Battery Tesla or OEM Audi

Can confirm, worked at a battery store for a few years throughout college. Audis for some reason always lasted much longer than any other car brand.

My S4 battery is going on 6 years and it pops off like a brand new battery in Minnesota weather.

It's a Tesla thing.

Tesla doesn't keep a buffer zone at the top end of the battery. 100% means 100% in a Tesla. Tesla advises to only use 100% when you need the extra range.

My tesla model y recommendation is 90%. I know lfp batteries are recommended to do 100% at least weekly. We do 90% but drive the car about 100 miles every work day so it doesn't even sit at 90% for very long, maybe 3-4 hours.

I have a ‘21 (Dec 2020) M3 LR AWD w/19”. I’ve put 52K miles on it so far. Generally speaking, I’ve seen very little degradation.

I bought a used 2019 LR in 2020 and my estimated range is 302 miles with 48k miles.

My 2019 M3 with 50K miles says 288 miles today (310 original) but it has been far lower at times (255 miles) and bounces around.

All Teslas lose about 10% of their range in their first year. And then it levels off considerably after that.

How practical is a Tesla for a person with a 30-mile commute (each way)? Between my commute and running around, I probably spend $80 per week on gas.

battery life is astonishingly unpredictable. I drove 20 miles, but lost ~35 miles of range. Not driving crazy, either. Everything else is decent, but can't help but feel like it's a time bomb.
