Just over ten days after the launch of the foldable Galaxy Z Flip 4, teardown expert PKBreviews reveals what’s behind its specs before customers receive their order.
The Galaxy Z Flip 4 is not much different from the Z Flip 3. They have the same 6.7-inch AMOLED primary display and 1.9-inch Super AMOLED secondary display, have high-end Qualcomm Snapdragon processors, similar cameras, and come with 8GB of RAM. .
The Z Flip 4 hits stores and mailboxes on August 26th, so the teardown is useful for those who are still undecided about whether or not to invest in foldable devices.
The notable difference between the Flip 3 and Flip 4 is the battery capacity. The Flip 3 has a 3,300 mAh battery, while the Flip 4 has a 3,700 mAh battery, which should give owners of the new device an extra three hours of battery life.
But PKBreviews’ disassembly suggests that reaching the batteries, which are glued into place and hidden under several flexible ropes, brackets and boards in each half of the folding structure, is not easy. There is a smaller 1700mAh battery on one side and a 2630mAh battery on the other.
Relatively low maintainability.
The Galaxy Z Flip 4 is probably not for those who like to fix their own hardware. PKBreviews gave it an overall maintainability score of four out of ten. It scored 0.5 out of 2 for screen replacement and 0.5 out of 2 for ease of battery replacement.
PKBreviews did not dare to remove the screen from the Z Flip 4 because the chances of damage to the device are high.
Another notable feature: The Galaxy Z Flip 4 is waterproof but not dustproof. The Z Flip 3 completely failed the iFixit dust test.
