Samsung Galaxy Z Fold 7 vs Xiaomi 15 Pro

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• 25W charging hasn't improved and feels outdated when competitors offer 65W or faster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

Xiaomi 15 Pro

The 6,100mAh silicon-carbon battery combined with the ultra-efficient display delivers class-leading endurance. NotebookCheck awarded a 93% battery score, and the phone consumes dramatically less power than its predecessor (4.42W vs 6.17W for display). 90W wired and 50W wireless charging round out the package.

• 6,100mAh silicon-carbon battery delivers class-leading endurance — competitors consume more than twice as much energy
• 90W wired HyperCharge and 50W wireless charging provide fast top-ups
• Display consumes just 4.42W vs the Xiaomi 14 Pro's 6.17W — a 24% improvement in power efficiency
