Frequently Asked Questions
Why keep phone longer?
CO2: 60-70 kg per phone manufactured. Cost: $1000+ per upgrade × 4-yr cycle = $250/yr just on phones. Most phones still work fine 4-5 yr — battery + screen are usually only worn parts.
When to upgrade for sure?
Below 60% battery health AFTER replacement. No security updates (5-7 yr typical). Hardware fail (camera, mic, speaker). Software requirements outpacing (banking apps drop support).
Battery replacement worth it?
iPhone: $89-99 official, restores 90% performance. Android: $50-80 via 3rd party. Often best ROI in tech: $80 saves $800 new phone + 2-year delay.
