Our verdict
A refined clamshell with flagship power and a long update runway, held back only by its tiny cover screen.
Pros
- 4 OS upgrades and 5 years of security, with support into 2027
- Snapdragon 8+ Gen 1 and IPX8 water resistance
- Slightly bigger 3700mAh battery and faster 25W charging than the Flip3
Cons
- Cramped 1.9-inch cover screen feels dated next to the Flip5
- Battery life is still only average for a flagship
