All the phones included in our Best foldable phone list have been thoroughly tested and used by one of our expert reviewers.  We don’t review phones of any type based purely on benchmark scores or marketing hype. We use them as our everyday device for the review period, which is usually at least five days but can often be a lot more if the device requires it. Whenever you read a phone review published on Trusted Reviews, you should be confident that the reviewer has put their personal SIM card into the phone, synced across their most-used apps and logged into all their typical accounts. We do this so you’ll feel confident in our review and trust our verdict. Our review process includes a mixture of real-world tests, along with more than 15 measured tests and industry-standard benchmarks. We believe this gives the most rounded view of a device.
