In any case, the write doesn't need to be fast since no one is looking. Also, they probably have figured out how to minimize the amount of RAM that needs to be saved. As a guess, they could close any open document before save and reopen it as part of waking up.
Probably posted while the synapses weren’t firing up properly.

Besides, that hypothesis was made back when I only had descriptions of the Oasis to go by. After I got the PW4 and had actual experience with deep sleep and NAND performance, I highly doubt it works like hibernate on PCs. The PW4 had way more battery drain during deep sleep on, wifi on than with deep sleep off, wifi off.

SKIP_UPDATE_CHECK has mostly solved my battery woes when leaving wifi on but honestly, I just don’t notice any difference with deep sleep (apart from waking up taking longer).
