The OnePlus 13 attacks the S25 Ultra with a simple weapon: more of everything, for less. But is it that simple?
Design and display
Both play the big 2K 120 Hz card. The OnePlus is lighter (213 g), the Ultra more controlled with anti-glare Gorilla Armor. Equal quality, two personalities.
Battery and charging: OnePlus crushes

|---|---|---|
| Battery | 5000 mAh | 6000 mAh (Si-C) |
| Charging | 45 W | 100 W |
| Full charge | ~1 h | ~35 min |
The match's biggest technical gap: the silicon-carbon battery changes daily life.

Performance and software
Same 8 Elite, near-identical results. But support diverges: 7 years at Samsung versus 4 at OnePlus — the gap long-term owners notice.
Verdict
- OnePlus 13: battery, charging, price — the rational gamer's pick
- S25 Ultra: S Pen, 5x zoom, anti-glare, software longevity — the complete pick
