I tried before but the current is so low that it doesn't charge fast enough to overcome the drain.
I am using a usb cigarette port charger that works like a charm.
I don't think it will affect the car battery.
As of phone battery, my thought is that because our car is new, the battery and alternator is all new, the voltage and current would be stable, so it will be ok for the phone.
There's also a fuse in the usb charger just in case.
On top of that, if I remember correctly, I was once told that there's voltage stabilizer or current stabilizer chip in the phone so it should not be a threat.
I am no good with electronics, maybe some sifu can advise oso.
Do you guys train the transmission?
I am not sure what I am going to say is valid or perhaps its only my own perception.
I have not always been light on the peddle since day one.
Sometimes took it for some hardcore speed drive with D mode, just simply step on the peddle and let it rev up to accelerate on a clear road.
By doing this, I believe that I am giving more data to the transmission computer on the average rev that it should change gear.
I do not have juddering problem since 2000km mileage and I am at 7000km mileage now.
At crawling speed, the gearbox would not try to change gear and judder as my gear change from 1 to 2 will happen at 2000rpm.
I am sure that most existing owner already get use to it and no longer a concern.
For new owner, you will feel concern but after awhile, you will know how to avoid the juddering.

Juddering at low speed is minimal for me. Only the suspension feels a bit noisy to me especially when going up concrete grooved ramps or bad roads.
