New app features?

[Goldtrom]

It just says “yesterday” in the App Store. I know I’ve seen 3 charging sessions on my Lock Screen and in the status island thing. The data from my energy tracker confirms 3 charging sessions roughly 24 hours apart.

The apple App Store seems to have no idea what today and tomorrow are here in Japan. It’s already past midnight here (so the 9th) and it still says the Porsche app was updated yesterday.
An app I manually updated yesterday still says Today and one I just updated says yesterday. It’s just totally confused.

Not 100% sure yet but the new live activity tracker seems to be draining the battery. I’m on a 6 week vacation. Left the car at 50%. I have power monitoring setup a can confirm the first 4 weeks it only used about 4.7 kWh/week in single bursts once a week. Since the app update it’s been charging in 1.5kwh every 24h. I just shut off the live activity to see if it stops.

Why would the live activity tracker be draining the HV battery if the car is not charging?
It would make sense for the live activity tracker to become live once the car is charging.
If you went on holiday why leave the car plugged in?
Should not the car last for months on 50% and charge the 12v battery as needed by itself?
I am assuming the monitoring is on the EVSE?
How do you control the charging?
Do you use the Porsche API and set the EVSE to charge to 50%?
Sorry for all the questions.

Regarding the version I am on v16.25.32, looking at the versions posted each region must get its own version.

My understanding is waking the car drains the 12v which gets charged by the high voltage. So in essence the app polling the car causes a drain on both batteries. I can totally imagine the high voltage being woken is enough to cause an accelerated drain. If the pattern held iit is draining at about 2x what I was seeing without the live activity tracker.

I assume the tracker is polling instead of using notifications. That’s why it’s draining the batteries faster.

It all makes sense to me. I’m just sharing data and plausible explanations. Fact is since the update the car has been charging at an increased frequency. Is it related? I’d say probable.

my home runs an enphase solar and ev charger setup. I can tell in the app my whole house usage and what the ev is using. The graph is from home assistant which uses the enphase API to get finer granularity data than the enphase app.

I left it plugged in at the recommendation of Porsche. It costs me nothing (I have 3mwh+ annual excess generation ). Many EVs are known to have excessive drain. I saw no reason to take the risk of destroying my cars HV battery.

Also even at the original drain rate it was going to use ~30kwh. At 50% the car has ~47.5 kWh. At current rate it would use everything and unless it has working built in protection a dead battery.

It’s possible by leaving it plugged in the live tracker switched to polling instead of notifications.

won’t know the result of my experiment for another day or so. But what other plausible explanations are there ? Temps where it’s garaged have actually dropped. So I doubt it’s cooling the battery.

Does the car auto update any of its SW? Guess it could have run some update that is causing excessive drain.

 

[Goldtrom]

Garage temperatures for the last 4 weeks to confirm what I said about it being cooler.

Is it confirmed that keeping it on a charger will maintain the 12v battery? One dealer told me I had to get a trickle charger for the 12v if I let it sit for a few weeks.

I use the app, iOS home screen widgets, and check the status of the car regularly and never noticed any drain whatsoever on the 12V or HV battery from constant usage. I even have the Porsche status widget on the desktop of my Macs -- so quite frequent updates are probably occurring.

I don't think there is anything to worry about.

 

[Goldtrom]

The data is what the data is. I’m attempting to collect more. We shall see how it goes. But the fact is it increased the drain after the app update. Correlation is not causation but doesn’t mean it not the cause.

Over in Tesla world, this is well known - don't run apps and monitors etc if you want to avoid unnecessary battery drain. When you're on holiday, just trust that there'll be some battery left, don't keep waking the systems up to check. Avoid vampire drain as much as possible. If you're in your garage at home, fire up the Tesla app on your phone and look at the climate screen for example - you'll hear your Tesla wake up, click and whir. Maybe Porsche have better monitoring software, will be interesting to see more data over time, Goldtrom.

VW Group and BMW vehicles are not known for any vampire drain issues.

 

[Goldtrom]

I hope that is sarcasm. The Taycan forums are full of excessive vampire drain issues. And every electric car has vampire drain. The question is how much.

Nope, not sarcasm. None of my electric vehicles exhibit any noticeable SoC change unless things like pre-conditioning are set to run, which obviously will use HV battery. I have plenty of experience in this area.

If your Macan is seeing SoC losses while parked and no preconditioning/departure setup then there is something wrong with it.

 

[Goldtrom]

It’s obviously impossible to have zero vampire drain.

We’re talking about ~30w average before the app update and 60w after. I have a trickle charger on another ICE car and it pulls 10w pretty continuously. And cellular connections + some less efficient electronics can easily add up to 30w. I do think it’s high. I work for a company that designs these kinds of electronics. I’ll probably ask someone I know what ours uses.

Where? i had 6 Taycans, Gen 1 and 2, none had vampire drain issues, quite the opposite!
