E-reader vs phone? If you read a few times a week for 15 minutes, your phone is plenty. If you read for more than half an hour most days, often in the evening or outdoors, an e-ink e-reader is more comfortable and far less distracting. We sell neither phones nor e-readers, so below we compare the two without nudging you to buy anything.

Side-by-side comparison

Phone E-ink e-reader
Screen Backlit, colour, sharp Paper-like, readable even in full sun
In the evening Bright, so dim it and use dark mode The screen is not backlit; some models have an adjustable warm light
Battery Reading shares it with everything else on the phone For the Kindle Paperwhite, Amazon says “weeks”
Distractions Notifications, social media, messages Practically none
Formats and stores Any app from any store Depends on the maker, so check before you buy
Cost Already in your pocket A separate purchase
Always with you Yes Only if you bring it

When your phone is enough

A phone is a good choice when you read in snatches. Ten minutes on the bus, a quarter of an hour in a waiting room, a few pages over lunch. There is no extra device to remember, and the book is wherever you are.

It also works well if you:

  • read briefly and irregularly, and are still finding out whether ebooks suit you,
  • use lots of sources: the library, free classics, different stores. You can install any app on a phone,
  • do not want to spend money on a device you might not use.

There are plenty of free, legal books to test phone reading with. We gathered them in free ebooks, legally.

When an e-reader is worth buying

A simple rule we use ourselves: if you read ebooks for more than three or four hours a week, an e-reader usually pays off. That is our rule of thumb, not a research finding. At that volume, comfort over long sessions starts to matter.

An e-ink screen works differently from a phone screen. According to the company behind the technology, E Ink, it offers paper-like readability in all lighting and uses very little power, because only the parts of the screen that change need updating. Hence the long battery life: for the Kindle Paperwhite, Amazon mentions “weeks” of battery, a glare-free display and an adjustable warm light.

An e-reader earns its keep when you:

  • read for long stretches, an hour or more at a time,
  • read outdoors: on the beach, in the park, on the balcony,
  • get distracted easily and your phone beats the book after a few pages.

Before buying, check which stores and formats a given model supports. This differs between makers.

Reading in the evening

Be careful with popular claims here. The most cited study is the experiment by Chang and colleagues from 2015. Twelve young, healthy adults spent five evenings reading before bed on a light-emitting device and five reading a printed book in dim light. After reading on the screen, they took about 10 minutes longer on average to fall asleep, produced less melatonin and were less alert the next morning.

It was a small lab study, and the device was set to full brightness. It was not about phones in general or about e-ink readers. It does not prove that reading on your phone at night “ruins sleep”. The practical takeaway is modest: in the evening, choose paper or an e-reader without a strong backlight, and if you read on your phone, dim the screen and use dark mode. There is more on evening routines in reading before bed.

Distractions

This is the biggest difference between the two. An e-reader will not show you a work message or a social media alert. On a phone, each of those is one tap away from your book.

If you stick with your phone, turn on a Focus mode while you read and allow only your reading app. Exact settings for iPhone and Android are in how to focus while reading.

You can use both

Plenty of people read on both: the e-reader at home, the phone on the go. Add the odd paperback from the library and it gets easy to lose track of how much you actually read in a week.

One place for all your progress helps, whatever the device. In a notebook or an app you simply log the page you stopped on, and for short phone sessions you can count minutes instead. What to count is covered in page counter or reading timer, and how to choose an app in our guide to the reading tracker app. In Talemi you log the page and, optionally, the minutes, whether you read on paper, an e-reader or a phone.

FAQ

Is reading on a phone bad for your eyes? We have not found good data that shows it, and we do not give medical advice. A larger font, lower brightness and breaks make reading more comfortable. If your eyes hurt, see an eye doctor.

Is a Kindle worth it if I read only a little? Probably not. Start with your phone. If after a few weeks you are reading several hours a week, an e-reader makes sense.

Does an e-ink reader light up? The e-ink screen itself is not backlit like a phone screen. Some models add a built-in light. The Kindle Paperwhite, for example, has an adjustable warm light.
