Since many threads are rabbit-trailing into this discussion, let's have a thread for it!
Addressing the Facts
The way Tesla displays percentage ("energy") is as follows:
The way Tesla displays rated range ("distance") is as follows:
Which should I pick?
Just pick whichever one is the lesser evil for you. There is no absolute right answer, despite what folks on here might suggest.
Distance lies to you only if you treat it as achievable in all circumstances. You need to be aware this is rated range, not estimated range. See this thread if you want way more discussion on this.
Distance might make you feel bad because it makes degradation apparent. It's more honest, but maybe ignorance is bliss for you.
Distance could be more useful for trip estimation, simply because distance is a familiar unit in the context of driving (even if you do need to make some corrections for efficiency based on road conditions and speed).
Percentage lies to you about degradation. 100% is always possible. In fact, if the battery reports a now-lower capacity while sitting, you might see this as an increase in percentage after the correction was made, even though less energy is estimated to be available.
Percentage is great for those that are persnickety over their state of charge for battery health. Guidance on things like "charge to 80%" are easier to achieve accurately this way. You can't do this with range, because the rated range displayed at whatever 80% is will change as the battery ages.
Other Factors
During Charging
For Level 2 AC charging, they behave very differently.
Accuracy
The UI gives you more significant figures with Distance, which is kind of nice for people that keep a log of their data.
However, this can be worked around by using the trip meter.
Discuss!
And here it is, the moment you've been waiting for. Tell everyone your opinions. I got my chance, the opportunity is now yours!
Addressing the Facts
The way Tesla displays percentage ("energy") is as follows:
- Percentage displayed is the percentage of usable battery capacity.
- As the battery degrades, the percentage does not change.
- As the battery degrades, the amount of percentage consumed for a given amount of energy increases.
The way Tesla displays rated range ("distance") is as follows:
- Range displayed is based on the usable energy in rated conditions.
- As the battery degrades, the rated range declines.
- As the battery degrades, the amount of rated range consumed does not change.

Other Factors
During Charging
For Level 2 AC charging, they behave very differently.
- Distance: Shows you energy actually being added in terms of mph or km/h, after accounting for losses, climate control, etc. Net power, basically.
- Energy: Shows you input power in terms of kW, not net power to the battery. Effectively, this shows gross power.
