Oppo Find X9 Pro vs Samsung Galaxy Z Fold 7

Oppo Find X9 Pro

Record-breaking battery life. The 7,500mAh silicon-carbon battery delivered the highest endurance score GSMArena has ever recorded — nearly 22 hours of active use. PhoneArena called it the best battery life tested in two years. This is easily a 2-day phone that can approach 3 days with conservative use. 80W wired and 50W wireless charging complete the package.

• GSMArena Active Use Score of 21:57 hours — the highest ever recorded by the publication
• PhoneArena: best battery life tested in the past two years — 25.5 hours web browsing, easily a 2-3 day phone
• 80W wired charging fills 0-100% in approximately 45 minutes with 50W wireless charging support

Samsung Galaxy Z Fold 7

Battery life remains the Z Fold 7's most persistent weakness. The 4,400mAh cell has to power two large displays, and while the Snapdragon 8 Elite's efficiency helps, heavy use of the inner display still drains the battery quickly.

• Using primarily the cover display, the Fold 7 can last a full day — but heavy inner screen use cuts that short
• 4,400mAh is an improvement over the Fold 6, but still feels insufficient for a $2,000 device
• 25W charging hasn't improved and feels outdated when competitors offer 65W or faster
• Wireless charging and reverse wireless charging are included, as expected at this price point
