iPhone Duo Faces Benchmark Challenges from Android Foldables

With the launch of the iPhone Duo, Apple is jumping into a category that Samsung has dominated for nearly seven years. A fresh report from Ookla based on real-world Speedtest data looks at how Android foldables perform compared to standard flat phones.

The findings present a challenge for Apple as it tries to match Android benchmarks. Ookla’s numbers show that foldable devices made up only about 1.4% of all Speedtest samples worldwide through early September.

Samsung dominates this market segment. The South Korean tech giant holds 76.2% of the total foldable market share, claiming eight out of the top ten most popular foldable models in Ookla’s sample data. The Galaxy Z Fold7 alone accounted for nearly a quarter of all foldable test samples.

When Ookla compared book-style foldables to standard flagship slab phones with similar internals, the results were eye-opening:

• Speed Improvements: Newer generations of book-style foldables regularly show better download and upload speeds than their traditional counterparts.
• Thermal Issues: Bending phones run noticeably hotter. The Galaxy Z Fold8 Ultra ran 0.34°C warmer than its traditional control phone, the S26 Ultra, during performance tests.
• Signal Quality: Signal efficiency (measured via SINR) tends to drop slightly in foldable designs compared to standard flat designs due to packed internal antennas.

Thin designs often mean skipping vapor chamber cooling systems or sacrificing battery ventilation. That thermal bottleneck affects how long a processor can sustain top speeds without throttling down.

Where Apple might win isn’t just raw network output or thermal endurance, it is software integration. Android phone makers still struggle with third-party app scaling on odd aspect ratios, leading to awkward letterboxing or stretched interfaces. If iOS delivers seamless app transitions and dynamic layout scaling out of the box, Apple could set a new standard for daily usability.

Apple faces a steep climb to break Samsung’s hardware stranglehold, but its tight control over software might be the secret weapon that makes the iPhone Duo stand out.
