QUESTION Efficiency drop after 2.5 update

[MRU]

Installed the 2.5 update about 10 days back and I’m noticing that the battery efficiency has dropped significantly. My lifetime average (9000 miles and counting) is 3.41. Now the last couple of Since Last Charge readings are in the 2.60-2.70 range! I’m driving the same as before, no change in my driving habits. It is a bit colder in PNW but still mostly in the mid 40s. Anyway I have driven in the last 2 winters here but the numbers always showed 3.25+, never in the 2s. Has anyone else encountered this situation? This works out to a full battery driving range of about 300, waaay short of the promised 512.

Mine dropped from 3.6/3.8 to 2.9/3.2’s recently. Same driving same routes little low on temp not that effect the range(from 90’s to 75’s)

Surprisingly my efficiency has actually slightly increased since 2.5 update. My "lifetime" has been right around 3.1 mi/kwh. However today I drove up to Concord and back (~125 miles) in the light rain with the HA set at indicated 75 mph (actually 73) and my efficiency hit 3.3 mi/kwh. Go figure.

I have the same experience. My efficiency has dropped by almost 1/3 since the new update and same driving conditions from 3.9s to 2.9/3.2 khw

It’s just the weather guys. Not the update

Have you guys checked your tire pressures? My efficiency was down this week and my tires were at 40 psi instead of the recommended 42. Reinflated them and back to near normal again, with the slight decrease likely being due to the cooler temps here.

My efficiency has been better recently, which I attribute to ideal weather in the Phoenix area. Lifetime average 3.3/3.4, recently getting 3.7/3.8.

My efficiency INCREASED after the 2.5 update. I was normally 2.9 -3.0 but now I’m seeing 3.4 -3.6.

Mine has also been down into the mid to high 2s since 2.5. It's been cooler out, so I chalk much of it up to that. However, even in colder temps, I was hoping to see 3.0 at least

This. Every winter we start seeing posts about efficiency dropping. It's perfectly natural and expected in colder, wetter times.

That’s not my experience. I have driven my AGT through the last 2 winters here and never seen a sub-3 reading before. I haven’t suddenly changed my driving behavior this winter either. Tire pressure is 48-49 so thats not the issue. Think I’ll take it up with CS at the next service.

What would they do?

No idea. But what else can I do
