Is XSX still downloading game updates while in energy saving mode?

No your mistaken the xbox doesnt have to b on insta on to download system updates and game updates. Insta is just for remote installs n fast boot but xsx use energy saving. Fo to system n updates and enable update while console off

XSX UK version has no 'Instant On' mode either. My 2 options for 'Sleep mode' are 'Energy saver', or 'Standby'.

I noticed my XSX was venting warm air in Standby mode 9hrs after use, so I switched to Energy saver mode. But then game downloads whilst off didn't continue to download.

Apparently, an update changed things to allow 'game updates' in Energy saver mode when off, but 'game updates' are just patches?

I have tried ES mode to DL Game Pass games, but they pause when the XSX is off. Remote DLs via the app won't work either in ES mode.

So, I've had to turn it back to standard power-greedy 'Standby' mode to DL games whilst off - although it seems very slow compared to when the XSX is fully on.

I think games only DL in ES mode for the first 1m45s, at which point you hear the XSX rev up and go silent again - and in that time my console has only DL-ed about 0.02GB, and at that rate it'd take about 1 day to DL a big game! My 'fibre broadband' is pretty poor though: The XSX in-built speed test says the DL speed is 15Mbps, at best.

Also switch the console to energy saving mode as automatic updates will eat up your download limit. In energy saving you will only download updates for games if you try to play them

Thanks for the answer. Well, my auto update always off because sudden downloading while gaming makes my connection bad. So all this time did sleep mode is useless for me and from now i will choose saving energy mode then sleep mode

Thanks a lot for clearing those things up!

Now, system and game updates can be downloaded during Energy Saver mode, further saving energy.

This is great!
