Porche Taycan Battery Drain Test: It Can Last For 5 Years In Your Garage


Porsche Taycan may not have a range greater than Tesla Model 3 or its arch-rival the Model S. However, the Porsche Taycan battery drain is so slow that it will not drain completely even if you leave it for more than 5 years. It seems like a bit of exaggeration but let me explain my point.

In terms of battery drain, Porsche is nine times more efficient than Tesla Model 3. The battery of Porsche Taycan drained only 1% during a span of 22 days.

Bjorn Nyland, a YouTuber, uploaded a video on his channel explaining everything about this test. Since Bjorn doesn’t have a Taycan, he instructed the owner to conduct the test and record it. Previously, the YouTuber has also conducted a battery drain test for the Tesla Model 3.

Bjorn is an electric vehicle enthusiast and keeps on sharing stuff regarding electric vehicles.

Bjorn guided the owner to charge his Porsche Taycan up to 90% and to leave it for 22 days. The owner then checked his car a couple of times during this time period. Here’s everything you need to know about what happened.

Better Than Tesla Model 3: Porsche Taycan Battery Drain Is 1% In 22 Days

On 16th April 2020, the owner of Porsche Taycan charged his car up to 90% battery with an electric range of 324 km. After that, he turned off the monitoring app as well as his car.

On the 10th day on 26th April when the owner turned his car ON, the battery was reduced to 89% but with the same 324 km battery range. The owner said the one percent battery may be consumed upon the activation of air suspension when the car starts.

The owner again checked after 15 days and the car was still at 89% with a 1 km drop in the electric range. He repeated the procedure until it reached 22 days.

Finally, after 22 days when he checked in on 8th May 2020, the Porsche Taycan battery was still at 89%. However, the range was reduced to 321 km. It’s probably because the odometer shows the battery percentage only in integers and the range reduces as in terms of kilometers traveled.

After doing a bunch of calculations, Bjorn explained that for 22 days the Porsche Taycan had consumed 1.52W only.

On the other hand, Tesla Model 3 consumed 10% of its battery with a total consumption of 13.3W in the same time period. If we compare both then the Model 3 battery drain is way higher. It’s almost 9 times that of Taycan.

Porsche Taycan Battery Drain_ More efficient than Tesla

At first, we thought that maybe because of sentry mode the consumption rate was higher in Tesla Model 3. However, everything including the sentry mode was off.

Furthermore, Bjorn said in the video that his old Model X that didn’t have sentry mode has an even higher draining rate.

Final Thoughts

Porsche Taycan Battery Drain_ More efficient than Tesla (1)

Bjorn said that it’s something related to the computer hardware of the Tesla. The computer must be functioning or running some software while it was turned off that led to the consumption of the battery.

However, Porsche Taycan also responded to wakeup calls while it was off. So it’s more about the question of optimization.

We don’t know what exactly is draining the battery of Tesla Model 3 when it’s not working. We can only suggest Tesla and its engineers look into the matter and see if there’s an issue that needs fixing.

What do you guys think about the matter?
