Tesla Software updates - Australia

[doggy1]

My range in km has not changed since the day I took delivery 4 years ago

That's good.

My car (before the recent glitch where it stopped waking over LTE) used to wake up every 24hrs for about 15 to 25mins. Loss per day was under 1%. On the other thread where we were looking at the fail to wake issue, a S-plaid owner said that his car wakes up every 5 hours! Given that mine used nothing measurable over more than 4 days, with no awakenings, it seems the main drain would be in the awakenings. I wonder if yours is waking up more times per day than it used to? If your car was awake 2.4hrs per day, that would be over 1kwhr which might be 1.5% or more....maybe.....

@paulp I'm halfway through a 3 week overseas trip and have the car sitting in garage, sentry not on, not plugged in, teslafi polling set to normal. It loses about 1.5% per day of sitting there. Wife on standby to go plug it in if needed...

One area where there seems to have been constant improvement over the past year of releases is Vampire Drain. Now admittedly my LTE seems to have been off the air for a while (documented in the "Cannot wake from App" thread). However, the car went to sleep over 4 days ago with 77% battery and I just woke it up and it is still at 77%! So, worst case, 0.25% loss per day. This is very acceptable indeed. That is with the car unlocked in the garage and in deep sleep.

I've only had the car for a month or so and I've just got back from a 2 week trip away, battery dropped 2% from 80% to 78%, which i thought was pretty good. 2022 M3LR (so old battery type).

I also seem too suffer from the car not waking for the app, and to be a bit random though.

I just went to my app and it said “car last seen an hour ago” - which is a bit of an issue given I last looked at the app about 12 hours ago. It seems to be communicating when it should be sleeping?

Maybe it is waking up every 5hrs as reported by the now 2 guys with the S-Plaids. It would certainly explain increased drain.

just opened my app. I'm on iOS, app was not running, i.e. I kill it every time I close it by swiping up so it doesn't do background refreshes. On opening the app it immediately says "last seen 3 days ago", refreshes about a second later and states "last seen 6 hours ago".

So the "last seen" text clearly is when the Tesla servers last talked to the car, not the app.

Another interesting observation: The app refreshes quicker from here (Europe) than from home in Australia. Lends further evidence to my suspicion that the Tesla in-car SIMs are in fact US based home network SIMs requiring a round trip from Aus to the US for all comms. And thus is quicker from Europe (100ms ping time to US vs. 250ms to US from Aus)

And slightly off topic - on my iPhone 12 with 5G Swisscom I get 1.1Gbps downstream, 150Mbps upstream. We have a ways to go in good ol oz....

I also noticed of lately app not waking up car as quickly as before
Can sit there for 5 min sometimes and nothing. Is this to help with the drain by reducing the car wake up?
It’s happened since the last update 28.2

Something happened in the last 6 months to cause a substantial increase. I’m going to do a test against my other same age (and similar distance driven) S and see if its the car or a generic issue

If it's a car issue, it could be the 12V lead-acid battery on the way out. The car has to wake up and charge it more often if it's failing.

I had an interesting experience of this with my Renault Zoe. After 4yrs, the loss of SOC went from 1% per month (car locked) to 1% per day. This was during Covid and because of infrequent driving, the energy consumption went from a 125Whr/km to around 300. The 12V auxiliary battery tested okay for internal resistance, capacity (down about 30%) and CCA. But I replaced it (actually with an AGM rather than conventional starter battery) and hey presto- everything went back to the way it was before. Less than 1% loss per month. I still have the old battery and I use it for things like spot welding. Basically, it takes quite a bit of power to keep charged. So I can imagine the same type of issue potentially happening with a Tesla 12V battery which I understand is a fairly basic starter battery from the ICE world. I do a lot of work with batteries and I have not seen a lead acid battery behave like my Zoe battery has.

I find the "last seen" text to be total nonsense much of the time. E.g. it says last seen eight hours ago, despite me having driven it for an hour and a half during that time. What's the point?

Agreed, I have had it show last seen 3 days ago, even though I have been driving it every day. It does seem like a total random to me most of the time.

But maybe the message refers to the last time your App was used to wake the car?
That's always been my assumption about the meaning, but I could be wrong....

Interesting comment, given the other identical age S had a low voltage battery failure last week on the last day of warranty

 

[Maximillan]

I've got 2022.28.2, and whilst TACC has improved, Autopilot is super panicky about any cars changing into an adjacent lane. Twice I've had it sound the alarms and slam on the brakes, one of those a hire car gently changing into the lane next to me. I never had this issue pre-Tesla Vision.

I won't use it on three lane freeways until hopefully they release a more developed version.

Does anyone remember if the charging stats shown on the screen (when charging) have always been gross?

I thought they used to show what was going into the battery (KW, km/hour, SOC%) but maybe I am mis-remembering. Plus they have changed the font to be more readable so maybe I did not notice before?

I was at a JOLT which means my gross was 23kW but the nett was only 13 to the battery (as confirmed by ScanMyTesla) but the onscreen display said 23kW and 100km/hr). I was sure it used to show the nett! But my brain is aging........

 

[moa999]

On screen definitely used to show Net - which is why people were complaining Jolt was so slow
(I got 19/20 in my SR+ - single motor and no heat pump)

 

[doggy1]

On screen definitely used to show Net

Right then! Another undocumented change.........

Is it a change to what's displayed, or what the car is doing?

 

[doggy1]

No change to what the car is doing. Just what is displayed (which is now misleading because gross and not what is going into the battery). Probably only an issue on JOLTs
