400 vs Phone (3a)
It depends
Too close to call outright
These two are within 1 point overall — it genuinely depends on price on the day. The 400 edges both longevity and performance, so prefer it when prices are close.
Value Score: 400 76 · Phone (3a) 75 — 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 Phone (3a) has the stronger camera system (3 real rear lenses vs 2).
5,300mAh vs 5,000mAh — the 400 lasts longer between charges.
The 400 is supported until May 2031 — 3 months longer than the Phone (3a).
