One fast foldable, one not so much
Motorola is fond of saying the Razr Ultra is the fastest flip phone in the world, which is technically true. It has the Snapdragon 8 Elite chip with 16GB of RAM, but we expect to see the Elite in Samsung’s 2025 foldables later this year. For now, though, the Razr Ultra stands alone. The $700 Razr runs a Mediatek Dimensity 7400X, which is a distinctly midrange processor with just 8GB of RAM.

In daily use, neither phone feels slow. Side by side, you can see the Razr is slower to open apps and unlock, and the scrolling exhibits occasional jank. However, it’s not what we’d call a slow phone. It’s fine for general smartphone tasks like messaging, browsing, and watching videos. You may have trouble with gaming, though. Simple games run well enough, but heavy 3D titles like Diablo Immortal are rough with the Dimensity 7400X.
The Razr Ultra is one of the fastest Android phones we’ve tested, thanks to the Snapdragon chip. You can play complex games and multitask to your heart’s content without fear of lag. It does run a little behind the Galaxy S25 series in benchmarks, but it thankfully doesn’t get as toasty as Samsung’s phones.
We never expect groundbreaking battery life from foldables. The hinge takes up space, which limits battery capacity. That said, Motorola did fairly well cramming a 4,700 mAh battery in the Razr Ultra and a 4,500 mAh cell in the Razr.
Based on our testing, both of these phones should last you all day. The large external displays can help by giving you just enough information that you don’t have to use the larger, more power-hungry foldable OLED. If you’re playing games or using the main display exclusively, you may find the Razrs just barely make it to bedtime. However, no matter what you do, these are not multi-day phones. The base model Razr will probably eke out a few more hours, even with its smaller battery, due to the lower-power MediaTek processor. The Snapdragon 8 Elite in the Razr Ultra really eats into the battery when you take advantage of its power.
