チェックすべきポイント
Camera quality matters more than megapixels — look at sensor size, aperture, and night mode performance.
128GB storage is the minimum in 2026; 256GB recommended if you shoot lots of photos and video.
Check the software support period — 6–7 years of updates dramatically extends useful lifespan.
Battery mAh alone is misleading — software optimisation matters as much as raw capacity.

iPhone vs Android — which should I choose?
iPhones offer the best software consistency and longest support. Android gives more hardware choice, customisation, and often better value at mid-range prices.
How often should I upgrade my phone?
Every 3–4 years is reasonable for most people. Flagship phones in 2026 are fast enough that annual upgrades offer minimal real-world benefit.
