It's a beautiful thing......

I think he might mean he wants to limit how much his phone charges to prevent battery degradation.

Correct.

Is charging regularly to 90 percent too much?

I have regularly charged my Model S 70D to 90% for 2 1/2 years and 30,000miles, and I have only lost 2 miles of range. Would I have lost less charging to 80%? Who knows, but I'm not sweating it.

To explain further, if an EV had two charge settings (such as 80% for routine use and 100% for trip), the EPA said it would average the range of the two settings and that’s what could be advertised as the EPA rated range. This is one reason Tesla now has the slider, so there aren’t two settings for the EPA to average. The original firmware for the Model S had two settings, daily and trip, and daily was 92% or 93% as I recall.

Would be nice if you could simply set the time you're going to start you trip and have the car handle charging to 100% when you're ready to leave.

I thought the app/UI DID permit that?

As far as I know no. It lets you schedule a time to start charging which is fairly simple since you should know the charge per hour you normally get
I'm just looking to make it even easier. In the scheme of things this would be low on my list of priorities though. Would rather see increased use of voice commands to reduce the amount of time I need to interact with the screen.

You’re right, the math is simple for the UI to know exactly when to start to reach the desired % right when we would plan to drive. Maybe it’s another future firmware update.

Yep. This is possible with Android using a 3rd party app. If I don't get too lazy I'll use it in the summer and see about doing the same for our Chromebooks.

Is 314 the max for the Model 3LR? Hmmmm.

while we're on the battery topic, which way is better, charging everyday so that you'd be at 80% (or 90% for that matter) every morning, or wait until it drops to about 20% and charge?

Plug in every day if you can and let the battery management system manage the battery. There is no advantage to waiting until the charge is low, and in fact Tesla recommends against it. It’s in the owners manual IN BOLD AND UPPER CASE LIKE THIS so Tesla must think it’s important. Just make it a habit to plug in when you get home, soon it will be routine and you’ll never have to think about it.

The Model S used to come with a card that says “A connected Model S is a happy Model S”.

Some of us do not always have convenient way to charge. Is it really bad to charge twice a week?
