Worldwide Smartphone Growth Expected to Slow to 10.4% in 2015, Down From 27.5% Growth in 2014, According to IDC
According to a new mobile phone forecast from the International Data Corporation (IDC) Worldwide Quarterly Mobile Phone Tracker, smartphone shipments are expected to grow 10.4% in 2015 to 1.44 billion units.
Context & Ripple Effects
IDC's August 2015 forecast marks the inflection point of the smartphone boom: after years of hypergrowth, the Worldwide Quarterly Mobile Phone Tracker projects shipments growing just 10.4% to 1.44 billion units in 2015, less than half the 27.5% rate of 2014. By December the same tracker confirmed the slowdown as the first single-digit growth year on record for the worldwide smartphone market.
The deceleration proved structural rather than a one-year dip: IDC's follow-up forecast cut 2016 growth further to 3.1%, with Android reaching 84% of shipments at a $218 average selling price, and by late 2018 quarterly shipments were actually shrinking, down 6% YoY in Q3 2018 as Samsung fell 13.4% while Huawei grew 32.9%.
First-order effects
- Vendors planning 2015 production against IDC's 1.44 billion-unit forecast face a market adding far fewer incremental units than 2014's 27.5% pace, shifting competition from winning first-time buyers to capturing each other's installed bases.
Second-order effects
- With growth concentrated in lower-price tiers, the mix shifts toward cheaper Android devices — the pattern IDC later quantified at a $218 ASP and 84% Android share — pressuring premium vendors on price while component suppliers see volumes tied to a slower-expanding base.
Third-order effects
- A maturing market turns shipments into a replacement-cycle business rather than an adoption curve, which is why later prints swing with upgrade timing instead of climbing steadily — IDC's 2024 forecast of 6.2% growth to 1.24 billion units sits below the 2014 total-growth regime even nine years on.
The trend: Worldwide smartphone shipments have transitioned from an adoption-driven growth engine to a replacement-cycle market, with IDC's annual growth estimates decaying steadily from 27.5% in 2014 toward low single digits.
