An upgrade cycle that keeps getting longer

Phones have become good enough that people keep them longer. Each launch still sells well; what has changed is how long the gap between purchases has become, and every extra month is revenue arriving later.

Good enough is a problem

When a new model offers a clear leap, people upgrade on schedule. When the improvements are incremental, they stretch. Trade-in programmes, carrier deals and financing all exist to shorten that gap, and all of them cost margin.

Services revenue cushions this, because it grows with the installed base rather than with unit sales. It does not make hardware cycles irrelevant.

What I'm watching

• Replacement cycle length, from carrier and survey data
• Promotional intensity around launches
• The mix of new versus refurbished devices in the installed base

Where I stand

Short, on a hardware cycle that keeps stretching while the valuation assumes it will not. The installed base is superb; the pace at which it refreshes is the soft spot.

What would change my mind

A launch that pulls the cycle shorter without heavy promotion. That would say there is still a feature people will upgrade for, and the stretching is not permanent.
