I have to remember myself to not think about charging the model 3 like I’m charging my phone. Even at 60% charge I have close to 200 miles. I don’t even get gas till I’m down to 80 miles left. So I should just charge to 50-60% around town. And 70% when going to work.
And actually, we should also start charging our phones and tablets and laptops more like our cars.
In iOS13 (beta) Apple is now learning what time you get up and will only charge to 80% and then does the 100% right before you alarm goes off.Exactly.
And actually, we should also start charging our phones and tablets and laptops more like our cars. Leaving them plugged in overnight at 100% isn’t so hot for them. Unplug them at 90% if you spot it there ... otherwise unplug it when it’s done and let it drain a bit overnight instead of staying at 100% plugged in. This is what I do with all my devices since learning about the batteries a lot more via the car.

Wonder if the upcoming Smart AC charging may have a similar feature?

You don’t know that it is “absolutely fine”. If 90% isn’t required it can’t hurt to lower to 80% or 70%, and if you believe the experts, it can actually help to do so.
Yes, I do. Elon has suggested it and there is no real evidence with the Model 3 battery that says otherwise. Last I heard Elon says that they are trending toward 300,000-500,000 mile averages for the Model 3 and it's battery.
Can you show many anywhere here Tesla indicates that charging to 90% isn't safe for the battery? And don't start back with the experts graphs crap, real numbers for the Model 3 batteries. Oh, they don't exist?
In general ALL systems can benefit from limiting extremes. No doubt that the 2170's is one of the most tolerate and resilient lit-ion batteries mass produced PERIOD. But it is still governed by ALL the general rules that apply to lit-ion batteries.Yes, I do. Elon has suggested it and there is no real evidence with the Model 3 battery that says otherwise.

80 or 90% depending on how I feel that day. Also sometimes 85% when I can’t decide
100% for road trips
Took delivery of model 3 SR+ yesterday and observed the following on the recommended charge level out of the box by Tesla. Looks like by default Tesla recommends 90% charge daily and 100% charge on trips.
Am i reading this correctly?
Is it safe to charge to these levels?
I dont need 90% charge for my commute but dont mind charging it to 90% for peace of mind if it does not affect battery life over long run 6+years.
Thanks
This is long overdue. It still bothers me a lot that only a few manufacturers of laptops offer the functionality to set a more battery healthy upper charge limit like 80%. Lenovo and Samsung do, and maybe one or two others, but a lot of the other major ones like HP, Dell, Apple, etc. don't offer it, and it just trashes laptop batteries having them sit at 100% constantly, since a lot of people leave their laptops plugged in a lot.In iOS13 (beta) Apple is now learning what time you get up and will only charge to 80% and then does the 100% right before you alarm goes off.
Refer to @elonmusk tweets that preferred 80% to 90% for long term health. This implies he believes that 80% is better. If 80% is better, by definition 90% is not better, and at best equal, if not worse.
How much worse? We don’t know. 1 mile difference after 500,000? 10% difference?
Catastrophic cliff fall-off at 600,000 for 90% but 700,000 for 80%?
Who knows.
If it’s easy choose lower, go with lower for some unknown future benefit ... why NOT?
So why not add that disclaimer to the end of your suggested rules "Who knows"?
Exactly my point. People are already worried about their new EV and how long the battery is going to last. They already know how long their iPhone battery lasts and so they really want to make sure that the car does better. It doesn't take babysitting to make the car battery last longer. In fact, with some of the abuses that I've heard (multiple Supercharging daily, batteries in auction lots going to 0) you would think that there are tons of replacements being done today. (There was some periods in the past)
But they aren't
I favor helping people get over their range and battery anxiety. I can't count the number of people who have said that they can't charge to 100% because it will hurt the battery, and I believe even you know that's just not true.
Tesla is the one that has to honor the battery warranty. If they felt that they were going to have budgetary issues honoring it, don't you think that they may even add slightly more guidance than a sentence or two that I think has maybe even been around since the Roadster???
