OnePlus Open vs Samsung Galaxy S23 Ultra

OnePlus Open

4,805mAh dual battery + 67W SuperVOOC wired + 50W wireless — class-leading charging for a foldable. Real-world endurance ~5-6h SOT typical, comparable to Z Fold 5.

• 4,805mAh dual battery + SD 8 Gen 2 efficiency — comparable endurance to Z Fold 5 (4,400mAh).
• 67W SuperVOOC wired charging — full in ~42 minutes. Dramatically faster than Z Fold 5's 25W (~1h-1.5h to full).
• 50W wireless charging — vs Z Fold 5's 15W. The fastest wireless charging in any foldable of 2023.
• Real-world SOT ~5-6 hours typical — fully a day for most users, comparable to Z Fold 5.

Samsung Galaxy S23 Ultra

5,000mAh paired with the efficient 8 Gen 2 for Galaxy delivered the era's best Android battery life — 6-7 hours of screen-on time, still close to 5 hours of mixed heavy use after 2 years. The catch is charging speed: 45W wired (and a special cable is needed to hit it) when rivals offer 80W+.

• 5,000mAh battery + the efficient 8 Gen 2 for Galaxy gives 6-7 hours of screen-on time at full brightness in WQHD with no power-save modes.
• Two-year battery test still delivered ~4h44m of mixed heavy SOT (PUBG, Genshin, 4K video, Spotify) — strong longevity even after 2 years.
• Pure-runtime lab test hit 11h5m vs 8h13m on the S22 Ultra — a major efficiency leap from the Snapdragon chip alone.
• 45W wired charging: 40% in 15 min, 72% in 30 min, 91% in 45 min, full in ~1h3m — but only with a separate 5A cable and 45W brick.
• The included box cable doesn't trigger Super Fast Charging 2.0 — Samsung sells the 5A cable and 45W brick separately, a recurring complaint.
• 15W wireless charging works as advertised: 20% in 20 min, 50% in 50 min, full in 1h58m.
• Versus OnePlus 11's 80W charging (~25 min full): the S23 Ultra's 45W feels noticeably slow — the era's clearest charging gap.
