Slider for charge percentage not accurate?

This site may earn commission on affiliate links.
There are a bunch of people that charge to 80% or 90% and then project their total range at 100%.

Well, I've found out the grid lines in the display are not set to 60%, 70%, 80% or 90%. At least in my car.
Could you check in yours?

These lines are clearly set at 61%, 71%, 81% and 91% in my car.

You can test it in different ways.

The easiest way is to set the car to 90% using the App. The grid lines in the App are not distorted.

So, set the car to 90% in the App and then check in the car where is the charging line.
You may see it's well above the 90% grid line as in my car.

You can also test it by setting the car to charge to 80 or 90% (in the car's display) and then set the display to %.
I always get 81% or 91% when the charging finishes instead of the 80% or 90%.

Is this a normal behaviour shared by all cars or only by a subset?

There’s no dirty trick going on. The problem with using the slider in the car or the tesla app is that there’s no feedback other than 90% and 100%. So it’s virtually luck to get it exactly to any other percentage. You need to use an app like stats or any other app that lets you set the charge rate to a specific percentage if you want to be exact.

Not really. The app snaps every 1%. It's not that difficult to set it to 80% exactly. Really. Try it. Then you check on the car display and it's clearly below 80%.

With the car set to percentage And the latest updates you can slide the slider to a certain percentage....but there’s not feedback like 90 or 100%.

Digital displays with numbers have fooled too many people into thinking that precision is the same as accuracy. If I weigh myself on a digital scale, and it says 180 lbs (that's a precise number), that doesn't mean my true weight can't be between 178 and 182 (that's accuracy). Expecting better than 1% accuracy on the charging estimate or battery remaining capacity estimate is foolish. If you get better than 2% accuracy, then give Tesla a big browny point for being careful in their algorithms. It wasn't so long ago that 2% accuracy was only expected on dedicated meters.

Nope.

Mine snaps at what looks like the 100% mark and at the 90% mark, just as others have said, and does not do so at anything lower. (iOS, latest version of the app).

FWIW I seem to have the opposite issue as what's discussed here- my "snap" at 90 shows only "89%" on the left side and indeed shows the car charged to 89% when charging finishes.... this HAS changed relatively recently as that same mark for 90 used to actually be 90 and charge the car to 90.

I don't really care enough about 89 vs 90 to fiddle with it further though.

Yeah, I wrote it the other way around in the first post by mistake but could not edit it anymore.
It's more noticeable on 60, 70 and 80%. Thanks for your reply.

Thank you nightshade for using the correct term for how the app responds at 90% and 100%. "SNAP" are you a video editor by chance?

I found this thread after noticing this phenomenon myself. I took delivery the day of the last post above. Aver since new, the app charge limit slider always snaps to 90% or 100%. As of yesterday if I change snap to 90% in the app it actually sets the charge limit to 89%. I know this is a first world problem but it is interesting non the less. Yesterday I noticed it briefly went back to normal and now today it's back to the -1% settings again. Fascinating. haha.

I'll report back if I discover the cause.
