400 Pro vs 15T Pro
It depends
Too close to call outright
These two are within 1 point overall, so it depends on you: keep phones for years → 400 Pro (supported until May 2031); want maximum speed → 15T Pro (MediaTek Dimensity 9400+).
Value Score: 400 Pro 70 · 15T Pro 69 — methodology
The lifespan decider
When specs are close, support length decides it — this is what each phone costs per month of safe use.
Category by category
Both displays are effectively the same class.
Performance is a wash — same chip tier.
The 400 Pro has the stronger camera system — same lens count, higher-grade sensors.
5,500mAh vs 5,300mAh — the 15T Pro lasts longer between charges.
The 400 Pro is supported until May 2031 — 8 months longer than the 15T Pro.
Pound for pound, these two are equally good deals.
