■ The catch — co-equal billing, always
You can't buy the tested one on Amazon. The 43h / 20h41m records belong to the DA14260 (Core Ultra 7 355), sold only direct from Dell — every Amazon XPS 14 listing is the older DA14250 (Core Ultra 7 255H), a different machine none of these battery numbers describe.
Dealbreaker? Runner-up №1 (ThinkPad T14s) ships on Amazon with all-day battery ↓

Same name, wrong machine
The Dell XPS 14's 20h41m / 43h records belong to the DA14260 (Core Ultra 7 355). Amazon stocks only the DA14250 (Core Ultra 7 255H) — a different laptop none of those numbers describe. Match the model code, not the name.
One number lies
The same Dell XPS 14 measured 20h41m (Tom's Guide), 24h59m (CNET) and 43h (Hardware Canucks, VRR) — lab rigs disagree by 15-50% on one machine. Match the test workload to yours; no single headline figure is the truth.
ARM's hidden tax
Snapdragon laptops post the biggest battery numbers, but x86-only apps run through Microsoft Prism emulation at a 15-25% performance penalty. Test critical line-of-business software on ARM before you commit a fleet.
