Sources: Apple replaced 11M iPhone batteries under the $29 replacement program in 2018, up from an average of 1-2M
Jean-Louis Gassée, on Apple's earnings warning: … I'm pretty sure Gassée's back-of-the-envelope estimate of the number of batteries replaced was way too low.
Context & Ripple Effects
A year after Apple's apology over battery management that slowed older iPhones, the scale of the make-good is now visible: sources put 2018 replacements under the $29 program at 11M units, against a historical run rate of 1-2M a year. The program was also pulled forward — Apple made the $29 price effective immediately rather than waiting for late January, while warning of constrained initial battery supplies.
Jean-Louis Gassée ties the figure to Apple's earnings warning, arguing earlier back-of-the-envelope estimates of replacement volume were far too low — meaning the program's cost to Apple, and its effect on the installed base's upgrade timing, were both underestimated.
First-order effects
- Apple absorbed roughly five to ten times its normal annual battery-replacement volume at the discounted $29 price, a direct hit captured in the earnings warning Gassée references.
- Customers with aging iPhones gained years of usable life at a fraction of standard repair pricing, with supply constraints early in the program rationing who could take advantage immediately.
Second-order effects
- Cheaper, faster battery swaps weaken one driver of annual upgrade cycles, pressuring iPhone revenue precisely when Apple is leaning harder on services and installed-base monetization.
- Repair partners and the battery supply chain had to scale output dramatically mid-cycle, shifting bargaining power toward suppliers able to ramp cell production on short notice.
Third-order effects
- If goodwill-priced repair becomes the template for defusing obsolescence backlash, hardware makers face a structural trade-off between upgrade revenue and trust repair — with transparent battery health and cheap replacements becoming table stakes rather than crisis responses.
The trend: Consumer backlash over device longevity is pushing hardware companies from opaque power management toward subsidized repair programs that cannibalize upgrade cycles to protect brand trust.
