I’ve had my id4 since May. Going on 6 months now. Charging from 30 or 40% to 80% to 90% at home every night. At 90% I would start the day with about 235-240 miles. Now it only charges to 200 miles at 90%.

I get that the battery might loose power over time but only after 6 months? Where am I gonna be in another 6?

Anyone else encounter this yet? I wonder if this might fall under the battery warranty.

Pennsylvania. Yea I guess it is. Only in the 50s. I forgot I was warned about that. I thought it would be at colder temperatures. Thanks for the reminder!

In general, EV battery degradation isn’t linear. A new battery will degrade more in the initial year or two, and then the rate of degradation will typically taper off.
95% of our charging is done at EA, and all but one was to 80%. With over 11,000 miles, I have not noticed any degradation at all, according to the GOM.

Everyone encounters this since the Guess-O-Meter mileage changes drastically based on your recent driving (last 100 miles or so.) So it changes often with temperature, speed, wind, rain, etc. Its not any indidcation of battery degradation. Just turn on or off your AC or heat and watch it change back and forth.

I seen no evidence of battery deg here.

Looks like colder temperatures and maybe some less economical diving recently?

Your change in forecast range has nothing to do with battery degradation. The forecast range "calculator" has adjusted to your driving style and is now more accurately forecasting how far you'll get. this includes adjusting your range forecast based on the fact that you're probably using the heater a little bit now that your temperatures are down in the 50s. You will also begin to notice that range forecast will probably begin to go up in the spring as temperatures begin to increase.

This is likely just the GOM (guess-o-meter), or range indicator estimating your range based on your driving habits. I got my ID in April and it is the same but I’m in Florida. Do a lot of slow, city driving below 55 mph and you will see it go back up again. Highway speeds bring the range down the most. Also running the heat or a/c.

As others have explained, the guess-o-meter is just that. A couple winters ago I had an Audi e-tron quattro loaner (when I had my A3 e-tron in for service) and it 31*F weather with about 70% battery it said my range was 143 miles. Turning off the HVAC increased that to 191 miles, a difference of 48 miles or a gain of over 33% !?! Audi conveniently shows you the impact of each change, like steering wheel heating and left front seat heating cost 3 miles of range, etc. The ID.4 leaves us guessing as to what is responsible for GoM changes.

Yeah, the range meter just goes by how you’ve been driving. Drive like grandma for a few charges and watch it shoot up…

VW really needs to do a better job explaining the GOM, someone already mentioned this, but it's just going to continually come up as more and more ID.4s hit the road.

I wasn't a pre-order, I just got super lucky that when I was going to look for new cars. I was in the market for a new car and happened to stop at VW for a Jetta appraisal .They happened to have literally just gotten a shipment and had an FE. I said I need a day to move some money around, check the numbers etc., and asked if they would hold it for me (they did) and I walked away the next day with it.

Not once did anyone tell me about the GOM, very little info about the EV battery's, just the basics, i.e., it degrades over time. They also didn't tell me that the charging to 100% should only be done when you need the range. I get its a turn-off for some and the opposite of a selling point, but that's the reality of owning an EV and being an "early adopter" of newer tech. They could definitely use a little more transparency. If they and the rest of the world want people to switch from gas to EV's they just need to be upfront about everything.

Winter is Coming.. Or arrived already.

When it's cold it's consuming more. Need to warm the battery (if under 12c) and as result your Guess!!! - o-meter will take it in account what your approx range will be with history it knew in driving style (last 50mi orso) and also the current consumption. Some calculation happens and your range will be shown.

You won't hit the the summer ranges anymore till.. You guess it right.. Its summer.

Normal for any EV

It’s still just looking at last XX miles/kilometers, do you think? Or does it really take into account weather? I’m guessing the former… (PS: Thanks for all the informative YouTube videos?”!)

The car just looks at the last miles driven as well as current consumption.

If you have a garage and plug in regularly, set the car to preheat before you leave. This way the heater doesn't draw power from the battery to heat the cabin. Once warm the car will require less power to keep it warm.
