Our take on the Samsung Galaxy Z Flip 4 SM-F721 5G

The Galaxy Z Flip 4 is Samsung's clamshell foldable: a 6.7-inch folding screen that halves into a pocketable square. Its headline trick is Flex Mode, which props the phone open at an angle for hands-free selfies and split-screen use. It suits people who want a compact phone with a distinctive design more than maximum battery life or camera reach. Against the Flip 3 it brings a slightly larger battery, a faster chip and a less visible crease; against slab flagships it gives up telephoto zoom and endurance.

Questions and answers

Is the Galaxy Z Flip 4 worth it over the Flip 3?
Yes if battery life and speed matter to you. The Flip 4 has a larger battery, a faster chip and a tighter hinge, though the design and crease are similar.
How is battery life?
Moderate. Most owners get through a normal day, but heavy camera, gaming or hotspot use drains it well before night.
Does it have a telephoto camera?
No. It has wide and ultrawide rear cameras, so zoom is digital and softer than on phones with a dedicated telephoto lens.
Is the screen crease a problem?
It is visible at an angle and you can feel it, but most owners stop noticing it in normal use.
Is it water resistant?
Yes, it carries an IPX8 rating for water, but not for dust, so keep it away from sand and grit.
What comes in the box?
The phone, a USB-C cable and a SIM tool. No charger is included, so you need your own USB-C power adapter.
