Well, my screen is already cracked, so I could see how long the corner that does work lasts running this. Anyone have a looping GIF I could try?

Would be interesting)

Ive tryed this app and it seems like the driver doesnt turn off in this fastrefreshmode, even if the page doesnt change visually, its still sizzling if you hear closer.

That's normal for the E-Ink display. Try turning off NoRefresh and letting the "Slide to Unlock" screen display for a while, you'll hear it then too.

No, only while the four arrows are refreshing. Usually when the screen doesnt change, you hear nothing.

That's what I meant. When the screen changes, NoRefresh or not, it makes the noise.

Huh. That's kind of cool, actually, however bad it might be.

Thanks, that was a useful observation! I'd noticed when testing with a relatively CPU heavy application that power consumption didn't seem to vary between a static or moving image in A2 mode (iirc 12.5 hours of battery life with moving image, 13.5 hours with static image), but took this to mean that power consumption from the eink screen was negligable at the slow (~1fps) update rates I was using and that the CPU usage was responsible.

Sounds like that's not the case, and it's useful to know the only real test required is to listen to the screen

I use this NoRefresh App very happily!

Combining with the multitouch mod, reading PDF is amazing.

This is exactly wt i expect for an e-ink PDF reader

Neither i really know what is the power consumption of the screen itself and what is the consumption of driver (+ potentially cpu usage for drivercontrolling) compared to screen power consumption. Nor i know if that noise necessary means screen is refreshing.
Besides its not in every application the case. To be hoonest it was only one application, that reproducible show that behavior(i dindt tested it much)
My coolreader and opera mini doesnt have it. So its on your own to test it in your application))
