One of the biggest complaints about Samsung’s foldable smartphones has been their battery life and charging speeds. Samsung has addressed those issues with the Galaxy Z Flip 4 and the Galaxy Z Fold 4. The Galaxy Z Flip 4 comes with a bigger battery (3,700mAh) and faster charging (25W), while both devices benefit from the more power-efficient Snapdragon 8+ Gen 1 processor.
A new video from YouTuber TechDroider shows putting the Galaxy Z Flip 4 and the Galaxy Z Fold 4 (4,400mAh) through a battery life test. These phones are pitted against Samsung’s own Galaxy S22 Ultra (5,000mAh), the Apple iPhone 13 Pro Max (4,352mAh), the OnePlus 10 Pro (5,000mAh), and the Xiaomi 12S Ultra (4,860mAh). Surprisingly, the Galaxy Z Flip 4 and the Galaxy Z Fold 4 outdo the Galaxy S22 Ultra despite a lower battery capacity.
Galaxy Z Flip 4, Galaxy Z Fold 4 battery life results
In a test that takes the phones through gaming, web browsing, and social media apps, the Galaxy S22 Ultra was the first phone to die. It lasted 8 hours and 56 minutes on a single charge, and its temperature was around 50.4°C. The Galaxy Z Flip 4 lasted 9 hours and 4 minutes, and its temperature was 42°C. The Galaxy Z Fold 4 managed to last 9 hours and 18 minutes on a single charge. Its temperature was around 39.7°C.
Both new foldable phones managed to last longer and run cooler than the Galaxy S22 Ultra. This shows how power-efficient the new Snapdragon 8+ Gen 1 chipset is compared to the Snapdragon 8 Gen 1. TSMC’s 4nm process seems much better than Samsung Foundry’s 4nm process.
The OnePlus 10 Pro lasted just one minute longer than the Galaxy Z Fold 4 but ran hotter (45°C). The Xiaomi 12S Ultra, which uses the Snapdragon 8+ Gen 1 processor, lasted 9 hours and 38 minutes on a single charge but was almost as hot (44.1°C) as the OnePlus 10 Pro. The iPhone 13 Pro Max had the best battery life with a runtime of 10 hours and 35 minutes but ran slightly hotter (40.5°C) than the Galaxy Z Fold 4.
