Agni 3 vs K13 5G
It depends
Too close to call outright
These two are within 2 points overall, so it depends on you: keep phones for years → K13 5G (supported until Apr 2029); want maximum speed → Agni 3 (MediaTek Dimensity 7300X (4nm)).
Value Score: Agni 3 72 · K13 5G 74 — 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 Agni 3 has the stronger camera system (3 real rear lenses vs 1).
7,000mAh vs 5,000mAh — the K13 5G lasts longer between charges.
The K13 5G is supported until Apr 2029 — 7 months longer than the Agni 3.
Pound for pound, these two are equally good deals.
