Well played :wink: Do you have Cortana pinned to the start screen and do you have Battery Saver turned on? After a couple weeks I started getting the rapid battery drain (40% in less than an hour) usually accompanied by the start screen hanging or stuck on "resuming" for upwards of a minute. I did a hard reset and was fine for a few days but it happened again so I reverted to 8 last weekend. In other posts this week I've seen several people say unpinning Cortana and turning off Battery Saver help a lot. I didn't try either before reverting and I'm curious.
