensive phone. A cycling computer is a worthwhile investment for regular riders.

How important is battery life for cycling computers?

Very important, especially for endurance riders. A unit that dies mid-ride is useless. The Garmin Edge 540 offers 26 hours, enough for even the longest gran fondo. For most riders, 15-20 hours covers a full weekend of riding without charging. GPS accuracy mode and screen brightness are the biggest battery drains.
