Best way to preheat my car

[f1eng]

Your manual precondition doesn't use the battery, or timer doesn't use shore power?

Both.
Both use shore power if plugged in, and, of course, both use the battery if it isn't.

Nice. I wish mine did that. Manual pre-conditioning will only use shore power if battery drops below the set "minimum" profile threshold. I saw it using shore power once and I got excited that maybe some software update fixed it, but tried it couple of days later, nope, preconditioning on, EVSE not delivering any power.

I wonder what the difference is. A bug in US charger software?

Don't know.
I know you are dissatisfied by your Taycan software and criticise it frequently but I have no complaints.

The chassis software, brakes, steering etc., works fine on mine and the gadget side is of little interest to me, all my other cars over the last 50 years have neither had nor needed software or updates

I find the App features, particularly the pre-heating capability, to be a nicety I hadn't expected but do appreciate though.

I guess it depends on prior experience. If you never had pre-heat, any remote starter is an improvement (I had an ICE rental car with remote preheat last week when traveling). If you had one before, a worse implementation stands out. In this case, it's the engineer in me that is bothered by my manual pre-heat not using shore power, since it's obviously possible in my car since it works when using timers. Since it works well for your car and not mine, this again points to poor software which apparently doesn't even behave consistently within the same car line.

About Porsche software, it definitely is lacking as compared to state of art automotive software today, but my wife has an eTron, and based on the Audi I can confidently tell you that it can be worse. For example, the eTron shuts off within very few minutes when the driver leaves the seat, even if you leave the keys with the passenger! You can't even leave passengers in the car when going into a store because the HVAC will shut off (to turn it back on you have to press on the brake while hitting the ON button)! It has a bunch of other idiosyncrasies, some no doubt inherited from old ICE car design decisions (such as having a separate Accessory Mode ON and Engine ON modes, with A/C inoperational in Accessory mode for example). Oh, for completeness, the eTron never uses shore power for pre-conditioning (unless charging the HV battery).

If the car is plugged in, the most optimal (at least for me) way is to set a pre-conditioning timer on the app for when you want to depart. I do this instead of just starting the pre-conditioning manually, even when setting it only minutes prior to departure. Why? Because Porsche sucks at software and apparently two different teams who don't talk to each other implemented manual preconditioning and timer based pre-conditioning. Manual pre-conditioning uses battery power (draining the battery before departure, adding to battery aging charge cycles), while the timer based one uses shore power (straight from the EVSE plugged into the car) without draining the battery. Sure, they could have just copied what Tesla has been doing for over a decade, but you know Porsche, they always prefer to learn on their own mistakes - too proud to learn from others.

Hmm not sure about aging cycles. A cycle is 0% to 100% remember.

Yes, it's a cumulative count of how much energy went in and then out. Charging 84% to 85% one hundred times counts the same as one charge 0%-100%. There are some chemistry dependent differences but generally what is being counted and charge-discharge cycles. If only actual 0%-100% were counted, as long as you never discharged your battery to 0% it would never age!
