Really enjoying my car but hate charging to recommended 85%

[JRNJTAYCAN]

So I have had my RWD pretty loaded up since March 2022. I just hit 4K miles so I do not drive it that much but I have to say that I hate one thing! The recommended 85% charging. I have only charged the car to 100% four times since owning it and that was only because I was going long distance. I love the range you get at 100% (on long trips 285-300 miles)but normally I charge to the recommended 85% (207-225 miles) which I hate. Every car I have ever owned (ICE) the dealer does not tell you not to fill your tank! So why do we spend over 100K for a car that we should not fill or charge to 100%? If I leased the car I would be charging to 100% but since I am a long term owner I follow the recommended charge.
I am just venting so please don't be a hater with any response.

What are your thoughts?

If you bought a ICE car and the manufacturer recommended hi-test gas but you used regular gas, you would see an effect in performance and possibility of damage to the engine.

It's your car and you can do what you want. Personally, I think the 85% suggestion is based on old information on battery life and with the 8% battery headroom on the Taycan there might not be any effect from charging to 100% on a regular basis. But that's just my feeling and I don't think Porsche, since the Taycan platform has been around for only two years, has enough long term information on battery life to know if the 85% suggestion will extend the battery life.

As for me, I charge once a week so it doesn't really matter whether I charge to 85% or 100%. It doesn't affect my driving experience.

It's funny I have an Audi and BMW that does recommend hi-test but I only use regular in them and they are fine.
I know it's my car and I can do what I want but I am hoping to get 10 years out of this car before selling it and I am hoping the battery stays strong!
Thanks for your POV as I do not disagree with your thoughts.

If I regularly drove over 200 miles in a single day it would bother me. I don’t, so it’s not even something I think about.

Afaik, you can charge it to 100%, just don’t leave it on a parking fully loaded.
I was charging up to 95% at work, since i was spending about 10% to get home…
Several times, i charged to 100 when i had some additional drives during the day…

You should probably meet Brian from the Overly Cautious thread. Swap anxiety stories.

Do you drive your gas cars at the redline all the time?

Between red and 1/4 tank before refilling.

I have no anxiety over this! You want to talk anxiety when Nissan first came out with the Leaf I bought one....now that was range anxiety! Kept the car less than one year.

I usually charge to 85% and it gets me 270 mile range, that was until last week. The past 2 times I charged it gave me a range of 230....where did the 40 miles disappear too ? is it going into winter mode?

2 weeks ago I went to 100% and my range was 320

No, do you push your engine to 100% of the rpm’s everytime? Why would you treat your battery any different?

Long term battery management is just reality of the technology. FYI the same thing are recommended for charging phones as well (not to constantly charge them to 100% or leave it plugged in all the time) to preserve battery life longer.

Porsche thanks you for guaranteeing their warranty will never be called upon . The next owner should kiss your feet .

Oh sorry misunderstood your question! Nope not even close to the red line but thats really not the same. I would never push this car, in fact I never have used launch control and only used sport mode once.

So, very personal take on this, based on various things I read and asked around, I am not an expert myself, but:

- Apparently what hurts battery the most especially when charging to 100% is super fast charging.

- The taycan has a buffer on top of the 100% which means that you actually never charge to 100% yourself.

- It is better not to sit for a long time on a high percentage of charge.

- Charging slowly from low charge is best.

- Recent battery tech are not impacted as much by charging to 100%

So the way I do it myself, is that I charge to 100% and let it go down to around 25/30% through my daily usage. I do the charging at home and only have a 30A charger due to condo restrictions, so it charges pretty slowly, basically take the whole night.

Overall I do not charge too often that way and because it is slow charging it is not too bad.

Again this is my personal take, and I could definitely do 85% to 30% instead unless I do a long journey but I also find it annoying so I do this instead.

Also I don't drive my car that much overall, so I doubt I will hurt the battery too much before I buy another car anyway in like 5+ years or so.

So I would say do what you feel the most comfortable with, those battery are not THAT fragile either and even if you lose a couple additional % on your car lifetime because of it, it is not the end of the world?
