Battery Life: The Biggest Improvement
The iPhone 13 delivers approximately 2.5 hours more daily battery life than the iPhone 12, thanks to a physically larger battery cell and the A15 Bionic's improved power efficiency. For users who found the iPhone 12's battery life insufficient, this is the most compelling upgrade reason.Support Lifespan Considerations
- iPhone 12: Released 2020, projected support through 2026–2027. May receive its final major iOS version (iOS 19 or 20) soon.
- iPhone 13: Released 2021, projected support through 2027–2028. Gains approximately one additional year of major OS updates.
If longevity is your priority and you want the most remaining support life, consider skipping both and going directly to iPhone 15 or 16.
Verdict
The iPhone 13 is a modest but meaningful upgrade over the 12 — primarily for battery life and the doubled base storage (128GB vs 64GB). However, neither model supports Apple Intelligence. Users looking for the best long-term investment should consider the iPhone 16 or a discounted iPhone 15.
Questions this page actually answers
How much longer will the iPhone 12 be supported?

Is the iPhone 13 camera better than the iPhone 12?
Yes, moderately. The sensor-shift OIS (borrowed from the iPhone 12 Pro Max) provides better stabilization, and the larger sensor captures more light in low-light conditions.
