This is an older one. I had 90% too. Wait for 2023.26.1. Or maybe they will revert to "90%" (very low probability)2023.20.9

But they had the same batteries, as I know, due to the same dual motor (and acceleration boost option). I can't quickly find what I watched, but I focused on EU LR versions 2021-2022 (and had doubts regarding 2022 due to Rizen, which has 5% more consumption than Atom), and had been choosing between US/CN and CN won.
I don't know. I saw "551 km" maximum on a photo, when I got it, there were 95% and 521 km and that estimation was real. After that, I didn't charge till 100%. I'll pick a suitable time and try 5%->100%, but it's also good to have some OBD app.
Alex, would you mind explaining what led you to your conclusion? I would have thought the other way.Recharge daily
Smaller depth of discharge is better than running it low first then charging.Alex, would you mind explaining what led you to your conclusion? I would have thought the other way.
Thanks for the response, btw!
Ok. It's better that way also in case an unexpected trip comes up, as the SOC is held at 50%. I thought the other way only because the average SOC over time would be lower, like 35% vs close to 50% or so.Smaller depth of discharge is better than running it low first then charging.
Not sure which model/battery you have, but the difference between 35% and 50% average SoC for calendar aging is minimal and you probably won't notice it:Ok.

@AAKEE (and everybody else): here is a follow up question:
Assuming I charge to 50% at home, and for a period of time, only consume ~5% SOC during my daily commute (short drives).
Which of the two below would be better for the battery?
(1) recharge daily (go down to 45%, then recharge to 50% the same day, then repeat)
(2) don't charge daily, and let the SOC go down to 20% (5% per day), and then on day 6, charge from 20% ---> 50%. Then repeat.
-Do not charge more than needed until the next charge. (Can be any setting between 50-100% that is needed until next charge).
-Charge often. This reduces the needed SOC level above. Daily is recommended.
-Charge late, that is = shortly before the drive.
Which of the two below would be better for the battery?
Fast launch/speeding, accelerator pedal pressed down to the floor, or when speed above 180 km/h /112 mil/hWhat do you mean when power usage is more than 50%?
Batteries experience a significant voltage dip when drawing a lot of current, like for example during hard acceleration. I am guessing that's what Vlad refers to. The question is: at what point does it became damaging, meaning that the voltage drops low enough for the battery to experience accelerated degradation of some sort.There’s no problem with doing any of that at 50%. You might get slightly less power than at 80% but it’s not really noticeable enough to make a difference in daily use.
Do not think”storage degradation.”I don't get it... This is storage degradation, but what about active use degradation? When power usage is more than 50%: is it better with SoC 50% or 80%?
The warnings you saw was not Teslas warnings.And graphs said that, for example, 5% SoC is nice, but I saw warnings "Do not draw SoC below 20% too often or it will lead to degradation".
Tesla has a low voltage limit that limits the power to keep the voltage drop within safe limits. For example Tesla used quite high allowed lowest voltage initially on the M3P refresh I had. At low SPC ot was very slow, and it was the battery voltage that had a low floor limit that made the power low at low SOC. They changed it later, but its still possible to accelererate hard worh different SOC and see the low voltage limit with Scan my tesla.Batteries experience a significant voltage dip when drawing a lot of current, like for example during hard acceleration.

I have no idea though what the answer is, or even if a drastic voltage drop can cause damage. Haven't seen it discussed much here either ...
So ... Good question asked by Vlad, if you ask me!
I am 100% with your spinal cord here!Tesla has a low voltage limit that limits the power to keep the voltage drop within safe limits. For example Tesla used quite high allowed lowest voltage initially on the M3P refresh I had. At low SPC ot was very slow, and it was the battery voltage that had a low floor limit that made the power low at low SOC. They changed it later, but its still possible to accelererate hard worh different SOC and see the low voltage limit with Scan my tesla.
The cells themself has a low voltage limit of 2.5v/cell and that is way below 0% and where the car shuts down.
So the car protects the battery from too high power demands at low SOC.
Still, from using lithium batteries in applications that do not protect the battery from low SOC and high power I know that this could be bad so the spinal cord tell me
not to use very much power below 20%.
I know the car would protect itself but still I am carefull below 20%, in the same
way I do not floor the pedal woth a cold ICE engine.
The 2023 model 3 RWD (“SR) is the LFP version, right?Hi! New here and have owned a new M3SR for about a week and a half. Still learning... learning a lot. I'm charging up to 100% at home via my mobile charger. It seems like this is not the preferred or popular move.
I've read through this thread and a handful of others but am still struggling to get a clear answer. Can I safely charge to 100% with my 2023 M3SR, or am I inadvertently hurting myself by doing so? Thanks.
