Do you want me to do this?

Oh no, don't bother yourself with it, but thank you. I only use epubs on my kobos, but when I was getting the slowness on my H2O I did convert to Kepub, but it made no difference in page turn quickness for me. Only reverting to the older firmware worked for me. But the difference now is shocking.

That was the magic version for me so thank you again for posting the exact number. I feel like I have a new reader now. My H2O is now just as fast as my Libra 2.

With these old e-readers, battery life is the most annoying concern.
A query of Google AI, to the question, "Does age affect the speed of an e-ink reader?", indicates that old technology could be the cause. There could also be an internal timer that is set when the reader senses that the screen cannot be cleared for a new page to be rendered. Is there ghosting on the display?

My page turn speed was about the same as yours on my H2O (at firmware 4.38) before downgrading the firmware. If the page turn lag bothers you, you could try downgrading to the above 4.34.20097 version. (Check which H2O you have to be sure you grab the right version) All I can say is when I downgraded the firmware on my H2O it made a huge difference in speed not just of page turns, but with everything. Everything I touch on screen is much more responsive and quicker. My page turns are now instantaneous, the same as on my Libra 2. So in my case, and for Cavy above, (and for others I have read about on reddit) the downgrade made a big difference. So for me age has not affected my Kobo H2O, it seems the newer firmware versions are what slowed it down. Good luck if you give it a try. It's very simple to do and well worth it imo.
