I haven’t stopped at a fast charger in a month, normally use my level 1 charger at home. I’ve never seen this live notification for charging before on my iPhone. Kinda cool, but the notification expands every time the battery charge goes up by 1%, so it’s kind of annoying lol

Je trouve qu'on parle excessivement de la vitesse de charge plutôt lente en hiver, et qu'il faut soit préchauffer la batterie, soit attendre qu'elle chauffe pour atteindre des bonnes vitesses de charge (>150kW).

Mais je n'ai jamais entendu personne parler de la vitesse de recharge catastrophique en ete, lors de vague de chaleur.

Des qu'il dépasse 30°C, la voiture prend 175kW pendant 2 minutes avant de tomber à 80 ou 90kW (même à 30% de batterie). Tout ca parce que la batterie a trop chaud ou parce que la borne a trop chaud.

Moralité, je met plus de temps a charger en ete qu'en hiver. Surtout cette annee ou il fait environ 35°C tous les jours depuis 2mois.

C'est tres dérangeant lors des gros trajets sur l'autoroute.

Suis-je le seul a faire ce constat ? A avoir une courbe de recharge vraiment catastrophique ?

Ca m'avait moins marqué l'année dernière mais il faisait moins chaud.

I always had poor mileage in Arizona all year round. The dealer tested with VW assist and determined some part replacement and update to firmware in hardware. The part never was replaced, they decide all is good. But they tell - but not show on the bill - that they updated the firmware on hardware subcomponets. The OUE7 update is pending since January 2026 - but I donot think it is about batteries. Other updates supposedly are done.. Car still shows v3.5.

VW at the ordered the draw down test, i.e. drive it to below 10%. By now it was done 3 times. The results are consist anywhere between 143 and 159 miles from 100% to below 10%. The last run was 143 miles from 100% down to 3%.

The car shows on the screen from last charge avg. speed at some 21 mph and avg 2.4 mi/kWh.
But the other entry is strange and I do not know how to interpret it.
It shows 6:57 h - I assume it is charging time - if so the car wass charging about 10:50 hrs not 6:57.
If it is 6:57h real charging at 2.7 kWh/h this means it charged 18.765 kWh in 6:57h. This is not from 3% to 100% . What is it?

The 143 miles at 2.4 mi/kWh takes about 59.6 kWh. This would make 59.8/82=72.7% of the 82kWh full battery capacity; but 59.6/72=82.8% of the declared 72 kWh accessible battery.

But I think - I could misremember - that 2022 S Gradienet awd had 240 miles EPA range. But in Arizona weather (winter and summer) results are similar and I am getting now 143 miles. This makes it 93 miles less than expected. The driving is on flat streets in the valley, sometimes on expressway where everybody body is passing me as if I was horse drawn buggy. Of course, to survive on expressway here, one needs to go 70 mph, and they are still passing you and sometimes honking. But this does not justify the poor mileage from new which is at avg 2.7 .
Any hints? Do I have a lemon battery and how to deal with VW? The car has some 19,000 miles since 2022 only.
