Price and Configurations
Neither phone is cheap. The Razr Ultra comes in two configurations: 512GB of storage for $1,299.99 and an unpriced model with 1TB of storage that will be released later. Both versions come with 16GB of RAM.
The Galaxy Z Flip 6 starts at $1,099.99 for 256GB of storage and jumps to $1,219.99 for 512GB. Both models have 12GB of RAM.
Motorola selected the latest Qualcomm Snapdragon 8 Elite processor for the Razr Ultra. Meanwhile, Samsung's Z Flip 6 runs a previous-generation Snapdragon 8 Gen 3 for Galaxy processor. Both chips are speedy, so performance won't be an issue.
While the Razr Ultra is $80 more expensive than the Flip 6, it offers more RAM with the same 512GB of storage and has a newer processor.

Size and Design
Both phones have a front display and flip open to reveal a large, full-size inner screen. The Razr Ultra measures 3.47 by 2.91 by 0.62 inches (HWD) closed and 6.75 by 2.91 by 0.28 inches when open. It weighs 7.02 ounces. The outer glass is covered with Corning Gorilla Glass-Ceramic, which the manufacturer says can survive repeated three-foot drops, though we have not tested this claim.
The Galaxy Z Flip 6 is slightly smaller than the Razr Ultra. It measures 3.35 by 2.83 by 0.59 inches when closed and 6.70 by 2.83 by 0.27 inches fully open. It is also lighter, at 6.60 ounces. The Flip 6 is protected by Corning Gorilla Glass Victus 2, which is less durable than Glass-Ceramic. However, the phone is equally resistant to dust and water, as it also sports an IP48 rating.
Motorola collaborated with Pantone for the colors of its devices. The Ultra comes in Cabaret (pink), Mountain Trail (wood), Rio Red, and Scarab (black Alcantara). The Z Flip 6 also comes in a handful of colors, including Blue, Mint, Silver Shadow, and Yellow. Those colors are widely available. If you want Crafted Black, Peach, or White, you must buy it directly from Samsung.

Screens
Both Razr Ultra displays are larger than those of the Z Flip 6. The Razr's 4.0-inch pOLED external screen features a resolution of 1,272 by 1,080 pixels with a refresh rate up to 165Hz. It reaches up to 3,000 nits of peak brightness, so you shouldn’t have any problems viewing it in direct sunlight. Motorola lets you access apps, widgets, and Moto AI from the external display. You can conduct a Google search or check your email without ever opening the phone.
The Ultra's inner screen is a 7.0-inch AMOLED panel with a resolution of 2,992 by 1,224 pixels and a dynamic 165Hz refresh rate. It reaches up to 4,500 nits of brightness. Again, you won’t have problems seeing your screen on a sunny day. Motorola says it reduced the visibility of the crease—it's basically invisible when the screen is on.
In contrast, the Z Flip 6 has a smaller, 3.4-inch Super AMOLED cover screen with 720 by 748 pixels and a fixed 60Hz refresh rate. You can mostly only access widgets from here, though Samsung has a few apps optimized for the smaller screen.
When open, the Z Flip 6 has a 6.7-inch Dynamic AMOLED 2X screen with a resolution of 2,640 by 1,080 pixels and a 120Hz adaptive refresh rate.
Motorola's screens are simply larger and brighter.

Cameras
Flip phones typically have passable cameras, but Motorola appears to be testing the limits. The Razr Ultra has a 50MP f/1.8 main camera with optical image stabilization. It also validates color and skin tones via software based on Pantone’s colors. The phone also has a 50MP f/2.0 combined ultra-wide and macro camera with a 122-degree field of view and a 50MP f/2.0 front-facing camera for selfies. The phone can record 8K video at 30fps and 4K video at 120fps, as well as 1080p at 60fps or 30fps.
The Z Flip 6 has a less impressive camera array. It also has a 50MP f/1.8 primary camera but only a 12MP f/2.2 ultra-wide camera and a 10MP f/2.2 selfie camera. And it can shoot 4K video only at 60fps.
If photography is important to you, you’re better off going with a regular bar-style phone. The Google Pixel 9 Pro is currently our choice for the best overall camera on an Android phone.

Batteries and Charging
The Motorola Razr Ultra has a 4,700mAh battery with a max wired charging speed of 68W. Of course, a power adapter doesn’t come in the box, so you’ll have to supply your own power brick. The phone can also wirelessly charge up to 30W and reverse-charge accessories at 5W.
The Z Flip 6 is powered by a smaller 4,000mAh battery. Its wired charging capabilities max out at 25W, while it can charge wirelessly up to 15W. It does not support reverse charging. You’ll need to provide your own power adapter since you won’t get one in the box.
We’ve yet to be able to officially test the battery on the Razr Ultra, but the Z Flip 6 managed an impressive 16 hours and 20 minutes on our battery test.

AI, Software, and Connectivity
Like the rest of the 2025 lineup, the Razr Ultra comes with Moto AI baked into the system. The phone includes a dedicated Moto AI key that allows you to access Moto AI from anywhere. The software now lets you get a summary of your notifications with Motorola’s Catch Me Up. It can also transcribe meeting notes with its Pay Attention AI feature, while Next Move suggests planning your next steps based on the information on your screen.
When the Razr Ultra is in tent mode, you can just glance at the phone to engage Moto AI—no button or wake word necessary. This feature is called Look and Talk and is exclusive to the Ultra. Perplexity, Meta, Google, and Microsoft partnered with Motorola to help create Moto AI so that you can access various AI features from these companies on the phone.
Under the Galaxy AI umbrella, Samsung's AI features are on the Z Flip 6. Notes Assist can summarize your notes, Browser Assist can summarize or translate pages in Samsung’s internet browser, and Sketch to Image lets you create an image out of a sketch that you draw on the screen.
The Motorola Razr Ultra comes with Android 15. The Samsung Galaxy Z Flip 6 launched with Android 14, but it can be upgraded to Android 15. In fact, Samsung promises seven years of OS and security patches, while Motorola has yet to announce an update policy for the 2025 Razr lineup.
As for connectivity, the Razr Ultra supports sub-6GHz 5G, including C-band. It does not support the faster mmWave connection found on T-Mobile and Verizon. Conversely, Samsung includes C-band and mmWave on its Galaxy Z Flip 6.
