Benchmarks reveal the dark secret of the Samsung Galaxy Flip 4

Preliminary benchmarks on the Samsung Galaxy Z Flip 4 and Z Fold 4 show two phones with powerful processors and the ability to run games at up to 120 frames per second – but the Z Flip 4 has a key flaw.

In my early testing (which has yet to be verified by Samsung), the Galaxy Z Flip 4 throttles more than any other phone I’ve seen under heavy loads.

Good news: Lightning-fast processors

Both the Samsung Galaxy Z Flip 4 and Z Fold 4 use Qualcomm’s Snapdragon 8+ Gen 1 processors in all regions of the world, Samsung says. The Snapdragon 8+ Gen 1 is said to be 10% faster than the Snapdragon 8 Gen 1 in the Galaxy S22 and 30% more power efficient. (We see the energy efficiency in our battery test.)

According to CPU-Z utility, the 8+ Gen 1 has four 2GHz cores, three 2.75GHz cores and one main 3.2GHz core. The Asus ROG Phone 6 Pro and OnePlus 10T also run the 8+ Gen 1.

On Geekbench you can see the boost where the Snapdragon 8+ Gen 1 phones perform better than the Galaxy S22+. In the PCMark application test, the improvement isn’t that big, but it’s still there. So yes, these phones are fast and powerful.

Bad news: go full throttle

Our CPU throttling test benchmark reveals the Flip 4’s Achilles’ heel: the phone quickly throttles its performance.

The Flip 4 and Fold 4 started the 15-minute test with roughly the same performance. But after a few minutes, the flip pulled far back while the fold didn’t throttle nearly as much. (It’s worth noting that the OnePlus 10T throttled less in performance mode than any Samsung I’ve tested.)

This was also confirmed in a short gaming session. I played five minutes of Alto’s Odyssey, a light casual game, followed by five minutes of Genshin Impact, a high-performance game. Genshin Impact was set to medium graphics and 60 fps. I used WeTest PerfDog performance software to test frame rate and temperature.

Both phones played Alto’s Odyssey at around 120 fps. But the Flip warmed up more than the Fold during this session: While the Flip climbed to 104 degrees Fahrenheit, the Fold stayed slightly cooler at 98.6 degrees.

Under the stress of using Genshin, the Flip couldn’t break 40 fps and levels off at 38-39 fps after six minutes, while the Fold hovers between 40-52 fps in terms of frame rates.

Meanwhile, PerfDog says the OnePlus 10T averaged 57 fps and frequently hit the 60 fps gaming limit – something the Flip couldn’t do at all and the Fold only briefly. I plan to test this again before my final review.

Important to note: It’s not a gaming phone

These results just underscore something we already knew about the Galaxy Z Flip 4: it’s not a hardcore gaming phone. The odd aspect ratio when unfolded and held in landscape mode is part of that. But maximizing the performance under high load is not the focus here either. More specifically, the folding design presents Samsung with clear challenges in managing thermals.

The design of the Galaxy Z Flip 4 is perfect for photos, videos, social media and almost all games. It won’t overheat when you’re watching videos, surfing the web, posting on Instagram, or playing Pokemon Go. In addition, both the Z Flip and the Z Fold 4 have excellent cell phone reception.

However, the Galaxy Z Fold 4 performs better under heavy load. That could mean better performance when playing a game like Genshin Impact or PUBG Mobile, or recalculating a spreadsheet during a video call.

I’m in the middle of my Galaxy Z Fold 4 and Flip 4 reviews right now and will have more details as I continue, so check back soon.
