Now that the Kindle DX 2 is out and the Kindle 2 has been updated to 2.5 it’s time for another Page Turn Speed comparison. Note that this is much less comprehensive than the prior one (details listed below).
This post has page turn speed times and comparisons. There is also a comparison video if you want to make your own measurements at the Kindle DX 2 Video Page (should be live soon) – It’s under the Kindle Page Turn Speed Comparison Video heading at the end of the post.
Kindle vs Kindle DX 2 vs Kindle DX 1 Page Turn Comparison
Here’s what we get when we compare page turn speeds with a similar number of words per page (not font size but number of words).
Kindle DX 2 Page Turn Speed
We used the 4th Font Size in Kindle DX 2 and the book was Dominant Species by Michael C. Marks.
1st run: 10 page turns in 8.7 seconds. 2nd run: 50 page turns going forwards in 41.4 seconds.
3rd run: 10 page turns backwards in 14.4 seconds. 4th run: 10 page turns going backwards in 14.6 seconds.
Which averages out to Kindle DX 2 doing forward page turns in .83 to .87 seconds and backwards page turns in 1.44 to 1.46 seconds.
Kindle DX Page Turn Speed (on Kindle 2.5.3 upgrade)
Font Size 4 in Dominant Species.
1st run: 20 page turns in 20.9 seconds. 2nd run: 50 page turns in 42.7 seconds (This was a bit of a surprise). 3rd run: 20 page turns in 17 seconds.
4th run: 20 backwards page turns in 24.2 seconds. 5th run: 30 backwards page turns in 39 seconds.
Which translates to .85 seconds to 1.04 seconds per forward page turn and 1.21 to 1.3 seconds per backwards page turn.
Kindle 2 Page Turn Speed (on Kindle 2.5.3 upgrade)
For the Kindle 2 we used Size 2 font in the Dominant Species book.
1st run: 30 page turns in 19.3 seconds. 2nd run: 50 page turns in 37.3 seconds.
3rd run: 10 backwards page turns in 11.9 seconds. 4th run: 20 backwards page turns in 21.1 seconds.
Which averages out to .64 to .75 seconds per page turn going forwards and 1.15 to 1.19 seconds per page turn going backwards.
Strangely, with both Kindle DX 2 and Kindle 2 the backwards page turns become slower around the 4th or 5th page turn. With the Kindle DX 1 this didn’t really happen though the 7th page turn every time is slower.
Results – Kindle 2 is better than Kindle DX 2 which is better than Kindle DX 1
Amazon have managed to not only improve the screen contrast of the Kindle DX 2 significantly they have also managed to improve the page turn speed for forward page turning by a slight amount. Backward page turns are slower than on the Kindle DX 1 although that should hardly be a concern.
How do Kindle Page Turn Speeds compare with Nook and Sony Reader?
Quite a while back we had compared the page turn speeds of various eReaders and had come up with these results –
… results we get –
- Sony Reader Touch Edition – 0.82 seconds per page turn. First Run: 72 pages in 1 minute. Second Run: 74 pages in 1 minute. Finishing Page: The way Dexter Predo knew. Second Run – Mr. Predo knew something.
- Kindle 2 International – 0.89 seconds per page turn. First run: 64 page turns in 1 minute. Second Run: 71 page turns in 1 minute. Finishing Page – She heads over to the Bar. Second Run – My Head to Mr. Predo.
- Nook 1.3 – Exactly 1.5 seconds per page turn. First run: 40 page turns in 1 minute. Second run: 40 page turns in 1 minute. Finishing Page – Zombies eat brains. It’s their raison d’etre.
- Kindle DX International – 1.2 seconds per page turn. First Run: 50 page turns in 1 minute. Second Run: 50 page turns in 1 minute. Finishing Page – Philip’s Connection to the Coalition.
- Kindle US 2.3.3 – 0.76 seconds per page turn. First Run: 83 pages in 1 minute. Second Run: 75 pages in 1 minute. Finishing Page: Second Run: The problem with Philip is.
The Kindle 2 US came in first, the Sony Reader Touch Edition came in a close second, and the Kindle 2 International was a close third. Every other eReader took more than 1 second per page turn.
It’s really interesting to see that the Kindle 2.5 upgrade (or perhaps one of the other Kindle upgrades) has cut down the page turn speed to just .64 to .75 seconds per page turn. This is quite an improvement.
How does the latest Nook firmware upgrade do?
This is what we get for the Nook with a somewhat comparable font setting –
Run 1: 20 page turns in 21.5 seconds. Run 2: 10 page turns in 10.7 seconds. Run 3: 20 page turns in 20.2 seconds.
Run 4: 10 backwards page turns in 13.7 seconds. Run 5: 10 backwards page turns in 12.1 seconds. Run 6: 20 backwards page turns in 24.3 seconds.
Which translates to 1.01 to 1.07 seconds per forward page turn and 1.21 to 1.37 seconds per backwards page turn. Nook has improved from its abysmal 1.5 seconds per page turn speed – However, it is still behind the Kindle by a fair margin and it’s also behind the new Kindle DX 2.
