I had the WPD8 battery re-programming recall preformed yesterday. Specifically, it re-programmed the high voltage battery. It took 2 1/2 hours and I’m not aware of any other specifics concerning the recall. One pleasant item noted on the repair order was my battery health. My ‘20 P4 with 16k miles still had a 98% battery health. The miles might be on the low end, but 6 years and only a 2% battery health loss, is a major win in my book.

When I bought my 2018 Panamera E-Hybrid in 2018 Porsche said it was covered to provide at least 80% of it’s original expected range for eight years. Back then, articles on the car promised 31 miles (Car & Driver Jan, 2017), 30 miles (Motortrend Jan, 2017), or 50 kilometers (Wheels.ca Aug, 2018).
I realize these estimates are somehow based on a Porsche algorithm that tries to estimate the car’s load weight, change in terrain elevation, exterior temperatures and probably other factors.
I found that last summer, when the outside temperature was around 21C/70F, the car estimated a range of 44km/27Mi when first turned on, but I was usually lucky to get 30Km/19Mi
Today with the outside temperature at 8C/46F, the car estimated at the start, 32Km/20Mi but I got something like 20Km/13Mi
As my car is car is getting very close to its eight year anniversary (April 26, 2026) I am interested if anyone has actually had their car evaluated for range and, if so, what was the experience like?

For clarity - the 12v battery is not the high-voltage battery.
The 12v is manages auxiliary, safety systems and some communications with the HV battery, but it is not HV battery. If your 12v is lithium-ion, it's designed for a 10+ year life, and it's a $2-3000 battery; if your 12v is AGM, it's a more standard "car battery", 4-5 year life span (average), $3-500 to replace. Which battery you got depended in the year, the model, your options, and availability. Most hybrid cars have the lithium-ion battery.
"Battery health" reports from Porsche don't measure HV battery health but rather your 12v battery health.
HV battery health is per a HV Health Certificate. I've never had one, not sure how to get one or what it takes. But I don't believe they just "do it for free" or upon request.
I've owned 2 hyrids - one I got with 7k miles, one I got with 55k miles. Both 2018. Each would max charge to an indicated 21-22 mile range in optimal conditions during my entire ownership; but for each that netted out to 10-12 miles actual.
My current car just had all 8 HV modules replaced (story here - "Hybrid battery fault adventure...") and the HV battery performance is markedly improved - max charge range up 23miles (not a big difference) BUT they're much, much closer to actual miles, and it has more power in EV mode than it used to, being able to climb grades longer and faster w/out the ICE kicking in.
The HV battery performance does degrade over time, that's inherent. But, that's also ok as long as they keep functioning together as they should in that state. It's when all the modules don't work together, or one goes too far out of spec, that the problems arise.

More specifically:
First part of the post was to multiple posts as it seemed people were potentially confusing 12v battery health reports (and software updates) with HV battery health insights. Not the same thing.
The HV part was about yours, i.e., performance degrades. If you want insight, you'd need an HV Health Certificate. Not standard. Never come across anybody talking about one. You'd have to specifically request it and go from there.
Likely don't hear about such certifications b/c they're of little value to a current owner - as long as the battery is working and not throwing codes then it's functioning as designed - nobody's going to replace it simply because it's not hitting an "optimal" data point. Engines don't get replaced due to inherent performance degradation over time and use. Neither to HV batteries.
I mean, end of the day, if you want just "want to know" you could try to find out, but Porsche isn't replacing these batteries (or their modules) on their dime unless it's within a warranty period and the battery is presenting discernible issues impeding functionality (not optimality).

971 traction battery expectations and actual performance
Owned a 2018 4EHST with about 40,000 miles when I bought it in 2022 and drove it 8000 miles and so liked it I bought a new, personally spec'd 2023 4EHST.
The 2018 regularly gave 20 or even 25 miles around town in E mode. I live in N Florida and it was less in January and February, but that mileage is in my daily commute sweet spot. I think the 2018 version 1 has a 14 kWhr usable capacity.
The 2023 has an 18 kWhr usable capacity. The stated capacity after charging and now 17000 miles, 63% electric, ranges from 28-34 miles and the actual from 24-28 after charging overnight in a garage that never goes below 50 F. Clearly there is a sweet spot for charging/use but I am not sure what it is.
Anybody got an hard data.
In any case, having owned 7 Porsches, I am very happy with this one and love the way that it can turn from well-mannered into a hooligan by putting the foot down hard!

Received car today. They replaced everything HV battery related, except the case. All new cells, wiring, controller. I was 2 months from expiration of the HV battery warranty. Total repair cost, zero.

HV Warranty Problems
I love the hybrid models, but will keep trading for a still under warranty year model going forward.

Porsche Hawaii, Jacksonville, and North America gave me the run around during the HV warranty period. Including three times "we can't recreate the battery cooling code you're reporting", a claim the hybrid cooling pump was frozen but not covered as part of the hybrid system (it wasn't frozen), and no help from Porsche N America when the HV finally gave out a few months after the warranty expired ($22,000). It was only after the new battery experienced the same cooling code that the dealer found the HV cooling evaporator was bad ($1900).
I love the hybrid models, but will keep trading for a still under warranty year model going forward.

What symptoms was your car presenting that was eventually determined to be the cooling evaporator?
I ask because my CEL is on again, along with a notable lack of EV power and some jerky low speed shifts when in EV mode.
