PhoneLifespan

Phone reviews obsess over launch-day specs but ignore the thing that decides real cost: how long the manufacturer keeps shipping security updates. We wanted to make device longevity the headline number a buyer compares on.

• Built a database of verified end-of-support dates for 914 phones across 25 brands
• Created a 'TrueCost' metric — monthly cost based on how long a phone stays safe to use
• Added head-to-head comparisons, 'Dying Soon' alerts, and a preference-based phone finder
• Published rankings, a brand update-policy tracker, and a documented methodology

A longevity-first phone research tool that reframes the buying decision around total cost of ownership and security support — not just specs.
