Could your next phone also become your favourite reading device? The iPhone Duo makes a compelling case for readers who value convenience, colour and flexibility.

The Instagram reel shared by @rebekkahfinds captures the attraction: a phone that opens like a book. For commuters, travellers and anyone squeezing chapters into a busy day, that idea is appealing. But could it actually be better than a Kindle? For some reading habits, yes.

1. Your book is already in your pocket

A dedicated reader is useful only when you remember to bring it. A phone usually comes along automatically. If you already plan to buy the Duo, using it for books could mean one less device to pack, charge and keep track of.

That convenience matters on an MRT journey, during a lunch break or while waiting for an appointment. More opportunities to read may matter more than having the perfect reading setup.

2. A bigger canvas for colour content

Apple specifies a 7.6-inch folding OLED inner display with a nano-texture finish designed to reduce glare. That larger canvas could suit illustrated books, magazines and documents better than a conventional phone screen.

Compared with a monochrome Kindle Paperwhite, full colour is an obvious advantage for photographs and diagrams. Kindle Colorsoft also offers colour, however, so the choice depends on whether you prefer a phone display or a dedicated e-reader.

3. More reading apps in one place

The free Kindle app lets iPhone users read their Amazon books and sync reading progress, bookmarks and notes. Kobo’s iOS app supports its ebooks and audiobooks too, while Apple Books provides another reading option.

This flexibility makes a phone attractive if your reading spans several services. Your purchases still belong to their respective platforms; installing multiple apps does not merge their libraries.

4. Useful for reading and research

Apple describes Split View support for two apps side by side. In supported apps, that could help you consult a reference while taking notes or checking a detail online. Actual layouts will depend on each app’s Duo support.

For study or practical nonfiction, that versatility could be more useful than a device built mainly for uninterrupted reading.

Where Kindle still has the advantage

The Duo uses OLED, not E Ink. Reducing glare does not turn it into a paper-like Kindle screen. A Kindle also keeps messages and social feeds away from your book.

Amazon advertises up to 12 weeks of battery life for its new Paperwhite, subject to usage. If you mainly read novels for long stretches, a dedicated reader remains compelling—and buying a premium phone solely for ebooks is difficult to justify.

Which suits your reading life?

Choose the Duo for convenience and varied content if you already want the phone. Choose Kindle for focused reading. This is a comparison of published features, not a hands-on review: Apple lists Singapore availability from 23 October 2026.
