OnePlus 13R vs Samsung Galaxy S26 Ultra

OnePlus 13R

The OnePlus 13R adopts a squared-off design that feels premium at 8mm thin and 206g, lighter than its predecessor despite housing a larger battery.

• The squared-off design looks great and feels premium in hand, though flat edges can dig into palms during extended use
• At 8mm thin and 206g, the 13R is thinner and lighter than the 12R despite packing a larger 6,000mAh battery
• IP65 is an improvement over the 12R but falls short of IP68 submersion resistance that rivals offer at this price

Samsung Galaxy S26 Ultra

The S26 Ultra is the thinnest (7.9mm) and lightest (214g) Ultra ever, ditching the titanium frame in favor of Armor Aluminum. Rounder corners improve the hand feel significantly. Gorilla Glass Armor 2 protects the display. The design change from titanium to aluminum is divisive — some see it as a downgrade, others say it doesn't matter in real use.

• At 7.9mm thin and 214g, this is the thinnest and lightest Galaxy Ultra ever — noticeably more comfortable to hold than the S25 Ultra
• Rounder corners give the S26 Ultra a more comfortable grip — a welcome departure from the sharp-edged Ultra design language of recent years
