Samsung unveiled two premium foldable smartphones on August 10. Along with the Galaxy Z Fold 4, the firm also unveiled the Samsung Galaxy Z Flip 4. Although the new Flip has a bigger battery, both devices are powered by the same low-power Snapdragon 8 Gen 1 SoC. The Galaxy Z Flip 4 has a little larger battery than its predecessor, though. The Galaxy Flip 4 has a 3700mAh battery, compared to the 3300mAh battery that comes with the Galaxy Z Flip 3. Which of these smartphones so genuinely offers a longer battery life?
In comparison to the Samsung Galaxy Flip 3, the Samsung Galaxy Z Flip 4 appears to have a 12% increase. Users’ biggest complaints about the Samsung Galaxy Z Flip 3 are its short battery life and sluggish charging speed. The new Flip 4 uses Samsung’s current flagship 25W fast charging technology, while the Samsung Galaxy Flip 3 can only support 15W charging.
Despite the nearly identical form sizes of the two smartphones, Samsung packed a bigger battery into the Flip 4—400 mAh more than the 3300mAh battery in the Samsung Galaxy Z Flip 3. But can the Samsung Galaxy Flip 4’s additional 400mAh battery help with its most pressing battery life issue? Let’s go right to the outcomes.
