I always try to use "energy savings on" to avoid wasting a few kWh per day while my car should be sleeping.
HOWEVER, in the 2019 software releases, startup problems have been multiplying:
1) Instrument cluster takes up to a minute to come up
2) Sometimes MCU (center) screen reboots at startup
3) Sometimes backup camera starts up black or fails to come up on first reverse
4) Often audio does not resume (when it doesn't, it will if I leave and re-enter car)
These (particularly #1, which just cropped up) have been driving me CRAZY because they are ALL REGRESSION (i.e., used to work!). So, on a whim, I went to Display settings, and turned "Energy Savings OFF. That completely cured all of these bugs. Unfortunately, that means I have to choose between buggy startup, and wasting several kWh per day.
FWIW, I have experienced the same on both my 2012 P85 and my Model 3 Performance. I posted here in S-land because problems are more severe and frequent in my S.
Anyone else getting these issues (or others) with Energy Savings on?
ASIDE: harking back to my systems engineering days... I suspect this is caused by programmers of the various sub-systems failing to coordinate and fully test how state is saved when energy savings kicks in and puts car to sleep, and restored after startup. Either saved state data is being overwritten, or "go to sleep"/"wake up" procedures are inconsistent in terms of sequence. Regardless, a thorough system test process ought to catch this.
